BALL AND BEAMER: GENUS ATHYSANELLA i

ge paper deals with the species of the following genera of leaf hoppers in North America north of Mexico: Athysanella Bk.; Gladionura Osb.; Amphipyga Osb.; Pectinapyga Osb.; Gillettiella Osb.; Doratura Shlb. (in America) ; Brachydella n. sub. g. and Pedu- mella n. sub. g. Gladionura and Amphipyga are reduced to sub- genera of Athysanella, Pectinapyga is placed as a synonym of Am- phipyga, and Doratura is reported for the first time in this country.

The revision was begun several years ago because of the inability to classify satisfactorily the great amount of material then in the Snow Entomological Collection and the private collection of the senior author. Doctor Ball’s serious illness in February, 1937, very materially handicapped the progress of the work. However, in spite of this misfortune it seemed best to go ahead and finish the paper, omitting all host-plant records and life-history material, in the hope that Doctor Ball will again be able to go ahead with that portion of the study at some future date.

Many thousands of specimens have been examined. Aside from all the material that was in the collections of the country, the Bio- logical Survey of the University of Kansas made this group a “spe- cial order of business” in the summers of 1935, 1936 and 1987, visiting especially those regions known to be most suitable to these insects. Special effort was made to obtain better series of some of the forms represented by too few specimens. As a result we have been able to study a great many individuals of most of the species. We have also been fortunate in being able to study all the available type material.

ACKNOWLEDGMENTS

We desire to express our appreciation to all those individuals and institutions who have so generously aided us with loans of specimens. We are especially indebted to P. W. Oman of the United States Na- tional Museum for much helpful advice and comparisons of type material and to Dr. J. N. Knull of Ohio State University for the privilege of studying the Osborn types.

DISTRIBUTION

The members of this group of leaf hoppers are pretty well scattered over North America, but since they feed entirely upon grasses and the most of them upon the so-called ‘“‘short-grasses,”’ we find a con- centration of species in the desert. regions of the Southwest. Ari- zona, New Mexico, Colorado and Kansas have yielded by far the most of our forms. Some of the species seem to have a wide dis-

(9 a)

tribution, while others are quite restricted. This can probably be correlated with food-plant distribution.

TECHNIQUE

This study is based largely on male external and internal genitalia. Slide mounts are made by removing the abdomen of the male, plac- ing it in ten percent caustic for a short time (1-2 minutes) until cleared, transferring to water, then to a drop of glycerine, where the pygofers are removed from the plates by splitting the body wall along the sides and rupturing it about the base of the aedeagus. These two portions are then mounted in diaphane inside down on glass slides. Cover slips are pressed uniformly in place in order to give each structure as nearly the same view as possible. Negative prints on photostat paper have been made from these slides by projection and are used in our plates.

DIAGNOSTIC CHARACTERS

The head-shape and the type of male genitalia are used for generic separation. The presence or absence of a spine on the hind tibia, to- gether with the shape of the pygofer of the male, forms the basis for subgeneric distinction and the shape of the male plates, styles, aede- agi, and the last ventral segment of the females plus the usual pres- ence or absence of round, black spots on the margin of the vertex, forms the basis for the separation of species. Genitalic characters have proven much more stable than vertexal or color.

Each species usually has both a short- and a long-winged form, especially in the female, the short-winged individuals predominating During our study of thousands of individuals we have been im- pressed by the numerous examples of freaks of both sexes; that is, specimens in which both internal and external parts of the genitalia are only partially developed. As to what may have caused this ab- normality we have no suggestions to make. It has not been un- common to find one freak in every twenty-five specimens. It is entirely possible, therefore, as has occurred, to have one of these undeveloped individuals described as the type of a species.

TAXONOMIC POSITION This group of leaf hoppers belongs to the subfamily Jassinae, which is distinguished from other subfamilies of the Cicadellidae by having ocelli on or near the margin of the vertex. They are usually

short winged with indistinct venation and the females usually have long, sharp ovipositors,

THE GEenus ATHYSANELLA

C. F. Baker described the genus Athysanella in 1898 (Psyche, Vol. VIII, p. 185), designating A. magdalena Bk. type. In 1930 (Ann. Ent. Soc. Am., Dec., pp. 687-721) H. Osborn, in a revision of the genus, described four new genera: Gillettiella, Pectinapyga, Am- phipyga, and Gladionura. After a study of the many thousands of specimens the authors were convinced that a truer picture of rela- tionships would be shown by retaining Gilletiella, placing Pectin- apyga as a synonym of Ahphipyga, and reducing Gladionura and Amphipyga to subgenera of Athysanella. To complete this picture it was necessary to describe two more subgenera: Brachydella and Pedumella. ,

These leaf hoppers are usually small, less than 6.5mm. in length, with vertex angled to rounded, usually brachypterous, some long winged forms present in each species, venation indistinct, ovipositor of female usually long and sharp and male genitalia usually large and of a more or less open type.

BALL AND BEAMER: GENUS ATHYSANELLA D7

23. Athysanella (Amphipyga) ardua n. sp.

Resembling teres Ball and Beamer, but easily separated from it by the enlarged apex of the fingerlike process of style and by the plates being much longer than the valve. Length: Male, 3 mm.; female, 4.75 mm.

H. Beamer. Holotype, allotype and paratypes in Ball collection, paratypes in Snow Entomological Collection.

25. Athysanella (Amphipyga) rubicunda n. sp.

Resembling the light form of nzgrafascia DeL., but easily sepa- rated from it by the pink color, by the excavated apices of male plates, the long, diverging, ventral processes of aedeagus and the longer process on the last ventral segment of the female. Length: Male, 3 mm.; female, 3.5 mm.

Structure. Vertex bluntly angular, slightly wider between eyes than median length. Elytra short exposing about five abdominal segments.

Color. Stramineous tinged with pink, process of last ventral seg- ment of female darkened.

Genitalia. Last ventral segment of female with lateral margins rounding to very long, quadrangular median process occupying one- third width of segment. Male valve slightly more than right angle; plates about as wide as valve at base, lateral margins sinuately converging to concave apices, inner margins slightly diverging near apex. Aedeagus almost a straight tube with a pair of ventral proc- esses arising at base, diverging, almost as long as shaft. These processes are unusual in the genus.

{rusion angular instead of rectangular. Length: Male, 3 mm.; fe- male, 4 mm.

Vertex more or less rounded, margins rounding, color cinereous with more or less darker markings; vertex often with more or less indefinite dark marks; pronotum with usual cross row of spots; elytra from semihyaline with lighter veins to dark brown longi- tudinal bands; dorsum of abdomen with usual rows of brown spots.

Genitalia. Pygofer of male very slightly narrowed to rounded apex with peculiar angled process on inner margin; valve about as long as preceding segment, obtusely angled; plates wider at base than valve, sides slightly narrowed to truncate apices with rounded corners; style enlarged on outer half, widest just before apex, outer margin longest; aedeagus in lateral view almost straight, slightly narrowed at middle, with a peculiar, serrated protrusion on outer fourth on ventral margin.

27. Athysanella (Amphipyga) nigrofascia DeLong and Davidson

Amphipyga nigrofascia DeLong and Davidson, Jr., N. Y., Ent. Soc., No. 2, Vol. XLII, p. 222, 1934.

This species was described from two males from Lodi, Cal. The female is here described for the first time.

Length, 3.75 mm. Colored as the male. Last ventral segment more than twice as long as preceding, lateral margins rounding to a very long, black, rectangular, median projection, occupying about one-third posterior margin.

Allotype female described above, Antioch, Cal., July 30, 1935, R. H. Beamer.

This species is quite variable in color. Out of the 73 females and 70 males taken at the above place and time, about 40 each, males and females, were typically colored, the remainder lacking any dorsal black markings, the projection of the last ventral seg- ment of the female retaining the only dark coloring. National museum material collected in California in 1935 by P. W. Oman showed a variation from almost entirely black individuals to en- tirely light ones. Male internal genitalia were identical in both forms.

Allotype in Snow Entomological Collection.

30 THE UNIVERSITY SCIENCE BULLETIN

28. Athysanella (Amphipyga) triodana n. sp.

Resembles occidentalis (Baker), but lacks most of the black markings; the last ventral segment of female is much broader, more nearly truncate and with lateral margins sharply excavated; pygo- fers broadly rounded and the styles slender and evenly tapered from lateral projection instead of spatulate. Length: Male, 2.75 mm.; female, 4 mm.

Vertex flat, margins rather rounded.

Color from stramineous to cinereous, usually not much color ex- cept usual spots on dorsum of abdomen. Some specimens have frontal ares quite black, giving a darkened appearance to the whole face.

Genitalia. Last ventral segment of female not quite twice as long as wide, lateral margins narrowly and sharply excavated to a very broad and long median projection, which is almost truncate. Male pygofer slightly narrowed apically; valve obtusely angled; plates as broad as valve at base, lateral margins sinuately rounded to semisharp apices, mesal margin diverging on outer half; styles on outer half long and slender, gradually tapering to sharp apices.

30. Athysanella (Amphipyga) texana (Osb.)

Pectinapyga terana Osborn, H. Ann. Ent. Soc. Am., P. 697, 1930.

Gladionura aridicola Osborn, H. Ann. Ent. Soc. Am., P. 707, 1930.

About the size of occidentalis, but with vertex flat, margins flat and lacking round, black spots. Length, 2-4 mm.

Vertex flat to excavated, margins sharp; style not usually visible externally.

Color cinereous, varying from almost without dark marks to quite heavily marked specimens.

Gemtalia. Pygofer of male narrowed to a triangular shape with apex rounded, apex containing a small comblike plate; valve shorter than preceding segment, angular; plates wider at base than valve, strongly constricted on outer margin near middle, apices rounded; style enlarged on outer half with a deep and sharp angular excava- tion on outer margin, apex sharp. Last ventral segment of female longer than preceding, posterior margin shallowly excavated either side a broad, slightly protruding middle portion.

Types examined. Specimens at hand from Kansas, Oklahoma and Texas. The Kansas specimens are quite consistently larger than the Texas forms.

The presence of the comblike structure does not seem sufficient for generic rank, especially when we find species like nimbata and triodana which are so like texana, but do not have this structure. The genus Pectinapyga is therefore placed in the subgenus Am- phipyga.

The female Holotype of Gladionura aridicola Osb. was examined and is unquestionably a specimen of texana, it therefore becomes a synonym of this species. The male allotype of Gladionura aridi- cola is a specimen of Athysanella yumana Osb.

32 THE UNIversity SciENCE BULLETIN

31. Athysanella (Amphipyga) anzana n. sp.

Resembling playana, but smaller, plates of male longer, finger of style shorter, more slender, with a distinct excavation between it and apex of shaft, and aedeagus much shorter with larger. serrated apex. Length: Male, 3 mm.; female, 4 mm.

Vertex flat, margins rather acute, styles of male usually exposed.

Color cinereous, usually with dark marks; vertex with two small black spots on margin either side of apex and two short diverging dashes just back of apex; pronotum with a semblance of cross row of spots; elytra and abdomen with usual longitudinal dark stripes.

32. Athysanella (Amphipyga) balli Osb.

Amphipyga balli Osborn, Herbert, Bull. 14, Ohio Biol. Survey, 1928, p. 289.

A beautiful species with its black spots on margin of vertex, its dark oblique vittae of elytra, and characterized by the fingerlike projection on inner margin of style and widely separated triangular plates, with very short inner margins.

Genitalia. Pygofer of male almost rectangular; valve about as long as preceding segment, angular; plates broader at base than valve, short, about as long as valve with truncate apices; style en- larged on outer half, angularly excavated on outer fourth leaving a fingerlike projection.

Holotype female, Marietta, Ohio, September 13, 1905; allotype male, Columbus, Ohio, July 22, so labeled in Osborn collection are here designated.* Other specimens are at hand from Kansas and lowa.

* Professor Osborn in his revision of this group of insects in the Annals, 1930, is often indefinite and failed to follow a uniform practice in his designation of types. Designations will be made and his intent followed wherever possible.

33. Athysanella (Amphipyga) stylata Osb.

Amphipyga stylata Osborn, Herbert, Annals Ent. Soc. Am., Vol. XXIII, p. 694, 1930.

Resembling reticulata Osb. very closely, but may be separated from it by the more rounded apices of the male plates, by the longer fingerlike process of the style, by the shorter aedeagus, with one point at apex, and by the posterior margin of last ventral segment of female being convex.

Vertex flat to convex, margins rather sharp; styles of males usually exposed.

Color cinereous with darker markings; vertex with two or three black spots on margin, usually a pair of dashes just back of apex and often a pair of comma-shaped marks at base; veins of elytra often light with dark longitudinal stripes more or less in evidence.

Gemtalia. Pygofer of male broadly rounded. Valve obtusely rounded; plates about as broad as valve at base, very slightly nar- rowed on outer margin, inner margin broadly separated, diverging to rounded apices; styles with right-angled notch near outer third, inner fingerlike process about one-third longer than width of shaft at notch; aedeagus in lateral view widened and ventral margin serrate on outer half with small tooth at apex. Last ventral seg- ment of female with lateral margins slightly produced, posterior margin evenly rounded from these small projections.

Holotype female, allotype male, Grand Junction, Colo., H. Osborn, so labeled in Osborn collection are here designated. Numerous specimens of both sexes are at hand from Palisades, Colo., August 16, 1936, R. H. Beamer.

34. Athysanella (Amphipyga) reticulata Osb.

Amphipyga reticulata Osborn, Herbert, Annals Ent. Soc. Am., Vol. XXIII, p. 691, 1930.

Resembling balli Osb., but without heavy, dark markings; is larger, aedeagus longer with larger ventral serrations, male plates longer and sharper and posterior margin of last ventral segment of female is excavated instead of produced. Length: Female, 4 mm.

Vertex hardly flat, margins rounded.

Color cinereous; vertex with two round, black spots; elytra with veins lighter, with tendency to brown longitudinal stripes; abdomen with usual spotting. ;

Genitalia. Male pygofer broadly rounded. Valve obtusely angled; plates as broad as valve at base, mesal margins separated at base, sharply diverging to sharp apices; styles with right-angled notch at apex, fingerlike inner process about as long as width of shaft at

notch. Aedeagus in lateral view with sides almost parallel, ventral 3—2181

34. THE UNIVERSITY SCIENCE BULLETIN

margin roughly serrate, apex apparently with two teeth. Last ven- tral segment of female with lateral margins produced, posterior margin excavated with slightly produced median tooth.

Although the original description says “Described from two fe- males from the collection of E. D. Ball, Elsinore, Utah, April 22, 1906,” there are three females in Doctor Ball’s collection from Elsi- nore, Utah, 2 with paratype labels and one with the printed word “Type.” This latter specimen is here designated holotype. The male, Monroe, Utah, July 25, 1906, described above, does not have black spots of vertex, so it is not here designated. Types in Ball collection.

35. Athysanella (Amphipyga) aridella Osb.

Amphipyga aridella Osborn, Herbert, Annals Ent. Soc. Am., Dec., 1930, p. 693. Amphipyga californica Osborn, Herbert, Annals Ent. Soc. Am., Dec., 1930, p. 696.

This species resembles occidentalis, but is usually more reddish in color and characterized by a distinct tooth on the outer margin of an otherwise rather blunt pygofer. Length, 1.75-2.25 mm.

Vertex not flat, margins rounded; style of male not exposed.

Color stramineous with a reddish tinge with two large, round, black spots on margin of vertex, and sometimes a tiny apical spot.

Genitalia. Pygofer of male narrowed to blunt apex with a sharp tooth on ventral corner; valve about as long as preceding segment, obtusely rounded; plates broader than valve at base, sides converg- ing to rounded apices; style enlarged on outer half, clavate with rounded apex; aedeagus in lateral view with sides almost parallel, curved dorsally, ending in a light hook, in ventral view enlarged on outer half, margin serrated, apex sharp. Last ventral segment of female about as long as preceding, lateral margins rounded, poste- rior margin slightly excavated from lateral lobes to a median lobe of about same length.

Holotype female and lectoallotype male, Tucson, Ariz., Herbert Osborn, are here designated.

Although no types were designated in the original description, a female from Tucson bore a holotype label. Another female from Mojave, Cal., bore the allotype label. Therefore, some error in placing this last label was made. A paratype male from the Osborn collection is therefore chosen for the lectoallotype.

36. Athysanella (Amphipyga) obesa n. sp.

Resembling aridella Osb., but much larger, male plates much sharper, styles more slender, and last ventral segment of female with lateral margins rounded to slightly excavated posterior mar- gin. Length: Male, 3 mm.; female, 4 mm.

BALL AND BEAMER: GENUS ATHYSANELLA 37

39. Athysanella (Amphipyga) hamata n. sp.

Resembling acuticauda, but male pygofers about half as wide, plates sinuate on inner margin, styles with apical outward turning hook and last ventral segment of female with lateral angles round- ing to a broad curved median projection. Length: Male, 2.75 mm.; female, 4mm.

Vertex flat, margins rounded; style not exposed.

Color cinereous to yellowish-green; usually with two large and one small black spot on margin of vertex; elytra with veins usually lighter, with or without dark markings; abdomen usually with cus- tomary dark spotting.

Genitalia. Pygofer narrowed apically to about one-third median width. Male valve obtusely angulate, plates as broad at base as valve, concavely narrowed on both margins to rather sharp apices. Styles long, swollen on outer third, sharply narrowed to outward curving hook at apex. Aedeagus almost straight in lateral view, much thicker at base than at apex, ventral serrations fine.

Holotype male, allotype female, 7 male and 11 female paratypes, Santa Fe, N. Mex., July 20, 1936, R. H. Beamer; one paratype, Antonio, Colo., August 5, 1900; 4 male and 7 female paratypes, Laramie, Wyo., July 30, 1985, P. W. Oman. Types and paratypes in Snow Entomological Collection. Paratypes in Agricultural Col- lege Collection, Fort Collins, Colo., and United States National Museum. A nice series of what is apparently this species are at hand from Pecos, N. Mex., P. W. Oman. They lack the round, black spots on the margin of the vertex and are therefore not in- cluded in the paratype series.

Lectoholotype brachypterous female, Fort Collins, Colo., August 18, 1935, C. F. Baker (Colorado, 1600), bearing Baker’s red deter- mination label. Lectoallotype, brachypterous male, Fort Collins, Colo., August 6, 1895, C. F. Baker (Colorado, 1589), are here des- ignated. Types in United States National Museum.

This is one of the commonest species throughout its range. Speci- mens have been examined from Kansas, Colorado, New Mexico, Texas, Oklahoma, Arizona, Utah, Montana, and Wyoming.

Types of the species placed in synonymy have been examined. Those of alto Osb. are specimens of attenuata that lack the black spots, a common occurrence. In extrusa the females are all attenu- ata and the males another species. Since a female was designated and labeled holotype, the name must fall. The original difficulty ‘ame about through the incorrect association of a male for attenu- ata, thus dislocating several forms.

The types of Athysanella (Gladionura) abbreviata Osb. have been studied. The type female (holotype), as Professor Osborn says in the original description, is an abnormal individual. The allotype male is larger than the female, something that rarely, if ever, occurs. Numerous specimens like this male have been taken associated with females in Kansas, Texas, Colorado, and New Mexico, and in none of the hundreds of females examined has one been found that could be said to resemble the holotype female of abbreviata. It is the con- clusion, therefore, that the male allotype is wrongly associated and that the female holotype is an abnormally developed female of Athysanella (Gladionura) sinuata Osb., since specimens of this latter species have been examined that resemble quite closely this abnormal individual.

Pygofer of male short, rectangular; valve short, ob- tuse, barely visible externally; plates broad at base, sinuately nar- rowed on outer margin to broadly rounded apices; aedeagus in lateral view broad on basal half, bent dorsally just before middle and much narrowed to apex; styles with peculiar flaplike process near attach- ment to plates, shghtly broadened for about one-fourth distance to tip, then sharply bent dorsally and narrowed to long, slender, cury- ing apices.

Numerous specimens are at hand from Wisconsin, Michigan and Massachusetts. Long-winged females are fairly common.

There is apparently no difference in the specimens in this country and those in Europe except these are smaller in size. The internal genitalia of the male are alike too, except smaller.

A Contribution to the Taxonomy of the Subfamily Issinae in America North of Mexico (Fulgoridae, Homoptera)

KATHLEEN C. DOERING, Department of Entomology, University of Kansas

Part III

Asstract: This paper comprises the third part of a monograph dealing with the taxonomy of the subfamily Issmae (Fulgoridae, Homoptera) in America. North of Mexico. In Part I* the genus Dictyssa was discussed. In part II + a key to the genera was given and the following genera were discussed, Buthiscia, Hysteropterum, Dictyonia, Dictyssonia, Dictyonissus, Neaethus, Misodema, Ulixes, Tylana, Trarus, Thionia, and Picumna. In the present paper seven genera have been revised, namely Dictyobia, Dictydea, Osbornia, Papagona, Bruchomorpha, Danepteryx and Tylanira. Tylanira Ball is a mono- typic genus to date. The genus Papagona has two species, as does Osbornia, although the latter has one color variety. The genus Dictyobia has four species, Dictydea seven, Danepteryx six, and Bruchomorpha twenty, making a total of forty-two species studied in this section of the work. Of this total number the following species are described as new: Dictyobia varia, Dictydea valida, Dictydea uhleri, Dictydea nigrata, Bruchomorpha keidensia, Brucho- morpha rosea, Bruchomorpha beamert, Bruchomorpha nodosa, Bruchomorpha tenebrosa, Bruchomorpha bunni, Danepteryx adiuncta and Danepteryx robusta. A color variety of Osbornia arborea was described and named var. fusca.

Some of the older species have been redescribed and comparative notes and drawings are given for all species except the following, which the writer has not seen: Dictydea falcata Van Duz., Dictydea variegata Van Duz., Papagona papoosa Ball, and Tylanira bifurca Ball. The male genitalia have been figured for all species except Dictyobia combinata, Dictydea uhleri, Bruchomorpha nodosa, Bruchomorpha bunnt, and the four listed above.

Synonyms in this paper, all of which are in the genus Bruchomorpha, are as follows: B. nasuta Stal=B. oculata Newman, B. flavo-vittata Stal =B. dorsata Fitch, B. bicolor Metcalf = B. vittata Metcalf and B. bimaculata Dozier = B. jocosa Stal.

The characters which have been of most value in classification of these species are the male genitalia, the shape and position on the body of the tegmina, the wing venation including the fineness or abundance of reticulation. the shapes and position of both the frons and the postelypeus.

Tue GeNus Dicryopia Uhler 1889

Uhler, P. R. New Genera and Species of American Homoptera, Trans. Md. Acad. Sci. 1, p. 39, 1889.

Comparative notes. Tegmina opaque, dark brown to black, with vitreous spots and bands, abbreviated oblong in shape, broadest just at middle, held more or less horizontal to body and about same length as body; reticulation moderate, with cells of apex much larger than rest; venation tending to follow the following pattern: Veim Se, present, setting off a broader costal margin than in Dictydea, vein Se, and R branched near base, vein M branched posterior to apex of clavus, vein Cu divided before middle, each of these veins combining again before apex where they are all connected by an apical vein which circumscribes the cortum and thus sets off a dis- tinct apical membrane. Hind wings mere scales. Hind tibiae with two spines.

This genus resembles Dictyssa, Dictydea, Dictyssonia and Neae- thus more than any others in the subfamily. From Dictyssa it is separated by its larger body size and much longer tegmina with an undulating surface. From Dictydea it is separated by its much broader wings with rounding costal border while in the latter the costal margin is straight and the tegmina are held vertically against body. It differs from Neaethus mainly by having the tegmina sub- angulately expanded before middle, ramosely reticulate and with the areoles usually large and irregular. In Dictyobia the tegmina are horizontal to body, approximately same length as body, but each tegmen undulates between depressions and inflated areas, while in Neaethus the tegmina are usually distinctly vertical, longer than the body and flat.

HISTORY OF THE GENUS

Uhler (1889) described the genus with the species permutata as the type species. In 1910 Dr. E. D. Ball described combinata, and in 1914 Doctor Van Duzee described atra. In the present paper one new species is being added, namely, Dictyobia varia.

Dictyobia permutata Uhler, 1889

Uhler, P. R. New Genera and Species of American Homoptera. Trans. Maryland Acad. of Sci. 1, p. 39, 1889.

Comparative notes. Uhler described the species from five females taken at Los Angeles, Cal., and for which he gave the size as being 5-6 mm. The writer had available for study one female specimen from the National Museum, collected by C. V. Riley at Los Angeles and two male specimens from Coquillet’s collection taken at Los Angeles, and the length of these was 4.4-4.5 mm. The males showed the distinguishing characteristic mentioned by Van Duzee and Uhler of the pale areoles being fewer in number, larger towards the apex, but the female specimen showed more numerous pale cells with greater uniformity, although at several spots these smaller cells tended to join together to produce the larger hyaline spots. Frons with median carina prominent, the disk yellowish-tan spotted with dark brown.

Male genitalia. The harpago in flattened lateral view is distin- eulshed by having a larger, more curved external hook than in other species as is seen in the drawings. The anal flap is approximately twice longer than wide and the eleventh segment bears a short stylus.

The aedeagal structure is distinctive. The basal fourth of the aedeagus is covered by the semimembranous theca which on the dorsal side extends caudad into a long, slender, sharply tapering flap which does not quite reach the apex of the aedeagus. The aedeagus is a sclerotized tube, bearing at approximate base of apical fourth a small spinelike process and near base, projecting beyond the pos- terior lateral margin of the theea, two sickle-shaped processes, of which the ventral one is a trifle the shortest.

Notes on distribution. Described by Uhler from specimens taken at Los Angeles, Cal. One additional specimen has been noted from Monrovia, Cal.

Dictyobia atra Van Duzee, 1914

Van Duzee, E. P. A Preliminary List of the Hemiptera of San Diego, Cal. Trans. of San Diego Soc. of Nat. Sci. 2 (1), p. 42.

Comparative notes. In the original description Mr. Van Duzee states that it is the size and form of permutata, presenting no really good structural characteristics, but that it may be distinguished by

S6 THe UNIVERSITY SCIENCE BULLETIN

its velvety black color, especially on the elytra. He gives the length as 4-5 mm., and points out that the elytra are closely reticulated with the pale vittae obscured by black veinlets and with none of the pale areoles materially larger as they are in permutata.

The differences noted above are the main distinguishing characters other than the male genitalia. The species of this genus are not easily separated.

Male genitalia. The anal flap seems comparatively shorter and broader than in permutata, its length being only one-third longer than its width. The eleventh segment is more conspicuous and bears a relatively longer stylus.

The harpago in flattened lateral view has its dorsal apical angle somewhat more produced and the external lateral hook is propor- tionally shorter.

The aedeagus differs from that of permutata by having the two curved basal hooks proportionally longer, by lacking the small sti- letto process at base of apical fourth and instead having a sharply pointed longer process at about middle of aedeagus.

Notes on distribution. Deseribed by Doctor Van Duzee from nu- merous examples taken on the chaparral from May to July at San Diego, Cal. Examples in the Snow Entomological Collection are from Idyllwild, San Jacinto Mountains, Big Bear Lake, Monrovia and Cajon, Cal.

Dictyobia combinata Ball, 1910

Ball, E. D. New Genera and Species of Issidae (Fulgoridae). Proe. Biol. Soc. Wash., XXIII, p. 43.

Comparative notes. Doctor Ball points out in the original deserip- tion that it is slightly longer than permutata with longer, less angled elytra. The author found the length of the female specimen studied to be 4.8 mm., and that the tegmina were over twice wider than long with the costal margin distinctly rounding. The vertex of this spe- cies is broader than in other species, six times wider than its median length.

Male genitalia. Only one female was available for study.

Notes on distribution. Described from five specimens taken at Colfax, Cal. The author had one specimen from San Jacinto Moun- tains, California.

Dictyobia varia n. sp. ORIGINAL DESCRIPTION

Size. Greatest length varies between 3.5 mm. and 4.2mm. Great- est width of tegmen 1.8 mm. This is the smallest species in the genus.

DoERING: THE SUBFAMILY ISSINAE 87

Color. General color lighter than in other species, being yellowish- tan marked with brownish-fuscous. Vertex fuscous except a median pale-yellow stripe and a thin pale border on all sides with, however, the carinalike edges brown. Eyes fuscous. Frons tan variegated with brown through disk, the brown marks becoming deeper just inside lateral margins where they set off circular vellow spots of varying sizes. Postelypeus light yellow, washed on each lateral disk with brown. Pronotum yellow, washed in fuscous, a light yellow median stripe and each lateral disk speckled with dark brown; meso- notum reddish-brown except extreme lateral corners, thin median line and posterior apex light yellow; venter at thorax light yellow. Abdomen light yellow near base, becoming reddish-brown toward apex, sometimes terga of 6th, 7th and 8th segments mottled with dark brown. Tegmina more variegated or speckled in appearance than other species; longitudinal veins, tannish-yellow, veinlets between dark brown in sharp contrast to the white areoles; the pale areoles forming a diagonal vitta from middle of clavus to the costa behind middle, somewhat constricted at middle, where it sends a branch to the inner apical angle so that a rough Y is marked off in the fuscous background, the fuscous areas mottled in fuscous and reddish-brown ; on the costal margin is a pale spot consisting of several round pale spots and another row of pale spots near apex just anterior to apical vein, the entire costal and apical margins bordered with white spots which are smaller and more circular at base, becoming fewer and larger toward apex so that the brown spots between are greater in diameter than the white ones. Legs mostly light brown, except pale at tips of coxae, femora and tarsi and a longitudinal stripe down length of femur, claws black-tipped.

Structural characteristics. Vertex narrower in this species, being only twice wider along anterior margin than one lateral margin and the anterior margin roundingly produced. Frons narrowed, with parallel sides and one lateral margin slightly more than one-fifth longer than the basal margin. Pronotum coneave through disk, a crescent-shaped carina elevated against vertex, behind eyes nar- rowed to a slender arm, becoming knoblike at extreme side, after which it expands into a platelike flap below eye on ventral side. Mesonotum with two diverging distinct lateral carinae. Tegmina not extending beyond abdomen, with position on body and undula- tions characteristic of genus, longitudinal veins distinctly elevated, cross nervures less so, reticulation finer even than in D. atra, espe- cially near base, cells less concave than in combinata or atra.

SS THe UNIVERSITY SCIENCE BULLETIN

Male genitalia. Anal flap parallel-sided, truncate at apex, not quite twice longer than wide. Eleventh segment distinctly visible with a prominent fingerlike stylus.

Each harpago from flattened lateral view is distinctive from other species In that the apical dorsal angle is much less extended dorsad into a shorter apical hook and externally bears a longer, recurved hooklike process.

The aedeagal structure also differs distinctly by having the two curved basal hooks which protrude beyond posterior margin of the theea, much broader basally and thus proportionally much thicker und shorter than in other species while the aedeagus itself is propor- tionally much shorter.

Comparative notes. This species is distinguished from other spe- cies externally by its more mottled coloring of the tegmina with the distinctive light longitudinal veins, its finer reticulation, less concave cells and its narrow vertex. The male genitalia differ as mentioned above.

Distribution and types. Described from one male holotype, one female allotype and 8 female and 7 male paratypes taken at Big Bear Lake, California, on July 26, 1932, by Dr. R. H. Beamer. These types are in the Snow Entomological Museum at the Univer- sity of Kansas.

The Genus Dictydea, 1888 HISTORY OF THE GENUS

This genus was erected by P. R. Uhler in 1888 for two species, angustata Uhler and intermedia Uhler. Both are taken in Cali- fornia. In 1938 Dr. E. P. Van Duzee described two additional spe- cies, variegata and falcata. In the present paper three new species are being added, namely D. valida, D. uhlert and D. niarata.

Comparative notes. This genus seems to be a transition between the genera Danepteryx and Dictyobia. Its distinguishing character- istics are a quadrangular vertex, depressed through disk, a hemi- spherical pronotum protruding forward between eyes with elevated anterior margins, becoming very abbreviated as a thin arm around eye, which again broadens into a flat, broad plate on side of head below and posterior to eye. Frons vertical to body, clypeus deflexed. Tegmina narrow, not usually so scimitar-shaped as in Danepteryz, although falcata and variegata approach this shape, much of the underside of body exposed below tegmina. Venation as follows: Vein Sc, close to costal margin, extending approximately halfway of tegmen; main longitudinal veins distinct, elevated, vein Sc, and R

The characters given in the above key are taken directly from the key in Professor Van Duzee’s paper (1938). The specimens of D. nigrata were compared by Doctor Beamer with the

specimens in Professor Van Duzee’s collection and found not to be the same.

Dictydea valida n. sp.

Size. One of the largest and most robust species in the genus. Length of female from apex of head to tip of tegmen, 5.2 mm. to 5.4 mim.; length of male, 4.8 mm. Greatest width of tegmen just back of claval apex, 1.7 mm.

Color. Color distinctive, having a general tan color marked with fuscous, whereas other species are piceous black. Upper body tan, marked with splashes of reddish-brown on disk of vertex, pronotum and mesonotum; a faint cream median line on vertex and pronotum, on each side of which, on pronotum, are two round, depressed spots. The thin carinate margins of frons, vertex, pronotum, dark brown. The carinae, lateral margins and apex of mesonotum lighter yellow tan. Frons golden tan with an irregular dark spot in center and numerous round, brown, depressed spots along each lateral margin. Clypeus golden tan with brown oblique bands on each lateral disk ef postelypeus and each lateral half of anteelypeus mostly dark.

9() Tue UNIVERSITY SCIENCE BULLETIN

Eyes reddish-brown. Thoracic segments yellowish-brown. Legs golden brown with darker streaks on femora, carinae of tibiae and tarsal claws blackish-brown. Abdominal segments mostly yellow tan, the first few segments marked with round, brown spots across disks of venter and sometimes the lateral posterior margins dark brown. Tegmina splotched in cream, light and dark fuscous as fol- lows: A large, irregular dark fuscous spot with base starting at apex of clavus and spreading over into corium; a smaller, dark spot in line with this on costal border from whence a lighter fuscous longitudinal band extends cephalad to base of tegmen; an indefinite brownish crescent across apex inside of membrane; these darker areas thus setting off an irregular light Y of creamy, semiopaque cells on each tegmen as viewed from the side; veins light yellowish-tan.

Structural details. Vertex deeply depressed across disk with lat- eral and anterior margins sharply carinate and elevated, its width along anterior margins three times greater than on lateral margins. Pronotum with anterior margin evenly, roundingly protruded be- tween eyes, each lateral part of this margin distinctly elevated, al- though not as much as in other species, disk depressed with a pair of round, sunken pits in middle. Mesonotum elevated up from sides, having a long anterior border through middle a deep crescent-shaped crease, on each side a lateral carina which extends from anterior bor- der to posterior border, a less pronounced median carina present and the extreme apex set off by a shallow, depressed transverse line. Frons slightly longer than wide, the lateral margins outwardly rounded and somewhat elevated, and a well-pronounced median carina present. Clypeus in length equal to anterior margin, angu- lately produced into frons. Tegmina distinctive in shape because of its more evenly rounded claval and apical margin, giving the wing a hemispherical shape and a much greater slope to the costal margin. Venation prominent, vein M branching considerably anterior to middle and Se, and R branching posterior to M.

Male genitalia. Anal flap rectangular in shape with posterior ventral margin of the tube truncately notched.

Each harpago from flattened lateral view rectangular with the ventral margin moderately curved outward and the dorsoventral! angle extended cephalad into a tapering hook with an external ven- trad curving process attached near this point.

The aedeagal structure is long and slender. The sleevelike theca does not quite cover half of the aedeagus on the lateral and ventral sides, is notched or split on the dorsal side, and then this dorsal part

DoERING: THE SUBFAMILY ISSINAE Q]

extends caudad as a partially sclerotized flap which is shghtly longer than the aedeagus itself.

The aedeagus is a sclerotized tube, bearing two sharply pointed hooks near the base, whose apices show beyond the caudal rim of the theea and a third, smaller, sharply pointed hook at about base of apical third.

Comparative notes. This species is readily distinguished from other species by the large, robust size, the hght colored, variegated tegmina, and the semispherical shape of the latter.

Notes on distribution. Described from male holotype and female allotype taken in the Giant Forest, California, July 28, 1929, by R. H. Beamer, two female paratypes same data, one female paratype and one male paratype from Maria county, California, August 3, 1929, by Paul Oman. These types are in the Snow Entomological Museum, University of Kansas.

Dictydea angustata Uhler, 1889

Uhler, P. R. New Genera and Species of American Homoptera. Transactions Maryland Academy of Sciences, Vol. I, p. 37, 1889.

Van Duzee, E. P. The Genus Dictydea Uhler (Homoptera, Issidae). Pan-Pacific Ento- mologist, Vol. XIV, No. 1, pp. 33-35.

Comparative notes. This is a piceous black species with no hyaline spots on the tegmina except along the border, and measuring about 5 mm. in length from tip of head to apex of tegmen for fe- male, and 4.5 mm. for male.

Uhler separates this species from intermedia by being less robust and with the wing covers not convex behind middle as in that species. Additional minor differences from other species noted by the writer are: The lateral margins of frons subparallel, venation of the teg- men tending to be that vein Se and R branch at apex of apical third, and vein M at tip of clavus.

Male genitalia. Anal tube and flap larger than in intermedia, each lateral margin convex and both converging to a truncate apex where the extreme caudal margin of flap is slightly concave. The eleventh segment is visible as a short, but distinct annulus, and bears an ex- tremely large stylus which is broad at base, then is bluntly pointed and almost reaches caudal margin of flap.

Each harpago in flattened lateral view is subrectangular in shape except for posterior dorsal angle which extends cephalad into a short, recurved hook and at base bears a blunt median hook on the inside and externally a much more sharply pointed hook which curves ventrad.

g2 THE UNIVERSITY SCIENCE BULLETIN

The aedeagal structure is similar to this process in intermedia. For a written description, see the discussion under the comparative notes for that species. A comparison of the drawings will show the differences in the two species. In the drawing of angustata the aedeagus has been raised slightly out of its normal position, so that the hooks point somewhat differently.

Notes on distribution. Uhler described the species from a pair taken at Los Angeles, Cal., by Coquillett. Additional specimens in the National Museum and Snow Entomological Collection have been taken at Saugus, Cajon and Mint Canyon, California.

Professor E. P. Van Duzee (1938) states that he has taken angus- tata in Mint Canyon, north of Saugus, California, and Dr. E. C. Van Dyke has taken at Lythe Creek, San Bernardino, California, a series of a form that does not seem to differ except in its larger size and darker color.

Dictydea nigrata n. sp. ORIGINAL DESCRIPTION

Size. Length of body from apex of head to tip of abdomen for female, 4.8 mm.; male, 4.6 mm. Length of tegmen, 4.4mm. Great- est width of tegmen, 1.73 mm. Width of pronotum, female, 1.75 mm.; male, 1.6 mm.

Color. Blackest species in the genus. Vertex, pronotum and meso- notum brown-black except for a faint, median, light streak, the ex- treme lateroposterior angles of vertex and apex of mesonotum yel- low. Eyes gray-brown. Frons dark brown, faintly mottled in light fuscous, clypeus yellow-brown, darker on extreme sides. Gena brown-black except the extreme lateral region back of eye and a spot below antennae. Antenna brown-black, except tip of pedicel and connecting conjunctivae of segments. Body segments brown-black mottled in lighter brown, connecting conjunctivae of legs white in sharp contrast to rest of dark body. Legs darkly infuscated except at the bases and apices of segments. Tegmina uniformly pitch brown except for sharply contrasting, semiopaque, white spots in the fol- lowing places: On clavus a series of roundish spots along inner mar- ein, a group of 3 to 4 spots across its middle, and another single spot toward apex, on corium round, rather uniform, spots scattered all around margin, one or two roundish spots located just anterior to base of apical third along costal margin, another one or two trans- versely in line with this, but lying between vein M,,, and Cu,.

Structural characteristics. Vertex somewhat narrower than im aungustata, its anterior margin being about two and one-half times as

DoERING: THE SUBFAMILY ISSINAE 93

wide as one lateral margin. Frons approximately as in angustata, although a trifle narrower as compared side by side, with its median carina sharp and appearing even more elevated than the lateral mar- eins. Pronotum much as in angustata, being four times wider than length at middle and the lateral arm behind eye elevated knoblike, after which it narrows again to surround eye before expanding into the characteristic flattened lobe on the extreme side of head. Teg- mina of the broader type, its length about two and three-fourths times its greatest width, which is at base of apical third. Longi- tudinal veins distinct, but not as much as in some species, cross veins also distinct. Vein Se, and R branching just before middle, vein M in line with apex of clavus, Cu, branching anterior to middle.

Male genitalia. Tenth abdominal segment extremely long, almost parallel-sided for two-thirds its length, then narrowing considerably to form the anal flap of which the apical margin is concave. Elev- enth segment ringlike, visible beyond the dorsal posterior rim of the tenth segment, on its ventral margin bearing a broad stylus.

Each harpago from a flattened, lateral view is rather L-shaped, the dorsal posterior third extended into a triangular projection, at base of which on inside is a broad, pointed hook, another external to this with a shghtly recurved apex.

The aedeagus is a long, slender, gooseneck tube covered on basa! third by the more sclerotized, sleevelike theca. The dorsal part of the latter is extended caudad as a pointed flap which does not quite reach to apex of aedeagus. No sclerotized hooks of the aedeagus are visible, but one is visible through the wall of the theca.

Comparative notes. This is one of the broader-winged species in the group, each tegmen at its greatest width being about two and three-fourths times longer than wide, while in angustata it is about two and one-half times longer than wide. In color it resembles D. falcata Van Duzee, but is separated from that species by the much broader tegmina.

Notes on distribution and types. Described from two specimens, holotype male and allotype female, taken at San Antonio Canyons, California, on August 4, 1938, by R. H. Beamer. Types are in the Snow Entomological Museum at the University of Kansas.

Dictydea intermedia Uhler, 1889

Uhler, P. R. New Genera and Species of American Homoptera. Transactions Maryland Academy of Sciences, Vol. I, p. 38, 1889.

Van Duzes, E. P. The Genus Dictydea Uhler (Homoptera, Issidae). Pan-Pacific Ento- mologist, Vol. XIV, No. 1, pp. 33-35.

Comparative notes. This species was described from three fe- males, of which the length was given as 5-6 mm., and the width across pronotum as 1.75mm. The length of the males is around 4 to 4.6 mm., and the width of pronotum 1.6 mm.

The main distinguishing features of this species are that the lateral margins of frons are slightly convergent; the costal margin of tegmen is slightly convex behind tip of clavus; the vein Se, and R usually branches at middle and M at middle or slightly posterior and the color pattern of tegmen is as follows: Ground color black piceous, with a large hyaline triangular spot spreading across the clavus upon the adjoining cells of corium, a band of the same color transversely crosses the corium behind tip of clavus, a similarly colored spot curves near the apex and the flattened border all around the wing cover is interruptedly brown and hyaline.

Male genitalia. Anal flap elongate, the ventral margin expanded only one-third of the total length, at apex only slightly concave. The eleventh segment is not visible except for fingerlike stylus.

Each harpago in flattened lateral view narrowed at base, greatly expanded across apex, its apical dorsal region extended into a slender. shghtly cephalad curving hook, bearing just back of middle along dorsal margin two short hooks, a much shorter stout inner one and a slightly longer external one which curves downward and slightly cephalad.

The aedeagal structure is asymmetrical. From the left side the theea covers the basal third of the aedeagus like a membranous sleeve, then splits along the side, the ventral part then forming a bluntly pointed flap reaching only halfway of the total structure, the dorsal part extended caudad into a long, sharply pointed flap which is as long as the aedeagus itself. The exposed part of aedeagus between the split theea is tubular, ending in a sharply pointed spine and bearing in ail four sclerotized processes, two located on the left side at the place where the theca is notched, and a small one near tip. On the right side is a larger, recurved process attached approxi- mately at middle and extending to base of apical third of aedeagus.

Notes on distribution. Uhler gives the type locality as Los An- veles, California. The writer had a few specimens for study from

DoERING: THE SUBFAMILY ISSINAE 95

the following places in California: Saugus, Mint Canyon, Big Bear Lake and Cajon.

Professor E. P. Van Duzee (1988) states that this species is a common species in Mint Canyon on the holly-leaved cherry, Prunus illicifolia.

Tegmina uniform fuscous brown except for the entire border, which is yellowish-white crossed by numerous dark veinlets or broader dark bands, a small white spot on corium just inside of apex of clavus, a larger triangular area of several semiopaque white cells on corium just posterior to apex of clavus.

Structural details. This is a small, narrow-winged species. Ver- tex narrower than in several species, its anterior margin only twice wider than one lateral margin or four times its length through mid- dle. Frons narrow, lateral margin one-third longer than its basal or posterior margin, its length through middle equal to length of elyp- eus, median carina sharp and complete for length of frons, the two lateral margins more or less parallel and greatly elevated. Pronotum roundingly produced between the eyes, not quite to the anterior mar- zin of eye, the margins moderately elevated, behind eve reduced to a characteristically narrow rim. Mesonotum depressed considerably through middle, so that lateral areas and apical third are elevated

96 THE UNIvErsITY SCIENCE BULLETIN somewhat kneblike. Tegmina narrow, being about three and one- half times longer than greatest width, which is at base of apical! third, not much slope to the costal margin of tegmen in situ since the latter and claval margins are subparallel. Longitudinal veins, thick and conspicuous, branching as follows: Vein Se and R branching posterior to middle and vein M considerably anterior to middle. Comparative notes. This species is easily distinguished structur- ally from other species by the width of the tegmina, being not as narrow as falcata and variegata nor as wide as the remaining species. It has a narrower vertex proportionally than the majority, has the pronotum much more reduced behind eyes, and a more elongate frons. In color the species is differentiated by the color pattern of the tegmina as can be noted by reading the descriptions of these structures for the various species or by looking at the drawings. Notes on distribution. This species was described from one male specimen in the National Museum collection, designated P. R. Uhler collection on a printed label, above which is an ink label, bearing an illegible abbreviation Los Ang., which the writer has interpreted to be Los Angeles. No date is given for the specimen.

Ball, E. D. New Genera and Species of Issidae. Proc. Biol. Soc. of Washington XXIII, pp. 41-46.

Comparative notes. The distinctive features of this genus are the ovate, abbreviated tegmina, the elevated and triangularly extended, anterior margin and deeply concave disk of the vertex, the strongly inflated clypeus, tricarinate mesonotum, very rudimentary wings and posterior tibiae with one or two spines.

Wing venation. The venation in this genus is reduced. Vein Se, is not distinct. Veins Se,, R, M, and Cu, are all single veins arising from the usual basal cell. Vein Cu, is found in the claval suture. First and second A united at tip to form the usual y. The rest of the tegmen is traversed by an irregular network of fainter veins.

Osbornia cornuta Ball, 1910

Ball, E. D. New Genera and Species of Issidae. Proc. Biol. Soc. of Washington XXIII, pp. 41-46.

Comparative notes. The distinctive features of this species are the acute outer angles of the vertex which are extended earlike above the eyes; the much abbreviated tegmina which are not much longer than broad, and roundingly truncate at apex, expose at least half the abdominal segments and are usually slightly separated by the elevated abdomen; the somewhat compressed abdomen, most seg- ments of which have distinct tuberculate median elevations.

The general body color of cornuta is dark brown, speckled and banded with light or reddish-yellow and for the tegmina light with veins and splotches darker.

This species when captured has very frequently already lost its wings or very soon does so after being taken in the net. For this reason many specimens in collections are wingless.

Male genitalia. Anal flap (10th abdominal segment) broad, parallel-margined for two-thirds its length, then tapering to a trun- cate apex. Eleventh segment typically reduced, bearing a long, slender genital stylus.

Harpagones (genital styli of authors) visible externally as two, long, tapering plates, whose inner margins are adjoined, and very little of abdomen showing beyond their apices. Each harpago as viewed from a flattened lateral view is rectangular and has its ex- treme dorsocaudal angle prolonged cephalad into a sharply pointed, recurved hook at the base of which is a flat, triangular, external hook. (See drawing 3a, plate XV.)

The aedeagus is asymmetrical. From the left side it appears as a long, slender, roundingly curved tube, partially membranous, bear- ing at apical seventh a long caudad-projecting spine and near its base a pointed, heavily sclerotized hook, which shows only halfway beyond the thecal margin. On the right side the aedeagus shows an external, slender, pointed hook attached just slightly caudad of middle. The theca is membranous and therefore difficult to trace. It covers the basal fourth of the aedeagus as a tube, then on the left side has its caudal margin somewhat broadly notched through upper middle to allow the aedeagal hook to show, its margin ventrad of the notch prolonged caudad into a slenderly tapering, curved process and dorsad of notch as a short, blunt process. On the right side the ventrocaudal angle of the theca projects caudad as slightly

t

curved, pointed process, whose apex reaches to a point midway of the length of the aedeagus.

Notes on distribution. Doctor Ball described the species from 12 examples taken at St. George, Utah and Mojave, California. A large series is found in the Snow Entomological Collection, Uni- versity of Kansas, collected by Dr. R. H. Beamer, from Mojave and Palmdale, California, in July, and two specimens from El Paso county, Texas, in July.

Osbornia arborea Ball, 1935

Ball, E. D. Some New Issidae with Notes on Others. Bull. Brook. Ent. Soc. XXX, p. 38.

Comparative notes. Resembling cornuta Ball in size and general body form. It differs from cornuta by not having the prolonged angles of vertex above the eyes, by its anterior margin of vertex triangularly produced cephalad, and by having much longer tegmina which in this species cover all but the last two or three apical seg- ments of the abdomen, but in cornuta only the first two or three basal ones.

Other easily recognized characteristics are the uniform yellow and green color and the transverse depression through middle of tegmina.

Male genitalia. Anal flap (10th abdominal segment) a broad parallel-margined flap which tapers to a slightly emarginate, trun- cate apex. Eleventh segment not easily visible externally, bearing a short genital stylus.

Harpagones (genital styli of authors) visible externally as two pointed, slender plates, whose length is about three and one-half times their width. Each harpago as viewed from a flattened lateral view appears pear-shaped, but with its dorsocaudal angle prolonged dorsad as a broad, flat extension which is roundingly emarginate at its apex. At the base of this extension is a triangular, flat, external hook whose apex is directed ventrad.

The aedeagus in this species is a curved semisclerotized tube with more of a bend in it than in cornuta. It is asymmetrical. On the left side it bears a short, thick, spinelike process near its apex and two others attached near base, the dorsal one of which is the longer, broader as it emerges from the theca and at the end forming a slender curved hook, both hooks covered at base by the theca. On the right side it is spineless. The theca is a semimembranous tube embracing about one-half of the aedeagus at base and which on the right side is truncate at its posterior end. On the left side the theca splits along the ventral side, allowing the aedeagus to emerge be- tween the folds.

Notes on distribution. Doctor Ball described the species from about fifteen specimens taken at Patagonia, Arizona, on juniper. In the Snow Entomological Collection at the University of Kansas is a large series taken by R. H. Beamer in July and August at Red Lake, Santa Rita Mountains, Coconimo county and Oak Creek Canyon in Arizona, and several specimens from Tucumcari, New Mexico. Mr. E. W. Davis took two specimens from St. George, Utah in August.

Osborna arborea var. fusca

In its extreme color phase this variety is entirely fuscous bordered with black. Vertex smoky brown, except a median line and lateral margins creamy yellow to green. Eyes gray, washed in brown. Frons uniform fuscous except each laterobasal corner and a longer spot on each apical-lateral corner which is light yellow to green and a vertical row of small, dark, brown dots, usually in pairs extend- ing the full length of the disk on each side of the lateral carinae. Clypeus light brown except dark, oblique lines across disk, a spot at the basolateral angle and the extreme lateral margin light. Labrum fuscous. Genae around eyes fuscous, below antennae green- ish-yellow. Antennae fuscous. Pronotum from above dark fuscous except for a light spot back of eye in which are found a number of very round, uniform-sized brown dots, pleural flaps of pronotum greenish-yellow through middle, anterior and ventral margins brown- ish. Mesonotum dark brown, with a faint, ight band indicated on each side and the extreme apex light. Tegmina shining brown to almost black, except for somewhat fainter indistinct spots at wing base, a transverse band just anterior to middle, and a roundish spot across apical dorsal cells. Dorsum of abdomen dark brown except for median lighter band, a broader one under the tegmina. Venters of thorax and abdomen blackish-brown, the pleural sclerites hght green in sharp contrast. External genitalia of male brown with margins lighter. Female lighter than male. Tegmen yellow with clavus bordered in black, black splotches across middle of corium and apical margins black, a broad band of light across abdominal venters and most of ovipositor valves yellow, edged in black.

Some specimens of true arborea approach in color the females of fusca by having faint touches of dark on pronotum and border of corium. These, however, usually lack a spot across middle of corium and the black is not so pronounced.

Comparative notes. Head broad, the vertex approximately six times wider than its greatest length, the frons extended forward, sloping, from above triangular, bearing a less pronounced median carina, usually two well-pronounced lateral carinae which form an ovate or top-shaped central tablet between, the extreme lateral margins of frons elevated carina-like forming a sharp shelf over the genae. Postelypeus elongated, extended forward and parallel to body, together with the extended frons making up the so-called frontal process. Pronotum with anterior margin roundingly pro- duced between eyes, posterior margin only shallowly emarginate, at sides behind eyes so greatly reduced as to be practically hidden by eyes, then again expanding platelike at sides, around eyes and posterior to gena so that each gena is a deep pocket in which are located the antennae. Mesonotum is broad, triangular, with a me- dian carina and two lateral, slightly converging carinae usually indicated. Tegmina usually brachyterous, occasionally macropter- ous forms in some species, snugly fitting but not covering abdomen, parallel at sides, cut off straight behind with the terminal corners rounded, parchmentlike, thickly reticulate venation. Hind wings of macropterous forms present and large although shorter than tegmina; entirely lacking in brachypterous forms. Abdomen globose, nar- rowed behind into a blunt tip. Legs short, hind tibiae with one spine.

Macropterous forms

Long-winged individuals have been found in collections for five species in this genus. In these five they are very rare. In a series of several hundred specimens of B. oculata two specimens only were found, in a large series of B. keidensia only one, and only one

DorERING: THE SUBFAMILY ISSINAE 101

each in B. nodosa and B. pallidipes. The writer did not have any specimens of B. vittata for study.

In all cases the nasal process and general coloring of body were identical in both brachyterous and macropterous forms, so that the species can be identified in the usual ways. In addition there seems to be specific differences in the color of the wings and slightly in the venation. B. oculata and B. keidensia both have fuscous front and hind wings, with very heavy dark-brown veins. The former tends to have a tendency of the veins of front wing, branching more than in keidensia although since the two wings of the same individual were different this cannot be relied upon as a distinguishing char- acteristic.

B. pallidipes had pale-colored wings, with less heavy, light-yellow veins. B. nodosa had fuscous or dark brown front wings and milky white hind wings with brown veins. This specimen was broken too badly to draw.

The venation of B. oculata, B. keidensia, and B. pallidipes is shown in the figures on plate X XI.

HISTORY OF THE GENUS

Newman described the genus and the species oculata in 1838. Fitch, in 1856, described dorsata. Stal, in 1862, described the fol- lowing five species jocosa, pallidipes, tristis, nasuta and flavo-vittata. Through the courtesy of Mr. China of the British Museum and Doctor Lundblad of the Stockholm Museum, it seems quite certain that nasuta is a synonym of oculata Newman and, agreeing with Doctor Ball’s opinion, the writer believes flavo-vittata to be a synonym of dorsata Fitch. In 1906 Melichar added sutwralis, in 1907 Kirkaldy added mormo. This brought the genus down to the year 1923 when the first extensive account of the genus was made by Metcalf. In the Fulgoridae of Eastern United States Metcalf gives a key to twelve species of Bruchomorpha, five of which he describes as new. These five were vittata, bicolor, minima, rugosa and decorata. Doctor Ball and the present writer believe that bicolor is a synonym of vittata. In 1928, in his paper entitled the “Fulgoridae of Mississippi,’ Dozier gives a key to eleven species of which one, bimaculata, is described as new. Again this species has been placed in synonymy with jocosa by Doctor Ball and the present writer. In 1935 Dr. E. D. Ball published a revision of the genus. In his key and notes he lists eleven species, of which triunata is described as new. In addition to the synonymy given above he places minima Metcalf as a synonym of mormo Kirkaldy,

102 THe UnNIversiry ScieNcE BULLETIN

nasuta Stal as a color variety of oculata Newman, and he describes two new color varieties of jocosa Stal and three new color varieties of oculata Newman, two of which, namely abrwpta and extensa the present writer believes to be good species. The present writer, after many years of study of the genus, believes in the validity of four- teen older species, to which is being added six new species, making a total of twenty species in the U. 8S. North of Mexico at the present time known to collections.

AUTHOR’S DESCRIPTION

Size. Length of body from apex of head to tip of abdomen, 1.8 mm. to 2.5mm. Greatest width of body, 1mm. to1.4mm. Length of tegmen, 1 mm. to 1.2 mm.

Color. General color pitch brown with a conspicuous dorsal con- trasting pale-yellow stripe; this stripe narrowed at apex of frons, on vertex about one-third of total width, the same width on thorax as on vertex, again narrowing to half this wide on the combined claval margins. The abdomen pitch brown, occasionally with a faint indication of yellow on first abdominal segment, under side of body pitch brown except less sclerotized areas of thorax and sometimes the clypeus. Legs, especially of females, dark brown, sometimes yellow on apical half of coxae and basal half of tibiae.

Structural details. One of the short-nosed species in the genus with the frons extended cephalad a distance equal to length of one eye. A median carina present on frons, but less distinct than in some species; two outwardly curving lateral carinae which meet the median carina just posterior to apex; a series of round pits pres- ent between the lateral carinae and eyes, a row of eight just laterad of each lateral carina and a row of four against the eye. The frontal suture raised on a slight carina which is not so shelflike as in ocu- lata. The antennae, therefore, not in such a deep pocket as in that species. The ventral margin of the postelypeus straight, its length as measured from anteclypeus to apex approximately equalling width of frontal process at its apex. Vertex short, about six times wider than long, transversely concave and with a median carina. Pronotum characteristic of the genus, practically covered at sides by the eye, arched forward between eyes for a distance about two- thirds length of eye, the median carina less distinct than in some species, each lateral dorsal third covered by approximately twenty- four round pits; the extreme sides of pronotum extended below eye

into the characteristic flap which in this species is distinctly angu- late on ventral margin and bears two rows of circular pits. Meso- notum conspicuous, not as broad as in some species, less than twice wider than long, the median carina less distinct, two sharp laterally convex, lateral carinae present, laterad of which are numerous round pits, numbering between 14 and 20. Tegmina rugulose, a few longitudinal veins elevated more distinctly above the network, in length extending about three-fifths of the length of the abdomen. About four abdominal segments visible from above, a distinct carinae on lateral side of each segment just back of posterior mar- gin, closely followed by two rows of circular pits.

Male genitalia. Tenth abdominal segment (anal flap) tubular at base, then with posterior ventral margin extended into a roundingly pointed flap, which is slightly longer than the basal tube. A small portion only of the eleventh segment visible beyond the dorsal mar- ein and bearing a short, pointed flap.

Each harpago, as viewed from a flattened lateral view, a rectangu- lar plate with its basal fifth prolonged cephalad into a slender pointed handle and its apical two-fifths greatly prolonged as a sharply pointed process which curves directly cephalad.

The bilaterally symmetrical aedeagal process is characteristic for the genus. The theca covers the aedeagus through the middle as a snugly fitting membranous sleeve narrowed at base and with its ventral median region extended caudad as two truncate flat lobes which curve slightly cephalad, leaving a notch on each side from which protrudes a sharply pointed, well-sclerotized aedeagal process. The well-sclerotized aedeagus is hidden except at base and for this process mentioned above.

Comparative notes. This species resembles B. minima Metcalf and B. beamerin. sp. It is easily separated from either by its snub- nosed appearance, which is due to the frontal process being distinctly elevated at tip and by having the ventral margin of postelypeus straight. From B. minima it is furthermore separated by the median yellow stripe while minima is an entirely black species. From B. beameri it is separated in color by having black or darkish legs, while the latter has yellow legs.

Because of its black legs it might easily be confused with B. bunni and B. tenebrosa. For comparison with those species see notes under the descriptions of these species.

Notes on distribution. Melichar lists Colorado and Texas as the type localities. Dozier cites records of specimens taken in North

Bruchomorpha beameri n. sp.

ORIGINAL DESCRIPTION™

Size. A medium sized species with a medium length nasal process. Length of body from apex of head to tip of abdomen, 2.4 mm. to 3.3 mm. Greatest width across abdomen, 1.6 mm.

Color. General color metallic black. A conspicuous, cream- colored median stripe extending across frons, thorax and to tip of tegmina on which it tends to fade out at apex. Legs of male yellow except for last segment of tarsi and tips of spines. Legs of female vellow with basal half of coxae washed in fuscous, and femora and tibiae striped on each side with reddish-brown.

Structural details. This species has a medium-length nasal exten- sion. From above the frons extends a distance slightly greater than length of eye in male and about one and one-half times in female. A median carina is distinct on frons, pronotum and mesonotum. Frontal suture less elevated and antennae not so depressed in a socket as in other species. Ventral margin of postclypeus concave, its length as measured from anteclypeus to apex only slightly greater than width of frontal process at a point in line with the joining of lateral frontal carinae. The elevated lateral boundaries of head above eye not so shelflike as in oculata. Vertex broad, about eight times wider than median length. Median carina of pronotum distinct, pits in each lateral third indistinct, numbering approximately 19, at sides pronotum entirely superimposed by eye, below which it broadens into a slightly angulate flap which extends forward as far as antennae and anterior border of eye. Mesonotum with a median and two lateral carinae well pronounced, each lateral third bearing about twelve round pits. Tegmina rugulose, scarcely any longitudinal veins distinct.

Male genitalia. Tenth abdominal segment (anal flap) tubular at base, then with posterior ventral margin extended into a round- ingly pointed flap which is about twice longer than the tubular base. A tubular part of the eleventh segment only visible beyond the dorsal posterior margin of the tube.

DOERING: THE SUBFAMILY ISSINAE 107

Each harpago as viewed from a flattened lateral view semicircular in outline, very broad through middle, and with its apical dorsal angle extended into a sharply pointed process which is more slender and shorter than in suturalis.

The bilaterally symmetrical aedeagal process is characteristic for the genus. The theca covers the aedeagus through the middle as a snugly fitting membranous sleeve somewhat narrowed at base and with the ventral median margin extended caudad as two truncate flat lobes, each of which is as long as the tubular sleeve of the theca. Between the lateral notch of the thecal process is visible a sclerotized, slender aedeagal process.

Comparative notes. Superficially this species resembles the B. dorsata Fitch group, but is separated from that group, which is a short-nosed group, by its longer nasal process. For comparison with B. suturalis Mel., which it closely resembles, see the notes under this heading in the description of that species.

Comparative notes. In the original description Metcalf states that this species may be recognized by its shortly produced nasal process and elongate frons. The writer considers that this is slightly misleading in that the nasal process, although not as long as the oculata group, is much longer than the short-nosed group repre- sented by dorsata. The frons itself is not so greatly lengthened,

being only slightly longer than the length of the eye as viewed froin

above, but the postclypeus is very elongate, its ventral margin be- ing slightly over twice the length of either the anteclypeus or the width of the nasal process at apex. A distinctive feature of this species is the much narrowed nasal process which is distinctly trun- cate and not rounded at apex as in oculata. Other structural dis- tinctions are the less elevated frontal sutures so that the genae are proportionally broader and not deeply sunken, the longer vertex, which is only four times wider than greatest length and through middle twice as long as at sides, due to the lateral fourths of the anterior margin sharply bending caudad, the lack of any well-pro-: nounced median carina on frons and thorax, two lateral carinae present on mesonotum, the tegmina smoother with less reticulation of veins showing than in most species, a faint median carina present on each anterior abdominal segment.

Coloring distinctive, being a striped species with ground color yellow and two narrow brown stripes running lengthwise of body.

Notes on distribution. Type locality is Brownsville, Tex. Doctor Metcalf sent a paratype female to the writer for study, which bore the label “palm jungle sweepings.” In addition the writer had eight specimens in all for study, of which seven were from Brownsville and one from Progress, Tex. Apparently this is an exceedingly rare species.

Notes on synonymy. Metcalf described B. vittata only from macropterous forms. These were taken at the same time and place as B. bicolor Metcalf. Since macropterous forms are comparatively scarce in either species, it is difficult to get comparisons on this species. Doctor Ball states that, “All long winged forms have prac- tically the same dark color, and that they all have much enlarged mesonotal protuberances and consequently notched pronotums. The form of the nasal process is, however, distinctive.” He therefore be- lieves that B. vittata and B. bicolor are long and short-winged forms of the same species and that since vittata was listed first, the species becomes vittata with bicolor thrown into synonymy.

In support of this idea is the fact that they were taken together and that in the original descriptions Metcalf states that they have elongate fronts, and shortly produced truncate nasal processes. In comparing macropterous forms of other species the writer has found that the shape of the nasal process and coloring always follows closely that of the brachypterous forms. The situation became com- plicated by the fact that Doctor Metcalf sent the writer a brachyp- terous female specimen of vittata (hitherto only described from ma-

DoERING: THE SUBFAMILY ISSINAE 109

cropterous forms) which bears the label Medicine Hat, July, Alta. 24, F. S. Carr. This specimen evidently was subsequently deter- mined by Doctor Metcalf as this species. It is entirely different in coloring and body structures from a type specimen of bicolor. Since it is a moderately long-nosed specimen, the present writer identifies this specimen as B. beameri n.sp. The original descriptions of Metealf’s two species are given below.

Bruchomorpha nodosa n. sp. ORIGINAL DESCRIPTION™®

Size. Larger than B. oculata New. Length of body from apex of head to tip of abdomen, 3.29 mm.; width across abdomen, 1.48 mm.

Color. Black with a metallic luster, head and thorax lighter, somewhat reddish-brown. A rusty-yellow stripe following median carina from tip of frons, across vertex to margin of mesonotum. Tip of nasal process black, rest of head at sides and below reddish- brown in sharp contrast to black body; anteclypeus and beak tan. Legs yellow and rusty-brown streaked.

Structural details. This species is characterized by the excep- tionally long nasal process which is unusually inflated through apical region, giving it a knoblike appearance, and by the arched dorsal outline of body with the nasal process greatly deflected. As viewed from above the nasal process extends beyond eyes twice the length of the eye, approximately halfway of frons, being deeply de- pressed, and lateral margins conspicuously constricted, making the frontal plate violin-shaped and lateral carinae converging con- siderably before apex and about base of apical fifth. Median carina of frons through depressed area indistinct; carinae of pronotum and mesonotum distinct. Frontal suture less elevated, antennae not inserted in a particularly deep pocket. Ventral margin of post- clypeus deeply concave, to length as measured from anteclypeus to apex approximately twice the width of frontal process at a point in line with the joining of the lateral frontal carinae above.

and abdomen evenly humped through middle, nasal process and tip of abdomen distinctly deflected, giving the body as viewed from the side a more pronounced, half-moon shape than in other species.

Comparative notes. Similar to B. oculata New., but differentiated by the elongate, inflated and greatly deflected nasal process, which is conspicuously depressed across middorsal region, and with the lateral carinae of frons meeting considerably caudad of apex of nasal process. Usually easily recognized, in addition, by the con- spicuous red coloring on the ventral head region.

Bruchomorpha rosea n. sp.

Size. Length of body from tip of head to apex of abdomen, 2 mm. to 3.2 mm. Greatest width of body as viewed from above, 1mm. to1.mm. Length of tegmen, 1 mm. to 1.2 mm.

Color. A reddish-tan species becoming darker at the sides, in general color closely resembling jocosa. Frons reddish-tan, lateral margins and carinae dark brown, an indefinite yellowish median streak which extends across the thorax where it widens somewhat. Underside of head reddish-brown with extreme tip of nasal process black. Eyes dark brown or black. Thorax from above reddish- brown, washed in fuscous at sides. Tegmina uniform reddish-brown except mesal margins fading to yellow. Abdominal segments tan- nish to reddish-brown with posterior margins edged in dark brown. Legs amber yellow.

Structural characteristics. A long-nosed species with head pro- duced beyond eye, as viewed from above twice the length of the

113 THe UNIVERSITY SCIENCE BULLETIN

eye. Frons centrally compressed through the middle, a median carina slightly indicated, two distinct lateral carinae which dis- tinctly bend inwardly at middle. Nasal process as viewed from the side long; postclypeus three-fourths to twice the width of the proc- ess at a point in line with apex of frons, its ventral margin moder- ately concave. Pronotum from above short, its median length about two-thirds the length of the eye, laterally reduced behind eyes to a thin margin, then on sides broadening into spatulate earlike lobes which cireumscribe the eyes; on each lateral dorsal disk sixteen or seventeen circular pits. Mesonotum large, about twice as wide as long, a median carina present and on each lateral disk about twelve circular pits present. The characteristically abbreviated tegmina shining semitranslucent, wing venation very obscure, giving only a pebbled appearance. Abdomen globose, about four segments visible from above; on the segments which are exposed a lateral carina indicated just posterior to anterior margin of segment; usually four round pits present just posterior to the carina.

Male genitalia. Tenth abdominal segment (anal flap) with a short, tubular base which is about one-fourth of the total length of the process. The posterior ventral margin of the tube is expanded caudad into a roundingly pointed flap. The eleventh segment is ringlike and is scarcely visible beyond the dorsal posterior margin of the tube and bears a short dorsal stylus.

Each harpago, as viewed from a flattened lateral view, is some- what crescent-shaped, broadest through approximate middle, with its basal part arm-shaped and its apical third greatly lengthened and projected dorsad as a sharply pointed, slightly recurved hook.

The aedeagus is nearly hidden by the less sclerotized theca, the latter fitting over the aedeagus through the middle as a tight sleeve which broadens apically and also has its ventral apical margin ex- panded caudad as two rounded flaps which bend somewhat dorsad, thus leaving a notch on each side, from which protrudes a pointed, slender, well-sclerotized aedeagal hook. ;

Comparative notes. Size and coloring of jocosa Stal, but easily recognized by its long nasal process as opposed to the very short one of jocosa. It is easily distinguished from all other species in the genus by its rosy coloring.

REVISED DESCRIPTION

Size. Length of body from tip of head to apex of abdomen, 1.8

mm. to 3mm. Greatest width of body as viewed from above, .92 mm.to 1.4mm. Length of tegmen, .9 mm. to 1.2 mm.

Color. A shiny, metallic, black species usually marked with rust. Frons as viewed from above blackish-brown except for a yellow to rust median stripe which borders the brown median carina; this same band and carina continued across vertex and pronotum. Eyes pitch brown, margined in rust. Clypeal region and posterior part of gena reddish-yellow in female; in male same pitch brown as rest. of head. Thorax from above reddish-brown except for median light stripe and a faint lighter spot on pronotum behind each eye; lateral sclerites of thorax uniform black brown; membranous ventral parts yellow. Tegmina blackish-brown with a metallic lustre and a faintly lighter claval margin. Legs yellow to reddish-brown, washed in dark, especially near the base of each segment or in the form of dark, longitudinal bands. Abdomen from beneath pitch brown.

Structural characteristics. One of the moderately long-nosed species in the genus. As viewed from above the frons is produced anteriorly one and one-half to twice the length of the eye, its frontal tablet about two-thirds longer than its greatest width and a dis- tinct median carina present laterad of which on each is a slightly less prominent, outwardly curving carina, frequently interrupted or at least constricted halfway from the apex at which place the frons is depressed; the frontal sutures forming the lateral boundaries of the head as viewed from above are elevated on a conspicuous carina

which extends shelflike over the gena, thus forming a pocket in which lies the antenna. The ventral margin of postclypeus is dis- tinctly concave, its length at this point not quite twice the width of the nasal process just anterior to apex of frons. The labrum is abbreviated to a tiny triangular sclerite. Pronotum from above short, its median length about two-thirds the length of the eye, laterally so reduced behind the eyes that the posterior margin only shows at this point; each lateral disk with 16 round pits; on the extreme sides expanded into broad plates which curve around the eyes and end at the bases of the antennae and on each lateral plate a row of four circular pits following the posterior margin. Mesono- tum large, about twice as wide as long, on each side bearing nine round pits, a thin median carina present. Tegmina abbreviated, extending only slightly beyond middle of abdomen. Venation ob- scure, the whole surface of the tegmen roughened by the indistinct veins, giving it a pebbled appearance. Abdomen globose, only about four segments showing from above; on the first few segments a lateral carina indicated just posterior to anterior margin of segment; usually three to four pits present just posterior to the carina.

Male genitalia. Tenth abdominal segment with ventral margin extended into a roundingly pointed flap, its length about one-fifth longer than wide. Eleventh abdominal segment typically ringlike, only showing a slight distance beyond dorsal margin of the tenth segment and bearing a long fingerlike stylus.

Each harpago, as viewed from a flattened lateral view, Saba crescent-shaped, its basal fourth slenderly pointed, the median region with ventral margin greatly expanded, the apical fourth curving dorsad as a slenderly pointed elongate hook.

The bilaterally symmetrical aedeagal process is difficult to follow due to its minute size and the fact that it is covered so completely by the theca. The theca covers the aedeagus through the middle as a snugly fitting, membranous sleeve whose ventral margin is ex- tended caudad into two flat, spatulate processes about equal in length to the basal collar and having their roundingly pointed apices directed dorsad. The sclerotized tubular aedeagus is only visible between the collar and the lobes of the theca. At this point can be seen the bases of a sclerotized hook which is directed cephalad under the thecal collar and ends just inside the basal mar- gin of the theca.

Synonymy. In the literature two species of Bruchomorpha from northeastern and central United States have always been listed in keys, namely B. oculata and B. nasuta. With large series of speci-

DOoERING: THE SUBFAMILY ISSINAE iB)

mens it was always difficult to try to distinguish these two species. Therefore, the writer endeavored to clear up this situation by studying the types. Through the efforts of Dr. H. B. Hungerford, Doctor Lundblad, of the Stockholm Museum, kindly sent the type of B. nasuta Stal for study. This proved to be the form which has usually been identified as B. oculata Newman. The writer sent a close homotype of B.nasuta Stal to Mr.China of the British Museum, hoping that he would be able to compare it with the oculata type. After studying the question Mr. China sent the following reply to the author:

“The type of Bruchomorpha oculata has been lost. It is not in our collec- tion here nor at Oxford. According to Newman it was originally in the col- lection of the Entomological Club, but this collection was presented to the British Museum in 1844, so that the type should be here. I have been unable to trace it, however. We have under this name a single specimen labeled Bruchomorpha oculata, but it does not agree with the original description of oculata and was collected by E. Doubleday at St. Johns Bluff, East Florida, instead of by Foster at Mount Pleasant, in Ohio, as was Newman’s specimen. Your specimen labeled B. nasuta agrees very well indeed with Newman’s description and figures. The lateral carina of frons is pinched in and the ventral margin of the postclypeus is strongly concave. He describes the colour as ‘shining greenish bronzy-black,’ which would cover the metallic bluish black of your specimen since the green and blue metallic colours are inter- changeable. Bronzy in this description really refers to the metallic sheen and not to the brown colour of bronze. I should not hesitate in identifying your B. nasuta as oculata Newman.”

The writer believes, as does Mr. China, that Stal’s nasuta is a synonym of B. oculata, and many difficulties can be cleared up with this solution. Metecalf’s (1923) drawing of B. nasuta is correct for this species. It is not plain what his B. oculata is. Dozier’s de- scription of B. oculata is correct for this species. No specimens have shown up for his B. nasuta Stal as a distinct thing from B. oculata.

Comparative notes. This species resembles B. nodosa n. sp., B. minima Metcalf and B. abrupta Ball more than other species in the genus. For comparison with nodosa see the notes under this head- ing in the description of that species. From minima it is easily separated by having light colored legs instead of black ones as in minima.

For comparison with abrupta see notes in the description of that species.

Notes on distribution. Dozier (1926) states that this is the most common species of the United States, being widely distributed both in Canada and the United States. The writer has studied speci- mens from the following places: New Haven, Connecticut; Gary,

116 Tue UNIversity ScreENcE BULLETIN

Indiana; Douglas county, Kansas; Naples, Maine; Thompson and Cedar River, Michigan; Cooley, Caso Lake and Shevlin, Minnesota; Columbus, Mississippi; Bretton Woods, Notchland, Crawford Notch and Bath, New Hampshire; Erie, Pennsylvania; Windsor, Vermont; Brule and Luxemburg, Wisconsin.

Bruchomorpha abrupta Ball, 1935

Ball, E. D. The Genus Bruchomorpha Newman (Homoptera-Fulgoridae). Bull. Brook. Ent. Soc. XXX, No. 5, pp. 197-203, as B. oculata var. abrupta.

Comparative notes. Doctor Ball described this species merely as a variety of the species oculata Newman. He states that this species has nearly the form of nasuta Stal (beameri n. sp. in this paper), but is larger, with a narrower, rounder nasal protuberance. In his key he separates this from B. oculata var. oculata by having a black body with a broad, white dorsal stripe, but in his description states that the stripe is definite but narrower and reddish, often not ex- tending onto the abdomen.

The writer finds that this species more closely resembles B. oculata Stal than any other. From this species it is separated by having the nasal process more truncate and broader at apex at a point in line with end of frons while in oculata the end of the process is more sloping. The characteristic white stripe which Ball describes is not so apparent in the specimens which the writer studied. The dorsal stripe was more often, at least for the females, more dusky cream to rust, as in oculata, than white. It can be told, however, from oculata in color by having the postelypeus reddish-brown and the general body color being dull black rather than shining bluish-black, and also the dorsal stripe is much more in evidence than in oculata.

The size of the females from apex of head to apex of abdomen is about 2.8mm. to 3mm.

Male genitalia. Tenth abdominal segment (anal flap) tubular at base then extended on its ventral side into a roundingly pointed flap which is not quite twice as long as the tube. The stylus of the eleventh segment is a fingerlike projection extending beyond the dorsal margin of the tube.

Each harpago as viewed from a flattened lateral view is broadest through the middle where its ventral margin is greatly curved. The basal third forms a slender arm and the apex is extended dorsad as a sharply curved, serrate and finely pointed process.

The aedeagus is typical for the genus. The theca covers the aedeagus itself through the middle as a tight membranous sleeve,

DoERING: Z,THE SUBFAMILY ISSINAE a Er

then on its ventral margin projects caudad as two roundingly spatu- late processes which curve dorsad so that their dorsal margins are in line with the thecal margin.

Notes on distribution. Doctor Ball described the holotype ¢ , allotype g¢ and eight paratypes from Sanford, Florida. He states that this is a fairly common summer form in the gulf region.

The writer studied specimens from Beeville, Castroville, Pecos, Alice, San Antonio and Boerne, Texas, and a few from Elmendorf, New Mexico.

Bruchomorpha extensa Ball, 1935

Ball, E. D. The Genus Bruchomorpha Newman (Homoptera-Fulgoridae). Bull. Brook. Ent. Soe. XXX, No. 5, pp. 197-203 as B. oculata var. extensa.

Comparative notes. Doctor Ball considered this merely as a variety of oculata. It is easily distinguished from this species, as he pointed out, however, by its larger size, the more foliaceous nasal process and the broad, creamy dorsal stripe which extends from apex of frons to apex of abdomen.

This species measures 2.8 mm. to 4 mm. in length from apex of head to apex of abdomen in females and 2.8 mm. for males.

The present writer considers that this species superficially re- sembles B. dorsata Fitch more than it does oculata because of the presence of the broad, creamy dorsal stripe. On closer examination it is easily distinguished from dorsata because the latter has an abbreviated nasal process.

Male genitalia. The tenth abdominal segment is very small, scarcely visible beyond the ninth segment. Each harpago as viewed from a flattened lateral view is broadest through the middle where its ventral margin is greatly curved. The basal third tapers to a bluntly pointed base. The dorsoapical angle is extended dorsad as a long slender, curved, sharply pointed process.

The aedeagus is the typical type for the genus. The theca covers the aedeagus through the middle as a tight sleeve, then is extended on the ventral apical region into two flat, spatulate lobes whose width is greater than their length.

Notes on distribution. Doctor Ball’s type locality for the female was Granite Dell, Arizona, and for the male Ashfork, Arizona. He states that this species is found sparingly in the Gulf region and extends through to southern California and north into Utah.

The present writer studied specimens from Pecos, Castroville, Alice, Boerne and San Antonio, Texas, and from Elmendorf, New Mexico.

Bruchomorpha keidensia n. sp. ORIGINAL DESCRIPTION

Size. Length of body from apex of head to apex of abdomen, 9 2.8 mm. and g 2.2 mm.; greatest width of body, 9 1.6 mm. and g¢ 1.1mm; length of tegmen, 9 1.2mm.and ¢ 1.2mm.

Color. A black species similar to B. oculata in general color characteristics. From above all black, this black dull, brownish- black rather than the blue-black or bronze tone of oculata, except for a well-pronounced median stripe of yellowish-tan, starting on the frontal tablet, extending across thorax and somewhat indicated on the median margins of the tegmina, occasionally the stripe a duller reddish-brown or even almost lacking. Underside dark except postelypeus and legs, which are yellow, occasionally washed in fuscous.

Structural details. General appearance similar to B. oculata Newman. From above head protruding beyond eyes about one and one-half times the length of eye. Vertex depressed, exceedingly broad, about eight times wider than length. Frons from above with distinct median carina present and two distinct lateral carinae which are straight, not constricted through middle and frons not depressed as in oculata; the frontal tablet only approximately one-third longer than its greatest width. From side view nasal process long, the lateral carinae converging just posterior to apex, at this point the dorsal margin sloping downward, giving a narrowed look to apex not found in oculata. Ventral margin of postelypeus angulately concave, its length about twice the length of the anteclypeus. Pro- notum and mesonotum with a distinct median carina, latter with additional pair of curved lateral carinae, the characteristic round pits on lateral disks of both segments. Tegmina with venation en- tirely obscured, heavily rugulose, in the female extending only slightly beyond the middle of abdomen, in the male a little longer. Abdomen characteristically globose, only about four segments visi- ble from above; on the exposed segments, a carina indicated on each side, closely followed by a row of circular pits which usually con- sists of four or five by the median half of the carina and one or two at the extreme lateral edge.

Male genitalia. Tenth abdominal segment (anal flap) with ven- tral margin extended into a roundingly pointed flap, the whole structure about twice longer than wide. Eleventh segment showing ubout the usual length beyond the dorsal edge of the tenth segment.

DoERING: THE SUBFAMILY ISSINAE 119

The shape of the harpago and the aedeagal structure with the slight variations and ways they differ from B. oculata and related forms can best be studied by looking at the drawings of these struc- tures.

Comparative notes. ‘This species resembles B. oculata and B. bunni more than any other species in the genus. In color it differs from oculata by being a dull brown-black rather than metallic blu- ish or copper-black and by having usually a well-pronounced me- dian yellow-tan stripe across frons, thorax, and even on to the teg- mina. In oculata this stripe is scarcely ever extended on to the mesonotum. Structurally it is distinguished in the following ways: The frontal process is narrowed due to the apical dorsal margin sloping more abruptly than in oculata; the lateral frontal carinae are not sinuate, the frons is not depressed and the frontal tablet is only approximately one-third longer than its greatest width while in oculata it is two-thirds or more.

For comparison with bunni see the discussion under this heading in the description of that species.

Types and distribution. Male holotype and female allotype col- lected by R. H. Beamer on August 8, 1937, at Keid, Manitoba. A series of thirty-five paratypes, both males and females, taken by R. H. Beamer and C. L. Johnston, same place, and a series of thirty, both sexes, taken by same parties at Mafeking, Manitoba, on August 3, 1938.

Bruchomorpha bunni n. sp.

ORIGINAL DESCRIPTION

Size. Length of body, 2.4 mm. to 3.2 mm.; width of abdomen, 1.1 mm. to 1.7 mm.

Color. Entire body and legs jet black, shiny with a metallic luster, except for a narrow, rusty-yellow stripe extending from just back of the apex of the frons, across the vertex, pronotum and meso- notum and continued as a very faint line across the inner margin of the elytra.

Structural details. Nasal process of median length. From a dor- sal view, head extending beyond eye a distance equal to length of eye. Lateral carinae of frons not sinuate, shape of frons top-shaped. Median carina of frons, pronotum and mesonotum distinct. Tip of nasal process somewhat narrowed at apex, not extended beyond point where lateral carinae of frons converge. At this point the width of the frons is two-thirds the length of the ventral margin of

120 THE UNIVERSITY SCIENCE BULLETIN

the postelypeus. Postelypeus deeply concave. Tegmina moderately long, no distinct longitudinal veins or cells, the entire surface pebbled.

Male genitalia. Each harpago as viewed from a flattened lateral view with both dorsal and ventral margins greatly curved out- wardly, giving it a bulbous appearance, the apical dorsal angle ex- tended into the usual sharply pointed recurved process, which is comparatively shorter than in many species.

The aedeagal structure is typical for the genus with the sleeve of the theca in this case almost square and the extended ventral flaps likewise subequal in length and width. The aedeagus bears two distinct, sharply pointed processes which are exposed through the narrow slit between the theca process and the thecal flap.

Comparative notes. A black species with median rusty stripe ex- tending on to abdomen, usually to apex. Size: Length of body, 2.4 mm. to 3.2 mm.; width, 1.1 to 1.7 mm.

This species is similar in coloring and superficial appearance to the following species: B. oculata, B. keidensia, B. tenebrosa, B. minima and B. suturalis. From oculata it is distinguished by having black legs instead of yellow or light brown and by the carinae of the frons being straight instead of sinuate.

From keidensia it is separated again by its black legs.

From tenebrosa it is separated by the less distinct venation and rugose tegmina and by having the ventral margin of the postclypeus more concave.

From minima it is separated by its larger size, the median light stripe extending on to abdomen, its concave ventral margin of post- clypeus and its body not so parallel-sided.

From suturalis it is easily distinguished by lacking the broad, turned-up nasal process of that species.

Location of types. Holotype male, taken at Grand Canyon, Arizona, on August 11, 1927, by R. H. Beamer; allotype female, Grand Canyon, August 11, 1927, by P. A. Readio. Two female paratypes and nine male paratypes, same data. One female para- type collected in Cochise county, Arizona, by R. H. Beamer, July 20, 1927, and one male at Taos, Taos county, New Mexico, by R. H. Beamer, August 20, 1927.

The types are in Snow Entomological Collection at the University of Kansas.

Nore.—This species has been named in honor of Mr. Ralph Bunn, who for several years was interested in the revision of this genus. Although Mr. Bunn was unable to complete his studies due to pressing duties in other fields, he

Comparative notes. A small, black species measuring from 1.9 mm. to 2.4mm. in length and .93 mm. to 1.33 mm. in width across abdomen. This species very closely resembles B. oculata Newman. The two species are about the same size in actual measurements al- though in looking at a long series of both species B. oculata tends to run larger. In color B. minima is one of the darkest species in the genus, being entirely black with black legs, except occasionally a rusty stripe on frons and thorax. It closely resembles B. oculata in coloring and size, being separated mainly from the latter by having black legs instead of yellow. It closely resembles B. bunni, but is separated from it by lacking the distinct median yellowish-red stripe and by its narrower frontal process. The postclypeus in minima and oculata is one-third longer than the frontal process across apex in line with apex of frons, while in bunni, it is less than this. This species superficially resembles B. mormo Kirkaldy, but is separated very readily from that species by its much longer nasal process. It also might be confused with B. sutwralis and B. tenebrosa.. For comparison with these species see notes under this heading in the descriptions of these species.

Male genitalia. Tenth abdominal segment extended into a short but pointed flap; the whole segment being about equal in length and width. The eleventh segment scarcely visible beyond the tenth and bearing a short, blunt stylus.

Each harpago as viewed from a flattened lateral view roughly crescent-shaped, its basal fourth prolonged into a slender fourth, the median region roughly rectangular, the apical fourth extended dorsad as a sharply pointed, slender hook which is as long as the median portion.

The bilaterally symmetrical aedeagal process is characteristic for the genus. The theca covers the aedeagus through the middle as a snugly fitting membranous sleeve narrowed at base and with its ventral median region extended caudad as two flat spatulate proc- esses which bend dorsad, thus making them appear twice wider than

122 THE UNIVERSITY SCIENCE BULLETIN

long. The sclerotized aedeagus is completely hidden except for a slender, sclerotized hook which extends between the lobes and collar of the aedeagus and bends directly ventrad.

Notes on distribution. Metcalf gives the type locality as Southern Pines, N. C. The writer studied a large series from Yorkstown, Hilliard, and Branford, Fla.

Bruchomorpha tenebrosa n. sp. ORIGINAL DESCRIPTION *

Size. Length of female from apex of head to tip of abdomen 2.75 mm. to 2.95mm. Width of abdomen, 1.3mm. to 1.85 mm.

Color. Body shiny jet black, a dusky brown stripe beginning at a point just back of apex of frons widens gradually, then narrows abruptly at the vertex, continues as a narrow stripe across the vertex and pronotum and widens out again slightly on the mesonotum. No trace of this stripe on the tegmina. The median carinae of the frons, pronotum, and mesonotum show darker on this light stripe. Legs and underside all black, except the membranous region around at- tachment of hind coxae.

Structural details. This species has a medium-sized nasal process. From a dorsal view the head extends beyond the eye a distance ap- proximately equal to length of eye. The median carina is distinct on frons, pronotum and mesonotum. Ventral margin of posteclypeus slightly concave on posterior half, the anterior half somewhat out- wardly expanded; its length as measured from anteclypeus to apex slightly greater than width of frontal process at a point in line with the joining of the lateral carinae of frons which in this species con- verge near apex of head. Tegmina proportionally shorter than in many species, veins prominent forming distinct cells and with less of the pebbled appearance which other species have. Dorsal line of body not arched as in nodosa.

Comparative notes. This species in size, form and the presence of black legs resembles B. bunni, B. minima and B. suturalis very closely. Of these four, bunni and suturalis are southwestern species and minima and tenebrosa southeastern. In color these forms can usually be distinguished by the extent of the median, dorsal light stripe, although since these stripes vary somewhat within the species, they cannot be relied upon too greatly in separating ‘the species definitely. In general, sutwralis has the stripe extending to the apex

45 The writer is indebted to Mr. Ralph Bunn of the Bureau of Entomology for first recog- nizing this species as new, and who in preliminary manuscript, which he bequeathed to the writer, had given this name to the species.

DorERING: THE SUBFAMILY ISSINAB 123

of the abdomen, bunni has it extended on thorax and even across tegmina although here it is narrowed somewhat, tenebrosa has a wide, distinct yellow stripe extending from head to tip of mesonotum, but not onto the tegmina, and minima has a narrow yellow band only on the frons or sometimes, in addition, faintly on the pro- notum.

In addition to color, tenebrosa is separated from bunni by having more rugose tegmina with distinct venation and the ventral margin of postclypeus much less concave than in that species.

From minima it is separated by its larger size, body less parallel- sided and frontal process not so narrowed.

From suturalis it is distinguished by not having the turned-up broad, frontal process, which suturalis has and by the more concave ventral margin of postclypeus.

Location of types. Described from three females. Holotype, col- lected by L. D. Tuthill, Loughman, Fla., August 2, 1980. Two para- types, same place and collector. The types are in the Snow Ento- mological Collection at Lawrence.

ORIGINAL DESCRIPTION

“Subcupreo-nigra, nitida; fronte clypeoque conjunctim parvum productis; venis tegminum distinctus. 9 —Long. 314. Lat. 2 mm. Wisconsin. Dom. Rumbien. Mus. Holm.”

AUTHOR’S DESCRIPTION

Size. Length of body from tip of head to apex of abdomen, 2.6 mm. to 3.5 mm.; width of body at broadest point, 1.6 mm. to 2 mm. Length of tegmen, 1.2 mm. to 1.36 mm. This is one of the largest species of the genus.

Color. General color uniform iridescent black. Occasionally specimens show a narrow bronze stripe following the median carina on frons and vertex. Also some specimens occasionally dark red- brown on head and thorax instead of black, and eyes gray. The en- tire body very shiny. Underside of body the same dark brown to

124 Tue UNIvERSITY ScrENCE BULLETIN

black color, except the less sclerotized areas around the large coxae of hind legs and the extreme apices of the leg segments. .

Structural details. This is a short-nosed species. Length of frons in front of eye as viewed from above less than the length of the eye; its width through middle greater than in many species due to the fact that the frontal sutures which form the lateral boundaries of the frons are carried outward on a wide, sharp carina which from a side view shows as a distinct shelf over eye and gena; the two lateral carinae greatly arched through middle, very close together at base so that the distance between the two is equal to or even less than the distance from one carina to eye. Postelypeus very short, as viewed from the side equal in length to anteclypeus and only ap- proximately one-half as long as the nasal process across its apex, its ventral margin evenly, outwardly rounded. Vertex very short, about eight times wider than long, deeply transversely convex, its anterior and posterior margins sharply elevated. Pronotum pro- portionally shorter than in other species, approximately four times wider than length through middle; a transverse depression indicated just posterior to cephalic margin and a distinct median carina present, on each side of which on the disk are located 17 or 18 con- spicuous circular pits. Mesonotum prominent, not quite twice wider than long, the median carina distinct, two outwardly curving lateral carinae more elevated than it, the space between the lateral and median carinae distinctly concave, each lateral fourth covered by usually eleven circular pits. Tegmina reaching to about middle of abdomen, the longitudinal vein elevated and distinct, but their course difficult to trace because of the deeply rugulose or pebbled surface between them. Abdomen very globose, the anterior segments ex- panded somewhat beyond the lateral margins of the tegmina.

Male genitalia. Tenth abdominal segment (anal flap) with a short, tubular base, from which its posterior ventral region is ex- panded caudad into a rounded flap with parallel lateral margins. The ringlike eleventh segment is visible beyond the dorsal margin of the tube and bears an elongate stylus.

Each harpago as viewed from a flattened lateral view is somewhat crescent-shaped, broadest through base of apical third, and has its apical third greatly lengthened into a slender, pointed, recurved hook.

The aedeagal structure is distinctly different from other members of the genus. The aedeagus itself is a sclerotized structure, bearing at least one slenderly pointed hook near its apex, but the entire structure is practically hidden by the membranous theca which is a

DoERING: THE SUBFAMILY ISSINAE PAS

tubular sheath somewhat narrowed at base, but which broadens caudad and finally ends in two, elongate, pointed flaps.

Comparative notes. This species is not easily confused with other species. It is distinguished by the iridescent black coloring of body and black legs, its greater width of body, very short nasal process and elevated veins in the tegmina.

Notes on distribution. Apparently a well-distributed species. Doctor Ball states, “The writer’s material is all from northern and mountainous regions from Ontario and New York through Wiscon- sin, Iowa, Dakota, Colorado, Montana and Oregon, south in Cali- fornia to Dunsmuir and in Arizona to Oak Creek Canyon. The writer did not take it in Florida and has not taken it in Arizona below the yellow Pine Belt.”

Dozier lists in addition to above-mentioned states New Jersey, North Carolina, Florida, and Texas.

The present writer had additional specimens from Kansas and Minnesota.

Ball, E. D. The Genus Bruchomorpha Newman (Homoptera-Fulgoridae). Bull. Brook. Ent. Soc. XXX, No. 5, pp. 197-203.

Comparative notes. This is a slender, light-colored species, re- sembling superficially an Aphelonema and having the most slender nasal process in the genus. Greatest width of body, 1.2 mm. to 1.8 mm.; length of body, 1.8 mm. to 3 mm. It is easily recognized by the light coloring of the body with touches of fuscous to light brown on head and thorax, the cells of the tegmina between the reticulation washed in varying degrees of fuscous and a series of elongate spots on each half of the abdominal segments which are dark brown and stand out in sharp contrast to the yellowish-tan background. The distinguishing structural characteristics are as follows: The vertex is narrower than in most species, being approxi- mately only three times wider than long; each lateral third of its anterior margin is equal to and at an angle to the median third between the curved lateral frontal carinae and no median carina is present; the frontal process anterior to the eye is shorter than in many species, making it appear to be a short-nosed species, but the nasal process across apex is so slender that the postclypeus is three times longer than the width of this process; the lateral carinae of the mesonotum are sharper than in the majority of species and the disk between is conspicuously concave.

126 THE UNIVERSITY SCIENCE BULLETIN

Male genitalia. Tenth abdominal segment (anal flap) with a short, tubular base, from which its posterior ventral region is ex- panded caudad into a very short, rounded flap. The eleventh seg- ment is ringlike and scarcely visible beyond the 10th and bears an elongate stylus that extends beyond the margin of the flap.

Each harpago as viewed from a flattened lateral view is some- what crescent-shaped, broadest through approximate middle, has its basal third in the form of a pointed arm and the apical third greatly lengthened and projected dorsad as a sharply pointed, slightly recurved hook.

The aedeagus is nearly all hidden by the semisclerotized theca, the latter fitting over the aedeagus as a tight sleeve and then ex- tending caudad as two truncate flaps which bend dorsad, leaving a notch on each side from which protrudes a pointed well-sclerotized, ventrad-curving, aedeagal hook.

Notes on distribution. 'The type locality is Brownsville, Texas. Doctor Metcalf kindly loaned the writer a specimen for study taken at Nogales, Arizona. A long series of this species has been taken in the Santa Rita Mountains by Dr. R. H. Beamer, University of Kansas. Doctor Ball states that he has taken it on range grasses in several places in southern Arizona.

Bruchomorpha decorata Metcalf, 1923

Metcalf, Z. P. The Fulgoridae of Eastern North America. Jr. Elisha Mitchell Soc., p. 188. 1923.

Comparative notes. A medium-sized species varying in length from 2.25 mm. to 2.75 mm. As Metcalf states in the original de- scription, it 1s easily recognized by “its very short nasal process, nearly vertical frons and strongly contrasted colors.” As viewed from above, the head extends beyond the eyes only half the length of the latter and the lateral carinae of the frons are closer to- gether at the base than the distance of one carina to each eye. The vertex is about four times wider than long. As viewed from the side the postelypeus is very short, equal in length to the anteclypeus and extending forward beyond latter a distance which is only about one-third width of nasal procegs across apex. The curved lateral! ‘arinae on mesonotum greatly elevated and very sharp.

Male genitalia. Tenth abdominal segment (anal flap) with a tubular base, from which its posterior ventral margin is expanded caudad into a truncate flap which is about the same length as the tube. The eleventh segment frequently not visible, bearing a pointed stylus.

DoERING: THE SUBFAMILY ISSINAE WATE

Each harpago as viewed from a flattened lateral view is some- what crescent-shaped, broadest through base of apical third, and has its apical third curved dorsad as a pointed process.

The aedeagal structure is similar to that of B. tristis. The aedea- gus is a sclerotized tube entirely hidden by the theca, but bearing two sharply pointed, sclerotized hooks which protrude between the ends of the theca flaps. The theca is tubular at base, then caudad, expands into two elongate, ventral flaps whose apices point dorsad.

Notes on distribution. The type locality is given as Brownsville, Texas. Doctor Ball states that he has taken it also from the Babo- quivari Mts. in Arizona and Cuernavaca, Mexico, and that he finds it strictly confined to a single species of grass, the Arizona foxtail (Chaetochloa grisebachit) as a food plant. The writer had a few specimens at hand from Laredo in addition to Brownsville, Texas, collected by Paul Oman.

Ball, E. D. The Genus Bruchomorpha Newman (Homoptera-Fulgoridae). Bull. Brook. Ent. Soc. XXX, No. 5, pp. 197-2038, 1935.

Comparative notes. This is one of the smallest species in the genus and black in color with yellow legs, washed in fuscous. The length of the body varies from 1.75 mm. to 2 mm. in length for speci- mens which the writer studied, although Kirkaldy states that it is 3mm. long. In coloring it more closely resembles B. tristis, B. minima, B. pallidipes and B. oculata. From the latter it is easily separated by lacking any form of tan or rust median stripe on head and by its very short nasal process. From B. tristis it is easily separated by its much smaller size, its vertical head and its yellow and fuscous colored legs. From B. minima it is separated again by its short nasal process and yellow legs. For comparison with B. pallidipes see notes under that species.

In general the most distinctive characteristics of this species are: from above the head is produced less than half the length of eye, the nasal process is less prominent than in any other species so that the frons is more perpendicular and the frontal tablet is almost circular with the lateral carinae meeting well back of apex; from a side view the postclypeus is equal in length to the anteclypeus and also is about three-fourths of or not quite equal to width of nasal process across apex; the distance of the anterior margin of vertex between the lateral carina is slightly more than the distance from one carina

128 Tue UNIVERSITY ScIENCE BULLETIN

to the eye; median carina and the two lateral carinae of mesonotum distinct and equally raised; vertex very broad, at least six to seven times wider than long.

Male genitalia. The tenth abdominal segment with the tubular base parallel-sided and the flaplike extension of the ventral margin shghtly longer and roundingly pointed. The stylus of the eleventh segment broader than in many species.

The harpago crescent-shaped, broadest through middle, with its basal fourth in the form of a slender, pointed process and its apical fourth sharply pointed and curved dorsad. The aedeagal structure is one of the most peculiar for the genus. The aedeagus is entirely covered by the theca except for a slender sclerotized hook which from a lateral view partially shows between the apical flaps of the theca. The theca is a collarlike tube which is broad at base, then tapers toward the apex, finally ending in two truncate, flat, lateral lobes.

Notes on distribution. The type locality is given as Nogales, Ari- zona. Doctor Ball states that this species is common in southern Arizona. i

ORIGINAL DESCRIPTION

“A small, shiny black species resembling tristis, but with three broad stripes and a very narrow front, widest in the middle. Length, 1.6 mm.

“Front a long oval abruptly pointed below. Much narrower than in mormo and not top-shaped as in most species; the dise flat or con- cave, the bounding carinae light, the median one faint. Nasal proc- ess even shorter and broader than in dorsata, strongly carinate. Color black, a broad, white stripe from apex of front across the first exposed abdominal segment, as wide as frontal carinae at the vertex. A pair of oblique white stripes broadly covering the lower half of clypeus and gradually narrowing to beyond the middle of the elytra. A pair of white crescents arising under the lateral margin of the elytra and curving around to the genitalia. The pustules and legs pale.

“Holotype ¢ , Patagonia, September 10, 1933. Paratype male and a female nymph, Nogales, July 13, 1934. Taken by writer sweeping range grasses.”

Comparative notes. Not easily confused with any species in the genus because of its striped body and very short nasal process.

DoERING: Z,THE SUBFAMILY ISSINAE 129

Male genitalia. Anal flap short, truncate across apex. Harpago more slender than in many species, broadest right at middle, from thence abruptly tapering basally into a pointed base, the posterior half narrowed and finally becoming an elongate slender dorsal- directed hook.

Aedeagus almost completely hidden by the theca. The thecal flaps unique in shape, each flap being boot-shaped and broadest across their dorsal region.

Notes on distribution. This is a rare species to date. Doctor Ball gives the type localities as Patagonia and Nogales, Arizona. Dr. R. H. Beamer collected a female in the Santa Rita Mts., August 17, 1932, and a male at Ruby, Arizona, August 22, 1938.

AUTHOR’S DESCRIPTION

Size. Length of body from tip of head to apex of abdomen, 1.8 mm. to 2.6mm. Greatest width of body, .93 mm. to 1.3mm. Length of tegmen, .8 to 1mm. This is one of the smallest species in the genus.

Color. General color of female uniform reddish-yellow. Male reddish-yellow except the lateral two-thirds of each tegmen which is dark reddish-brown in sharp contrast to the general body color. Underside of body the same general reddish-tan color except for a sharply contrasting dark-brown spot on the median anterior two- thirds of postclypeus. Ovipositor of female sometimes washed in brown.

Structural characteristics. A short-nosed species. As viewed from above the head extends beyond anterior margin of eye only one-half the length of the eye. The frons is top-shaped with a dis-

tinct median carina present and prominent lateral carina which con- verges at base where they join the anterior margins of vertex so that the distance of the vertex margin between them is equal to distance from one carina to the eye. The frontal sutures are not as greatly elevated in front of antenna as in other species.

A nasal process is hardly discernible since as viewed from the side the postclypeus is not bulbous, has an almost straight ventral mar- gin and in length is not much longer than the anteclypeus and is about equal to width of the nasal process across apex. Vertex char- acteristically broad and short, about six times wider than length. Pronotum with a median carina and the usual round pits on each lateral half. Mesonotum with a median and two lateral outwardly curving carinae present which are of about equal distinctness. Rest of thorax and abdomen barrel-shaped. Tegmina less pebbled than in the majority of species.

Male genitalia. The tenth abdominal segment tubular at base and with its ventral margin extended caudad as a roundingly pointed flap which is twice longer than the tube. The eleventh segment scarcely visible except for its stylus.

Harpagones more slender than in most species, typically crescent- shaped, with the broadest part at middle and at either end tapering to sharply pointed, slender processes.

The aedeagus is practically hidden by the theca which covers the aedeagus as a tubular sleeve and has its ventral posterior margin extended caudad as two spatulate processes.

Comparative notes. B. jocosa is readily distinguished from every- thing else in the genus by its short nasal process and the character- istic dark spot on apex of postclypeus.

Notes on distribution. Dozier records this from South Carolina, Florida, Kansas and Texas. Doctor Ball states that “this form is abundant throughout the Gulf region and is occasionally taken as far north as Virginia, Iowa and Nebraska.”

yellow with a dusky stripe on the thighs. Length, 0.16. Mr. Robert- son has discovered individuals having the wing covers and wings fully developed, showing that it is a pupa which is described by Mr. Newman. As it may be as Mr. Westwood suggests in a letter to me, that these insects, like some of the Nepidae and other species belonging to this order, attain to puberty and perish without ac- quiring wings, whilst other individuals of the same species become fully developed.”

Synonymy. The writer agrees with Doctor Ball that flavo-vittata Stal is a synonym of this species. Stal’s original description of flavo-vittata is as follows:

“Nigra, subcupreo-nitens; vitta utrimque angustata, ab apice frontis ad apicem abdominalis ducta pedibusque dilute flavescenti- bus, hic fusco-vittatis; fronte clypeoque conjunctim nodice productis.

AUTHOR’S DESCRIPTION

Size. Length of body from tip of head to apex of abdomen, 2 mm. to 3 mm.; width, 1 mm. to 1.5mm. Length of tegmen, .9 mm. ~

Color. Uniform dark shining species with a broad, yellow stripe down back. Frons, vertex and thorax a deep reddish-brown, with the median yellow band one-third the width of the vertex down to apex of mesonotum where it broadens a trifle. Tegmina and abdo- men shining black with the yellow median stripe slightly broader throughout the length of tegmen, then becoming approximately same width as on frons and vertex and extending the full length of abdo- men, including base of anai flap. Underside of body for the most part reddish-brown. Apex of postclypeus, all of anteclypeus and labrum, the beak, the less sclerotized areas around the coxal bases, and the caudal areas of the last few abdominal segments yellow to tan. Legs all yellow or with basal half of coxae and a lateral stripe on the tibiae fuscous.

Structural details. A short-nosed species. As viewed from above the frons extends beyond eye a distance less than the eye itself, a median carina distinct, two lateral carinae moderately, outwardly rounded, the distance between them at base about equal to the distance from one carina to each eye, the frontal sutures forming the lateral boundaries of the head and raised on a moderately sharp carina over each eye and gena. Postclypeus as viewed from the side very short, equal in length to anteclypeus, less than the width of the frontal process across apex. Vertex transversely con-

cave, about five times wider than length through middle. Meso- notum approximately three times wider than long, between the eyes roundingly produced forward over half the length of eye, its lateral cover from above almost completely overlapped by eye, then on extreme sides again expanded into a roundingly pointed flap which almost covers pleural region; the disk between mesal margin of eye and dorsal stripe covered with approximately sixteen round pits, a distinct median carina present. Mesonotum twice wider than long, a distinct median and two conspicuous lateral carinae present on each side of which in the disk are approximately eleven round pits. Tegmina approximately half the length of the abdomen with less rugulose appearance and less prominent longitudinal veins than in other species. Abdomen characteristically globose, showing five segments visible from above, on each side just back of anterior border a faint carina visible just back of which is a row of four round pits and one at extreme side.

Male genitalia. Tenth abdominal segment (anal flap) with a short tubular base, from which its posterior ventral region is ex- panded caudad into a pointed flap. The ringlike eleventh segment is only slightly visible and bears a moderately long stylus.

Each harpago is crescent-shaped, broadest through middle, its basal fourth forming a slender pointed arm and its apical fourth prolonged dorsad as a pointed process. The sclerotized aedeagus is covered through the middle by the tubular membranous theca which is somewhat narrowed at base and has its ventral posterior region projected caudad as two rounded spatulate lobes. Sclerotized aedea- gal hooks are visible between the tubular part of the theca and the flaps.

Comparative notes. There are four species in the genus which are black with hght cream, median longitudinal bands of considerable width. These are B. dorsata, B. extensa, B. beameri and B. suturalis. The latter two do not have the stripe extending across the abdomen to any extent. Dorsata is easily separated then, from B. extensa because of its very short nasal process.

Notes on distribution. Doctor Ball states that it is a northern species ranging from New York and North Carolina to Dakota and Kansas.

Dozier reports it from the following states: Arkansas, Colorado, Kansas, Iowa, Missouri, Ohio, North Carolina, New Jersey, New York, Texas, and Wisconsin.

AUTHOR’S DESCRIPTION

Size. Length of body from tip of head to apex of abdomen, 2.2 mm. to 2.6 mm.; width, 1.1mm. to 1.86mm. Length of tegmen, 1.06 mm. to 1.1 mm.

Color. General color resembling oculata and nasuta. Head and thorax from above a rich brown to blackish, but usually a lighter shade than tegmina and abdomen. A median testaceous yellow to dronze median longitudinal band on frons, vertex and pronotum, which in width is about one-fifth the width of vertex. On meso- notum and claval margins of tegmina this broadens somewhat and at sides indistinguishably blends into the darker coloring of the sides. Eyes dark brown, margined in light and frequently spotted with light. Tegmina and abdomen deep brown to pitch, usually quite shining. Underside of body shining dark brown to black except the less sclerotized areas of the thorax. Legs usually testaceous yellow with the coxae and sometimes the bases of other segments somewhat darker, or sometimes legs are all fuscous except at apices of the segments.

Structural characteristics. A short-nosed species. Frons, as viewed from above, extending beyond eye a distance slightly less than length of eye, its lateral carinae at base placed closer to median carina so that the distance between the two lateral carinae is equal to the distance from one carina to the median margin of eye, united just before apex; frontal suture elevated in a sharp carina which hangs shelflike over the gena on which is situated the antenna; ventral margin of postclypeus only slightly convex, its length at this point approximately equal to width of nasal process across its apex. Vertex approximately six times wider than long, transversely concave and a faint median carina present. Pronotum characteristic

of the genus in shape, with a distinct median carina and about 18 or 19 pits on each lateral dorsal disk; its extreme lateral third extended around and under eye as a short collar, not visible from above, but which again broadens at the side into a pointed ventrad projecting flap, bearing four round pits just cephalad of its posterior margin. Mesonotum not as long as in some species, approximately twice wider than long; a distinct and sharp median carina present; two lateral carinae only faintly indicated, if at all. Tegmina extending to slightly over half length of abdomen, longitudinal veins indistinct, their entire surface more pebbled than in other species. Abdomen barrel-shaped, with five segments visible, lateral carinae present on anterior margin of each segment just back of which are single rows of four to five round pits.

Male genitalia. Tenth abdominal segment (anal flap) with a short tubular base, from which its posterior ventral region is ex- tended caudad as a bluntly pointed flap. The ringlike eleventh segment shows beyond the dorsal margin of the tube and bears a blunt, fingerlike stylus.

Each harpago, as viewed from a flattened lateral view, is some- what crescent-shaped, broadest at apex of basal third and has its apical third greatly lengthened into a slender, sharply pointed, dorsad curving hook.

The aedeagal structure is bilaterally symmetrical. The sclero- tized aedeagus is covered through middle by the tubular membra- nous theca which is somewhat narrowed through middle and has its ventral posterior region projected caudad as two rounded spatulate lobes. Sclerotized aedeagal hooks are visible between the tubular part of the theca and the flaps.

Comparative notes. Size and form of B. minima and B. mormo. Also resembles B. suturalis and B. oculata. From both B. suturalis and B. minima it is separated by its extremely short nasal process and yellow legs. From B. oculata it is separated by its smaller size and short nasal process. From B. mormo it is separated by having an indication of a dorsal median stripe on head and thorax, a shorter postclypeus, an elongate top-shaped frontal tablet instead of the circular one as in that species.

Notes on distribution. Dozier states that this species is recorded from Virginia, South Carolina, Florida, Kansas, Colorado, and adds Mississippi. In addition to these states the writer studied specimens from Alabama, Louisiana, and a large series from Washington, D.C.

Comparative notes. This genus is recognized by having narrow, strap-shaped wing covers, somewhat triangularly widened at base and tapering at tip, where they become acutely rounded; contracted angulate head with an oblong quadrangular vertex having acutely prominent angles; front oblong, with sides and middle line promi- nently carinate; pronotum transverse, short, depressed on the disk, the anterior angle subacute, with the sides narrow and curved down- ward; scutellum triangular, carinate, acute at tip; wings rudimen- tary; hind tibiae with four laterally placed spines; abdomen obese, carinated above.

HISTORY OF THE GENUS

The genus was described by P. R. Uhler in 1889 with manca as the haplotype. In 1906 Melichar added an additional species, lwrida. Kirkaldy in 1908, with no reference to lurida, described two new species, barbarae and artemesiae, which he compared to manca only.

Since Kirkaldy states that the tegmina vary in length in barbarae, also, Van Duzee, in collecting manca, states that this species varies from a fulvous brown to dark fuscous with sometimes a dorsal stripe and the elytra whitish or grey, and since on outward appearance the present writer as well as coworkers have found them to be difficult to separate, it makes the status of the named species somewhat dubious. Moreover, the types of none of the three latter species have been available for study. Yet by means of the male genitalia and certain minute, yet distinct external characters, the writer be- lieves that these four species can be differentiated, with perhaps lurida remaining as the most doubtful.

To the four named species are being added two new species, D. adiuncta and D. robusta. These are sufficiently different in shape of tegmina and genitalia from the older species involved to warrant describing them as new.

ORIGINAL DESCRIPTION

“Grayish fuscous, pubescent, tinged with white, pale yellowish- brown when immature. Upper surface and wing covers scabrous. Head rough, a little hairy, the carinate lines blackish, interrupted with white; lower part of cheeks and epistoma pale testaceous. Legs and tarsi spotted with fuscous. Pronotum a little pale about the margins. Pectus hairy, unevenly fuscous, marked with a white spot above the orifice of the mesothoracic spiracle. Underside chiefly paler than above, sometimes testaceous, or white on the posterior coxae. Wingcovers ashen gray, with chiefly black veins, the veins of the costal and inner border coarsely interrupted with white, while those of the diseal portion are minutely speckled with white. Anal and genital segments more or less rusty yellow. Length to tip of wing covers, 4144 to 5mm.; to end of venter, 314 to 444mm.; width of pronotum, 13%, to 2mm. This insect has thus far been reported only from Los Angeles, Cal., from which place several specimens have been referred to me for examination by Mr. D. W. Coquillet.

“Tt is the most remarkable insect of the order which has yet been discovered in North America. The wing covers lack the membranal area which is so often present in the insects of this group, while the form of these organs and their type of venation lead to the Orthoptera of the group Acrididae, and thus give us an ancestral

138 THE UNIVERSITY ScIENCE BULLETIN

type which might well be a remnant of the old Fauna prevalent in the Rocky Mountain region during the Tertiary period.”

Comparative notes. This species is not readily separated from D. barbarae Kirk., D. artemesiae Kirk., or D. lurida Mel. By close comparison it is separated by the following characteristics: Pro- notum and vertex through middle of equal length, vertex more taper- ing anteriorly, the rounded anterior margin of pronotum distinetly wider than vertex at base, dorsal and ventral margins of frons not noticeably different in width, the former being only one-fourth greater; cells of the tegmina more evenly rectangular than in other species; tegmina narrow, but usually not much longer than tip of abdomen.

Male genitalia. Anal flap moderately emarginate at apex. Each harpago, as seen from a flattened lateral view, has its ventral margin outwardly rounded and its dorsoapical angle extended ceph- alad as a sharply pointed projection at base of which is an ab- breviated, sharp mesal spine and on the outside a recurved hook.

The aedeagus is tubular with its extreme apex somewhat flattened, then narrowing into a blunt point. The tubular theca covers the approximate basal fifth. Attached near the base of the aedeagus and projecting beyond the posterior margin of the theca are two, thick, slightly curved hooks which are shorter than those in other species, while a second larger pair arise just caudad of middle, one on either side, whose apices are sharply pointed and project ceph- alad.

Distributional notes. Described from Los Angeles, Cal. Van Duzee (1914) states that it is ‘abundant everywhere on Adenos- toma and Artemiscia and comes to maturity about April 1, but specimens may be occasionally found throughout the autumn and winter.”

Specimens are at hand for study from the following places in California: Alameda county, Claremont, Del Mar, Lempoc, Mon- terey, Mt. Diablo, Newton, Nipomo, San Diego, Santa Cruz Mt.,” Stimson Beach and Ventura.

“Nordamerika, Claremont, Cal. Zwei Exemplare von Baker in meiner Sammlung.”

Comparative notes. This species is very difficult to separate from D.manca. This brings out two problems. Since the type cannot be located, it is not at all certain that the author has recognized the proper form as lurida, and, secondly, if the forms classified as lwrida in this paper are correctly named, it still might be debatable as a valid species since the characters for separation are not very obvious.

It differs from manca by having the dorsal margin of the frons deeply angled instead of being truncate as in manca, by having the lateral margins of frons straighter and converging at base, by having the tegmina slightly wider at base than in manca with the longi- tudinal veins beyond middle converging at various points, making the apical half more reticulated and not such uniform rectangular cells present as in manca. The aedeagus is quite distinct from manca, as can be seen in the drawings.

Male genitalia. The anal flap of this species seems to be more deeply emarginate than in artemesiae. The harpago, as viewed in flattened lateral view, has the posterior, ventral margin angulate, while in other species it is rounded at this point.

The aedeagus differs from other species in the genus, mainly by having the left hook of the posterior pair angulately bent, forming a boot-shaped structure, whose apex is directed caudad. The basal hooks of the theca are longer than in manca and less curved, extend- ing at least to apex of basal third of theca.

Notes on distribution. Claremont, California, is given as the type locality. The series of specimens studied for this paper are from San Jacinto Mts., Stimson Beach, San Francisco, and Montara, California.

D. barbarae. Antennae dark fuscous. Tegmina piceous or blackish (instead of yellowish-brown), with paler markings. The tegmina are narrower and the pronotum is shorter than in D. barbarae, more so even than in D. manca. Length, @ 414% mm.

“Hab. California, Alameda (Perkins) on Artemesia.”

Comparative notes. This species is very similar to D. manca and D. lurida. It differs from manca mainly by the longer pronotum, which is approximately twice the length of the vertex, while in manca the two are the same length; the frons narrowed considerably at dorsal margin, at this point being half again as wide as at ventral area; the tegmina has usually a prominent middle vein from which it seems the others tend to branch off rather than the parallel longi- tudinal veins of manca.

From lurida it is separated by not having the basal margin of the frons angled as in lurida and again by the prominent middle vein of the tegmen.

Male genitalia. The anal flap of this species seems to be more truncate at apex than in manca or lurida, with its lateral margins parallel. The harpago is larger with its apical fourth narrowing into an elongate, dorsal recurved arm.

The aedeagal structure is distinct. The theca itself is proportion- ally longer. The distal portion of the aedeagus is broadened con- siderably, much curled under the shaft part and finally ends in a sharp, recurved spine. The basal hooks of the aedeagus are much longer than in any other species, reaching at least to middle. The posterior lateral hooks are greatly reduced to mere prongs.

Geographical distribution. Deseribed from Alameda, California. Specimens were on hand for study from the following places in Cali- fornia: Cajon, Del Mar, Lempoc, Mint Canyon, Nipomo, Topango Canyon, and Ventura.

ORIGINAL DESCRIPTION

“This is close to D. manca Uhler, but differs by the basally trun- cate frons, which is also much wider in proportion, widening towards the apex. The vertex is shorter and wider, the lateral margins paral- lel (converging very slightly anteriorwards, if anything), the anterior margin very obtuse-angled. The pronotum is rather more produced anteriorly, its lateral margins more arched. Antennae yellowish- testaceous. The tegmina vary in length.

“Length, 9 5% mill.

“Hab., Cal., Santa Barbara foothills, July (Gifford) .”

Comparative notes. ‘This species seems to be a slightly larger species with longer tegmina than the other species in the genus. It is separated from other species externally by having a broad frons, with lateral margins outwardly curving, across ventral area being only one-sixth wider than at dorsal margin; by having long pro- notum, being one and one-half times longer than vertex through middle; by having a wide vertex, with its anterior margin one-third wider than one lateral margin; wing venation forming an uneven network.

Male genitalia. Harpago as viewed from a flattened lateral view, crescent-shaped, larger than in other species and with the dorsoapical corner projecting dorsad as a sharply pointed projection, at base of which is the usual recurved spine, which in this species is more fingerlike and longer than it is in the closely related species.

The aedeagus is distinctly different. The theca is proportionally longer, with the ventrad portion longer than the ventral. The basal hooks of the theca broad across the base, sharply narrowing to the pointed apex, which is about at middle. The two lateral hooks are more reduced than in artemesiae, being reduced to mere pointed ex- tensions of the lateral margins.

Distributional notes. The type locality is given as Santa Barbara, California. Specimens were on hand for study from the San Jacinto Mountains, California.

Danepteryx adiuncta n. sp. ORIGINAL DESCRIPTION

Size. Length of body from tip of head to apex of tegmen, 3.5 to 3.7 mm.; greatest width of body, 1.5 mm. to 1.75 mm.

This is a robust species with broader, shorter tegmina than in the older species, but not quite as short stature as in robusta n. sp.

Color. Characteristically mottled as are all the members of the genus. General body color from above reddish-brown mottled with tan, carinae yellow or hght tan, extreme carinate edges of vertex and pronotum dark brown followed immediately by a thin border of hight tan. Eyes mottled dark brown. Segments of abdomen shaded with dark on posterior margins. Underside of body lighter, mottled with dark. Legs light tan with irregular splashes of brown, spines on tibiae and tarsi dark brown to black. Tegmina with dark-brown background, veins light yellow and margin all around bordered with uniform roundish light yellow spots.

142 Tue UNIVERSITY SCIENCE BULLETIN

Structure. Vertex broad, one lateral margin and anterior margin twice the length at middle from apex to occipital declivity. Frons broad, margins distinctly outwardly bowed, greatest width at base of ventral third, at this point approximately one-fourth wider than across dorsal margin. Pronotum typical, with the arched central re- gion with the sharply defined carinae extending forward into head region only half the distance of the eyes. Mesonotum with sharply elevated carinae. Abdominal segments carinated at middle. Teg- mina short, through basal third almost twice wider than apical third, the claval region short, with inner margins almost touching, the basal third of costal margin greatly expanded, then suddenly constricted at middle from which point it gently curves to the rounded apex. Tegmina with one prominent longitudinal vein at middle, the rest of veins forming an irregular network, all veins conspicuous and greatly elevated.

Male genitalia. Anal flap short, parallel-sided, the apical margin deeply, roundingly emarginate. Eleventh abdominal segment show- ing as a broad, short, ringlike segment, the stylus moderately long.

The harpago, as viewed from flattened lateral view, has its ventral and apical margin greatly rounded, the apical dorsal extension is moderately long, sharply pointed and bears at its base on the outside a medium sized, recurved external hook.

The aedeagus is a semicircular tube which is concave ventrad and at apex ends as a truncate flap. Attached near its base and project- ing slightly beyond the posterior margin of the theca are two slender, curved hooks. Just posterior to the apex is another pair of small hooks whose apices are directed cephalo-dorsad. These hooks are placed much nearer the apex than in other species. The theca is more abbreviated in this species than in the others.

Comparative notes. This species is easily distinguished from the other older species by the broadened tegmina which have their claval margins adjacent. It is more similar to D. robusta n. sp. because of this condition, but is separated from this species because the apical half of the tegmen is greatly narrowed again and by having a coarser reticulation and less pronounced median longitudinal vein.

Location of types and distribution. Holotype male, collected by R. I. Sailer, at Monterey, Cal., August 10, 1938; holotype female, same place and collector. Four paratypes, same data.

Danepteryx robusta n. sp. ORIGINAL DESCRIPTION

Size. Small, robust species; length of body from tip of head to apex of tegmen, 3 to 3.5 mm.; width of body through thorax, 1.4 mm.

Color. Color tan, general color lighter than in other species. Ver- tex and pronotum yellowish-tan with outer carinate margins brown. Eyes reddish-brown mottled with dark. Pronotum tan with carinae light yellow. Frons and postelypeus mottled with minute irregular splashes of reddish-brown, the thin carinate edges dark brown. Thorax yellowish-tan. Legs yellow splashed with irregular specks of dark brown, tips of tibial spines, claws, and last segment of tarsi dark brown. Thorax yellow. Abdomen yellow, with some of the segments at the sides and towards posterior margins darker, the disks of first abdominal segments dotted with round brown spots. Teg- mina mostly yellowish-tan, dimly mottled lengthwise through mid- dle with fuscous, the veins standing out distinctly yellow against this darker background.

Structure. Vertex broad, anterior margin and lateral margin equal, almost twice the length at middle from apex to occipital de- clivity. Frons narrow as in manca, being about one-third wider through ventral third than across dorsal margin which is truncate or only very slightly angulate. Pronotum short, length through middle not more than one-third longer than median length of vertex. Meso- notum with three sharp carinae. Tegmina short, broad, with claval margins adjacent, rest of inner margins almost touching due to the fact that the costal margins and entire inner margins are parallel and that the base of the wing is not expanded as in adiiincta. Wing venation similar to that of artemesiae with a prominent middle vein, posterior to which the cells are small and the veins are not greatly elevated.

Male genitalia. Anal flap (tenth abdominal segment) long, with the ventral region extended into a deeply, roundingly notched flap which is about again as long as the tube itself. The ringlike eleventh segment conspicuous with an exceptionally long fingerlike flap.

The harpago small, having no greatly extended apical dorsal hook and a short external hook just anterior to apex.

The aedeagus is a semicircular tube which is concave on the ven- tral side and at apex bluntly pointed. Attached somewhere near the base of the aedeagus and projecting beyond the posterior margin of the theca are two thick, slightly curved pointed hooks, which are sickle-shaped and of median length. A second pair of aedeagal

144 Tue University SCIENCE BULLETIN

hooks arises just eaudad of middle whose sharp-pointed apices are directed cephalad. The sleevelike theca covers the approximate basal third.

Color phase. A few specimens, taken at the same time and place as the typical form show a variation in color by having the fuscous markings much more pronounced, thus, in general, being much carker in coloring.

Comparative notes. This species resembles more closely D. adi- uncta and D. artemesiae. Like artemesiae it has the prominent me- dian longitudinal yein beyond which the cells are small due to finer reticulation. It differs from this species by having the shorter, broader tegmina which adjoin along claval and inner margins. It is similar to adiuncta by the adjoining of the tegmina, but differs from this species by having the costal and claval margins parallel and the basal region of the tegmen not expanded as in adiuncta. Also, adi- uncta does not have the pronounced middle vein with the cells pos- terior to it small and the veins fine, but all veins are coarse.

ORIGINAL DESCRIPTION OF THE GENUS

“Resembling Tylana Stal (as represented by ustulata Uhl.) and Ulixes Stal in general form and structure, but with a much narrower and more acutely angled head which is produced into two long, di- vergent processes extending obliquely forward and upwards, two and one-half times the length of the eye. Superficially resembling Lusanda Stal from Ceylon, but in that genus the head is broad, and the projections point obliquely downwards. Vertex one and one-half

times as long as its basal width, nearly that much longer than the pronotum, the dise with a deep angular trough, the two projections triangular in shape, inclined upward, the angle between them acute and extending down to expose the carina of the front. Pronotum and mesonotum as in Tylana except that there are three large tu- bercles in the lateral compartments on each side of the latter. Elytra longer and more definitely angled behind with a longer inflated bulla than in Tylana. Venation reticulate and similar to that in 7. ustu- lata. Front one-half longer and no wider than in Tylana, 5-carinate, the intermediate carina rounding in above and not extending onto the projections. The whole insect clothed with long stiff bristles. “Type of the genus 7. bifurca, n. sp.”

Tylanira bifurca, Ball

“Form of the genus, resembling Tylana ustulata Uhl., larger with a much longer, narrower head and pronotum giving the insect a wedge-shaped appearance anteriorly and a blunt wedge posteriorly. Length, ¢ 8mm.,or ¢ 7 mm.

“General color lighter brown than in ustulata with a definite gray- ish cast, the cinnamon chevrons of ustulata reduced to pale ovals while there are two smaller spots behind connected by a broken line. Holotype ¢, allotype g, and a pair of paratypes, Benson, Ariz., June 7, 1930, and one female, Fort Hancock, Texas, June 9, 1930. All taken by J. O. Martin and received through the kindness of E. P. Van Duzee of the California Academy of Sciences. Types in that museum, a paratype ¢ in the author’s collection.

“This is the largest and most striking Issid yet recorded from the United States.”

ORIGINAL DESCRIPTION OF THE GENUS

“Allied to Aphelonema, but much more elongate in form, with the vertex as long as wide, the eyes enclosing only about half the pro- notum and the front triangular, broadest below.

“Vertex flat, long and narrow, longer than pronotum, equaling the mesonotum, as long as its basal width. Head with the eyes definitely narrower than the pronotum which is constricted on the anterior half and enclosed by the eyes and then widened and laterally carinate posteriorly, but again exceeded in width by the elytra and abdomen. (In Aphelonema the insect is barrel-shaped, the head almost as wide

as the body.) Pronotum extremely long and narrow, almost as long as wide, the lateral margins carinate and broadly pustulate, meso- notum elongate, the lateral carinae extremely high and enclosing a tablet that is much longer than wide. Elytra brachypterous, cover- ing over one-half the abdomen, the sutural line depressed in middle, the posterior margin rounding with an inflated area in front on either side. Venation as in Aphelonema. Hind tibiae with a single stout spine. Face elongate, retreating, forming a 30° angle with vertex. Front the shape of a rather long flatiron. Truncate with two pustules below. The lateral pustulate areas extremely wide above.

“Type of genus: Papagona papoosa n. sp.

Comparative notes. The present writer has not seen the type species of the genus. Doctor Ball very kindly donated a paratype of P. succinea. This species shows all the differences between this genus and Aphelonema, as pointed out in the original description given above.

ORIGINAL DESCRIPTION

“A gray and brown species with a long vertex, a broad median white stripe and three pairs of white spots. Length: ¢ , 2.6 mm.

“Vertex long, tapering, deeply concave, the postocular carina of the pronotal flaps rounding, only a little higher than the carinate lower margin. Mesonotum with the median portion flat. Front much longer than its apical width. The lateral margins of the pus- tulate areas very weakly carinate.

“Color, pale straw, a broad median white stripe to the apex of the mesonotum narrowing posteriorly. The outer inflated portion of elytra and the median inflated portion of abdomen piceous, a pair of round, waxy spots back of the hinge on the elytra, a smaller pair in the saddle, a large pair on outer portion of the first exposed segment and often three approximate dots along the median line. Below and legs dark brown, shading out to straw on the front. The coxae and venter pale blue.

“Holotype ¢, taken from bluffs of the Santa Cruz river near Tubac, Ariz., August, 1932. Paratype g in the same spot, May, 1932. Both swept by the author from a clump of joint grass (Mah- lenbergui porteri).”

Papagona succinea Ball, 1935 (Plate XV, figs. 2, 2a, 2b)

Comparative notes. Doctor Ball states that this species is sep- arated from papoosa by the following differences: By having a shorter head and vertex definitely shorter with apex more bluntly rounding and the dise almost flat with the marginal carinae raised instead of disc being deeply concave as in papoosa; by having the frontal tabiet definitely broader and more rapidly narrowing than in papoosa; by having a depressed mesonotum, and by being a rich amber color without the median stripe.

Notes on distribution and location of types. The types were col- lected by Doctor Ball in the Tucson Mountains, Arizona, and Sabino Canyon of the Santa Catalina Mountains in April on small clump grass, Triodia mutica Benth.

THE GENUS NORVELLINA (HOMOPTERA, CICADELLIDAE)

HIS paper is an attempt to define the generic concepts of the

genus Norvellina and to present a systematic treatment of the species, old and new, contained within the genus. In the preparation of this paper the writer is deeply indebted to Dr. R. H. Beamer, under whom the study was carried on and without whose advice and encouragement the endeavor would have perished; to Dr. E. D. Ball, whose generous loan of type material and gift of information con- cerning the host preferences of some of the closely related species enabled the writer to confirm specific differences in structure; to Mr. P. W. Oman for the valuable loan of undetermined material and for numerous comparisons with types in the National Museum as well as general information on the genus; to Mr. E. W. Davis for the unselfish loan of all his material in this and related genera for study; and to Colorado State College for the loan of type material from their collection.

Linpsay: THE Genus NorvELLINA L7t

SYNOPSIS OF THE GENUS

The genus Norvellina was erected in 1931 by Dr. E. D. Ball and Eutettix mildredae Ball designated as Genotype. The following is the generic description (Fla. Ent., XV, p. 2, 1931):

“Resembling Hutettiz in the transverse depression on vertex and single cross nervure; much narrower and trimmer in build with definite pattern or saddle markings.

Vertex much broader than long, almost parallel margined, broadly rounded or slightly angulate with front. Head with the eyes equalling the pronotum or folded elytra in width. Pronotum decidedly longer than in Platymetopius and its allies. As seen from the side, the pronotum is strongly arched and sloping down in front, the vertex sloping in the same curve until just before the apex where there is a definite horizontal shelf which extends from eye to eye, an- terior margin bluntly rounding and almost right-angled with face. Elytra closely folded at rest. Venation simple, regular, only one cross nervure, no true costal veinlets except the two at the ends of the first apical cell. Elytra covered by a ‘saddle’ pattern made up of contrasting colours and reticulations.

This genus embraces some twenty or more largely western species of which Eutettix seminuda (Say) and chenopodw Osb. are the common eastern repre- sentatives. From Eutettixz, sensus strict, they are readily separated by the saddle pattern, the vermiculate reticulations and the narrower, lighter form. The genital pattern is simple and of relatively little value in either group.”

The “twenty or more” species referred to above can be reasonably determined by a process of elimination, since in the same publica- tion with the above description Doctor Ball placed clarivida, insana, paupercula, tenella and stricta in the genus Opsius. In later writ- ings they have been placed in Norvellina, as well as the twenty-one following species:

mildredae amanda rubida perelegantis snow texana pullata saucia ziczac scitula nevada bicolorata chenopodiu pulchella apachana seminuda albida helenae columbiana pannosa oregona

Numerous dissections of the males of the species definitely Nor- vellina on the basis of the “saddle marking” brought forth the fol- lowing nearly stable characters which may serve to help limit the genus. The main generic character apparently is a pygofer gen- erally rounding on the ventral margin to a dorsally directed hook arising on the posterior margin. Variations in the width of the pygofer are frequent and specific, but only one species, N. pulchella (Bak.), in which the hook arises on the involute ventral margin of the pygofer and is directed posteriorly, varies from the general

definition in respect to the hook. A second character found con- stant in its general structure is the aedeagus, which consists of a somewhat foot-shaped base, from the heel of which arises a tubular shaft with two more or less closely appressed ventrolateral proc- esses arising near the base and usually extending about the length of the shaft. The variations in the shape of this structure were found to be specific within the known species. In addition the styles of all the forms are inwardly geniculate on the distal half, the apical portions of which are more or less cylindrical, varying slightly in length and curvature.

On the basis of the above limiting characters further dissections were made of all the species in question, as well as numerous other forms showing external similarities. As a result the following nineteen species are herein retained in the genus Norvellina:

mildredae snow texana perelegantis saucia bicolorata pullata nevada apachana scitula pulchella helenae chenopodii pannosa clarivida seminuda rubida- scaber

columbiana

One species is placed in synonomy (JN. oregona Ball is a synonoym of N. rubida) and the following two new varieties and eight new species were described in Jour. Kans. Ent. Soc. Vol. 11, 1938:

mildredae var. minuta numerosa bicolorata var. inflata excavata flavida rostrata vermiculata curvata varia glauca

A few additional specimens are at hand which differ considerably from the above listed forms, but further collecting is necessary to establish their validity as good species.

The seven species and one variety that follow do not agree with the Norvellina structures and are disposed of, by Mr. P. W. Oman of the National Museum, as follows:

Eutettix ziczac Crumb is a synonym of Phlepsius utahnus Ball.

Eutettix stricta Ball belongs in the genus Ollarianus Ball.

Eutettix amanda Ball—_——?

Eutettix tenella (Baker) should remain in Lutettix for the present.

Eutettix insana Ball, E. insana var. coronata Ball, EZ. paupercula

(Ball) and Plepsius albidus Ball seem to be congeneric and probably need a new genus.

Linpsay: THe Genus NorvELLINA 173

A study of the genus, as it is considered here, reveals that there are three main types of patterns, one of which is the original “saddle” pattern under which subdivisions may be made. Of the other two, one is the type in which the dark pattern is confined to the anterior and posterior regions, leaving the basal two-thirds of the elytra without markings, while the other is simply a lack of any definite pattern, as exemplified in N. clarivida, texana and glauca. In the first case N. apachana, bicolorata and bicolorata var. inflata are the examples. The remaining twenty-three species bear a saddle of some kind, varying from the definite median pattern extending from the vertex to the unions of the claval sutures and mesal mar- gins where it flares to the costal plaques, to patterns representing the remnants of this solid pattern.

GENERAL DISTRIBUTION

The genus Norvellina is a native insect of North America and in general a western and southwestern form, many species of which are indigenous to mountain and submountain regions. According to Doctor Ball they are more or less constant in host preference. Only two specimens from Mexico have been examined by the writer, al- though certain of the other known species probably occur there. A few species, such as N. seminuda (Say), occur in general distribu- tion in the east and central states. N. chenopodi (Osborn) appar- ently is widely distributed over the northern portion of the United States and the southern provinces of Canada as well as south at least through Kansas. N. helenae Ball occurs throughout the south- ern states and cotton belt and north into Kansas and Nebraska, where apparently it hybridizes with N. chenopodii (Osborn) which it so closely resembles. Most of the other forms are distinetly western in distribution and comparatively rare in occurrence, as evidenced by the short series taken at any one time and place.

TECHNIQUE IN STUDY

As a result of numerous dissections it was found the most advis- able method of studying the genitalia of the males of this genus is as follows: After briefly boiling the detached abdomen in ten per- cent caustic potash, rinsing in water, and placing in a drop of glyc- erin upon a slide, the genital capsule is split along the lateral sutures. The pygofer and the combination of valve, plates, styles and aedeagus are then spread separately. In turn these are flattened under a cover slip, the slide numbered to correspond to the pinned specimen, and the above structures microphotographed. These photographs are in reality only negative prints, since they are made

176 THE UNIVERSITY SCIENCE BULLETIN

Norvellina apachana Ball (Plates XXTIT, XXVIII, XXX; fig. 1) Norvellina apachana Ball, E. D., Fla. Ent., XV, 1, p. 4, 1931.

The original description is as follows:

“Resembling bicolorata, but smaller and with obscure markings throughout. Size and form of nevada, but less heavily marked. Pronotum, scutellum and an oblique spot on apex of elytra heavily irrorate with brown, the saddle very obscure. Length, 4-4.5 mm.

Vertex shorter than in sawcia which it otherwise resembles, twice wider than long, scarcely longer on middle than against eye. Front narrower and less in- flated than in saucza, much less than in bicolorata. Female segment rounding posteriorly, deeply triangularly excavated with a broad straplike projection. Male plates long, triangular as in saucia.

Color. Face and vertex pale creamy, the latter with three to five irregular irrorations on posterior half. Pronotum ivory, heavily and irregularly irrorate with brown. Scutellum almost solid brown with seven white spots around the margin. Elytra with a very obscure saddle marking of pale brown, a brown wash over the ivory areas, a dark spot some distance back of the cross nervure on either side and a third one at apex of clavus. The vermiculations become more definite before the long oblique apical spot.

Holotype female, allotype male, and seven paratypes, Granite Dell, Ariz., August 17, 1929, and six paratypes Glenn Oaks, Ariz., October 9, 1929, all taken by the writer.”

Genitalia. Last ventral segment of female as above. Male valve obtusely angulate, less than one-half as long at center as preceding segment; male plates converging to narrow point, over twice as long as greatest width. Aedeagus in lateral view stout and curved dor- sally, apex rounded to inner margin, with a pair of ventrolateral processes arising basally, closely appressed to shaft except at spear- like apices ending slightly before apex of shaft. Pygofer about twice as long as median width, with dorsally directed free portion of hook about as long as width of pigmented tip of pygofer.

Four male specimens are at hand from the type locality as well as several specimens from Yavapai county, Arizona; Chiricahua Moun- tains, Arizona; Las Cruces, Vaughn, Belen and Hope, N. Mex.; col- lected from “Apache plume” (Fallugis paradoxa) from which it derives its name.

Norvellina bicolorata (Ball) (Plates XXIII, XXVII, XXIX; fig. 2) Eutettix. bicolorata Ball, E. D., Can. Ent., XXVII, 1, p. 212, 1905.

Externally distinct, large forms. Aedeagus resembling N. colwm- biana (Ball), but more slender and with more pronounced bifid beak on inner apex. Length, 6.5 to 6.75 mm.; width, 2 mm.

Linpsay: Tur Genus NorvELLINA VET.

Vertex broadly rounding, slightly more produced at center than next eyes; highly arched behind transverse depression, shelflike be- fore, especially in females. Front inflated, meeting plane of vertex anterior to transverse depression at right angle or more; margin distinct, especially in females. Pronotum highly arched.

Color. Fuscous, and greenish-yellow. Vertex pale cream to tawny, with four small, dark spots on anterior margin between ocelli, one spot behind each ocellus, and with large more or less reticulate areas of fuscous in center of each half of posterior disc, usually with vermiculate extension fusing with spot behind ocellus. Pronotum heavily vermiculate or reticulate with fuscous, darker along anterior margin, especially touching each eye, and omitting numerous light areas and spots. Scutellum mostly brown to retic- ulate fuscous, with hght triangular areas at each end of transverse suture. Elytra greenish-yellow to apex of clavus; posterior to clavus opaque white, heavily vermiculate with contrasting fuscous. Apical portion solidly fuscous with exception of one or two lhght spots in second or third apical cell and narrow hyaline margin.

Genitalia. Last ventral segment of female over twice as long as preceding, lateral margins rounded on posterior half, shallowly sinuate each side of the notched, slightly produced center. Male valve short, rounding posterior margin only slightly produced be- yond preceding segment. Plates triangular, twice longer than broad. Aedeagus in lateral view thick at base, but with long, slender, dorsally curved shaft; apex avicephaliform with recurved bifid beak on inner margin, and a pair of ventrolateral processes arising basally and extending to near apex. Pygofer about one-third longer than median width, hook directed dorsally, narrow, slightly curved on inner margin and free portion nearly twice as long as apical width of pigmented area of pygofer.

“Described from one female from Castle Hot Springs, Ariz., H. 8. Barber collector (U.S. N. M. Collection) and four speci- mens taken by the author at Richfield, Utah.”

Apparently Doctor Ball had both N. bicolorata and its smaller variety at hand when he wrote the original description. Therefore one of the specimens from Richfield, Utah, in the collection of Doctor Ball, is here designated Lectotype. Numerous specimens are at hand from the type locality, taken on Ephedra, and are dis- tinct from the Arizona and California forms. Four specimens col- lected at Las Vegas, Nev. (Nov. 15, 1934, Davis and Dorst), in

the collection of E. W. Davis proved to contain two of this species and two of the smaller variety. Otherwise they are apparently definitely restricted in habitat.

Norvellina bicolorata var. inflata Lindsay (Plates XXIII, XXVII, XXIX; fig. 8)

Jour. Kan. Ent. Soc., Vol. 11, p. 113, 1938

Closely resembling N. bicolorata (Ball), but readily separated by shorter length, extremely inflated front, usually fumate or whit- ish eyes, and normally immaculate, lemon-yellow elytra anterior to apex of clavus. Fuscous markings decidedly lighter and more sparse. Length, 5 to 5.5 mm., width, about 1.5 mm.

Vertex inflated, broadly rounding, slightly more produced at center than next eyes; highly arched behind transverse depression. Front bulbously inflated meeting plane of vertex at obtuse angle. Pronotum highly arched to horizontal scutellum.

Color. Vertex pale ivory to whitish, with two median spots of fuscous on anterior margin and a similar spot behind each ocellus; each half of dise posterior to transverse depression centered with a triangle of fuscous vermiculations. Front above matching back- ground of vertex. Pronotum fuscous vermiculate with fumate to white background; the fuscous darker on anterior margin, es- pecially touching eyes, and omitting irregularly patches of light background. Scutellum mostly light brown with white lateral margins except for fuscous spots on the margin posterior to trans- verse suture. Elytra anterior to apex of clavus usually bright lemon-yellow, sometimes faded to whitish; beyond clavus whitish, nearly hyaline, with fuscous veins and sparse vermiculations the extreme apical portion solidly fuscous except for hyaline margin and one round spot on tip of third apical cell.

Genitalia. As in N. bicolorata (Ball) except for slightly more slender aedeagus, apical beak shorter and less recurved and base not so heavy.

Holotype male, allotype female, White Sands, N. Mex., June 30, 1932, R. H. Beamer. Numerous paratypes from the following localities: Grand Canyon, Ariz.; Las Cruces, N.

Norvellina seminuda (Say) (Plates XXIII, XXVII, XXIX; fig. 4)

Jassus seminudus Say, Ac. Nat’l. Se. Phil., 6, p. 307, 1831.

Closely resembling N. scitula Ball, but with markings on vertex and pronotum light tawny and with basal elytra not distinctly vermiculate. Females easily distinguished by nearly truncate last ventral segment, with tapered, slightly bilobed median projection notched at either side.

Vertex rounding, only slightly longer at center than next the eyes; from lateral view arched back of transverse depression. Front at normal angle, margin definite. Pronotum arched, anterior margin more produced than posterior.

Color. Vertex light ivory with four pale yellowish spots on anterior margin and a similar spot behind each ocellus; posterior dise faintly marked with yellowish or fumate spots. Pronotum, ex- cept anterior and lateral margins, lightly fumose. Scutellum with yellow to tawny lateral corners and apical portion, except for ex- treme light tipped apex. Elytra with suggestion of transverse markings on bases, with completely transverse saddle of cinnamon brown extending from midclavus to mesal margin to apex of clavus and partially edged with fuscous. Apex of elytra lightly vermiculate with brown, mostly in third and fourth apical cells.

Genitalia. Last ventral segment of female nearly truncate pos- teriorly, with slightly bifid median straps notched at either side to a depth about one-half length of strap. Male valve roundingly produced at center to about three-fourths length of preceding seg- ment; plates long-triangular. Styles on distal third narrowed, curv- ing slightly laterad, pointed on outer margins at apices. Aedeagus thickened basally, with dorsally curved shaft tapered to apex where it is slightly enlarged, and with a pair of ventrolateral processes arising near base and tapering to points as long as shaft. Pygofer broad with slightly in-eurved hook arising on ventral posterior margin, free on outer two-thirds, and extending dorsally nearly the width of the pygofer.

Neotype male, allotype female, Douglas county, Kansas, Septem- ber, 1923, W. Robinson, described above, are here designated. Numerous specimens are at hand from the following states: Florida, Alabama, Mississippi, Louisiana, Texas, Kansas, Missouri, Ne- braska, Iowa, Minnesota, Ohio, South Carolina, New Hampshire, Connecticut, New Jersey, and New York.

180 THE UNIVERSITY SCIENCE BULLETIN

Norvellina scitula (Ball) (Plates XXIII, XXVII, XXIX; fig. 5) Eutettiz scitula Ball, E. D., Can. Ent., XX XIII, p. 47, 1901. The original description is as follows: “Resembling seminuda, but with the pronotum darkened up. Length, 5.5

mm.; width, 1.5 mm.

Vertex almost parallel margined, twice wider than long, half the length of the pronotum, strongly depressed. Front rather flat, its length and breadth about equal. Pronotum long, its lateral angles distinct, dise but feebly convex.

Color. Vertex pale creamy yellow, six pale fulvous spots along the anterior margin, sometimes a pair of spots near eyes on basal half. Pronotum dull white, coarsely irrorate with dark fulvous, omitting the pale yellow anterior margin. Traces of three pale stripes. Scutellum pale, the fine dark-brown irrorations usually heaviest in a spot just within the basal angles on either side, and another behind the transverse suture. Three spots in a triangle on apical half ivory white; posterior dise light. Elytra milky white, a few coarse, brown irrorations along the humeral and sutural margins before the middle, a transverse band behind the middle as in semiznuda, but darker brown, and some irregular infuscations towards apex. Face and below pale yellow, pale fuscous ares on front.

Genitalia. Ultimate ventral segment of female twice the length of penulti- mate, the posterior margin slightly rounding, with two small, roundingly angular, median teeth; male valve obtusely triangular; plates long triangular, their apices attenuate, infuscate.

Described from numerous specimens from Fort Collins, Pueblo, Salida ana Grand Junction, Colo. This species is most closely related to seminuda, but the genitalia and pronotal band will at once distinguish it.”

Genitalia. As above, with aedeagus in lateral view stout, curved dorsally and tapering to a slightly flared, membranous apex, with a pair of ventrolateral processes arising near base and extending to apex, curved toward shaft on tips. Pygofer tapering toward a slender, shightly curved hook apically attached on basal third and free portion extending backward and dorsally at about a forty-five degree angle with the plane of the ventral margin.

Lectotype male, allotype female, Fort Collins, Colo., July 29, 1898, here designated and in the Colorado State Agricultural College collection. Other cotype specimens are at hand as well as numerous specimens from the west and southwest. This species apparently replaces N. seminuda (Say) in the states west of Texas and Kansas.

Norvellina pullata (Ball) (Plates XXIII, XXVII, XXIX; fig. 6) Eutettiz pullata Ball, E. D., Can. Ent., XX XIII, p. 48, 1901.

The original description follows: “Form and general appearance of scitula, but darker, approaching pere- legantis in shade, but lacking the definite pattern of that species. Length, 5.5

mm.; width, 1.5 mm. Vertex two and one-half times wider than long, half the length of the pro-

notum, transverse depression very shallow, front broad and flat. Pronotum rather flat, scutellum transversely depressed, the apex swollen, elevated.

Colour. Vertex white or pale yellow, a narrow fuscous line just in front of eyes, in front of which are four dots, and behind which are three large irregular, sometimes confluent, irrorate patches. Pronotum light, coarsely and somewhat sparsely irrorate with brown. Scutellum with a brownish fuscous patch just within each corner, disc pale or orange-yellow. Elytral pattern as in scitula, but broader and darker; clavus entirely reticulated except for two transverse bands, one at base and a broader, interrupted one before the middle, the white area of the cortum with a few dots or reticulations.

Genitalia. Ultimate ventral segment of female three times the length of the penultimate, the posterior margin broadly rounding, the median fourth triangularly excavated, the apex of this excavation broad, rounding or bidentate; male genitalia as in scitula, valve obtuse, plates long triangular, the margins straight, tips attenuate.

Described from eighteen specimens from Manitou (Van Duzee), and five from Colorado Springs and Salida, Colo., by the author.”

Genitalia. In addition to above, distal portion of styles stout, about one-half as long as in seminuda, and with inner margin at apex rounding. Aedeagus in lateral view short, shaft about one and one-half length of base, directed dorsally, membranous apex blunt, rounding on outer margin; ventrolateral processes arising near base and extending about length of shaft with tips acuminate, incurved. Pigmented pygofer narrow on posterior third, thickened hook broadly attached to posterior margin, free portion tapering dorsally at least length of attached base.

Lectotype female, Colorado Springs, August 7, allotype male, Salida, Colo., July 24, 1900, in the collection of Doctor Ball here designated and representing the two cotypes examined by the author. Other specimens in Doctor Ball’s collection also examined were: One male, Richfield, Utah, August 7, 1904, described above; one male, Huachuca Mts., Arizona, Collected on pine; and two fe- males and one male, Williamson Valley, Ariz. One female from Silver City, N. Mex., in the Snow Entomological Collection, and one female, Richfield, Utah, September 2, 1930, Willow Patch, in the collection of E. W. Davis, were also examined.

Norvellina chenopodii (Osborn) (Plates XXIV, XXVII, XXIX; fig. 7) Eutettix chenopodii Osb., H., Ohio Jl. Se., XXIII, p. 161, 1923.

This is one of the most widely distributed species of the Norvel- lina, and, next to N. seminuda (Say), has been known longer than other forms in the genus, although prior to its description by Osborn

it was confused with Phlepsius strobi Fitch. The original descrip- tion follows:

“Similar to Phlepsius strobi Fitch, but with the vertex short, rounded to front and the elytral picture consisting of two whitish bands instead of three. Length, female, 5.5; male, 4.5.

Head slightly wider than pronotum; vertex short rounded in front with a shallow transverse depression, scarcely longer at middle than next the eye, ob- tusely angulate to front; front slightly longer than broad, clypeus short, scarcely widened at tip; lorae elongate, the tip reaching border of cheek. Pro- notum more than twice as long as vertex, hind border concave.

Color, light fulvus irrorate with light yellow or whitish. Elytra brown, with two white bands, the forward one oblique and extending from tip of scutellum to costa at middle, the hinder one crossing the anteapical cells.

Genitalia. Female last ventral segment twice as long as preceding, hind border rounded with a notched lobe at the middle. Male valve rounded be- hind, plates triangular, tips acute.

This is a common species throughout the eastern U. 8S. and its nymph is found on lambs quarter (Chenopodium) where it produces purple spots that agree in color with the nymph. The description is from specimens collected in Iowa and Ohio, but records under the name of strobi carry its distribution from Maine to Utah and South to North Carolina and Texas.

The nomenclature of this species presents a peculiar puzzle as it was actu- ally described by Van Duzee under the name strobi which, as.shown above, must apply to a different species and the name would be preoccupied in Phlepsius. Ball, however, described the species, having placed it in Kutettix in which genus the name strobz has not been used for any other species. How- ever, this was simply a transfer of the Van Duzee misnomer and as the species occurs on Chenopodium and not on Strobus it will avoid confusion to give it a new name and preferably one which indicated its restricted food habit.

Type and paratype specimens of above description in author’s collection.”

Genitalia. In addition to the above, styles short, narrowed distal fourth stout, curving laterad, inner margin convex to apex at outer margin. Aedeagus in lateral view directed dorsally, curved most sharply near base and with apex bent inward, membranous and slightly enlarged; two ventrolateral processes arising near base and extending along shaft to near apex, tips bent inwardly correspond- ing to apical bend in shaft, but definitely shorter. Pygofer twice longer than median width, posterior margin diagonal and consisting of a stout, straight, dorsally directed hook, free on outer third.

Norvellina helenae Ball (Plates XXIV, XXVII, XXIX; fig. 8) Norvellina helenae Ball, E. D., Fla. Ent. XV, p. 3, 1931.

The original description follows:

“Resembling chenopodii Osb., but much smaller with the much heavier vermiculations somewhat obscuring the saddle. Length, 4-4.5 mm.

Vertex proportionally longer than in chenopodii, twice wider than long, slightly longer on middle than against’eye. Elytra reticulate throughout so that the lighter areas bounding the saddle are coarsely reticulate instead of ivory as in chenopodii. Female segment with a broad angular median notch in the apex of which arises a straplike process as long as wide and slightly bifid at apex. In chenopodii the margin is only faintly indented either side the strap. Color brownish fulvous with a fulvous vertex and scutellum, a brown saddle set off by semireticulate ivory areas. Face and below sordid fulvous.

Holotype female and allotype male Sanford, Florida, June 17, 1926, and six paratypes from the same place at various dates all collected by W. E. Stone and the writer near Lake Helen. The writer has material from Florida, Texas, Missouri and Kentucky and is inclined to believe that this small species re- places chenopodii throughout the entire cotton belt.”

Genitalia. As above, styles shorter than chenopodi and angulate on inner margin to apex on outer margin. Aedeagus in lateral view curving dorsally and ending apically in a short membranous inward beak; with a pair of ventrolateral processes arising near base and extending length of shaft, distal one-fifth twisted half around and flaring slightly in dorsal view. Pygofer about twice longer than median width, pigmented portion narrowed posteriorly toward ven- tral margin and ending in a slightly curved, dorsally directed hook, usually more slender but varying to the form of chenopodu.

Numerous specimens are at hand from the following states: Kan- sas, Texas, Missouri, Mississippi, Alabama, Florida, Virginia, New Mexico, and Colorado, and one specimen each from Iowa and South Dakota.

The above two species appear to be quite distinct at the extremes of their distribution, e. g., N. chenopodi in northern United States and N. helenae in Florida and southeastern United States, and are markedly different in size, shape of vertex, shape of scutellum, de- eree of coloration and shape of aedeagus and last ventral segment of female. However, some specimens taken in Kansas and vicinity

184 Tue UNIvERSITY SCIENCE BULLETIN

show a definite convergence of characters, making them nearly indistinguishable externally, with even the genitalia of the males in near agreement in one or two structures. Typically, N. chenopodii is characterized by a curved aedeagus, in lateral view, a membra- nous apex bluntly rounded and with lateral processes lacking ap- proximately a tenth of being as long as aedeagus, the tips of proc- esses fitting closely to shaft. In N. helenae the aedeagus is simi- larly curved, but instead of being smoothly rounded at apex the tip has a short inward hook. In addition the lateral processes are as long as the aedeagus and instead of fitting snugly along shaft at tip the apical one-fifth flares outward. In general the genitalia of N. helenae are smaller than N. chenopodu and the styles compara- tively shorter and with more angulate apices.

Specimens from Kansas and vicinity are usually distinct, but occasionally the two appear to merge in one or more characters. For example, the typically deep notch in the last ventral segment of N. helenae from which arises a slightly bifid strap is occasionally shortened to approach the shallow sinuations on either side of the median notch typical of N. chenopodii. Female specimens other- wise typically N. chenopodii sometimes have truncate ultimate seg- ments closely approaching N. helenae in structure. In the males the commonest resemblance is found when the general appearance of styles and aedeagus are typically as in N. helenae, but the lateral processes of the aedeagus shortened as in N. chenopodw. In such cases the predominance of characters, both external and internal, have been those of N. helenae, so that usually the males have been classified as N. helenae, atypical. However, atypical females seem more numerous.

Two male specimens are at hand indicating new distribution records for N. helenae, one in the collection of E. W. Davis labeled Ames, Iowa, June 21, 1931, H. H. Knight, and a second in the Snow Entomological Collection labeled Redfield, 8. Dak., July 20, 1937, R. H. Beamer.

Norvellina mildredae (Ball)

(Plates XXIV, XXVII, XXIX; fig. 11) Eutettix mildredae, Ball, E. D., Can. Ent., XX XIII, p. 45, 1901.

Closely resembling N. perelegantis (Ball), but easily distinguished by light-colored apical third of scutellum, as well as male pygofer hook. Females usually about 6.25 mm. in length and 2 mm. wide; males 5.5 mm. long and 1.75 mm. wide. The original description follows:

Linpsay: Tur Genus NorvELLINA 187

“Form and general appearance of pulchella; colour pattern of scaber, but with extra markings, and different colours on pronotum and elytra. Length, 5.5 mm.; width, 1.75 mm.

Vertex slightly angularly rounded, transversely depressed before the apex; front as in scaber, the margin between front and vertex more strongly pro- duced. Pronotum slightly angularly rounding anteriorly, much more so than in scaber; lateral angles scarcely apparent, rounding from eye; pronotum and scutellum convex, elevated.

Colour. Vertex orange-yellow, paler at base; scutellum orange, the basal angles and the margins at apex irrorate with fuscous. Pronotum dirty white, some black spots next the eyes; disc irrorate, pale olive-brown, omitting an oval spot on the posterior disc on either side and the median line. Elytra milk white, with black margined areas of olive-brown, as follows: All of clavus except a semicircular spot at base and another at middle of claval suture; an oblique band on corium, beyond this spot narrowing to the costa. There are three pairs of black spots along the sutural margin of clavus, the apical pair largest. The claval suture between the white spots, and the anterior and costal margins of the oblique band, heavily black. Inner apical cells and a few spots on costa irrorate with black. Face orange, a black spot on outer angle of either lora. Below pale yellow and fuscous.

Genitalia. Ultimate ventral segment of the female about twice the length of the penultimate, the posterior margin broadly, slightly rounding, the median third produced in two rounding lobes; the notch between them not as deep as their length, the lobes usually black; male valve obtusely triangular, a httle over half the length of the ultimate segment; plates long triangular, about three times the length of the valve, the apex attentuate, filamentous, together with the margin clothed with long silky hairs.

Described from three females from Colorado Springs, taken by the author, and fourteen examples of both sexes from Manitou, collected by Professor Van Duzee. This is one of the prettiest Jassids that I have ever seen, and I take pleasure in naming it after my wife, whose careful drawings will add much to the value of my future synoptic work.”

Genitalia. As above with styles on distal portion median long, shightly convex on inner margin and tapering to an apical point near outer margin. Aedeagus in lateral view long, slender and terminat- ing apically in slightly narrowed head; two ventrolateral processes arising near base and extending about length of shaft, apices sharp and bent toward shaft. Pygofer broad with long, stout, rather straight hook arising on posterior ventral margin and extending dor- sally and backward at about a sixty degree angle with the plane of the ventral margin.

Lectotype female, Colorado Springs, here designated from the cotype series in Doctor Ball’s collection. One cotype from Colorado Springs, in the collection of the Colorado State Agricultural College, examined as well as numerous specimens from Poudre Canyon, Colo.; Silver City, Las Vegas, Tucumcari, and Luna, N.

Norvellina mildredae var. minuta Lindsay (Plates XXIV, XXVIII, XXIX; fig. 12) Jour. Kan. Ent. Soc., Vol. 11, p. 114, 1938

Closely resembling mildredae in all respects except size and distri- bution. Small specimens, female 4.75 mm. long and male 4 mm.

Genitalia. Styles and aedeagus shaped as in mildredae, but about half as large. Pygofer about two-thirds as large as mildredae.

Holotype male, allotype female, and one male paratype from Ozona, Tex., July 9, 1936, R. H. Beamer. These miniature mildredae are so strikingly smaller than the true species as to warrant varietal ranking. In addition their habitat on the open, arid plains indicates that they are probably from a different host than the mountain mildredae taken on red cedar and, according to Ball, found only in sheltered situations.

Norvellina scaber (Osb. and Ball) (Plates XXV, XXVIII, XXIX; fig. 13) Eutettix scaber Osb. and Ball, Proc. Day. Ac. Se., VII, p. 96, 1898.

This large, robust species, although taken in well-collected terri- tory, 1s represented only by four cotypes and one specimen, and therefore seems a rare form. The original description follows:

“Form of (Hutettix) lurida, dark, fulvous-brown above, with a large angular area on the outer base of the elytra. Length, female, 6.5mm.; male, 6mm. Width, 1.75 mm.

Vertex parallel-margined, over three times wider than long, transversely de- pressed back of the rounding margin, front broad, wedge-shaped, longer than in lurida, the clypeus hardly widened at the tip, genae with the outer margin rounding. Pronotum broad, convex, highest behind, the humeral margin straight, parallel with the margin of the scutellum. Elytra broad, only slightly overlapping behind, nervures indistinct.

Color. The vertex reddish-brown anteriorly with five white spots conflu- ent with the margin, posteriorly with two white spots just before the margin slightly nearer each other than the eyes, face light yellow, a black spot against the outer margin of the lorae, pronotum and scutellum chestnut, finely irro- rate, two white spots on the scutellum against the ends of the transverse de- pression and another at tip; elytra heavily irrorate, almost clouded with dark chestnut, except for the outer margin of the basal part of the clavus the entire basal half of the corium, and an indistinct transverse band just before tip strongest on the costal margin. The basal part of corium in hyaline yellowish, oblique behind, bordered above by a narrow white line on the margin of the clavus and extending forward across the lateral margin of the pronotum to the corner of the eye; below yellowish.

Genitalia. Female, ultimate ventral segment moderately long, lateral angles rounding, posterior margin slightly produced and feebly notched in the middle, pygofers much longer than in lurida, obscure yellowish with brown spots; male

Linpsay: THE Genus NorvELLINA 189

valve rounding, plates triangular, twice the length of the valve, their margins clothed with long hairs.

Described from three females and one male, collected at Ames, Iowa; two of them swept from white oak.”

Genitalia. As above, with distally narrowed portion of styles moderately long and bluntly pointed on apices. Aedeagus in lateral view curved sharply near base and extending dorsally with swollen hump on outer curve of shaft just prior to apex with short inward beak; a pair of ventrolateral processes arising basally and extending to near apex of shaft, curved at tip correspondingly with hump on shaft. Pygofer large and broad, not much longer than median width, and with hook arising on posterior-ventral corner inside the pygofer plate and projecting dorsally.

Doctor Ball (Proc. Dav. Ac. Sc., XII, p. 27, 1907) later consid- ered this species as a variety of pulchella, and although there is a resemblance in pattern, all other characteristics indicate a distinct species. Curiously enough the internal genitalia here are about the size of most of the smaller species in the genus.

Lectotype male, allotype female, Ames, Iowa, here designated and in the Iowa State College collection. Two cotypes and one other specimen, all females, in the collection of Doctor Ball.

Norvellina flavida Lindsay (Plates XXV, XXVIII, XXIX; fig. 14) Jour. Kan. Ent. Soc., Vol. 11, p. 114, 1938

Closely resembling N. pulchella (Baker), but easily distinguished by the broadly suffused, canary yellow corium anterior to costal plaque, vertex not so produced and more rounding, with generally lighter markings on dise. Pygofer hook vestigial. Length of fe- male, about 5 mm.; male, 4.75 mm.

Vertex scarcely produced at center in males, more distinctly in females with definite margin; only slightly arched behind transverse depression. Pronotum slightly arched in lateral view. Elytra long, overlapping.

Color. Front yellow streaked with brown, yellow extending slightly over margin of vertex. Vertex with four brown spots near anterior margin with a similar spot behind each ocellus usually con- nected to tawny-brown pattern behind transverse depression. Pro- notum fuscous, omitting a sprinkling of light areas and irregular, yellowish lateral margins. Scutellum about like pronotum, slightly lighter. Elytra with median pattern composed of brown back- ground covered with fuscous vermiculations extending over most of

clavus to apex, and spreading laterally to margin at costal plaque, omitting three pairs of small, round semihyaline aereoles on mesal margin; elytron distal to clavus with lighter continuation of pattern to apex, mostly in third and fourth apical cells.

Genitalia. Female ultimate segment more than twice length of preceding, rounding posteriorly from lateral margins, slightly pro- duced at center with median notch sinuate either side. Male plates long-triangular, acuminate at apices. Styles longer than usually on distally narrowed portion, rounding on inner margin. Aedeagus in lateral view sharply curved dorsally, tapering on distal half to dorsoventrally flared apex, about four times broader than shaft next apex; a pair of ventrolateral processes arising at base and tapering to a little past apex of shaft, more curved at tip.

With pattern and color as in NV. scaber (Ball), but smaller, not so plump in appearance. Length of female, about 5 mm., male, 4.5 mm. Distinguished from all other species in the genus by two long, armlike, posteriorly directed hooks arising on each of the involute ventral margins of the pygofer.

Vertex short, broadly rounding, only slightly more produced at center than next eyes; transverse depression shallow, dise only slightly arched posteriorly. Pronotum slightly arched in lateral view, anterior margin more produced than posterior.

Color. Vertex yellowish on margin with four extensions of brown coloring on dise slightly anterior to transverse depression; reddish- brown coloring on posterior disc and pronotum, except for ivory

lateral margins omitting numerous irregular whitish spots. Scutel- lum similarly colored with three marginal white spots forming apical triangle, usually with four distinct spots on anterior disc and numer- ous small spots. Elytra with heavily vermiculate median pattern covering most of clavus to apex and extending laterally from distal third of clavus to costal plaque, with three hyaline equidistant spots on mesal margin, basal corium mostly hyaline to fumose; elytra beyond clavus coarsely vermiculate, heavier on third and fourth apical cells.

Genitalia. Female ultimate segment twice longer than preceding, rounding from sides to centrally produced posterior margin with small median tooth slightly bifid and notched at either side. Male valve obtusely angular, about three-fourths length of preceding seg- ment, plates long-triangular, not attenuate. Styles on narrowed distal portion moderately long, extending diagonally laterad and slightly knobbed on apices. Aedeagus in lateral view short, shaft nearly straight, roughly toothed on outer margin with a pair of lat- eral processes arising near base and extending about three-fourths length of shaft. Pygofer broad, only slightly longer than median width, rounding posteriorly with long, armlike process arising on involute ventral margin and extending posteriorly nearly half of length beyond posterior pygofer.

Numerous specimens are at hand from Patagonia, Tucson, Mescal, Hereford, and Alamo, Ariz., and Hot Springs, N. Mex. As stated by Doctor Ball (Proc. Dav. Ac. Sc., XT; jp. 52, 1907), this is a southern form and Baker’s specimens from Fort Collins probably belong to the saucia group, since they are qualified in the original description.

Face and below creamy. Pronotum ivory, mottled with olive and brown, omitting the lateral and most of the anterior margin; two definite black spots behind the inner angle of either eye and two irregular ones nearer the median line. Scutellum creamy, the lateral angles olive brown. Elytra ivory subhyaline, with an olive-brown saddle as in saucia, but lighter or wanting along the sutures, and with three definite, dark points extending almost to the claval suture, apical cloud reduced to spots on third and fourth nervures.

Genitalia of male as in sauwcza.

Described from two males from Wenatchee, Washington, collected by the writer. From saucia this species can be separated by the definite black spots on the pronotum, from perelegantis by the structure of head and pronotum.”

The above description of color modified to fumose, with a light- brown saddle irrorate with brown, since the majority of specimens at hand are darker than the two cotypes. The females closely re- semble the males, slightly larger, 6.75 mm. long.

Genitalia. Ultimate segment of female about three times longer than preceding, rounding gently at sides, nearly truncate on posterior margin with median notch. Posterior margin, except at center, widely membranous. Male valve short, obtuse; plates moderately long-triangular, nearly acuminate at apices. Aedeagus in lateral view long, curving dorsally more sharply at a point about one-third length of shaft, apex rounding on outer margin with short inward beak; a pair of ventrolateral processes arising basally and extending broadly to near apices where they narrow to a point even with apex of shaft. Pygofer broad, little longer than median width; a thick- ened hook attached along posterior border, free portion about one- third total length and directed dorsally.

Lectotype male, Wenatchee, Wash., August 18, 1912, designated in the collection of Doctor Ball. Allotype female, Pasco, Wash., July 8, 1935, Oman, here designated and in the U.S. N. M. Three males and one additional female from the latter locality have been examined.

Vertex obtusely angulate in females, distinctly more produced at center than next eyes; males more rounding.

Linpsay: THE Genus NorvELLINA 193

Color. Vertex with four irregular brown spots near anterior mar- gin and one behind each ocellus on ivory to cream-colored back- ground; discs posterior to transverse depression usually vermiculate with brown.

Scutellum tawny to brown omitting numerous light spots. Elytra as above, apices sparsely vermiculate.

Genitalia. Ultimate female segment twice longer than preceding, sloping inward on posterior half of lateral margins; posterior mar- gin truncate with short, slightly bifid, wedge-shaped median tooth, shallowly notched at either side. Male valve obtuse, over half length of preceding segment; plates triangular, about twice as long as basal width, slightly attenuate at apices. Aedeagus in lateral view short, curved dorsally, rounding on outer margin near apex, slightly constricted to apical head bluntly pointed on inner margin; a pair of ventrolateral processes.

Elytra with median pattern as in saucia, but darker, composed of tawny-brown background heavily irrorate with mahogany; distal portion sparsely vermiculate with fuscous over anteapical cells, more heavily on third and fourth apical cells.

Genitalia. Ultimate female segment about twice length of pre- ceding, posterior margin gently rounding with a very short tooth either side of a shallow median notch, slightly sinuate at either side. Male valve obtuse; plates long-triangular, nearly acuminate on distal half. Aedeagus in lateral view stout, curved dorsally on basal half, distal half nearly straight and ending in bluntly rounded apex; two slender ventrolateral processes arising at base and extending slightly beyond apex, mostly free of shaft. Pygofer broad, sloping distally toward dorsally extended hook arising on posterior margin and with free portion about equal to posterior width of pygofer.

Holotype male, allotype female, Pasadena, Cal., July 31, 1912, E. D. Ball; one male paratype, Pasadena, Cal., April 23, 1908; four female paratypes, Ontario, Cal., June 14, 1931, E. D. Ball. Types and paratypes in Doctor Ball’s collection and paratypes in Snow Entomological Collection. Other specimens are at hand from Three Rivers, Pine Valley, San Jacinto Mts., Campo, San Gabriel Canyon, and Colfax, Cal., and Cisco, Utah, but all showing slight variations and for this reason are not included in the paratype series. The ap- parent tendency of this form to vary in shape of and markings on vertex, while genital structures remain constant, accounts for its spe- cific name.

Norvellina saucia (Ball) (Plates XXV, XXVIII, XXX; fig. 19)

Eutettix saucia Ball, E. D., Can. Ent. XX XIII, p. 46, 1901.

The original description follows:

“Form and general appearance of scaber, smaller and paler, the vertex mostly pale. Length, 4.5mm.; width, 1.5mm.

Vertex longer, narrower and more angulated than in scaber; face narrower above, longer than its basal width, rounding to the clypeus. The pronotum broadly and evenly rounding in front, truncate behind, almost twice the length

of the vertex.

Linpsay: THe Genus NorveLLINA 195

Colour. Vertex pale yellow, six minute points on anterior margin and three irregular irrorate patches on posterior margin brownish fuscous. Pronotum white, coarsely irrorate with dull brown except a narrow lateral margin and traces of three pale lines. Scutellum more finely irrorate, three ivory white points in a triangle beyond the transverse line. Elytra milky white, closely and finely irrorate with dull brown, as follows: All of clavus except a narrow strip along basal two-thirds of claval suture, once or twice interrupted and broadened at the end; a rather narrow oblique strip across corium beyond this and some irregular markings towards the apex, which form two definite spots on the costa. Two pairs of pale spots along the sutural margin of clavus. Fale pale yellow, below, pale and fuscous.

Genitalia. Ultimate ventral segment of the female nearly twice longer than penultimate, the posterior margin nearly truncate from the rounding angles, with two triangular, slightly protruding median teeth; male valve very ob- tusely triangular; plates long triangular, their apices attenuate, black clothed with fine silky hair.

Described from a pair from Denver, a male from Fort Collins, Colo., and another from Tucson, Ariz. This species is closely allied to scaber, from which the longer vertex, smaller form, lighter color and absence of distinct band on vertex will easily distinguish it.”

Gemtalia. As above, but in addition with aedeagus in lateral view long and evenly curved dorsally, ending apically with an inwardly directed, fingerlike process; two ventrolateral processes arising near base and extending broadly to near apex of shaft. Pygofer a little longer than median width, sloping distally to a stout, nearly straight hook attached on posterior margin and extending dorsally, free on distal third.

Lectotype female, allotype male, Denver, Colo., September 7, 1898, here designated, the lectotype in Doctor Ball’s collection and the allotype in the Colorado State Agricultural College collection. The remaining two cotypes have been examined and the one from Arizona proved to be N. snowi (Ball), described at a later date. Eight additional specimens are at hand: One female, Fort Collins, Colo., August 29, 1902; one male, Greeley, Colo., August 5, 1901; one female, Buena Vista, Colo., September 19, 1901; and five males, Colorado, two 2158, two 1596, and one 2121, collection of C.

Length of female, about 5 mm.; males, 4.75.

196 Tue UNIvERSITY ScIENCE BULLETIN

Vertex obtusely angulate on anterior margin; in lateral view with shallow, transverse depression and posterior dise slightly inelined. Pronotum, in lateral view, scarcely arched. Elytra moderately broad giving specimens stout appearance.

Color. Vertex pale ivory or whitish with four very small, brown dots on anterior margin and a similar dot, usually elongate, behind each ocellus; with sparse, sometimes indistinct, vermiculations back of transverse furrow. Pronotum light along lateral margins and in irregular patches on anterior margin, the remainder vermiculate with brown, distinctly or lightly, usually appearing trilineate longi- tudinally with fumose white. Elytra as in saucia, but darker, usually fringed with irregular fuscous border.

Genitalia. Ultimate female segment twice length of preceding, rounding on posterior margin with a distinct median notch and a smaller notch on either side. Male valve obtuse, plates long- triangular, slightly attenuate. Aedeagus in lateral view much as in N. varia, but shorter and thicker, with ventrolateral process extending about one-sixth beyond apex of shaft. Pygofer a little longer than median width with a slender, straight hook broadly at- tached on posterior margin at an angle of about forty-five degrees with the extended plane of the ventral margin.

Holotype male, allotype female, one male and two female para- types, Prescott, Ariz., July 29, 1933, R. H. Beamer. Numerous other paratypes from the following localities: Prescott, Yarnell Heights, Yarnell, Superior, Oracle, Tucson, Williams, Granite Dell, Yavapai county, Congress Junction, and Glenn Oaks, Arizona; San Jacinto Mountains, Tehachapi, Orange county, Laguna Mountains, Doyle, Mojave, Chileoot, Newton, Los Angeles county, and Fresno, Cali- fornia; Silver City, New Mexico; Las Vegas, Nina, Alamo, Wells, and Glendale, Nevada; Pintura, St. George, Modena, and Granite, Utah. Types and paratypes in Snow Entomological Collection; ad- ditional paratypes in Doctor Ball’s collection and in U.S. N. M.

This species and the three preceding species make up a closely related group, which, for convenience, might be called the saucia group, since all the above species have at various times been placed in with N. saucia (Ball) due to a lack of stable and distinguishing characters. Only with the use of male genitalia is definite separa- tion possible, since external appearances intergrade promiscuously, sometimes with one combination of characters and sometimes with another, but in the main as described. In selecting types the author chose those specimens possessing the largest number of stable ex-

LinpsaYy: THe Genus NorvELLINA 197

ternal characters in hopes that the majority of specimens in this group can be thus keyed out. By far the larger number of speci- mens heretofore classified as N. saucia (Ball) belong in this latter species and suggested the specific name.

Norvellina rubida (Ball) (Plates XXVI, XXVIII, XXX; fig. 21)

Eutettiz rubida Ball, E. D., Can. Ent. XLVIII, p. 126, 1916.

The original description follows:

“Form of pannosa nearly. Shorter and broader with short apical cells. Colour and pattern of saucia nearly. Length: Female, 4mm.

Vertex and pronotum nearly flat as in pannosa. Vertex broader than in that species and equally long, the apex slightly obtusely angled. Whole mar- gin inclined to be thin and slightly upturned before the depression. Elytra very broad and short. Venation similar to saucia, except that the apical cells are only one-half as long. The central apical cell equally broad and long.

Colour red-brown and ivory. Vertex testaceous, the margins, ivory, with four large nearly quadrangular spots before the depression. Pronotum densely mottled with rusty brown, omitting the lateral margins. Scutellum rusty brown. Elytra ivory, with a dark, rusty-brown saddle of the saucza pattern, the line next the claval suture nearly straight and not dark margined, the apical cells densely clouded.

Genitalia. Female segment moderately long, nearly truncate, with a broad, short, bilobed projection.

Described from a single female taken by the writer in Logan Canyon, Utah; altitude, 6,000 feet. This is a strikingly distinct species, in the broad short form, short apical cells and long flat vertex.”

Male. Structure and coloration about the same, only slightly narrower. Length of each sex about 4mm.

Genitalia. Female as above. Male valve short, obtuse; plates long-triangular, about twice longer than basal width, not acuminate. Aedeagus in lateral view long, curved dorsally and with a blunt triangular process on inner margin at apex, nearly avicephaliform; Two ventrolateral processes arising near base and extending length of shaft, bent sharply inward to a point at apices to correspond to inward process of aedeagus. Pygofer a little longer than broad, rounding apically to a short hook on posterior margin directed dor- sally and with distal one-fourth free of attachment to pygofer.

and one female, Brighton, Utah, September 1, 1933, Davis and Dorst, have been determined by the author as this species. The two males, holotype and paratype, of N. oregona Ball (Fla. Ent., XV, p. 3, 1931), have been carefully examined, and although they are very slightly smaller in all respects they are considered by the author as synonyms of N. rubida (Ball).

Resembling N. varia n. sp., but usually a little darker on median pattern, vertex more angulate and produced at center, transverse depression indistinct, and aedeagus in lateral view broad and beak- like in appearance. Length of male, 5 mm.; female, 5.5 mm.

Vertex angulate from dorsal view, in lateral view margin rounded but distinct, with only a suggestion of a transverse furrow and sloping upward from anterior to posterior margin. Pronotum mod- erately arched in lateral view. Elytra long and narrow.

Color. Vertex mostly brown, omitting whitish to ivory areas along anterior margin and in irregular patches on disc; customary spots along anterior margin modified to more or less indistinct ex- tensions of brown pattern. Pronotum brown on median portion, shading to fuscous on lateral thirds excluding an irregular, light lateral margin and numerous light spots sometimes fused. Scutellum brown to fuscous omitting numerous light spots and a light ivory, triangular spot at each end of transverse suture. Elytra with typical saddle pattern light, margin of basal clavus along claval suture opaque white, basal corium mostly hyaline, allowing yellow wall of abdomen to show through distinctly; elytra beyond clavus semihyaline covered with fuscous vermiculations, sparse near clavus but heavier in extremes of third and fourth apical cells, omitting a hyaline area along the median margin in the fourth.

Norvellina pannosa (Ball) (Plates XXVI, XXVIII, XXX; fig. 24) Eutettix pannosa Ball, E. D., Can. Ent. XXIV, p. 12, 1902.

The original description follows:

“Resembling saucia and scaber in general appearance, smaller, darker, and with longer vertex and more generally reticulate elytra. Length: female, 4.5 mm.; male,4mm. Width: female, 1.5mm.; male, 1.25 mm.

Vertex right angled, apex blunt, three-fifths as long as its basal width, two- thirds as long as the pronotum, half longer on middle than against eye, disc slightly sloping, flat, with the apex elevated. Face retreating, forming an acute angle with the vertex, front rather broad. Elytra rather short, compressed at the apex, venation weak, irregularly reticulate, the second cross nervure some- times present.

Colour. Vertex and pronotum pale cinereous or milky, heavily and very evenly irrorate with brownish fuscous, except that the anterior margin of the vertex presents six more or less definite dark spots, and the lateral margin of the pronotum is narrowly lined with ivory white. Elytra with the inner halves resembling the pronotum in colour, the outer half on either side milk white, with more or less of brownish reticulation, especially along the costal margin. The brown area on the disc being heaviest along the margin, and shading out towards the suture, the milk-white area being continuous with that on the margin of the pronotum and including the claval suture to just before the middle, when it narrows down obliquely to one-half the former width, and be- comes obscured by the heavier reticulation toward the tip. Face closely and evenly irrorate with fuscous.

Genitalia. Female segment twice the length of the preceding posterior mar- gin, rounding with a rather broad, blunt, slightly bilobed median projection, surface of the segment depressed either side of this tooth; male valve triangu- lar, narrower than the ultimate segment, and about two-thirds its length; plates long, triangular, apices acute, three times the length of the valve.

Described from eight specimens from the National Museum collection ‘Los Angeles county, California, Coquillett collector.’”

Genitalia. In addition to the above the male styles, on narrowed distal portion, are slightly swollen near the middle of the outer mar- gin, apices blunt. Aedeagus in lateral view slender, curving dor- sally with a slightly bulbous apex; two flattened lateral processes arising near base and extending about one-fifth beyond shaft. Py- gofer relatively broad, posterior margin angulate with a slender, tapering hook slightly curved near apex arising near ventral margin and extending dorsally and back nearly the width of the posterior margin and at an angle of about forty-five degrees with the plane of the ventral margin.

Norvellina curvata Lindsay (Plates XXVI, XXVIII, XXX; fig. 25) Jour. Kan. Ent. Soc., Vol. 11, p. 121, 1938

Resembling N. pullata (Ball), but darker and with median pat- tern extending uniformly from base to apex of clavus and composed of fuscous irrorations and vermiculations. Length of male, about 5.25 mm.; female, about the same length but broader.

Vertex obtusely angulate on anterior margin, in lateral view margin definite, transverse depression shallow, disc inclined pos- teriorly. Pronotum only slightly arched in lateral view. Scutellum slightly inflated at apex. Elytra of moderate width.

Color. Vertex with whitish to fumose background upon which are four rather large, irregular, light-brown spots near anterior mar- gin and a smaller spot behind each ocellus; remainder of disc brown vermiculate over lighter background. Pronotum reticulate with brown or fuscous, omitting a whitish line on each lateral margin and numerous fumose to whitish areas on dise. Scutellum more heavily reticulate, usually with lateral corners and all but extreme apex of apical corner darker and with a roughly triangular light spot at each end of the transverse suture. Elytra with Norvellina type median pattern, composed of fuscous irrorations and vermiculations, heaviest on lateral margins .and extending to claval suture on cla- vus; elytra posterior to clavus sparsely vermiculate, heavier in apices of second and third anteapical cells and third and fourth apical cells.

Genitalia. Ultimate female segment round to angulate on lateral- posterior corners, posterior margin truncate with a slight bifid median projection. Male valve obtusely rounding; plates long- triangular, shghtly acuminate at tip. Aedeagus in lateral view long, sharply curved dorsally near middle, apex rounding on outer margin to short inward tooth on inner margin; two lateral processes arising basally and extending very nearly to apex, closely appressed to shaft.

Norvellina nevada (Ball) Eutettiz nevada Ball, E. D., Can. Ent., XLVIII, p. 126, 1916.

The original description follows:

“Form of saucia nearly, with a similar saddle. Colour of texana or a pale pannosa. Length, female, 4.6 mm.

Vertex similar to sawcza, slightly less sloping, pronotum very flat, much less arched than in saucia. Front very full, roundingly right angled with vertex. Venation as in pannosa.

Colour creamy white, mottled and washed with pale olive-brown. Vertex creamy, traces of four brown spots on anterior submargin, three large, slightly irregular mottled areas along the posterior margin, the median one nearly circular. Pronotum mottled with pale brown, omitting the lateral margins and three narrow stripes on the disc. Scutellum mottled with pale brown, with two stripes. Elytra milky with the saddle of a pale mottled brown, omitting an irregular sutural stripe. The ivory margin along the claval suture is narrow and regular as in pannosa, without the posterior enlargement, as in scitula, and without the usual distinct dark margins. The saddle extends to costa, but the apical cloud is reduced to a few reticulations. A number of strong reticulations on basal area of the corium below the saddle.

Genitalia. Female segment rather long, slightly rounding posteriorly, with a slight, rather broad strap-shaped projection, which is dark-lined back on to the segment.

Described from a single female collected at Wells, Nevada, by the writer. The short head will separate this species from pannosa, while the strongly margined saddle renders it quite distinct from saucia. Its mottled appearance suggests texana, but that species does not have a saddle.”

Color. The type of the above description is obviously faded, and from two subsequent specimens it is found that the coloring of the vertex, pronotum and scutellum is mostly brown on a cream to whitish background, while the elytra are marked as above, but with brown fuscous.

Genitalia. Female as above. Male value obtuse; plates long- triangular, slightly attenuate. Styles on narrowed distal portion rounding on inner margins to blunt apices. Aedeagus similar to N. apachana, in lateral view thickened basally curving sharply dorsally, apex rounding on outer margin and projecting bluntly in- ward on inner margin; a pair of ventrolateral processes arising basally and extending to near apex, tips bent slightly imward. Pygofer narrowed on posterior half to a stout hook arising on posterior margin and extending dorsally nearly the width of the base.

Lectotype female, Wells, Nev., July 20, 1912, E. D. Ball; allotype male, Redmond, Ore., July 12, 1927, and both in the collection of Doctor Ball. One female, Walden, Colo., August 20, 1931, R. H. Beamer, has been compared with the type by this writer and found to be essentially the same except for darker coloration, being about the color of the above male determined by Doctor Ball. Since the lectotype appears either faded or teneral it is safe to assume that this species is typically as dark as saucia.

Norvellina clarivida (Van D.) (Plates XXVI, XXVIII, XXX; fig. 27) Eutettix clarivida Van Duzee, E. P., Can. Ent., X XVI, p. 138, 1894.

The original description follows:

“Form nearly of Eutettiz seminuda. Pale greenish-yellow, anterior edge of the vertex with a distant pair of large, black spots and two brown points at the apex. Length, 4% to 5mm.

Vertex hardly one-fourth longer on the middle than next the eye, just one- half the length of the pronotum; marked with an impressed median line on the base, either side of which is the usual impressed area near the outer angle of the disc, and anteriorly is the transverse subapical depression common to this species of this genus. Front one-fourth longer than wide, clypeus scarcely expanded apically; cheeks as in seminuda. Valve of the male broad-triangular, about the length of the last ventral segment; plates about twice the length of the valve, their outer edges distinctly arquated near the base, pygofers ex- ceedings the plates, obtuse. Ultimate ventral segment of the female rather long, hind edge rounded with a short, abrupt median projection or tooth, about twice as broad as long; pygofers broad, a little surpassed by the stout oviduct.

Colour. Entire insect pale greenish-yellow, polished, paler on the head and beneath, tips of the tarsal joints embrowned, extreme apex of the rostrum black, anterior edge of the head with a round, black spot placed just above and within each ocellus, and two minute equidistant brown points between these on the apex. Mesonotum and sometimes the basal tergal segments black. Eyes brownish. Elytra subhyaline with strong yellowish servures.

Colorado. Described from two male and four female examples received from Prof. C. P. Gillette. Except in its want of ornamentation this insect is closely related to Hutettix seminuda, Say, like which it approaches Tham- notettix in many of its characters. But its broader form, the characters of the vertex and the wide front will indicate its relationship.”

Genitalia. In addition to the above the posterior margin of the ultimate female segment is sinuate either side of the slightly bifid median tooth. Aedeagus in lateral view curved dorsally with blunt, inwardly projecting apex; two ventrolateral processes arising basally and extending to near apex, tips slightly involute on inner margins. Pygofer broad posteriorly with a fragile hook arising on margin and extending dorsally slightly beyond attachment.

Norvellina texana (Ball) (Plates XXVI, XXVIII, XXX; fig. 29) Eutettix texana Ball, E. D., Proc. Dav. Ac. Se., XII, p. 52, 1907.

The original description follows:

“Rorm of strobi or seminuda, nearly, but entirely lacking their color pattern resembling albida, but pale creamy yellow, entirely covered by coarse reticula- tions of very pale rusty brown. Length: Female, 4.6mm.; male, 4.8mm.; width, 1.6mm.

Vertex nearly as in strobi, a trifle angled before, dise slightly sloping, in the same plane as pronotum, transverse depression shallow, acutely angled with the front. Elytra as in strobi, venation regular but very much obscured by the reticulations.

Color. Pale creamy yellow, coarsely and rather evenly reticulate with pale rusty brown, often wanting on the vertex. Pronotum and elytra often with a few scattered ivory white dots, face and below pale. Sometimes the reticula- tion becomes so pale as to be scarcely visible.

Genitalia. Female segment with the posterior margin truncate or slightly rounding, median fourth excavated either side of two rounding approximate lobes that equal or slightly exceed the margins. Male valve very short, ob- tuse, plates long-triangular, acutely pointed.

Habitat. Described from five females and two males from Brownsville, Texas (Snow), and Victoria, Texas (U. 8. N. M.), easily distinguished from the other pale forms by the saffron color and absence of definite pattern.”

Genitalia. In addition to the above, aedeagus in lateral view re- sembling helenae, but shorter and with inward apical hook less pro- nounced; two ventrolateral processes arising basally and extending to near apex, narrowed distally. Pygofer tapering to a stout hook on posterior margin, free portion directed dorsally and about half the apical width of pygofer.

A Revision of the Genus Listronotus: I (Curculionidae: Coleoptera) LYMAN S. HENDERSON,*

Department of Entomology, University of Kansas

Asrract: This paper is a revision of the species of the Coleopterous family Curculionidae which are now considered to belong to the genus Listronotus. The species have been given a monographic treatment. All the information available pertaining to the biology and distribution of the species has been included.

Thirty-three species have been described in the genus. L. distinguendus (Gyllenhal) has already been listed as a synonym of L. sordidus (Gyllenhal). The following ten species have been reduced to synonymy in this paper: L. obliquus LeConte, L. inaequalipennis (Boheman), L. sulcirostris LeConte, L. floridensis Blatchley, L. rudipennis Blatchley, L. latiusculus LeConte (nec Boheman), L. cribricollis LeConte, L. impressifrons LeConte, L. impressus Van Dyke, and L. leucozonatus Chittenden. One species, L. tessellatus Casey, has been reduced to a subspecies of L. oregonensis (LeConte). The treat- ment of five species, L. bagoiformis Champion, L. teretirostris (LeConte), L. gracilis LeConte, L. nevadicus LeConte, and L. punctiger LeConte, has been deferred, since these species belong to the group of species now considered to comprise the genus Hyperodes, or are very closely associated with certain groups of Hyperodes and represent intermediate species. Seven species of Listronotus are herein described as new. They are: L. ingens, L. manifestus, L. distinctus, L. insignis, L. blandus, L. blatchleyi, and L. similis.

Type material of all the species except L. sordidus (Gyllenhal), L. dis- tinguendus (Gyllenhal), L. caudatus (Say), and L. squamiger (Say) has been examined. The Say types are lost, and the Gyllenhal types are in Sweden and have not been examined.

No type species was designated for the genus when it was described. A genotype has been designated: L. caudatus (Say).

Illustrations and a key are included to assist in the determination of the species.

HENDERSON: THE GENUS LISTRONOTUS 217

INTRODUCTION

OME time ago, while looking over the Curculionidae with the intent of choosing a group of them for study, I noticed that very little had been done on the genus Listronotus since 1876, when Le- Conte’s paper on the Rhynchophora was published. There was ap- parently a great deal of confusion in the genus, and it seemed to me that a revision of the group would be a worth-while endeavor. The present problem was begun, and I was soon confronted by keys that would not work and original descriptions that were often inadequate or even inaccurate. There was general confusion in the literature and in collections, due to frequent misdeterminations caused by the close relationship of some of the species and the amount of variation within a single species.

A large number of specimens have been studied during the prepa- ration of this paper. Collections have been borrowed from various museums. Every species described in the genus has been studied. Some sort of type material, either type, cotype, or paratype, has been examined for every name proposed in the genus, except L. sordidus (Gyllenhal), L. distingwendus (Gyllenhal), and the species described by Say. An attempt has been made to study as much material as possible in order to secure all the available data on the distribution of the various species. All the available information on biology and host records has also been assembled.

By examining long series from varied localities, and by studying the variation exhibited by these specimens, a rather definite concept has been formed of what constitutes a species within this group. Most of the species of Listronotus display a great deal of variation, and therein lies the difficulty of a detailed study of the group. The statement may sound paradoxical, but I have seen two specimens belonging to different species which actually appeared to be more alike in many respects than two specimens representing extremes found within the same species. This is a rather drastic statement and demands an immediate explanation. As an example, we may find a male of L. tuberosus LeConte and a male of L. sordidus (Gyl- lenhal) which are so nearly alike that they defy separation by an in- experienced eye. After we have studied the two species for some time and have examined a large number of individuals in both of them, we begin to notice a rather characteristic appearance of each species, and then the two individuals can be readily separated. But the difference that one sees in these specimens may be very difficult to demonstrate to someone else and even more difficult to set down

218 THE UNIVERSITY SCIENCE BULLETIN

in print or incorporate into a key—it is a difference of degree rather than one of kind. Where we have come to recognize certain external differences, our conclusion is borne out by finding a difference in the genitalia of the two specimens.

Now let us take the same specimen of L. sordidus (Gyllenhal) which was, let us say, from New Jersey, and compare it with a speci- men of the same species from Louisiana. We may find a marked difference in size and color and, to a lesser degree, in certain ex- ternal morphological characters. This type of variation is the one upon which LeConte described L. obliquus. The genitalia show very little difference, if any, except in size. Now let us examine a large number of individuals from Louisiana, from New Jersey, and from several other localities. We soon find a multitude of intermediate forms which tie the two extremes together, and if we were to con- tinue to regard L. obliquus LeConte as a valid species we would have to find names for a large number of other variations. What we really have is one species exhibiting a wide range of variation.

This rather detailed discussion has been given purposely to illus- trate some of the problems involved in this study and to assist in interpreting some of the conclusions set forth. Similar situations exist in other species, and several types of this same sort of problem have arisen during the course of this study.

There may be some who will consider that I have been too lax in drawing specific lines, but it should be remembered that we are en- deavoring to build up a natural system of classification, and that species are artificial concepts which probably do not exist in nature in as precise a form as they do in the minds of some taxonomists. A species, especially one with a wide distribution, is confronted in nature with a great variety of environmental conditions, many of which exert a powerful influence on the growth and development of the individual. An attempt has been made to take this fact into consideration when making decisions and arriving at conclusions. The species have been treated in the manner which seemed most logical in the light of present information. Some of the problems will be solved definitely only by means of supplementary biological studies. With additional information from that source, and with more material available, some of the conclusions submitted in this paper may have to be altered. There is much to be learned about biological races and the effect of food plants and environment upon the species. When information is available concerning some of these factors it may be possible to explain some of the variation found

HENDERSON: THE GENUS LISTRONOTUS 219

within certain species of Listronotus. It may even be possible to associate certain types of variation with certain ecological or en- vironmental factors, or with certain biological races.

Since Listronotus has never been treated before in monographic form, the purpose of this paper is to bring together the literature and redescribe species which have very brief original descriptions. In- adequate descriptions have been supplemented, and inaccurate state- ments have been corrected. An attempt has been made to present as much biological information as is available. Illustrations and keys are given which should assist in the identification of the species. All material which could be secured has been examined in order to acquire as many data on distribution as possible. The lists of cita- tions to the literature of the species do not purport to be entirely complete, but they do include all the more important references and a great many more which were found by a rather detailed search of the literature. There may be references in a few obscure places which have been overlooked. All the citations known to me con- cerning the economic literature of this group have been included. In a few cases where names have been published in error I have had access to the material in question and have been able to rectify the mistake. In other cases where names have been obviously cited in error, but the material has not been available for study, a note has been added calling attention to the error.

ACKNOWLEDGMENTS

MORPHOLOGY AND TERMINOLOGY

A study was made of the location of the spiracles in order to de- termine what segments of the abdomen were actually represented by the visible sternal sclerites.

Two pairs of large spiracles are found in the thorax. The first of these pairs is in the membrane between the prothorax and the mesothorax. The second pair is in the membrane between the mesothorax and the metathorax and is situated directly behind the mesothoracic epimeron,

There are eight pairs of abdominal spiracles. The third pair of abdominal spiracles is associated with the first visible abdominal sternum, showing that it is in reality the third sternum. The two pairs of abdominal spiracles anterior to this region indicate that the first two sterna have either fused with the third or have dropped out. An examination of the anterior part of the abdomen reveals what is undoubtedly a remnant of the second sternum lying behind

229 THE UNIversiry SciENCE BULLETIN

and above the posterior coxae, and separated from the third sternum by a small inter-segmental fold. The first sternum has probably dropped out. The third and fourth sterna are rather firmly united, there being but little evidence of the antecosta, or inter-segmental infolding, found between the other sterna. There are five visible abdominal sterna, the last being the true seventh. There are often peculiar modifications of the seventh sternum, especially in the fe- male. These may be in the form of elevated ridges, depressions, or pits.

The eighth sternum is internal. In the male there are two sclerotized sternites. In the female the greater portion of the sternum is sclerotized. The degree of sclerotization and the shape of the sclerotized areas is constant within a species, but differs in different species so that we have here a character of great taxo- nomic value.

Because of the characters of taxonomic value located on the ab- dominal sterna it is often necessary to refer to them individually. In the past there have been several terms applied to them which are undesirable for certain reasons. A common practice is to refer to them as “segments” of the abdomen. This term should not be used, because in its proper application it does not include the lower surface alone but the upper part, or tergum, as well. Perhaps the term in most common usage is “sternite.” This term is a diminutive form of the word sternum and as such would be used by mor- phologists to designate one of two or more sclerotized divisions of the sternum, if it consisted of more than one sclerite. Since the sclero- tized plates of the sterna represent essentially all of the sternal portion of the segment, they will be referred to as sterna.

.The five visible abdominal sterna are generally referred to as the first to the fifth, inclusive. The next sternum, the one which is in- ternal, is most often referred to as the eighth, its proper morpho- logical number. This incongruity is confusing, and it would seem more desirable to follow some uniform system of referring to the number of the individual sterna, therefore they will be referred to their proper morphological positions, the five visible sterna being the third to the seventh, inclusive.

In the female the seventh tergum is the last one which is external. The eighth is internal, and its spiracles are very small and ap- parently closed and nonfunctional, although the tracheae still at- tach to them. In the male the eighth tergum is external and is sometimes referred to as the pygidium.

HENDERSON: THE GENUS LISTRONOTUS 223

In discussing the antennae the terms in common usage have been utilized. The long basal segment is called the scape; the series of shorter segments, seven in this genus, is called the funicle; and the enlarged terminal part is called the club. The individual divisions of the antennae are sometimes referred to as “joints,” but this term is not used because it generally implies the concept of an articula- tion rather than a segment. It would perhaps be more accurate to refer to some of the individual divisions of the antennae as sub- segments, since we are told by the morphologists that the antenna is composed of three fundamental segments, and that any addi- tional divisions are due to secondary segmentation, and are there- fore subsegments. Since we do not know which of the divisions of the antennae of the Curculionidae are primary divisions and which are secondary divisions, the term segment will be used instead of subsegment.

The dorsal part of the prothorax is referred to in this paper as the disk of the prothorax rather than as the pronotum. The term pro- notum usually refers to the dorsal sclerite of the prothorax. Since the entire prothorax of the Curculionidae is more or less fused into one somewhat tubular unit, there is no actual line of division be- tween the pronotal region and the rest of the prothorax, and the pronotum does not exist as an actual unit. Therefore the term pro- notum cannot be appled in its proper sense to the dorsal part of the prothorax of the Curculionidae. There is no other morphological term available to apply to this region of the body, and since it was not deemed advisable to coin a new term, the somewhat flattened dorsal portion of the segment is referred to simply as the disk of the prothorax.

In making measurements of the prothorax and other parts of the body an eyepiece micrometer has been used in a binocular. Rela- tive proportions of the length and width of the prothorax are by actual measurement. These measurements do not always agree with what appears to be the condition from a casual observation of the specimen. The prothorax of a species may appear to be longer than wide, and indeed the original description may even describe it as such, but actual measurement may show the width to be equal to the length, or it may even be slightly wider than long. The pro- thoraces of the types of several species which were described as hav- ing the prothorax longer than wide have been measured and have been found to be wider than long. The measurement of the pro- thorax is made from a dorsal view. The longitudinal measurement

224 THe UNIverRsITY SCIENCE BULLETIN

is made through a median line from the base to the apex and does not include the ocular lobes. The transverse measurement is made at the point of the greatest width.

The measurement of the length of the beak is made from a side view. It is the length of a line drawn from the lower corner of the apex to the top of the head at the point marked by the center of the frontal fovea. The mandibles are not included in this measurement since they are sometimes opened and, in these cases, extend for a considerable distance beyond the apex of the beak and would not give accurate or uniform measurements.

Another point which demands an explanation is that of the num- bering of the intervals of the elytra. There are ten striae, dividing the elytra into eleven so-called intervals. In a very few cases some workers have referred to only a part of the elytron located between two striae as an interval. The strip between the first stria and the inner margin of the elytron is sometimes called the suture, and the strip between the first and second striae is sometimes called the first interval. In this paper the term suture indicates the actual line of division between the elytra along the median line of the body. The strip between the suture and the first stria is called the first interval, the strip between the first and second striae is called the second in- terval, and so on, accounting for eleven intervals.

In measuring the total length of the body the length of the beak is not included. The measurement is started at the front margin of the head if the beak is turned down, or if it protrudes anteriorly the measurement is begun from the anterior margin of the eyes. If there are caudal processes on the tips of the elytra they are included in | the total length of the body.

Blatchley and Leng (1916, p. 155) state that the scattered black dots mentioned by LeConte on Listronotus tuberosus LeConte and on other species are only open punctures from which the scales have been lost. This is not the case. If the “black dots” are examined closely it will be seen that they are open punctures, but that they are larger than the other punctures, which can be uncovered by picking off the scales. It will also be seen that instead of the usual scales each of these larger punctures bears a stout semierect seta which is often black and for this reason is not plainly visible against the black exoskeleton of the insect and the shadow within the puncture.

GENITALIA

The male genitalia of Listronotus have been found to possess ex- cellent taxonomic characters of specific value. The main differences lie in the shape of the median lobe and in the various hooks and

HENDERSON: THE GENUS LISTRONOTUS 225

spines within the internal sac. The structures of the internal sac can be studied through the transparent membranes, without the sac being everted, if the preparation is examined in a liquid medium such as glycerine or alcohol. When the membranes become dry they are white and opaque, and the inner structure cannot be seen. There is a small amount of variation in the genitalia, but never enough to cause any confusion, even with closely related species.

The female genitalia are very similar throughout the genus. There are noticeable differences between some species, but in most cases they are of no value in separating species. The internal characters of the greatest value in the female are found in the eighth sternum, which has a characteristic shape in each species.

A number of different methods of preserving the genitalia have been tried, and the one found to be most satisfactory is to store the parts in a small amount of glycerine in the bottom of a tiny vial which is corked up and pinned through the cork to the same pin upon which the specimen is mounted.

Prior to the dissection of the genitalia the labels are removed from the pin, and the specimen is relaxed for a few minutes in a warm solution of five percent alcohol until sufficiently softened to be ma- nipulated easily. In the case of the larger species a hooked minute nadel may be inserted through the posterior opening of the body, and by carefully severing the membranous connections between the sclerites of the eighth segment and those of the seventh, the genitalia and accessory parts may be removed. With smaller species it is sometimes more convenient to remove the entire abdomen, pull away the tergal portion, and then dissect out the desired parts. After the genitalia are removed from the body they should be put into a ten percent solution of caustic potash to soften and partially dissolve the muscle tissue which is attached. This process is hastened if the caustic is hot, and it may even be boiled. After the genitalia have been removed from the caustic the muscle and excess membranous tissue may be easily dissected away.

GEOGRAPHICAL DISTRIBUTION

The genus Listronotus as it is now defined occurs only in North America. Only one species is known from Mexico. Only a few of the species have a range which extends over the entire United States and southern portion of Canada. A number of the species have a more limited range which may include the southern states, or the central and eastern states. Some of the species are very local in

their occurrence, having been recorded from only one or two states. 15—2181

BIOLOGY

Very little is known of the biology of most of the species of Listronotus. The habits of many of the species are entirely un- known. Some have been taken on sandy or muddy ground along the margins of lakes and ponds. Others have been taken by sifting moss and debris in swamps, or they may be found under logs, pieces of wood, or under other cover, either in swamps or on dry ground. A specimen of L. palustris Blatchley in the T. W. Harris collection was found by Doubleday under the bark of rotten oak in eastern Florida. A number of the species are commonly taken at light.

Listronotus tuberosus LeConte has been reared from Sagittaria by Satterthwait. It was determined by him as L. sordidus (Gyllenhal), and the data are recorded under his Webster Groves No. 26558. Criddle has bred the species from Sagittaria at Treesbank, Mani- toba.

Criddle has also bred L. appendiculatus (Boheman) from Sagit- taria at Treesbank. It is quite often taken on Sagittaria and has also been taken on Chelone glabra and on Nelumbo.

Listronotus squamiger (Say) has been reared from Scirpus validus at Milford, Iowa, by Satterthwait.

Listronotus oregonensis (LeConte) does not seem to feed on semi- aquatic plants as do the other members of the genus whose host plant is known. There have been several published records of this species occurring on Sagittaria, but these records are probably based on Hyperodes solutus (Boheman). Chittenden (1924) first expressed doubt as to whether L. oregonensis (LeConte) was the species which had been reared from Sagittaria, and Buchanan (1932) indicates that the species reared from Sagittaria was Hy- perodes solutus (Boheman). For a detailed discussion of the biologi- eal data known for L. oregonensis (LeConte), see the section on the biology of that species.

LISTRONOTUS AS FOOD OF CERTAIN ANIMALS

Through the codperation of A. L. Nelson, Division of Wildlife Research, Bureau of Biological Survey, United States Department of Agriculture, I have been supplied with the data pertaining to numbers assigned to specimens found in the United States National Museum and Biological Survey material which had been recovered in stomach content studies. By the use of these data, some infor- mation can be given concerning the utilization of Listronotus as food by other animals.

One specimen has been found in the stomach of the water snake

HENDERSON: THE GENUS LISTRONOTUS Papel

Natrix sipedon. A number of individuals belonging to eleven dif- ferent species of Listronotus have been taken from the stomachs of various species of Bufo. Judging from these data it would seem that Listronotus is an important item in the diet of toads. The follow- ing information is arranged according to the species of predator

HISTORICAL SKETCH

The first species of Listronotus was described by Thomas Say in 1824 as Rhynchaenus caudatus. In 1826 Schénherr described the genus Listroderes with the South American Listroderes costirostris Gyllenhal as the type species. In 1831 Say referred his species caudatus to the genus Listroderes and described Listroderes squam- iger Say. In 1834 Gyllenhal described Listroderes distinguendus and Listroderes sordidus. In 1842 Boheman described Listroderes inaequalipennis and Listroderes appendiculatus. In 1860 LeConte described Listroderes teretirostris and Listroderes oregonensis.

HENDERSON: THE GENUS LISTRONOTUS 229

In 1864 Jekel wrote his “Recherches sur la Classification Naturelle des Curculionides,”’ in which he described the genus Listronotus. He does not definitely designate a type species, but mentions the names caudatus, squamiger, and inaequalipennis at the beginning of the paragraph of discussion in which Listronotus is named.

In 1876 LeConte brought together the North American species which had been placed in the genus Listroderes and treated them as Listronotus, describing fourteen new species, obliquus, tuwberosus, callosus, americanus, rotundicollis, sulcirostris, nebulosus, frontalis, cribricollis, impressifrons, setosus, punctiger, gracilis, and nevadicus. He included the genus Listronotus, along with Macrops, in a division which he called Listroderi, under the tribe Phytonomini in the sub- family Curculioninae.

LeConte and Horn in their “Classification of the Coleoptera of North America,” published in 1888, again include Listronotus and Macrops in the Listroderi group of the tribe Phytonomini within the subfamily Curculioninae.

Casey described two species of Listronotus in 1895, L. scapularis and L. tessellatus.

In 1902 Champion placed Listronotus and Hyperodes in his Listroderina Group. In regard to the relationship of Listronotus to the rest of the Curculionidae he states: “The affinites of this group, as shown by the Australian genus Desiantha, Pase., seem to me to be with the Erirrhina (Hydronomides), and not with the Hyperina, amongst which it is placed by all North American writers.” In re- gard to the species included within Listronotus, he says: “The North American species referred to Listroderes by Gyllenhal were separated by Jekel from that genus under the name Listronotus, and this course has been followed by LeConte, the chief difference being the posteriorly evanescent scrobes in the South American forms.” At this time Champion described Listronotus bagoiformis.

Blatchley and Leng include Listronotus in the tribe Hyperini of the subfamily Curculioninae, in their arrangement of the genera in “The Rhynchophora of Northeastern America,” which appeared in 1916. Blatchley described four species of Listronotus in this work, palustris, rudipennis, floridensis, and debilis.

In the “Catalogue of the Coleoptera of America, North of Mexico” Leng, in 1920, places Listronotus in a group Listroderi of the tribe Hyperini, following LeConte in this regard.

Chittenden in 1926 described a species of Listronotus which he called lewcozonatus. Van Dyke described L. impressus and L. elegans in 1929.

230 Tue University ScieENcE BULLETIN

In 1931 Pars 114 of the Junk “Coleopterorum Catalogus” ap- peared, covering part of the Curculionidae. Schenkling and Mar- shall, the authors of this section, include Listronotus along with Hyperodes, Listroderes, and related genera, in the subfamily Cylindrorrhininae.

ORIGINAL DESCRIPTION OF LISTRONOTUS JEKEL

“Les unes, la plupart de grande taille (Caudatus, Squamigeér, TInaequalipennis) ont, ainsi que |’ observe M. Lacordaire (loc. cit., p. 344 note 2), quelques rapports avec les Plinthus pr. d. (Lacord.), et me paraissent pouvoir en étre rapprochées, ainsi que le genre Eudocimus, auquel elles ressemblent davantage qu’a tout autre groupe, et qui ne devra pas rester prés des Heilipus. Elles se dis- tinguent de quelques autres espéces de |’ Amérique du nord, relative- ment trés petites (ex.: Hwmilis Sch.), par leurs élytres plus planes en dessus, conjointement émarginées a leur base, a cdté de cette base, remontant assez anguleusement en dehors et au dela des cdtés de la base du thorax, avec les épaules assez obliquement et brusque- ment abaissées, puis les cétés paralléles jusque prés des trois quarts de la longueur; elles sont ensuite étranglées dans leur partie postérieure rétrécie, et leur sommet est prolongé aiguément, formant parfois une sorte de queue quelque peu recourbée inférieurement chez certains g¢. WL’ antenne a son scape atteignant seulement Voeil, sans empiéter sur lui, et le deuxiéme article du funicule est beaucoup plus long que le premeir. Le rostre, long, contigu & la téte qui est trés courte et enfonecée presque jusqu’aux yeux, affecte conjointement avec elle une forme subconique, est pour ainsi dire aussi large qu’elle 4 sa base, et se rétrécit insensiblement jusque vers l’extrémité qui est un peu elargie; de plus, les yeaux étant latéraux, le front se trouve avoir une bien plus grande largeur que chez les vrais Listroderes, et sert de base au cOne supposé que for- ment la téte et le rostre pris ensemble. Le thorax est & peine élargi antérieurement, convexiuscule, et ne justifie déja plus le nom imposé au genre. Je nomme cette coupe Listronotus, car il n’y a en effet que le dos de l’élytre qui soit aplani.”’

GENOTYPE

No type species was designated by Jekel in his original descrip- tion of the genus Listronotus, although at the beginning of the para- graph he mentions the names caudatus, squamiger, and inaequali- pennis. Since caudatus was the first of the three names mentioned by Jekel in the original description of Listronotus and was also the

HENDERSON: THE GENUS LISTRONOTUS Dok

first species described which is now assigned to this genus, I hereby designate Listronotus caudatus (Say) as the type species of the genus Listronotus.

STATUS OF THE GENUS

The genus Listronotus is very superficially separated from Hy- perodes by characters which are not of generic value. If the generic distinctions were strictly adhered to, certain species of one genus would have to be transferred to the other genus, and then there would be found some intermediate species which could not be defi- nitely placed because of the possession of some of the characteristics of both genera.

This paper has been limited to the species now considered to be- long to the genus Listronotus. The species described by LeConte as Listronotus nevadicus has not been included, because it has been found to belong to Dietz’s Ulkei Group, or Blatchley and Leng’s Group II, of the genus Hyperodes. The species represented by the names L. teretirostris (LeConte), L. punctiger LeConte, L. gracilis LeConte, and L. bagoiformis Champion are among the intermediate species mentioned above, and their treatment is being deferred until the appearance of a subsequent paper. Work is in progress on a treatment of the species now listed as Hyperodes. After these species have been studied in detail and the intermediate forms have been carefully considered, the entire series of species will be rearranged, generic concepts will be clarified, and generic limits will be defined. Due to the early stages of the work on this next group of species it would be premature at the present time to attempt to define the genus Listronotus.

According to present concepts the following characters may be utilized to recognize a member of the genus Listronotus: abdominal sterna very unequal, the fifth and sixth together not, or scarcely longer than the fourth or seventh; mandibles two-toothed at tip; antennae with second segment of funicle about twice as long as first; tibiae bent at tip and strongly mucronate at apex.

POSITION OF THE GENUS

Listronotus has been included by American authors in the tribe Hyperini of the subfamily Curculioninae. Champion (1902, p. 120) was of the opinion that it should be associated with the Erirrhinae. The latest work in regard to the placing of the genus was done in 1931 by Schenkling and Marshall in the Junk “Coleopterorum Cat- alogus.” They consider it to be allied to Listroderes and other

232 THE UNIVERSITY SCIENCE BULLETIN

closely related genera, mostly South American and Australian, all of which are included in the subfamily Cylindrorrhininae.

golden, with minute, elevated, black dots: scutel golden: elytra with regular series of punctures; golden color more obscure than that of the thorax; tip of each, elongated into an obtuse caudiform projection: beneath obscurely golden, varied with black: feet fuscous, with short hair; thighs dilated before the tip; a cinereous fascia on the two posterior pairs.

“Length, from the anterior part of the head to the tip of the elytral processes, rather more than two-fifths of an inch.

“Found near Engineer Cantonment on the Missouri river. The caudal processes are peculiar to one sex.”’

AppITIONAL Descriprion. Length, 8 to 12.6 mm. Elongate-ob- long, rather robust. Body black, thickly covered with dark-brown scales. In some individuals the scales may be hght brown or even yellowish-brown, while in other cases they may have a distinctly cupreous tinge. Head, anterior margin of prothorax, a small median basal spot on the prothorax, base of elytra, and scutellum covered with slender, elongate scales which are usually bright, shining cupreous, but are sometimes shining golden, or may be dull brown. There is a rather narrow vitta of paler scales at each side of the disk of the prothorax and sometimes a very narrow pale median vitta in which the scales may be slightly narrower. Beak scarcely as long as prothorax; median carina narrow, smooth, polished, slightly elevated; lateral carinae and lateral sulci usually obsolete; punctures of beak moderately coarse, dense, sometimes slightly rugose, mostly covered by cupreous scales which are somewhat broader than those of head; a few scattered broader scales, espe- cially on the basal portion of the beak. Antennae dark reddish- brown; second segment of funicle about twice as long as first; third segment noticeably longer than the fourth. Head very convex, densely punctate; frontal fovea rather deep, elongate. Disk of prothorax one-fifth wider than long; ocular lobes moderately de- veloped; sides of prothorax of male nearly straight from base to apical third and then curving in, female with sides more evenly rounded along entire length, with greatest width about at middle; disk slightly convex, densely punctate, the punctures being covered by scales; a few scattered larger punctures on disk open and bearing setae. Scutellum slightly elongate. Elytra deeply emarginate at base, humeri right-angulate; striae fine, with very small, remote punctures, each bearing a tiny seta; intervals very slightly convex, with a tendency for the third and fifth to be more convex; each in- terval with a row of short, suberect, sparsely placed setae, the third,

fifth, and sometimes the seventh intervals with two or three con- fused rows of setae; the elytra with scattered transverse wrinkles which may traverse one or two, or occasionally parts of three intervals. Ventral surface with sides of the third and fourth ab- dominal sterna thickly clothed with broad, cupreous or dark-brown scales, with a few intermixed black ones; elsewhere with less densely placed elongate scales. Male with elytra conjointly rounded at tip. Female with elytra separately prolonged at tip into rather long, cylindrical processes which are usually parallel but may be con- vergent and are sometimes tapering instead of cylindrical. The seventh (fifth visible) abdominal sternum of the female is slightly wider than long, with a shallow, elongate concavity toward each lateral margin and an indistinct triangular concavity on the median caudal portion, with the apex of the triangle cephalad. The tri- angular concavity is sparsely and finely punctate, with the punc- tures bearing slender semierect setae. The lateral concavities are densely punctate, with the setae prostrate and somewhat thicker. There are a few scattered punctures which are larger and bear rather long, erect, stiff hairs. The median anterior por- tion of the seventh (fifth visible) sternum is impunctate, shining and alutaceous; the tip is slightly rounded, with a faint emargina- tion toward each side. The conditions described above are typical, but there are slight variations found in some specimens. The modification, however, is never very great.

Nores on Types. The types of this species have been lost or destroyed and neotypes are being erected. A map of the itinerary and camp sites of the expedition of which Say was a member at the time he took this species has been checked, and “Engineer Canton- ment” on the Missouri river, the type locality given in the original description, was found to be very near the present location of Council Bluffs, lowa. Neotypes have been chosen, therefore, from Kansas, Missouri, and Iowa, all in the general region from which the species was described. Neoholotype and neoallotype deposited in the Francis Huntington Snow Entomological Collections at the University of Kansas. Neoparatypes in the Snow Collections and in the United States National Museum.

Neoholotype male, “Douglas Co., Ks., 6-22-34, L. 8. Henderson.” Neoallotype female, “Douglas Co., Ks., 6-22-33, L. 8. Henderson.” Seventeen neoparatypes as follows: 1 male, “Douglas Co., Ks., 6-22-33, L. S. Henderson’; 1 female, “Lawrence, Kansas, 6-26-33, L. S.

REMARKS AND COMPARATIVE Notes. Sometimes the females of this species have been determined as L. inaequalipennis (Boh.). They may be distinguished from L. inaequalipennis (Boh.), a syno- nym of L. squamiger (Say), by the lack of the peculiar development of the elevated flaps of the seventh abdominal sternum of that species. Other specimens have been determined as L. callosus Le- Conte, from which they may be separated by the less deeply emargi- nate base of the elytra and the less prominent posterior calli. The elytral intervals are also less convex, and there are usually promi- nent transverse wrinkles of the elytra which are not present in L. callosus LeConte. These species may be easily separated by an ex- amination of the internal genitalia.

The tips of the elytra of the male are usually conjointly rounded. Two male specimens have been found, one from Albert Lea, Minn., and the other from Iowa City, Iowa, in which there is a short tuber- cle at the apex of each elytron, suggesting a slight development of the long cylindrical process which is characteristic of the female of this species.

The range of this species is now known to include California, Oregon, and British Columbia. There are variations in some of the specimens from the new localities, and these will be discussed in some detail to avoid possible confusion. In a series of specimens from Oregon, most of them from Dalles, the most noticeable differ- ences have been found. The most apparent variation is that of the shorter processes found on the tips of the elytra of some of the fe- males. In one of the specimens the elytra are but slightly more than acuminate at the apex. In othes specimens the processes are longer, but not quite as long as is typical of the species. Still others are en- tirely normal. In some of the specimens the beak is a little thicker and is more strongly curved on the upper surface. In these indi- viduals the beak is usually distinctly tricarinate, the median carina being narrow, sharp, and smooth, the lateral carinae broader and rather densely punctate. The anterior half of the disk of the pro-

238 THE UNIversiItTy ScreENCcE BULLETIN

thorax often has a fine median carina. There is sometimes a slight granulation of the surface of the prothorax, giving it a rough ap- pearance, the rougher sculpture being more apparent on the sides than on the disk. An examination of the sclerotized portion of the eighth sternum of the female shows that the basal piece is sometimes shorter than usual, but that the shape of the terminal arms is typi- cal. The extent of the modification of some of these individuals might suggest the possible existence of a variety or even a geographic race. After careful consideration, the conclusion has been reached that it would not be wise to give such rank to these specimens, at least in the light of present information, and with the small number of specimens available. During the course of the examination of a large number of individuals of this species from the eastern states, tendencies toward all of these modifications have been noticed. There are often faint traces of a median prothoracic carina, and in some cases the carina is rather strongly developed. The sides of the prothorax are often rough or granulate, and the punctation of the disk is variable. In some cases the beak has only a median carina, but many times the lateral carinae are well developed. An indica- tion of the variation of the elytral processes has already been given in the description of the species. Specimens from other localities which are in the outer limits of the range of the species may show various degrees of development of one or more of the variable char- acters mentioned, so that we have some intermediate forms between the typical condition found in the northeastern states and the condi- tions found in some of the specimens from Oregon. There is a fe- male from Creston, British Columbia, less than five miles above the Idaho line, in which the caudal processes of the elytra are very short; the beak is not thickened, and the lateral carinae are present but not strongly developed; the basal piece of the eighth sternum is moderately long. A male from Nevada has been seen which is typical in all respects. Two females from Dry Lake, Utah, have the lateral carinae of the beak very prominent and the prothorax somewhat granulate on the disk and rough on the sides; the caudal processes of the elytra of these specimens are typical, and the basal piece of the eighth sternum is long. A male seen from Salt Lake, Utah, is normal in all respects. Females from Colorado and Texas have been examined which were typical in all respects. A male from Texas has the transverse wrinkles of the elytra very promi- nent; the disk of the prothorax has more large open punctures than usual, and there is a slight constriction of the sides at about the middle. There are sometimes lesser indications of this constriction

HENDERSON: THE GENUS LISTRONOTUS 239

in other specimens. It seems plausible to assume that the atypical Oregon specimens are merely individuals at the extreme limits of the range of the species, in which there is an unusual amount of variation, when we consider that there are tendencies toward these same variations in some individuals in the eastern states, that there are some intermediate forms in the intervening territory, and that not all the specimens from Oregon exhibit variation to the same ex- tent, some of them being entirely normal.

BrotoaicaL Notes. This species has been recorded as having been taken on several different plants, and a number of new records are given here. A great variety of plants are included on the list, and it is doubtful that all of them are actual food plants. The beetles may have been only resting on some of the listed plants at the time they were taken.

Beutenmiller (1890 and 1893) states that F. M. Chittenden found the species with L. tuberosus LeConte and L. appendiculatus (Bohe- man) while sweeping a small patch of aquatic plants composed en- tirely of Sagittaria and Carex. It was recorded by Popenoe (1878) from Topeka, Kan., as occurring with L. nebulosus LeConte on Sagittaria. The record of L. nebulosus LeConte in this case is prob- ably based upon a male specimen of L. caudatus (Say). Popenoe states this his specimens were determined by LeConte, and I have seen a male of L. caudatus (Say) from Topeka, Kan., which not only bears the label of nebulosus in LeConte’s own handwriting, but it is one of the rare labels which states that the determination was made by LeConte. Blatchley and Leng (1916) state that the species has been recorded from the mild smartweed, Polygonum hydropiperoides Michx., and on arrowhead. Bleasdell (1937) states that two specimens of L. caudatus (Say) were taken by Mr. Sooter on a species of Scirpus at Lost Island, Ruthven, Iowa.

The following are the new records: on oak sprouts, May 13, at Oregon, Illinois; taken on jointgrass by G. Stace Smith at Creston, British Columbia, on July 12; taken on corn at Meredosia, IIl., by H. E. Roberts; taken on dock at night by F. A. Fenton, at La- fayette, Ind., May 22; taken on hickory at the same locality by Satterthwait, on June 21.

The species is often taken at light. It was found under a log on July 8, at Amora, Ill. McElfresh found a number of specimens at Urbana, Lll., around stumps in overflowed land in April.

Data on DistriputTion. Blatchley and Leng (1916), give the following information as to the distribution of this species: “Fre- quent throughout Indiana, May 25-October 12; mating June 20.

Listronotus ingens new species

(Plate XXXII, figs. 2, 2a; Plate XX XVII, fig. 4)

Length, 11to13.5mm. Large, oblong, stout. Body black. Head, beak, median half of disk of prothorax, middle of thoracic sterna and all of abdominal sterna rather thinly clothed with very narrow scales or setae which are brownish-cinereous, sometimes with a slight cupreous tinge; sides of prothorax and elytra clothed with small, rounded, dull-brown scales. Sixth and seventh intervals of elytra sometimes with mottlings of cinereous scales, or rarely al- most entirely light-colored from humeri to apical third of elytra; occasional small scattered patches of lighter scales on basal half of sides of elytra. Beak slightly longer than prothorax, moderately stout, very shghtly curved in male, more strongly curved in fe- male; usually rather strongly tricarinate; median carina always prominent and sharp; lateral carinae more rounded, always pres- ent but occasionally less pronounced; lateral sulci present but rather broad and shallow; finely and densely punctate. Head strongly convex, densely punctate; frontal fovea deep, elongate, sometimes continuing upward for a short distance onto the head as a sharp, narrow sulcus. When viewed from the side there is usually a rather pronounced impression at the point of the frontal fovea, between the convex head and the base of the curved upper surface of the beak. Antennae with second segment of funicle not quite twice as long as first; third segment elongate, longer than fourth, and about the same length as the first; seventh segment more closely united with the club than in the other species of this group. Prothorax one-fifth wider than long; ocular lobes not very strongly developed; sides broadly rounded, widest slightly beyond the middle; apex truncate, base slightly curved, basal angles rounded; disk convex, densely but very shallowly punctate; median half of disk clothed only with very slender scales. »Scutellum elongate, very densely covered with minute buff-colored scales. Base of elytra rather deeply emarginate; humeri right-angulate or very slightly oblique, with a rather prominent angulation just behind the humeri; sides nearly parallel to apical third, then narrowed to the conjointly

244 THE UNIvEerRsITy SciENCE BULLETIN

rounded apices; striae fine, not strongly impressed, punctures moder- ate, distant; intervals slightly convex, sometimes slightly roughened by transverse wrinkles; setae very short and slender, confused on third, fifth, and seventh intervals, in a single row on the others; posterior calli scarcely evident. Ventral surface clothed mostly with slender scales; finely and densely punctate. Male with a broad, feeble, median impression across all of the third (first visible) abdominal sternum and the basal half of the fourth; seventh (fifth visible) sternum unmodified. Female with a somewhat tri- angular area at base of seventh (fifth visible) abdominal sternum devoid of punctures and scales, shining, but minutely reticulate.

B.” Holotype and allotype in the American Museum of Natural History. Paratypes in the American Museum of Natural History, United States Na- tional Museum, Museum of Comparative Zoélogy at Harvard Col- lege, Francis Huntington Snow Entomological Collections at the University of Kansas, and in the entomological collections of Purdue University and at College Station, Texas.

REMARKS AND Comparative Notes. This species is very closely related to L. caudatus (Say). The shape of the eighth sterna of the females is very much the same, but there are slight differences which are constant and specific in nature. The females of the two species may be easily separated by the absence of the caudal proc- esses of the elytra in L. ingens n. sp. The male genitalia of the two species are very distinct. L. ingens n. sp. may be recognized by the setae on the median half of the prothorax, by the strongly tricarinate beak, and the deep frontal fovea. LL. caudatus (Say) has a few slender seales along the median line of the disk of the prothorax, but they are not hairlike and do not extend laterally beyond the median line. The following external characters will be found of value in separating L. ingens n. sp. from L. caudatus (Say): beak more strongly curved and the lateral carinae more distinct; frontal fovea deeper; scales on median half of disk of prothorax more hairlike; larger punctures bearing dark, stout, semierect setae very sparse or absent; sides of prothorax more rounded; humeri a little more oblique, elytra smoother, sometimes with mottlings of cinereous scales; ventral surface with fewer rounded scales, almost none on the fourth (second visible) abdominal sternum.

OriGINAL Description. “Blackish, covered with round, dirty- brown scales, becoming larger on the prothorax, less dense and hair- like upon the head and beak. Beak as long as the prothorax, strongly carinate and suleate. Prothorax scarcely as long as wide, rounded on the sides, narrowed before the middle, constricted to- wards the tip; marked with two sinuous lateral vittae, and a scarcely distinct dorsal line of pale scales. The punctures are less concealed by scales than in the species above described [L. caudatus (Say) |, and are very coarse and dense. Scutellum pale. Elytra strongly emarginate at base, humeri oblique, sides then parallel, rounded be- hind; the posterior callus is distinct, not very prominent; the elytra are compressed at the suture towards the tip, and vertically de- clivous; the striae are strongly punctured, the interspaces somewhat uneven; there is an indistinct broad stripe commencing at the hu- meri and running backwards on the sixth, seventh, and eighth inter- spaces, and there are besides some irregular mottlings of pale scales. Beneath punctured, irregularly spotted with large pale scales; thighs with a pale band. Length, 14 mm.; .55 inch.

“Female. Last ventral deeply concave, the excavation smooth at the bottom, and transversely impressed with a short line, becom- ing narrow at the tip, which is deeply emarginate; the upper mar- ginal line is continued around the tip, separate from the lower one, and the space between them is curiously and deeply marked with two excavations on each side near the extreme emargination; py- gidium strongly emarginate; tips of the elytra separately rounded. Male wanting.

under other species. It is the Eudocimus americanus De}. Cat. 299, but bears no resemblance to Hu. mannerheimu.”

AppITIONAL Description. Length, 10.5 to 14mm. Beak slightly longer than the prothorax, tricarinate; median carina sharp and smooth, lateral carinae broader, more rounded, and punctate; there is a very distinct deep lateral sulcus on the basal half of the beak; upper surface rather coarsely punctate, slightly rugose on sides and on the head between the eyes; frontal fovea rather deep. Antennae slender; second segment of funicle about twice as long as first; third segment distinctly longer than fourth, about the same length as the first; seventh segment enlarged and rather closely joined to the club. Disk of prothorax slightly wider than long; ocular lobes moderately developed. The base of the elytra is more deeply emarginate in this species than in any other, causing the humeral angle to be rather oblique; anterior margin along first five elytral intervals somewhat elevated; the basal region of the tenth and eleventh inter- vals directly beneath the humerus is impressed, giving a sharp and rather prominent appearance to the humeri when viewed from the front; alternate intervals slightly more convex; transverse wrinkles give a rough appearance to the elytra. Legs rather long; tibiae with a rather stout mucro and a fringe of long, yellow hair on the ex- treme apical portion along the inner or lower margin. Male with tips of elytra conjointly rounded and seventh sternum broadly con- vex in the anterior half.

Norres oN Types. LeConte described this large and interesting species from three females which he stated were from Georgia. These specimens have been examined. Two are in the LeConte collection in the Museum of Comparative Zoélogy at Harvard Col- lege and the other is from the Horn collection and is in the collection of the American Entomological Society in the Philadelphia Academy of Natural Sciences. All three of these specimens bear the orange disk of colored paper which LeConte used to indicate the “southern states.”

Bro.tocicaL Notes. Nothing is known of the biology of this spe- cies. Dr. H. P. Léding of Mobile, Ala. (in litt., Jan. 24, 1986), says: “T have taken L. americanus here, but it seems extremely rare, or at least hard to find. I have not so far been able to associate the spe- cies with its food plant.”

Data on DisrriputTion. Only seven specimens of this species have been seen. There is a female in the United States National Museum from the collection of Bovie, bearing the label “Patrie?.”

OriGINAL Description. ‘“Blackish, densely clothed, as in the other species, with small, rounded scales, becoming larger on the prothorax, and hairlike upon the head, they are dirt-colored on the general surface of the body, but pale at the sides of the prothorax and elytra, and on a narrow dorsal vitta of the former. Beak as long as the prothorax, distinctly carinate and sulcate, prothorax scarcely as wide as long, broadly rounded on the sides, gradually narrowed in front of the middle, marked as usual with scattered black dots. Seutellum pale. Elytra strongly emarginate at base, humeri oblique, striae strongly punctured, interspaces wide, somewhat convex; posterior callus rather prominent, oblong, fading in front into the fifth and adjoining interspaces. Beneath dirty-brown, speckled with black punctures. Length, 9-10.5 mm.; .35-.42 inch.

“Male. Last ventral segment not impressed, anal segment very shghtly visible behind the last ventral.

“Female. First and second ventrals with a broad, shallow im-

248 THE UNIVERSITY SCIENCE BULLETIN

pression, last ventral with a deep, round excavation extending from the base to the tip; pygidium semicircularly emarginate at tip; elytra separately subacuminate at tip.

“New York to Georgia. The posterior callus of the elytra is about as prominent as in L. squamiger, but not so narrow.”

ApDITIONAL Description. Length, 8-11 mm. Median carina of beak sharp, distinct; lateral carinae more rounded and less promi- nent than median carina; beak slightly longer than prothorax. There is a rather deep sulcus between the lateral carina and the scrobe of the antenna, beginning at the base of the beak. This sulcus becomes less deep as it extends forward and becomes obsolete slightly beyond the middle. Disk of prothorax one-fifth wider than long; ocular lobes moderately developed. The scattered black dots of the prothorax mentioned in the original description are the scattered larger punctures which are open and bear setae instead of scales. The depression of the seventh abdominal sternum of the female is transverse rather than rounded. Although the depression is usually deep there are occasional specimens with a rather shallow impression.

Nores on Types. The types of this species have been examined. They are located in the LeConte collection in the Museum of Com- parative Zodlogy at Harvard College. There are two specimens at the head of the series which bear type labels. The first is a male and the second is a female. They both bear the pink disk which LeConte used to indicate the “middle states.” These two specimens agree with LeConte’s description of the species. There are three additional specimens in the series, all L. squamiger (Say). The first of these specimens is from “Can.,” and since Canada is not mentioned in the original description, this specimen, and the other two labeled “N. Ill.” were undoubtedly added to the series at some later time. LeConte gives New York to Georgia as the range of L. callosus LeConte. The New York record is undoubtedly based upon a misidentification. I do not know where the types were col- lected, but they probably came from some locality north or west of Georgia, since Georgia was considered by LeConte as a southern state and the types are said to come from the “middle states.” I have seen representatives of this species from only as far north as South Carolina.

REMARKS AND Comparative Nores. One male specimen was found which bears the label “Listroderes squamiger Say, Lec./74.” This label was written two years before the present species had been described. Male specimens of L. caudatus (Say) are frequently

HENDERSON: THE GENUS LISTRONOTUS 249

found which have been determined as L. callosus LeConte. The latter species may be distinguished from L. caudatus (Say) by the more deeply emarginate base of the elytra and the more prominent posterior calli. The elytral intervals are more convex and are with- out the transverse wrinkles which are present in L. caudatus (Say). Some of the large representatives of L. sordidus (Gyllenhal) are very similar to L. callosus LeConte; however, in the latter the base of the elytra is a little more emarginate and the humeri are more acute, the posterior calli of the elytra are less pronounced, the beak is heavier and thicker, and the median carina is stronger. In the females the two species may be easily separated by the caudate elytra of L. sordidus (Gyllenhal).

Brotocicat Nores. Nothing is known of the life history or food plant of this species. It has been recorded by Townsend (1885) as having been taken in some numbers with L. tuberosus LeConte, L. nebulosus LeConte, and L. frontalis LeConte under old railroad ties and pieces of wood in dry places during the first part of April.

Dara on DistripuTion. The distribution of this species as given by LeConte in the original description has already been discussed in the paragraph concerning types. Blatchley and Leng (1916) add Ontario, District of Columbia, New Jersey, Michigan, Illinois and Louisiana. All these records, except the one for Louisiana, are erroneous, since the species does not extend into any of the northern states. The northern records for this species are based on misde- terminations, the confusion probably being with L. caudatus (Say) and L. squamiger (Say), representatives of both having been found determined as L. callosus LeConte. Mitchell and Pierce (1911) record the species as having been collected by Walker in Victoria county, Texas, June 18, 1904.

The center of population of this species seems to be in Louisiana, the great majority of the specimens examined having come from there. A few specimens have been seen from other states. Material has been examined from the following localities:

South Carolina: So. Carolina. Georgia: Geo. Alabama: Ala. Louisiana: Louisiana; La., Horn, 7/10/73; New Orleans, La., 28/2/93 and 26.X.91; New Orleans, La., 11/3, 26/3, 6/6, and 10/6; New Orleans, 11/3. Texas: Tex.; Willis, Tex., ’03.

HENDERSON: THE GENUS LISTRONOTUS 251

OrIGINAL Description. ‘Body covered with minute brownish cinereous scales: rostrum with a carinate line; thorax with scattered punctures; not flattened; scutel yellowish or whitish, elytra with punctured striae towards the tip concealed by the scales; the united tip obtusely rounded; humeri obtuse.

“Length, from two-fifths to half an inch.

“Tnhabits Arkansaw.

“Much like caudatus, but in that species the humeral line is cari- nate and acute.”

ADDITIONAL Description. Length, 7.5 to 10mm. Elongate-ob- long, black. Densely covered with dark brown or fuscous scales, sometimes with a slight cupreous tinge, especially on the head and sides of the elytra; thorax with an oblique stripe of pale scales on each side, continuing posteriorly onto the elytra as a very small humeral spot; median thoracic vitta sometimes entire, usually in- terrupted at middle, and sometimes only very faintly indicated. Beak moderately stout, equal in length to the prothorax, slightly thicker and with upper surface more strongly curved in female than in male; median carina distinct and sharp, but fine; lateral carinae absent and lateral sulci faint; surface finely and densely punctate, rather thickly clothed with small, slender scales. Second segment of funicle of antenna about twice as long as first, third segment longer than fourth. Head finely and very thickly punctate, covered with small, elongate scales; frontal fovea moderately impressed. Disk of prothorax slightly wider than long; ocular lobes well-de- veloped; sides of prothorax nearly straight, slightly constricted at apex, basal angles rounded; base slightly arcuate; disk densely punctate, each puncture covered by a rounded, striate scale; a few scattered punctures larger, open, bearing coarse brown semierect setae. Scutellum elongate, thickly covered with light, slender scales. Elytra emarginate at base; humeri rounded; sides parallel to apical third, then converging to apex; odd intervals elevated and usually connected by transverse wrinkles which vary greatly with different individuals in the number and degree of convexity; elytra thickly clothed with small fuscous scales; third, fifth, and seventh intervals with several confused rows of coarse, brown semierect setae, other intervals with a single row; striae fine, remotely punctate, each punc- ture bearing a very short slender seta; posterior calli of elytra not very prominent. Ventral surface with sides of mesosternum and the mesothoracic pleurites very sparsely clothed with a few rounded scales and some slender setae; sides of metasternum densely covered

252 THE UNIVERSITY ScIENCE BULLETIN

with scales, the median area with rather short, slender setae. Legs densely squamose and setose, femora with a preapical spot of lighter scales on outer side. Male with abdominal sterna densely punctate, third sternum more sparsely punctate than the others; intervals be- tween the punctures shining and very minutely reticulate; large and small punctures intermixed, especially on the last three visible sterna, the small punctures bearing short, slender, decumbent setae, the larger punctures bearing long, coarse, semierect setae; squamose areas only on the sides of the third and fourth abdominal sterna; a rather broad, deep, median impression on the third abdominal ster- num and the basal half of the fourth. Terminal spur on hind tibia broad, flattened, somewhat spoon-shaped. Apex of elytra conjointly rounded. Female with abdominal sterna more finely and densely punctate than in the male, but also having the surface shining and minutely reticulate; third abdominal sternum with short setae at base and in small depressed median area toward the apex, the rest of the sclerite squamose; fourth abdominal sternum squamose over its entire surface; fifth and sixth abdominal sterna with small lateral squamose areas; seventh abdominal sternum with two strongly elevated folds toward the tip, each inclined posteriorly, beginning at the posterior corners of the sclerite and extending cephalo-mesad to about the middle of the sclerite, but not meeting; the median part of the sclerite, anterior to the area enclosed by the lateral folds is shining and impunctate, but minutely reticulate. The seventh ter- gum is somewhat prolonged into a subacuminate tip which projects | ventrally between the tips of the elytra and the last visible sternum, reaching a little beyond the level of that sclerite and a very short distance into the space between the lateral folds. The apical spur of the hind tibia is rather broad and stout, and somewhat flattened. There is a blunt tooth near the base of the spur and nearly at right angles to it. The tooth is quite variable in its extent of develop- ment, sometimes becoming approximately the same size as the main spur and in these cases the effect is to produce a spur with a bifid tip. The tips of the female elytra are usually separately sub- acuminate. In some individuals the tips of the elytra are prolonged into caudate processes such as are found in L. caudatus (Say). All degrees of development are found between these two extremes. Specimens examined which have exhibited the caudate condition of the elytra have usually been from New Jersey and the District of Columbia.

Nores ON Synonymy. Listronotus inaequalipennis (Boheman)

HENDERSON: THE GENUS LISTRONOTUS 253

has been found to be a synonym of L. squwamiger (Say), the latter name having priority by eleven years. The type of L. inaequalipen- nis (Boheman) has been examined and does not differ from L. squamiger (Say). The type specimen is a male. The differences upon which Boheman based the identity of the species are only individual variations. Throughout his entire description he com- pares the species to L. squamiger (Say), stating that L. inaequali- pennis (Boheman) is “distinguished from it only by the distant transverse wrinkles of the elytra, and the more elevated alternate intervals.” During the course of the examination of several hundred specimens of this species these characters have been found to be quite variable. Although Boheman’s type is somewhat roughly sculptured, having rather distinct alternate intervals and trans- verse wrinkles on the elytra, this appearance is emphasized by the fact that the specimen has been rubbed, removing the scales from the convexities and exposing the black, shining elytra in these places.

Harris (1835), in the catalogue of the insects of Massachusetts, lists the name reticulatus under the genus Curculio (Listroderes, Sch.). I have seen the specimens on which this record is based, located in the Harris collection in the New England Museum of Natural History in Boston. They are L. squamiger (Say), and L. reticulatus (Harris) is a nomen nudum, since a description of the species was never published. Although Harris did not attribute the name to Say in the catalogue, Harris’ own books indicate that reticulatus was a Say manuscript name in Listroderes, but this name was never published by Say.

Norrs on Types. The types of this species have been lost, as have most of the other Say types. Neotypes are being designated. The species was described from “Arkansaw,”’ and a few specimens from that state have been seen, but the greater part of the range of the species is more northern, and for this reason the types were selected from Iowa. Another reason is that the Arkansas specimens were very few and were in poor condition, while longer series of per- fect and typical specimens could be secured from Iowa.

REMARKS AND COMPARATIVE Nores. Reference has already been made to the caudate condition of the elytra of some females of this species. There is a limited region along the Atlantic coast be- tween Massachusetts and North Carolina where females have been found with caudate elytra. No other difference can be detected between these females and others of the species without the pro- longations of the tips of the elytra. The peculiar development of the seventh sternum is the same and the eighth sternum is the same. No difference at all can be found between males from this region and those from other localities. Specimens have been taken over a long period of years, so this is not some variation which occurred during one season and then ceased to exist. Dates of collection have ranged from March to August, excluding the possibility of seasonal effect upon development. No explanation can be offered as to the causes of this condition. Some workers might be inclined to assign a name to these caudate individuals, but until more is known of the biology of the species and the nature of the cause of this development such action would be unwise.

Most of the females seen with caudate elytra have been from Massachusetts, New Jersey, and Washington, D. C. The point farthest south is Raleigh, N. C. Females with both caudate and rounded elytra have been seen from Virgina. All females examined from the District of Columbia have had caudate elytra. Several specimens from Delaware and Philadelphia, Pa., were caudate. Some caudate females were found from Long Island, N. Y., and others were labeled only New York, but were probably from the eastern part of the state. A long series of females from New Jersey has been examined, and in this locality are found all stages of gra- dation from a condition in which there are long processes on the elytra to one in which the elytra are conjointly rounded.

A series of fifteen specimens has been arranged to show the grada- tion between the two extremes. These specimens are being desig- nated as plesiotypes and are numbered consecutively. They will be deposited in the United States National Museum, and the series is to be kept intact.

A very few caudate females have been seen which were not from the Atlantic coastal region previously mentioned. A specimen from Marquette, Mich., has the elytra prominently acuminate at the apex. A specimen from Indiana has very short acuminate processes. An-

HENDERSON: THE GENUS LISTRONOTUS ea,

other individual from Aweme, Manitoba, is included as plesiotype number four in the series described in the preceding paragraph, and has elytral processes which, although distinct, are not as strongly developed as in some cases. A specimen from Ohio has prominent caudal processes.

LeConte (1876) recognized only one female of L. squamiger (Say) from Georgia. The males of this species were treated as L. in- aequalipennis (Boheman). LeConte applied the name L. inaequali- pennis (Boheman) to the females with caudate elytra. Blatchley and Leng (1916) followed LeConte in the application of the name L. naequalipennis (Boheman) to the females with caudate elytra. Males were treated both as L. squamiger (Say) and L. inaequali- pennis (Boheman).

L. squamiger (Say) is sometimes confused with L. caudatus (Say), but may be separated from it by the more rounded elytral humeri and the peculiar structure of the spurs of the hind tibiae. The fe- male may also be readily distinguished by the structure of the last visible abdominal sternum. This species is also sometimes confused with L. callosus LeConte and here again it may be separated by the rounded humeri, the spurs, and the structure of the seventh ab- dominal sternum of the female.

A female was found from Millers, Ind., with quite a deep median longitudinal sulcus on the disk of the prothorax. The sulcus is deep- est at the base of the prothorax and within it there is a rather sharp median carina, interrupted at the base and the apex.

Broutocicat Notes. This species is often attracted to light. It occurs along the margins of lakes and ponds and has been found un- der cover in swamps, or by sifting moss and debris in swamps. It has been reared from Scirpus validus Vahl., by Satterthwait. Blatch- ley and Leng (1916) state that the larvae live in the stems of the broad-leaved arrowhead, Sagittaria latifolia Willd. Beutenmiiller (1893) says that according to Hamilton the larvae live in the stems of Sagittaria variabilis.

Specimens have been examined which had been taken from the stomach of Bufo americanus. The records are: Palo Alto county, Iowa, 7-5-07 and 7-16-07, A. G. Ruthven; Stevens Pt., Mellen, Wis., July 19, 1918, A. I. Ortenburger; and Harbert, Berrien county, Michigan, July 13, 1917, A. G. Ruthven. Another specimen has been examined which had been taken from the stomach of a female water snake, Natrix sipedon, taken at Bennings Marsh, D. C., April 22, 1917, by E. G. Holt.

Data oN DistripuTion. Described by Say from “Arkansaw.” Recorded by LeConte (1876) from Georgia. Blatchley and Leng (1916) give the range as “‘from Quebec and New Jersey to Illinois, south to Georgia, Arkansas and Louisiana.” I have seen no speci- mens from as far south as Louisiana. Representatives of this species have been seen from Canada, extending from Ontario to British Columbia, and from the United States from the northern, eastern, and central states, extending as far south as North Carolina, and west to Kansas, Nebraska, North Dakota and Montana. I have also seen one specimen labeled “San Francisco, California,” but until additional specimens are seen, either from there, or from regions between there and the area now known to be inhabited by the species, there will be some doubt as to the authenticity of this label. Specimens have been examined from the following localities:

OrIGINAL Description. “Black, densely clothed with yellowish- brown rounded scales, which become larger on the prothorax, and hairlike upon the head. Beak as long as the prothorax, stout, cylindrical, carina and grooves obsolete, frontal fovea feeble. Prothorax as wide as long, sides nearly parallel, suddenly rounded

and narrowed near the tip, indistinctly trivittate with pale and sprinkled with large, distinct black dots. Scutellum pale. Elytra at base broadly emarginate, humeri oblique, so that they become one-third wider than the prothorax, sides gradually narrowed be- hind the widest part; posterior callus large, conical, prominent; striae punctured, interspaces wide nearly flat; scales uniform in color, very dense, setae very short. Beneath of the same color as above, hind thighs with a pale band. Length, 7 mm.; .28 inch.

“Male. First ventral segment flattened at base, anal segment protuberant beyond the fifth ventral and visible from beneath; elytra rounded at tip.

“Female. Last ventral segment feebly impressed near the tip, each elytron prolonged at tip into a long, straight process.

“Michigan to Georgia. Easily known by the absence of the carina and grooves of the beak, which are so obvious in the two preceding species [L. obliquus LeConte and L. sordidus (Gyl- lenhal) ].”

AppITIONAL Descriprion. Length, 5.5 to 9 mm. The scales are often of a bright coppery tinge. There is a narrow median vitta of brighter scales on the prothorax, and there is a wider sinuate vitta of similar scales on each side of the disk. Beak about equal in length to the prothorax, rather strongly curved; upper surface usually rounded and with no indication of median carina except at extreme tip; occasional specimens with faint median carina and shallow lateral grooves. Frontal fovea usually quite deep instead of feeble as indicated in the original description. Prothorax wider than long. The large, black dots mentioned by LeConte are larger punctures which bear elongate, prominent setae instead of the flattened scales which cover the other punctures of the prothorax. Striae of elytra very slightly impressed, punctures rather deep, very narrow and elongate, each bearing a tiny seta; intervals nearly flat, but elytra usually rather rough and uneven due to the presence of low, irregular, transverse wrinkles; each interval with a row of short, rather distant setae. Male with tips of elytra conjointly rounded; third and fourth abdominal sterna with a median longi- tudinal concavity; seventh abdominal sternum with three very slight concavities, one median and longitudinal, the other two lateral, confined to the posterior half of the sclerite. Female with tips of elytra prolonged into long cylindrical processes which may be either parallel or convergent; third abdominal sternum feebly concave at middle; seventh abdominal sternum with a median convexity.

HENDERSON: THE GENUS LISTRONOTUS 261

Norrs on Types. The type of this species has been examined in the LeConte collection in the Museum of Comparative Zoology at Harvard College. The first specimen in the series, and the only one bearing a type label, bears the orange disk, indicating “‘south- ern states,” and is probably from Georgia. It is a male and is covered with an incrustation of dirt. The second and third speci- mens in the series are a female and a male, both good, clean speci- mens, but bearing no other label than one indicating their sex. The fourth specimen is a female of L. sordidus (Gyllenhal) and bears only the number 1390.

REMARKS AND CoMPARATIVE Nores. Very closely related to L. sordidus (Gyllenhal). For a detailed discussion of the differences see the section of this same heading under that species.

Brotoaicat Nores. The food plant of this species is Sagittaria. It was bred from Sagittaria by Criddle at Treesbank, Manitoba. It was reared from Sagittaria at Woodbury, N. J., by Satterthwait and was determined by him as L. sordidus (Gyllenhal) and recorded as such under his Webster Groves No. 26558. A specimen taken at Stoughton, Mass., by Mrs. D. H. Blake bears the following nota- tion: “Found near Sagittaria latifolia whose root stocks were heavily infested by some insect.” Beutenmiiller (1890 and 1893) says that F. M. Chittenden found L. tuberosus LeConte, along with L. caudatus (Say )and L. appendiculatus (Boheman) while sweep- ing vegetation composed of Sagittaria and Carex. Mr. C. A. Frost has taken the species at Northboro, Mass., by sweeping vegetation along a river. Townsend (1885) records quite a number as having been taken along with L. callosus LeConte, L. frontalis LeConte, and L. nebulosus LeConte under old railroad ties lying on the ground and under pieces of wood in dry places during the early part of April. Blatchley and Leng (1916) say that it has been taken from the margins of ponds and along the beach of Lake Michigan, and that it usually occurs on sandy and muddy ground near water; also that it is often taken by sweeping aquatic plants such as Sagittaria and Carex. The species is sometimes taken at light.

Data on Distrrisution. The original description gives the dis- tribution as Michigan to Georgia. Blatchley and Leng (1916) add the territory northward into Quebec. We now know that it occurs as far west as Manitoba and North Dakota, and southward through Iowa, Missouri, and Oklahoma, into Texas. Specimens have been examined from the following localities:

There is an oblique dark mark centering on the fourth elytral interval at the anterior third, sometimes present only on that inter- val, other times longer and extending in some cases to include the second and sixth intervals. When this dark line is fully developed it extends posteriorly and toward the suture, reaching a little past the middle of the elytron; it extends anteriorly toward the humerus. The oblique line is often more strongly developed on the lighter specimens, and on some very dark individuals may not be at all evident. There is a tendency for the scales between the oblique lines to be of a slightly darker color. Beak moderately stout, slightly longer than the prothorax. Upper surface with a distinct sharp median carina, lateral carinae usually moderately developed, not sharp. Antennae slender, second segment of funicle twice as long as first, third distinctly longer than fourth. Head slightly convex, densely, moderately punctate, the punctures bearing short, slender scales; frontal fovea usually deep and elongate. Prothorax wider than long, ocular lobes moderately developed; sides nearly parallel for three-fourths their length, then strongly rounded to apex; base slightly arcuate; disk quite densely punctate with moderately large, - but very shallow punctures. Scutellum elongate, covered with slen- der scales. Hlytra emarginate at base; humeri oblique; slides slightly narrowed to apical fourth, then strongly rounded to apex; striae fine, slightly impressed, the punctures very small, elongate, each bearing a tiny seta; intervals sometimes almost flat, usually slightly convex, especially the odd ones; intervals each with a row of distant punctures bearing setae which are more evident on the de- clivity; third and fifth intervals with punctures confused instead of in a single row; posterior calli prominent. Ventral surface with sides of all the sterna, except seventh abdominal, rather thickly clothed

266 THE UNIVERSITY ScrENCE BULLETIN

with large, round scales; middle of third and fourth abdominal sterna clothed with round scales; middle of fifth and sixth ab- dominal sterna and all of the seventh clothed only with elongate scales or setae. Male with tips of elytra conjointly rounded or very slightly subacuminate; third abdominal sternum concave at middle. Female with tip of each elytron prolonged into a short conical proc- ess; third abdominal sternum convex; seventh abdominal sternum with a slight depression in each posterior corner and with a short, rather deep median groove at the posterior part of the sclerite.

Notes oN SyNonyMy. LeConte (1876) discusses L. distingwendus (Gyllenhal) as a synonym of L. sordidus (Gyllenhal), stating that it “seems to differ from the type only by smaller size and slightly irregular elytral puncturing; similar variations occur in other spe- cles.”

L. obliquus LeConte has also been found to be a synonym of L. sordidus (Gyllenhal). In his description of the species LeConte gives no distinguishing features by which it may be separated from L. sordidus (Gyllenhal). Specimens from Texas, Louisiana, Ala- bama, and Florida have been found which agree with the types of L. obliquus LeConte which are from Texas. Occasional larger speci- mens from the northern states also compare with the types of L. obliquus LeConte. These specimens are somewhat larger than most of the northern individuals. The larger northern specimens and most of those from the south usually tend to be a little lighter in color. They may have the beak a little more distinctly carinate and suleate and the frontal fovea a little deeper and more elongate. There is also a tendency for the alternate intervals of the elytra to be more strongly convex in the larger southern specimens. None of these characters is constant, however, and a careful examination of rather long series has indicated that the northern and southern specimens belong to the same species. Individuals can be picked out which are very different in size and seem to differ considerably even in regard to morphological characters. By studying additional material the variation within the species soon fills in a multitude of intermediate forms between the two extremes which had been segregated. L. distinguendus (Gyllenhal) and L. obliquus LeConte, the two synonyms of L. sordidus (Gyllenhal), have been erected on individuals representing the extremes of variation found within the species.

Notes on Types. JL. sordidus (Gyllenhal) and L. distinguendus (Gyllenhal) are the only names proposed in this genus for which

HENDERSON: THE GENUS LISTRONOTUS 267

type material of some sort has not been studied, with the exception of the two species described by Say, the types of which have been lost or destroyed. Horn and Kahle (1935) state that the Gyllenhal Collection is deposited in the museum at Uppsala, Sweden. The types of L. obliquus LeConte are in the LeConte Collection in the Museum of Comparative Zodlogy at Harvard College. There are two specimens, both females, which bear the locality label, “Tex.”

REMARKS AND ComPaARATIVE Notes. JL. sordidus (Gyllenhal) is very closely related to L. tuberosus LeConte and sometimes, es- pecially in the case of males, the two species are very difficult to separate on external characters. The males can be readily separated by the different shape of the apex of the median lobe of the genitalia, and the females can be separated by the shape of the eighth ab- dominal sternum. The females of L. sordidus (Gyllenhal) may be distinguished by the shorter and usually stouter appendages of the elytra and by the less convex seventh abdominal sternum. The beak of L. sordidus (Gyllenhal) is usually more strongly carinate and suleate, while in L. tuberosus LeConte the beak is usually smooth, with the median carina faint or absent, and the lateral grooves obsolete. In L. sordidus (Gyllenhal) the elytra are smooth, or have the alternate intervals more convex. In L. tuberosus Le- Conte the intervals are of about equal convexity, but the elytra are roughened by transverse wrinkles. The anterior margin of the elytra of L. tuberosus LeConte is somewhat reflexed, while in L. sordidus (Gyllenhal) it is more rounded.

BrotocicaL Notrs. Nothing is known of the life history or food plant of this species. It is reported to have been taken in a cotton field at Cameron, La., on September 10, 1904, by Wm. Laurents. Since no other records are known of its occurrence on cotton it probably has no connection with this plant, but was merely a chance visitor in the field when it was captured. A specimen was taken on Sagittaria by H. P. Léding, at Mobile, Ala., on June 29, 1920. It has been taken at light in Louisiana. It was found in the stomach of Bufo valliceps at New Orleans, La.

Dara on Distripution. JL. sordidus (Gyllenhal) and L. dis- tinguendus (Gyllenhal) were both described from boreal America. LeConte (1876) gives the range as Massachusetts to Georgia. Blatchley and Leng (1916) list “Ontario and New England to Lake Superior, south to Georgia and Texas.” Quebec is added to the Canadian localities. In the United States it has been found to extend south into Florida and as far west as Colorado. The records of distribution of the specimens examined are as follows:

Listronotus manifestus new species (Plate XXXV, fig. 4; Plate XXXVI, fig. 8)

Length, 7 to 9mm. Elongate-oblong. Body black. Densely covered with imbricated scales which are dark brown, light brown, and fulvous, sometimes with a cupreous or brassy tinge. Color pat- tern usually not definitely marked, but may be sharply defined in some individuals. In these cases the first three and last three in- tervals of the elytra and most of the prothorax are covered with dark-brown scales. On the disk of the prothorax there is a narrow median vitta and wider, irregular, lateral vittae of fulvous scales. On the elytra there is a longitudinal band of these light scales on the fourth to the eighth intervals and extending posteriorly to the tips of the elytra, crossing the last three intervals there. This light band is interrupted by the dark-brown scales for a short distance on the fourth interval just a little in front of the middle and on the seventh and eighth intervals just behind the middle. Beak slightly longer than prothorax, rather stout, strongly curved; median carina fine and sharp, sides of beak rounded, smooth, lateral grooves and sulci not at all indicated; upper surface densely and finely punctate, thickly covered with small, rounded scales. Head flattened between the eyes, very densely and finely punctate; upper part with narrow scales; rounded scales between the eyes, becoming larger on the frontal fovea, which is deep. Antennae moderately slender; second segment of funicle one-half longer than first, third segment elongate, longer than fourth. Prothorax one-fifth to one-fourth wider than long; ocular lobes much larger than in any of the other species of this group, enlarged and produced ventrally to form a ridge in front of each anterior coxa and causing the prosternum to have the appear-

ance of being deeply emarginate in front; prosternum sulcate at middle; sides of prothorax nearly straight, converging from base to apex; disk finely, densely, deeply, and cribrately punctate, thickly clothed with imbricated scales which are slightly larger than those of the elytra; only a very few open punctures on the disk bearing short inconspicuous setae. Scutellum elongate, thickly covered with tiny light-colored scales. Elytra elongate; moderately and angularly emarginate at base; humeri oblique; an angulate prominence just behind the humeri; sides gradually narrowed to apical fourth then strongly converging to the conjointly rounded apices; striae slightly impressed, finely punctate; intervals slightly convex; setae very small, not at all prominent; posterior calli obsolete. Ventral sur- face finely and densely punctate; everywhere thickly clothed with rounded scales except seventh (fifth visible) abdominal sternum where the punctures bear setae instead of scales. Legs moderately stout, squamose and setose; femora with a preapical band of light scales; tibiae with apical mucrones short and stout; front and middle tibiae with a row of minute acute teeth along their inner margins. Male with third (first visible) abdominal sternum broadly and deeply concave at middle; seventh (fifth visible) abdominal sternum slightly convex. Female with basal part of third (first visible) abdominal sternum convex, median posterior part slightly concave; seventh (fifth visible) sternum unmodified; seventh tergum deeply emarginate at apex.

REMARKS AND CoMPARATIVE Notes. This species is rather dis- tinct, but is probably most closely related to L. sordidus (Gyllenhal). It may be readily distinguished by the very large ocular lobes, the anteriorly converging sides of the prothorax, and the light band on the sides of the disk of the elytra. It may be separated from L.

sordidus (Gyllenhal) by the smoother sculpturing of the beak, by the obsolete posterior calli of the elytra, and the absence of the elevated alternate intervals.

ORIGINAL Description. “Blackish, covered with the usual scales, of a dirty-brown; beak feebly carinate, lateral grooves almost ob- solete; frontal fovea distinct. Prothorax as wide as long, sides strongly rounded, clothed with paler scales; surface coarsely and densely punctured; an indistinct paler dorsal stripe may also be traced. Elytra with deep punctured striae, and convex interspaces; posterior callus obsolete. Length, 7.5 mm.; .30 inch.

“Female. Last ventral with a large shallow rounded impression; elytra conjointly rounded at tip. Male wanting.

“One female, Georgia. Quite distinct by the more rounded pro- thorax. The funiculus of the antennae is as slender as in any of the preceding species; the setae of the elytra are rather more con- spicuous.”’

ADDITIONAL Description. Length, 5.5 to 8mm. Beak slender, slightly curved, about same length as prothorax; covered with rounded scales until a short distance behind insertion of antennae, shining and with only a few short slender setae from that point to apex; median carina fine, but distinct, partly covered by scales so that it does not appear to be quite as prominent in fresh specimens as in those with part or all of the scales rubbed off; coarsely and

rugosely punctate, the punctures covered by the scales so that fresh

272 Tue UnNIversity ScIENCE BULLETIN

specimens appear smooth; lateral sulci faint, also obliterated by scaly covering. Head convex, lower part very densely covered with scales, upper part clothed with setae; frontal fovea deep. Antennae slender, second segment of funicle not quite twice as long as first, third segment elongate, longer than fourth, and nearly as long as first. Prothorax one-fifth wider than long; ocular lobes prominent; sides strongly rounded; disk convex, densely and coarsely punctate; scales on disk noticeably larger than those of elytra and distinctly striated, not imbricated; a narrow median and indistinct oblique lateral vitta of paler scales; a number of rather long, slender, semi- erect setae arising from larger open punctures. Elytra elongate- oblong, about three times as long as prothorax; base rather deeply emarginate, humeri oblique; sides nearly parallel for two-thirds of their length, then narrowed to the conjointly rounded apices; striae deeply impressed, their punctures small and closely placed; intervals convex, thickly clothed with imbricated scales, each interval with a single row of rather long, semierect, light-colored setae, which be- come longer on the declivity. Male with third and fourth abdominal sterna sparsely and moderately coarsely punctate, slightly impressed at middle; seventh sternum sparsely and finely punctate, sometimes with a very broad and feeble transverse impression toward the apex. Female with third and fourth abdominal sterna moderately and sparsely punctate, slightly convex at middle; seventh abdominal sternum with a large, deep median impression, sometimes rounded, sometimes slightly transverse, usually shining and sparsely punc- tate; seventh tergum truncate at apex.

Norres on Synonymy. JL. cribricollis LeConte has been found to be a synonym of L. rotundicollis LeConte. According to the original descriptions about the only difference that can be expected in the two is that of size. The structure of the seventh abdominal sternum of the female is described in about the same way. An examination of the types proves that these two species are the same. I do not know why LeConte placed ZL. cribricollis LeConte among those species having the third segment of the funicle globose and equal to the fourth. It is in reality elongate and longer than the fourth segment.

Norrs on Types. The types of both L. rotwndicollis LeConte and L. cribricollis LeConte have been examined in the Museum of Com- parative Zodlogy at Harvard College. Both types are females, and bear the orange disk indicating the “southern states.” LeConte gives Georgia as the place of collection of both of these specimens. The

HENDERSON: THE GENUS LISTRONOTUS Pile

type of L. rotundicollis LeConte has the disk of the prothorax some- what rubbed. Beside the type in the LeConte Collection there is a female of L. frontalis LeConte, without any label. Beside the type of L. cribricolliis LeConte there are two additional specimens, the first a male L. frontalis LeConte from ‘Alamosa, Colorado,” and the second a specimen of L. oregonensis (LeConte).

BrotocicaL Norrs. Pierce (1907) records a species of Listronotus on cotton at Victoria, Tex., the species having been determined by him as L. setosus LeConte. A specimen upon which this record was based, determined by Pierce as setosus, has been examined, and in reality is L. rotundicollis LeConte. Mitchell and Pierce (1911) re- cord the species as having been taken on cotton at Victoria, Tex. Some of the specimens on which this record is based have been examined. It was taken at Goliad, Tex., by C. R. Jones, on cotton. L. rotundicollis LeConte was taken on spider lily by Mitchell in Victoria, Tex., on March 20. The species is often taken at light. Jones (1935) records a species which was questionably determined as L. rotundicollis LeConte as having been taken in beach drift in Virginia after a storm. One of the specimens taken, bearing the in- formation, “Va. Beach, Va., 10/18/32, Walker, Jones, & Brannon,” has been examined and definitely belongs to this species.

Data on DisrriputTion. This species has been recorded previ- ously from Virginia, Georgia, and Louisiana. We now know that the range extends as far north as Pennsylvania and southwest through Kentucky, Arkansas, Oklahoma, and Texas. Specimens examined have been as follows:

behind the humeri, then parallel for two-thirds the length, then narrowed to the conjointly rounded tips; striae fine, impressed, the punctures distinct, closely placed; intervals convex, each with a row of slender semierect setae which become longer and more erect on the declivity; elytra without transverse wrinkles; posterior calli very feeble; first intervals raised and more prominent in the region between the posterior calli, at the beginning of the declivity. Legs moderately stout; apical half of femora with a covering of rounded scales and slender setae, basal half with only short slender setae; tibiae with a very few scattered small scales and many long, whitish bristles; apical mucrones rather long. Male with third and fourth (first and second visible) abdominal sterna impressed at middle; all the abdominal sterna rather sparsely punctate, the punctures not all the same size, with very long, slender setae arising from the larger punctures; a few rounded scales along the sides of the abdominal sterna, more numerous on the third and fourth; seventh (last visible) sternum convex along the median half for its entire length. Female with third and fourth (first and second visible) abdominal sterna convex at middle; punctation and covering of abdominal sterna much the same as in the male except that the setae are not as long or as numerous and that there are more rounded scales present, often extending entirely across the fourth (second visible) abdominal sternum; seventh (last visible) sternum with a large semicircular area across the middle of the basal half, which is smooth and shining; a feeble impression across the entire width of the seventh (last visible) sternum just before the apex which is shghtly raised and has a semicircular apical emargination at the middle; seventh tergum broadly and shallowly emarginate at apex.

REMARKS AND CoMPARATIVE Notes. Related to L. scapularis Casey, but may be separated from it by the following character- istics: beak a little stouter, lateral carinae more prominent; disk of prothorax with more large punctures, and with setae longer and more prominent; base of elytra more deeply emarginate and humeri more oblique; elytra rounded behind the humeri and without the angulate prominences of L. scapularis Casey; elytral intervals more convex, first intervals more prominent at declivity of elytra, and posterior calli less prominent; seventh (last visible) abdominal sternum of male convex and that of female without the deep depression of L. scapularis Casey, and with the apical emargination narrower and deeper; tips of female elytra conjointly rounded instead of separately acuminate. The males may easily be separated by the shape of the median lobe and females by the shape of the eighth sternum.

Also resembles L. rotundicollis LeConte to some extent, but differs in the following respects: thicker and more strongly carinate beak; prothorax less constricted anteriorly and with coarser punctation on the disk; elytra more strongly emarginate at base; humeri more oblique. The seventh and eighth sterna of the females are different and the genitalia of the males are very different.

OricINAL Description. “Parallel and somewhat stout, moderately convex, black, densely clothed throughout with brown scales nearly uniform in color, on the pronotum slightly larger, but not obscuring the punctures and slightly paler in a feeble oblique line at each side and in the middle toward the base. Head a little less than one-half as wide as the prothorax, densely fulvo-squamulose, the eyes sepa- rated by nearly four times their own width; beak long, about as long as the head and prothorax, straight, bent downward and gradually

dilated toward the tip, tricarinate above, squamose and densely punctato-rugose throughout; antennae long and slender, inserted near the apex, the scrobes long, deep, coarse, straight, and horizontal, scape very long, slender, feeby enlarged distally, second joint of funicle greatly elongate, more than twice as long as the first and almost as long as the next four combined. Prothorax two-fifths wider than long, the sides subparallel, conspicuously and almost evenly arcuate, a little more convergent toward apex than base, the former three-fourths as wide as the latter, truncate, the ocular lobes well developed; base broadly arcuate; disk sparsely, moderately coarsely punctate, each puncture bearing a small, stiff hair. Scu- tellum circular, densely clothed with pale whitish scales. Elytra three-fifths longer than wide, between three and four times as long as the prothorax and nearly one-half wider; sides parallel and straight behind the post-humeral projection, outwardly oblique and straight from the base to the apex of the angulate prominence, gradually rounded in about apical third, the subapical umbones well marked; disk finely striate, the striae finely, feebly and indistinctly punctate; intervals flat, finely, sparsely punctate, each puncture bearing a small stout hair. Abdomen densely squamose on the two basal segments, thence coarsely pubescent with squamose sublateral areas to the apex; legs long, densely squamose and with short stiff sparse hairs, the scales paler toward the femoral apices. Length, 12.0 mm.; width, 5.0mm. (across the post-humeral angular promi- nences 5.5 mm.).

“Texas (El Paso). Mr. Dunn.

“This large and distinct species may be placed near callosus Lec., for the present, but is not closely allied to any other thus far de- scribed. The type is probably a female. Two specimens.”

ApDITIONAL Description. Length, 8 to12 mm. Thickly clothed with nearly uniform brownish scales, larger on prothorax, smaller and imbricated on elytra. In fresh specimens the following mark- ings of light scales may be observed: a narrow irregular oblique line at each side of the prothorax, and a short median line at the base; a wider irregular band on the elytra, covering the humeri and ex- tending caudad over the posterior calli. Occasionally there may be scattered small patches of light scales on the disk of the elytra. The extent of the light scales is variable and in some specimens there are very few present. On older specimens the light scales may be- come saturated with oil from the body, in which case they become dark or dirty, and the patterns are obliterated. Beak tricarinate

above, median carina prominent, sharp, smooth; lateral carinae less prominent, more rounded, closely punctate. Antennae with second segment of funicle about twice as long as first, third longer than fourth, second almost as long as next four combined,.as stated in original description. Head convex, finely and closely punctate, densely covered with elongate scales, becoming rounded in the area immediately surrounding the frontal fovea, which is deep and punctiform. Disk of prothorax closely, moderately coarsely punc- tate, each puncture closed by a seale; a few scattered punctures larger, open, and bearing short setae. The original description mentions only these latter punctures, not the smaller ones which are covered over by the scales. Base of elytra deeply emarginate. Female with tips of elytra separately, very slightly subacuminate; seventh abdominal sternum very slightly emarginate at apex, nearly truncate, with an oblong median transverse depression which is impunctate and somewhat shining at the middle.

Notes on Types. The types of this species are located in the Casey Collection in the United States National Museum, and have been examined. The type is a female from “Tex.” A paratype male is also labeled “Tex.” There is a third specimen in the series, a male, not a type, and without any locality label, although it is undoubtedly from Texas.

ReEMARKS AND CoMpPaRATIVE Notes. This species has been found confused in collections with L. callosus LeConte which it resembles. It may be readily distinguished by the prominent post-humeral pro- jections and the flat intervals of the elytra. The prothorax is relatively wider, being three-fifths wider than long while in L. callosus LeConte the prothorax is only one-fifth wider than long. The genitalia of the two species are very distinct.

BroLtoaicaL Norrs. This species has been taken at light.

1928. Listronotus callosus Blatchley, nec LeConte. Blatchley, Jr. N. Y. Ent. Soc., XXXVI, De 2a:

Length, 9 to 12.5 mm. Oblong, stout, black. Clothed with dark- brown and light-brown scales, the latter forming an irregular lateral vitta on the prothorax and extending onto the humeri of the elytra and sometimes to the posterior third of the elytra. In some in- dividuals these light-brown scales become almost cinereous. Beak moderately stout, very slightly curved, as long as the prothorax; upper surface distinctly tricarinate; lateral sulci very deep; surface rugulosely punctate; clothed with narrow scales. Head convex, densely punctate, clothed with narrow scales; rugose between the eyes and with the scales wider; frontal fovea very deep. Antennae moderately slender; second segment of funicle nearly twice as long as first; third segment very slightly elongate, not as long as first; fourth to seventh segments rounded. Prothorax slightly wider than long; ocular lobes moderately developed; sides nearly parallel at middle, strongly rounded at base, slightly constricted at apex; disk of prothorax more sparsely squamose than elytra, the scales much larger than those of the elytra but not imbricated; the surface densely and coarsely punctate, a few scattered larger punctures open and seta-bearing; sides of prothorax granulate-punctate. Scutellum elongate, clothed with tiny whitish setae. Elytra deeply emarginate at base; humeri right-angulate or very slightly oblique, prominent because of the deeply emarginate base of the elytra; rounded behind the humeri, sides parallel in the male, very slightly wider a little behind the middle in the female; striae not impressed, but coarsely and deeply punctate; intervals convex, the third and fifth usually very strongly so; elytra with a very rough appearance caused by numerous prominent transverse wrinkles; setae rather short, decumbent, not very prominent. Ventral surface sparsely and unevenly punctate with intermixed large and small punctures; sterna nearly bare at middle, having only a few short, slender, in- conspicuous setae, but with the sides rather thickly clothed with rounded scales. Legs rather slender; middle and hind femora with a preapical band of light scales; tibiae strongly mucronate at apex. Male with third and fourth (first and second visible) abdominal

sterna broadly coneave; seventh (fifth visible) sternum slightly convex; elytra conjointly rounded. Female with third and fourth (first and second visible) abdominal sterna very strongly convex throughout their entire width; seventh (fifth visible) sternum rather broadly and deeply transversely concave; seventh tergum broadly and shallowly emarginate at apex; tips of elytra separately acumi- nate.

Notes oN Types. Holotype male and allotype female, ““Home- stead, Fla., June, 1929, Darlington.” Six paratypes as follows: 2 females, “Homestead, Fla., June, 1929, Darlington”; 1 male, “Flagler Co., Fla., 11-18-30, D. B. Webb, Florida Fruit Fly Trap Surv.”; 1 male, “Paradise Key, Fla., 1V-1-25”; 2 females, ‘Royal Palm Park, Fla., 12-12-24, W. S. B.”

Holotype and allotype in the Museum of Comparative Zodlogy at Harvard College. Paratypes in the Museum of Comparative Zoology at Harvard College, the United States National Museum, the Francis Huntington Snow Entomological Collections at the Uni- versity of Kansas, and in the collections of H. C. Fall and Purdue University.

REMARKS AND ComPARATIVE Notes. This species appears to be somewhat related to L. callosus LeConte, but may be separated from it by the following characters: beak more strongly tricarinate; fourth segment of funicle of antennae not elongate; elytra with transverse wrinkles and the odd intervals not as strongly convex; posterior calli not at all prominent.

L. blatchleyi n. sp. appears to be most closely related to L. palustris Blatchley. The two species are very similar in many re- spects, but may be separated by the following characteristics: alternate elytral intervals less convex in palustris than in blatchleyi; beak equal in length to the prothorax in blatchleyi, longer than the prothorax in palustris; all the tibiae denticulate along the inner mar- gins in blatchleyi, hind tibiae not denticulate in palustris; elytra with transverse wrinkles in blatchleyi but not in palustris. The two species may be separated readily by the differences in the median lobes of the males or the eighth sterna of the females.

Blatchley (1928) refers to L. blatchleyi n. sp. under the name of L. callosus LeConte. Since Blatchley has collected the species and published on it, it is named for him.

Biotocicat Notes. Blatchley (1928), in referring to the two specimens of this species which were collected by him says, “Two females, each 13 mm. in length, were taken December 12, hibernat-

OrIGINAL Description. ‘“Elongate-oblong, robust. Black, above rather thickly clothed with pale brown, fuscous and silvery gray scales, the gray ones forming a narrow stripe each side of thorax and along the sides to beyond the middle of the elytra, covering also the meso- and metasternal side pieces and sides of ventral seg- ments, and forming a ring near apex of each femur; antennae, tibiae and tarsi dark reddish-brown. Beak rather stout, as long as thorax, distinctly tricarinate and quadrisuleate. Thorax short, convex, dis- tinctly wider than long, sides broadly rounded, disc coarsely, evenly and densely punctured, each puncture closed by a round scale, much larger than those of elytra. Scutellum small, rounded. Elytra but slightly wider at base than middle of thorax, humeri oblique, sides subparallel to apical third, then strongly converging to apex where they are conjointly rounded in male, but separately prolonged in short, obtuse processes in female; striae with very coarse punctures separated by their own diameters; first, third and fifth intervals convex, slightly elevated, the others flat; setae very short, visible only on the declivity. Fifth ventral of female broadly and deeply impressed. Length, 6.2-8.5 mm.

“Dunedin, Florida, Jan. 17-April 6; common beneath boards and other cover along the margins of ponds; mating Feb. 11 and April 1. Enterprise, Fla., May 25; LeConte collection, without name. Marion county and Enterprise, Fla., May 27; Horn collection, without name. Specimens sent to Doctor Chittenden were returned as L. sulcirostris Lec., but careful comparison with the type of that species shows palustris to differ widely in the secondary sexual characters of fe- male, as well as in the width, vestiture and punctuation of thorax.”

sulci deep, extending beyond middle of beak; upper surface rather thickly clothed with narrow scales and a few slender setae. Head convex; deeply and densely punctate; clothed with short stout setae; frontal fovea deep, with a small patch of rounded scales. Prothorax one-fifth wider than long; disk with a number of scattered large punctures bearing short, stout setae instead of rounded scales. Male with third abdominal sternum slightly concave; entire surface of seventh sternum convex, often with a short median longitudinal de- pression just before the apex. Female with third abdominal sternum slightly convex; seventh sternum with a moderately deep concavity across its entire width.

Nores on Types. The types of this species, a male and female, were found mating at Dunedin, Fla., April 1, 1915, and were col- lected by W. 8S. Blatchley. They are located in the Blatchley col- lection at Purdue University.

BriotoagircaL Notes. Several specimens have been taken from the stomachs of Bufo terrestris at Lake Kissimmee, Florida. There is a specimen of L. palustris Blatchley in the Harris collection in the Boston Museum of Natural History. It had not been determined as any species. A number on the specimen refers to the Harris cata- logue, where we find that the specimen was taken under the bark of a rotten oak in “E. Fla.,” by Doubleday.

284 THE UNIVERSITY ScIENCE BULLETIN

REMARKS AND CoMPARATIVE Notes. This species is fairly closely related to L. palustris Blatchley, but is much smaller, has the beak less coarsely sculptured, has the scales of a uniform color, and the elytral intervals are not convex as in L. palustris Blatchley.

BroLocicaL Notes. This species has been taken in some numbers from the stomachs of Bufo terrestris at Lake Kissimmee, Florida. A specimen from Ponchatoula, La., was collected on turnip on May 2. This species has been taken at light in Louisiana.

ORIGINAL Description. “Blackish, less elongated, covered with rounded scales, which are no larger on the prothorax; these scales are dirty brown on the elytra, and with a metallic lustre on the head and prothorax. Beak finely carinate, lateral grooves almost obsolete, frontal fovea deep. Prothorax very little longer than wide, broadly rounded on the sides, transversely impressed near the tip; lateral stripes and dorsal line indistinctly paler, punctures dense, of two sizes, the larger more distant. Elytra one-third wider than the prothorax, broadly emarginate at base, humeri rounded; striae strongly punctured, interspaces wide, nearly flat; tip conjointly rounded in both sexes. Length, 5.7-10 mm.; .23-.40 inch.

“Male. Last ventral not impressed; anal segment slghtly prominent.

“Female. Last ventral with three shallow impressions.

“Michigan, New York, Georgia, Texas. Stouter than L. nebulosus, and easily recognized by the above characters. The setae of the elytra are more obvious than usual.”

ADDITIONAL Description. Beak, about the same length as the prothorax, moderately stout; upper surface rounded, except for the

HENDERSON: THE GENUS LISTRONOTUS 285

sharp smooth median carina; surface rather densely, moderately punctate. Antennae with second segment of funicle about twice as long as first; third to seventh segments subglobose, third not longer than fourth and not as long as first. Disk of prothorax slightly wider than long; ocular lobes moderately developed; punctures dense, rather small, with a few scattered larger punctures bearing short, dark, stout setae instead of scales. EHlytra with striae rather fine, moderately punctate, the punctures not distant; intervals nearly flat, scales not imbricated, setae moderately long, dark, semierect, rather prominent on posterior part of elytra. Ventral surface of ab- domen not densely punctate; seventh sternum, however, more densely punctate than the others; punctures of varied size. Male with third and fourth sterna broadly and rather deeply concave at middle; seventh sternum nearly flat; disk of prothorax with only a slight median postapical impression. Memale with third and fourth sterna flat or shghtly convex; seventh sternum with three broad, feebly impressed longitudinal impressions, one median and the other two sublateral; disk of prothorax with a median postapical im- pression which is often rather deep. ?

Notes on Typrs. The types of this species have been examined. They are in the LeConte collection in the Museum of Comparative Zoology at Harvard College. There are four specimens in LeConte’s series of frontalis. The first one is a female labeled “Tex.” It is 9.5mm. long. There is a deep impression just behind the apex of the prothorax. The second specimen is from the “middle states” of LeConte and is probably the New York specimen mentioned in the original description. It is a male, and measures 6.2 mm. in length. The scales are slightly tinged with cupreous. The third of the series is a female and bears an orange disk indicating the “southern states,” probably Georgia. The fourth specimen in the series is labeled “S. Haven, Mich., 15.9.74.” It does not bear a type label, but is probably the specimen, or one of the specimens, upon which the Michigan record in the original description is based.

Biological notes. Sometimes taken at light. It was taken by Mitchell in Victoria county, Texas, in the early part of February, hibernating under pecan logs. Townsend (1885) found a number of L. frontalis LeConte in Louisiana, along with L. tuberosus Le- Conte, L. callosus LeConte, and L. nebulosus LeConte, beneath old railroad ties on the ground and under pieces of wood in dry places during the first part of April. Blatchley (1916) records the species as frequent along the beach of Lake Michigan and along the borders of ponds and ditches.

with numerous tubercles, each bearing a stout seta inserted in a small puncture on its dorsal surface; disk of prothorax usually with a feeble median longitudinal impression which is more distinct to- ward the base and apex than at the middle. Elytra rather stout; very slightly emarginate at base; humeri rounded; sides parallel to apical third, then broadly rounded to apex, which is rather blunt, or subtruneate; striae slightly impressed, the punctures small, closely placed, each bearing a tiny seta; intervals flat or slightly convex, the first two slightly depressed around the scutellum, the third usually more strongly convex at base, each interval with a row of short setae which are a little longer and very slightly clavate toward the apex of the elytra. Ventral surface densely, moderately punctate; sides of metasternum with a few rounded scales, the remainder of the ven- tral surface clothed only with slender setae. Male with third and fourth abdominal sterna broadly and feebly concave at middle. Female with third abdominal sternum slightly convex; seventh ster- num unmodified.

Notes on Syonoymy. The Listronotus latiusculus of American authors is L. oregonensis (LeConte). The type of Listroderes latiu- sculus Boheman has been examined and is a member of the genus Hyperodes. Under the name of Listronotus latiusculus (Boheman), LeConte, in 1876, says, “I refer this name to a species which occurs in the Middle and Southern States, and is by no means rare.” This statement is followed by a description of the species which must be known as Listronotus latiusculus LeConte, nec Boheman, since it does not refer to Boheman’s latiusculus, Listronotus latiusculus Le- Conte is a synonym of Listronotus oregonensis (LeConte), both names having been proposed for the same species. The latter name has priority by sixteen years. The type of Listroderes oregonensis LeConte has been examined, as has also the series of specimens on which the name Listronotus latiusculus LeConte is based.

In 1876 LeConte described Listronotus impressifrons. The types of this species have been examined and L. impressifrons LeConte is found to be a synonym of L. oregonensis (LeConte).

Blatchley described Listronotus rudipennis in 1916. Buchanan (1932) placed L. rudipennis Blatchley as a synonym of L. latiusculus (Boheman), at the same time expressing the opinion that there was some doubt as to whether L. latiusculus (Boheman) was the proper name for the species. He also suggested that if an examination of the type of Listroderes latiusculus Boheman showed that the name had been erroneously applied to the species in question, the name L. rudipennis Blatchley would become available. I have examined

HENDERSON: THE GENUS LISTRONOTUS 291

the type of L. rudipennis Blatchley and agree with Buchanan’s con- clusions regarding the synonymy of that species. I have also found, as was suspected by Buchanan, that the name latiusculus Boheman cannot be applied to this species. However, an examination of the type of L. oregonensis (LeConte) shows that it is the same species to which the name L. rudipennis Blatchley was applied, and since L. oregonensis (LeConte) was the first name applied to the species, it has priority over all others.

Notes on Types. The type of L. oregonensis (LeConte) is in the LeConte Collection in the Museum of Comparative Zodlogy at Harvard College. It is a female specimen and bears a blue disk indicating that it was taken in Oregon. The scales are nearly all gone, and the left elytron is broken from the body and mounted on a point on the pin beneath the body. There is a slight indication of the median thoracic impression mentioned by LeConte, but the appearance of the deepness of the impression is emphasized by the presence of some light scales at the bottom of the depression. These scales are the remnant of the lighter colored median vitta and were not rubbed off because they were protected by their location on the concave surface of the depression.

The types of ZL. impressifrons LeConte, and the specimens to which the name L. latiwsculus LeConte, nec Boheman was applied are also in the LeConte Collection at Harvard College.

The type of L. rudipennis Blatchley is in the Blatchley Collection at Purdue University.

The type of Listroderes latiusculus Boheman is in the Zoélogisches Institut at Halle, Germany.

Notes on Brotocy. The first mention of any biological informa- tion concerning this species was by Popenoe (1877). - He says that the species was common at Topeka, Kan., and that it was found under stones in the spring, and was taken on Peucedanum faenicula- ceum. Specimens taken by Popenoe at Topeka, Kan., have been examined.

The first known mention of the species causing any economic damage was made by Chittenden (1902) when he reported that it was discovered by Mr. F. C. Pratt, injuring parsley in Virginia. Some of the specimens taken from the roots of parsley by Mr. Pratt at Four Mile Run, Va., have been examined. Chittenden (1909) later reported on the life history and habits of the species.

Britton (1914) reported the “parsley stalk weevil” as causing damage to parsley in cold frames in Connecticut.

Chittenden (1924) again published on the “parsley weevil,” re-

porting damage which it had caused to carrots in New York and Washington, D. C. Some of the specimens which he mentions from Astoria, Long Island, New York, have been examined as have also some of those which he mentions as having been so abundant on parsley in Washington, D. C., in 1916. In this article Chittenden points out several times that these weevils were doing damage in dry soil, then says, “. . . it would naturally appear that the original supposition that this species was semiaquatic and that the attack to cultivated plants was accidental rather than otherwise should be modified. It is evident that we now have to deal with a species which is liable to be injurious to carrots or parsley at almost any time and place in its rather wide distribution.” At the end of the article he says, “There would naturally be some slight doubt as to whether the species reared by Dr. C. M. Weed in Ohio from Sagit- taria is the same as the one under discussion.” The source of con- fusion here has been due to the fact that Hyperodes solutus (Bohe- man), reared from Sagittaria by Weed, was determined as L. latius- culus (Boheman). When the true L. oregonensis (LeConte), the L. latiusculus of American authors, was found living in parsley and carrots in comparatively dry ground, the contrast with the supposed semiaquatic habits of the species presented a perplexing situation.

Chandler (1926) reports serious damage to carrots in Illinois by this species and says that it is apparently single brooded in Illinois.

Using the name L. rudipennis Blatchley, Harris (1926) gives a re- port of damage to carrots in Iowa by this species. A short discus- sion of the life history is given, and there are brief descriptions of the egg, adult, and habits of the adult. Harris states that there are probably three generations a year, and that hibernation is apparently in the adult stage.

Boyce (1927) discusses the serious damage caused to carrots by this weevil in the market gardens on Long Island, New York. His report of the life history covers one season’s study and is the most comprehensive that has been published. For a detailed description of the egg, larva, pupa, and adult, see page 816 of Boyce’s paper. A discussion of the life history is given on pages 816 to 819. Boyce (1927, pp. 814, 815, and 819) assumes that the species has changed its host plant and oviposition habits, but this is not the case; the previous records involving Sagittaria as a host plant, as has been pointed out before, are based on another species of weevil. During the course of the study, adults were reared from larvae taken from carrot, wild carrot (Daucus carota L.), curled-leaved parsley, hy- micha (Hamburg parsley, Apiwm petroselinum L.), and dill (Ane-

HENDERSON: THE GENUS LISTRONOTUS 293

thum graveolens L.). Three generations with overlapping broods were found to develop on Long Island.

Pepper and Hagmann (1938) report the carrot weevil as a pest of celery in New Jersey. They found three generations a year de- veloping on celery in New Jersey. A brief discussion of the life his- tory is given. A study was made of the food plants of the weevil. In addition to the plants mentioned by Boyce (1927), adults were reared from larvae found in the following plants; celery (Apium graveolens L.), broad-leaf plantain (Plantago major L.), and pa- tience dock (Rumex patientia L.). The following is quoted from Pepper and Hagmann (1938, p. 263): “Large numbers of arrow- head plants (Sagittaria variabilis) which grow along the drainage ditches in the celery fields were carefully dissected and no signs of grubs or their injury were present in these plants. This is contrary to the findings of Weed (1889) and others. Our survey, however, does not prove that L. latiusculus never attacks the arrowhead plant.” .

Although Pepper and Hagmann (1938) make the first report of the carrot weevil causing damage to celery, I have seen specimens from Kalamazoo, Mich., taken in May, 1934, which had been in- juring newly set celery. Specimens reared from celery at Hacken- sack, N. J., have also been examined.

There is another host plant to be recorded for L. oregonensis (LeConte). Specimens have been examined from Biloxi, Miss., bear- ing the Truck Crop Number 1159, which had been collected by M. M. High on turnip. The extent of feeding or damage, if any, is not known to me.

A specimen of L. oregonensis (LeConte) has been examined which had been reared from carrot by Satterthwait at Webster Groves, Mo. The species had been determined by him as L. sordidus (Gyllenhal) and was recorded as such under the Webster Groves Number 20549.

Harris (1926, p. 495) says that although the adults possess well- develeped wings and are apparently able to fly, no individual was ever observed to attempt to do so, but when disturbed would fall to the ground and lie motionless for a few moments before crawling away. Boyce (1927, p. 819) says, “The beetles have never been ob- served in flight although they have fully developed wings. An ex- amination of their wings furnishes some evidence that they do not fly except under the most favorable conditions, as the wings appear to be inadequate to efficiently support in flight a body of such size. A study of the infestations also indicates that they do not fly ac-

tively, since they were found only in carrots planted on soil that was infested the previous year.” Pepper and Hagmann (1938, p. 264) say, “As reported by Boyce (1927) and others, the adults are sluggish and invariably feign death when disturbed. There is no record in the literature of beetles having been observed in flight; however, the senior author has observed them on the wing. Four specimens which flew in the windows of a moving automobile were captured. Two adults were captured while in flight. From the above observations they seem to be poor fliers. Although the beetles fly, it is doubtful whether they migrate very far.” Specimens have been seen which had been taken at light in New Jersey, District of Columbia, Montana, and Louisiana. I have taken specimens at Lawrence, Kan., which had flown to lights, but from what distance they had come is not known.

A number of specimens of L. oregonensis (LeConte) have been found in the stomach of Bufo americanus in the northern states and of Bufo terrestris in the southern states, during the course of the food habit studies conducted by the Bureau of Biological Survey.

Data on Distripution. This species has a rather general dis- tribution over most of the United States. Specimens have not been seen from the southwestern states, but the species may be present there. Material has been examined from the following localities:

OricinaL Description. “Elongate-oval, strongly convex, black, the tibiae, tarsi, and antennae rufo-piceous; scales very dense, rounded and with radiating strigosity, only slightly larger on the pronotum but more distinct, cinereous-white in color with two large transverse areas of black at the base of the pronotum and two smaller and feebiler at the middle, the elytra with numerous isolated or partially anastomosing black spots throughout the extent; head densely, the beak more sparsely clothed with short, narrow squam- ules. Head three-fifths as wide as the prothorax, without a fovea but with a rounded spot of pale scales between the eyes, the latter re- motely separated; beak short and stout, not as long as the prothorax, bent downward and feebly dilated toward tip, finely, densely, ru- gosely punctate, with a single fine and feeble dorsal carinula; an- tennae rather short and thick, inserted at outer third or fourth, the second funicular joint not quite twice as long as the first and but slightly longer than the next three, the third longer than the fourth. Prothorax small, slightly wider than long, the sides arcuate; apex truncate, more than three-fourths as wide as the base, which is but feebly arcuate-truneate; ocular lobes moderately developed; disk evenly convex, finely, sparsely punctate, each puncture with a small

suberect stout hair. Seutellum small, not conspicuous. Elytra one- half longer than wide, scarcely three times as long as the prothorax and one-half to nearly two-thirds wider, parallel and straight at the sides, gradually obtusely rounded behind, humeri rounded to the prothorax, exposed at base; subapical umbones obsolete; disk finely striate, the striae very finely, scarcely distinctly punctate, the intervals feebly convex, finely, sparsely punctate, each puncture bearing a stout erect and strigilate hair. Abdomen thinly clothed with short, stout hairs, squamose toward the sides, strongly and closely punctate; legs moderately long, the femora more densely squamose and swollen distally but narrowed near the tip; hairs short, erect and sparse. Length, 5.3-6.5 mm.; width, 2.25-2.85 mm.

“Colorado (Denver). Mr. Hugo Soltau.

“A small but distinet species, quite conspicuous in maculation; it was taken by Mr. Soltau in considerable numbers. It may be placed near rotundicollis in the arrangement recently proposed by LeConte (Proc. Am. Phil. Soc., XV, p. 128).”

ADDITIONAL Description. Length, 5 to 7 mm. The relative amount of the light and dark scales varies to a considerable extent. Some examples are found in which the light scales on the prothorax form a narrow median vitta and broader lateral markings, with the greater part of the disk covered by two broad, longitudinal bands of black seales. Other specimens have been seen which had the entire prothorax covered with light scales, with the exception of a very small patch of dark scales on each side of the middle at the base. All degrees of development of the dark bands have been observed between the two conditions represented by the extremes which have been described. The darker forms are predominant, and the ob- literation of the dark bands begins at the apex of the prothorax and progresses toward the base. Beak with a median carina which may sometimes be very prominent and sharp; lateral carinae sometimes slightly evident; equal in length to the prothorax. Head very densely, coarsely, and rugosely punctate; frontal fovea rather deep, and covered with a small spot of rounded light-colored scales which contrast strongly with the shining black surface of the beak and ~ the slender setae of the head and beak. Third segment of funicle of antennae only very slightly, if any, longer than the fourth. Pro- thorax one-fifth to one-fourth wider than long; sides usually rather strongly rounded, slightly constricted at apex, broader at base than apex; disk convex, often with a feeble median sulcus, and usually slightly constricted just before the apex; disk thickly clothed with

scales which are very slightly larger than those of elytra; surface more finely and densely punctate and granulate than in L. oregon- ensis (LeConte). Male with all of median portion of third ab- dominal sternum and basal part of fourth sternum concave. Female with third and fourth sterna flat; seventh sternum unmodified.

Nores on Types. The type of L. tessellatus Casey has been ex- amined. It is a female labeled ““Denv., Col.” and is located in the Casey collection in the United States National Museum. There are also six paratypes which bear the same label. There is another specimen labeled “Cheyenne, Wyo., 4/19.89,’ which has been de- termined by Casey as tessellatus.

REMARKS AND ComparaTIVE Notes. L. tessellatus Casey is treated here as a subspecies of L. oregonensis (LeConte). The subspecies differs from the species mainly in the color of the body and scales. The body is nearly black and the scales lack all cupreous tinge, be- ing either black or dirty white. The beak is a little stouter and more convex on the upper surface, giving it the appearance of being bent downward at the tip. The median carina of the beak is more prominent and the basal portion of the beak and the front of the head are more densely, deeply, and rugosely punctate than in L. oregonensis (LeConte). The eighth sternum of the female and the genitalia of the male are the same in the subspecies as in the species.

Data on DistrrputTion. This subspecies has a very interesting distribution. I have seen specimens from six localities, extending from Denver, Colorado, to Medicine Hat, Alberta. These six points are all just east of the continental divide, and a line drawn through these points curves westward as it extends north, the curve corre- sponding almost exactly to that of the continental divide. Speci- mens have been examined as follows:

OricgINAL Description. ‘Elongate, subparallel; piceous, upper part of head, prothorax and elytra densely clothed with metallic scales, the underside of head, afterbody and legs less densely cov- ered, scales of the base of head, pronotum and elytra golden brown except for two linear patches at the side of pronotum posteriorly, and most of the fourth, fifth and sixth elytral intervals, which are silvery green, the scales of beak, legs and underside of body greenish. Beak robust, moderately convex above, nonsulecate and without carinae except at times a faint median one near apex, a well marked though small fovea on the front between the eyes, the scales of head slightly elongate; antennae with the funicle moderately slender, the third and following segments rounded, subequal, second one and a half times as long as first. Prothorax barely broader than long, ocu- lar lobes but moderately prominent, sides arcuate, slightly con- stricted near apex, disk densely and coarsely though shallowly punc- tured, in fresh specimens entirely concealed by the scales, the scales but very little larger than those of the elytra. Elytra less than twice as long as broad, broadly emarginate at base, sides parallel from rounded humeri to apical fourth, thence broadly rounded to suture; striae and strial punctures fine; intervals wide and flat; setae fine and short, though conspicuous especially on apical declivity. Length, including beak, 6.5 mm.; breadth, 2.5 mm.

“Holotype (No. 2508 Mus. Calif. Acad. Sci.) and one paratype in my collection, taken near Sobre Vista, Sonoma county, Califernia, May 8, 1910, and April 30, 1910, by Mr. J. August Kusche.

“This very attractive species, like the preceding, belongs in Le- Conte’s second group and should be placed somewhere near Listrono- tus teretirostris Lec., the smaller specimens of which it equals in size and also resembles in its robustness and general parallel form. It differs from this in coloration, in lacking the evident rostral carinae, in having a broader prothorax, the elytral apices more suddenly and broadly rounded and the elytral striae and strial punctures finer. I believe that there is no marked difference between the sexes.”

AppitionaL Description. Length, 5.7 mm. Beak about the same length as the prothorax. Prothorax finely granulate-punctuate; scales of disk narrower than those on sides. Ventral surface very

finely and densely punctate; thickly clothed with setae. Female with third abdominal sternum slightly concave in median portion of posterior half; seventh sternum unmodified.

Notes on Types. The paratype of L. elegans Van Dyke has been examined. It is a female collected at Sobre Vista, Sonoma county. Cal., April 30, 1910, and was loaned to me from the collection of the author. The holotype is in the Museum of the California Academy of Science.

REMARKS AND CompPaRATIVE Notes. The single female paratype is the only specimen of this very distinct species which I have seen.

OriGINAL Description. “Elongate, blackish, clothed with scales, mottled brown and dark, on the head with a metallic lustre. Beak feebly carinate and sulcate as usual. Prothorax longer than wide, sides feebly rounded for two-thirds the length, then more rounded to the tip; scales small, a bifurcated lateral vitta, and an interrupted dorsal line paler; punctures dense and deep.

Length, 9.5 mm.; .375 inch.

“Female. Last ventral slightly impressed; elytra conjointly rounded at tip.

302 Tue UNtIversiry ScreENCcE BULLETIN

“One female, Missouri. Easily recognized by the elongate form and mottled color.”

AppITIONAL Description. Length, 6.5 to 9mm. Beak stout, thick, slightly curved on upper side; slightly shorter than prothorax; a little shorter and thicker in the male than in the female; usually with a very sharp, smooth median carina; lateral carinae sometimes rather prominent; upper surface densely rugulosely punctate, clothed with a few narrow scales and slender setae. Antennae stout; second segment of funicle about one-half longer than first; third segment of funicle nearly rounded, not elongate. Head convex, densely punc- tate, clothed with slender setae; frontal fovea usually rather deep, with a small patch of rounded scales. Prothorax as wide as long, not longer than wide, as is stated in the original description; ocular lobes moderately developed; sides broadly rounded, widest at middle, slightly wider at base than at apex; disk densely punctate; a number of scattered punctures are much larger and deeper, and bear short, slender setae instead of rounded scales as do the other punctures. Legs stout. Ventral surface moderately punctate, large and small punctures intermixed; sparsely clothed with small scales, except median part of seventh abdominal sternum. Male with basal portion of third abdominal sternum slightly depressed; seventh sternum slightly convex, more densely and finely punctate than the other sterna. Female with seventh sternum very densely and finely, slightly rugulosely punctate; a transverse concave preapical area.

Nores oN SynonyMy. An examination of LeConte’s types shows that L. nebulosus LeConte and L. sulcirostris LeConte are both the same species. Both species were described in 1876 in the same paper, but L. sulcirostris LeConte appears on page 132 and L. nebulosus LeConte on page 133, giving the former name page priority. L. nebulosus LeConte, however, is the name which is in common usuage. The type specimen is also more typical of the species than are the two types of L. sulcirostris LeConte, which are abraded and represent extremes of variation found within the species. For these reasons the matter of page preference is being disregarded; L. nebulosus LeConte is retained as the name of the species, and L. sulcirostris is made the synonym.

_Nores on Types. The type of L. nebulosus LeConte bears a yel- low disk indicating the “western states,’ and the original descrip- tion gives Missouri as the locality. The specimen is a female, and is very typical of the species.

The types of L. sulcirostris LeConte, a female and.a male, bear

HENDERSON: THE GENUS LISTRONOTUS 303

orange disks indicating the “southern states,’ Georgia being the locality given in the original description. These specimens have the lateral carinae of the beak rather prominent, but an examination of a number of specimens of L. nebulosus LeConte will show that this is not an uncommon variation within the species. The female type of L. sulcirostris LeConte has the seventh sternum of the ab- domen more strongly impressed than the average condition found in the species.

The types of L. nebulosus LeConte and L. sulcirostris LeConte are in the LeConte collection in the Museum of Comparative Zoology at Harvard College.

BrotocicaL Norres. Popenoe (1878) stated that this species oc- curred at Topeka, Kan., with L. caudatus (Say) on Sagittaria. This record is probably based on a misdetermination, for I have seen a male specimen of L. caudatus (Say) from Topeka, Kan., which had been determined by LeConte as L. nebulosus LeConte. Since the species actually does occur in this locality, the erroneous record of locality 1s inconsequential, but we must regard as questionable the record of the occurrence of L. nebulosus LeConte on Sagittaria.

Townsend (1885) records the species as being quite numerous in Louisiana with L. twberosus LeConte, L. callosus LeConte, and L. frontalis LeConte, beneath old railroad ties on the ground and under pieces of wood in dry places during the first part of April.

The species was found hibernating under a pecan log in Victoria county, Texas, on February 3, by J. B. Mitchell.

L. nebulosus LeConte is frequently taken at light.

Data on Distripution. The range of this species seems to be limited mostly to the central states, extending from Texas and Louisiana, northward to Indiana, Illinois, and Wisconsin. I have examined specimens from the following localities:

Listronotus similis new species (Plate XXXVI, fig. 1)

Length,6to10mm. Elongate-oblong. Black to piceous. Covered with dark brown and light seales, the light ones sometimes with a faint pearly lustre; scales somewhat larger on the prothorax and slightly imbricated on the elytra; arrangement of the light scales variable but usually with indistinct lateral vittae on the prothorax and a humeral spot on the elytra, with varied amounts of pale scales scattered over the elytra. Beak short, stout, shorter than the prothorax; median carina strongly elevated, smooth, shining; punc- turation coarse and deep. Antennae stout, thicker than in any of the closely related species; second segment of funicle about one- half longer than the first, third segment rounded, fourth to seventh segments stout, the outer segments slightly transverse. Head densely punctate, more coarsely so between the eyes, each puncture bearing a small seta; frontal fovea deep, covered with a small patch of large, light-colored seales. Prothorax slightly wider than long; ocular lobes moderately developed; sides of prothorax evenly and rather strongly rounded; disk coarsely and rather densely punctate, each puncture just covered by a scale, a few scattered punctures larger and bearing short, slender setae instead of scales. Scutellwm slightly elongate, densely covered with tiny light-colored setae. Hlytra rather deeply emarginate at base; humeri right-angulate; sides gradually narrowed from the base to the apical fourth, then strongly curved to the conjointly rounded apices; striae only very slightly impressed, the punctures moderately coarse and not deep; intervals nearly flat, smooth, the setae inconspicuous on the disk, longer and stouter on the declivity; subapical umbones obsolete. Legs stout, especially the femora, which are strongly clavate; tibiae slightly enlarged at apex; apical mucrones of tibiae moderately long, those on the front tibiae of both sexes with a small acute tooth at the

base; hind tibiae, especially of the male, with a rather dense brush of yellowish hairs along the inner margin of the apical half. Male with the third (first visible) abdominal sternum slightly concave at the middle; third and fourth (first and second visible) abdominal sterna coarsely punctate, most of the punctures bearing large scales, a few punctures on the sides, more on the median part of the sclerites, bearing very slender scales or setae; fifth to seventh (third to fifth visible) sterna very finely and densely punctate, clothed only with short slender setae; seventh sternum strongly convex. Female with third (first visible) abdominal sternum very shghtly convex at the middle; all of the abdominal sterna with broad scales only at the middle; seventh (fifth visible) sternum with punctures smaller and more closely placed, very finely and densely punctate at the extreme apex; seventh sternum with a dis- tinct transverse subapical impression.

Paratypes in the Museum of Comparative Zo- ology, the United States National Museum, the Francis Huntington Snow Entomological Collections at the University of Kansas, and in the collections of the Illinois Natural History Survey and at College Station, Texas.

REMARKS AND CompPArRATIVE Notes. This species is extremely closely related to L. nebulosus LeConte. The internal genitalia of the males of the two species, although quite distinct, are very similar and clearly demonstrate the close relationship. From a study of the allotype, which is the only female of this species that I have seen, it is impossible to distinguish any significant difference in the eighth sterna of the females of the two species. It is possible that with more specimens available some distinguishing characters could be detected.

Because of the difference in the male genitalia the separation of males of L. similis n. sp. and L. nebulosus LeConte is easily made from dissections. Separation of the two species is not so easy on the basis of external characters. Because of the close relationship and the natural variation within a species, the use of any one character

20—2181

306 Tue UNIvERSITY SCIENCE BULLETIN

may not always be sufficient to definitely separate the two species. A combination of characters has been worked out, however, which will serve to separate them. In an examination of the specimens at hand, L. similis n. sp. has been found to have a small acute tooth at the base of the apical mucro of the front tibia in both the male and the female. This tooth is absent in L. nebulosus LeConte. The prothorax of L. similis n. sp. is usually slightly wider than long and has the sides rather strongly rounded. The prothorax has the ap- pearance of being wider and larger than in L. nebulosus LeConte, where it has the sides more broadly rounded. In L. nebulosus Le- Conte the prothorax is as long as wide, or sometimes slightly longer than wide. In L. similis n. sp. the width of the beak at the point of insertion of the antennae is more than nine-tenths of the width of the interocular space directly across the center of the frontal fovea. The beaks of the males are usually wider than those of the females, and in some males the two measurements just described have been equal. In L. nebulosus LeConte the width of the beak at the point of insertion of the antennae is usually less than nine-tenths of the width of the interocular space across the center of the frontal fovea. In comparing the two species L. stmilis n. sp. appears to have stouter antennae, as well as shorter, heavier legs, with more strongly clavate femora.

AppITIONAL Description. Length, 4.2 to7 mm. Elongate-oblong. Color reddish-brown, elytra usually with small, black markings near the middle on the second and third intervals, sometimes ex- tending obliquely forward to the humeri. Rather thinly clothed with small testaceous scales which may become imbricated on the posterior half of the elytra. A narrow median and a broader ir- regular sublateral vitta on the disk of the prothorax of lighter scales. Posterior third of elytra often thickly clothed with the same lighter scales, or sometimes the lighter marking confined to a spot at the beginning of the declivity between the third or fourth intervals, the declivity beimg covered with darker scales. Beak moderately thick, slightly curved on upper surface; slightly longer than prothorax; median carina fine, sometimes obsolete except at apex; sometimes with portion of beak between lateral carinae slightly concave to point of insertion of antennae; upper surface finely punctate, thinly clothed with very narrow scales. Head con- vex, densely punctate, clothed with very narrow scales; frontal fovea distinct. Antennae moderately stout; second segment of funicle nearly twice as long as first; third to seventh segments rounded. Prothorax slightly wider than long; ocular lobes promi- nent; sides slightly rounded, somewhat constricted at apex; disk densely and moderately coarsely punctate; scales larger than those of elytra, with a few narrow scales intermixed; disk sometimes with a fine median carina which may, however, sometimes be rather prominent; this carina abbreviated at base and apex. Scutellum slightly elongate. Elytra slightly arcuate at base; humeri rounded; striae fine, their punctures coarse and close-set; first two intervals depressed around scutellum, the strial punctures very coarse in this region; intervals flat or very slightly convex; setae very short, not

conspicuous. Ventral surface with metathoracic sternum and third and fourth abdominal sterna usually black or rufo-piceus; densely, moderately punctate; partially clothed with slender setae except for a few rounded scales on the sides of the metathoracic sternum and third and fourth abdominal sterna. Male with third and fourth abdominal sterna broadly concave at middle; elytra conjointly rounded. Female with third and fourth abdominal sterna convex; seventh sternum unmodified; tips of elytra normally prolonged into short, slender, parallel, cylindrical processes. The processes of the elytra are variable in their extent of development, sometimes being very short and occasionally entirely absent.

Notes on Synonymy. This species has a wide distribution and displays a great deal of variation. Several synonyms have been created as a result of this variation. Listronotus floridensis Blatch- ley, Listronotus leucozonatus Chittenden, and Listronotus impressus Van Dyke are now to be considered as synonyms of Listronotus appendiculatus (Boheman). Type material of all these names has been studied. The conclusions in regard to synonymy have been formed only after careful examination of the types and long series of specimens. A very few individuals can be segregated into what might appear at first to be different species. By studying additional specimens, however, intermediate forms are found, and it is im- possible to find any character or set of characters which will serve to separate even the majority of the specimens into groups.

Notes on Types. The type of L. appendiculatus (Boheman) is in the museum at Stockholm, Sweden, and has been exanimed. It is a female and was collected in Pennsylvania.

The type specimen and type series of L. floridensis Blatchley have been examined. These specimens are in the Blatchley collection at Purdue University.

The type and several paratypes of L. leucozonatos Chittenden have been examined. These specimens are in the United States National Museum.

Through the kindness of Dr. E. C. Van Dyke I have been supplied with a female paratype of L. impressus Van Dyke, which is to be deposited in the Francis Huntington Snow Entomological Collections at the University of Kansas. Another female paratype has been ex- amined in the United States National Museum. The type and other paratypes are in the Museum of the California Academy of Science.

REMARKS AND CoMPARATIVE Notes. An indication of the amount of variation found within this species has already been given. The

310 Tue UNIVERSITY SCIENCE BULLETIN

variation in the tips of the female elytra is comparable to the situa- tion found in L. squamiger (Say), except that there the elytra are usually rounded, while in L. appendiculatus (Boheman) they are usually prolonged into short processes.

There is also some variation in the amount of black found on the elytra and on the ventral surface. A series of specimens from Creston, British Columbia, has a great deal of black marking on the body. One specimen has the black fascia of the disk of the elytra extending laterally to the sixth intervals; has a black bar along the median third of the elytra on the seventh and eighth in- tervals; and has the greater part of the abdominal sterna black.

BrotoaicaL Norrs. Beutenmiiller (1890 and 1893) gives the fol- lowing note concerning this species; “Mr. F. M. Chittenden found L. tuberosus, L. caudatus and L. appendiculatus while sweeping a small patch of aquatic plants composed ‘entirely of Sagittaria and a species of Carex. L. appendiculatus, it is said, was found by Mr. William Julich breeding in the lower parts of the stems of some species of reed.” Webster (1894) recorded it as attacking cabbage in Ohio, gouging out cavities in the stems of young plants and later attacking the bases of the larger leaves. Smith (1910) records this species from New Jersey, stating that it was commonly taken in winter by sifting. Blatchley (1919), using the name L. floridensis Blatchley, records the species as having been taken in numbers on March 2, from flowers of Sagittaria. Blatchley (1928), again using the name L. floridensis Blatchley, says, “This has proved to be a common species throughout southern Florida, scores having been taken at Royal Palm Park in April on flowers of arrowhead along the margins of the everglades.” The specimens described by Van Dyke (1929) were taken from rice paddies in California.

The species has been taken in August at Waldoboro, Maine, on Sagittaria latifolia: It was bred from Sagittaria by Criddle at Treesbank, Manitoba. At Creston, British Columbia, it was taken on Sagittaria arifolia and on flood debris, the altitude being given as 1,750 feet. It was taken on Chelone glabra by D. H. Blake at Stoughton, Mass. It was taken on Nelumbo in Texas on May 17, 1906, by F. C. Pratt, and had been determined by W. D. Pierce as L. latiusculus (Boh.). Darlington found it in late March at Arling- ton, Massachusetts, in moss roots. It has been taken in Louisiana and the District of Columbia at light.

The lack of records from the western states may be due to lack of material from that region rather than the absence of the species, since it has been seen from Wyoming, British Columbia, and California.

ReMARKS AND Comparative Notes. This species is closely re- lated to L. oregonensis (LeConte), but may be distinguished from it

HENDERSON: THE GENUS LISTRONOTUS B15

by the more strongly carinate and suleate beak, the coarsely and rugosely punctate head, the large cribrate punctures of the disk of the prothorax and the absence of tubercles, the characteristic mark- ing of the apical portion of the elytra, the more coarsely punctate ventral surface, and the modification of the seventh, (fifth visible) abdominal sternum of the female. The eighth sternum of the female and the internal genitalia of the male are quite different in the two species.

BrotoaicaL Nores. A number of specimens of this species have been taken from the stomachs of Bufo terrestris at Lake Kissimmee, Florida. The species has also been taken at light on February 28, at Homestead, Florida.

Data on Distrripution. Known only from Florida.

covered with rounded scales; frontal fovea deep. Antennae slender; second segment of funicle only one-half longer than first; third seg- ment very slightly elongate. Prothorax one-fifth wider than long; sides strongly rounded at base and apex; ocular lobes moderately large; disk sometimes with a faint median carina, abbreviated at base and apex; surface roughly granulate-punctate, thickly covered with scales which are much larger than those of the elytra, are slightly convex, and are often polygonal rather than rounded; a few scattered, very long, stout setae arising from punctures at the apices of small tubercles. Scutellwm round, often elevated; thickly covered with small grayish scales. Elytra with striae fine, not deeply im- pressed, but strongly punctate, the punctures close-set; intervals con- vex, the odd ones more strongly so. Ventral surface coarsely and somewhat sparsely punctate, with rounded scales at sides of meta- thoracic sternum and third, fourth, fifth, and sixth abdominal sterna; elsewhere with very short setae. Male with third abdominal sternum broadly and deeply concave. Female with third abdominal sternum flat or very slightly convex; seventh sternum with a narrow but very deep longitudinal groove beginning before the middle and extending to the apex, causing it to be strongly notched when viewed from the end; seventh tergum very deeply emarginate, the emargination fitting around the notch of the seventh sternum.

Nores on Types. The types of L. setosus LeConte have been examined, and are located in the LeConte collection in the Museum of Comparative Zoédlogy at Harvard College. The first type is a female from “Cedar Keys, Fla.” The second type is a female from “Tampa, Fla.” The third type is a male bearing an orange disk, and is probably from Georgia, since that state is given as a locality in the original description. There is a fourth specimen in the series, a male, without a type label, but with the label, “Fla.”

BrotoaicaL Norrs. Blatchley and Leng (1916) recorded the species as being “frequent beneath boards along the margins of ponds and on the flowers of Sagittaria.” Pierce has recorded L. setosus LeConte as occurring on cotton at Victoria, Texas, May 23. A specimen upon which this record is based has been examined and is not L. setosus LeConte as determined by Pierce, but is L. rotundi- collis LeConte.

Data on Distrisution. Most of the specimens examined have been from Florida. I have seen three specimens, however, from the northern states, one from Massachusets, and two from New York City. This northern distribution may appear to be peculiar,

HENDERSON: THE GENUS LISTRONOTUS 317

but there is a region, especially around Martha’s Vineyard, Massa- chusetts, where a number of typically subtropical forms of plants and animals have been found. These forms, as in the case of ZL. setosus LeConte, occur most abundantly in Florida and may be found in small numbers along the coastal region of Massachusetts and New York, not being found in the territory between these two localities. Specimens have been examined from the following lo- calities: Florida:

Head slightly flattened between the eyes. Prothorax about one-eighth wider than long; ocular lobes moderately developed; sides sometimes broadly and evenly curved, in other cases nearly parallel along median portion and rather suddenly curved inward at base and apex; median sinuation of sides not always evident as mentioned in the original description; scales of disk of prothorax slightly convex; a few scattered stout setae, without the coarser punctures found in many of the other species. Hlytra only very slightly arcuate at base; setae of intervals rather prominent, distantly placed, more promi- nent and slightly clavate on declivity. Ventral surface clothed mostly with slender setae; sides of metasternum with rounded scales, and a few on the sides of the third and fourth abdominal sterna. Male with beak only slightly longer than prothorax; third abdominal sternum deeply concave at middle; all the abdominal sterna finely and moderately punctate, the seventh with a median apical area which is nearly smooth, having only a few scattered tiny punctures; tips of elytra conjointly rounded. Female with base of third ab- dominal sternum flat or slightly convex, sometimes with a small median concavity at the posterior margin; seventh sternum scarcely modified, having only a median apical area which is less densely and more finely punctate, this region being very slightly depressed; apex of seventh sternum truncate; apex of seventh tergum slightly emarginate at middle; tips of elytra very slightly separately sub- acuminate.

Notes on Types. The type of this species, a female from Put- nam county, Indiana, has been examined. The second specimen which Blatchley had before him when he described the species is a male from Vigo county, Indiana. The type is in the Blatchley collection at Purdue University.

Distribution Notes and Comments upon a Collection of Mexican Lepidoptera

Part I—Rhopalocera WM. D. FIELD,

Department of Entomology, University of Kansas

Asstrract: In this paper 189 species of butterflies are listed. Nine species are new to Mexico. Thecla istapa Reakirt is taken out of the synonymy and is used for the Mexican subspecies of Callicista columella (Fabr.). Lycaena alce Edwards is also taken from the synonymy and is used for the United States and northern Mexican subspecies of Hemiargus isola (Reakirt). The variation of a number of species is discussed. A number of the locality records are new.

URING an extensive collecting expedition in Mexico in the sum-

mer of 1938 by Mr. L. J. Lipovsky and Mr. H. D. Thomas, the former secured a fairly larger number of Lepidoptera, most of which have been deposited in the Snow Entomological Museum of the Uni- versity of Kansas. This collection, added to a collection of Rhopa- locera taken by H. D. Thomas during his trip through Mexico in the summer of 1936, contains a total of 189 species. Included in this number are nine species not before known to occur in Mexico. Al- though none of the localities were collected thoroughly for Lepidop- tera, since the expeditions were organized mainly to secure aquatic Hemiptera and other orders of insects, a great number of locality records are new.

The male from Cuautla, one of the males from Cocula and four of the males from Union de Tula have entirely black hind wings on the upper surfaces and thus represent a form of the typical subspecies that seems to be parallel in development to the form nigrescens Wright of C. lacinia crocale.

CuinvuaHuaA. Chihuahua, July 21, 1938, one male, four females. San Luts Porost. Huichihuayan, September 25, 1938, one male.

None of these specimens are of the typical form crocale Edw. The male and two of the females from Chihuahua are of the orange suffused form named rufescens Wright. The remaning two females are prob- ably also of the rufescens form, but approach typical crocale in having pure white spots on the forewings, both above and below. The male from Huichihuayan is of the form nigrescens Wright.

This subspecies is easily distinguished from typical fatima in several characters. The submarginal white band of the upper side of hind wings extends only to vein Me in venusta, whereas in typical fatima it continues to the anal angle, although it is usually only faintly indicated in inter-

spaces Cu; and Cug. In the female of venusta this band is continued below vein Ms as a series of three orange-red spots. In the female of typical fatima this band is white throughout. The red submesial band of hind wings is twice as broad in venusta and is much brighter in color. In interspace My, of hind wings, between the submesial red band and sub- marginal white band there is a round, black spot, very distinct on the under surface and at least slightly indicated on the upper surface. In the typical subspecies this spot is usually absent, but, if present, is very inconspicuous and usually lies next to the white band.

Typical columella Fabricius was described from the West Indies. It ranges from there into Florida and through the Gulf States. A compari- son of the above series of species with a series of typical columella from Miami, Fla., has led to the discovery that the Mexican specimens differ subspecifically from the Florida ones. The name istapa Reakirt, based upon specimens taken near Vera Cruz, Mexico, is available for the Mexi- can subspecies.

The main difference between istapa and columella is found in the re- duced maculation on the under surfaces of the former subspecies. This is most evident in the submarginal spot in interspace Cu, of the hind wing. In istapa the light colored lunule on the inner side of the marginal black spot is yellow (not orange as is the case in typical columella) and rather thin, being less than half as thick as the black spot which it caps. In columella the orange lunule is large, being as thick or nearly as thick as the black spot. The ground color on the under surface of the wings is lighter in istapa than in columella, being a light grey and usually with- out the distinct brownish tinge found in columella.

The name alce Edw., based upon specimens from Colorado and usually referred to as a synonym of isola is in reality a good subspecies. Typical isola, described by Reakirt from specimens taken near Vera Cruz, Mexico, is slightly larger than alce, having an average wing expanse in the male sex of 24 millimeters. The single female specimen of zsola in the series from Rio del Monte has an expanse of 27 millimeters. A series of twenty specimens of alce from Colorado, Kansas, Texas and Chihuahua was measured and found to have an average expanse of 22 millimeters in the male sex and 24 millimeters in the female sex. The most striking differ- ence between the two subspecies is in the ground color of the under sur- faces, which is dark grey in typical zsola and light brownish-grey in alce. The palpus, underside of thorax and abdomen in alce are white, in isola grey.

These specimens compared with a series from Texas and Florida before the writer are somewhat larger (in the Mexican specimens the average length of forewing is 30 mm. in the male and 33 mm. in the female, while in specimens from either Texas or Florida the forewing averages 1 mm. less in each sex) and have slightly broader black borders to both fore and hind wings in the male and to the forewings of the females. These borders are on the average about 2 mm. wider in the Mexican specimens than in the Texan or Floridan specimens. R6ber has described a sub- species under the name of centralamericana as having a very broad black margin to the hind wing. Whether these Mexican specimens represent this subspecies or not cannot be ascertained from Rober’s inadequate description.

The Forlon specimens are quite typical male marcellina, having con- siderable more markings underneath than in Phoebis sennae eubule (Linn.) (the only other subspecies found on continental North America). The specimen from Huichihuayan, however, is a dwarf and has the maculation on the under side of wings reduced to the normal spots at the end of the cells in the fore and hind wings and five small brownish dots in base of under surface of hind wing. It is thus similar to the form drya Fabr. of P. sennae eubule. The female from Aqua Fria represents the albinic form pallida Cockerell.

Chapala, Sep- tember 11, 1938, one female. CamprcHr. Hacienda Balchakaj, Rio Chumpan, September 11, 1936, two males.

This subspecies, as compared with the other subspecies of agarithe is noted by the great decrease in reddish-brown maculation on the under- surfaces. There is considerable variation in the amount of this reduction both in the above specimens and also in typotypical specimens from Florida. Three of the Forlon specimens are entirely immaculate under- neath except for the diagonal line on the forewing. Other specimens

have a few small reddish-brown spots scattered over the wing, while the rest are much more heavily marked. The maculation in this subspecies is never as heavy as in the other subspecies. One of the females from Forlon is of the albinic form albarithe Brown.

All of the above specimens, with one exception, are of the typical form, having a white ground color with a deep yellow base to the forewing and a slight suffusion of pale yellow on apex of forewing which is sometimes also found on the hind wings. A single specimen of the female form unicolor Godman & Salvin is represented in the above series. It is en- tirely yellow in color.

Two males from Cuernavaca and a single female from Acapulco are of the typical form jucunda. The remainder of the specimens belong to the form stdonia Felder in which the disc of the hind wing is greatly suffused with black from the borders which are in turn enlarged and prolonged around the wing to the anal angle and sometimes slightly along the ab- dominal margin. All of the sidonia females mentioned above are albinic and thus represent a form similiar to pallidula of typical jucunda. Eurema (Eurema) palmyra lydia (Felder).

Errata in Two Recent Papers on Taphrina A. J. MIX,

Department of Botany, University of Kansas

N TWO recent papers by the writer on the genus Taphrina (The

Genus Taphrina: I. An Annotated Bibliography, University of

Kansas Science Bulletin 24:9:113-149. II. A List of Valid Species, Ibid 9:151-176:1936) certain errors and omissions occur.

Another reference should have been included in the bibliography: Lind, J. Danish Fungi as represented in the herbarium of E. Rostrup. Copenhagen, 1913. Lists the species of Taphrina known in Denmark.

In the species list, an additional host, Polystichum acrostichoides (Michx.) Schott, should have been given for Taphrina filicina Rostr. This is an omission only because these papers are compilations from the literature and present no new information concerning species of Taphrina. Actually the fungus on Christmas fern is not Taphrina filicina, but Taphrina Polystichi Mix.* Another host, Prunus nigra Ait., should be added for 7. communis (Sadeb.) Giesenhag.

Certain undescribed species mentioned in the bibliography are not included in the species list. Three species: Taphrina Blechni on Blechnum sp., T. Selaginellae on Selaginella Menzies, and T. Fagi on Fagus sp., are not mentioned in either paper. The only reference to these fungi that has been found is their mention (without author- citations) by Laubert in the latest edition of Sorauer’s Handbuch der Pflanzenkrankheiten. Presumably the names and descriptions are to be found with herbarium specimens accessible to Laubert.

Number 30 in the species list, “Taphrina alni-incanae (Kihn) Magn.” should by strict adherence to the principle of priority be called Taphrina amentorum (Sadeb.) Rostr.

Morphological Differences in Taphrina Caerulescens

_Upon Different Species of Quercus EDNA OLD THOMPSON,

Department of Botany, University of Kansas

Apsrracr: The range of size of the asci of Taphrina caerulescens (Desm.) Tul. should be extended from 40-80y, x 15-25y, as given in the literature to 30-120y, 11-84y, as shown by a study of a large number of infected host species.

The form of the asci of 7. caerulescens varies upon different hosts, as does also their manner of insertion between the epidermal cells. The bases of many of the asci show well-developed rhizoidal appendages while upon others the bases are blunt or merely tapered.

Taphrina rubrobrunnea (Pk.) Sace. is similar in its morphology to Taphrina caerulescens (Desm.) Tul. and is therefore referred to that species.

Since Taphrina Kruchii (Vuill.) Sace. is reported to produce witches’ brooms and geotropic curvature of the twigs of its host, it should be retained as a separate species, although its asci are similar in form to those of 7’. caerulescens.

Some evidences of biological specialization of Taphrina caerulescens lave been- observed. Further investigation of such specialization by means of cross- inoculation experiments is desirable.

REVIOUS studies of Taphrina caerulescens (Desm.) Tul. have

been concerned with the effects of the fungus on the host, the dimensions of the asci and spores and, to some extent, with the shape of the asci and their manner of insertion in the host tissue. Little attention has been given to differences in the morphology of the asci on differént host species.

Ascomyces caerulescens Desm. and Mont. was described by Desmaziéres (1) as having no mycelium, the “sporangium”’ consti- tuting the entire fungus. Sporangia (asci) were cylindrical, obtuse at the apex, 1/20 mm. (50y.) long and 1/60 mm. (16.6y.) thick. This new genus Ascomyces was not clearly distinguished from the existing

(357)

358 Tue UNIversity SCIENCE BULLETIN

genus Taphrina, and A. caerulescens was therefore renamed Ta- phrina caerulescens by Tulasne (15).

Ascomyces alutaceus Thm. was described by von Thiimen (14) from the leaves of Quercus pubescens Willd., as having broadly cylindrical or nearly oblong asci, narrowed at the base, obtusely truncate at the top, 28-36 mm. long and 20 mm. broad. (Presum- ably microns were meant rather than millimeters.) Saccardo (11) emended the description of A. alutaceus from the leaves of Quercus robur L., giving as measurements for the asci: length, 35-40y; breadth, 20u. This fungus was reduced to synonymy by Giesen- hagen (3), becoming Taphrina caerulescens (Desm. and Mont.) Tul.

Taphrina caerulescens was again described from leaves of Quercus pubescens Willd. by Sadebeck (12). His measurements for the asci were: 55-70u < 15-20u.. Sadebeck observed that the asci sometimes penetrated between epidermal cells as much as 25y. if the bases of the asci were much narrowed, or only about 10» if the bases were relatively blunt.

The measurements given by Peck (8) for the asci of Ascomyces extensus Pk. on leaves of Quercus macrocarpa Michx. were: .002- 0025 in. (50-62.5y.) long, .0009-.0011 in. (22.5-27.5u.) broad. This fungus was referred to Taphrina caerulescens by Farlow (2).

Peck (9) also described as new, Ascomyces rubrobrunneus Pk. from the leaves of Quercus rubra L. The asci were oblong, truncate at the apex, .002-.003 in. (50-75y.) long by .0006-.0009 in. (15-22.5y.) broad. Peck distinguished this fungus from Ascomyces alutaceus Thm. by the color of the spots, larger asci and different shape of the spores, and it has never been reduced to synonymy.

Kruch (6) reported a new species of Taphrina which caused witches’ brooms, swelling and geotropic curvature of twigs, of Quercus Ilex L. This fungus was described as Exoascus Kruchu by Vuillemin (17), who found that it differed from Taphrina caerules- cens in the dimensions of the asci and in that the hymenium covered the whole lower surface of the leaf. According to Vuillemin, the asci of H. kruchii are 72-80y. long, 21-23y broad, and have a footlike base inserted beneath the cuticle. The protruding portion is nar- rowed into a neck at the point of emergence and the ascus is swollen slightly at the tip. Sadebeck (13) and Giesenhagen (3) reported the measurements of the asci of Taphrina Kruchii (Vuill.) Sace. as 65-75u. * 15-20u, broadened at the base to 30-40. Sadebeck also observed “haustorium-like projections” into the tissue.

Patterson (7) had available for her studies specimens of Taphrina

caerulescens on Quercus velutina Lam., Q. rubra L., Q. alba L., Q. coccinea Muench., Q. phellos L., Q. Douglasti Hook. and Arn., Q. nigra L. and Q. laurifolia Michx. She found the asci often am- phigenous, rounded at the apex, 40-80¥ 15-25y. One or more processes extended in between the epidermal cells for 10-20y, the longer processes were two or three to an ascus, the shorter and blunt processes one to an ascus. Presumably this description was made from a study of the fungus on a number of the hosts men- tioned above. Patterson’s figure of 7. caerulescens as occurring on Quercus phellos L. shows asci with bases somewhat tapered and projecting between the epidermal cells.

Giesenhagen (3) illustrated an ascus of Taphrina caerulescens with a tapered base, and gave measurements of the asci as 55-70y. 18-24...

Jaczewski (4) distinguished a variety of J. caerulescens on Quercus coccifera L. The asci of this fungus, T’aphrina caerulescens var. Quercus-cocciferae lacked rhizoids, and were seated on the epidermis.

Jankowska (5) found asei of T. caerulescens on various hosts to be of two types: (1) clavate asci, gradually narrowed to a point at the base and inserted, and (2) cylindrical asci, sessile by a broad base. Jankowska reported the size of asci as 55-80u * 18-24u.

The studies! to be reported here are concerned with the morphol- ogy of the asci of Taphrina caerulescens on thirty-six different species of Quercus. The list of host species is undoubtedly not com- plete, but it is sufficiently long to indicate the variability of the fungus from host to host. The nomenclature followed for the American oaks is that of Trelease (16) and for foreign oaks of Rehder (10) or of Index Kewensis.

In table 1 is presented a compilation of the measurements of the ascl of T. caerulescens on the different species of oaks studied.

From this table it may be seen that the asci of Taphrina caerules- cens on the different species of oaks vary in size from 30y to 120y. in length, and from 11p to 34y in width. The largest asci were found on Quercus geminata, 2. coccinea and Q. Douglasii, and some of the smallest on Q. Cerris, Q. macrocarpa, and Q. undulata.

In addition to differences in size, much variation occurs in the form of the asci on the different species of oaks. In general, they

are cylindrical or club-shaped and somewhat flattened at the apex. Frequently they are slightly constricted at the point of emergence from the host tissue. The bases of the asci may be seated on the epidermal cells of the host or somewhat inserted between them. Commonly the bases of the asci are gradually tapered and thus wedged closely between adjacent cells of the host epidermis (Plate XXXIX, Q. geminata through Q. fruticosa). The asci formed on Quercus Kelloggii or on Q. alba are blunt or slightly rounded at the base. On certain hosts the asci have deeply inserted projections

Tuompson: MorrpHo.uocicaAL DirreERENCES 361

which may clasp the epidermal cells of the host. The asci on Q. borealis and on Q. Cerris very frequently show such rhizoidal elon- gations (Plate XX XIX).

The asci formed upon any one host species are rather constant in size and shape. This became especially evident in those cases (Q. maxima, Q. velutina) in which study was made of several specimens collected at different times and in different places. They may, how- ever, be variable with regard to the form of the base and its manner of insertion.

In Plates XXXVIII and XXXIX an attempt has been made to show differences in both size and morphology for all forms studied. In these figures each ascus has been drawn median size, as expressed by the measurements in Table I. In addition bases of asci have been shown for each form, representing every type of ascus base seen on each host species.

With respect to the form of the base and the manner of insertion in the host tissue, it is possible to recognize two host groups. The following oaks usually show asci with one or more rhizoidal projec- tions: Quercus acutissima, Q. borealis, Q. Cerris, Q. coccifera, Q. coccinea, &. ellipsoidalis, Q. georgiana, Q. ilicifolia, Q. imbricaria, (). lanuginosa, Q. macrocarpa, Q. marilandica, Q. maxima, Q. Mir- becku, Q. mgra, Q. palustris, and. Q. velutina. The occurrence of rhizoids in the fungus on ®. coccifera seems to invalidate the descrip- tion by Jaczewski (4) of a variety on this host.

The host species upon which the asci are usually flattened, or merely tapered for close insertion between the epidermal cells are: Quercus alba, Q. cinerea, Q. fruticosa, Q. geminata, Q. dentata, Q. Kelloggit, Q. laurifolia, Q. phellos, ®. robur, Q. sessiliflora Q. stellata, QM. undulata, and Q. virginiana.

When, however, size-differences in the asci are taken into account as well as the type of ascus base, it is no longer possible to divide the forms studied into two well-defined groups. In fact if an attempt were made to divide Taphrina caerulescens into subspecies or varie- ties on the basis of ascus morphology, a separate category would need to be made for nearly every host species.

At present, little can be reported concerning the extent of biologi- cal specialization among forms of Taphrina caerulescens. That such specialization may exist is evidenced by the following observations: A. J.

Thompson? has frequently seen, in the vicinity of Amherst, Mass., badly infected trees of Q. maxima growing near uninfected trees of @. alba. Specimens were received in 1938, from Dr. E. A. Bessey with note enclosed calling attention to scant infection of Q. coccinea and abundant infection of Q. borealis Michx. in the same locality (Huron county, Michigan). Dr. H. N. Hansen has observed® that in a garden at Saratoga, Cal., a tree of Q. Kelloggw bore numerous infections, while a tree of Q. lobata with intermingling branches showed none, and a tree of Q. agrifolia growing about twenty-five feet away was also free of infection. That these species are sus- ceptible to forms of the fungus in other localities is apparent from the numerous infected specimens received.

H. H. Wedgworth (18) reported that in Mississippi in 1926 Taphrina caerulescens attacked nearly all species of oaks, being most severe on Quercus nigra L. and Q. rubra L., while Q. phellos L. showed marked resistance.

Since Taphrina caerulescens does not occur in the vicinity of Lawrence, Kan., the nearest known station being fifteen miles dis- tant, oaks growing out of doors at Lawrence can be inoculated with- out danger of infection from natural sources. Accordingly, in early spring, 1937, several trees of three species: Q. macrocarpa, Q. palus- tris, and Q. Muhlenbergu were inoculated with cultures of JT. caeru- lescens from the following hosts: Quercus marilandica, Q. maxima, Q. virginiana, Q. velutina, Q. laurifolia, Q. Kelloggu. No infection resulted, presumably because no rain ensued until after the leaves were out and well grown. Further cross-inoculation experiments would be very desirable.

In addition to the forms recognized as belonging to Taphrina caerulescens, two other fungi which have been considered to be separate species have been studied: Taphrina rubrobrunnea (Pk.) Sace. and JT. Kruchiwi (Vuill.) Sacec. Type material of T. rubro- brunnea upon Quercus maxima Ashe was examined. The asci were found to agree closely in size and shape with those of Taphrina caerulescens upon the same host. Obviously this species is synony- mous with, and is here referred to Taphrina caerulescens (Desm.) Tul.

Examination of a leaf fragment of Quercus Ilex L. infected with Taphrina Kruchii, showed the whole lower surface covered with asci.

2. Reported in personal conversation with the writer.

3. Reported in a letter from Dr. H. Earl Thomas. In personal conversation Doctor Hansen expressed the opinion that leaves of Q. agrifolia (an evergreen oak) may not have been susceptible at the time leaves of Q. Kelloggii became infected.

Tuompson: MorrHouocicAL DIrrERENCES 363

In size and shape the asci were similar to those of 7. caerulescens. However, 7’. Kruchii should, for the present, at least, be retained as a separate species since, according to Kruch (6), it produces witches’ brooms, deformation and geotrophic curvature of the twigs of its host.

The morphology of the ascus, including size, shape, and presence or absence of a stalk cell, has always been the basis of species- differentiation within the genus Taphrina. It would be perfectly possible to divide Taphrina caerulescens into a number of new species on ascus size and shape. For example, the fungus on Quercus borealis and that on Q. Kelloggi are widely different, and the treat- ment of them as separate species would be quite in line with the procedure of various mycologists in describing different species of Taphrina on different species of such host genera as Betula and Prunus. The first of these “new species” might easily include also the fungi on Quercus Cerris and Q. macrocarpa. If, however, the forms on Q. lanuginosa and Q. ilicifolia were added a good begin- ning would have been made toward including all or nearly all of the forms here illustrated in one species, which, of course, would be 7. caerulescens. The alternative would be to erect a new species for each new host species. Such a procedure is, of course, undesirable, in fact any subdivision of the existing species should not be at- tempted until more is known of the biological peculiarities of Ta- phrina caerulescens on different species of oaks. The differences in morphology that have been observed point, however, to the great desirability of learning more about these biological relationships.

Taphrina caerulescens then, may be said to include those forms of Taphrina which affect the leaves only (not attacking twigs or caus- ing witches’ brooms) of many species of Quercus, producing definite spots or blisters, or occasionally deforming the entire leaf. The asci may be produced on either or both sides of the leaf. They may be cylindrical or club-shaped and vary in length from 30-120. and in diameter from 11-34. Their means of insertion between the epidermal cells varies from a blunt, seated or slightly inserted base to deeply inserted bases with well-developed rhizoidal appendages. These appendages in some cases grow partially around the epidermal cells and so are firmly anchored to them. The ascospores are rarely seen, but the asci are filled with numerous small conidia.

A New Synaptomys from the Pleistocene CLAUDE W. HIBBARD,

Kansas University, Museum of Vertebrate Paleontology, Lawrence, Kan.

Apstract: A new lemming, Synaptomys bunker, is described from the Pleistocene. The associated vertebrate fauna includes Archidiskodon imperator (Leidy), fragments of a small duck and fish. A list of associated invertebrate species is given.

INTRODUCTION

URING the summer of 1937, while collecting on the XI Ranch

in Meade county, Kansas, we secured a few vertebrate remains from a Pleistocene deposit. Among them is an apparently new Synaptomys. The geology of this section is being studied by Dr. H. T. U. Smith and will appear at an early date. For the new lem- ming I wish to propose the name:

Synaptomys bunker sp. nov.

Holotype. No. 4610, Kansas University Museum of Vertebrate Paleontology; right lower jaw, bearing M, and M,. Collected by the Museum Field Party, July, 1937.

Horizon and type locality. Pleistocene, K. U. M. V. P. Locality No. 5, twenty-one miles south of Meade, Kan.

Diagnosis. Belongs to the subgenus Synaptomys; M,, anterior loop with broadly confluent pair of triangles, with greatly reduced outer anterior salient angle; anterior enamel border of the second outer salient angle in line with the posterior enamel border of the third inner salient angle; M,, with well developed second alternat- ing triangle; larger than Synaptomys cooperi gossi.

Description of type. Teeth rootless; cement present in reéntrant folds; incisor passes completely lingual to molar series, but broken so

368 THE UNIVERSITY ScIENCE BULLETIN

that the posterior termination is unknown; mental foramen normal in position but slightly larger than that of Synaptomys coopert gossv; pit present between M, and coronoid process; two large foramina opposite outer border of M,. M, consists of three outer and three inner salient angles, a posterior loop, three alternating closed tri- angles, the first and third are internal, the anterior loop is formed by a broadly confluent pair of triangles which greatly reduce the outer anterior salient angle. The apex of the second outer salient angle is nearly opposite the apex of the third inner salient angle, so that the anterior enamel border of the second outer salient angle is in line with the posterior enamel border of the third inner salient angle. While in Synaptomys coopert the apex of the second outer salient angle meets the posterior enamel border of the third inner salient angle nearly at midpoint instead of nearly opposite its apex. Thus the anterior enamel border of the second outer salient angle of S. cooper? is not in line with the posterior enamel border of the third inner salient angle as in Synaptomys bunkert. The second alternat- ing closed triangle is truncated. M., with two outer and two inner salient angles, posterior transverse loop and three alternating closed triangles; the second alternating triangle well developed; apex of the second outer salient angle opposite the apex of the second inner salient angle. Anteroposterior diameter of M,, 2.8mm., antero- posterior diameter of M,, 2.2mm. The dentition of Synaptomys bunkeri is heavier than that of S. coopert. The lower teeth having a slightly greater anteroposterior and transverse diameter, also the entire jaw is slightly larger and more heavily built.

Remarks. Synaptomys bunkeri is distinguished from the fossil form, Synaptomys australis Simpson, by its smaller size. Syn- aptomys annexus (Peterson) and Synaptomys vetus Wilson belong to the subgenus Mictomys and therefore need no comparison. In size the new form corresponds rather closely to Synaptomys coopert gossi (Coues) ; it is distinguished by a heavier dentition and by the pattern of M,. A series of dentition patterns of Synaptomys c. gossi are figured showing the range of variation in the recent form studied. I am indebted to Mr. Gerrit 8. Miller, Jr., of the United States National Museum for the loan of specimens and permission to figure them. Figures 2 and 3 represent the extreme end of variation in a series of over 150 individuals of Synaptomys c. gossi studied which are nearest to Synaptomys bunkeri in pattern. These were the only two found representing any approach to the fossil form. The figures are arranged in a series to show the entire variation in dentition

Hissparp: A New SyNAPromMys 369

pattern encountered while studying the recent form. The series does not represent a true variation due to wear; for if it is noted, it will be seen that the series represents all ages and sexes arranged in any order to show the extremes of dentition pattern. Figures 6, 7 and 8 represent over ninety percent of the dentition patterns observed in adult specimens.

This species is named for Mr. C. D. Bunker, Curator of Birds and Mammals, who made possible a combined field trip with the Mu- seum of Vertebrate Paleontology during the summer of 1936, at which time were located the Meade county fossil deposits.

Associated fauna. The vertebrate remains were taken from a zone of clay in which occurred an abundance of invertebrates. I am indebted to Dr. Frank C. Baker for the identification of the in- vertebrates, with the exception of the Physa, which were identified by Dr. W. J. Clench. The associated invertebrates are as follows: Succinea grosvenort Lea, common; Stagnicola caperata (Say), rare; Gyraulus altissimus (Baker), common; Physa anatina Lea, very abundant; Physa hawnw Lea, very abundant; Helisoma trivolvis lentum (Say), very abundant.

Doctor Baker makes the following comment on the deposit, “It is predominantly a fresh water one, the few land shells have been washed in by rain (or otherwise). All the freshwater species are pulmonates, no water breathers being present. This would indicate that the body of water was not very deep. It might have been a sluggish river.”

In the deposit was found fragmentary fish material; the distal end of an ulna (No. 4612 K. U. M. V. P.) belonging to a small-sized duck (identified by Dr. A. Wetmore) and two associated upper molars (No. 46386 K. U. M. V. P.) of Archidiskodon imperator (Leidy).

A New Pycnodont Fish from the Upper Cretaceous of Russell County, Kansas

CLAUDE W. HIBBARD,

Kansas University, Museum of Vertebrate Paleontology, Lawrence, Kan.

ABSTRACT.

A new Pyenodont fish, Coelodus streckert sp. nov. is described from the Upper Cretaceous of Kansas. The type is based on a nearly complete prevomer with teeth.

R. H. D. O'BRIEN, of Russell, Kan., recently sent to the

museum for identification, a nearly complete prevomer of a Pycnodont fish collected by Mr. Ernest Strecker, of Paradise, Kan. Mr. Strecker has kindly donated the specimen to the museum since it represents apparently an undescribed species of the genus Coelo- dus. This is the first remains of a Pyenodont fish to be found in the Upper Cretaceous of Kansas.

Coelodus streckeri sp. nov. (Plate XLI, figs. 1 and 2)

Holotype. No. 946F, Kansas University, Museum of Vertebrate Paleontology. Prevomer plate nearly complete. Collected by Ernest Strecker, July 1, 1938.

Horizon and type locality. Carlile Shale, Upper Cretaceous, two and one-half miles south and one-half mile east of Paradise, Russell county (locality No. 3), Kansas.

Diagnosis. Size, large, median teeth elipsoid, posterior surface not concave.

Description of type. Prevomer larger than that of Coelodus gyrodoides Egerton. Five longitudinal rows of acrodont teeth. The internal lateral rows longer than the median row. Greatest width of dentitional series 44.9mm. The anterior portion of the prevomer

inissing. The left outer row of lateral teeth are 8 in number, measur- ing 55.2 mm., while those of the right side are 7 in number in both rows measuring 46 mm. and 51 mm., respectively. The teeth of the lateral rows are rounded in shape in the posterior part of the row, gradually becoming elipsoid as one passes anteriorly. The last two teeth in the anterior portion of the lateral rows are quadrangular in outline. The posterior border of all of the lateral teeth are con- vex. The teeth of the lateral rows have shallow apical depressions which are not wrinkled. The teeth of the median row are elipsoid, with shallow apical depression transversely placed with a tendency for a ridge to be developed along posterior border of apical depres- sion. Crowns not wrinkled. The length of the median row of teeth is approximately 52mm. The measurements of the teeth of the median row are taken from the posterior to the anterior; (first posterior tooth missing) second tooth, transverse width 12.4 mm., anteroposterior diameter 6.7 mm.; third tooth, transverse width 12.8 mm., anteroposterior diameter 6.7 mm.; fourth tooth, transverse width 11.5 mm., anteroposterior diameter 6.8 mm.; fifth tooth, trans- verse width 10.7 mm., anteroposterior diameter 6.2 mm.; sixth tooth, transverse width 9.5 mm., anteroposterior diameter 6.0 mm.; seventh tooth, transverse width 8.7 mm., anteroposterior diameter 5.7 mm.

The oral surface of the fused prevomer looking across the crowns of the teeth is strongly convex. On the superior side of the prevomer is a heavily developed median ridge. At the posterior end of the prevomer is a deep concavity.

The genus Coelodus has heretotore been known only from the Lower Cretaceous of Kansas, Oklahoma, and Texas in North Amer- ica. The species known from Kansas is Coelodus stantoni Williston from the Kiowa shales, near Belvidere, Kiowa county, Kansas.

This species is named for Mr. Ernest Strecker, who collected and donated the specimen to the Museum of Vertebrate Paleontology.

The Dermestid Method of Cleaning Skeletons OTTO W. TIEMEIER, Museum of Birds and Mammals, University of Kansas, Lawrence, Kansas

Arstrract: The dermestid beetle method of cleaning skeletons and skulls has been used in the University of Kansas Museum of Birds and Mammals for a number of years. Discussions of the procedure, the requisites of a bug room, the advantages of the method, and suggestions as to the successful utilization of the beetles are given.

OR a number of years the University of Kansas Museum of Birds

and Mammals has been using dermestid beetles very successfully in cleaning skeletons. The use of these beetles for this purpose was begun in this institution over twenty years ago. At that time the black carpet beetle Attagenus piceus, a dermestid, was such a mu- seum pest that a student, Dix Teachenor, working on small bird skulls, attempted to protect his specimens by enclosing them in tin ‘ans. Later Mr. C. D. Bunker, in charge of the University of Kan- sas Museum of Birds and Mammals, upon opening the beetle-proot containers, found these delicate skulls cleaned and completely intact, and the compartment quite active with dermestids. The skulls which had been so painstakingly enclosed had, unknown to Mr. Teachenor, already been infested with dermestid eggs.

For some time these small dermestids were used by Mr. Bunker for skeleton cleaning, which was done in a specially constructed bug room.

The custom of hanging carcasses out to dry led to the use of the larger dermestid Dermestes vulpinus, herein referred to as “bugs,” which, enclosed in similar containers, did the work much more quickly.

The University of Kansas Museum is, however, still using the small black carpet beetle for skeletal cleaning which the larger

378 THe University ScrENCE BULLETIN beetles refuse or fail to accomplish, for although they are much slower, they will eventually clean nearly any specimen

The University of Kansas Museum has had numerous requests for colonies of the larger beetles and for information as to how they should be used. Hall and Russell (1933) have described the teeh- nique used at the Museum of Vertebrate Zodlogy, University of California. The methods have been improved and greatly simplified since that time.

It is a very simple matter to acquire a colony of dermestids. Anyone who has ever disturbed an animal carcass has seen these brownish-grey beetles with their floury abdomens and the prickly brown larvae scurrying out of the light. They can be found in large numbers under any old carcass that may be seen out in the open, or from a carcass that has been hung out to dry for several days.

The room in which these bugs are housed need not be very elabo- rate, but there are a number of requisites to be kept in mind when it is built. The beetles will migrate during the spring months and the collections of skins of the museum should be in a separate build- ing. The size depends upon the number of specimens that it is in- tended to hold. At the University of Kansas Museum we have a room about fifteen by thirty feet. The room should be insect proof as nearly as possible. The walls, floor, and ceiling should be plas- tered smoothly so that spiders and cockroaches can be kept at a minimum.

In our bug room the windows are small and sereened with fine copper mesh. They are tightly sealed during the winter, but may be opened in the summer to regulate the temperature when the pre- parator is working in the room.

Shelving can be of anything, but preferably of soft pine or steel. If constructed of soft pine, it will have to be replaced every five or six years because the larvae will bore their way into the wood to pupate and weaken the structure. The room should be absolutely dark at all times, as the beetles will not do their best in the lght. The temperature need not be kept absolutely constant. In the winter, we have several steam pipes that furnish the heat. All that is necessary is to keep the room warm.

We have found that a hail-screen cage on a steel-top table is a very useful receptacle for specimens when they are first brought in from the drying line. The purpose of the hail-screen cage is to keep out cockroaches and animals such as mice which sometimes get into the bug room in spite of all precautions.

TIEMEIER: CLEANING SKELETONS 379

The animals that are to be cleaned should be drawn and all the feathers, hair, and skin removed. It is a good practice to remove the tough calluses from the feet in the larger birds because the bugs will seldom be able to clean them up after the cartilage and skin has hardened. Special care should be taken to remove the primaries and other feathers from the tips of the wings.

Material which is left uncleaned by the bugs will have to be sub- jected to a tedious process of boiling and scraping, which in the case of small specimens is almost certain to destroy delicate struc- tures.

In warm weather it is necessary to do some defleshing. Large specimens should have most of the muscular and fatty tissue re- moved from the fleshy parts of the body.

It is well to disarticulate large specimens before they are hung up to dry so that they will not be bulky and hard to handle. The tongue and hyoid apparatus of large mammals should be removed and the hyoid apparatus dried separately. All skeletal material should be prepared so that air can circulate freely about it. Slits should be made between the ribs of large animals. Fles deposit eggs in small pockets that are not exposed to the air and specimens that have been infested with maggots are not cleaned up so well by the bugs.

After the animals have been drawn and prepared for skeletoniza- tion they should be hung up some place in the open where they can dry rather rapidly. In the ease of the larger birds, it is advisable to tie the wings against the body and then with a half hitch of the same cord around the neck hang the carcass out to dry.

When the carcasses are dried so that a hard coat is formed over the flesh, they are brought into the bug room and placed inside the cage on the steel table.

Within a few days after the carcasses have been placed in the bug room they are ready to be put away in boxes. The eggs that have been laid on the carcass after it was placed in the bug room and those that had been laid on it while drying will have been hatched and the resulting larvae will begin to eat the flesh. When- ever the small particles of bug droppings appear on the carcass it is ready to be put into boxes.

These are double boxes made of corrugated straw board just large enough to contain the carcass. There are several advantages of the corrugated boxes over steel or wooden boxes. The small cor- rugations serve as places for the larvae to pupate so that the entire life history of the beetle take place within the same container

880 THE UNIVERSITY SCIENCE BULLETIN

The boxes are cheap and ean be replaced every few years. They are tight-fitting and thus help to control spiders, and they are sub- stantial enough to be stacked.

If the skeletons are small ones they need not remain in boxes very long. A mouse or small bird will be cleaned in one or two days. Large skeletons will require a corresponding length of time. Un- less we are in immediate need of the skeletons we leave them all until fall.

In the late fall the final cleaning begins. By that time the weather is cool enough so that the preparator is not annoyed by “bug dust,” which is composed of the spiny larval bristles. The combination of minute spines and the preparator’s perspiration produces very unpleasant effects.

The contents of each box are emptied upon a large square of black paper. With a pair of forceps, when necessary, the worker sorts over the material, picking out the bones which are then dusted and placed in specimen boxes.

The presence of fat often creates a definite problem. Long bones may contain considerable fat. If much of it is present in any place it will be spread over the entire skeleton by the bugs. Such skeletons as those of hawks and ducks will often come out covered with grease. It is a good procedure to remove as much fat as possible from the carcass to prevent its occurrence on the bones.

A twenty-eight percent solution of ammonia water serves as an adequate and efficient method of degreasing the skeletons. Im- merse the bones and leave them for twenty-four hours. Remove the bones and place them in water for another day and then place them in the sun until they are thoroughly dry. The sun will bleach the bones shghtly during the drying.

If skeletons of large mammals are desired for mounting purposes it is suggested that small holes be bored in each end of the long bones and the fatty contents be forced out with the aid of steam and air pressure.

Skull cleaning is a problem in itself. Mr. A. E. Borell (1988) sug- gests the use of small metal containers into which the skull is placed with a number of larvae. It is during the larval stage that the bugs do their most rapid and effective work. However, if there is no immediate need for the skull it may be left on the skeleton and will in time be cleaned up by the bugs. For best results the skulls should be put in the bug room as soon as they are obtained except that the larger ones will have to be dried enough so that they will not become covered with mildew.

TIEMEIER: CLEANING SKELETONS 38]

The dermestid method has many advantages over the maceration method or boiling. The ease with which cleaning is accomplished is a great advantage. The only limit to the number that can be cleaned is the number that can be obtained. One preparator doing part- time work can clean thousands of skeletons in one year’s time.

But even more important for research is the fact that the skele- tons come out intact with sutures in place and soft bones undis- solved. No lgaments are weakened to the extent of losing minute bones. Hyoid apparatus, zygomatics, lacrymals, auditory bullae, phalanges, and other elements are certain to be retained.

A striking example of the efficiency of the dermestid method is presented by a small ring-neck snake. It would be nearly impossible to clean such a specimen with its scores of tiny curbed ribs and its minute vertebrae. But a few hours in the bug room will provide a perfect skeleton, clean and white as a pearl, with every tiny rib firmly in its own place.

While a few preparators have stated that they attributed the loss of certain small bones to the workings of the bugs, we have never found it to be true in this museum. It was only by dermestid method that I was able to discover the wide prevalence of the os opticus of the bird’s eye.

In other methods of preparing skeletons large animals present ereat difficulty in the cleaning problem, but in the dermestid method size is no handicap. It is Just as easy to clean a moose as it is to clean a mouse.

If the bug room contains large and active colonies of dermestids, skeletons such as those of small birds, bats, and mice need not be hung out to dry before being put in the bug room. Forty-eight hours after they have been placed in the hail-screen cage they will be stripped clean.

There are probably a number of reasons why the dermestid method has been so successful in the University of Kansas Museum. The prime requisite for the dermestid method is, of course, a large supply of bugs. And to have a large and constant supply of bugs there must be an adequate food supply. If necessary, carcasses of common animals must be put in the bug room to feed the beetles. At the present time the bug room in the University of Kansas Mu- seum Is literally alive with bugs, and the peculiar noise of their ac- tivity is never hushed.

Flesh should not be removed from small skeletons and skulls, as

there must be sufficient food material for the bugs to become es- tablished.

382 THE UNIVERSITY SCIENCE BULLETIN

We have found that papier-maché bricks are the most successful provision for pupation of bugs not in individual boxes. These bricks may be placed around about the room, on the floor, in the cages, or on the shelving.

The worst pests of the bug room are the spiders and cockroaches. We take as many precautions as possible to prevent these pests from getting into the bug room. [In spite of all our efforts, however, they do manage to get in. Because of this we have found it expedient to clean the bug room every few years, destroying all old boxes and fumigating thoroughly with sulfur. In a few months, as I have al- ready suggested, we will again have a large working colony.

The final requisite for good bug work is absolute darkness. They are naturally found either under a carcass or excavating beneath the dried surface. This should be kept in mind in order to obtain clean skeletons.

I wish to acknowledge my indebtedness to Mr. C. D. Bunker, of the University of Kansas Museum of Birds and Mammals, under whose direction and supervision this method of cleaning skeletons has been developed.

New Species of Mexican Anura EDWARD H. TAYLOR, Department of Zodlogy, University of Kansas

Apstract: Five species of Mexican tailless amphibia are described as new from the Edward H. Taylor-H. M. Smith collection: Hyla hazelae, type locality, Cerro San Felipe, Oaxaca, Oaxaca; Hyla robustofemora, Cerro San Felipe, Oaxaca, Oaxaca; Hyla robertsorum, El Chico National Park, southern Hidalgo; Syrrhophus latodactylus, Huasteca Cafion, 15 km. west of Monterrey, Nuevo Leon; Hleutherodactylus vocalis, El Sabino, Uruapan, Michoacan.

HILE collecting at night on the Cerro San Felipe, a mountain which rises just to the north of the city of Oaxaca, I obtained two specimens of a small species of Hyla from brush and weeds growing along a small stream, fed by a spring, at an elevation esti- mated to be about 2,700 meters. The frogs were calling from heights of from four to ten feet above the ground. Numerous specimens were heard.

Fic. 1. Hyla hazelae sp. nov. Type. EHT-HMS, No. 16263; Cerro San Felipe, Oaxaca, Oaxaca. Actual snout to vent measurement, 35 mm.

Description of the type. Head very shghtly wider than long, the canthus distinct, somewhat rounded; vomerine teeth in two raised, slightly diagonal groups lying completely between the choanae, and not or scarcely reaching their upper level; the groups are trans- versely oval, separated from each other and the choanae by an equal distance; openings of the mucous glands in the roof of mouth form- ing a straight line which is closer to the vomerine teeth than to anterior part of mouth; tongue generally oval, very slightly emar- ginate behind, free for about one-sixth of its length only, more than

Taytor: New Mexican ANURA 387 half the width of head; openings of the vocal sacs very much elongated (5.5mm.); distance between choanae, 3.5 mm.; diameter of choanae, 9 mm.

Nostrils pierced near the extreme tip of snout at its upper edge, but the snout slopes forward to lip, the profile in outline is curved; loreal region somewhat concave, sloping very obliquely to lip; eye- lid very distinctly narrower than the interorbital distance (3.15 to 4.2 mm.); diameter of eye about equal to its distance from nostril;

tympanum distinct, small (1.6 mm.), overhung by a very heavy, thickened, somewhat angular fold which passes from eye to near insertion of arm, and conceals the upper part of the tympanum; the areas about nostrils somewhat swollen with a slight depression be- tween them.

When limbs are folded at right angles to the body the heels over- lap about two millimeters; the tibiotarsal articulation reaches to very near the anterior edge of the eye; a skinfold across the breast; anal flap lengthened and narrowed with a strong median groove; the anal opening is at about the level of the ventral surface of the femur.

388 THE UNIVERSITY SCIENCE BULLETIN

Hand about one-fourth webbed, the webs continued as rather wide margins on the digits to the digital pads; width of the latter distinctly larger than pads on toes; subarticular tubercle of outer finger divided* those on other fingers single, the proximal tubercles of the third and fourth digits are small; a very large, flattened en- largement at base of first finger which bears a patch of dull brown, horny spicules (in paratype these are continued a little onto the edge of the first finger); below the enlargement is an elongated palmar tubercle; outer palmar tubercle bifid (somewhat trifid on right hand); a few distinct supernumerary tubercles; entire under surface of hand with irregular, often indefinite, areolate granules; on under surface of forearm a regular series of rounded tubercles extend from wrist to elbow (these are very distinct, being white or silver-cream on a dark blackish background) ; feet a little more than half webbed, the webs extended as a fringe to the pads; subarticular tubercles of the third and fourth fingers smallest; a rather large inner meta- tarsal tubercle, and a small outer one, scarcely distinguishable from the supernumerary tubercles of the sole; a strongly defined tarsal fold to heel.

Skin above appearing rather smooth but actually under the lens it is finely corrugated; sides somewhat wrinkled and granular, the eranules indistinct; chin and breast irregularly granular and folded; ventral surface of abdomen and most of under surface of femur evenly areolate, the granules subequal; below anal opening is a row of strongly enlarged salient tubercles.

Color in life. Dorsal surfaces of body and limbs deep leaf green, the ventral surfaces bright lemon yellow. Eyes dark; an ash to gray-lavender line from snout through eye; rows of silver-cream dots under forearm and a similar series on the posterior edge of foot and heel; a silver line above the anus bordered below by black; the large tubercles below anus tipped with silver cream; under sur- face of hands and feet with considerable pigment; a few minute cream flecks on dorsal surface. Thighs and shanks olive flesh; sides indefinite dark and gray.

Variation. The paratype when caught was a much lighter yellow- ish-green above, and the posterior parts of thigh were flesh color.

In alcohol there is no trace of the line from snout through eye. The paratype has less pigment under palms and soles. In the pre- served specimens there is a lighter area indicated under the eye which I failed to observe in the living specimens.

Remarks. The species is related to Hyla bistincta, which occurs on the same mountain. It differs from that species in the reduced size of the nuptual callosities on the first finger and the absence of asperities on the second finger. The presence of the very large sub- anal tubercles will distinguish the form from bistincta as well as other species of the genus having the narrow, elongated anal flap.

The species is dedicated to Mrs. Hazel Roberts who, with her husband Mr. H. Radclyffe Roberts, assisted in making collections on the Cerro San Felipe.

In the summer of 1938, I obtained a specimen of an undescribed Hyla at night, hopping along the edge of a small spring-fed rivulet at an elevation of about 2,300 meters on the Cerro San Felipe. The frog, frightened by my approach, jumped into the rivulet, swam to the opposite side and clambered up the bank, without attempting to hide under the water. Only by an examination of the terminal phalanges did I assure myself that this was not a specimen of the genus Cauphias, which it resembles in general habitus. The terminal phalanx is pointed and a small intercalated bone is present between the two distal phalanges.

Hyla robustofemora sp. nov.

Type. EHT-HMS No. 16314, adult male; collected on Cerro San Felipe about ten miles north of Oaxaca, Oaxaca, at an elevation of between seven and eight thousand feet, by Edward H. Taylor.

Diagnosis. Tympanum concealed, but indicated by a depression; no canthus rostralis; a heavy, thickened fold from posterior corner of eye to shoulder, with a branch to above insertion of arm; snout very short; the diameter of eye a third greater than snout length; no web or but the slightest indication of webs between fingers; toes webbed to the digital pads; a well-defined inner and a very dim, flat, outer metatarsal tubercle; a widened flap of skin on inner edge of first toe; anal flap not extending below level of the middle of femur; posterior face of femur not granular or areolate; no fold on breast; vomerine teeth in two rounded groups, which are double the

size of the small, transversely oval choanae; no vocal sac; nuptual ‘allosity covered with dark, horny asperities.

Description of type. Vomerine teeth in two rounded areas, sepa- rated from the choanae by a distance twice as great as the distance which separates the tooth groups; vomerine areas, reaching beyond anterior level of choanae and behind posterior level of choanae, double the area of a single choana; the teeth, four in number, irregu- larly seattered; openings of the mucous glands form a_ slightly

curved line, nearer the front rim of mouth than the choanae; a pig- ment spot behind the premaxillary region; skin of the roof of the mouth distinctly plicate behind vomerine teeth; tongue wide, sub- circular, very slightly emarginate posteriorly, free for about one- fourth of its length; no vocal sac (at least in the mouth no openings are discernible and there is no external evidence that a sac is present).

Head thick, short, much wider than long; snout distinctly shorter than eye; distance from eye to nostril, the distance between nostrils, and the width of the upper eyelid, are equal; interorbital width greater than that of an eyelid; a heavy thickened fold from eye to middle of body along side above arm, while a branch fold runs to

near arm insertion; skin of region behind jaw angle somewhat

thickened leaving a triangular depressed area. In this area is a very small deeper depression, perhaps indicating the position of a concealed tympanum; skin of the dorsal surface lacking tubercles: under the lens the skin is somewhat roughened with irregular cor- rugations while on the limbs and posterior part of the back the skin is more or less granular (a condition not evident to the naked eye) ; chin, abdomen and a patch on the proximal part of the ventral side of thigh, areolate, the large granules more or less equal; when arm

is extended a very slight axillary web evident; anal flap some- what elongate, narrowed, grooved medially; anal opening on a level with the middle of femur and followed by a deep groove.

Arms thick; fingers without a trace or only a faint trace of a web; first finger very short, reaching the subarticular tubercle of the second, greatly thickened and widened at base, bearing a large area covered with blackish, horny, nuptual asperities, which are con- tinued, on side of digit, to the pad; a similar patch on second finger, extending to the terminal pad; none on third finger; subarticular tubercle of outer finger not bifid; an elongate tubercle below the nuptual swelling; a large palmar tubercle more or less divided in

three parts; one tubercle under the forearm; legs thickened, the tibiotarsal articulation reaching to near the posterior corner of eye. Toes fully webbed (the last joint of the third toe on one foot, and on one side of the other, is free; I suspect this condition is due to an old injury and is not normal, since the fourth toes are webbed to the pad); a small, oval, inner metatarsal tubercle its length contained in its distance from tip of inner toe, three and one-half times; outer metatarsal tubercle small, flat, more or less indistinct; a more or less distinet, thickened, tarsal fold extends to heel; supernumerary tubercles on sole.

Color. Above, a uniform dull olive-green, somewhat hghter on side of head and body; chin, gray with yellow flecks; abdomen, creamy yellow with some pigmentation posteriorly, especially under posterior part of femur; palms and soles, dark lavender-gray; posterior side of femur gray with a wash of yellow; a cream spot under forearm; a few cream spots on side, on anterior face of femur, and at knee and heel; a dim spot of cream on anal flap.

Measurements in mm. Snout to vent, 55; length of snout, 4.3; length of head, 15.8; width of head, 19; diameter of eye, 5.15; eye to nostril, 4; width of upper eyelid, 4; interorbital space, 5; distance between nostrils, 4; distance between choanae 4.6; transverse di- ameter of choanae, 0.8; width of tongue, 11; width of a group of vomerine teeth, 1.6; arm, 35.3; leg, 86.2; tibia, 26.5; foot, 39; di- ameter of toe pad, 2.6; diameter of largest finger pad, 3.1.

Remarks. The general resemblance of this species to the descrip- tion of a form described by Brocchi as Cauphias crassum is rather striking, and were it not for the fact that Brocchi states—‘‘Les derniéres phalanges sont obtuses, tronquées A leur extrémité anté- rieure,” and Kellogg states ‘‘terminal phalanges T-shaped,” I might suspect I had before me a specimen of Cauphias closely related to crassum. However, the toes and terminal phalanges of this species resemble those of typical Hyla and a small intercalated plate is present between the last two phalanges.

The relationship of this species is closest to the species Hyla robertsorum from Hidalgo, with which it agrees in lacking a vocal sac, but from which it differs in having the concealed tympanum, the shorter, thicker femurs, shorter snout, the tiblotarsal articulation reaching to back of orbit instead of between orbit and nostril, and the feet almost completely webbed instead of about three-fourths webbed. The heavy, horny excrescences on the nuptual swelling on the base of first digits on hand are blackish-brown. From H. bis-

TayLor: New Mexican ANURA 393

fincta, it may be distinguished by the concealed tympanum, much vreater webbing on the toes, less developed canthus and the absence of a voeal sac. From other Mexican hylas, it may be distinguished by the absence of a vocal sac.

I obtained a large series of an undescribed species of the genus Hyla while collecting in the El Chico National Park, near Pachuca, Hidalgo, with Mr. and Mrs. Radelyffe Roberts. The specimens were found in plants along the tiny spring-fed rivulets that cross the open meadows. The leaves of the plants are large and at the base of the petiole small pockets of water are held. It was in this specific habitat that most of the specimens were found. The frogs were discovered early in the morning, at which time they were very inactive due to the cold. Later they became more active and if dis- turbed would dive into the water and take refuge in the mud at the bottom of the stream.

During the several days spent in the vicinity none was heard call- ing. Lacking a vocal sac it may be that the voice is weak and inaudible at a distance at which frogs may usually be heard. In the same habitat I obtained Hyla lafrentzu, Hyla eximia and a form belonging to the Rana pipiens complex.

I dedicate the species to Mr. and Mrs. Roberts, who helped collect the type series.

Hyla robertsorum sp. nov.

Holotype. EHT-HMS No. 16264; collected at El Chico National Park, Hidalgo, August 7, 1938, by Mr. and Mrs. Radelyffe Roberts and EK. H. Taylor.

Paratype. EHT-HMS Nos. 16265-16313, same place, date and collectors as the type.

outer more elongate one divided transversely ; subarticular tubercles of first and last fingers larger than those of the middle fingers: that of outer finger not bifid; supernumerary tubercles on palm; a few irregular tubercles on under surface of arm forming a longi- tudinal row; first finger reaches a little beyond the subarticular tubercle of the second finger; foot two-thirds to three-fourths webbed, the web continued to the pads as a narrow fringe; a well- defined fringe on outer side of fourth toe; a well-defined inner met- atarsal tubercle, flat, oval, its length contained in its distance from tip of first toe about three times; outer tubercle small, distinct; supernumerary tubercles confined to sole; a thickened tarsal fold extends to heel; a slight fold across breast; only a trace of an axillary web.

396 THE UNIVERSITY SCIENCE BULLETIN

Measurements of the holotype in mm. Snout to vent, 48; width of head, 16; length of head, 14.5; arm, 28.2; leg, 78; tibia, 25; foot, 36; width of finger pad, 2.8; of toe pad, 2.3.

Color. Above, dull olive to brownish-olive with numerous ashy flecks and reticulations; sides brown-ash with a few cream flecks; belly and underside of limbs dirty cream, the pigment thickest on chin and throat; concealed part of feet somewhat olive-yellow, with a few spots and reticulations of this color on the posterior side of foot; posterior face of femur olive with a yellowish wash.

Variations. The males have the base of the first finger greatly swollen, studded with minute spinules which are covered with a very shght, very light brown, horny deposit; a similar line of spinules on the inner edge of the second finger and a tiny patch on the third; a few specimens show no trace of web between fingers; in others there is a trace evident under the lens.

The vomerine teeth are in transverse groups in some specimens and are no longer than a choana. Certain specimens are blackish olive, and the venter and under side of limbs much more heavily pigmented; certain specimens have a few yellow flecks on or above the anal flap; in younger specimens the tibiotarsal joint reaches the anterior corner of eye or slightly beyond.

Remarks. The species needs to be compared only with the re- cently described species Hyla robustofemora. It differs from that species in the presence of a tympanum, the lesser webbing of the toes and the slenderer limbs; in H. robustofemora the feet are fully webbed. The two forms agree in lacking a vocal sac and in the character of the nuptual asperities, save that in H. robustofemora they are covered with heavy black-brown horn.

A species of frog, first discovered in the central part of Nuevo Leon, later in the southern part of that state and northern Hidalgo, appears to belong to the genus Syrrhophus Cope. It is distinetly larger than the other known species from Mexico, and two of the eight specimens show evidence of vomerine teeth. Otherwise the specimens agree in the characters associated with the genus.

The small, flat, inguinal gland commonly present in Syrrhophus (dim or wanting in S. marnocki) is present; a flat parotid-like glandular area behind tympanum; a ventral disk limited posteriorly by a transverse fold; finger and toes lacking distinct webs, and bear- ing the typical distribution of tubercles on sole and palm, cause me

Taytor: Netw Mexican ANURA 397

to associate the species with Syrrhophus rather than Eleuthero- dactylus.

The two specimens that have vomerine teeth are from southern Nuevo Leon, geographically intermediate between the other two localities. One specimen has the group of teeth present on one side only; in the specimen chosen for the type, on both sides. Only larger series from the type locality can determine the extent to which the teeth are present. That the whole series are of the same stock is shown by their close agreement in other characters.

Syrrhophus latodactylus sp. nov.

Holotype. EHT-HMS No. 6807, collected at Huasteca Canon, about 15 km. west of Monterrey, Nuevo Leén, Mexico, elevation about 680 meters, June 20, 1936, by Edward H. Taylor.

Paratypes. EHT-HMS No. 6805, near Sabinas Hidalgo, N. L. June 17, 1936; Nos. 6809-6812, La Placita (about 8 km. south Jacala, Hidalgo, July 1, 1936; E. H. Taylor, collector).

Diagnosis. A large member of the genus, maximum size 38.2 mm.; tympanum two-thirds to three-fourths the diameter of eye; vomerine teeth present or absent; a small flat gland above groin and a small, flat parotoid; head wider than body; largest digital disks about two and one-half to three times narrowest width of digit; yellowish or light lavender above with deep brown spots or reticulations.

Description of the type. Adult female containing large eggs in ovaries. Head as broad as long, the snout narrowing, then slightly truncate at tip; canthus rostralis rounded, the lores sloping slightly, not concave; eyelid contained in the interorbital distance about one and one-half times; length of eye about equal to its distance from nostril, shorter than snout; diameter of the tympanum (3 mm.) equal to two-thirds the length of the eye (4.5 mm.); distance be- tween nostrils (3 mm.) much less than interorbital distance (5 mm.); tongue rather short, somewhat narrowed anteriorly, not notched behind; two small groups of vomerine teeth, each about as long as the greatest diameter of choanae, separated from each other by a distance greater than length of either group and from choanae by a still greater distance, both groups lying much behind the posterior level of choanae; mucous glands open by a series of pores directly between the middle of the choanae; choanae large, diameter 1.2 mm.

Skin above on head nearly smooth; on back and upper sides of body with very small inconspicuous pustules; chin, breast, and en-

toes with well-developed supernumerary tubercles on sole; a slight (or sometimes deep) transverse groove is evident on the tips of toes; tibiotarsal articulation when brought forward reaches middle of eye.

Color in life. Above light lavender to yellowish-gray with dark brown or blackish-brown spots and reticulations on dorsal and lateral surfaces, and above limbs. Abdomen and most of underside of femur immaculate cream; a very fine peppering of seattered pigment on chin, low on sides of body and under the tibia, hand and foot; a more or less indistinct dark band from nostril to eye, and a spot, bordering tympanum above, usually conspicuous; posterior part of femur with some scattered fine dark pigment and a few small spots about anus.

Measurements in mm. Nos. 6807, 6811, 6810, 6806; snout to vent, 38.2, 35, 32, 32; width of head, 15.2, 13, 13.8, 13.2; length of head, 14.9, 12.8, 12.9, 12.5; diameter of tympanum, 3.1, 2.5, 3, 3; length of eye, 5, 4.2, 4.05, 4.3; eye to tip of snout, 7.5, 5.8, 6.5, 6.1; arm, 24.3, 23.8, 23-2, 19.5; wadth of largest: pad, 28,2) 2) 2 leg. 56, 5ac204 oF ADs ibian | TO aliale 1595 Los foot .2a, 2oOcU.on aie

Variation. The specimens agree in most essential characters. Those from the higher more southern localities seem to be more lavender on the dorsal surfaces; those from the more northern and lower localities, more yellowish. After two years of preservation they are practically indistinguishable in color. In the specimen from Sabinas Hidalgo, the spotting on the hind limbs is practically obso- lete. Variation in presence or absence of teeth has been mentioned. Other variations are discernible from the table of measurements.

Remarks. The widening of the digital pads is greater propor- tionally than in any other Mexican form referred to, Syrrhophus, Tomodactylus, or Eleutherodactylus, with the exception of those of Eleutherodactylus alfredi and E. spatulatus.

The first specimen of the species was found hopping among boulders in a dry stream bed, about four kilometers from the town of Sabinas Hidalgo. This locality is about 345 meters in elevation. The type and one other specimen were obtained from the exposed low rock masses near the entrance of Huasteca Canon, near Mon- terrey. Both were found at the edges of deep crevices into which other specimens seen, escaped. The elevation here is about 680 meters. At La Placita (a station marked on the highway without houses) the specimens were found at night among outcropping boulders in oak forest at an elevation of about 1,700 meters.

The large eggs found in the ovaries suggest a shortened life history.

With the discovery of more forms in this and the related genera Tomodactylus and Eleutherodactylus (sensu lata) which suggest characters intermediate between them, it will become increasingly difficult to maintain these genera under their present definitions. This is particularly true of Syrrhophus and Tomodactylus whose differentiation depends upon a difference in the development or shape of the gland in the upper inguinal or lumbar region.

New Salamanders from Mexico with a Discussion of Certain Known Forms

EDWARD H. TAYLOR, Department of Zodlogy, University of Kansas

Apstract: Seven new species of salamanders are described from Mexico: Bolitoglossa dimidiata (chiroptera group), Guerrero, Hidalgo; Thorius pulmo- naris, Cerro San Felipe, Oaxaca, Oaxaca; Thorius narisovalis (related to pennat- ulus), Cerro San Felipe, Oaxaca, Oaxaca; Ambystoma bombypella (tigrinum group), Rancho Guadalupe, 14 km. east of San Martin, México; Ambystoma ordinaria (tigrinum group), near Puerto Hondo, Michoacan; Ambystoma am- blycephala (tigrinum group), 15km. W. of Morelia, Michoacan; Siredon ler- maensis, Lake Lerma near Toluca, México.

Thorius pennatulus Cope is discussed and figures given showing variation ; Siredon dumerilii and Siredon mexicana Shaw are discussed. A figure is given of an artificially transformed specimen presumably of Siredon mexicana Shaw. Figures are given of all new species.

SERIES of about thirty specimens of a tiny salamander was taken in the mountains to the northeast of Pachuca, Hidalgo. The first specimens were encountered under logs, occasionally under the same logs as Bolitoglossa multidentata (Taylor) in the El Chico, Parke Nacional. Later they were found at a somewhat lower ele- vation a few kilometers north of the park, at a point about four kilometers below Mineral del Monte, known to the natives as Guer- rero. It is the ruins of a great machinery factory. Although this name has appeared before in the literature of Mexican salamanders (Dunn 1926), I believe that none of the recent maps give its location. This form has been confused with Oedipus townsend in the litera- ture, but differs from that form in having a distinctly different type of foot and hand, belonging to the chiropterus group of Bolitoglossa rather than to Thorius.

or a little longer; groove from under eye does not reach edge of upper lip; limbs separated by about four (five occasionally in females) costal folds; width of head in snout to vent length about six times; first toe shorter than fifth; a projecting growth from cloaca in males.

Description of the holotype. WHead rather flat between orbits and in occipital region; snout rather rounded at tip, but the curving line seen from above is broken by the subnarial swellings; no canthus rostralis; nostrils large, directed forward, their diameter contained in distance from the eye about twice; distance between nostrils (1 mm.) minutely greater than distance from eye to nostrils; inter-

orbital distance (1.6 mm.) greater than the width of an eyelid (1 mm.); length of eve (1.6 mm.) equal to the length of the snout (1.6 mm.); subnarial swellings relatively very large, prominent; a well-defined hedonic gland on the chin; tongue typical with a well- defined sublingual fold; four-five maxillary teeth confined to region under the subnarial swellings; three teeth pierce the edge of lip on premaxillary; mandibular teeth enlarged, irregular, seven on each side; vomerine teeth three or four on each side in two somewhat curved diagonal series not extending beyond the outer level of choanae; parasphenoid teeth in a single group, narrowed anteriorly, widening posteriorly, and notched behind; separated from the vo- merine teeth by a distance about four times the diameter of a choana.

The groove below eyelid terminates below the posterior part of eye about midway between eye and mouth (not reaching lip as in most if not all of the members of the genus Thorius) ; groove running back from angle of eye more or less distinct (if slightly dried the groove appears); first transverse groove crosses down behind the mouth angle and across anterior part of throat; a well-defined nuchal fold crosses throat and is continued on sides of neck as an irregular groove; growing less distinct, it meets the groove from opposite side; on each side of the dorsolateral region of neck, con- necting the two transverse grooves, are two longitudinal grooves (the upper irregular) ; the area between them is divided into two unequal areas by a short transverse groove which continues a little on the dorsal side of neck; thirteen costal grooves, the axillary and inguinal more or less distinct; the posterior extension of the hyoid apparatus below skin makes a broad fold on side of neck; it terminates pos- terior by arm insertion; a constriction on base of tail more or less developed; about twenty grooves visible on proximal part of tail; a glandular spot behind insertion of femur; cloacal walls with numer- ous minute papillae.

Limbs short, when adpressed, separated by about four (or slightly less) costal folds; hand with digits webbed at base, the fingers moderately widened, the terminal phalanx and part of the adjoining phalanx free in the three outer fingers; tip of first finger not free; pads on ventral surface of tips of digits swollen; foot with inner toe involved in the web; outer toe very short, but with tip protruding from web; three middle toes each with at least the outer phalanx free,

Above uniform lavender with a small, somewhat reddish spot on the dorsal surface of the femur; below dirty cream- white with a scattering of pigment; subnarial swellings creamy white; a few minute flecks of white on sides; indication of a buff spot behind transverse groove. or dorsal side of neck.

Measurements in mm. Nos. 17677, 17674; sex ¢, 4; snout to anterior part of vent, 24.7, 23.3; anterior end of vent to tip of tail, 28.4, 25.2; head width, 4, 4; head length to nuchal fold, 6.2, 5.5; axilla to groin, 14, 13.8; arm, 5.1, 4.65; leg, 5.6, 5.5.

Variation. Males, for the most part, agree with the description ; females differ in being somewhat darker in coloration above, the

fawn-colored spot on the neck being usually distinct. The ventral surfaces are often much more pigmented with yellow-cream flecks visible on chin and throat.

Females differ in having larger series of jaw teeth. In No. 17700 there are 19-19 maxillary teeth; vomerine teeth, 4-4; premaxillary teeth, 6; mandibular teeth, 18-19. The nostrils in females are about the same size as those in the male type, but the subnarial swellings are scarcely noticeable. The limbs of females are proportionally shorter compared with the axilla to groin distance and are separated in adult females by about four and one-half to five folds.

The males have one or two fleshy protuberances from the postero- dorsal wall of the cloaca, the significance of which is not known. They strongly suggest some type of intromittent organ. A similar growth, less conspicuous, is present in the cloaca of B. chiroptera, lending weight to the suggestion of close relationship between the forms.

Taytor: Nrw SALAMANDERS FROM MExICcO 41]

One specimen, No. 17674 (measurements given), has the snout broader, the nostrils directed completely forward, the eye a third longer than the snout; and there appears to be a shght difference in the character of the toes. It was collected in a lot with several others in the same pile of leaves and agrees with the others in characters not mentioned. It is likely that the differences are anomalous (figured).

There is a specimen of this species in the Harvard collection, (No. 8018) one of the type series of Oedipus townsendi from Guerrero, Hidalgo, and two specimens numbered No. 67654, from Hidalgo.

It can be separated from B. multidentata by the enlarged nostril and the much shorter legs and smaller body; from B. chiroptera by the enlarged nostril (which remains large in the adult), and by a somewhat smaller size.

Living among the wet leaves on the ground at an elevation above 2,000 meters on the Cerro San Felipe near Oaxaca, I discovered a tiny salamander with a very large, elongated nostril which appears to be an undescribed species.

and occipital region somewhat curving. Tongue boletoid; a free projecting sublingual fold; four premaxillary teeth; no teeth dis- cernible on the maxilla; mandibular teeth present; twelve vomerine teeth arranged in a single elevated median patch, partly in two rows, not extending outward beyond the inner edge of choanae; the cho- anae are narrow slits; parasphenoid teeth in a single elongate patch which is somewhat tongue-shaped, not notched behind, the group separated from the vomerine teeth by a distance nearly equal to the width of the vomerine series.

Skin above generally smooth, but with pitting on the head; pits on snout very distinct; on back, pits are smaller, less distinet; thir- teen costal grooves (including the distinct axillary and inguinal grooves) ; twelve costal folds; limbs small, separated when adpressed

Color. Above lavender-slate, below dirty whitish to lavender- brown, less heavily pigmented under tail (sometimes darker brownish or lavender below) ; a series of small light flecks on chin and oceca- sional ones scattered on ventral surfaces; a few minute whitish flecks on sides; subnarial swelling and a spot on lower eyelid, whitish.

Measurements in mm. Nos. 16684, 16712, 16733; sex, Oe Cree a snout to posterior end of vent, 24.4, 27.2, 27.5; tail from posterior end of vent, 35, 35.6, 36; width of head, 4, 4.3; 4.2; length of head, 9.3, 6.1, 6; snout to gular fold, 4.8, 5.4, 5.2: arm, 4.2, 5.6, 4.7; leg, 4.4, 4.6, 5.2; axilla to groin, 15, 14, 15.

Variation. The largest specimen has the maximum snout to (pos- terior part of) vent length of 27.5 mm. and a maximum total length of 63.5 mm. Males have longer snouts and shorter axilla to groin measurements, resulting in having adpressed limbs closer together. In some of the specimens the vomerine teeth are larger, varying in number from as low as four or five teeth in some males to eight in

others, always in a transverse or slightly V-shaped series. They do not seem to be separated medially and only occasionally are there two rows present,

Remarks. Specimens were found at an elevation of about 2,000 meters on the mountain under leaves and trash on the ground. They were very unequally distributed. Higher on the mountain they are replaced by Thorius narisovalis, a form with an enlarged nostril that is about half the diameter of the present species, and living al- most exclusively under bark and logs.

The very large nostril and the great amount of surface on the nasal walls suggest that the nasal passage may be used for direct exchange of oxygen in respiration. In males the size of the nostril is only slightly larger than in females of similar length.

A number of specimens taken at the mountain pass about three kilometers southwest of Acultzingo have been referred to this species.

Some were found under rocks in crevices in moist clay along the edge of the old cobblestone pavement. Others were taken a few hundred feet higher in the thick moss under a lone pine tree near the summit. The behavior of the two groups of specimens was different; those taken in the moss were usually coiled in a watech- spring spiral as if imitating the spirally coiled millipeds which infest the moss and which are about the same size as the smaller salaman- ders. Those taken under rocks in clay were not so coiled.

In the preserving fluids, those taken in the moss seemed to become rigid and distorted at death, the musculature of the side of the head and neck appearing quite distinctly through the skin, and the posterior projection from the hyoid stands out very clearly. (See DE eB)

Those taken in the clay remained without distortion when pre- served, showing little or no trace of the lateral neck musculature or cartilage. In these specimens the terminal part of the tail was white, which on examination proved to be due to a white parasitic worm which was just beneath the epidermis. These worms are an

TayLtor: NEw SALAMANDERS FROM MExIco 415

immature stage in the life history of some unknown cestode, They are from two to four millimeters long. They have not been identi- fied. No worms were found in specimens taken in the moss.

The following specimens are referred to Thorius pennatulus: EHT-HMS. Nos. 17731-17786; 17788-17793.

The two lots of material from this same general locality are some- what puzzling.

They differ in the amount of pitting on the head, those from the moss being almost wholly smooth save behind eye and on neck. These specimens likewise have the vomerine teeth set on a higher ridge and the deep groove from below eye intersects the mouth at a point slightly farther forward. These may represent two distinct species, but I feel that further study on live material is necessary

to determine this point. The types are apparently lost and new topotypic material must be obtained to deal satisfactorily with these diminutive salamanders.

I have examined the specimens in the U. 8. National Museum referred to this species. All are old and for the most part badly preserved. Certain ones I believe belong to different species.

I cannot identify it certainly with any species. Nos. 30348-30349 Tehuantepec, Sumichrast Coll. are two fragmentary specimens, at least one of which, represented by a head, belongs to a species having the “sharp snout.” If this specl- men actually originated in Tehuantepec it is likely that it is an undescribed form, perhaps related to the sharp-nosed salamanders

of Central and South America. The British Museum specimens listed by Dunn (op. cit. p. 439) from Cerro San Felipe, Oaxaca, may likewise be referable to another form.

The specimen figured by Boulenger (loc. cit.) if correctly drawn,, cannot belong to the species at hand; the dark lateral band, whitish- margined above, and the absence of the deep groove from below eye to mouth, strongly suggests another species.

Type. EHT-HMS No. 17859; collected at an elevation of about 2,600-3,000 meters on Cerro San Felipe, 15 km. north of Oaxaea, Oaxaca, August 18-22, 1938, by Edward H. Taylor.

Paratypes. EHT-HMS Nos. 17794-17858; 17860-17870; same date, locality and collector.

Diagnosis. A diminutive species related to Thorius pennatulus, but differing in being larger and in having the dorsal part of head covered with relatively large pits; the groove below eye normally intersects the line of mouth slightly posterior to the posterior corner of the eye. No teeth on maxillary. Fingers and toes better de- veloped, with a greater degree of independence, than pennatulus.

Description of the type. Adult female. Head not wider than the body, and less deep; the distance between the orbits less than the width of a single eyelid; nostril oval about .56 mm. in greatest diameter, its distance from the extreme tip of snout equal to less than half diameter; length of eye 1.45mm.; a very minute fold back of eye under which the posterior part of eyelids terminate; length of eye greater than length of snout (1.3 mm.); occipital region rather flat, with shght depressions next to orbits; a groove behind eye continues to near the nuchal groove; a strong groove below eye intersects the line of mouth behind posterior corner of eye; snout somewhat narrowed anteriorly, but not “sharp” or “pointed”; subnarial swellings prominent for a female; snout pro- jecting very moderately beyond mouth; line of mouth diagonal, angulated near narial swelling and at point of intersection with the subocular groove; a strongly defined transverse groove crosses throat and up across sides of head to dorsal surface; a groove, in the form of an arch on chin, which rests on the transverse groove; a strong nuchal fold across throat which continues diagonally backward across the side of neck to near dorsal surface where it is again di- rected transversely but fails to completely cross the medial part of the dorsal surface; on the side of the neck there is an elongate fold,

or ridge, which terminates posteriorly at the groove from the nuchal fold; behind this the posterior hyoid extension makes a prominent raised fold which continues to the second costal groove, the carti- lage itself terminating before this point; 13 costal grooves, 12 folds; 33 folds from hind legs to tip of tail; tail constricted at base, more or less circular proximally then laterally compressed distally; a more or less distinct median dorsal groove present on body; ad- pressed limbs separated by six costal folds; fingers in the following increasing order of size, 4, 1, 2, 3; the toes, 5, 1, 2, 4, 3; only ex- treme tip of first finger free, while the two middle fingers are free for nearly half their length beyond metacarpals; extreme tip of first and fifth toes free; three middle toes free for about half their length beyond metatarsals; terminal pads on tips of digits moder- ately prominent. Tongue boletoid, free, a sublingual fold; three premaxillary teeth not piercing the lip; no maxillary teeth; vomer- ine teeth four on each side, on a strongly elevated narrow ridge; choanae small, no wider than the narrow, deep grooves emerging from them; 19-20 mandibular teeth; parasphenoid teeth in a single group narrowed greatly anteriorly, widened posteriorly without or with only a very slight posterior median notch, separated from vomerine teeth by a distance equal to the vomerine series. Dorsal and lateral regions of head strongly pitted; dorsal surface of body with the pitting less distinct; a slight wrinkling on the sides between the costal folds; tail pitted and with shght corrugation; smooth or dimly pitted on ventral surfaces.

Coloration. Reddish-brown on entire dorsal surface of body and tail; sides blackish, head dark; venter lighter, gray-brown, with a few cream dots; the dorsal and lateral markings rather strongly contrasted in life, but in preservatives are indistinct unless sub- merged in water.

Measurements in mm. Type, 17859; largest female, 17819; and largest male, 17854, respectively. Snout to posterior end of vent, 28.8, 31, 27.5; tail, 32.5, 40 (estimated, the tail broken and regeneration begun), 35; snout to arm, 7.8, 8, 7.5; axilla to groin, 16.8, 17.5, 16; arm, 4.3, 4.8, 4.3; leg, 4.6, 5.3, 4.8; width of head, 4.2, 4.5, 4; snout to nuchal fold, 5, 5.6, 5.15.

Variation. Adpressed limbs are separated by from four and one- half to six folds, the larger number being in larger females; the lower, in smaller males. In color some of the females are blackish above, lacking the dorsal reddish-brown mark. A few have tiny

orange-brown stripes on each side of the medial line with a separate nuchal spot.

In many specimens the subnarial swellings of females were as large as in the males. In larger males from one to three of the pre- maxillary teeth pierce the lip. In most of the specimens the lateral grooves of nuchal fold meet on the middorsal line. The number of segments on tail varies between 22 in the smallest specimen (15 mm. snout to end of vent), to 36 in a large female (29.5 mm. snout to end of vent). One case showed the groove, from nostril to lip, eut com- pletely through the lip to choana.

Remarks. The specimens of this species were found under the bark on fallen trees together with Bolitoglossa smithi and Bolito- glossa unguidentis from the same locality. Only one or two were found on the ground under logs. Thorius pulmonaris, the other rep- resentative of the genus Thorius found on San Felipe, was invariably found in wet leaves on the ground, but at a lower elevation than the other species mentioned. The Thorius narisovalis were more active than the other species, usually starting for cover when they were exposed by the removal of the bark. When touched they would jump or throw themselves from the log to the ground and hasten to ensconce themselves under leaves or other debris. At no time did I find them passive or coiled.

Taytor: Netw SALAMANDERS FROM Mexico 419

Description of type. Head low, the line of the mouth forming a slightly sigmoid line; length of eye less than its distance from nos- tril; interorbital distance slightly less than length of snout; distance between nostrils less than interorbital distance; eyelid in interorbital distance three and one-half times; a slight groove behind eye can be traced back to end of the gular fold; a vertical groove crossing angle of jaw barely indicated; gular fold present; tongue broad, the lamellae radiating forward; choanae large, the diameter of one con- tained in the distance between them, four and one-half times.

Palatine teeth 12-10, not reaching forward to the level of the mid- dle of choanae; vomerine teeth 15-17, the series forming a broad angle not or but scarcely separated medially; a circular depression in middle of palate about half diameter of a choana; maxillary- premaxillary teeth 56-54; mandibular teeth about 60-60; 12 costal grooves, 11 folds; no splenial teeth; limbs well developed, over- lapping length of hand (in paratype, to elbow); digits flattened, terminating in fine rounded points with a very slight terminal dep- osition of horn; phalangeal formula of fingers, 2, 2, 3, 2; of toes, 2, 2, 3, 4, 2.

Skin rather shiny or silky in appearance due to very fine reticu- lated striations; head with a few enlarged pits above and anterior to orbits; trace of the lateral line organs on body dimly discernible in type (more so in the younger ? paratype).

Measurements of type and paratype in mm. Nos. 3997, 3998; sex, 2, 25; snout to vent, 81, 67; tail, 61, 52.3; snout length, 8.4, 5.8; snout to gular fold, ventral, 20.2, 17; snout to arm insertion, 28.5, 23.5; axilla to groin, 36.5, 29.5; eyelid width, 2.1, 2.1; interorbital width, 6.8, 5.3; distance between nostrils, 5.5, 4.6; arm, 24.3, 22.3; leg, 26.6, 24.8.

Color in life. Above uniform grayish-brown to lavender-brown, with a faint, very narrow, median, dark line from shoulder to base of tail; a slight darker line follows the diagonal groove behind eyes; lower half of sides of body and tail light tan or brownish-white; abdomen grayish to brownish-white; chin cream-yellow.

Variation. A single paratype, somewhat smaller than the type, agrees in most characters. The color above is somewhat more laven- der and the tail shows some indefinite darker spotting; the teeth are as follows: maxillary-premaxillary, 41-38, the series not extending so far posteriorly as in type; mandibular teeth about 48-48; vomero- palatine series, 7+ 14, —7-+ 16, the vomerine groups forming a curving series slightly broken medially; the depression in the palate

420) THe UNIVERSITY SCIENCE BULLETIN

is very much wider and shallower; there is no trace of a dark line behind eye.

Remarks. The type and paratype were taken on a hillside near a small permanent artificial pond. They were under rotting logs. In the immediate vicinity I also found the single type specimen of Ambystoma schmidti Taylor, a species, if one may judge by the teeth, related to Ambystoma texanum (Matthes). The form here described is related to the tigrinwm group, but may be readily dis- tinguished by the fine texture of the skin, and coloration. While resembling Ryacosiredon in certain characters, the absence of larval dental characters precludes an association with this genus.

Paratypes. EHT-HMS No. 16442, 16444. ‘Topotypes.

Diagnosis. A rather large species with 11 costal grooves; caudal fin tending to disappear save for a fine ridge; web between meta- tarsals and metacarpals distinct; fingers free to a point near distal ends of the metacarpals; metatarsals included completely in web; phalanges free, fingers and toes with a slight fringe; limbs overlap distance equal to hand; 31 to 37 palatine and vomerine teeth on each side; teeth more or less bifid, in a low-arched transverse series; 70-80 maxillary-premaxillary teeth, in full-grown adults, on each side; mandibular teeth about same; lateral edges of tongue free.

Description of the type. Head longer than broad, much more than twice as wide as deep. Distance between eyes (7.2 mm.) less than length of snout (8.2 mm.); length of orbit (4.1 mm.) less than distance to nostril; nuchal fold distinct; a transverse groove across jaw angle. Maxillary-premaxillary series of teeth 72-70, the teeth extending some distance behind the level of the palatine teeth; mandibular teeth about as numerous; palatine and vomerine teeth in a practically continuous series on a transverse elevated ridge, which forms a very slightly elevated arch, the most anterior teeth not reaching the anterior level of choanae; about 67 teeth altogether, the tips brownish; palate with a broad, shallow medial groove, with a rounded cavity posteriorly in which the openings of the mucous glands are discernible; tongue lamellate, the plicae running longi- tudinally, the edge free laterally.

Skin of head with minute pits, and a few large pits on each side between orbits and running forward; and another scattered series of

Taytor: New SALAMANDERS FROM Mexico 421

large pits more or less surrounding lower part of orbit; no traces or only dim traces of the lateral line system on body. Adpressed limbs overlap length of hand; digits webbed between metacarpals and metatarsals, the web failing to reach the ends of metacarpals but completely includes the metatarsals; a very slight fringe on the sides of the digits, the tips more or less covered with a horny deposit; two metacarpal tubercles and two metatarsal tubercles; tail lacking a dorsal fin save for a slight dorsal ridge; tail as long as body, exclud- ing head.

Color. Above, blackish; below, gray with a series of ventrolateral cream spots; the median ventral region a little darker. Breast and throat with some cream markings. Sides of the proximal part of tail of lighter color than distal part.

Measurements in mm. Nos. 16448, 16442, 16444; sex, 9, 9, 2; snout to posterior end of vent, 90, 93, 64.5; tail, 71, 60, 47; width of head, 17.5, 16.5, 13.5; length of head, 18.5, 20, 16; snout to nuchal fold, 22, 22, 16.2; snout to arm, 28, 30, 27; leg, 30, 33.2, 27.1.

Remarks. All three specimens are slightly shriveled, due to having been preserved some time after death. Normal condition of the surface of the body is somewhat uncertain. The smallest speci- men has a smaller number of maxillary and mandibular teeth, as is true of the young of many species, the series increasing posteriorly in older specimens as the jaw grows. The vomerine teeth form a higher arch, the anterior teeth reaching farther forward than the anterior level of the choanae. The two paratypes do not have the series of cream spots as pronounced as in type and the tails are somewhat more slender, darker, and the dorsal fin is somewhat more prominent in the younger specimen. The larvae are unknown.

From Ambystoma bombypella the species differs in color (prob- ably also in skin texture) and in having a very much greater num- ber of jaw teeth. The arrangement of the vomero-palatine series is different. In bombypella the palatine teeth are separated from the angular vomerine series.

From Ambystoma ordinaria it differs in having nearly double the number of teeth in the adults, and likewise differs in the number and arrangement of the vomerine and palatine teeth. The webbing extends between digits to the base of the metacarpals and metatar- sals, which is not true in ordinaria. I have compared these three forms with transformed Siredon mexicana from which all differ in shape of head, skin character, body proportions. A figure of that form is included for comparison.

Diagnosis. A rather large salamander with eleven costal grooves from axilla to groin; limbs, when adpressed, overlapping a distance equal to length of hand, or arm to elbow; digits unwebbed, free as far as from one-third to one-half of the metacarpals and metatarsals; caudal fin persistent, tips of digits more or less covered with horn; premaxillary-maxillary tooth series 39-46 on each side of jaw; 9 to 11 palatine teeth more or less separated from the vomerine series which is either in a single curved series or divided into two diagonal groups. Adults uniformly grayish-black above, somewhat lighter laterally and on belly.

Description of type. Head longer than broad, and much wider than deep; distance between the eyes (9 mm.) greater than length of snout (7.3 mm.); length of orbit (5 mm.) equal to distance to nostril; maxillary-premaxillary teeth, 47-42, the teeth extending back to the posterior level of the palatine series; the individual teeth directed mesially; palatine teeth in a group of 10-12 on each side, separated from the vomerine series by a diastema; about 27 teeth in the vomerine group, which is continuous and curving; mandibular teeth, 48-48; many of the teeth in both upper and lower series slightly bifid; tongue large, lamellated, the plicae running longi- tudinally ; tongue free on sides.

Body about as deep as wide; head much wider than deep; arm rather short, failing to reach beyond tip of snout; digits tipped with horn, in the following order of size: fingers, 1, 4, 2, 3; toes, 1, 5, 2, 3, 4; two palmar (metacarpal) tubercles; a pair of metatarsal tu- bercles. Skin on head minutely corrugated and pitted; traces of the lateral-line organs on head and body inconspicuous or absent.

In general appearance the two adult paratypes are similar. In both, however, the third toe is slightly longer than the fourth, instead of shorter, and traces of the lateral line organs persist as a series of minute openings which are slightly elevated and which are frequently white in color; these are confined to the lateral and ventro-lateral rows, the latter continued on the breast.

In No. 16366, ¢ , a few spots are also visible in the dorso-lateral row.

The male (No. 16365) has an enlarged, flattened cloacal gland. As is typical of the males of most salamanders this specimen has longer limbs, the adpressed limbs overlapping nearly to the elbow. In all the specimens the caudal fin is only slightly narrower than the fleshy part of the tail.

Larvae. In the larval specimens, all collected with the type in a tiny stream, near its headwaters, I find two groups of larvae which I interpret as normal and neotenic forms. The entire series ranges from tiny specimens 25 mm. (snout to posterior part of vent) in length, to the large neotenic forms 87 mm. long. The specimen hay- ing the greatest length contains fully developed eggs in the ovaries which are equally as large, and similarly colored to those present in the type specimen.

The younger larvae have the lateral line organs in three series, a dorsolateral, a lateral, and a ventrolateral, the last continued onto the breast. These are usually conspicuous due to the presence of white or cream spots about their external openings. In many larger and some of the smaller larvae the light spots are wanting. In some of the larvae the tails are longer than head and body.

Another variation is evident in the vomerine series. Part of the longer and shorter tailed forms have the teeth in a continuous arch; and part have the series distinctly divided. This variation is evi- dent too in the transformed specimen. The type, a female, differs from the other adult male and female. The adults were taken under water with the larvae.

Two larval specimens are figured with the type. It is possible the type transformed from a neotenic specimen, the two other adult specimens from subadult larvae. In the very young larvae (25 mm.) the dorsal fin extends to the shoulders but it has disappeared on body when the larvae have reached about 40-45 mm., the caudal fin termi- nating abruptly near insertion of the hind legs.

The differences between this form and Ambystoma amblycephala

424 THE UNIVERSITY SCIENCE BULLETIN

.

are discussed under that form; from bombypella it differs in the character of skin, coloration and the arrangement of the palatine and vomerine teeth.

I am not certain whether the small stream in which the specimens were found, empties into the drainage system of the Balsas river or that of the Lerma (Rio Grande) river. The elevation was about 9,000 feet, and may be near the divide between the two systems.

This species, the form of Siredon longest known, appears to be confined, normally, to certain lakes and swamps of the Valley of Mexico. A series of ten were purchased at Lake Xochomilco in 1938. These are EHT-HMS Nos. 18946-18955.

Description. A large neotenic salamander with head broader than long. The maxillary-premaxillary teeth vary from 42-51 on each side of jaw, the teeth extending slightly behind the posterior level of choanae; mandibular teeth 48-52 on each side, the posterior teeth of the series somewhat enlarged; palatine teeth in straight, nearly parallel series, containing from 8 to 16 teeth, the smaller number in the older specimens; vomerine series consist of from 24 to 32 teeth on each side, the series directed diagonally forward, but are separated medially by a distance somewhat less than half the length of a single series. The teeth are often arranged in short diagonal rows rather than in a serial line; vomerine teeth separated from the palatine by a diastema; 28 to 38 splenial teeth, the posterior teeth arranged in short diagonal series of three or four teeth. The smaller numbers are in the older specimens. (In very old specimens it may be that most of the splenial teeth are lost or covered by the gums.)

Skin moderately smooth, the pitting on head and body rather indistinct or obsolete in most cases, the head occasionally with a few small craterlike pits; occasionally the skin has a slightly granu- lated appearance. The dorsal fin inserts anteriorly at a point more than a centimeter behind the posterior gill insertion; anteriorly the fin is a little more than a low fold, but on tail it rises to a height of several millimeters; tail sharply pointed at distal end; limbs, when adpressed, overlapping about the length of the foot, or less in fe- males filled with eggs; digits including the distal part of the

Taytorn: New SALAMANDERS FROM Mexico 425

metatarsals and a still larger part of the metacarpals, free, the digits flat and pointed. A pair of metatarsal tubercles and a pair of metacarpal tubercles normally present, but one or another may be absent. Males have an enlarged cloacal gland, which is reduced in females.

Measurements in mm. Largest male, 18954, largest female, 18950; snout to posterior end of vent, 132, 125; tail, 95, 85; snout to arm, 43; 45; axilla to groin, 58, 62; width of head, 33, 37; length of head, 44.4, 45; arm, 36, 38; leg, 40, 38; nuchal fold free, 8, 10.

Transformed adult. (Field Museum Natural History No. 19179.) I do not have the history of this specimen. The label states “Mexico City, Mexico, Coll. Emil Witschi, July 1933.” Mr. Karl Schmidt states that he believes that the specimen was artificially trans- formed.

This specimen is squat, the body short, plump, and the head very short and wide. The tail is much shorter than head and body; distance between the eyes (10.2 mm.) distinctly longer than snout (7.4 mm.) ; a few faint traces of pits are discernible; nostrils rather narrow, elongate, the distance between them greater than their distance from the eye.

Maxillary-premaxillary teeth 63-63; palatine teeth 7-7 on each side in a nearly straight, transverse line; vomerine teeth about 11- 13, the series tending to form a very broad angle, but with a slight diastema medially; a median well-like cavity in the palate; choanae rather large; tongue large, the lamellae parallel for the most part; about 60-60 mandibular teeth.

Digits rather short, pointed, free on foot to near the distal end of the metatarsals, on hand, the distal tip of the metacarpals free; a well-developed inner metacarpal tubercle, the outer apparently wanting; a strong inner metatarsal tubercle, the outer barely in- dicated; digits in the following ascending order of size: fingers, 1, 4, 2, 3; toes, 1, 5, 2, 4, 3; adpressed limbs overlap the length of foot; 11 costal folds. Tail strongly compressed without trace of a mem- branous fin; dorsally skin smooth, but on sides of head and body, as well as on tail, it is granular.

Deep brown on dorsal surface of head, dorsal and half of the lateral region of body and on tail; yellowish, low on sides and chin; muddy yellow on abdomen. The body above and below with scattered large black spots; tip of digits light.

Measurements. Snout to posterior end of vent, 87.5; tail, 67.2; snout to foreleg, 29; axilla to groin, 45; width of head, 25.2; length of head, 27; snout to nuchal fold, 20.2.

This very striking species is known only from Lake Patzcuaro, Michoacan. It is unknown in a transformed state.

Diagnosis. A large perinnibranchiate; reddish-violet mixed with

brown, much lighter below. Body short, flattened somewhat; head much flattened; 12 costal folds; four gill openings; three gills; ad- pressed limbs overlap the length of foot; ventral fold on neck free medially for 5mm; large number of shallow crater-like pits on head, neck and to a much lesser extent elsewhere on back, sides, and ven- ter, giving surface a somewhat corrugated appearance; fingers united by a web involving proximal phalanx.

Description. USNM. No. 16201. (Reputed to be from Guana- juato, México, Dugés, collector. It is possible that this specimen may have actually been before Dugés when he described the species. He designates no type. It seems certain that this specimen originated in Lake Patzcuaro and was sent to the U. 8. National Museum from the Guanajuato locality by Dugés.)

Head broad and flat, its length about a fifth longer than broad; to edge of the ‘‘ventral fold” 29mm. Ventral fold has a free edge medially for about 5mm., maxillary-premaxillary tooth series 64- 63 (counting an occasional missing tooth); palatine teeth 24-23, vomerine teeth, 37-38; the vomero-palatine series nearly continuous on the left side, the two series separated medially by a short dis- tance; about 50-48 splenial teeth; mandibular teeth 70-89.

The dorsal fin arises about 10 mm. back of the level of arm in- sertion; on body, it is very low, but on the tail reaches a height of 6mm. above, and about 3.5mm. below tail. The maximum width of the tail near base is 16 mm. including fins.

The webbing on foot includes the first (proximal) phalanx of each toe, the toes terminating in points; a small inner metatarsal tubercle, the outer if present is not discernible; a small inner metacarpal tubercle; hand with the web extending slightly farther than on toes; the pits on the dorsal, lateral, and ventral part of head are con- spicuous, giving the head a corrugated appearance in the occipital

fold; distance between eyes (13.5 mm.) greater than distance be- tween nostrils (11.2 mm.); depth of head (25 mm.) more than half the length of head (from tip of snout to the base of last gill, 44 mm.) ; large pits on head, about eyes, the angles of the jaws, and to a lesser extent on snout, discernible but not conspicuous; dorsal, lateral, and ventral sides of the body, and sides of tail granular; the summit of each granule with a minute pit.

Dorsal fin arising on the back part of head, continuing as a low, somewhat thickened fold along the back, rising to a height of six millimeters between hind legs, and on tail to a maximum of about ten millimeters; cloacal region (male) greatly swollen, the walls thickened and heavily papillate; adpressed leg reaches the elbow of the adpressed arm; fingers flattened, terminating in points; a slight web is evident between the distal ends of the metacarpals and meta- tarsals, and sometimes suggesting a slight fringe along the side of digit (if the digits are slightly dessicated) ; an inner and an outer metacarpal tubercle; similar metatarsal tubercles; the edge of the opercular fold is free for 15 millimeters on the median ventral line; eleven costal folds (12 grooves), between axilla and groin.

Maxillary and premaxillary teeth about 60-60; vomero-palatine tooth series practically continuous (12-36; 12-33), slightly diagonal, arching anteriorly, but separated medially by a distance less than one-sixth the distance between the choanae; mandibular teeth about 60-60; splenial teeth about 16-16 with a rather large hiatus in the middle of the series.

Color in life. Deep purplish-black. The summit of the granules light; the corners of the mouth, and the tips of the digits lighter.

Variation. The measurements given above show age and sex variation. The smaller paratypes are more or less lavender above and often somewhat creamy lavender below. The lateral line organs may have lighter spots about them, and the throats may be dirty cream. In some of the smaller specimens the teeth may be some- what irregular and the splenial series may not have penetrated the gums. In the old, neotenic specimens most of the splenial teeth have been shed. No trace of them is present in the transformed specimens.

Remarks. The larvae of this form differs from Siredon dumerelii Dugés in having a much narrower, less flattened head, a more rounded snout, a deeper, more robust tail, a laterally, compressed body; the gular fold free for a greater distance on median ventral line, the pitting on the head less conspicuous; the body more robust;

430 Tue UNIversiry SCIENCE BULLETIN

no break (or a very slight one) in the continuity of the vomero- palatine tooth series, while the combined series is separated medially by a wider distance. The color is very dark, almost black.

From Siredon mexicana (Shaw), the species differs in having a more robust, mere laterally compressed body and tail; in having the dorsal fin originating farther forward on head (in mexicana be- hind level of insertion of arms), in the lack of spotting on body, and in a smaller series of splenial teeth.

It is significant that these forms are each in a different drainage system. S. mexicana is connected with the Rio Panuco system to the Gulf of Mexico (formerly underground drainage?) ; S. dumerilit with the Cuitzeo-Patzcuaro system (underground); Siredon ler- maensis with the Rio Lerma-Rio Santiago system to the Pacific.

This species is used for food. It is regularly offered for sale in the markets of Toluca and perhaps elsewhere during the fishing season.

Mexican Snakes of the Genus Typhlops

EDWARD H. TAYLOR, Department of Zodlogy, University of Kansas

Apsrracr: There are three well-known representatives of the genus T'yphlops in Mexico. All are known from definite localities; all are known from more than a single specimen; and all have been found by at least two different col- lectors. These are Typhlops basimaculatus Cope; T. braminus Daudin, and T. microstomus Cope. A fourth species, Typhlops psittacus Werner, described from a single specimen, the collector unknown (or at least not stated), and with no more definite locality data than “Mexico,” belongs to a section of the genus having a sharp transverse edge on the snout, a section of the genus hitherto unknown from the western hemisphere. In consequence one is rather prone to question the label.

Typhlops basimaculatus Cope

Typhlops basimaculatus Cope, Proc. Acad. Nat. Sci. Philadelphia, 1866, p. 320. Type locality, “Cordova and Orizaba”’ Veracruz.

Cope described this form briefly from a specimen or specimens sent from Mexico by Sumichrast. Three years later Peters described a form Typhlops perditus. (Monatsb. Akad. Wiss. Berlin, 1869, pp. 480-436. Type locality, Orizaba.) Since he compares the form with Typhlops reticulatus I suspect that he had not seen Cope’s description from which his own does not differ in any significant character. At a much later date F. Miller described a form which he designated Typhlops (praelongus n. sp.?) (sic) from Cordoba. He compares it with Peters’ perditus, stating that it “steht dem T. perditus Peters sehr nahe, und unterscheidet sich von ihm wesent- lich nur durch jede Abwesenheit einer Spur von Auge.” Boulenger (Catalogue of the Snakes in the British Museum, 2d Ed. I, 1893, p. 28, and Gunther (Biologia, Centrali Americana, Batrachia and Reptilia, April 1898, p. 86) refers the three above species to Typh- lops tenuis Salvin (Proce. Zool. Soc. London, 1860, p. 454. Type

(441)

442 THe University ScreNcE BULLETIN

locality Coban, Guatemala). This latter species is described by Salvin as having 17 scale rows and no mention is made of the yellow head and yellow tail tip.

Bocourt (Mission Scientifique au Mexique; Etudes sur les Rep- tiles, Livr. 8, 1882, p. 499) describes and figures a form from Guatemala* which he identifies as Typhlops perditus Peters and which is figured as having a well-developed eye.

Thus we have a vellow-headed form in Guatemala having similar body proportions to the form described by Salvin; 18 scale rows are present about the body, as is hkewise true of perditus, basi-

maculatus and praelongis.

Fic. 1. Typhlops basimaculatus Cope. EHT-HMS, No. 5499; Potrero Viejo, Veracruz, Mexico. 5.

While the above facts point to a possibility of a close relationship to Typhlops tenuis 1 doubt the matter is settled beyond question. In consequence I am maintaining Cope’s name, knowing that it is certainly applicable to this form, and trusting that the future will offer an opportunity for the examination of the type of T. tenuis.

A specimen in the EHT-HMS collection No. 5499, presented to me by Mr. Dyfrig McH. Forbes, was collected at Potrero Viejo some ten miles east of Cérdoba, Veracruz. It presents the following characters: Head much flattened, the thickness at anterior edge of mouth only one-half the width of head; the greatest depth of head is three-fourths the width of head; nasal completely divided, the suture arising from the first labial; four upper labials; posterior nasals not in contact behind the rostral; latter rather tongueshaped, about a fourth wider, on upper surface, than on ventral surface, not reaching posteriorly to the level of the eye; preocular large, dis- tinctly wider than the ocular, and of slightly greater area; ocular

*He states ‘““Mexique, Guatemala’ for the source of the specimen figured; measurements lrom a4 Guatemala specimen are given.

Taytor: MeExICAN SNAKES 445

somewhat longer vertically than the preocular; no subocular; scales following rostral a little larger than body scales; supraoculars about same size as the scale following rostral; two elongated parietal scales on each side (the anterior broken on the left side) ; anterior parietal separated from the last (fourth) labial by two scales, which, with the parietal and labial form the posterior border of the ocular; men- tal very small; three lower labials; eye represented by a small pig- mented area. Seales in 18 rows throughout body. The nine ventral rows are immaculate; the dorsal rows are spotted, each spot cover- ing (usually) parts of four scales; the yellowish reticulation between the spots not confined to the scale edges; dorsal part of snout, and sides of head to behind ocular, immaculate yellow-white; scales from rostral to tip of tail, 391; ten scales under tail.

Total length, 248 mm.; diameter of body, 4mm.; width of head, 4mm.; depth of head in front of mouth, 2mm.; at eyes, 3.2 mm.; diameter of body in total length, 62.

I have compared this specimen with the type (U.S. N. M. 6602, Cérdova, and Orizaba, Veracruz, F. Sumichrast), and find no signifi- cant differences. The type is more robust. The head examined un- der a strong lens shows searcely a trace of the eye; the snout is : very blunt oval, nearly truncate. There are actually three lower labials. Color faded, but the pigment pattern on head is very simi- lar to the described specimen; eight dorsal scales pigmented; re- maining ten rows whitish; 385 scales, mouth to anus; 9 scales under tail; total length (about) 330 mm.; tail, 42mm.; head width, 4.8 mm.; greatest body width, 6mm.

Typhlops microstomus Cope

Typhlops microstomus Cope, Proc. Acad. Nat. Sci. Philadelphia, 1866, p. 125. Type locality, Yucatan, Mexico.

This species is widely separated from other described species 1 America by the following combination of characters: eighteen scale rows; one preocular; one subocular separating the ocular from labial; eve, on ocular-preocular suture, scarcely visible; lower Jaw narrowed at tip; snout rounded, not hooked. ‘Color yellowish-olive, becoming brighter yellow posteriorly.” Specimens, other than the type, are known.

Typhlops psittacus Werner

Typhlops psittacus Werner, Zoodl. Anz. XXVI, No. 693, Feb. 9, 1903, p. 248. Type locality, “Mexico.”

This form is distinguishable from other Mexican forms in having a hooked snout with sharp side margins; the nostril on the under-

444 THe UNIversiry ScreENcE BULLETIN

side of snout, a subocular present. The description gives 24 as the number of scale rows, while the key included in the description gives 20 rows for the species. So far as I can learn this species is known only from the type. As all forms known having a sharp snout are old world forms, one might be tempted to question the “Mexico” locality label.

Typhlops braminus (Daudin)

Eryx braminus Daudin, Histoire Naturelle Générale at Particuliiire des Reptiles, vol. VII (year XI) 1808, pp. 279-280.

Specimens of this species have been taken in southern Guerrero, in the general region near Acapulco. It is likely that it was im- ported from the Philippines. Peropus mutilatus and Hemidactylus frenatus, two other Philippine reptiles, have reached the west coast of Mexico.

Fic. 2. Typhlops braminus Daudin. EHT-HMS, No. 5251; two miles south Garrapatas, Guerrero, Mexico, June 27, 19382. 5.

The EHT-HMS collection contains the following specimens of the species: No. 5251, two miles south Garrapatas, Guerrero; elevation, 590 m.; collected by Hobart M. Smith, June 27, 1932. No. 15917, Agua del Obispo, Guerrero, June 25, 1938; No. 15918, at km. 388 near Xaltinanguis, Guerrero; Nos. 15919-15933, El Limoncito, Guer- rero, about 15 km. north of Acapulco, all collected by E. H. Taylor.

All of the localities listed are less than fifty miles from Acapulco which, I suspect, was the port of entry of the species into Mexico.* The extent that it has spread suggests that the importation is not particularly recent, but probably dates to the time when the Spanish galleons carried trade between Acapulco and the Philippines.

*Since the above was written, notice of the discovery of this species in Mexico has ap- peared in Herpetologia, I, No. 5, p. 44. The locality, Chilpancingo, is approximately 80 miles from the coast.

Lacking a specific locality for Plastoseryx bronni Jan, the associ- ation of this species with bicolor is largely a guess. Bocourt, on the basis of the figure of Jan & Sordelli (loc. cit.), retains the species as distinct. The coloration agrees with that of Loxocemus bicolor

Cope. The differences in squamation may be due to anomaly.

Two specimens of Loxocemus bicolor, a large female and a young female are in the collection (EHT-HMS Nos. 5500 near Puente de Ixtla, Morelos, km. 97.5, and 5501 Agua Bendita, Guerrero km. 185.5). These specimens have the dorsal, purple-lavender coloration clearly set off from the ventral coloration of creamy white. A slight pigmentation occurs on the inner edges of the subcaudals. These present the following scale data: Ventrals, 242, 242; subcaudals, 46,46; seale formula, 45-34-34-34-26, 44-33-33-32-26; upper labials, 9-10, 9-10; labials enter eye, 4-4, 5-0; lower labials, 13-12, 13-12; preoculars, 1-1, 1-2 (the lower on left side minute, separating fourth labial from eye); postoeulars and suboculars 4-4, 4-3; temporals ay ikea Bei (oreinG: luego sie slang

While it is not certain that these characters will prove constant when larger series are available, these differences obtain in my specimens of bicolor and swmichrasti, respectively. Anterior chin- shields are proportionally much larger while the scale adjoining outer seale is distinctly shorter than the first chinshields; in swmi- chrasti the outer scales bordering the chinshields are longer than the chinshields themselves; the first pair of lower labials are longer than in bicolor. The suture between the internasals is equally as long as that between the prefrontals in bicolor; in swmichrasti the prefrontal suture is one and one-half times as long as the internasal suture; rostral ridge higher in bicolor.

The ventrals and subeaudals of swmichrasti are 300, 309; of

This species described by Bocourt in 1876 was not regarded as distinct when he treated of the genus in 1882. Sumichrast, in 1880 loc. cit., discussed the species, and pointed out that specimens col-

448 Tue UNIversITy SCIENCE BULLETIN

lected in the western part of the Isthmus of Tehuantepec showed marked sexual variation in color (from pure white to “gris cendre’’) and mentions that specimens from his collections sent to the Smith- sonian Institution were referred by Cope to Loxocemus bicolor.

It appears from material in recent collections that the two forms are distinct, and the color variation is actually specific, rather than due to sexual or age differences.

Two specimens were captured from a pile of rocks near the edge of a tiny lake near El Limoncito, Guerrero, in 1938. Both are young specimens and have a heavily pigmented venter, the heads being very dark purple. These correspond in the characters of coloration reported by Taylor and Smith, loc. cit., for a young speci- men likewise from Guerrero. Oliver, loc. cit., records a female specimen from Colima having the ventral scales “closely stippled with brown at base.”

Two specimens now in the EHT-HMS collection have the follow- ing scale characteristics. Nos. 4574, 5502; yg, yg. Scale formula, 44-36-34-34-28-26, 44-34-32-32-28-26; ventrals, 256, 265; sub- ‘audals, 44, 44; (according to Bocourt the types have 252 to 265; subeaudals 42 to 45). Preoculars, 1-1, 1-1; postoculars 3-3, 4-4, the upper part of the fifth labial is segmented on each side forming a (subocular) preocular. Labials enter eye, 4 and 5-4 and 5, 4-4; upper labials, 11-11, 11-10; lower labials, 13-14, 13-13; temporals 3+6+6,3+5-+6; seales between chinshields and first ventral, 13, 10.

This specimen figured is as long as the figured specimen of bicolor, but the head and the body are much more slender.

Natrix valida (Kennicott) (Figure 3)

A small specimen, far out of the known range of the species, was collected at a small lake near El Limoncito, about 12 km. north of Acapulco, Guerrero, July 3, 1988 (EHT-HMS. 19224). It differs somewhat from the typical Natrix valida in having only a single series of well-defined lateral spots, instead of two; a wholly un- divided nasal, a lower number of ventrals; nine instead of ten lower labials. The following characters obtain:

Rostral slightly visible above; internasals longer than wide, nar- rowed greatly anteriorly, as long or longer than the prefrontals; latter scales very much wider than long, strongly bent down over side of snout; anterior margin of frontal nearly transverse, the sides minutely concave, the widest point of scale near the posterior

equal in length, the posterior wider, curving on inner edges, sepa- rated by one scale anteriorly, three posteriorly; lower labials 9-9, four touch first chinshields; diameter of eye equal to its distance from nostril; 26 scales across back of head; scale formula, 21, 21, 19; ventrals, 183; subeaudals, 72; anal divided; six scales between the third ventral and the last lower labial.

Color. Variable grayish olive-brown above and on sides; a row of small dark spots on the fourth scale row, the spots encroaching somewhat on adjoining row, each spot separated by width of about one scale; the next three outer scale rows lighter, but the upper edge of outer scale row with a fairly continuous dim brownish line; on median scale row a hair-fine whitish line present; on each side of

Total length, 181 mm.; tail, 45 mm. While this very young specimen may represent a separable form, it seems unwise to recognize it until other specimens are available. Colima is the nearest point where the species has been recorded.

Ninia sebae sebae (Duméril and Bibron) Streptophoris sebae Duméril and Bibron, Erp. Gén., 7, 1854, pp. 515-517.

In the collection are EHT-HMS Nos. 5210-5215, 15949-15960 ob- tained at Cuautlapa, near Orizaba, Veracruz, Taylor collector; Nos. 5216, 15961-15966, Potrero Viejo, Veracruz, Dyfrig Mc. H. Forbes, collector; No. 5217, locality uncertain, but thought to be from near base of Mt. Popocatepetl, Puebla, John Rickards, collector; No. 15967 near Fortin, Veracruz, Taylor collector.

Eight of the specimens show an equal distribution of the black pigment spots over the apices of dorsal scales; eighteen specimens have a double series of small black spots on the back, usually more or less regularly distributed; there are from 17 to 25 pairs which may tend to alternate in some places. One of the specimens has the spots sparse and in a single, irregular, median row (No. 15949). One specimen has the spots arranged in narrow continuous (or broken occasionally) bands across body. ‘These reach first scale row; about 26 on body, 11 on tail (No. 5217).

The type locality “Mexico” has been recently restricted by Karl P. Schmidt, to Veracruz. The variation in the ventrals is given by Duméril and Bibron, 131-138 ventrals; 44-56 subcaudals. Since these counts fit into similar series made from specimens from a single locality (with one exception), there can be no significance in the differences in the range (the exception being 131, which is lower than my lowest count of 135, a male from Cuautlapa).

The scale data taken from the above series is as follows. Males (18), 135-145 ventrals, average 141; 52-59 subcaudals, average 55. Females (11) 139-148 ventrals, average about 142; subcaudals 44-52, an average of 48. Thus in these short snakes there is a broad over- lap in the ventral counts in the two sexes; in the subcaudals there ap- pears to be a sexual differentiation; the highest subcaudal count of a female specimen is equal to the lowest count for a male. There is, however, an average’ difference between the sexes of one scale in the ventral series and a difference of seven in the subcaudals.

TAYLOR: SOME MEXICAN SERPENTS 451

Schmidt (Zo6l. Ser. Field Mus. Nat. Hist., XX, No. 18, October 31, 1936, Notes on Snakes from Yucatan) separates the Yucatecan form as Ninia sebae morleyi. The ventral average of the males is about 143, with a range from 141-147; an average of two higher than males of the typical form; the subcaudal average is 49, with a range from 44-54. This is an average difference of seven scales from the typical form. The ventral average for female specimens is about 147, a range from 145-152. This is five scales higher than females of N. sebae sebae; the subcaudals average about 43, with a range of 36-46. This average is five scales lower than the speci- mens In my series.

The scale formula is 23-19 about back of head; on body, 19-19- 19. The neck count on one specimen was 17, on another 21. All others 19; the preanal count occasionally became 18, due to the dropping of the middle row (4 cases).

In only one case were there but six upper labials, this due to obvious fusing of the sixth and seventh. In one case only were there but six infralabials, due to an obvious fusion of the fifth and sixth. Five specimens had single preoculars, usually resulting from the segmentation of the upper part of third labial, and in some cases excluding the third labial from eye. Three others had preoculars on one side only, and one had two preoculars on one side and one on the other. They were wanting in all other specimens. Only one specimen had three postoculars. In all other specimens two were present. In all cases four lower labials touched the anterior chin- shields which in two cases were no longer than the posterior pair.

Seven of the specimens were above 300 mm. in length. The larg- est is No. 5217, and measures 321 mm.; No. 15966 measures 320 mm.

Males have asperities on the mental, first pair of labials, and first pair of chinshields. These are not or barely indicated in females.

Ninia diademata Baird and Girard

Four specimens were captured at Cuautlapa (Tlilapan) near Orizaba, Veracruz, in 1938 (KHT-HMS Nos. 5581-5584). These have the following scale counts, respectively: ¢ 148-83 = 231, g 145-90 = 235, 9 148-85 = 233, g 148-96 =139. The scale for- mulae are normally 21-19-19-19. In one, the scales number 24 about the head, and one has a count of 17 in front of anus. In the largest male, No. 5584, the mental, first pair of lower labials, and the first pair of chinshields have rather prominent asperities; these are less distinct in the smaller male. All scales are strongly keeled and

longitudinally striated, the striations extending onto the outer edges of the ventrals.

Geophis semidoliatus (Duméril and Bibron)

Geophis semidoliatus Taylor and Smith, Univ. Kansas Sci. Bull., XXV, 1988 (1939), pp 244-245.

A large series of this species (HEHT-HMS Nos. 16010-16140) was obtained near Cauautlapa (Tlilapam, Qualquapan) in 1938. Scale counts were made on 96 specimens—49 males and 47 females—and the results are as follows: The ventrals on females vary between 155 and 170 (16 scales), while in the males they vary between 137 and 143 (7 scales). The subcaudal scale counts vary, in females, from 20 to 27 (8 seales), and in males from 22 to 30 (9 scales). The range of the total count (ventral and subeaudals) in females is from 176 to 195 (20 seales); only a single specimen exceeded 188; in males the variation is between 160 and 173 (14 scales).

Thus the known maximum for ventrals of 195, and the known minimum of 160 was reached in a series taken in the same identical locality.

In this series the supraoculars, preocular, postocular, temporal, and anal are invariable. The scale formula 15-15-15 is very stable. One specimen has 14 scale rows on neck, and one had 14 in front of anus; one specimen had the formula 13-15-15-13. A pair of fused labials accounted for the count of five labials on one side in two specimens, instead of six.

I suspect that the species has a limited distribution. It is known only from central Veracruz.

Geophis blanchardi Taylor and Smith

Geophis blanchardi Taylor and Smith, Univ. Kansas Sci. Bull., XXV, June 1, 1838 (1939), pp. 245-247, fig. 2 (type description; type locality, two miles southwest Acultzingo, Veracruz).

Data taken on five topotypic paratypes of Geophis blanchardi (EHT-MHS Nos. 5479-5483) were omitted from the type descrip- tion. I take this occasion to comment on these specimens.

The dark marking shown on the head of the type is not due, as suggested, loc. cit., to shed scales. The frontal and parietal scales are normally darker than the remainder of the dorsal head scales. In all the specimens, save type, the outer edge of the parietal is not as dark as the remainder of the scale. Two of the specimens are grayish-blue above, more or less iridescent; the other three are darker, more or less bluish-black to blackish, and likewise iridescent. In all the specimens the ventral markings are as depicted for the type. The lower labials are as heavily pigmented as the upper

labials save that in two of the specimens there is an ill-defined light spot on the labial border below the eye as in the type.

The following ventral and subcaudal scale counts obtain. The ventrals are counted to the last chinshields.

In No. 5479 the 4th to 11th subcaudals are single; in all, the anal is single, and the head scales are as in type unless otherwise mentioned; in all, the scale formula is 17-17-17.

Enulius unicolor (Fischer) Enulius unicolor Taylor and Smith, Univ. Kansas Sci. Bull., XXV, 1938 (1939), p. 247.

Eight specimens of this species were taken by me in 1938 as follows: EHT-HMS No. 5572, Agua del Obispo, Guerrero, July 6. Nos. 5573-5578 near Huajintlan, Morelos (km. 1383) July and Au- gust; No. 5579 between Zitacuaro and the Rio Tuxpan, Michoacan. This latter specimen extends the range very considerably to the northwest. Despite the wide range, the characters are relatively constant.

There is no trace of a light collar in any of these specimens; the frontal is longer than its distance from the end of the snout. There is some variation in the lower labials, there being three or four labials touching the large anterior chinshields. Younger specimens are olive above, while the older specimens are light brown on all except outer scale row, which is creamy white. The ventral colora- tion is creamy white.

A series of specimens (EHT-HMS Nos. 15331-15342) were ob- tained from San Cristobal, Chiapas, collected by Henry Thomas. T collected a single specimen (KHT-HMS No. 4561) near Ocozu- coautla, Chiapas, September 3, 1935, from under a rock near a small waterfall. The first group of specimens show the following ventral, subeaudal and total scale counts (the ventrals are counted to the second pair of chinshields; these anterior scales are not widened, but are single, median scales; there are usually two or three between the first widened ventral and the small second chinshields): 9? 138-23 = 161; g 128-36—=164; g 126-31=—157; 9 136-27=163; 9 1380-24— 154; g 127-34=161; 9 1382-25157; ¢ 128-37=165; 9 138-25= 163; g 128-32=160; 9 135-24=159; 3g 123-33=156.

The general coloration above is dark or light brown with some indication of a darker medial line or sometimes with narrow lines on the sixth scale rows. In others there is little variation evident in the dorsal coloration. The lateral stripe, occupying most of the space on the third row and adjacent parts of the second and fourth rows, is, in some specimens, of a nearly uniform color. In others, the scales show lighter centers. The outer scale row may be almost entirely cream; or with the edges of each scale nearly surrounded by black; or the dark color may form a series of small spots on the outer row. Some have a row of tiny dots on the outer edge of each ventral.

Two of the specimens have large, deep black, triangular spots medially on the ventrals beginning at about the first widened ven- tral and continuing to vent and forming a continuous line. A dark median line is present under the tails of all the specimens; three other specimens have these median ventral dark spots faintly indi- cated; in the others the entire ventral surface of body is cream; head entirely dark above, the chin and upper and lower labials, creamy- yellow. In some specimens one upper labial (or more) may have its upper edge dark. In life the specimens are strongly iridescent.

In the character of the head scales there is slight variation. The

TayLtor: SoMeE MEXICAN SERPENTS 455

upper and lower labials are 7-7; the scale formula, 17-15-15-15; two postoculars; one loreal; no preocular; third and fourth labials en- tering eye. One specimen only has the loreal segmented leaving a small preocular; one specimen has the second labial segmented mak- ing eight supralabials on one side. Another has eight lower labials on both sides.

One specimen, No. 4561, has the chinshields bordering the lip, there being two labials anterior, and four labials posterior to the chinshield; on one side the two temporals are fused making a single long temporal.

The resemblance of the generic characteristics of the genus Adel- phicos is strikingly similar to those of Oxyrhabdium from the Philippines.

Diadophis regalis dougesu (Villada)

Diadophis regalis dougesii Taylor and Smith, Univ. Kansas Sci. Bull., XXV, 1938 (1939), pp. 240-241, fig. 1.

Two specimens, EHT-HMS Nos. 5555 and 15869, the first from near Tulancingo, Hidalgo, the second from 15 kilometers west of Morelia, Michoacan. The ventral and subcaudal counts are re- spectively, ¢ 185-61—246, g 193-61—254; upper labials, 8-8, 7-8; lower labials, 8-9, 9-8; scale formula, 23-17-17-15, 22-17-17-15; width of nuchal yellow band, 2% scales, 2 scales. The specimen from Michoacan is the darker, now almost black (having been pre- served in formalin) ; the specimen from Hidalgo is olive-gray-brown generally.

Conopsis frontalis (Cope)

Conopsis frontalis Taylor and Smith, Univ. Kansas Sci. Bull, 1938 (1939) p. 241, pl. XXIII, fig. 3.

I collected two specimens of this species in 1938 (EHT-HMS Nos. 5497-5498) near Huajintl4n, Morelos (km. 133). These two differ from each other in the general color pattern. No. 5498 has a series of 40 dark, median, dorsal spots from neck to anus (tail broken), sepa- rated by a cream spot a little longer than a single scale, and about two scales wide. The dark spots are three to four scales long and four or five scales wide. On each side of these spots, after an in- terval of about one scale, is a row of somewhat elongated small spots which form a broken line on the third and fourth scale rows; this connects with the darker edges of the adjoining scale rows. The whole pattern suggests that the typical saddlelike blotches shown in the figure (Taylor and Smith loc. cit.) were broken later- ally throughout the length of body and tail.

456 Tue UNIVERSITY SCIENCE BULLETIN

The general ground color is smoky lavender. A more or less regular series of dark flecks on the alternate scales of the outer row, may extend onto the ventrals. Ventral coloration is somewhat pinkish white. The head markings are very similar to those of the figure.

No. 5497 differs markedly. The dorsal spots are not well differ- entiated, but careful observation shows a transverse blotch outlined by the darker edges on scales, the outlines separated by a tiny white spot, medially. The scales all have light centers with dark edges, or one-half of the scales may be dark. The ventral coloration is ivory-white with the dark spots on the outer scale row encroaching on the ventrals.

Both specimens are males, the ventral-subcaudal count is: No. 5497, 155-44; in 5498, 157-25. Scale formula in both: 24, 17, 17, 17. The specimens agree with Michoacan specimens in practically all other character. No. 5497 has a large loreal segmented from the side of the prefrontal on one side.

Eudryas boddaerti mexicanus Stuart, Occ. Papers Mus. Zodl. Univ. Michigan, No. 254, February 9, 1933, pp. 8-9. (Type description; type locality ‘‘Zacuapan,” Mexico).

Three specimens of this rare snake are in the collection from Potrero Viejo, Veracruz: EHT-HMS. Nos. 5256A, 5598, collected by E. H. Taylor; No. 5599 by Dyfrig McH. Forbes. As the form has previously been known only from type I include a description and figure.

Color in life. Above, nearly uniform light olive, generally yellow- ish below; labials yellowish-cream with a dark brown to blackish line from eye along their upper borders; a few black flecks on lower edge of upper labials. Chin and lower labials grayish with enclosed cream spots on all the scales; a series of dim cream transverse bands, the first forming a median angle, visible for about one-third the length of the body.

Since preservation, the color has become dark olive-brown above, the lighter color of the ventral surface has become clouded; the upper labials have become much darkened.

Variation. No. 5999 has been preserved in formalin and the color has become dark brownish (blue where the epidermis has shed). The markings under the chin are scarcely discernible and the venter is clouded ultramarine. A young specimen, No. 5256, is very light

Where epi- dermis is shed the color is ultramarine-gray. The scale count of the two above specimens are respectively: Ventrals, 177, 174; sub- caudals, 109, 128. The scale formula of both is 24-19-17-17-15-15. No. 5599 is 1163 mm. in length; the tail, 345 mm.

Dryadophis sleveni Stuart

Eudryas sleveni Stuart, Occ. Papers Mus. Zo6l. Univ. Michigan No. 254, February 9, 1933, pp. 9-10. (Type description; type locality, Maria Madre Island, Tres Marias Islands. Mexico.)

A specimen captured four miles north of Acapulco, Guerrero, is tentatively referred to this species. The head squamation appears to be rather close to sleveni; the ventral count is only two more, the subcaudal count only four more, than recorded for slevent.

The specimen is a juvenile with an elaborate pattern which has not been recorded for slevent. However, it may occur in the young.

The specimen is generally brownish-olive with a series of narrow, transverse, brownish-white bars which cross the back, connecting with dim light lines running the length of body on the fourth and fifth scale rows (posteriorly on fourth). This leaves a series of 71 quadrangular spots on the back of body, slightly edged with black anteriorly and posteriorly; the pattern is continued on the tail. The coloration below the lateral light line is variegated darker and lighter, but appearing rather uniform on the whole, save for a sug- gestion of lighter lineation on first and second scale rows; below, the color is yellowish-white, while the chin and lower labials are mottled with cream spots surrounded by darker grayish markings; this color- ation continues on the first ten ventrals; whitish on underside of tail with minute blackish flecks along the inner edges of the scales. Scale formula, 24-17-17-15-15. Ventrals, 195; subcaudals, 115.

A specimen in the collection (EHT-HMS No. 5496) was collected by Dyfrig McH. Forbes and presented to me.

It presents the following scale characters: Ventrals, 214; sub- caudals, 123; anal single; upper labials, 7-8 (abnormal on both sides) third and fourth (fourth and fifth) entering eye; lower labials, 8-9; four touch the first chinshields, which are somewhat shorter than second pair; latter separated by a row of scales; scale

ocular is in contact with the frontal; the prefrontals are a little wider than long; the frontal is slightly narrowed medially, longer than wide and its length greater than its distance from the end of the snout; the sixth labial is low, touching only two temporals.

The specimen presents the following data: Ventrals, 262; sub- caudals, 115; scale formula, 36, 31, 33, 26, 22; 57 spots on body; 35 on tail; 8-8 upper labials; 11-11 lower labials; preocular, 1-1; postoculars 2-2; temporals, 3 + 4-++ 5; loreal elongate, nearly twice as long as high. Nasal constricted, the anterior moiety much higher than posterior; scales of head, including temporals, minutely rugose, save that the rugosities are present only on the sides of the frontal and the outer edges of the parietals.

The ground color is faun, each scale having a slightly darker center and two cream spots at its base. The body has 57 quadran- gular dark-brown spots; the tail has 35, which are somewhat darker on the edges, each scale with a slightly lighter center. A lateral series of spots alternating with the dorsal blotches and still lower on side there is a series of smaller dots alternating with the lateral spots. On the edges of the ventrals and extending onto the first scale row is another series of tiny blotches which are separated from each other by cream spots; posteriorly the dark dots are almost continuous and the cream spots are more conspicuous. The median part of the ventral scales lack spots but the posterior edges of the scales are of a very slightly darker shade than the remainder. The head markings are depicted in the figure. Length total, 486 mm.; tail, 104 mm.

Elaphe laeta (Baird and Girard)

Elaphe laeta Dunkle and Smith, Occ. Papers Mus. Zoél., Univ. Michigan, No. 363, Dec. 16, 1937, p:. 6.

I collected a specimen of this form (EHT-HMS, No. 5372) about 30 km. south of Laredo in Nuevo Leon, in 1936. It agrees well with specimens in this collection (Nos. 4683-4684) collected and studied by Dunkle and Smith. Ventrals vary between 217-224 (the ventral count for No. 4683 is 217 instead of 205). In all, the alternating bands of dark and light loop across the head; the median scale series on the posterior part of the body are more or less keeled; and the ventrals are marked with numerous small quadrangular dark spots, which blend to form an uninterrupted row on the subcaudals.

A second specimen (No. 5552), taken 4 km. north of Villagran Tamaulipas, a younger female specimen, has 234 ventrals—the tail lacking the distal part.

TayLorR: SoME MeExIcan SERPENTS 461

There are 41 spots on the body and 16 + on the tail. The quad- rangular spots on the venter tend to segregate and make irregular dark bars on the venter, separated by two or three unspotted ven- trals. Temporals, 3-++ 3-+ 5 on right side, irregular on left; upper labials, 8-8; lower labials, 13-13; scale formula, 36, 25, 27, 27, 22.

Elaphe chlorosoma (Ginther)

Coluber chlorosoma Giinther, Biologia Centrali-Americana, 1894, p. 115, pl. XLI (type description; type locality, “‘Atoyac, Guerrero, Amula, Guerrero, San Ramon, Jalisco, 1,500 feet’’).

Three specimens are in the collection (EHT-HMS, Nos. 5190- 5192). The first two numbers are from El Sabino, Uruapan, Micho- acan; No. 5192 is from near Chapala, Jalisco. They agree with the type description in most characters. The specimens are of a bluish- gray color. Each scale has a very tiny dark mark at the base with a tiny white spot on each side of the scale just in advance of the darker area. Light edges on ventrals form a more or less continuous, narrow, light line on the ventrolateral region. The outer parts of the ventrals are gray save for the light edge, while the major, medial part of each ventral is immaculate cream. Chin and labials cream, save that the upper edge of the anterior labials are gray and the last labial is entirely gray.

These specimens have the following characters, respectively: No. 9190 g¢ , 5191 g , 5192 9 ; ventrals, 260, 262, 267; subcaudals, 118, 120, 93; upper labials, 8-8, 8-8, 9-9; lower labials, 9-9, 10-10, 10-10; preoculars, 1-1, 1-1, 1-1; postoculars, 2-2, 2-2, 2-2; the preocular is separated from the frontal in all. The temporals are somewhat irregular, but three is the normal number of anterior temporals.

Elaphe flavirufus (Cope) (Figure 6)

Coluber flavirufus Cope, Proc. Acad. Nat. Sci. Philadelphia, 1866, p. 319 (type description, type locality, Yucatan).

This species has remained rather rare in collections. I obtained a single specimen (EHT-HMS, No. 5373) crawling across the high- way at night at km. 615 north of Mexico on the Laredo-Mexico City highway about midway between El Limon and Llera.

Cope’s type was a young specimen with a yellow ground color, un- spotted below; above, with spots on back brick red, broadly brown margined. One foot 10 inches in length.

462 Tue UNIVERSITY SCIENCE BULLETIN

The present specimen is adult, the general ground color faun, with 34 large, brownish, black-edged, dorsal blotches partly broken and occasionally confluent; alternating with these are 35 smaller lateral blotches, of similar color, each longer than high, reaching first scale row or ventral edge. On edges of the ventrals a series of small spots sometimes opposite sometimes alternating with the lateral spots. The character of the head markings is shown in the figure given.

Salvadora mexicana Bogert, Pub. Univ. California at Los Angeles in Biol. Sci., I, No. 10, pp. 184-186.

I obtained four specimens of this species in Guerrero and Southern Morelos in 1938, as follows: EHT-HMS Nos. 5587 near El Li- moncito, 15 km. N. Acapulco, June 26; 5588, near Totolapam, Guerrero, June 6; 5589, 5590 Huajintlan, Morelos (km. 133), July 7.

No. 5587 had partially swallowed a large Sceloporis melanorhinus, and No. 5588 had eaten a Cnemidophorus sp. which it was made to disgorge. All the specimens are adult. The ventral-subcaudal count (in the order given above) is as follows: 189-125, ¢ ; 187- dee. 190-132, 45 187-137," ¢.-

These counts, together with those given by Smith (loc. cit.), show a slightly higher average of caudal scales for specimens from Guer- rero and Morelos as compared with those from Colima and Michoa- eAn (134-127.5). There is a difference of only one scale in the aver- age of ventrals.

The total ventral-subeaudal counts show the following small dif- ferences: The average for Michoacan and Colima specimens is 215.6; the average for Guerrero and Morelos specimens 220.9. The males and females cannot be separated on the basis of the counts alone, males sometimes exceeding the female ventral count, and females equaling the male subcaudal count.

464 THE UNIversiITy ScrENCE BULLETIN

Cumbres (Tres Marias) near the summit of the range between Mexico City and Cuernavaca at an elevation between 9,000-10,000 feet. The first two specimens, both young, have been crushed by automobiles. The third specimen presents the following characters:

Rostral narrowly visible above; nasal divided; loreal longer than high; one preocular; two postoculars; upper labials, 9-9, the fourth, fifth and sixth border orbit (on left side the fourth only and a large subocular, the latter apparently segmented from the fifth or sixth labial); 12-12 lower labials, 4-5 touching the first pair of chinshields which are larger than second pair; latter widely sep- arated by two or three scale rows (on the left side one is broken in two) ; only one pair of prefrontals. Scale formula, 35, 27, 27, 25, 21; ventrals, 238; subcaudals, 65; anal single.

Head light brown above, yellow below; two longitudinal black lines separated by 31% scale rows, begin on neck and continue back about one-fifth the length of body; here they break up into paired, elongated spots which become larger farther back, and unite to form still larger black spots with brown centers; toward the posterior part of the body, the spots are smaller, blacker and the centers of only a few scales of the spots have brown centers; twelve spots on tail. Anteriorly the venter is immaculate yellow-cream with brown- ish marks on the ends of ventrals; farther back blackish spots ap- pear near the middle of the ventrals growing more numerous under tail.

I obtained an adult specimen of this rare snake (apparently known heretofore only from type) about 15 km. east of Morelia, Michoacan, in 19388 (EHT-HMS No. 5511).

The specimen agrees with the type in most details of color and markings. The head is black as far back as the posterior fifth of the parietals where the color forms a very broad angle; lower edges of the lip with occasional yellow flecks; the prefrontal and in- ternasals with lighter flecks; chin yellow save on anterior labial sutures; the first black band begins one and one-half scale rows back of the parietals; there are 25 grayish-white rings encircling the body, becoming somewhat widened ventrally and yellowish- white in color. These rings are bordered by black rings which nar- row, as they cross the ventrals, to the width of one ventral; the red bands separating the triads are narrowed on the dorsal surface

and rarely (two bands in front of anus) have the red bands almost completely obscured. On the tail there are five triads, separated by red bands which are equal in width to the black and gray triad.

Ventrals, 190; anal single; subeaudals, 50; scale formula 27-21- 23-23-19-17; nasal divided; upper labial, 7-7, the third and fourth entering orbit; lower labials, 9-9, four touching the anterior chin- shields; posterior chinshields somewhat smaller than anterior, sep- arated from each other by small scales; separated from the first ventral by about four seales; frontal rather long, longer than its distance from the end of the snout (7.4 mm. * 5.7 mm.); two postoculars; one preocular nearly as wide as high (loreal on one side elongated and entering eye). Rostral visible above for a dis- tance equal internasal suture; temporals, 1 + 3, 2 + 3.

Total length, 982 mm.; tail, 137 mm.; length of head, 30.5 mm.; width of head, 19 mm.

EHT-HMS No. 5488, an incomplete skin, obviously of this species, was collected by Dr. Hobart M. Smith at El Sabino, Uruapan, Michoacan.

EHT-HMS No. 5253, obtained by Dr. Hobart M. Smith at El Sabino, Uruapan, ee has a color pattern very similar to that depicted by the figure given by Blanchard loc. cit. It presents the following seale characters: Ventrals, 224, subeaudals, 54; scale formula, 28, 21, 21, 19, 19; one preccular, two postoculars; nasal apparently divided; temporals, 2+ 3; 7-7 upper labials; lower labials, 9-9; snout with a whitish band followed by’ a blackish band; labials with yellow-cream spots; anterior labials flecked with black, also some black spots on anterior chinshields. The bands encircle the body; the white (yellowish) bands narrow somewhat on the sides then widen on belly; red bands are not interrupted be- low and lack small black spots. There is a total of 18 triads on body; the tail banded with black and white bands, seven of each, the black twice as wide as the white. In this form the posterior chinshields are equally as long as the anterior.

A second specimen belongs to the variety of nelsoni which Blan- chard believes suggests intergradation with annulatus. In this speci- men (EHT-HMS, 15868, 15 km. west of Morelia, Michoacan) the red bands are encroached upon both dorsally and ventrally until the

red appears as spots on the sides (sometimes the red spots barely touching medially).

Ventrals, 107; tail with tip missing; 18 triads on body; one on head; proximal bands on tail show no red; anterior and posterior chinshields equal; 7-7 upper labials; 9-9 lower labials; 1 pre- and two postoculars; loreal large; nasal not divided; temporals irregular, 1+ 3, 2 4- 3; preoculars, very large, nearly as long as high.

Lampropeltis triangulum annulata (Kennicott)

Lampropeltis annulata Kennicott, Proc. Acad. Nat. Sci., Philadelphia, 1860, p. 329 (type description; type locality, Matamoras (Tamaulipas, Mexico).

A typical specimen of this species was taken at Mamulique Pass, Nuevo Leon, in June, 19836 (HEHT-HMS No. 5254). Ventrals, 197; caudals, 51; anal single; scales, 28, 21, 21, 19, 19; nasal distinctly divided; upper labials, 8-7 (the first apparently abnormally divided on the right side) ; 10-10 lower labials; labials 4, 5 (8, 4) enter orbit; preocular narrow, nearly twice as high as long; 18 triads on body (one on head); six cream bands on tail; the triads are fused pos- teriorly, only the first two on tail being separated by red; ventrally the cream bands encircle body but the red bands are interrupted (save anterior one) on the ventral surface by large black areas which connect with the black bands. Snout and head black to near posterior part of the parietals; lower labials largely black; cream bands with some pigment laterally.

Two specimens (EHT-HMS Nos. 5252, 5510) were collected by Mr. Dyfrig McH. Forbes at Potrero Viejo and presented to me. The first is quite typical and has the neck band encroaching on the parie- tals and including seventh and part of the sixth labial; this is pre- ceded by a very narrow semicircular band; remainder of head black above save for yellowish-cream spots tending to form a band behind nostrils. Twenty-four triads on body; eight on tail; however, the last two or three are coalesced, eliminating the red; red bands nearly as wide as the triads; all scales tipped with black; dorsally the cream bands between the black bands are about one scale wide; all bands encircle body, but rarely the cream band is interrupted by a black spot.

No. 5510. The head markings of this specimen are similar to the preceding. The light, narrow band across the snout is complete.

Two specimens of a Lampropeltis collected at El Limoncito, about 15 km. north of Acapulco are referred to this form tentatively. The specimens show no evidence of mixture with Lampropeltis triangu- lum nelsoni.

The specimens (EHT-HMS Nos. 5512, 5513) have the following scale characters respectively: Ventrals, 217, 219; anal single; sub- caudals, 52, 41; scale formulae, 28-21-21-19-19, 28-21-21-19-19; upper labials, 7-7, 7-7; labials enter eye, 3 & 4-3 & 4,3 & 4-3 & 4; lower labials, 9-9, 9-9; labials touch first chinshields, 4-4, 4-4; triads (2 black bands, one dirty cream) on head, 1-1; on body, 15, 15; on tail, 4, 4.

The nasal is definitely single without division above or below the nostril; the second pair of chinshields are one-half or less the length of the first pair; one-half of the chin and the head to the back part of the parietals, solid black. The plate shows the detail of markings. Black red and yellow bands encircle body. Some of the red ventrals have some darker pigment. The scales of the cream bands have brownish-black spots, as do all of the red dorsal scales.

Four specimens of this species were acquired from a single locality near Huajintlin, Morelos (km. 133). All agree with the figure (Taylor loc. cit.), save that two lack the dark bar bisecting the light nuchal ring; these two, however, have an elongate black spot on anterior edge of the nuchal ring; the first large nuchal dark band is notched anteriorly and is completely separated from the dark bands on sides of head.

present on one side; lower labials are 9-9 the last small, resembling a body scale; two preoculars, and two postoculars. The loreal is about as high as long, squarish or rectangular. In the order given the number of spots on the body and tail (when complete) of the speci- mens is: 10-8, 15-10, 11-8, 10-?, 14-?, 19-12. The females have the higher number of spots on body. However, the number of spots on the male from Campeche equal those of a female from central Vera- cruz.

Giinther gives the date of publication of H. depper as June 7, 1860; and for elapoides, June 26, 1860. I am unable to verify either of these dates. If they are correct the name deppe7, given by Peters, inust take precedence.

Diagnosis. Black with lighter dorsal bands, breaking up into flecks and indefinite spots behind. Scales in seventeen rows; upper labials, 6-6; anterior chinshields much longer than second pair; loreal elongate, rectangular, not entering eye; lower labials, 6-6; ventrals 198; subeaudals 65; all scales save two outer rows keeled.

TAYLOR: SOME MEXICAN SERPENTS 47]

Description of type. Adult female; body somewhat compressed ; head elongate; part of rostral visible above, distinctly less than half the length of the internasal suture; internasals much wider than long; the seales distinctly oval on outer margins; prefrontals wider than long; frontal a little longer than the distance from the tip of the snout, somewhat shield-shaped; length of parietal reaches from parietal to middle of internasal; nasal scale constricted near its middle, but not or only partly segmented, the posterior part with a strong depression posterior to the nostril; loreal nearly rectangular, one and a half times as long as high, not entering eye; two pre- oculars; two postoculars; supraoculars much wider posteriorly than anteriorly; temporals 1 + 1+ 2, the last two large, extending more than half their length behind last labial; upper labials, 6-6, the first strongly notching the nasal, third and fourth entering orbit; having the following ascending order of size: 1, 2, 4, 3, 6, 5; anterior chinshields much longer than second pair; latter very short and broad, in contact, separated from first ventral by a pair of scales; one scale between first ventral and last lower labial; latter 6-6, four touching anterior chinshields; diameter of the eye equal to distance of eye to nostril; scales keeled save on the two outer rows; scale formula 19 (about head)-17-17-17; ventrals, 198; sub- caudals, 65; anal single; total length, 508; tail, 103; length of head, 17; width of head, 8.

Color. Above deep purplish-black, anteriorly with narrow hghter bands which posteriorly become broken up into irregular flecks and spots; head black with a few minute whitish flecks. Chin, cream with a very heavy pigmentation, the color pushing up across back of jaw forming two rounded spots on sides of nape, separated medially ; first broad, black band 11 scales long, medially, is very narrowly interrupted on ventral surface of neck; other dark bands reaching onto edge of ventrals; coloration of venter creamy-white, anteriorly, finely peppered with pigment, then with pigment intermingled with distinct small spots, increasing in number to tail; tail purplish below with some cream marking.

Remarks. This species appears to be most closely related to T. fasciatus, having seventeen scale rows, and an elongate loreal. It differs in a longer, narrower head, six upper and six lower labials, the two outer scale rows unkeeled, and apparently a higher ventral count: from the other recognized species, it differs as follows: from phiippi Jan and occidentala Oliver it differs in having 17 instead of 15 seale rows, and a different coloration; from sartorii Cope and

On the assumption that Coluber sitbon Linné (Syst. Nat., I, 1758, p. 222, No. 264) is a synonym of Coluber nebulatus, the name sibon has been chosen to replace nebulatus. I believe there is serious doubt that the two are synonyms and, that the name sibon should apply to an American snake. Linné regarded the species African, the name sibon being presumably a Hottentot name for an African species according to Seba (Vol. I, p. 22).

According to Daudin (Histoire Naturelle des Reptiles, Vol. VI, year XI, p. 435) “Linnaeus a décrit cette couleuvre d’aprés nature; il en a observé un individu garni en dessous de cent-quatre-vingt erandes plaques, et de quatre-vinet-cing double plaques. Selon lu, la couleuvre sibon est d’un ferrugineux parsemé de blane en dessus, et le dessous est blane avee des taches brunes; de plus la couleur de la téte est blanche.”

The type of Coluber nebulatus is extant (see Anderson Catalogue of Linnean Type-specimens of Snakes). Bihang till k. Svenska Vet.- Akad. Hand. Band 24, Afd. IV, 1899, p. 19.

A single specimen (EHT-HMS No. 5516) was collected near Palo Gordo (km. 386), Guerrero. The specimen is marked above with numerous, irregular, transverse black or brown markings which may extend entirely across the body or, more frequently, are broken into two or three parts. The edges of the spots are very irregular; be- tween the spots the greund color is whitish, flecked or reticulated heavily with very tiny brown flecks. However, some of the scales may be pure white along the edges of the larger spots. The nuchal dark spot shows an inverted V-shaped series of white dots border- ing it anteriorly; there is an occipital blackish spot with varied dark marking on the remainder of head; a dark line from eye to jaw angle; upper labials whitish some with more pigment than others; chin and lower surfaces white with a series of more or less alternat- ing quadrangular black spots, on the sides of the venter and numer- ous small black flecks seattered between them; chin and throat, lightest; the under surface of tail darkest.

Collecting in the neighborhood of the village of San Felipe, near the city of Oaxaca, I obtained a specimen of Trimorphodon tau Cope (EHT-HMS 5507) from under a small rock on an open pastured hillside, August 19, 1938; three days later a second specimen (EHT- HMs, No. 5506) was obtained on the hills west and somewhat north of the city of Oaxaca from under a rock on a similar open hillside. The two specimens are adults, one male and one female, and both differ in coloration from the very young type, as well as in certain details of squamation. These appear to be the only adult specimens known.

Description of Trimorphodon tau Cope (EHT-HMS 5506). Head rather small, somewhat differentiated from neck; body strongly com- pressed; rostral broader than high, bent back over snout, the portion visible above wider than internasals, almost double the length of the internasal suture; internasals distinctly broader than long (not “‘as broad as long’); prefrontals quadrangular, about as long as broad; anterior border of frontal transverse, the sides curving back to the posterior point (sides not with ‘‘straight lateral margins”), longer than its distance from tip of snout, only minutely shorter than parietals; latter relatively short, their length equal to their distance

from internasals; supraoculars strongly widened posteriorly; nasal completely divided, the nostril an elongate diagonal slit; the two scales together form a rectangle; anterior loreal much higher than nasal with a long entrant angle between prefrontals and internasals; second loreal lower than first, touching two labials on one side, one on the other (in No. 5507 this scale has a small part segmented above, and the upper part of the third labial is segmented, making two extra loreal scales; the type has three loreals) ; three preoculars ; the upper largest and separated from the frontal; three postoculars ;

5507: 34, 23, 23, 20, 16). Most of the scales bear paired apical pits (head seales pitted, pits scattered save that those on frontal are in a lateral row on each side). Ventrals 206, subcaudals 70, total 276; (in the female, No. 5507), ventrals 220, subcaudals 57, total 276; measurements of 5506 and 5507, respectively, in mm.: total length, 537, 580; tail, 103, 84; head length, 16, 19; head width, 9, 13.

Color in life. Grayish-brown to faun above with a series of twenty-three rhomboidal, dark-brown spots on body and ten on tail, edged with black and bordered narrowly by gray-cream; the dark spots are five or six scale rows wide medially, narrowed to a width of two seales laterally, usually extending on ventrals; chin white; throat dirty ivory, washed slightly with salmon and becoming more salmon posteriorly: on sides of body some trace of salmon evident, on sides of venter the ends of rhombs are alternated with smaller black spots; the head has a broad spot curving anteriorly, notched behind, crossing anterior part of parietals and posterior part of frontal; above eyes, two forward-extending projections enclose a curved gray bar between eyes which has an anterior extension reach- ing more or less clearly to rostral; side of head gray-faun; first dark band begins about three scales behind the parietals and includes eleven scale rows on median line; it has a small longitudinal median light spot. The central portion of the rhombs are much lighter, nearly grayish in the middle (solid black in young type).

The second specimen has the dorsal spots somewhat lighter, there being twenty-six on body, and nine on tail; the mark between eyes is discernible, but the anterior projection is lacking. (In neither speci- men is it as distinct as in type.)

Variation. Most of the variations have been mentioned. No. 5507 has the lower labials 12, 12, the upper labials 8-8. In this the seventh labial is segmented on the left side and only the lower segment touches labial border. It appears probable that the condition of six labials in the type is anomalous and apparently Cope suspected that the condition is anomalous. Further specimens from western Tehuantepec will be necessary to settle the problem.

Several specimens of this rare snake were collected by me in 1938. Four specimens were taken on a newly paved road between Cuer- navaca and Tepoztlan, Morelos (KEHT-HMS Nos. 5533, 5534, 59535, 5538) ; five specimens were collected near Huajintlan, Morelos, at or near km. 133. (EHT-HMS Nos. 5536, 5537, 5539, 5540, 5541.)

The young specimen described by Taylor (loc. cit.) had the ground color red. The red color appears to be a juvenile characteristic, since adult specimens from the same and other localities show no trace of the red. The black bands of the young tend to become brown in the adult.

The general color of the body in this series of specimens is gray to faun. The darker bands have black edges and the centers are gray- brown, the seales darker on the edges. Many of the spots are sev- ered by a transverse line of faun. The dark bands are usually inter- rupted medially on the venter, on the anterior part of body, but are more or less complete posteriorly.

Three specimens were taken in 19388. These are EHT-HMS No. 16146, from 20 km. south of Zacualtipan, Hidalgo, August 9, 1938; elevation about 2,300 meters; Radclyffe Roberts collector. No. 16147, about five km. northwest of Tianguistengo, Hidalgo, August 11, 1938, elevation about 1,700 meters, Taylor collector. No. 16148, 10 km. south of Linares, Neuvo Leon, September 13, 1938, Taylor collector. These specimens, in the order given, present the following data; sex or age, 2, yg., ¢ ; ventrals and subcaudals, 199-81, 200- 83, 192-75; anal, divided in all; spots on body and tail 29-17, 31-19, 22-10; preoculars, 3-3 in all; postoculars, 2-2 in all; temporals, 14+2-+3 all; upper labials, 8-8, all; lower labials, 10-10, 10-10, 9-9; the upper preocular broadly touches the frontal; scale formula, 26- 21-23-23-17, 27-21-23-23-17, 28-21-23-23-16.

Number 16148 differs markedly from the other two. It is a full- grown specimen, with the large tranverse black bars, reaching to outer scale row; the alternating bands are dull pinkish, one and one- half to two and one-half scales wide in middorsal line, and one-half to two seales wider at the outer scale row. This type of coloration is more typical of the northern, lowland forms. The dark bars on the young specimen are narrower than the intervening pinkish areas which expand to a width of five scales on the side; the dark bars reach the second scale row on sides, as is true of No. 16146. All have the pigment on outer edges of ventrals with the entire underside of tail more heavily pigmented.

A specimen of this species (KHT-HMS No. 5590) was captured under a stone near km. 170 on highway south from México, D. F.

The markings are typical with 24 spots on body and 17 on tail; preoculars, 4-3; postoculars, 2-2; upper labials, 8-8; lower labials, 10-10; two pairs of chinshields of near equal length; temporals, 1 + 2; scale formuia, 27-21-21-19-17; ventrals, 166; subcaudals, 88; anal divided. The specimen is a young male with scales on posterior part of body keeled.

The type locality of this species is “Guanajuato,” (city or state?). The types are males, having 172, 176 ventrals; 55, 55 subcaudals.

A series of specimens from Western Mexico were collected by me on a hillside between Zitacuaro and the Rio Tuxpan in Eastern Mi- choacdn. These specimens are EHT-HMS Nos. 15898-15908, and respectively have the following ventral-subcaudal counts: 9 , 186- 58239; 9, 185-49—234; 9 , 180-57=2387; ¢ , 181-50=—231; 9, 179-52=231; 9, 186-50—236; 3g, 170-58=228; ¢g , 175-60=235, S , 165-54=219; 9, 185-46=231; 3g, 166-58=224. The average of the totals for females is 234.2; for males 226.5. The maximum number of ventrals for the species is 186; the minimum being 165, a difference of 21 scales. This is indicative of a very wide sexual variation, the variation within each sex being only eight in females and ten in males. This lot shows almost the maximum-minimum variation of the species. I have one male with 163 ventrals from Cuernavaca, Morelos, and a specimen has been recently reported from Distrito Federal with 195 ventrals. This latter may represent a race of this species. It should be reéxamined.*

The following specimens from more Eastern localities have been collected; EHT-HMS Nos. 15918, 15914 from near Cocoloapam, about 22 km. northwest of Tehuacan, Puebla.

These specimens, in the order given above, have the following scale counts: ¢, 176-52=228; g , 176-48=224.

No. 5239, reported in Taylor and Smith, loc. cit., from Cuernavaca has a prominent light spot on the anterior part of each parietal. A pair of spots on the suture between the parietals. The light collar is somewhat curving and the frontal is proportionally wider. No. 14431 is the largest specimen seen; it measures total length, 396 mm.; tail, 62 mm.

A large female specimen, No. 15915, is doubtfully referred to this species. It is from an unknown locality and differs in having the last two labials very high, the temporals 1+ 1-1, the last very large; there is a tendency for the nuchal collar to be interrupted medially. Ventrals 183; tail broken.

The lot of specimens (Nos. 15898-15908) from between Zitacuaro and the Rio Tuxpan, are rather constant in general characters. All are more or less dusky brown with a black or black-brown head.

Three of the specimens show the unusual condition of having the last upper labial (the seventh) in contact with the parietal on one side or the other. In one specimen two labials touch the parietal on one side, and here there is no anterior temporal present. One of two specimens taken four miles east of lake Patzcuaro, has the last labial touching the parietal on one side; the other specimen has the long anterior temporal segmented on one side into two scales.

Certain of the specimens have a decided reddish-brown coloration, which in two cases was associated with specimens with the presumed anomalous relationship between labial and parietal.

In 1938 I collected three specimens of this species in an old lava flow between Cuernavaca and Tepoztlan (EHT-HMS Nos. 15941, 16256, 16257). The following variation from the figure 5 (Taylor loc. cit.), is evident.

No. 15941, ¢. The anterior angle of frontal is more obtuse; the posterior chinshields are a little longer; lower labials, 6-6; parietals longer than their distance to the end of the snout; the second labial touches the prefrontal and the fifth is in contact with the parietal; ventrals, 120; subcaudals, 38. No. 16256, ¢. The second labial enters the orbit minutely; the front edge of frontal nearly straight; 130 ventrals, 28 subeaudals. No. 16257, 9. This agrees save that the fifth labial is minutely separated from the parietal, permitting the first temporal to touch the postocular. Ventrals, 130; sub- caudals, 29.

Micrurus nuchalis Schmidt, Zoél. Ser. Field Mus. Nat. Hist., Vol. XX, 1933, pp. 35-36 (type description; type locality Tapanatepee Oaxaca, Mexico. MCZ No. 27830).

A specimen of this rare snake, EHT-HMS No. 5085, which I col- lected in the edge of Acapulco, Guerrero, was sent to Dr. Karl P. Schmidt for identification. He comments that it is far northwest of the known range in Oaxaca.

The following characters obtain: Upper labials, 7-7; lower labials, 7-7, last small; preocular broadly in contact with the posterior nasal; one preocular, two postoculars; temporals, 1 + 1+ 1; ventrals, 220; anal divided; subcaudals, 55, all but third divided.

Snout black followed by a neck spot with a yellow band between; ten bands of black, edged with yellow, on body; four on tail, which are very much longer than those on body. Body bands about two to two and one-half scales wide bordered by yellow covering one scale row; the bands may break on outer scale row. Intervening

red areas are 17-23 scale lengths long, each scale flecked with brown- ish-black at its apex. Black bands on tail cover about twelve scale rows.

Micrurus laticollaris Schmidt, Field Mus. Nat. Hist., Zodl. Ser., 20, p. 39, 1933, and 1936, p. 215-216, fig. 27.

The first specimen of this rare snake acquired (EHT-HMS No. 4578, Taylor, 1932) was from under a loose ledge of rock pried from a tiny cliff at Mexcala, Guerrero. The snake was coiled when it fell, but immediately became surprisingly active. Schmidt has published a figure of this specimen (1936, p. 216).

Two other specimens were acquired by Dr. Hobart M. Smith at El Sabino, Uruapan, Michoacan in 1986 (KHT-HMS 5083, and 5084). In color pattern they are very similar, but the black flecks on the red areas are not all equal, some forming small blotches covering two or three scales. These are very irregular and do not form rings of spots; posteriorly the spots are absent and the flecks are evenly distributed. There are eight black triads (three black bands separated by two yellow bands) separated by red areas in the first of the two; nine triads in the second specimen. In each the last triad extends onto the tail. On tail there is one caudal triad.

In the armature of the head only one significant difference obtains. In the Michoacan specimens the third labial contacts the eye, pre- frontal, and the posterior segment of the nasal, separating the nasal and preocular; in the Guerrero specimen the preocular touches the posterior nasal and separates the third labial from the prefrontal. The upper labials are 7-7; lower labials, 7-7; one preocular and two postoculars; temporals, 1+ 2-+ 2; four labials touching anterior chinshields which equal second pair in length; frontal small, narrow, scarcely as long as its distance from tip of snout. These characters apply to all three specimens. The ventral-subcaudal counts are No. 5083, 9 , 224-14 + = ?; No. 5084, 9 , 225-42 — 267; No. 4578, 9, 246235: 25k.

hesitation, since the color pattern, while agreeing with the type description in general, differs in certain detail of the color pattern. The color in life was as follows: Anterior black spot on head covers snout, tip of chin and the anterior labial, and extends dorsally to and includes the anterior two-fifths of the parietals; the yellow band following this widens on the side and includes most of the anterior temporal and most of the fifth labial. First black band encircles back part of head and neck, and connects dimly below with the black on tip of the chin. Counting this band, there are eighteen black bands covering about six scales above and four to five ventrals below; dorsally the bands are edged with continuous or disconnected yellow dots covering one scale or less; the interven- ing red bands bear dark flecks varying in size on the apices of the scales; ventrally the red areas may have dark flecks which may be confined largely to the outer edges of the ventrals. Tail with five wide black bands separated by narrow yellow bands (2 scales wide).

The frontal width and length, 2.2 mm. * 3.3 mm. The parietal length is 5.2 mm; the width of the preocular is 2 mm. The pre- ocular touches the posterior nasal; temporals, 1 + 1-+ 2; anterior chinshields shorter than the posterior. Ventrals, 207; anal divided; subcaudals double (save third), 43.

Micrurus affinis affinis (Jan) Micrurus affinis affinis Schmidt, Zodl. Ser., Field Mus. Nat. Hist., XX, 1933, p. 36.

There are two specimens (EHT-HMS Nos. 4577-5086) identified by Mr. Karl P. Schmidt as belonging to this species. They agree in the following characters. Upper and lower labials, 7-7; one pre- ocular touching nasal; two postoculars; posterior chinshields longer than anterior. The scale formulae are, 19-15-15-15; 21-15-15-15; ventrals and subcaudals, g 202-45-247; 9 224-36-260. In No. 4577, the spot of black covers the snout and anterior part of the lower labials; the yellow band following is narrow and runs forward on the sides of head reaching the second labial. The nuchal band is about five scales wide, and does not encircle the throat. There are ten very narrow, black bands on the body; five broad bands on the tail. Below, the body bands are about as wide as one ventral. In 5086 ¢@ , the nuchal band encircles the neck. There are twelve black bands, about the width of two ventrals, encircling body; four black bands on tail, 6 or 8 scales wide.

The former specimen is from Cordova, Veracruz; the latter from Cuautlapa, near Orizaba, Veracruz.

Agkistrodon bilineatus Ginther

Ancistrodon bilineatus Giinther, Ann. and Mag. Nat. Hist., 3d ser. XII, 1863, p. 364 (type description; type locality, Pacific Coast of Guatemala).

This species is represented in the collection by two specimens; EHT-HMS Nos. 5357 from El Sabino, Uruapan, Michoacan (head only); No. 5514 from km. 833 between Villagran, Tamaulipas and Linares, Nuevo Leon, presumably in the latter state. It was en- countered June 9, 1938, crawling on the highway pavement about dark.

The color in life was as follows: Head grayish-black above, more grayish on the sides of head and chin; a yellowish-white line from tip of snout along the canthus rostralis to angle of the Jaw, where it joins a line originating on the anterior nasal which runs across the labials and across angle of the jaw; below the white line on labials, the lip is edged with amber-orange; a vertical stripe on rostral which is white with amber-orange center; this connects, when mouth is closed, with a stripe extending back from mental to the posterior chinshields and then bifureates, the lines continuing back to first widened ventral. The lines are here joined by another white line; two amber-orange lines extend from sixth lower labial diagonally — to the bifureating lines.

Body generally lavender gray, traversed by lighter gray, irregular, saddle-like blotches, with interrupted amber-orange borders, which join and form a large amber-orange spot low on side; intervening areas may be divided by a very dim medial band, which joins a black, light-edged spot on the ventrals. Belly generally dark with amber-orange spots and reticulations. Tail yellow-green.

This specimen presents the following scale data: scale formula, 37, 28, 23, 21, 19; ventrals, 1384 (last one fused with half of the divided anal); subcaudals, 35 single + 2 divided, + 3 single + 12 divided = 52. Tail terminates with three greatly thickened scales (abnormal?).

Compared with a No. 5357, the head scales differ as follows: frontal entire (broken into five parts, four anterior symmetrical) ; prefrontals in contact (separated by an elongate scale); rostral wide at the top (narrowed at top). In both specimens there are three preoculars; two postoculars, and one subocular; scale border- ing pit below, elongate. Temporals, 6-5-4 (5-6-5). In both speci- mens there is a tendency for the parietals to be segmented irregularly or partially segmented.

Apstract: The paper treats of herpetological novelties from Mexico, Central and South America; the following new species are included: Bufo gemmifer, La Venta, Guerrero, Mexico; Bufo mazatlanensis, Mazatlan, Sinoloa, Mexico; Tomodactylus angustidigitorum, Quiroga, Michoacan, Mexico; Tomodactylus macrotympanum, Jacala, Hidalgo, Mexico; Microbatrachylus gen. nov. (type species Hleutherodactylus hobartsmithi (Taylor) ; Microbatrachylus albolabris, Cérdoba, Veracruz, Mexico; Microbatrachylus oaxacae, Cerro San Felipe, near Oaxaca, Oaxaca; Microbatrachylus minimus, Agua del Obispo, Guerrero, Mex- ico; Hyla melanomma, 7 mi. east of Chilpancingo, Guerrero, Mexico; Hyla forbes: Acultzingo, Veracruz, Mexico; Hypopachus ovis, Tepic, Nayarit, Mex- ico; Hypopachus maculatus, San Ricardo, Chiapas; Hypopachus caprimimus, Agua del Obispo, Guerrero, Mexico; Hypopachus alboventer, 8 miles east of Cuernavaca, Morelos, Mexico; Hypopachus cuneus nigroreticulatus, Encarna- cidn, Campeche, Mexico; Leptotyphlops magnamaculata, Utilla Island, Hon- duras; Leptotyphlops rufidorsum, Lima, Peru; Leptotyphlops nasalis, Managua, Nicaragua; Leptotyphlops ater, Managua, Nicaragua; Phyllodactylus muralis, Totolapam, Oaxaca, Mexico; Phyllodactylus magnatuberculatus, Acapulco, Guerrero, Mexico. Several other rare forms are discussed. Most of the new forms are illustrated.

HE following paper is based upon material that has been accu- mulating in the EHT-HMS collection for several years, but descriptions were held back in some cases in order to obtain more adequate series of specimens. It was originally intended to treat of certain of the genera monographically and in separate papers; but to do this would have delayed publication of the new forms for some time. Four of the species are described from specimens in the U. 8. National Museum collection. The excellent drawings are by Walter Yost, of the University of Kansas; the photographs by Dr. Oren Bingham, University of Kan- sas photographer.

Bufo gemmifer sp. nov. (Plate LIII; figs. 3, 3a, 3b)

Type. EHT-HMS No. 18509; El Limoncito, near La Venta, Guer- rero; June 29, 1938; E. H. Taylor collector.

Paratypes. EHT-HMS Nos. 18497-18508; topotypes, same date and collector.

Diagnosis. A large toad with strongly developed preorbital, supra- orbital, postorbital and supratympanic crests; a canthal crest more or less developed; supraorbital crests forming continuous curves which diverge strongly; interorbital width much greater than width of an eyelid; only a faint suggestion of parietal crests; parotoid gland much smaller than eyelid; heel reaches to parotoid or slightly behind; snout sharply truncate; subarticular tubercles of hand usually bifid; these and supernumerary tubercles highly elevated, sharply conical; vocal sac usually with a single opening which may be sinistral or dextral (rarely double).

Description of the type. Adult male. Head broader than long, with a high, narrow, curving supraorbital crest which is continuous with the supratympanic crests, and together form a sigmoid curve; supratympanic crest forms a shelf which extends out above the tym- panum, partially concealing the tympanum when seen from above; only a vague trace of parietal crests; very distinct post- and pre- orbital crests; canthal crests less clearly defined, extending to above nostrils; snout truncate, sloping sharply to the rather pointed tip of upper jaw; loreal region rather concave, the lores sloping rather sharply; tympanum subcircular, its greatest diameter (6.1 mm.) greater than half the diameter of the eye (9.7 mm.) ; tympanum sep- arated from the postorbital crest by an appreciable distance; an in- distinct, irregular crest, beginning below middle of eye, continues to below tympanum; width of an eyelid (7 mm.) less than narrowest width between the crests (9 mm.); supraorbital crests diverge strongly; width between the supratympanic crests (27 mm.) some- what less than greatest width of the head (32.5 mm.) ; parotoid gland small, oval to subtriangular, lying somewhat diagonally behind the end of the supratympanic crest.

Tongue elongate, rounded and widened posteriorly, narrowed in front, free for little more than one-third of its length; choanae small, narrow, transverse, with a prominent transverse ridge behind each; opening of vocal sae dextral.

First finger larger and longer than second; two large palmar tu- bercles; distal subarticular tubercles of outer three fingers double or

TayLtor: HerrrrotocicAL MIsceELLANY 491

bifid; strong conical tubercles on palm and sides of digits; inner sur- faces of first finger with nuptial asperities which are present also on second and third. Foot more than a third webbed, the edges of the digits with a distinct serrate fringe; subarticular tubercles not strongly differentiated from other tubercles on digits and soles; inner metatarsal tubercle oval moderately salient larger than outer; a rather conspicuous irregular row of tubercles in place of a tarsal fold.

Skin strongly tubercular, with two rather prominent rows on back joining anteriorly just back of the parietal region; tubercles on sides a little larger than most of the tubercles on the back; tubercles coni- cal, studded with one large and several small, horny spines (in fe- males the tubercles usually have a single, rounded, horny tip) ; tubercles low, indistinct on dorsal surface of hand and foot; two or three enlarged tubercles behind angle of the mouth; two pairs of tubercles above the anus.

Color. A very indistinct median stripe and a very indistinct, di- agonal, lateral stripe; head nearly uniform olive-gray, the crests dark black-brown; arms and legs irregularly barred or marbled with dark olive or blackish; posterior sides of femur reticulated with darker color; below dirty white (the pigment scattered between the tubercles) ; tympanum blue-black; under surface of hands and feet darker than venter; an inverted V-shaped black mark terminates the dim median light stripe anteriorly; lip cream, with horny tu- bercles and a rim of dark horn at edge.

Measurements. (Type and largest female; measurements in mm.) ; snout to vent, 90, 99.5; length of snout, 10, 9; length of eye, 9.7, 10.8; diameter of tympanum, 6.1, 6.7; length of parotoid, 8.3, 11; distance between supratympanic crests, 27, 30; arm, 52, 56.5; leg, 99, 107; tibia, 31.5, 36; foot, 45, 48.

Variation. The opening of the vocal sac varies. In five speci- mens the opening is sinistral, in four dextral, and in two, there was an opening on each side; in most of the specimens the tympanum was well separated from the crests; certain specimens have the limbs more conspicuously barred, and the median and lateral stripes con- trast more with the general coloration; in others these stripes are almost entirely obsolete. Usually the subarticular tubercles of hand and the distal tubercle of the fourth toe is completely divided or bifid; more frequently only a pair of tubercles is present above the anus.

Remarks. The discovery of this species was a great surprise since I had collected in this general region on several previous occasions. On the night following the hurricane which occurred on

499 Tue UNIversiry ScriENCE BULLETIN

June 26, 1938, numerous amphibians were heard calling in the vi- cinity of my camp. The first night the following were heard calling and specimens of all were taken: Bufo marmoreus, Bufo marinus, Microhyla usta, Hypopachus caprimimus, Hyla baudinu, H. stauf- feri, H. venulosa. The second night following, the same species were heard or taken. The third night the numerous Hyla stauffert were replaced by Hyla underwoodi, and the Bufo marmoreus disappeared from the scene and were replaced by the species here described. On succeeding nights the species was not heard or found again, despite what appeared to be favorable conditions for their appearance.

This form is most closely related to Bufo mazatlanensis occurring in Sinaloa and Nayarit. These differ in having the crests some- what less elevated; a shorter supratympanic crest; a more salient inner metatarsal tubercle, and only the third digit of hand with a divided subarticular tubercle. The smaller tubercles of sole and palm are much reduced. The parotoid gland is larger and placed farther forward. (Compare with valliceps; pl. LIII, fig. 2.)

The species name is in reference to the old belief that the toad carries a jewel in its head.

Bufo mazatlanensis sp. nov. (Plate LIII, fig. 1; Plate LIV)

Bufo valliceps Taylor, Univ. Kansas Sci. Bull, XXIV, 1936 (1937), pp. 509-510.

Type. EHT-HMS No. 374; two miles east of Mazatlan Sinaloa, Mexico; July 20, 1934, E. H. Taylor coll.

Paratypes. EHT-HMS Nos. 373-379; same data.

Diagnosis. A large toad with a known maximum size (@ ) 86 mm.; related to gemmifer, but with a pronounced dorsal stripe, nar- rower head, the parietal crests more distinct, shorter snout, a larger, more transversely placed parotoid; supratympanic crest shorter, not - forming shelf above tympanum; all crests topped with black horny epidermis.

Description of the type. Head somewhat wider than long; crests high and narrow; well-developed supraorbital crest which curves behind eye to the supratympanic crest; postorbital and preorbital crests well developed, the latter narrowly separated from the low horncovered crest on the upper jaw; thickened canthal crests, more or less horn covered, extend to a point between nostrils; supratym- panic crest does not or only slightly projects over the tympanum and does not conceal tympanum when observed from above; parietal crests moderately developed.

TAYLOR: HERPETOLOGICAL MISCELLANY 493

Snout very truncate the nostrils extending as far forward as the upper lip; loreal region somewhat concave; tympanum subcircular the crests forming the upper anterior border, its greatest diameter (6.1 mm.) much less than length of eye (8.5 mm.) ; latter slightly less than distance from eye to tip of snout (8.9mm.); width of an eyelid (6 mm.) less than interorbital distance (measured from tops of crests, 9.3 mm.); width between the supratympanic crests (23 mm.) less than width of head (29 mm.); length of parotoid (10 mm.), lying diagonally, separated from eye by a distance of 6 mm., abutting against the termination of the supraorbital crest. Tongue elongate, rounded, widened posteriorly, narrowed in front, free for a third of its length; choanae moderate, a high ridge behind each; each with a curved anterior ridge, the innermost edge of which forms a toothlike free process (also in gemmifer); (character of - vocal sacs in male unknown). Limbs more slender than in gemmi- fer; first toe longer than second; two large palmar tubercles; distal subarticular tubercle on third finger bifid; tuberculation on fingers and palm rounded, but not spinose or conical.

Tibiotarsal articulation reaches the tympanum; subarticular tubercles of toes single; supernumerary tubercles somewhat more conical on hand, but much less prominent and fewer than in gem- mifer; foot nearly half webbed, slightly more extensive than in gemmifer. Inner metatarsal tubercle high, with slightly compressed inner edge, its greatest length about that of first toe; outer tubercle elongate; tarsal fold represented by a few, larger, spinose tubercles. Skin strongly tubercular, the tubercles tipped with brown horn (a single point in females or the entire tubercle covered except laterally and posteriorly, where there may be several horny points). Snout and lores with spots of brown horn; tubercles on sides largest; venter with equal, small, tubercles.

Color. An irregular median light cream line terminating at occi- put; diagonal lighter lines on sides scarcely discernible due to mar- bling with brownish; on each side of median lines, indefinite darker and lighter brown areas; legs indefinitely barred and marbled with brown; venter immaculate yellow-cream; crests deep black or black brown.

Variation. Four paratypes are females and save for size are uni- form for most characters; the color is similar save that No. 373 is much lighter than the type (three paratypes are skeletons).

Measurements in mm. Snout to vent, 85; length of snout, 7.2; width of head, 29; length of head, 24; arm, 48; leg, 95; tibia, 28.5;

494 THe UNIVERSITY ScIENCE BULLETIN

foot, 44 (measurements of paratypes are given in Taylor [1987, op. cit.]).

Remarks. The type series was dug out of a pile of rock and earth only a few meters above sea level; their call was not heard.

In Taylor (1987, op. cit.) I state that the specimens were compared with valliceps from Guerrero. The locality should have been Vera- cruz. I have examined the type of argillaceus, and the present species is quite unrelated. In Kellogg (Bull. 160, U.S. N. M., 1932, p. 71) two specimens of valliceps are reported from Acaponeta, Nayarit. I rather suspect that the specimen is not valliceps, since it is several hundred miles out of the known range.

No further comparison with other Mexican toads is needed. (Compare figure 1, Plate LIII, with valliceps, Plate LIII, fig. 2, and gemmifer, Plate LIII, fig. 3.)

Diagnosis. A small member of the genus, known maximum length 25 mm.; digits tapering, the terminations narrower than digits; lum- bar gland very distinct, short, somewhat removed from groin; a dis- continuous fold from eye to lumbar gland more or less distinct; parotoid gland distinct; abdomen strongly granular; tongue large, slightly nicked behind, free for nearly half its length; tympanum small, indistinct, separated from eye by a distance greater than its diameter; limbs relatively short, the heel not or scarcely reaching tympanum.

Description of the type. Head slightly narrower than body, the frontal region narrowed; canthus rostralis distinct, very slightly rounded; upper part of lores nearly vertical, then sloping to lip, leaving a broad, shallow depression between eye and nostril; inter- orbital width (2.35 mm.) only a little wider than eyelid (2.1 mm.) ; length of eye (3.5mm.) about equal to length of snout (3.55 mm.), but somewhat shorter than distance from eye to the tip (3.8 mm.) ;

TayLor: HERPETOLOGICAL MISCELLANY 495

distance between nostrils equals distance of eye from nostril; tym- panum small, indistinct, its diameter about .75 mm., separated from eye by a greater distance (1.1mm.); snout pointed; nostrils not terminal, the distance from tip of snout being 1.2mm. Tongue rather narrow, elongate, free for nearly half its length, slightly nicked behind; choanae lateral, vertically placed, seen from below they are concealed by projections from upper Jaws; mucuous glands have small openings between choanae; openings of the vocal sacs large.

Arm brought forward the wrist reaches the tip of the snout; tips of outer fingers no wider than inner fingers; subarticular tubercles very large, rounding, not conelike; first finger shorter than second; a large median palmar tubercle; the outer palmar tubercle variable; that at base of first finger distinct; four or five other enlarged palmar tubercles and numerous smaller ones; small tubercles be- tween the bases of adjoining digits and bordering basal edges, give a serrate appearance; an indistinct tubercle on wrist and elbow; leg brought forward the tibiotarsal articulation reaches to arm insertion or very slightly beyond; fourth toe long, the fifth very short and slender, the metatarsals of these toes united; subarticular and super- numerary tubercles conical, salient; sole with several large, and numerous smaller tubercles; a large inner metatarsal tubercle, and an equally large outer; no trace of a tarsal fold; when limbs are folded the heels touch.

Skin above relatively smooth; a few flattened, rather indistinct pustules on back; a dorsolateral lumbar gland separated from groin by an appreciable distance; running forward from the gland a more or less continuous fold reaches to near eye, not continuous with the very indistinct supratympanic fold; a parotoid gland lying some- what diagonally behind tympanic region and extending to above arm insertion; abdomen and sides covered with relatively large granules; granules cover most of under side of femur and much of its posterior face; chin and breast smooth.

Color in life. Reddish-brown on dorsal surfaces with some indis- tinct darker flecks and spots; lumbar gland deep black and silvery white; chin pigmented with light blackish-brown; venter lightly — pigmented with brownish-black, the summits of the granules silver; under surfaces of tibia more or less barred with brown and cream; dorsal and posterior part of femur more or less uniform brown; ventral surface of femur flesh; sides of head and lores blackish; snout somewhat more grayish than black.

496 Tue UnNiversiry ScieENcE BULLETIN

Measurements in mm. Snout to vent, 24.2; length of snout, 3.55; snout to arm, 8.5; length of head, 9.3; width of head, 8; arm, 15; leg, 29; tibia, 9.2; foot, 15.2.

Variation. Most of the proportional measurements and the gen- eral structural characters of the paratypes agree with the type. In color they vary to a considerable extent, some being nearly uniform gray-black above; others are deep brown, while still others are brownish-gray with black spots; one specimen shows rather distinct bars on the femur. Females are usually flesh below—and less pig- mented than the type. A few have a rather indistinct light bar be- tween the eyes as occurs in other species. The fold from eye to the lumbar gland may be broken into a row of short folds or pustules. In some the tympanum is entirely concealed, but usually its outline can be discerned. In most the border of the ventral disk is very indistinct.

Specimens were encountered hopping about on the ground or en- sconced under stones. The voice has not been heard. No specimens were found in trees. The narrowed tips of the digits, the shortened limbs and the poorly developed disk may be stigmata of a ter- restrial habitat, despite the fact that none have been encountered save in forested areas. Tomodactylus nitidus, another terrestrial species, has been taken largely in open fields far from forest.

Of the known species, the relationship is probably closest to Tomo- dactylus amulae Giinther. This species lacks narrowed tips on the toes.

Tomodactylus macrotympanum sp. nov. (Plate LV; figs. 2, 2a, 2b)

Type. EHT-HMS collection No. 6838; collected south of Jacala, Hidalgo, Mexico, July 2, 1936, by Edward H. Taylor.

Paratypes. EHT-HMS Nos. 6815-6837, 6839-6840, collected 8-18 miles south of Jacala (by highway) chiefly at a point on highway marked La Placita, and a tiny village Minas Viejas. Same date and collector. i

Diagnosis. A large member of the genus (known maximum size 31 mm.), with the lumbar gland moderately distinct, extending to groin, not colored black and white; tympanum large, very distinct, more than three-fourths diameter of eye; abdominal disk more or less distinct; abdomen not granulate save on sides, and very in- distinctly granulate posteriorly ; enlarged terminal disk on two outer fingers nearly double the smallest width of these digits.

Description of the type. Head about as broad as body; the in-

TAyYLor: HERPETOLOGICAL MISCELLANY 497

terorbital distance (3.7 mm.) much greater than’ the width of an | eyelid (2.4 mm.); length of the eye (3.4 mm.) less than length of snout (4.6 mm.) but equal to the distance to nostril; diameter of tympanum (2.6 mm. wide, 2.9 mm. high), equal to or slightly more than three-fourths length of eye; the rim of the tympanum thickened, overhanging the angle of the mouth; canthus rounded, the lores sloping; region about nostrils only slightly raised, lacking groove or depression between them.

Tongue small, pyriform or bottle-shaped, apparently not nicked behind; choanae lateral, when seen from below almost wholly con- cealed under the projection from the jaw; vocal sacs present, the openings elongate; the sacs indicated on the sides of chin by longi- tudinal folds.

Arm brought forward, nearly half of forearm extends beyond snout; terminations of two outer digits thickened, truncate, nearly twice as wide as the narrowest part of digit. Subarticular tubercles very large, rather rounded, with dim supernumerary tubercles; three posterior palmar tubercles, the median largest more or less con- tiguous with the outer (smallest); two other large, and several smaller tubercles on palm; other small tubercles between and bordering inner basal edges of digits; one or two tubercles on under side of forearm near wrist; other tubercles present on elbow; leg extended, the tibiotarsal articulation reaches eye; digits thickened, but not or slightly widened at tips; no webs, but a thickened tubercle between the bases of adjacent digits may represent a remnant; subarticular tubercles and to a lesser extent the supernumerary tubercles strongly salient, conical in shape and pointing slightly for- ward; sole of foot with about ten enlarged tubercles with numerous smaller granular tubercles; a large inner metatarsal tubercle; outer somewhat smaller; no trace of a tarsal fold; small tubercles on heel; free part of the third finger much longer and extending slightly farther forward than fifth.

Skin above rather roughened, with scattered pustules; upper sur- face of limbs smooth, with a few indistinct pustules on exposed sur- face of leg; sides of neck and body and the posterior part of abdomen covered with more or less distinct, flattened granules; more than half the under surface of femur granular, and part of the posterior surface; the granules of the back part of the underside of femur are more or less fused, forming transverse rows. A large lumbar gland extending nearly half the distance between axilla and

groin, somewhat granular above, with pits (visible under the lens) ; the edges of the glands are not strongly defined save by the presence of the pits; an ill-defined parotoid gland lies behind the tympanum above the arm and is likewise pitted. Two or three tubercles be- hind lower part of tympanum; the ventral disk is more or less dis- tinetly outlined.

Color. Above gray, with a darker, somewhat symmetrical area extending from between eyes to rump; a gray bar connects the eyes preceded by a darker spot; other dark flecks on sides and dor- solateral region; exposed surfaces of arms and legs with darker flecks or bars. Femur and foot grayish, with alternating cream and gray areas scarcely differentiated. Below cream-flesh with a thin peppering of pigment. Front face of femur and groin with less pigment. A few light spots on upper and lower lips.

Measurements. Snout to vent, 29.8 mm.; length of snout, 5 mm.; snout to foreleg, 10.5 mm.; width of head, 11.1 mm.; length of head, 11 mm.; arm, 19 mm.; leg, 42.4 mm.; tibia, 18.3 mm.; foot, 21.2 mm.

Variation. In most of the structural characters listed the paratype series is practically uniform. In the distribution of pigment on the dorsal surface there is considerable variation. In some specimens the pigment is scattered in small dark flecks on the gray ground color; in others there is greater concentration of the pigment and there are fewer, but larger spots. The light bar across the head is usually evident, and some of the specimens have no darker area preceding the bar. In practically all, the chin, throat, breast and most of the abdomen are smooth. Folds on chin may be wanting.

Remarks. Most of the specimens are males. They were for the most part obtained from low trees and shrubs at an elevation be- tween 6,000 and 7,000 feet, on a rainy night. The call sounds much like a short whistled note, pitched about five notes above middle C. Perhaps blinded by the light, they remained quiet at my approach. The call is such as to render its source difficult to locate. However, once found, the specimens were taken without difficulty.

The relationship is probably with Tomodactylus nitidus from which it differs in the much larger, more distinct tympanum; skin less pustulous above; longer legs, and the heels overlapping when folded at right angles. The lumbar gland less distinct and not strongly marked in black and white. Terminations of outer fingers more widened.

This adds another species to the distinctive fauna of the state of Hidalgo.

TAYLOR: HERPETOLOGICAL MISCELLANY 499

Among the specimens of Eleutherodactylid frogs collected in Mex- ico during the last eight years by Doctor Hobart M. Smith and myself are some three hundred small specimens, referable to several species which have, in combination, characters that seem to warrant their separation into a genus of their own. Two of these I have al- ready described in the genus Hleutherodactylus, aware that such an association was not wholly justified. I now propose the following genus for their reception:

MIcROBATRACHYLUS genus novum Genotype: Eleutherodactylus hobartsmithi Taylor

Generic description. Very diminutive frogs; hand and foot lack- ing trace of web; outer metatarsals united; terminal disks present or absent; no vocal sacs, or chinfolds; no vomerine teeth; tongue thick, shaped like a grain of maize, free for a third of its length; a flat inguinal gland; ventral disk on venter broadly triangular, terminat- ing on thighs; gonads with black pigment; an elongate, narrow, carti- lagenous omosternum; sternum of cartilage, the posterior extension narrowed medially; the termination indistinctly bifid.

It is especially surprising that these small species have not been encountered by earlier collectors. It is possible that some specimens exist in other collections masquerading under false nomenclature. That these are not the young of various species of Syrrhophus, Tom- odactylus and Eleutherodactylus is attested by the presence of fully adult males and females of the several species. Moreover, the young of most of the known Mexican species are at hand and these are easily identified, since most of the specific characters (size excepted) are evident in newly transformed young. I am of the opinion, based on the size of the ovarian eggs and the presence of specimens in places where standing water is not readily accessible, that most Mexican species of Hleutherodactylus* have direct transformation without a protracted free-swimming larval stage. Thus specific characters are not obscured by adaptations resulting from the free- swimming larval life.

There is strong sexual dimorphism in Microbatrachylus as regards size, and in the diameter of the tympanum. Most of the species are terrestrial in habit, although there is a report of specimens of ho- bartsmitht having been taken in low plants (Taylor, 1937, op. cit.).

The following species are recognized: Microbatrachylus hobart- smithi, pygmaeus, albolabris, oaxacae and minimus. Further study on other forms is necessary and these are not included.

* Eleutherodactylus rugulosus, is apparently an exception since the newly transformed young are abundant along streams. (Possibly EH. natator and vocalis also are exceptions.)

500 THE UNIVERSITY SCIENCE BULLETIN

Microbatrachylus pygmaeus (Taylor)

Eleutherodactylus pygmaeus Taylor, Trans. Kan. Acad. Sci., 39, 1936 (July 2, 1937), pp. 252-254, pl. 1, figs. 3-4 (type locality, one mile north of Rodriguez Clara, Veracruz).

The type of this species is a female. The two paratypes listed belong to two other species of this genus.

A series of specimens belonging to this species was obtained in Potrero Viejo, and Cuautlapa, Veracruz, since the type description was published. Most of the specimens were obtained, both during the day and the night, by tracing their feeble chirps. This usually entailed some difficulty since they are active and their alert move- ment makes them difficult to find in grass and leaves. All were on the ground.

The males of the species are diminutive, the largest of sixteen measuring 16 mm., while most of the others are less than 15 mm. in snout to vent measurement. The largest of fourteen females measures 19mm. in length. It would appear that the sexual dimorphism as regards size is distinctly less than in hobartsmithi. The size of the tympanum is distinctly greater proportionally in the males than in the females of that species. The males of pygmaeus have large tympani, their diameters equal to about four-fifths or more of the diameter of the eyes. In both sexes the characters of the widened tips of the digits, the absence of a tarsal fold or row of tubercles on the tarsus, the absence of a small outer palmar tubercle, the presence of an axillary gland, the absence of vomerine teeth, the presence of the large inner metatarsal tubercle two to three times the size of the outer, may be regarded as constant. I find no vocal sac in the males. The tibiotarsal articulation usually reaches the eye or at most only slightly beyond.

The dorsal markings vary considerably, but the inverted V-shaped marking on the shoulders is invariably present; two small spots are present, in the dorsal lumbar region, and a dark diagonal mark from eye to the side, passing behind the arm, is usually present. A few specimens have a dark interorbital bar, and a dark stripe on the lores is more or less distinct.

The general color of live or newly preserved specimens is lavender or purple, there being no red or rosy color visible as in hobartsmithi.

The data in the type description taken from the paratypes must be disregarded as these specimens do not belong to this species.

The following specimens are referred to this species: Nos. 6419- 6422, 6430-6436, 18187, Cuautlapa, Ver.; Nos. 18127, 18128, 18185- 18187, 21612-21614, 22061, 22061A, 22063, Potrero Viejo, Ver.; Nos.

Dr. Hobart Smith informs me that he obtained nearly two hundred specimens of this species in the general region about Potrero Viejo, Veracruz, during the winter of 1938-1939.

Microbatrachylus hobartsmithi (Taylor)

Eleutherodactylus hobartsmithi Taylor, Trans. Kan. Acad. Sci., 39, 1936 (July 2, 1937), pp. 355-357, pl. 1, figs. 5-6 (type locality Uruapan, Michoacan).

This species was described from a male type, and only males are present in the paratype series. All were found at night by tracing their calls. I collected a series of forty specimens from among grass and weeds near the edge of a small stream about ten miles west of Villa Victoria, México, September 1, 1938. These were taken in the daytime, and no calls were heard. The lot contains only eight males. The females are proportionally very large, reaching a length of 22.5 mm., and more than three times the bulk of the males. The longest male has a snout to vent length of only 15.1mm. The larger females contain large, nearly ripe eggs. The size of the eggs suggest that they have a direct mode of development rather than one involving an aquatic larval stage.

The color patterns are for the most part more strongly ‘defined than indicated in the type figures. The ground color is a pinkish- gray with blackish markings, which are more or less symmetrical on the back. The dorsal and ventral surfaces of the femur are light red. The upper arm is of a rosy cream. The chin and venter are dull flesh or occasionally rosy flesh with a scattering of pig- ment, usually heavier on the chin and breast; in males and a few females the chin is rather blackish. The limbs are more or less barred in all specimens. The tympanum in males is often of almost the same diameter as the eye; in females it is proportionally much smaller, varying from about one-half to two-thirds the eye diameter. In most of the specimens the tongue is a little longer than in the type, with nearly two-fifths of the posterior part free. I am unable to find openings to the vocal sacs, in these males, and a reéxamina- tion of the type shows folds along the sides of the floor of the mouth, but the openings were probably made with a probe. The statement that vocal sacs are present is to be regarded as incorrect.

The granulation of the venter is confined to the posterior parts. Proximal parts of the underside of the femora and a broad triangular patch on their posterior faces, lying below anus, also granular. In

most of the specimens the inner metatarsal tubercle is very large, its length equal to about two-thirds the length of the inner toe above the tubercle, and distinetly larger than the outer metatarsal tubercle. In several specimens the basal subarticular tubercle of the fourth toe is double. The gland in the groin, not mentioned in the type description, is present in all specimens, including the types.

posterior edge rounding, not notched behind, the posterior width about one-fourth greater than the anterior width, free for one-third its length; choanae small, lateral, completely concealed by projec- tions of upper jaw when seen directly from below.

Arm short, laid forward the wrist does not reach tip of snout; first finger shorter than second; subarticular tubercles distinct, rounded, moderately salient; a large tubercle at base of first finger ; a large, rounded, median palmar tubercle; no trace of an outer tubercle; five supernumerary tubercles on palm; tips of two outer fingers with disks having a terminal groove; the disks at least one- third wider than the width of the digit; those of inner fingers scarcely wider than digit; no trace of a web; a row of rounded tubercles on under surface of forearm; leg rather short, the tibiotar- sal articulation reaching the posterior corner of the eye; disks on toes slightly larger than those on fingers, with a terminal groove; subarticular tubercles large, somewhat salient; only one or two supernumerary tubercles, these on the back part of sole; inner metatarsal tubercle oval, nearly three-fourths the length of the first toe; outer tubercle more than half as large as inner; when limbs are folded at right angles the heels overlap a little.

Skin above on head and body with tubercles and folds; a median hair-fine ridge from snout to anus; a pair of indefinite folds begin at eyelid in interorbital region, converge to a point on shoulders where they run parallel for a short distance, then they diverge, then con- verge, and run parallel for a distance. Again they diverge, and again converge and run more or less parallel to rump, where one or two larger tubercles are to be found; a discontinuous fold or row of tubercles begins behind eye and follows the dorsolateral region to groin; another indefinite row of tubercles runs back from the dim supratympanic folds; sides of body with other indistinct tubercles more or less in rows; the folds above tympanum not pronounced; the gland behind and below tympanum distinct, having characteristics of the gland in groin; latter large, flat, the minute glandules visible through skin; chin, breast, abdomen and the greater part of the underside of femora very smooth; a proximal area on ventral and posterior faces of femur granular. Ventral disk indicated by a transverse fold on breast and two curving lateral folds which con- verge and terminate medially on limbs.

Color in life. Above grayish-cream, with a slight pink or rose cast; top of head dark, inclosing a grayish spot, the anterior edge of which is trifoliate; two dark lines begin on orbital edge of upper lids, fuse on occiput and continue back to rump. as a broad, irregu-

larly edged stripe occupying all the area between the median folds; a dorsolateral dark stripe borders the dorsolateral row of tubercles below; a dark, irregular stripe through lores, across tympanum, above arms to the side, its lower edge deep black; a white stripe be- ginning near tip of snout borders the dark stripe to side; a broken black line on the edge of lip; an ill-defined dark line on lower lip; chin, throat and venter immaculate greenish white; two or three black spots on anterior face of arm and one or two on posterior face; palm purplish; fingers strongly barred above; a brown stripe on anterior face of femur, darkest at knee; very indefinite bars on femur and tibia; sole and heel purplish; toes dimly barred above.

Measurements in mm. Snout to vent, 16.5; length of snout (median), 2; length of head, 5.4; width of head, 4.9; arm, 7.9; leg, 23.1; tibia, 7.3; foot; 10.

Variation. No. 18803 has been preserved in too weak a solution of the preserving fluid and has bloated slightly so that all trace of rugosities or folds on the body have disappeared. The color and markings are similar; the limbs are darker and the dorsal dark and light markings are less contrasted. No. 18802 has the dorsal cream stripes only faintly visible and narrower than in the type; in 6407A, the specimen has become brownish; there is a faint, light hair line in middorsal region, connecting with a similar transverse line on the back of the thighs which passes below anus.

Two specimens from Guerrero are tentatively referred to this species. They differ in certain points, but the median dorsal folds are similar, and a white stripe containing some scattered pigment is present on lip and lores, running back above and behind arm. Both specimens are larger, with proportionally larger outer metatar- sal tubercles, which are somewhat squarish, their free edge directed inward. No. 6408 (1144 mi. N. of Mazatlan, Gro.) is a female with tympanum about two-thirds the diameter of eye; No. 21611 (Agua del Obispo, Gro.) is a male, the tympanum minutely less in diameter than the eye. In the female the borders of the ventral disk form very ample folds. The largest measures 17.8 mm.

Comparisons. This form differs from the white-lipped Eleuthero- dactylus beatae by the absence of a tarsal fold, or tarsal tubercles, larger tympanum and shorter legs. By the presence of the white stripe on the lip it differs from other members of this genus.

Description of type. Known maximum size 18.1 mm. (male). Head nearly as broad as body; snout rather oval; canthus rostralis distinct, but somewhat rounded; lores sloping broadly to lip; the loreal region slightly concave behind nostril; eyes not salient above; width of an eyelid (1.7 mm.) distinctly narrower than the interorbi- tal distance (2.2 mm.); length of eye (2.2 mm.) greater than its distance from nostril, less than length of snout (2.8 mm.) ; nostril a little closer to tip of snout (1.3 mm.) than to eye (1.7 mm.); di- ameter of the circular tympanum (2.1 mm.) practically equal to that of eye.

Tongue much elongated (paratypes show a much shorter tongue), free for at least half its length, not or but slightly notched behind; no vocal sacs; no vomerine teeth; choanae lateral, not concealed by the projection of jaw when seen directly from below; area of palate anterior to choanae much reduced.

Arms short, brought forward the wrist fails to reach snout tip; first finger shorter than second; subarticular tubercles very large, rounding, as wide or nearly as wide as the digits; five small super- numerary tubercles on palm; three posterior palmar tubercles, the median largest, contiguous posteriorly with the outer palmar tuber- cle, or partly fused with it posteriorly; a dim fold under arm, ele- vated at two or three points with tubercles; small pads on tip of dig- its lacking a groove, not wider than the digit; legs long, the tibio- tarsal articulation reaching tip of snout; limbs folded at right angles, the heels overlap two millimeters; outer metatarsal tubercle about two-thirds the length of first toe, moderately elevated, oval; outer more than half as large; toes with pads not or only minutely wider than toes; subarticular tubercles large, longer than wide, moderately elevated; a well-defined supernumerary tubercle on fourth toe be- tween the two proximal tubercles; sole with several dimly indicated tubercles; no tarsal fold from inner tubercle; a row of tubercles run along outer side of tarsus from outer tubercle.

Skin above rugose, pustular, forming a pattern with indistinct folds and pustules; a pustular fold begins at posterior corner of eye,

runs back diagonally to a large tubercle on shoulder which is widely separated from its fellow; situated posterolaterally from this is another enlarged tubercle, which is continuous with a fold that runs posteriorly to groin, broken up into tubercles; beginning at the shoulder tubercles are two fine folds, one on each side, which tend to converge, then run parallel to each other, then diverge to join the outer row of tubercles. Arms finely pustulate, legs heavily pustu- late, the largest pustules on the dark markings; sides pustulate or tubercular; a small (yellow) gland behind axilla and a larger, flat gland in groin; venter very dimly granular in the posterior half; throat and breast quite smooth; a broadly triangular, very distinct suction disk on venter, terminating posteriorly on thighs; a small parotoid above arm and a large tubercle back of lower part of tympanum.

Color in life. General ground color pink or roseate above; con- cealed parts of hind limbs pink; venter yellowish-white to ivory, with scattered, minute flecks of pigment forming a dim reticulation enclosing lighter spots; chin and throat darker; head grayish and black, with spots on lips; a loreal stripe, more or less distinct; dim, radiating lines on edge of eyelid above; a light gray bar between eyes, followed by a blackish bar; two x-shaped marks on shoulders; dim, dark marks on back; a dark spot above tympanum; limbs distinctly barred; palms, soles and undersurface of digits dark, the tubercles cream.

Measurements in mm. Snout to vent, 18.1; snout, 2.8; width of head, 7.3; length of head, 7.2; arm, 11.1; leg, 35.2; tibia, 11.4; foot, 15.

Variation. The series is very uniform in general characters, save that the dorsal pustular patterns may be dim. Females have smaller tympani, which are more or less oval, higher than wide—the longi- tudinal diameter about two-thirds of the eye, and its edge farther from the eye than in the males; the inguinal gland, and the parotoid glands, are usually smaller, and the latter a little less distinct than in the male. The size of the females in the collection is no greater than that of the males.

The closest relationship is apparently with M. hobartsmithi. The dorsal pattern of folds and pustules (tubercles) of that species is different; there is very great sexual dimorphism; the outer palmar tubercle is lacking; and the tibiotarsal articulation rarely reaches a slight distance beyond eye.

All the specimens were estimated to have been taken between an elevation of 7,000 and 8,000 feet. None were seen at lower eleva-

tions. All were taken on the ground among leaves. Three specimens of another small Eleutherodactylid were taken with these; they are believed to be the young of H. mexicanus. No adults of that form were taken. Microbatrachylus minimus sp. nov. (Plate LVI; figs. C, D)

A diminutive species (known maximum length for males, 15 mm.; for females, 19 mm.); head a little nar- rower than body, the eyes moderately prominent; eyelid (1.2 mm.) smaller than the interorbital distance (1.75 mm); tympanum large, subcircular, longer than high, its greatest diameter (2 mm.) equal to eye (1.95 mm.) ; distance between nostril and eye (1.83 mm.) greater than the distance of nostril to tip of snout (.95 mm.) ; snout rounded at tip, the length, 2.2 mm.

Tongue rather thick, rounded anteriorly and posteriorly the sides more or less parallel, free for more than one-third of its length; no vomerine teeth; choanae small, lateral, not or but partly concealed when seen from below; no vocal sacs.

Arm brought forward the wrist reaches near the tip of snout; tip of two outer fingers dilated into disks, with a terminal groove; the inner fingers not wider than digit; subarticular tubercles large rounded; fine supernumerary tubercles on palm; two large palmar tubercles, the median one largest; the outer entirely wanting; a row of tubercles under forearm; a distinct tubercle or swelling at the wristfold; arm more or less rugose; when legs are folded at right angles to body the heels barely touch; tibiotarsal articulation reaches to middle of eye; digits of second, third and fourth toes dilated with pads having a terminal transverse groove; subarticular tubercles strong; supernumerary tubercles on the foot almost obsolete, their location indicated by cream spots; inner metatarsal tubercle large, salient, about two-thirds the length of first toe; outer metatarsal

tubercle small, one-fourth size of inner; tarsus lacking an inner fold, three small, indistinct tubercles on the outer side.

A broken irregular fold runs back dorsolaterally, limiting lght dorsal coloration; region between very rugose and pustular, but no distinctive pattern can be discerned. A second broken fold runs on the side beginning above the tympanum; sides granular or tuber- cular as are eyelids; ventral disk well-developed, terminating on thighs; chin throat and all save posterior part of abdomen smooth; most of ventral surface of thighs smooth, but the strongly granular area in anal region encroaches somewhat on the ventral surface; inguinal gland rather indistinct (distinct in paratypes); a paro- toid gland above arm is not compact; a tubercle between arm and tympanum.

Color in life. Above dorsal surface light lavender, limited by the dorsolateral fold; the head lighter—the sides darker purplish (in aleohol the color becomes brownish), arms brownish-cream; lower arm and hand lavender, barred with purplish. Legs lavender barred with purplish; ventral surfaces cream with a peppering of pigment forming a very dim reticulation, enclosing rounded areas lacking pigment; lips with darker and lighter, more or less quadrangular spots; a dark bar from nostril, above tympanum and arm, becoming wider on side behind arm.

Measurements in mm. Snout to vent, 15; snout, 2.2; width of head, 5.3; length of head, 5.7; arm, 8; leg, 24; tibia, 7.6; foot, 9.8.

Variation. Most of the structural characters are constant; the skin is very rugose in all and occasionally a dim more or less distinct pattern is formed by the dorsal pustules. Usually two tubercles are present in the posterior part of the interorbital region. The largest specimen is a female and the colors are more intense.

Remarks. Two other forms of the genus occur in this region, albolabris and a form related to hobartsmithi. Further specimens of the latter will be necessary to determine its exact status. The speci- mens were all taken on the ground. The call is a weak chirp resem- bling an insect call more than that of an amphibian. These were heard both morning and late afternoon, as well as at night. I can- not distinguish the calls of the various forms.

Paratypes. EHT-HMS Nos. 21545-21554, 21556-21558, 21560- 21578; same locality and date; H. M. Smith and E. H. Taylor, col- lectors.

Diagnosis. A small hyla with a known maximum snout-to-vent length of 32 mm.; interorbital width one and three-fourths to twice the width of an eyelid; canthus rostralis distinct, lores sloping; greatest diameter of tympanum about two-thirds of length of eye; a slight axillary web; vomerine tooth groups lying between the an- terior ends of choanae; a very strong tarsal fold; heel brought for- ward reaches eye.

Description of the type. Head rather broad, with relatively small eyes, the distance between the orbits (4.2 mm.) nearly twice the width of an eyelid (2.15 mm.); length of eye (3.4 mm.) reaching anterior edge of nostril; distance between nostrils equals width of eyelid; snout a rather pointed oval with little or no depression be- tween nostrils; canthus distinct, but slightly rounded; lores sloping; the eyes seen from above extending beyond profile of jaw; tympanum distinct, the upper edge overhung by a slightly developed fold; tip of snout extending about 1.4 mm. beyond lower jaw; tongue about as wide as long, not or but very slightly notched behind, and with a very narrow free posterior edge; vomerine teeth in two transverse groups of six teeth, the anterior edges of the raised area extending slightly anterior to a line drawn between the anterior edges of the choanae; latter moderately large, oval.

Hand with rather large disks which are distinctly smaller than tympanum; outer digits half webbed or slightly less; first finger narrowed behind the disk; distal subarticular tubercles large, well- defined, that of outer finger single; proximal digits small; palmar tubercles tripartite, that on base of first finger elongate, not strongly differentiated; numerous indistinct tubercles or granules on palm; a row of tubercles under forearm; hind limbs relatively short, the tibiotarsal articulation reaching middle of eye; the heels overlap when limbs are folded at right angles to body; toes more than three- fourths webbed, the membrane reaching to near the disks; toe disks smaller than those on outer fingers; outer metatarsal tubercle large, distinct, rather diagonal in position; outer tubercle small, less dis- tinct; a very strong tarsal fold extends to heel, running slightly diagonally; anal flap short, rather narrow, with a slight median groove below it; skin on dorsal surfaces smooth; chin, throat and breast with dim, flattened granules; venter, sides and under side of femur strongly granular; a slight elevation behind eyes; axillary web distinct but small.

510 Tue UNIVERSITY SCIENCE BULLETIN

Color in life. Above, light olive green, lighter on side and above limbs; below flesh white; when preserved, the color is light flesh with a fine peppering of pigment some of which segregates to make minute flecks; a fine, equally distributed peppering of pigment on limbs, on both dorsal and posterior faces, visible under a lens; the eyeball is very black and seen through the eyelid make the eyelid appear black; a shghtly darker area or spot between eyes.

Measurements. Snout to vent, 31.2 mm.; length of snout, 5.1 mm.; snout to arm, 11 mm.; width of head, 11 mm.; length of head, 10.6 mm.; arm, 16.4 mm.; leg, 46 mm.; tibia, 15.5 mm.; foot, 20.8 mm.

Variation. Of the five adult’ paratypes three were colored like the type; two were purplish above save in the rump region, with a darker area on the tip of the snout; the darker area between the eyes is more pronounced in most of the specimens and there is slightly more pigment at the tip of the snout; some of the specimens have a slight depression between the nostrils; the smallest specimen measures 30 mm.; the largest, 32 mm.; the proportional measurements are very close to those of the type. All are females.

The young specimens taken at the same time differ from the adults in the shape of the head, the snout being shorter, and the tympanum is concealed. In life they vary from olive to leaf green, while some showed a purplish coloration above.

Remarks. All the specimens were taken from bromelias in the low trees growing along a small stream. The green and olive color- ation matched the green shades of the outer sides of the bromelias, while the purplish markings were similar to the purplish coloration of the inner basal parts of the leaves. Whether the males have vocal sacs or nuptial callosities is not known. I do not find saes present in any of the young, all of which are recently transformed. This is not conclusive evidence that this character is absent.

I am uncertain as to the relationship of this form. Two other Mexican Hylas are known to live in the bromelias—Hyla bromeliana and Hyla arborscandens. The latter differs in being a very much larger frog with yellow lateral spots; it has a sharper canthus ros- tralis and strongly defined nuptial callosities with minute nuptial spines on first and second fingers. From Hyla bromeliana it differs in having much smaller eyes, a wider interorbital region, and in the absence of the characteristic bands on the limbs.

Hyla arborescandens Taylor

Hyla arborescandens Taylor, Univ. Kansas Sci. Bull., vol. 25, July 10, 1938, pp. 388-391, fig. 1 (type locality 3 km. southwest of Acultzingo, Veracruz).

The type locality of this species was revisited on August 19 and 20, 1939, and a series of specimens were obtained from bromelias. The males agree with the type in having a rather sharp snout. The inner edge of the second finger has a row of minute spinules running to near the terminal pad, and occasionally spinules occur on the inner edge of the third finger. This character was overlooked in the type. The characteristic marking of the hind limbs is present in all the specimens, but more distinct in some than in others. The fold which runs from the eye, above the tympanum, terminates above the arm in a parotoid gland; a more or less distinct fold fol- lows the parotoid and this may be thickened and glandular; the interorbital distance is much larger than the width of the eyelid.

The two females in the lot are distinctly larger than males and both are filled with nearly ripe eggs. In one the color was dark olive to olive-brown above, with small, indistinct, darker areas above; and three or four yellowish spots along the sides; the other was light olive with a large quadrangular black spot on neck, with fine darker flecks scattered on back and dorsal surfaces of limbs. The snout is not pointed but somewhat truncate, and the lower Jaw is more rounded, and the nostrils are almost directly above edges of lip. The yellow spots on the sides are replaced with a fine, rather in- distinct reticulation.

Whether the eggs are laid in the bromelias or not I cannot say, but it is probable that they are. The breeding season would appear to be much later than that of Hyla miotympanum. Many of the tadpoles of the latter had already transformed at this time. In the numerous plants examined, no eggs or tadpoles were found. The snout to vent measurement of the largest male was 38 mm.; of the largest female, 49 mm.

Hyla erythromma Taylor

Hyla erythromma Taylor, Proc. Biol. Soc. Wash., vol. 50, April 21, 1937, pp. 48-50, pl. 2, fig. 1 (type locality, Agua del Obispo, Guerrero).

This species, discovered in 1936, was described from a single fe- male specimen. With the hope of obtaining more specimens in order to establish its legitimacy on a firmer basis, Dr. Hobart M. Smith and I revisited the spot where I had obtained the type. At a point about 200 meters from here in a rivulet arising from the Agua del

512 Tue UnNIversity ScieENCcE BULLETIN

Obispo spring I found six specimens of a small frog in a bush over- hanging the rivulet. They were calling, but the low voices could be heard at a distance of only a few meters. Doctor Smith ob- tained one in a tree some thirty meters farther up the stream.

On examination all of the specimens proved to be males and all had an extraordinary lateral gland extending nearly the distance between axilla and groin and reaching below like two closely pressed flaps on the abdomen. All had brownish-red eyes.

A comparison of these specimens with the type of erythromma leads me to the belief that they are the males of that species despite the differences that obtain. There is no evidence of the gland in the type. The skin is very smooth, while in the male specimens the skin is distinctly corrugated; the webbing between the digits is very slightly more extensive in the males; the lateral markings are more distinct and they are much more heavily pigmented above; the ventral part of the glands are yellowish with more or less dark pigment. The entire ventral part of the abdomen of the female is - lacking in pigment and it is entirely covered with large granules in- stead of only the area between the glands as in the males.

In life the males were largely green, or olive of varying shades. Certain of the specimens showed a brownish reticulation or mottling on the olive. The sides were cream, with spots, blotches or mottling of brown or olive. A diagonal cream stripe was present on the base of upper arm, while the axilla was cream. Below, the belly was creamy white to yellowish-cream. Some specimens had a few brownish spots on chin or throat and in front of the insertion of the arm.

That I am dealing here with two species is not beyond possibility. However, only larger series can settle the point beyond doubt. The small Hyla pinorum Taylor, also taken in this immediate locality in 1936, was not rediscovered, but there is no possibility of these specimens belonging to that species.

The first finger has a wider base than in the type and its dorsal surface is beset with a group of twenty to thirty black, horny spines, very much larger and not closely approximated as in such forms as Hyla lafrentzi, arborescandens and bistincta.

Top and sides of head and anterior part of body, black- ish-gray; posterior part of back shows very small, indistinct spots darker than the general color; dorsal surface of arms and fingers uniform dark; of legs and toes, mottled blackish-gray; belly and concealed surfaces of arms and legs, whitish; chin heavily pigmented with blackish-gray; under surface of knee dark; sides cream, with some dark reticulations and spots; undersurfaces of hands and feet more or less pigmented, posterior surface of thigh cream, strongly flecked and reticulated with darker color.

Measurements in mm. Snout to vent, 45; tip of snout to eye, 6.5; width of head, 14; length of head, 12; arm, 30; leg, 71; tibia, 22.5; foot, 33.5.

Remarks. Wacking knowledge of the characters of the males as pertains to the presence or absence of vocal sacs, and the nuptial armature of the first finger, I find it difficult to determine the re- lationship of the species. The presence of the arched anal fold is unique; the upturned face of the tympanic region (which does not appear to be due to distortion) is unusual. The size of the vomerine tooth areas is larger proportionally than in other known Mexican species.

In the type locality, Hyla arborescandens and Hyla miotympanum also occur. From the former it may be distinguished by the nar- rower interorbital distance, the larger eye and the smaller tympanum which is partly concealed. Hyla miotympanum differs from it in having a broadly rounded and flattened snout, the nostrils not

terminal; the lores are not vertical and the canthus rostralis is broadly rounded. The color in life was probably some shade of dark green above.

I take pleasure in naming the species for its discoverer, Mr. Dyfrig McHattie Forbes, of Potrero Viejo, Veracruz, my host on numerous occasions, who is an ardent collector and enthusiastic stu- dent of Mexican herpetology.

Hypopacuus Keferstein

Hypopachus Keferstein, Nachricht ges. Gottingen, 1867, p. 351 (type species, Hypopachus seebachii Keferstein = Engystoma variolosum Cope); Parker, A Monograph of the Frogs of the family Microhylidae 1934, p. 110. (See this paper for more complete synonymy.)

Parker’s monograph recognizes five forms of this genus, as fol- lows: (1) Hypopachus incrassatus Cope (Paraguay, 8. E. Bolivia, S. W. and N. W. Brazil; (2) H. inguinalis Cope (Guatemala) ; (3) H, variolosus (Cope) (Costa Rica); (4) H. cuneus Cope (Texas) ; (5) H. oxyrhinus Boulenger (Sinaloa, Jalisco, and Michoacan in Mexico; Guatemala). Since its publication, H. parkeri Wettstein has been described from Brazil; H. barbert Schmidt and H. glob- ulosus Schmidt from Guatemala.

Description. “Prevomer divided, the postchoanal portion absent; palatine absent. Clavicles and procoracoids present, almost straight, reaching the midline of the girdle and the scapulae; omosternum ab- sent; sternum cartilaginous. Vetebral column diplasiocoelous. Ter- minal phalanges simple.”

“Pupil round or rhomboidal. Tongue large, oval, entire and half free behind. Two smooth dermal ridges across the palate in front of the pharynx, the anterior much shorter than the posterior. Digits not dilated. In all the known species the tympanum is hidden, the first finger shorter than the second and the third toe longer than the fifth.” (From Parker loc. cit.)

Kellogg, 1932, treating of the Mexican species of the genus, gives only Hypopachus variolosus (Cope). He places H. oxyrhinus Boulenger as a synonym of variolosus.

He lists the type of H. oxyrhinus in the British Museum; three specimens in the U. 8. National Museum from Guadalajara and one from Arriba, Costa Rica (the latter probably properly associated with H. variolosus) and one from Ocatlan, Jalisco, in the American Museum of Natural History. While recognizing H. cuneus Cope as a legitimate species, he had seen no Mexican specimens of that species.

Parker, 1934, records H. oxyrhinus as follows: The cotypes (2) from Presidio de Mazatlan, Sinaloa; 1 specimen, San Salvador,

516 THe UNIversITy SCIENCE BULLETIN

Michoacan, 2,500 ft.; 1 specimen, Buena Vista, Michoacan, 2,000 ft.; 1 specimen, Cofradia, Michoacan, 700 ft. He lists a half-grown specimen in the Mus. Vienna, from Coban, Vera Paz, Guatemala.

The material on which the present report is based consists of more than 250 specimens of the genus and 6 species and subspecies are recognized. The localities are scattered widely in the Republic. No specimens are known from the northern or eastern two-thirds of the plateau. On the plateau it is confined to the southwestern region. It occurs in lowlands everywhere except to the northwest, in northern Sinaloa and Sonora. The genus is unknown in Baja California.

Groups of specimens from Chapala, and Zapotiltic Jalisco; and Queseria, Colima; offer certain problems, and require further study. A part of these from the west coast belong to H. oxyrhinus Boulen- ger. I wish to acknowledge the aid of Mr. H. W. Parker of the British Museum for his kindness in examining specimens.

Hypopachus cuneus cuneus Cope (Plate LXII, fig. A; Plate LXIII, figs. 7, 7a)

Hypopachus cuneus Cope, U. 8. Nat. Mus. Bull., No. 34 1889, pp. 388-889, fig. 98 (type description; type locality ‘‘San Diego in Nueces County,” Texas).

This species, originally discovered on the extreme northern border of its known range, has been traced some distance into the eastern coastal region of Mexico. The following specimens are present in the collection: EHT-HMS Nos. 1094-1097, near Forlon, Tamaulipas, Mexico, August 4, 1934; H. M. Smith-David Dunkle collectors. These are the first recorded specimens from Mexico. Aside from the Mexican specimens the following Texas specimens have been available: EHT-HMS Nos. 1032-1033, 18 mi. S. E. Rio Grande City, Texas, September 6, 1932, Taylor and Smith; K. U. Nos. 9886- 9891, San Diego, Duval county, Texas, July 3, 1930, Taylor; K. U. No. 9885, Cameron county, Texas, July 3, 1930, Taylor.

This subspecies is distinguished by the almost complete loss of the digital web on foot in both sexes; relatively shorter legs; small hands and feet; absence of any clearly defined reticular pattern on the ventral surface.

Tongue free for about half its length. Anterior dermal ridge (fold) slightly curved; posterior ridge followed by parallel dermal folds running longitudinally; on each side laterally, in older speci- mens, these folds may begin on a level with the posterior edge of the anterior ridge; choanae large, when seen from ventral view,

TAYLoR: HERPETOLOGICAL MISCELLANY 517

nearly two-thirds of the openings concealed by an overhanging shelf. Male with vocal sac.

The coloration of the Mexican specimens is an indefinite olive. The pattern on the back consists of an inverted V, on the shoulders; the two sides of the latter then continue back parallel for a short distance then diverge to the groin. This figure is outlined with a series of more or less distinct, irregular black dots or spots; a row of similar spots begins behind eye and continues to groin. The area between this and the median pattern is a trifle lighter than color within the figure. The groin has one or two irregular ocellated darker spots which may extend on the proximal dorsal and anterior face of femur as a continuous or broken stripe; femur, tibia and foot each with bands or dots of black which tend to form a continu-

No. 1094 has a very fine light tan reticulum scarcely discernible on ventral surface. The chin is powdered with cinnamon.

No. 1097 is yellowish-white with no trace of markings; arm with traces of bands. The hair fine median line is present; in all there is also a trace of a median line on chin and throat, and one beginning above anus follows an irregular course back of the femur and tibia on the heel. One specimen from Brownsville and one from San Diego shows more lateral spotting which encroaches somewhat on the abdomen; light line behind and below eye not black bordered

Hypopachus cuneus ngroreticulatus subsp. nov. : (Plate LIX)

Type. EHT-HMS, No. 12605, adult female, Encarnacion, Cam- peche, Mexico; collected by Hobart M. Smith, October 1, 1936.

Paratypes. EHT-HMS, Nos. 12594-12604, 12612, 12614-12655, Encarnacion, Campeche, October 1-10, 1936; 12656-12674, 12675- 12690, Encarnacion, Campeche, October 11-14, 1936; 12606-16611, Tres Brazos, Campeche, September 19, 1936; 12691, Pital, Cam- peche, October 16, 1931; 12613 Chichen Itza, Yucatan, August 25, 1936—all collected by Hobart M. Smith.

Diagnosis. Related to Hypopachus cuneus cuneus, but differs in having the markings on the throat of a different character from those on abdomen; a heavy black reticulation covering abdominal region and underside of limbs; sides of body black with yellow spots or reticulations; dorsal surface of upper arm light, usually cream color and dorsal part of femur with a light ground color, cream or pinkish cream in life.

Description of the type. Snout narrow, pointed, its anterior out- line oval when seen from above; canthal region rounded, the sides of the snout slightly oblique, with a very slight depression in loreal region; snout projects beyond the mouth nearly half its length; eye large, 4mm. in length; length of snout, 2.3 mm.; eye to tip of snout, 3.9 mm.; eyelid, 2.1 mm.; interorbital width, 4mm.; snout to occipi- tal fold, 5.6 mm.; tongue broad, rounded behind, free for more than half its length. Palatal ridges distinct, the anterior shorter than posterior, slightly curved; second higher, broader, transversely longer than the preceding ridge; behind the second the derm is ar- ranged in longitudinal, plicate folds, which at sides push forward along the end of the second ridge; choanae large, but when viewed

TayLtor: HerrpPerotocicaL MIscELLANY 519

directly from below the overhanging ridge conceals three-fourths of the openings; openings of the Eustacian tubes half as large as choanae, placed opposite the posterior edge of the first dermal ridge; fold across the occiput moderately distinct; fold across chin well defined; fold on breast not distinguishable; a thickened fold from eye to arm, bordered by a deep groove; this groove is intersected by the one from the chin fold, which crosses the Jaw angle at a point some distance behind the eye.

Arm moderately long, brought forward, the hand extends beyond the snout; three well-developed palmar tubercles, the median extend- ing more forward than other two, outer largest, inner smallest; second and fourth fingers extend an equal distance forward, reaching the anterior edge of the distal subarticular tubercle of the third finger; first finger reaches only as far forward as the proximal tubercle of the third finger.

Leg brought forward the inner metatarsal tubercle reaches at least to the posterior corner of eye; when legs are folded at right angles to the body the heels are separated by five millimeters; outer metatarsal tubercle more than half as large as inner, narrowly sepa- rated from inner; latter with its greatest length distinctly less than length of the first toe, compressed, strongly elevated; outer tubercle much less elevated; no web between digits (a trace only in males).

Color. Above nearly uniform lavender-brown, slightly more olive in dorsolateral region; the dorsal pattern obsolete, evidenced only by an H-shaped group of black dots above shoulders; a hair-fine line from tip of snout to above anus; a dark stripe from tip of snout to groin, broken more or less on sides; area on side of head below eye slightly pigmented and a white or cream stripe present from eye to insertion of arm; dorsal face of limbs light, remainder with dark spots, stripes or reticulations; a group of spots on posterior part of back and inguinal region; a rather large black inguinal spot; bars on dorsal surface of legs represented by small black spots; under surface of feet, except tips of toes, dark; chin dull lavender with a very fine lighter reticulation; belly cream with a heavy black reticu- lation; a hair-fine line from tip of chin to breast, and from its pos- terior end two broader cream lines run forward to arm insertions.

Variations. Most of the differences observable are those due to age. One or two very young specimens have the ventral reticulation dim; in some specimens the typical (generic) dorsal pattern is rather clearly defined and is outlined with darker. The dorsal ground color varies through grays, gray-browns, lavenders, to reddish purple; the

520 THe UNIVERSITY ScIENCE BULLETIN

ventral color is whitish to cream; the ventral reticulation varies from dark gray to deep black. The single specimen from Chichen Itza, Yucatan, has the dorsal surface an immaculate, dark lavender with a single groin spot; no dorsal limb markings; throat deep lavender with fine lighter flecking; and the ventral reticulation of the abdomen is very dim. Males have a vocal sac, and have small tubercles scattered on dorsal surface of body and limbs; tubercles also present on chin and on lateral edges of digits.

Measurements in mm. Snout to vent, 43.4; snout length, 2,3; head width, 13; head length, 11.3; arm, 23.1; leg, 49; tibia, 16; foot, 22.8.

Remarks. It is a surprising fact that more than ninety-five per- cent of this large series of specimens are females; in the other species of Hypopachus, I have from Mexico, the males strongly predominate.

Hypopachus ovis sp. nov. (Plate LXII; fig. B)

Type. EHT-HMS No. 1050, adult male, collected at Tepic, Nayarit, Mexico, July 31, 1934, by E. H. Taylor.

Paratypes. EHT-HMS Nos. 1034-1049, 1051-1098, topotypes; same data.

Diagnosis. A small species, known maximum size 36.5 mm., with a dorsal pattern clearly defined; sides dark with small cream spots; limb brought forward the inner metatarsal tubercle fails to reach eye; males with toes one-fourth to one-fifth webbed, the web con- tinued as a slight fringe on side of digits; width of eyelid about half of interorbital distance; snout projects but little beyond mouth; skin above roughly corrugated; males with fine, pearly tubercles on dorsal and lateral surfaces, posterior face of leg, on chin and lateral digital fringes. Venter grayish with dim, lighter spots.

Description of the type. Snout narrow, pointed, projecting some- what beyond the mouth; canthal region rounded, lores oblique, with a distinct depression between nostril and lower part of eye; line of mouth does not reach as far posteriorly as the back of eye; snout projects beyond mouth scarcely more than one-third its length; eye, 3.5 mm. long; snout, 2.9 mm.; eye to tip of snout, 3.1 mm.; eyelid, 2 mm. wide; interorbital width, 3.5 mm.; snout to occipital fold, 5 mm.; tongue elongate, free for half its length; anterior dermal ridge on palate separated from posterior by 1.4 mm.,; posterior ridge wider and transversely longer, followed by longitudinal plicae which push up farther forward at ends of ridge; openings of eustachian tubes round, about one-half the area of the choanae, which are elongate and when viewed from below, are nearly half concealed by the over-

TayYLorR: HERPETOLOGICAL MIscELLANY 521

hanging shelf; openings of eustachian tubes are opposite the space between dermal ridges; a strong dermal fold passes across head and down to about lower level of eye then passes back to near insertion of arm, the skin of the fold being much thickened laterally and preceded by a groove; a vertical groove crosses near angle of jaws, but cannot be traced across chin; no chinfold and no fold across breast. Skin of breast and anterior abdominal region thickened, into an abdominal glandular area (not so in females) ; skin of the dorsal surface strongly rugose, the summits of the small pustules each surmounted by a pearly tubercle on all dorsal surfaces, very few on head; a few tubercles on chin and along the lateral edges of digits; arm moderate, brought forward the hand extends beyond the snout; three palmar callosities, the two outer largest, the median ex- tending more forward than other two; fourth finger extends slightly farther forward than the second, neither extends beyond the distal tubercles of the third finger; inner metatarsal tubercles fail to reach eye when leg is brought forward; metatarsal tubercles more or less compressed, the length of the inner distinctly less than distance between tubercle and end of first toe, longer than free part of first toe; toes one-fifth to one-fourth webbed in males (less in females), the web continued as a narrow fringe for some distance along the sides of the digits, the edge surmounted by a row of spinelike tuber- cles.

Coloration. Above brown with a median darker pattern edged with black, beginning between eyes and extending back in a sym- metrical pattern to posterior end of body; sides lavender-brown, darker than adjoining region of the back, with small cream flecks; lower on sides, larger, rounding, cream spots; femur and tibia crossed by a black-edged stripe, continuous when leg is folded; arm with some darker areas and a light area on the dorsal surface of upper arm; chin grayish-black (males) ; abdomen, breast, and under side of limbs with a reticulum of lavender pigment enclosing lighter areas so sparse that the abdomen appears nearly white; posterior face of femur and tibia, brown with cream spots; under surface of hands and feet lavender, except tips of digits and the metatarsal tubercles which are cream.

Variation. The large series is uniform in most structural charac- ters and in size. There are slight differences in proportion as shown in the table of measurements.

Remarks. The series was obtained at night in the environs of Tepic in a small pasture. Most of the specimens were calling from tiny puddles of water that had formed in hoofprints.

Hypopachus alboventer sp. noy. (Plates LX, LXIIL; figs. 3, 3a)

Type. EHT-HMS No. 18615; eight miles east of Cuernavaca, Mor. June 20, 1938. E. H. Taylor coll.

Paratypes. EHT-HMS Nos. 6552-6555, km. 133, near Huajintlan Mor. July 14, 1936; 18611-18614; 18616-18621, two to eight miles north and east of Cuernavaca, June 17-20, 1938. E. H. Taylor.

Diagnosis. A medium sized species, maximum known length 44 mm. ( 9 ); males with a well-defined glandular region on breast ex- tending onto abdominal region, the posterior border definite; absent in females; toes nearly half webbed, in males the membranes some- what excised, the toes bordered almost to tip with dermal fringes;

Taytor: HrrprerotocicAL MIscELLANY 523

female with toes about one-fourth webbed; length of inner tubercle four-fifths of the inner toe; venter cream white without reticulation or ocelli; dorsal pattern somewhat similar to H. ovis, but lacking ventral markings with more web on feet in males. Limb brought forward, tibiotarsal articulation reaches about to arm insertion, the inner metatarsal tubercle fails to reach eye.

Description of type. Snout narrow, short, truncate, extending be- yond line of mouth, the nostrils almost terminal; loreal region sloping vertically; canthus rostralis indistinct rounding; length of eye (3.1 mm.) minutely longer than snout; diameter of nostril large con- tained in its distance from eye about two and one-half times; width of an eyelid (2.3 mm.) less than half of the interorbital width (4.8 mm.) ; no trace of tympanum; a strong fold from corner of eye to arm; another fold passes across jaw angle and across the throat; line of mouth does not reach back as far as posterior corner of eye.

Tongue elongate, free for half its length, nearly as wide posteriorly as anteriorly; anterior palatal ridge distinct, separated from the larger posterior ridge by a distance equal to half its length; posterior ridge higher, prominent, followed by regular plicae; choanae large, at anterior end of buccal cavity, concealed almost completely by upper jaw when seen from below; hand with large subarticular tu- bercles; three palmar tubercles, that on base of first finger smallest, median largest, placed farther forward than other two. Legs short, the tibiotarsal articulation reaches to near arm insertion; when folded at right angles to body, heels separated by from four to five millimeters; toes about one-third webbed; the dermal fringes on toes narrow, inconspicuous; subarticular tubercles rather small; no su- pernumerary tubercles; inner metatarsal tubercle very large, strongly salient, the inner free edge somewhat compressed, the outline seen in profile forms a half circle; outer metatarsal tubercle smaller, its free edge pointing anteriorly, a little more than half size of inner and separated from it by a space less than half its length.

Skin thick rugose; the pustules, small, distinct rather flattened on back and sides, arms smooth; proximal part of the posterior face of femur with fine pearly spines; a few on dorsal surface of tibia; ventral face of femur with a few, large, flattened granules; a slight fold behind eyes; head quite smooth; anterior face of femur and tibia smooth.

Color. Deep purplish lavender above with a black edged, darker area extending from behind eyes to back of body, widening gradu- ally, the outer edges irregular; the black border of this area crosses

524 Tue University ScreNcE BULLETIN

the limbs, making a continuous line when limbs are folded; an in- conspicuous inguinal, dark spot; chin and throat with a heavy pep- pering of lavender-brown pigment; belly rather cream with a fine peppering of pigment discernible under a lens; tips of digits and the tubercles pure cream; heel, soles and palms purplish; posterior face of femur lavender with some blackish reticulation; a very tiny white line on fold back of mouth angle.

Measurements of type and paratype (No. 18619 3) in mm. Snout to vent, 44, 37.8; snout length, 4, 3.2; width of head, 13.8, 13.4; length of head, 9.8, 10; arm, 26.5, 22.5; leg, 50, 46; tibia, 15.8, 15.2; foot, 25.2, 24.

Variation. The type series is constant for the general structural characters; the dorsal marking may be more distinct than type or almost obsolete; males differ in having a fairly well-defined thick- ened glandular area on breast which exudes a viscous fluid that dries into a rubberlike sheet. It probably serves to assist the male in clasping the female. The feet of the males have much more webbing and the dermal fringes are usually distinct to the narrow tips of the toes. The edges of the digits are beset with minute spinules of pearl color; a few scattered spinules on back, sides and venter; those on posterior face of femur are absent; most of the specimens have a deep purplish spot back of eye; the chin is bluish black in males. The call is a rather high pitched bleat that is from two to two and a half seconds in duration.

Remarks. This form may be separated from its congeners by the greater webbing on the feet and absence of a reticulated or ocellated pattern on venter. Specimens were obtained at night. Their call suggests the call of a small lamb or kid. Often they would call from the edges of pools where they had burrowed into the earth leaving only small openings to the outside.

Type. EHT-HMS No. 1023; near San Ricardo, Chiapas, Mexico, September 2, 1935; E. H. Taylor and Hobart M. Smith colls.

Paratypes. EHT-HMS Nos. 1016-1022; Asuncion, Chiapas, Mex- ico, September 1, 1935, Hobart M. Smith and E. H. Taylor.

Diagnosis. Related to alboventer but differs in having the sides and posterior part of body spotted with black; a fine median dorsal line; a diagonal cream line behind the eye; body more elongate in proportion to width; eye larger in proportion to length of snout.

TayLtor: HeprPrrotocicaAL MIscELLANY 5yA5)

Toes of males nearly one-third webbed; venter cream-white un- spotted. Known maximum size, 41mm. ¢@.

Description of the type. Adult female; head width (11.6 mm.) greater than length, (9.2 mm.); very heavy fold across head behind eye, continued to arm; a groove crosses jaw angle and passes across the throat; eye length (4mm.) greater than length of snout (2.9 mm.); width of an eyelid (2.2mm.) slightly more than half the interorbital width (4.1mm.); choanae very large, not more than half concealed by jaws when seen from below; tongue without pig- ment (true also of alboventer). Anterior dermal palatal ridge twice as long as its distance from the posterior; latter ridge followed by dermal plicae; which also reach forward on each side of the ridge; (vocal sacs in males).

Three palmar tubercles, the median largest extending forward be- yond other two; subarticular tubercles large; no supernumerary tubercles. When leg is brought forward the inner metatarsal tu- bercle reaches. anterior corner of eye.

Toes less than one-fifth webbed, the web continued on sides of toes as narrow dermal fringes (nearly one-third webbed in males) ; inner metatarsal tubercle with a compressed edge, the outline not semicircular, its greatest length a little longer than its distance to tip of inner toe; outer metatarsal tubercle about half size of inner.

Skin with small pustules, not strongly defined (more so in some paratypes) ; a few indistinct granules on posterior part of femurs; male with minute spinules on pustules, on toe edges and on chin.

Color. Above purplish brown with an irregular row of spots from eye along side to groin; some scattered darker areas on back, num- erous spots on lumbar region and groin; a double, black line crosses femur and tibia; arm faun with some small black spots; dorsal part of femur faun; tibia lavender; posterior face of femur faun, heavily spotted with black; below uniform cream (males with black throat) ; lip ight lavender; a cream line from eye to foreleg.

Remarks. The series of measurements given of the type series, show the variations in proportions; the photographs of the two paratypes give the variations in markings.

The specimens were collected while Doctor Smith and I were en- route to Tuxla Guterriez, from Tonola. About nightfall we arrived at a small stream near Asuncidn, and finding it flooded, we were forced to spend the night at that place. We utilized the delay to good advantage obtaining the types of this species and good series of several other species during the night.

blackish stripe from snout to groin, continued on front of femur. It differs from other forms in having the tongue pigmented, often forming blackish areas or spots; toes one-fourth (or a little less) webbed; a dark inguinal spot; venter cream with a deep, black- brown reticulation.

Description of the type. Width of head (14mm.) much greater than length (9.2 mm.); eye (4mm.) longer than snout (2.5 mm.) ; width of an eyelid (2.4 mm.) less than half the interorbital distance (4.1mm.); distance between eye and nostril (2mm.) greater than distince between nostril and snout tip (1.2mm.); a fold back of eyes crossing head and continuing back on side of neck to arm inser- tion; a fold passing across angle of jaw and throat; angle of mouth not extending back as far as eye; no trace of tympanum; tongue elongate thick anteriorly, thin behind, feebly nicked posteriorly, free for nearly half its length; pigment on tongue forming a large dim, median area, terminating in two spots posteriorly; choanae large, not more than half concealed by overhanging shelf from upper jaw; anterior palatal ridge distinct, slightly curved; posterior ridge higher, thicker, followed by plicate folds; openings of the vocal sacs very distinct; arms rather long, the wrist reaching beyond snout; first finger shorter than second; latter about equal to fourth; three palmar tubercles, the median rather small (in paratypes, larger than outer) and extending farther forward; edge of fingers with minute, pearly spinules (wanting in females); leg short, the heels separated (by 6mm.) when limbs are folded at right angles to body, heel reaches to a point above arm, and the anterior edge of inner meta- tarsal tubercle reaches to nostril; toes about one-fourth webbed, the web continued somewhat as narrow dermal fringes; inner metatarsal tubercle very large, its length minutely less than that of first toe, its free outline forming a half circle; outer tubercle more than half the size of inner, both tubercles compressed and with a free edge; skin above minutely corrugated, without pustules or granules; very slight evidence of granulation on sides; a few flattened, indistinct tubercles below anus.

Color. Above lavender-brown, with an irregular series of streaks and small spots of black forming diagonal line which connects with a black inguinal spot; and which, when limb is folded, crosses femur, tibia and foot as a broad, blackish band with a light line or spots within its borders; a broad, black stripe from snout to groin and along front face of femur, the upper edge clearly defined by a lighter border; upper arm ‘cream above, dark anteriorly and pos-

A single female specimen, EHT-HMS, No. 12692 ¢ was col- lected by Doctor Smith in Tres Brazos, Campeche, September 19, 1936. Its size suggests a young animal as its snout to vent mea- surement is only about one-half that of the largest known specimen.

Head rather pointed, strongly projecting (1.1 mm.) beyond mouth; eye (1.6 mm.) in length of snout (2.1 mm.) 1.3 times; eye to tip of snout, 2.56 mm. (in the type, the snout is twice the diameter of the eye) ; eanthal region rounded, very slightly concave in front ~ of eye; a strong skin fold across head behind the eyes, which passes down on side and is dimly traceable back toward the insertion of the front leg, and from eye back it is bordered by a groove; a groove crosses posterior part of jaws and is visible on sides of chin; nostril much nearer tip of snout than eye; width of an upper eyelid (1 mm.) in interorbital distance, 2.3 times. Tongue large, free behind for nearly half its length; anterior dermal ridge slightly curved, sep- arated laterally from raised, rounded areas by a narrow distance; second ridge transverse, crenulate, behind which the derm is ar- ranged in parallel longitudinal folds; openings of the Eustachian tubes opposite the raised rounded areas, small, about one-third the diameter of a choana; latter large, when observed from a ventral view, more than two-thirds of the opening is concealed by an over-. hanging shelf. (Males with a vocal sac.) Pupil of eye round.

Limbs well-developed, the arm reaches beyond the snout; the

TAYLOR: HERPETOLOGICAL MISCELLANY 529

hind leg brought forward along the sides of the body, the tibiotarsal articulation reaches eye, the metatarsal tubercle reaches the tip of snout; three flat, palmar tubercles on hand, the median extends farther forward than the other two; fourth finger a little longer than second, reaching the second outer subarticular tubercle; first finger short, reaching anterior edge of the subarticular tubercle of the second, tubercles only slightly raised. A slight, indistinct, inner metatarsal tubercle; first toe reaches posterior edge of tubercle on second toe; second toe reaches to anterior end of the proximal tubercle of third toe; third toe to the distal tubercle of fourth; fifth toe slender small, failing to reach the medial tubercle of fourth toe; apparently no trace of web (a rudiment in males); when limbs are bent at right angles to body, the heels touch.

Color and markings. Brownish lavender above; a stripe on side of snout, and from behind eye, continues dimly to groin; an inguinal black spot. A single, broad, black-edged stripe crosses femur, tibia and heel. A triangular dark spot involves anus; an hourglass- shaped dark spot begins near eyes and disappears near middle of back; chin with a fine distribution of pigment enclosing small irregular cream spots; belly cream or whitish, with a more or less regular reticulum of dark pigment; a few darker spots on knees; undersurface of hands and feet pigmented, including tubercles; a light spot on tip of snout.

Measurements in mm. Snout to vent, 18; to arm, 7; axilla to groin, 8.5; tip of snout to fold of head, 3.8; width of head to groove on jaw, 5.1; arm, 9.8; leg from anus, 26.5; femur, 8; tibia, 8; foot from heel, 13.

Remarks. This small species remains rare in collections. There are three, including the type from Veracruz in the British Museum, and a single specimen in the University of Michigan collected in Guatemala.

A few slight differences are in evidence between northern (Kansas) specimens and southern (Mexican) forms, but these differences seem to break down where large series are available. I can see no con- stant differences between Texas specimens and those from Coahuila and Durango.

Description of species. From EHT-HMS No. 1194, Torreon, Coah., adult female. Head triangular; general habitus very stout (female with eggs); eye small (2.4 mm.), shorter than snout (2.9 mm.) ; distance of eye from anterior tip of snout, 3.2 mm.; eye to nostril, 1.9 mm.; eyelid (1.3 mm.) contained in interorbital width (3 mm.) 2.3 times; snout to occipital fold 4.7 mm.; snout extends beyond mouth 1.5 mm.; snout rounded, the canthus not distinct; lores oblique with only a slightly concave region. The anterior dermal fold on palate shorter than posterior and separated by a distance about equal to the width of the anterior; openings of the eustachian tubes small, less than a fifth as large as the very large choanae; a line drawn between the openings of the eutachian tubes passes anterior to the anterior dermal fold; more than half of choanae visible when viewed directly from below; tongue large, rounded a little in front, flattened behind, free for a little less than half its length.

Skin smooth save for numerous tubercles on posterior face of femora on either side of anal region; a curving fold crosses the head and runs back to arm, the fold thickened laterally; a groove crossing the angle of the jaw can be traced a short distance on chin.

Arm brought forward the hand extends beyond snout; palmar tu- bercles large, flat; fourth finger longer than second; subarticular tubercles large rounded; leg brought forward, the inner metatarsal tubercle does not reach eye; when legs are folded at right angles the heels touch (or sometimes slightly overlap) ; inner metatarsal tuber- cle relatively small, its length contained about twice in its distance from the tip of the first toe; toes not or but slightly flattened, no lateral fringe or only a faint trace of a dermal fringe on toes; male with a vocal sac.

Color. Above olive-brown in alcohol, usually more olive in life; a few very small, darker, rounded spots on dorsal surface; the dor-

TAYLoR: HERPETOLOGICAL MISCELLANY 531

sal pattern, as such, is wanting; a few dark flecks arranged in an - irregular row behind eye, and one between eyes; below immaculate; very slight pigmentation under chin, some on under side of the feet and hands, not visible save under a lens.

Variation. Males differ from females in having small pearl-colored tubercles scattered on the back, eyelid, dorsal surface of tibia-fibula, dorsal and posterior part of foot, on edges of fingers and a semi- circular patch around the edge of lower jaw; occasionally a few scattered ones back of the femur near anus—but never as numerous or as prominent here as in females.

In color the markings vary from nearly uniform olive specimens to specimens with still more numerous black spots than in the de- scribed specimens. The colors range from gray to brown. One or two specimens have a median dorsal dark pattern, bordered by the darker spots. Males have a dark infusion on the chin, due to the pigmentation of the vocal sac lining. In specimens of equal head- body length there is some variation in size of foot and also slight variation in the relative lengths of the fingers and toes. The largest male specimen (No. 1234) from Conejos, Durango, has somewhat more pigment on throat and breast and on the underside of hands and feet; the toes seem slightly flattened and there is a faint indi- cation of a web. Since the lining of the mouth is somewhat loose the relation of the openings of the eustachian tubes and the dermal folds varies somewhat.

Remarks. 'These specimens extend the known range into the states of Coahuila and Durango, a distance of about three hundred miles.

Aside from the specimens already listed I am associating with this species three specimens which may be specifically distinct from this form. I collected the specimens, Nos. 1236 @ , 1238 9 , and 1237 2, at Mazatlan, Sinaloa, July 20, 1934, at an elevation less than ten meters above sea level. The specimens are dark brown, with an irregular, more or less continuous dark line beginning a little behind eye and continuing along the side for some distance beyond arm. Anal region of female less papillate; eye a little smaller and snout narrower and extending a little more beyond the mouth than in equal-sized specimens from Durango and Texas.

The three specimens are small and indifferently preserved. I have hesitated to describe the form as new without a more adequate series of specimens. The largest specimen, a female, measures 25

mm. snout to vent, but is adult containing eggs; the largest male measures 23 mm.

Leptotyphlops magnamaculata sp. nov.

Type. U.S. N. M. No. 54760, Utilla Id., Honduras., F. J. Dyer, collector. (The specimen is a female containing two eggs.)

Diagnosis. A small, lined species (length, 167 mm.) with a large cream spot involving much of rostral, edges of nasals and the pre- frontal. Rostral but little less than half width of head, supraoculars present, two labials; scales 14 rows; 233 dorsal scales; terminal scale wedge-shaped.

Text Fic. 1. Leptotyphlops magnamaculata sp. nov. Type. USNM, No. 54760; Utilla Island, Honduras. (> 11.)

Description of the type. Rostral large, a little less than half width of snout, slightly narrowed between nostrils, extending back between eyes but not reaching their posterior level; nasals separated by the prefrontal, which is much smaller than the supraoculars; latter widely separated from first labial, reaching to very near edge of eye above; anterior parietal very broad, in contact with second (last) labial; posterior parietal (occipital) wide, shghtly narrower than the preceding, separated from the second labial by a single scale; nasal completely divided, the superior nasal wider and longer than inferior nasal, considerably narrower than the rostral at its widest point; first labial small, not reaching as high as the inferior nasal, reaching as high as eye but not level of pupil; the labial border of first labial larger than that of inferior nasal; eye very large, raised slightly, pupil distinct; the labial border of ocular slightly less than second labial; ocular slightly narrower than the

TAYLOR: HERPETOLOGICAL MISCELLANY 533

rostral; four lower labials, last largest, completely concealed when jaw is closed; six scales, as well as the median mental, which is grooved but not divided, border upper labials when mouth is closed; scales from rostral to tail spine about 233; scales under tail, 17; head scales with minute rugosities; if epidermis is shed, these appear as pits on scales.

Color. Color above, deep, dark brown, forming continuous lines; ~ below only slightly lighter brown, the edges of all scale rows lined with creamy white. The four dorsal light lines are widest and run from head to near tip of tail, each occupying space on edges of two scale rows; the line between the fifth and sixth rows is almost obso- lete and the brown coloration here forms a band nearly two scales wide; the lines between the fifth and fourth and the fourth and third scale rows are more pronounced than the preceding and are some- what zig-zag; lines between third and second, second and first are less contrasted. Head brown, with a prominent cream spot on snout covering rostral, prefrontal (internasal) and parts of the upper nasals. The lower part of ocular and the posterior upper labial have an irregular cream area. Ventral edges of the rostral, nasal and first labial, as well as the lower labials and chin are light with more or less pigmentation. Tip of tail including about four transverse scale rows, clear cream.

Measurements. Total length, 167 mm.; tail, 10.4mm.; width of head, 2.5mm.; width of body, 3.7 mm.; tail length in total length, 16.7 times; diameter of body in total length, about 45 times.

Remarks. This species, related to phenops, is differentiated by the size of the frontal cream spot and the lower number of ventrals; the body is apparently wider in proportion to length and the rostral is wider, and the terminal spine is somewhat vertically wedge-shaped.

I presume it is a derivative of phenops that has differentiated in an island habitat.

Leptotyphlops rufidorsum sp. nov.

Type. U.S. N. M. No. 49998, Lima, Peru. Townsend, collector.

Diagnosis. A large (265 mm.) species lacking white or yellow spots on snout and tip of tail, and lacking lineated dorsal markings. Supraocular very large, in contact with (or narrowly separated from) first labial. Two labials. Total dorsal scales, 268; 14 scale rows. Tail in body length, 22 times; body width in length about 61 times. ;

Description of the type. Rostral broad, (1.85 mm.) slightly less than one-half width of head (3.85 mm.), somewhat tongue- shaped,

parietal is separated by a single scale; frontal smaller than either prefrontal or interparietal; median scales following the interparietal smaller than adjoining scales; four lower labials, the fourth largest and completely concealed; when mouth is closed, six scales appear to border the upper labials, the last three separated from the labial border by the fourth labial. Scales in fourteen rows anterior to anus; on tail ten rows. Anal large; first subcaudal much wider than succeeding scales. Total dorsal scales from rostral to tail spine, 268; subeaudals 17.

Color in alcohol. The three median dorsal scale rows and the ad- joining half rows on each side reddish-brown with only slight in- dication of darker centers; remaining rows creamy white; the spine is distinctly darker than remainder of tail (perhaps nearly black in life).

Measurements in mm. Total length, 265; tail, 12; width of head, 3.85; width of body, 4.3.

Taytor: HerprrrotocicaL MisceELLANY 585

Remarks. The relationship of this species with other South American forms is a bit uncertain. It is widely separated from albifrons by absence of lineated pattern, terminal yellow spots and about 78 more transverse scale rows; from goudoti in having the nasal completely divided; from affinis by having the first labial rel- atively narrow and in contact with the supraocular; from bilineata, macrolepis, myopica and bressoni by having only two labial scales; from humilis, dugesii and septemstriata in having supraoculars; from bakewelli and phenops in the type of color and markings and absence of contact between labial and supraocular; from dimidiata it differs in having a large supraocular touching the labial; the tail is contained in total length 22 instead of 14 times; from maximus and dulcis by the very large supraocular and higher number of scales; from borrichiana in having the supraocular touching the first labial.

Leptotyphlops nasalis sp. nov.

Type. U.S. N. M-No. 16134, Managua, Nicaragua.

Diagnosis. A form lacking supraoculars, their space occupied by the superior nasal rather than by the oculars; no prefrontal; fourteen scale rows. Rostral elongate, reaching behind posterior level of the eye; two labials present; dorsal scales, 253; tail, in total length, 14.6 mm.; diameter of body in total length, 55 times.

Description of the type. Rostral but little more than one-third width of head, tongue-shaped, narrowed a little between the nostrils, extending back considerably behind posterior level of eye, in contact with the frontal; nasal divided completely, the superior nasal greatly

elongated, extending farther back than the rostral; superior nasal somewhat narrower than the rostral, slightly narrower than the ocular; anterior parietal very large, broadly in contact with the last (second) labial; second parietal (occipital) narrower, separated from the last labial by a single seale; only first pair touches the frontal, which is as large as the interparietal; prefrontal wanting; first labial narrow, reaching to lower level of eye but not as high as the pupil, separated from the second labial by the ocular. The labial border of the inferior nasal less than that of the first labial; labial border of ocular much larger than that of preceding scales but less than that of the second labial; four lower labials, the outer largest, concealed (when mouth is closed, six scales border the upper lips); eye distinct, rather large, more than half the width of an ocular; eye and pupil distinct; about 253 scales from rostral to terminal caudal spine; 21 scales under tail; 14 scales around body; 10 seales around tail.

Measurements. Snout to vent, 110 mm.; tail, 7.6 mm.; diameter of body, 2 mm.; tail in total length, 14.6 mm.; diameter in length, 55 times.

Color in alcohol. Above light brown, the color lighter on the ventral surface (may be discolored somewhat by preservation); a small cream spot on rostral beginning near anterior end of snout, but not reaching anterior level of eye. On the tail the spine alone is cream.

In the dorsal coloration there is some slight segregation of the pigment but trace of the lineation such as is present in bakewelli or phenops is wanting.

Remarks. The curious elongation of the nasals, the absence of supraoculars and a prefrontal, easily distinguish this species from any of the other known species.

A medium-sized, heavily pigmented species, showing no trace of dorsal lineation; large supraoculars present, widely sepa- rated from the labial, broadly in contact with the rostral; two labials; eye moderately distinct, rostral lacking trace of terminal cream spot; terminal spine cream; fourteen scale rows; tail in total length, about 18.9 times; width of body in total length, about 60 times; 259 scales snout to vent.

TayLtor: HERPETOLOGICAL MISCELLANY 537

Description of the type. Snout rather truncate anteriorly; rostral somewhat less than one-half width of head at widest point, the part above rather tongue-shaped, extending distinctly behind the pos- terior level of the eye, broadly in contact with the supraoculars; prefrontal absent; frontal small, equal to interparietal, a little more than half the size of the supraoculars; anterior parietal large, wider than posterior parietals, broadly in contact with the last (second) labial; the posterior parietal separated from labial by a single scale; nasal completely divided, the lower part small, much narrower than upper part; first labial barely reaching lower level of the eye which is moderately distinct; part of rostral on under side of snout slightly

narrower near the nostrils; the labial border of the ocular a little larger than that of last labial; the labial border of first labial small, about equal to that of the inferior nasal; three lower labials on right, four on left side; six scales border the upper labials when the mouth is closed.

All the head scales have tiny rugosities which appear as pits when epidermis is removed; scales in 14 rows to anus; 10 about tail; 259 dorsal scales between rostral and terminal spine; anal large, single; 17 subcaudals, the three rows under tail much widened; eye large, moderately distinct.

Color in alcohol. Blackish-brown to blackish above; ventral sur- faces a lighter brown, the terminal spine cream; scales bordering mouth whitish, showing some unpigmented areas.

Measurements. Total length, 185 mm.; tail, 9.8 mm.; width of body, 305 mm.; width of head, 2 mm.

Remarks. ‘This species is possible related to bakewelli, despite the fact that it lacks a rostral cream spot and lineated markings on body. The relation of the frontal and the supraoculars are similar in the two species; the other Central American species having an elongate rostral (Leptotyphlops nasalis) lacks the supraoculars and the space occupied by the supraoculars is occupied by the superior nasals. This species lacks the lineated markings.

Siagonodon dugesit Bocourt, Etude sur les reptiles, Mission Scientifique au Mexique et dans l’Amérique Central, Livr. 8, 1882, pp. 507, 508, pl. XXIX, fig. 9, 9a, 9b, 9c; and pl. XXX, fig. 4 (type description; type locality, Colima, Mexico, A. Dugés collector).

This species has remained very rare in collections. Three speci- mens in the U. 8. National Museum belong to this form: No. 26140 “Mexico,” A. Dugés; No. 48537, Guanajuato, A. Dugés; No. 49632 Talpa, Jalisco, Nelson and Goldman. The last specimen has been badly dried and broken. The others are in a fair state of preserva- tion, save that they are badly faded.

The relationship of this form is probably with Leptotyphlops humilis (Baird and Girard), but I am not prepared to admit that the relation is subspecific. The total count of scales from rostral to terminal plate is 231 and 244 in the specimens mentioned above; there are 18 scales under the tail. In both cases the anal is entire (divided in one of the two cotypes). The head is more truncate than in humilis and the median scales following the rostral have straight transverse edges. The prefrontal is much larger in dugesi.

The coloration of the U. S. N. M. specimen is badly faded. Bo- court says of the types, “Une teint d’um jaune roussatre, légerement carminé, est répandue sur toutes les régions supérieures du corps. Les parties inférieures sont d’un jaune rosé.”

Text Fic. 6. Phyllodactylus lanei Smith. Showing arrangement of tubercles (granular scales on body are depicted too small). (Much enlarged.)

Certain specimens in the collection referred to P. lanei by Smith proved to belong to a different species. Smith (loc. cit. p. 128) notes the difference in these specimens from typical lanei. The specimens in question are 1181-1183 Organos, Guerrero; 1499-1501

542 Tue UNIVERSITY SCIENCE BULLETIN

from Agua del Obispo, Guerrero, and 534, 535 and 741 from Mazat- lan, Sinaloa.

Smith obtained a series from Hda. El Sabino, Uruapan, Michoa- can, which I refer to P. lanet (EHT-HMS Nos. 10877, 10943-10994). This lot is especially uniform as regards significant characters. Each of the paired chinshields is in contact with two labials (in 99 out of 102 times). Counts on the number of scales between the middle of the orbits (not at narrowest point between orbits as counted by Smith) showing the following: The number 12 occurs in three speci- mens; 13 in thirteen specimens; 14 in twenty-three specimens; 15 in fourteen specimens; and 16 in three. Between the orbital edge and edge of eyelid there are usually three rows of granules and the palpebral row bordering the edge. In about 62 percent of the speci- mens there is an enlarged scute directly above the orbit. In other specimens the scale may be present on one side only or absent on both sides.

I obtained a series of this form in Guerrero in 1936 at the follow- ing localities: 11034, 11010, 11014, El Treinte; 10998, 10999, 11001- 11006 near Palo Blanco; 11068 Tierra Colorado; 11012-11013 Puerto Crucita, north of Acapulco; in 1938, Nos. 16315-16316, Pie de la Cuesta, and 16317 near Xaltinanguis. These specimens do not show any appreciable departure from limits described by Smith for the species, when the specimens mentioned above are excluded.

Phyllodactylus delcampi Mosauer

Phyllodactylus delcampi Mosauer, Copeia, No. 3, November 15, 1936, pp. 141-144, figs. 1-6 (type locality, Tierra Colorado, Guerrero).

This species may be easily differentiated by the absence of en- larged tubercles on the tail and on the dorsal and posterior surface of the femur; by the large size, with very small dorsal tubercles; and by the transverse dark or black bands on the body. The upper eyelid is apparently more ample than in the other known Mexican species of Phyllodactylus, and the pigmentation of the venter is usually somewhat more dense.

Six specimens (EHT-HMS, Nos. 18956-18961) were obtained at the type locality in 1938. Five of these were collected at night and are very much lighter than the types. One, No. 18959, preserved in the daytime is equally as dark as the type. The number of scales between middle of orbits (not counting eyelid scales) is 20-24. Five scale rows form a whorl on tail, the posterior series a little larger usually than the other four. In two cases the postmentals are sepa- rated by the mental, in four they are together. In four cases eight

Taytor: HERPETOLOGICAL MISCELLANY 543

scales follow the postmental, in two five. In two cases the post- mentals each touch one labial; in two cases they touch two; in two, on one side, they touch one, while on the other they touch two. Usually there are twelve to fifteen scale rows between the ventral scales and outer row of tubercles. Anteriorly on the body the tuber- cles are in seven rows on each side, while posteriorly there are five rows on each side. :

I have examined the types.

Phyllodactylus homolepidurus Smith

Phyllodactylus homolepidurus Smith, Univ. Kansas Sci. Bull., XXII, No. 6, April 15, 1935, text fig. 1A and plate XXV, fig. 2 (type description; type locality five miles southwest of Hermosillo, Sonora).

No new specimens of this species have been collected. This form may be distinguished from the southern P. lanei by the very small pair of slightly enlarged scales on each tail segment, often so small as to be indistinguishable (as is true in the type) ; in the large num- ber of scales between orbits (counted between the middle of orbit rather than the narrowest point) ; in the fact that chinshields usually touch only one labial; in the lack of the enlarged scales on orbital border; in the greatly reduced number and size of enlarged tubercles on dorsal part of the femur or their total absence.

The number of scales between the orbits varies between 19-24, the numbers 20, 21, 22 being equally common, the other counts are repre- sented by one or two examples each; the tubercles on the dorsal part of the body are smaller and less salient than in P. lanei, and it is a somewhat smaller species.

From muralis it differs in coloration and markings; in having smaller, less conspicuous tubercles on the back; in the greatly re- duced number or absence of small tubercles on the dorsal side of the femur. The tail is never so plump, and the scales do not form such distinct regular rows on the tail segments. It is a somewhat larger species.

Variation. The normal expectation is for each chinshield to touch one labial only (90 times, one, 23 times, two). Frequently the con- tact with two labials occurs on one side only. The scales bordering the chinshields are not greatly enlarged; however, there is a single median scale or a pair of median scales that are larger than the rest. The total number varies between six and nine, six occuring three times; seven, seventeen times; eight, thirty-two times; and nine, seven times. The occipital region is covered with granules similar to those on the back, with larger, rounded seales intermingled with them. The tail is constricted, rather distinctly at the base, more so in females than in males. The seales on the dorsal part of the upper arm are cycloid, imbricating, though somewhat thickened, in fe- males; in males the seales are more or less trihedral and raised. The tubercles are very slightly larger in males. A few specimens show dorsal spots arranged in indefinite rows. A more or less defi- nite line extends from the snout to the forearm along the side of the head. The tails are broken in every specimen, suggesting that this member is extremely fragile. The tails at the base are somewhat brownish with indefinite darker spots. In some specimens the pairs of enlarged scales on the tail are less strongly differentiated from the other scales of the tail than in the type.

Remarks. Most of the specimens were taken on walls at twilight and after dark. The specimens of the species are very numerous at Totolapam.

In the reduction of the enlarged scales on the tail and the pos- terior part of the femur this form approaches homolepidurus more than it does lanez.

Phyllodactylus magnatuberculatus sp. nov.

Type. EHT-HMS No. 10995, Acapulco, Guerrero, Mexico, Oc- tober 10, 1936, H. M. Smith.

Diagnosis. Characterized by very large heavy tubercles on dorsal surface in 14 rows, the outer rows smaller; scales between middle of orbits 17; scales of occiput as large generally as those between eyes with slightly larger scales intermingled on the temporal and occipi- tal regions bordering the keeled or trihedral tubercles, all smaller than those on back. Those on nuchal region larger, but likewise smaller than those on back; larger trihedral scales on dorsal surface of femur intermixed with small, unequal-sized granules, the im- bricate scales confined to anterior faces of femur; dorsal surface of upper arm with heavy trihedral tubercles placed closely together;

a pair of chinshields broadly in contact with two labials, and in turn bordered behind by four scales, the two median largest forming transverse sutures with the paired chinshields; base of tail with six heavy tubercles on first annules. Scales bordering anterior part of ear cavity, large, triangular, pointed.

Description of the type. Head moderately deep, its greatest length (20mm.) is 1.5 times the greatest width (13.3 mm.); snout from orbit, 8mm.; ten large scales between orbit and nostril; twenty-five scales across snout between the fourth labials; scales on snout rather large anteriorly, rounded, low, while in front of orbits, bordering a median elongate depression the scales are compressed conical, or somewhat trihedral; rostral nearly twice as wide as high; a single pair of internasals their suture with rostral, anterior to level of nos- trils; nostril surrounded by rostral, first labial, an internasal and two postnasals, the upper largest; evelid covered with three rows of granular scales and an outer row of superciliaries, anteriorly en- larged, flat, quadrangular, posteriorly strongly spinose; about seven enlarged upper labials, posterior small the suture between the sixth and seventh directly below the vertical pupil; five lower labials to the middle of eve followed by about three shghtly enlarged scales; a few enlarged tubercles border the minute labials near angle of mouth. Mental elongate its labial width a little more than four- fifths of its length (3.5 x 4.15 mm.) ; chinshields in contact for about one-third their length; scales following chinshields are symmetrical forming straight transverse sutures with chinshields, each separated from labial by one scale.

A lateral fold present which is thickened with fatty tissue; gran- ules on back between tubercles much smaller than (one-third) size of scales on occiput; scales on anterior surface of upper arm en- larged and thickened, gradually becoming trihedral or pyramidal on the dorsal surface, with a few small granules between them; fore- arm granular dorsally with trihedral or pyramidal tubercles; scales on anterior surface of arm larger, imbricating, on ventral surface small granular; scales on ventral surface of abdomen, cycloid, juxtaposed, showing some denticulation on posterior edges; ventral and anterior face of leg with cycloid, imbricating scales; dorsal and posterior face with granular scales; dorsal surface of femur with about 12 large conical or trihedral tubercles; femur and foot (to a lesser extent) with strong trihedral tubercles; terminal lamellae of digits widened and elongated the outer anterior edges angular rather than rounded; a pair of scales at base of the widened terminal

lamellae; under toes and fingers the lamellae may be single or paired, sometimes divided in three; claws retractile in a sheath above terminal lamellae; reproduced tail broken, but the basal segment has three heavy tubercles on each side of the first annulus.

Color in alcohol. Above yellowish-gray with a scattering of pig- ment; a few elongate dim spots visible along the back near median line; below immaculate vellow (under strong lens some pigment can be discerned).

Measurements in mm. Snout to vent, 66; snout to ear, 17.3; snout to arm, 26.5; axilla to groin, 30; arm, 20; leg, 24; head length, 20; head width, 13.3.

Relationship. The closest relationship appears to be with Phyl- lodactylus lanei from which it differs chiefly in the larger tubercula- tion of the back, the heavier tubercles of the upper arm, proportion- ally thicker head and the vellow coloration.
