C. : AT $1.75 PER COPY (CLOTH) IL ADVERTISEMENT The scientific publications of the National Museum consist of two series—Proceedings and Bulletins. The Proceedings, the first volume of which was issued in 1878, are intended primarily as a medium for the publication of original papers based on the collections of the National Museum, setting forth newly acquired facts in biology, anthropology, and geology derived there- from, or containing descriptions of new forms and revisions of lim- ited groups. A volume is issued annually or oftener for distribution to libraries and scientific establishments, and, in view of the impor- tance of the more prompt dissemination of new facts, a limited edition of each paper is printed in pamphlet form in advance. The dates at which these separate papers are published are recorded in the table of contents of the volume. The present volume is the sixty-fifth of this series. The Bulletin, publication of which was begun in 1875, is a series of more elaborate papers, issued separately, and, like the Proceedings, based chiefly on the collections of the National Museum. A quarto form of the Bulletin, known as the “Special Bulletin,” has been adopted in a few instances in which a larger page was deemed indispensable. Since 1902 the volumes of the series known as ‘‘ Contributions from the National Herbarium,” and containing papers relating to the botanical collections of the Museum, have been published as Bulletins.

By R. A. Sr. Grorar, Of the Bureau of Entomology, United States Department of Agriculture. INTRODUCTION. The present paper gives a revised systematic characterization of the larvae of the subfamily Tenebrioninae; discusses a suggested close relationship between the larvae of this subfamily and those of the Blaptinae; it enumerates and gives a detailed account of the larvae of the genera of Tenebrioninae which are present in the National Collec- tion, it further discusses LeConte’s old genus Meatus, and gives a generic key. In conclusion it has a general morphological descrip- tion of the hitherto undescribed larva and pupa of Merinus laevis. (Olivier). Family TENEBRIONIDAE. The larvae of the family Tenebrionidae were characterized by Schiddte, 1879.1 The characterization is still applicable, and comparatively few additions and changes in the original diagnosis are needed in spite of the great number of new larval types described since Schiddte’s work was published. The following family diagnosis is therefore to be considered as a mere translation of his Latin text with some of the original descrip- tive terms modified to suit the modern nomenclature and with a few new characters added and other slightly changed.? FAMILY CHARACTERIZATION. Tarsus and claw fused into a single, unguliform article.

Second and third pairs of mouthparts retracted, with large, plicate, moderately con- vex maxillary articulating area. Clypeus distinctly separated. Labrum large, (nearly) covering the mandibles. Antenna inserted behind mandible, lateral, hardly longer than mandible, triarticulate ; membrane connecting antenna with acetabulum protruding, joint- like. Mandible with molar part robust, cutting part bi-ortridentate, ventrally excavate. Maxilla covered by mandible; cardo large, tri- angular; stipes well developed, broad; cardo and stipes connected with submentum by maxillary articulating area; maxillary mala single, obtuse (or acute), pectinate; maxillary palpus not much longer than mala, triarticulate, with annular basal membrane. Labial palpus short, conical, biarticulate; stipites labii concrete. Mentum large, (normally) barrel-shaped, free; submentum large, trapezoidal, connected with maxillary articulating area. Gula simple, (normally) quadrangular. Ligula small (acute or obtusely pointed), bispinose (or multispinose). Abdomen prolonged, ninth segment terminal with pygidium extending over anal segment. Anal segment short, (sometimes) with two projecting and retractile ambulatory warts (verrucae). Spiracles annular, open, with a single respiratory slit. Subfamily TENEBRIONINAE. The family Tenebrionidae is divided by modern systematists into a great many subfamilies; Leng’s catalogue of North American species records 22 subfamilies. Investigation of the larve seems to substantiate the correctness of this classification, which is based entirely on characters from the adults. However, the three main sections into which Schiddte divides the larvae can be considered only to a limited extent equivalent to three series of our subfamilies. Thus his first main section corresponds roughly to the subfamilies Scaurinae, Blaptinae, and Opatrinae; his third main section is equivalent to the subfamily Alleculinae; while his second main sec- tion represents at least five subfamilies. Among these is the sub- family Tenebrioninae (created by Gebien, 1910), with which the present paper is particularly concerned. The Tenebrioninae are represented in Schiddte’s work by only one genus, namely, Zenebrio, but in the National Collection there are some 13 genera referable to the subfamily and the representation in our collection of the other Tenebrionid subfamilies has increased proportionally. It is therefore obvious that Schiddte’s group char- acterizations are no longer adequate, and in this paper the writer is attempting the needed recharacterization only of the subfamily Tenebrioninae. The other subfamilies, however, have been studied as far as available larval material permitted. ART, 1 LARVAE OF AMERICAN TENEBRIONINAE—ST. GEORGE. 3 The morphological structures here examined are those which Schiddte discussed in his-conspectus and upon the different develop- ment of which he formulated his diagnoses. It was due entirely to a lack of sufficient material when Schiddte’s conspectus was formu- lated that it is now antiquated. His methods of research, however, and his sound judgment are still unsurpassed. SUBFAMILY CHARACTERIZATION. Mandible with the back opposite the cutting edge, without mar- gination * and excavated opposite the molar part; without membra- nous elevation *; apically bifid or trifid; with or without additional dorsal tooth between apex and molar part. Ocelli* arranged in two transverse, crescent shaped or circular groups on each side of head, and with five more or less fused lenses; or with only opthalmic spots which vary from being distinct to vanishing. Antenna‘ with basal article distinctly longer than wide. Labrum dorsally without trans- verse, densely setose elevation. Leg with claw falcate, enlarged at base on exterior side. Pygidium apically bicornute, or without cerci and with side margins sharp and bearing short spine-like setae. Anal segment with or without projecting and retractile ambulatory warts (verrucae). Abdominal spiracles oval and transverse. AFFINITIES BETWEEN THE SUBFAMILIES TENEBRIONINAE AND BLAPTINAE. The value of the subfamily diagnosis of the Tenebrionidae as given above, depends more on the exact combination of the char- acters chosen than on a very special and exclusive development of the single characters; hence the diagnosis is formulated with rather liberal allowance for considerable variation in most of them. In this connection it is interesting to notice that through a series of genera these structures show a gradually increasing similarity to the corresponding structures in the genera Blaps, Eleodes, and E'm- baphion, which constitute an entirely different subfamily, namely, the Blaptinae. In the genera Xylopinus, Haplandrus, Polypleurus, Iphthimus, Alobates, and Glyptotus, which represent the most typical forms of the subfamily Tenebrioninae, the left mandible has a trifid apex (@?, a*, a*, fig. 832) and an additional tooth (¢) on the dorsal side near apex; the right mandible is also trifid (a+, a?, a°, fig. 33) but lacks the additional tooth (¢) between the apex and molar part. In U/pis, 8 Except Rhinandrus and Zophobas, which have slight marginations and membranous elevations. In small immature larve the ocelli are more prominent and the proportions o antennal articles variable. In Scotobates the basal article is nearly as wide as long and the second article is long and globose. +4 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. Merinus, and Scotobates the mandible has changed slightly; both right and left mandibles are still apically trifid but both lack the additional dorsal tooth. (Figs. 2 and 5.) A still further modifica- tion of the mandible takes place in Coelocnemis and Tenebrio, which show the beginning of the mentioned affinity to the Blaptinae. In this subfamily the left mandible is bifid with a dorsal tooth near the molar part, and the right mandible is bifid with a dorsal tooth near apex. Moreover the back of the mandible has a slightly developed carinate edge opposite the cutting part, and opposite the molar part a well developed completely exposed membranous elevation with either a few rather strong setae arranged in groups anteriorly and posteriorly, or with many scattered, rather short and rigid setae. Compared with these structures in Blaptinae, we find in Coelocnemis each mandible bifid at apex, the left with an additional dorsal tooth near the molar part, the right with a tooth near apex (¢, fig. 54). In this particular development, all species of Tenebrio are identical with Coelocnemis. In the latter genus (fig. 54) and the two species, Tenebrio molitor and Tenebrio obscurus, there is only one seta an- teriorly and two setae posteriorly on the dorsal side of the back of the mandible (fig. 51) but in Tenebrio picipes (fig. 53) the setae are scattered and numerous as in some genera of the Blaptinae. Finally, the genera Zophobas and Rhinandrus demonstrate quite strongly the suggested affinity of the Tenebrioninae with Blaptinae, possessing in addition to the characters of Coelocnemus, Tenebrio molitor, and Tenebrio obscurus, a slight margin on the back opposite the cutting edge and also a membranous elevation opposite the molar part, two characters which do not occur in the other Tenebrioninae. In Zo- phobas the margin on the back of the mandible is rounded (c, fig. 62) while in Rhinandrus it is sharp (ce, figs. 60 and 61) which is also typical of the Blaptinae (figs. 64 and 65, H'leodes). The setae on the anterior part of the membranous elevation are not as numerous in Zophobas and Rhinandrus as in the Blaptinae, but otherwise we find the whole structure developed exactly as in this subfamily. In the typical Tenebrioninae the pygidium is bicornute at apex with side margins rounded, and either without setae, or with setae arranged in a transverse series in front of the cerci. (Figs. 36, 41, and 45.) In Jenebrio molitor and Tenebrio obscurus it is apically bicornute, but with side margins sharp and with two short, spinelike setae on each side near apex. (Figs. 49 and 50.) In Zenebrio picipes the apex is acute, not bicornute (fig. 52) and side margins are sharp but with many setae, bearing a striking resemblance to the pygidium of Eleodes tricostata. (Fig. 63.) In Zophobas and Rhinandrus the pygidium is apically obtuse, without cerci and with side margins sharp and bearing two short spinelike setae on each side near apex. ART. 1 LARVAE OF AMERICAN TENEBRIONINAE—ST. GEORGE. 5 (Figs. 56 and 57.) This form of pygidium shows a strong resem- blance to that of Hleodes opaca (figs. 66 and 67) and Eleodes car- bonaria (fig. 68). In regards to the size of the anterior legs, as compared with that of the second and third pairs, the Tenebrioninae show considerable variation. In Haplandrus, Scotobates, and Tenebrio the first pair of legs are only slightly larger than the second and third pairs so that all legs appear to be nearly of the same size (figs. 47 and 48) ; but in Polypleurus, Coelocnemis, Glyptotus, Xylopinus, Ipthimus. Upis, Merinus, Alobates, Zophobas, and Rhinandrus the first pair of legs are strong and robust, and the second and third pairs rather suddenly decrease in size (figs. 17, 22, 34, 35). This difference is greatest in Rhinandrus (figs. 58 and 59), less in the other genera, increasing slightly according to the sequence in which they are men- tioned. In this character Zophobas and Rhinandrus are close to the Blaptinae. The ocelli also differ somewhat in arrangement and prominence within the subfamily. They are arranged in two transverse, cres- cent shaped or circular groups. In prominence they may vary from being distinct to vanishing or apparently wanting. The various ocelli on each side of the head may be represented in the ocellar groups either by lenses, more or less fused, or only by pigmented spots which may be either distinct or indistinct. In one Central American species® in the national collection, apparently closely related to Coelocnemis, five distinct ocelli are present in two trans- verse groups and the lenses are separated and protruding. In Upis and AMerinus the ocelli in each of the groups are without spaces be- tween the lenses and less protruding. In Scotobates, Iphthimus, Haplandrus, Glyptotus, and Tenebrio the divisions between the lenses can not readily be seen and the latter are almost fused to- gether, so that each group of ocelli appears more or less as a single large ocellus. This is particularly the case in Z7’enebrio, where the two ocellar groups appear as two single ocelli and are so described by Schiddte. In Alobates, Coelocnemis, Rhinandrus, and Zophobas, the ophthalmic spots vary from being present to vanishing. By con- sidering the ocelli as two groups, even when each is fused into what appears to be a single ocellus, we can include all genera of the Tenebrioninae in our characterization. In the Blaptinae the ocelli are evanescent. The abdominal spiracles are oval and transverse in all genera ot both Tenebrioninae and Blaptinae. 5 Labeled: ‘‘ Cacao, Trece Aguas, Alto Verapaz, Guatemala, collected April, 1906, by E. A. Sehwarz.” 6 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. From the foregoing it is apparent that Rhinandrus and Zophobas more closely resemble the Blaptinae than do any other genera of the ‘Tenebrioninae. In fact the only consistant character separating them from the Blaptinae is the absence of any transverse, densely setose elevation on the labrum, a character present in all Blaptinae and absent in all Tenebrioninae. | GENERA OF SUBFAMILY TENEBRIONINAE. Of the 23 genera of the subfamily Tenebrioninae in the United States, which Leng® recognizes, larvae of the following 13 were available for study: The genus Polypdelurus Eschscholtz, of which there are three species, is represented by germinatus Solier. The material consists of a larval skin and a reared adult. The larva was found by the author in a decayed oak twig at Falls Church, Virginia, July 25, 1918, and reared September 7, 1918. Material of the genus RAinandrus LeConte consists of several larvae, larval skins, a pupa, pupal remains, and reared adults of sublaevis Horn. The larvae were taken by H. G. Hubbard from the nest of a rat (Neotoma albigula) in Tucson, Arizona, during the period from January to June, 1897, and reared by T. Pergande. Doctor Schwarz states that it is very difficult to separate the adults from those of Alobates sublaevis (Beauvois), and he was at first in doubt as to which genus they belonged. He has not had an oppor- tunity to examine the types. The larvae of these two genera, how- ever, can be easily separated by the characters given in the key. On the other hand, the larvae of Hubbard are hard to separate from Zophobas, closely allied to Rhinandrus. For this reason Doctor Schwarz, like the writer, feels quite certain that the above-mentioned material is referable to Rhinandrus. The genus Zophobas Blanchard contains only one species (morio Fabricius). A larval specimen was collected by E. A. Schwarz in the canal zone of Panama, February, 1911. Doctor Schwarz is not positive of the determination, but from a comparison of the char- acters of this with the closely allied Rhinandrus sublaevis, the writer feels quite certain that the determination is correct. Another larval specimen, collected by M. A. Palmer, in a cave at Guana Jay, Cuba, May 5, 1900, is very closely related to this genus. The genus Scotobates Horn, consisting of two species, is repre- sented in the national collection by calcaratus (Fabricius). Since this is one of the most abundant species in the eastern part of the ®Leng, C. V., 1920, Catalogue of the Coleoptera of America, North of Mexico, pp. 218-219. The names of Leng is followed throughout in discussing the material repre- sented under each genus. ART, 1 LARVAE OF AMERICAN TENEBRIONINAE—ST. GEORGE, 7 United States, it is well represented. Many of the specimens have been reared. The genus Merinus LeConte is represented by its only species, laevis (Olivier). The material, associated with reared adults, con- sists of several larvae and pupae collected by the writer near Falls Church, Virginia, July 23, 1918. The rest of the larval material, not associated by rearing experiments, consists of the following specimens: one larva taken by H. S. Barber from a dead branch in the top of a cherry tree at Occoquan, Virginia, July 4, 1908; a second larval specimen taken from beneath the bark of a dead maple tree at Dead Run, Virginia (opposite Plummer Island, Maryland), Feb- ruary 17, 1915 (H. G. Champion, collector) ; and a third specimen taken by the writer from under chestnut bark at Black Pond, Fair- fax County, Virginia. The genus Xylopinus LeConte is represented by both its species, saperdioides (Olivier) and aenescens LeConte. The material con- sists of several specimens of saperdioides associated by rearing, as follows: larval skin (larva taken by A. B. Champlain from a de- cayed sycamore tree at Harrisburg, Pennsylvania, April 7, 1913, and adult reared June 10, 1913); several larvae taken by F. C. Craighead from the heartwood of a dead, dry oak log at Great Falls, Virginia, May 30, 1916 (pupa collected with these transformed June 8, 1916) ; and several larvae taken by F. C. Craighead from beneath the bark of a decayed oak log near Great Falls, Virginia, May 25, 1919 (adults reared June 4, 1919, from part of the same collection). The material representing the species aenescens, consists of two larval skins; one of larva taken by T. E. Snyder from beneath the bark of a decayed oak at Shipman, Virginia, October 11, 1913, and from which adult was reared May 28, 1914; another of larva taken by T. E. Snyder at Black Mountain, North Carolina, March 22, 1913, which pupated April 15 and transformed to imago May 9, 1913. The genus Haplandrus LeConte, of which there are three species, is represented by fudvipes (Herbst). The material associated by rearing consists of the following specimens: Four alcoholic larvae and one larval skin, the latter from a specimen which pupated May 15 and issued May 23, 1913, all out of a collection of five larvae taken by A. B. Champlain from a dead white pine at Charter Oak, Penn- sylvania, April 10, 1913; and ten alcoholic larvae and one larval skin, the latter from a specimen which was reared through to adult April 16, 1914, all out of a collection of eleven larvae taken by E. A. Schwarz and H. S. Barber in a dry trunk of redbud at Plummer Island, Maryland, August 27, 1913. Of the material not associated by rearing there are several specimens taken from a rotten oak at Plummer Island, Maryland, by Messrs, Schwarz and Barber. Other specimens were collected as follows: Larval skin and adult taken by 8 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. R. C. Shannon from an oak log at Dead Run, Fairfax County, Vir- ginia, August 6, 1915; and a larva collected by C. G. Marshall at Silver Hill, Maryland, February 22, 1916. An undetermined larva, closely related to the genus Haplandrus, was taken by H. S. Barber at Brownsville, Texas, who suggests that it may represent a species belonging to the Mexican fauna. The genus Coelocnemis Mannerheim, of which there are five species, is represented by dilaticollis Mannerheim. The material con- sists of two larval specimens, not associated by rearing, collected by D. W. Coquillett in Los Angeles County, California. The rest of the material is without specific determination and consists of two larvae taken by H. S. Barber from under stones at Williams, Arizona, between May 30 and June 8, 1901; one larva taken by E. A. Schwartz from the ground at Oracle, Arizona, July, 1898; and a third larval specimen taken by Schwarz and Barber from Cacao trees at Aguas Alta, Verapaz, Guatemala, April, 1906. The genus 7phthimus Truqui, consisting of three species and three varieties, is represented by serratus (Mannerheim) and its varieties. The material representing the variety swblaevis Bland consists of: Larval specimens found in Pinus ponderosa at El Paso County, Colorado, February 26, 1914 (A. B. Champlain, collector), from a larva taken with them an adult was reared July 3, 1914; two larval specimens, not associated by rearing, taken by E. A. Schwarz and H. S. Barber at Williams, Arizona, during June, 1901; and a third larva taken from the decayed part of a telephone pole above the ground, on the Montgomery to New Orleans line, during August, 1921. The remaining specimens of the species serratus, not associated by rearing, were collected as follows: One larva from a decayed log in a Tamarack swamp at Detroit, Michigan (H. G. Hubbard, collector) ; a second larva taken at Field Brooks, California, May 19, 1903 (H. S. Barber, collector) ; and a third larval specimen from a sycamore log at Smith Point, Texas, November 15, 1918 (H. S. Barber, collector). One other larva, determined as /phthimus species, was taken by H. G. Hubbard from a decayed log at Hood River, Oregon, May 21, 1892. The material representing the variety lewist Horn consists of four larvae taken together with adults, from under the bark of a tree at Lake Tahoe, California, July 8, 1891 (H. G. Hubbard, collector), and three pupae and one adult taken by F. G. Schaupp at Kelly, New Mexico, July, 1890. The genus Alobates Motschulsky, of which there are three species, is represented by pennsylvanica (De Geer). As this species is very common in the eastern part of the United States there are many speci- mens of it. The larval material, of which part is associated by rear- ing, has been taken mainly from beneath the bark and in the outer ART, 1 LARVAE OF AMERICAN TENEBRIONINAE—ST. GEORGE, 9 sapwood of maple, oak, chestnut, tulip, and sycamore trees. Adults of this species usually emerge about the first week in July. A single larval specimen, collected by D. W. Snyder at Luebo, Congo, Africa, appears to be closely related to this genus. The genus Glyptotus LeConte, containing the single species cribratus LeConte, is represented by only one larval specimen. It was taken by H. S. Barber from a dead limb of a palm tree (7hri- nax) on Big Pine Key, Florida, March 6, 1919. This specimen was determined by the writer, by locality, by comparison with size of adult and by a process of elimination of larval characters. Doctor Schwarz states that the species erébratus is about the only one there of its size and that it occurs in large numbers. The genus U/pis Fabricius is represented by its only species ceram- boides Linnaeus. The reared material consists of several larvae which were taken by S. A. Rohwer from beneath the bark of a dead white birch tree at Trout Lake, Wisconsin, September 23, 1913. Some larvae of this lot of material were caged September 27 and from them an adult emerged July 3, 1914. Of the material not associated by rearing experiments there are several larvae which were taken by H. G. Hubbard on the shores of Lake Superior, Michi- gan, July, 1876; and one larva taken from a decayed log by the same collector at Hood River, Oregon, May 21, 1892. The genus Z'enebrio Linnaeus, of which Leng recognizes the three species obscurus Fabricius, molitor Linnaeus, and picipes Herbst, is well represented by material from various parts of the United States and a few specimens from Europe. Part of the material from this country has been reared. The larval habits of the two first-mentioned species are interesting in view of the fact that they have so many hosts. Besides being found in stored grain, they have also been found in a nest of Bombus, débris of a flying squirrel’s nest, in 7?gridia, in roots of Althaea, and in hydrolyzed sawdust, which was being fed to cattle. The material representing picipes Herbst consists of the following: Larva and adult taken from a rotten log at Rockville, Pennsylvania, November 13, 1913 (H. B. Kirk, collector) ; three larvae and two adults found in nest of Bombus at Detroit, Michigan, probably in July, 1876 (H. G. Hubbard, collector) ; and a single larval specimen collected “on strawberries” at De Queen, Arkansas, March 26, 1921 (J. W. Berg, collector). * DISCUSSION OF LECONTE’S OLD GENUS NEATUS. It may have been realized from the comments in the preceding dis- cussion that, in the little group of species which are included under the genus 7’enebrio Linnaeus, the species picipes Herbst occupies a position distinctly separate from the more typical forms, molitor 10 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. Linnaeus and obscurus Fabricius. This is largely due to differences in structures exhibited by the larvae. These can be briefly summa- rized as follows: Setae on the dorsal side of the back of mandible are scattered and numerous, instead of grouped with one seta anteriorly and two setae posteriorly as in the two latter forms mentioned above; and pygidium is apically acute, without cerci and with many short, spinelike setae along the lateral margins, instead of bicornute and with only two spinelike setae along each margin near cerci. LeConte in his Classification of the Coleoptera of North America," founded a new genus Veatus, based on tenebriodes Beauvois. Later this species was identified with the European TVenebrio picipes Herbst. His genus was unfortunately lost sight of for many years. From the standpoint of larval characters it should be recognized either as a good genus or a marked subgenus. Seidlitz, in Erickson’s Naturgeschichte der Insecten Deutschland,’ gives a concise key to the larvae of Zenebrio which is here translated and slightly changed to properly set off Veatus LeConte as a distinct genus. 1.

LARVA AND PUPA OF MERINUS LAEVIS (OLIVIER). While collecting in a wood lot near Falls Church, Virginia, July 23, 1918, the author found several prepupal larvae, pupae, and adults under the bark of a large, decaying limb of a maple tree which had fallen to the ground. The material was determined by Dr. FE. A. Schwarz as Merinus laevis (Olivier). Previous records show that the larvae have also been taken from under the bark of chestnut, red oak, and cherry trees. According to Leng this species is found principally in the eastern part of the United States, but specimens in the national collection and in the collection of the Bureau of Entomology, Di- vision of Forest Insects, show that it occurs as far west as Indiana and Missouri. In the North, Aerinus is replaced by the closely allied genus Upis. GENERAL MORPHOLOGICAL DESCRIPTION OF THE LARVAE.” Length 40 mm., color testaceous with head somewhat darker, sub- mentum, presternum, prehypopleurum and anterior-lateral margin of the prothoracic tergum, castaneous-testaceous; anterior and pos- terior margins of prothorax and posterior margins of the following segments finely striated longitudinally.

Research, vol. 22, 1921, no. 6, ser. K., 103, pp. 323-334) to facilitate a comparison between the morphological structures of these two species, which represent the two distinct, but in many respects closely related subfamilies, Tenebrioninae and the Blaptinae.

Pirssry, Of the Academy of Natural Sciences, Philadelphia. It is well known to workers on sessile barnacles that while the subgenera of the genus Balanus rest upon differences in the struc- ture of the walls and basis, the specific distinctions are mainly based upon the opercular plates. No species can be considered well estab- lished until these plates are known. Nevertheless, in dealing with forms of a restricted area it is not difficult to assort the specimens into species by characters of the walls alone, and to determine them if all described species of the region in question are accessible for comparison, either as specimens or represented by sufficient accounts of the wall characters. Thus, most or all of our American Tertiary Balani can be dis- tinguished from one another by characters of the walls. But part of them can not be compared with species of the European Tertiary which were defined by the opercular plates without regard to the internal structure of the wall plates. BALANUS, near EBURNEUS Gould. A small barnacle, about 11 mm. in greatest diameter. The plates of the wall are smoothish with broad radii, as in B. eburneus. The rostrum has 11 tubes. Except close to the base these are closely septate. The septa are closer than in any B. ebuwrneus examined, but in the absence of opercular plates the significance of this difference in a single specimen is doubtful. #2. eburneus has been found in Pleistocene deposits of the Panama Canal Zone.

Conic or subcylindric barnacles of moderate size, similar to B. concavus pacificus so far as the walls are concerned. The parietes are smooth, radii wide with oblique summits. The parietal tubes No. 2515—PROCEEDINGS U. S. NATIONAL Museum, VOL. 65, ART. 2. 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. have no transverse septa; they are often wholly filled up in the fossils. In the largest specimens there are about 26 tubes in the rostrum. The basis is densely porcse, the pores septate towards the peripheral parts. Many specimens retain part of the color, being pink or clouded with pink. Opercular valves unknown. Carinorostral diameter 24 mm.; height 18 mm. This barnacle does not differ in the walls from B. concavus pacifi- cus, recent and Pleistocene in southern and Lower California; but as the several subspecies of B. concavus differ in the sculpture of the opercular valves, it is quite possible that these, when found, will show differences from the west coast form. At present the special name eseptatus is given to the Haitian form. Until the opercular valves can be examined, this seems less likely to lead to error than a provisional identification with the Californian B. c. pacificus. It differs from the Miocene subspecies of concavus from the Atlantic coastal plain and the Panama Canal Zone by various features of the walls, especially the entire absence of transverse septa in the parietal pores.

The parietal tubes are narrow and very numerous, 33 in the rostrum of the type, not transversely septate. The basis is calcareous, and where examined near the edge is not porose. In the type specimen the rostrum is notably longer than the other plates, as in Jf embranobalanus, bat this is doubtless merely an ac- cident of station. Carinorostral diameter 13 mm.; length of rostrum 17 mm. The numerous narrow and nonseptate tubes of the parietes differ- entiate this form from known American species; but as the opercular plates have not been obtained, its affinities are uncertain. Like all of the species treated in this paper, it belongs to the typical sub- genus of Balanus. Station 9750 (B 358 F). Miocene beds, same locality as 9464. One specimen collected by J. S.

Woodring, of the Haitian Geological Survey, some fragmentary crinoidal remains discovered during a cooperative reconnaissance of the Republic of Haiti, which upon examination proved to belong to the pentacrinid genus Balanocrinus Agassiz in Desor. The fossils were derived from strata of early Miocene age in the interior of the island. The occurrence is of interest as being the second one of this genus recorded from North America, the first having been described by me in 1922 from Tamaulipas, Mexico, as Balanocrinus mexicanus, based upon material discovered by Dr. L. W. Stephenson, of the Geologi- cal survey.1. That species, however, is from Upper Cretaceous rocks, so that by the present occurrence the geological range of this Euro- pean genus in the Western Hemisphere is greatly extended. The known range of Balanocrinus in Europe is from Triassic to Miocene, most of the species having been described under the name Pen- tacrinus. The latest occurrence there is in the upper Helvetian of the middle Miocene in Piedmont, Italy, evidenced by stems described by Noelli in 1900 as Pentacrinus lorioli? and referred by Bather to Balanocrinus in the Zoological Record for 1900 (p. 143). The beds in which the crinoid remains under consideration were found belong to the Artibonite formation of the lower Miocene, equivalent to the lower part of the Yaque group of the Dominican Republic. This has been correlated by Cooke and Vaughan with the Burdigalian of the European time divisions.* A full account by Messrs. Woodring, Brown, and Burbank of the Tertiary strati- graphy of Haiti, containing a notation of the present discovery, will appear in a forthcoming report.‘ 1 Proc. U. S. Nat.

The history and characters of the genus Balanocrinus have been exhaustively discussed by Dr. F. A. Bather, of the British Museum, in connection with a rediscription of the two leading species from the middle and upper Eocene of the London clay and the Num- mulitic beds of Biarritz, France;* and reference should be had to this important paper for the fullest information upon the subject. The Haitian material consists of 24 stem-fragments, ranging from a maximum length of 41 mm. down to short pieces of only two or three columnals. The longer pieces from 25 to 41. mm. in length have 9, 10, 11, 12, 14, and 16 columnals, the number 14 being the most frequent. It seems probable that some of these represent com- plete internodes, or intersyzygia, although in none of them are two terminal syzygial faces perfectly shown. The preservation of the specimens is mostly rather poor, the surfaces being more or less covered with carbonate of iron and the edges at the joints often considerably frayed; but enough remain intact in several instances to disclose the joint faces characteristic of the genus. Comparison is naturally suggested with the Italian species of nearly equivalent horizon, but in order to establish the record it will be best first to describe the Haitian form as a new species, BALANOCRINUS HAITIENSIS, new species. Plate 1, figs. 1-10a. Known only from stem-fragments. One of the two longest is 41 mm. in length, tapering from 7 to 6 mm. in diameter, composed of 16 columnals averaging about 2.5 mm. in height (fig. 1); this prob- ably embraces a complete internode, of which the terminal ossicles at either end were cirrus bearing, the evidence of which is obscure, but is reinforced by comparison with the syzygial face in some other specimens. Another of nearly the same length (fig. 8) contains 12 columnals 8.5 to 9 mm. in diameter; averaging 3 mm. high, plus a lower one at each end; one of these is clearly the epizygal, having two cirrus-facets at adjacent radii pointing obliquely upward (drawn with this end uppermost for better lighting), and faint indication of a third one opposite to these two; the corresponding columnal at the other end shows indistinct traces of three cirrus facets alter- nately placed. Two other pieces (not figured), 389 and 35 mm. in height, have 16 and 14 columnals, respectively, of which the terminal faces may be syzygial, thus giving 14 and 12 ossicles to the internode; these terminal ossicles seem rather shorter than the others, but cirrus-facets are not seen. A fifth piece of 33 mm. in length has 14 5 British Fossil Crinoids, XI, Balanocrinus of the London Clay. Ann, and Mag. Nat. Hist., ser. 8, vol. 20, Dec. 1917, pp. 385-407. ART. 3, TERTIARY CRINOID FROM WEST INDIES—SPRINGER. 3 columnals, of which the upper one, with the radial structures much injured by corrosion, may be a nodal, but no facets are visible (figs. 4, 4a). In this specimen it is seen how the radial ridges have been partly decomposed, leaving the petal floors between them promi- nently preserved. This condition is further shown in Figure 6a, where the ridges are destroyed and the resulting pentamerism is emphasized. In Figures 4, 5, and 6 the effect of weathering and decomposition upon the sides of the stem is shown, producing more or less longitudinal projections, in some rounded and in some angular. Figures 2 and 3 show the distortion of the columnals by crushing. All the stem-fragments in their normal condition, that is, when unaffected by weathering, crushing, or chemical action, are strictly cylindrical in outline. The slightly quinquelobate aspect on some of the joint faces is due to peripheral abrasion along the weaker radial lines at the edge of the sectors. The stems range from 6 to 9 mm. in diameter, with about 8 mm. preponderating. The side faces are invariably smooth except where injured, as shown in several figures. Returning, now, to the cirrus-facets, we are fortunate in having one specimen in which they are very plainly shown upon the syzy- gial face of one of the nodal segments, which I suppose to be the epizygal (figs. 9, 9a). They are three in number, two at adjacent radii and the third directly opposite these two, leaving the space at the intervening radii blank. They stand obliquely to the syzygial face, projecting somewhat from its general level, and their position is marked by obtuse ridges diminishing inward and engaging with corresponding depressions in the apposed face of the contiguous nodal segment. In another specimen, not figured, similar facets of the same number and position are faintly indicated. The two facets shown in Figure 8, with a third one opposite to them obscurely seen but not visible in the figure, are similarly disposed. Therefore upon the concurrent evidence of three specimens it may be fairly assumed that the normal number of cirri in this species is three to a nodal, distributed according to the definite plan described by Doctor Bather in his paper of 1917 (p. 396) as “not (all) adjacent, but one is opposed to the two others, being separated from them on each side by a blank radius . . . symbolized thus: AM be br eDr es He shows how the cirrus-facets alternate upon successive nodals, and the same thing probably happens here, there being, as already stated, some evidence of such an alternation in the facets on the terminal nodals in Figure 8. The cirrus-facets are extremely small compared with the size of the stem, not over half the height of the nodal pair, thus resembling those of the Eocene species, B. sub- + PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. basaltiformis as figured by E. Forbes.* They are in marked con- trast to those of the enormous cirri of B. mexicanus,' in which the cirrus-facets fill almost the entire height of the combined nodals. In none of the specimens is any portion of the cirrus itself pre- served. The normal joint-face in nearly all the specimens is so much decomposed that the details of structure are usually obliterated, but as before there is fortunately one specimen in which these are well preserved, showing distinctly the unmistakable characters of Bala- nocrinus (figs. 10, 10a). The petaloid sectors are thoroughly well marked; the floors, or ligament fossae, are large, obtusely triangular, considerably depressed, or excavate. In each sector there are about 10 peripheral crenellae at right angles to the periphery, with usually another one at either side next to the radius not reaching the pe- riphery, which according to Bather’s terminology would be called adradials, thus making 12 crenellae in all; they are short, those which are strictly peripheral being about one-forth the length of the radius, here again contrasting with those of B. mextcanus, in which the length of the crenellae is from one-third to two-thirds that of the radius. On the syzygial face the crenellae are shorter, but ap- parently somewhat less in number (fig. 9a). In other specimens the narrow radial ridges are conspicuous, straight, apparently sep- arated by the radial canal, but perhaps partly confluent (figs. 4a, 5a). The axial canal is apparently round, and the lumen very small. The species with which comparison is invited is the one from the later middle Miocene horizon of Italy, already mentioned, Balano- crinus lorioli of Noelli. It is described from three stem fragments, of which two are figured, respectively 17 and 8 mm. in length, about 6 mm. in diameter, with 9 and 4 columnals about 2.5 mm. in height. The columns are said to be subpentagonal, and have exteriorly some longitudinal furrows, with one or more rows of small pores alternat- ing with them, some of which may be exposed by weathering. Two normal joint faces are figured, both obscure in details of structure. According to the text each petal has 7 to 10 crenulae (denti) at the periphery. The differences shown by comparison of stem fragments alone are therefore of rather minor importance, not greater than might be found in different parts of the same stem. However, we have to make the best of such evidence as we have, considering the rarity and imperfection of the specimens. That which does give to our species a very special interest is the fact that its occurrence in the Miocene of the West Indies furnishes ® Monog. Tertiary Echinod, Palacontogr.

TERTIARY CRINOID FROM WEST INDIES—SPRINGER. 5 a notable addition to the extremely small number of Tertiary crinoids that are known. When we consider the vast extent of Eocene and Miocene sedimentaries of marine origin in Europe, Asia, Africa, Australia, the United States, West Indies, Central and South Amer- ica, many of them thousands of feet in thickness and richly fossil- iferous, abounding in crustaceans, corals, mollusks, and other or- ganisms everywhere associated with crinoids, in ages preceding the Tertiary as well as in the present seas, it is remarkable how few are the remains of crinoids which they have yielded. About 40 species, embraced in 8 or 9 genera, will cover all that have been described, most of them from very imperfect material, such as isolated colum- nals of pentacrinites and centrodorsals of comatulids, among which are doubtless a number of synonyms. Well-preserved specimens, such as are so frequent in the Jurassic and Cretaceous, are almost unknown in the Tertiary, about all we know of the crinoid life of that age being derived from the fragmentary remains above men- tioned, and even these are of rare occurrence. Of the restricted number of species hitherto known, only a single one has been derived from American rocks, namely, the cup of a small comatulid belonging to the Thalassometrinae from the Eocene of North Carolina, described by Emmons? as Microcrinus conoideus. A few other fragmentary remains, not hitherto noted or described, occur in the same beds, and specimens of a species of a comatulid, Nemaster, have been found in the Eocene of South Carolina—all fragmentary and extremely rare amid a profusion of other fossils. Therefore the present species coming from the West Indies is the first stalked crinoid of Tertiary age to be described from the Western Hemisphere. To it will be added another occurrence prob- ably of the same genus, from the island of Tierra del Fuego, which Doctor Bather informs me he will shortly describe. Recent investigations in the West Indies and Panama ?® have shown an extraordinary development of marine Tertiary formations, espe- cially in the Haitian and Dominican Republics, which in places aggregate as much as 1,200 to 2,400 meters in thickness, in many places filled with fossils. Yet out of the extensive collections made during these researches and those previously made by other geologists the 24 fragments upon which this species is based, from a single lim- ited locality, represent all the fossil crinoid remains that have been reported from the West Indies and adjacent lands, a region in the waters of which they are now quite plentiful, amounting as thus 8 North Carolina Geological Survey, 1858, p. 311, figs. 246, 247. ° Vaughan, T.

VOL. 65. far described to 51 species, distributed among 31 genera, of which 12 species, belonging to 8 genera, are of the stalked type.*° The crinoids existed in the Mesozoic in great profusion, their fossil remains having been found to the number of upward of 400 de- scribed species, belonging to more than 40 genera, many of them per- fectly preserved and some of cosmopolitan distribution; while in contrast to the scant 40 species known from the Tertiary there are now described from existing seas 576 species of crinoids, belonging to 142 genera, of which 76 species, of 22 genera, are of the stalked variety. ‘The question naturally arises, what became of the crinoids in the meantime ? The scarcity of crinoids in the Tertiary, and the fragmentary con- dition of their remains, is indeed surprising when compared with their relative abundance in the Jurassic and Cretaceous and also in the recent seas. And yet if the present reefs and beaches were known only in a fossil condition we should find exactly the same state of affairs. The marine Tertiary sedimentaries are composed chiefiy of littoral and reef materials, laid down in shallow seas. The fossils which abound in them belong mostly to organisms of which the hard parts are firmly constructed and capable of enduring the effect of shore action. The crinoids of Cenozoic time, on the other hand, are delicately organized and of fragile construction, so that with a few exceptions like Holopus they are broken up with the least disturb- ance. When a comatulid dies—and comatulids are extremely sensitive— it at once disintegrates, and the only recognizable portion that re- mains is the radial pentagon with the controdorsal, or either of the two alone. The reefs of to-day support a crinoid fauna of approximately 245 species, all of the comatulid type. Most of these are very local, occurring only in a few limited regions, and many are very rare. In the Caribbean region, where in the deeper waters crinoids are often abundant, the shore line records are: Nemaster grandis A. H. Clark: “ Mexico,” 1758.

Such remains have ac- tually been found at Newcastle, New South Wales, Singapore, Ta- ranto, and on the coast of Kent in England. Not far below the surface in a few widely separated localities live large pentacrinites, Zolopus, and Democrinus. The crowns of the pentacrinites are almost as fragile as the coma- tulids, and very soon go to pieces, while the arms of Democrinus are extremely fragile, and the column is rather brittle. Since Dr. W. B. Carpenter reported that once after a hurricane the beach at Barbados was strewn with pentacrinites of all sizes, and 7 of the 11 known specimens of Holopus rangii were found on the beach (6 of them at Barbados), and the first known species of Democrinus was described from a recent breccia at Guadeloupe con- taining a human skeleton, it follows that a recent reef if fossil might contain fragments of pentacrinite stems, fragments of Democrinus stems, or well-preserved specimens of /Tolopus. As the foregoing sketch gives a fairly complete survey of what we might expect if the present reefs and beaches were known only as fossil strata, we may hazard the assumption that the scarcity of crinoids in the Tertiary means nothing more nor less than that at that time the crinoids first began to exist chiefly under the conditions delimiting their occurrence at the present time.

This specimen differs from typical diaspidis by having the mesoscutum strongly metallic blue in color instead of bronzy black and the hairs of mesoscutum appear paler in color and somewhat more numerous.

The United States National Museum has recently received through an exchange with Garcia Mercet a female specimen from Fuenter- rabia, Spain, determined by Mercet as Cheiloneurinus microphagus No. 2517.—PRocEEDINGS U. S. NATIONAL Museum, VOL. 65, ART. 4. i 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. (Mayr). Mercet’s identification of the species is based upon a sup- posed Mayr cotype and should be correct, although, as Mercet has. pointed out, the cotype differs from Mayr’s description in the color of the wings. As determined by Mercet the species is undoubtedly identical with Cheiloneurus diaspidinarum Howard, Aphidencyrtus aspidioti Gi- rault, and A phidencyrtus aspidioti, var. brittanicus Girault. Howard’s description of Cheiloneurus diaspidinarum was drawn from two females (only one of which can now be located) reared. at Liberty, South Carolina, from Lepidosaphes ulmi Linnaeus. Aphidencyrtus aspidioti Girault was described from three females said to have been reared from Aspidiotus perniciosus Comstock at Lansing, Michigan. Only the type slide bearing a single female has been located. The variety brittanicus was described from three females, two of which are in the National Collection on a single slide, and which were reared at Manchester, England, by A. D. lnms from Lepidosaphes ulmi. Tn connection with the description of Aphidencyrtus aspidioti, var. brittanicus, Girault mentioned specimens which he stated were ap- parently the males. Two slides bearing the name in Girault’s hand- writing and data similar to that of the type are in the national col- lection and undoubtedly constitute the material referred to by Girault. Both specimens are males of Anabrolepis zetterstedte (Westwood) and will be further discussed under that species. Besides the specimens already mentioned, the national collection contains eight card mounted females from the same source as the type material of Girault’s variety brittanicus but not part of the type ma- terial and three females labeled “ Par. of A/ytilaspis sp. and Aspidio- tus spurcatus, Pontvalains, Sarthe, France (P.

Imms at Manchester, Eng- land, from Lepidosaphes ulmi (Linneaus). I can see no reason to doubt the correctness of the determination. These specimens were apparently reared from the same material as were the types of Aphidencyrtus aspidioti, var. brittanicus Girault, which species (as represented by the female type) has been shown to be a synonym of Cheiloneurinus microphagus (Mayr) (ante p. 2). Two males from the same source which are in the National Museum and which were described by Girault as apparently the males of his var. brittanicus are, however, undoubtedly males of Anabrolepis zetterstedtii instead. Four females in the National Collection labelled “Par. of Mytilaspis sp. & Aspidiotus spurcatus, Pontvalains, Sarthe, France, P. Marchal” and which have been previously determined, apparently by Ashmead, as Habrolepis dalmani (Westwood) are not that species but belong, in my opinion, to the present species. The species has been recorded from North America by Ashmead (1900) and again by Girault. Ashmead did not indicate the source of his specimens, which have not been located. Girault (1917) re- corded two males reared from Lepidosaphes ulmi at Monmouth, Maine, under the name of Aphidencyrtus aspidioti. Again (1920) he recorded a female from the same host and locality under the name Habrolepis zetterstedtii. Girault’s specimens, like those of Ashmead, are missing, but there can be little doubt that the males referred to in the first reference are really the same species as the female sub- sequently recorded, and the identification of the female was probably correct. In addition to the above records the writer has seen two females labeled as having been reared at Columbus, Ohio, by Robert A. Young from Diaspis ostreaeformis. These bear the name label Ha- brolepis dalmani, but appear to be zetterstedtiz. A single male specimen was recently received from J. McDunnough, of the Cana- dian Department of Agriculture, and which was reared at Vernon, British Columbia, from Lepidosaphes ulmi. Timberlake (1920) has transferred the species to his new genus Anabrolepis, where it apparently belongs. Family EUPELMIDAE. Genus LECANIOBIUS Ashmead. Lecanviobius ASHMEAD, Proc. Ent. Soe.

Both species are, so far as known, neotropical in distribution. Crawford? has already pointed out that his species, Zalophothrix mirum, is a synonym of Lecaniobius cockerelli Ashmead. LECANIOBIUS CAPITATUS, new species. This species is at once distinguished from cockerelli by the fact that the head, as viewed from in front, is not nearly twice as broad as high, although distinctly broader than high; the area between the inner eye-margin and the margin of scrobe is nearly as broad at the lower extremity of the eyes as at the upper angle of the scrobe in- stead of much narrowed below; in dorsal aspect the head is more strongly transverse, the frons much less flattened and more nearly perpendicular; the antennal scape is longer, about six times as long as thick; the general color is much darker.

This species resembles closely the description and figure of Z. saissetiae Silvestri? and apparently has the same habit of attacking scale insects, but it may be distinguished by the fact that the oviposi- tor is much less strongly exserted, and is not dark at tip, the wings appear to be less strongly infumated, the legs are somewhat differ- ently colored and the first tergite seems to be much more deeply incised at apex.

Head strongly sculptured, the face and cheeks with conspicuous silvery white pubescence; viewed from above, thick antero-posteriorly, twice as broad as long and as broad as the thorax at tegulae; occiput immargined; frons above the scrobes flattened, narrowest at the apex of scrobes where it is nar- rower than behind the posterior ocelli; ocelli in an equilateral tri- angle, the ocellocular line equal to the diameter of an vcellus; viewed from in front, the head is slightly broader than high, subtriangular with the vertex nearly straight and the sides and cheeks rounded; antennal groves deep and sharply defined, confluent above, separated below by a triangular plate which is sharply defined laterally and extends upward more than half the length of scrobes; front ocellus less than its own diameter above apex of scrobes, the latter more finely sculptured within than the remainder of head; eyes nearly cir- cular and covered with very short inconspicuous pile; malar space approximately as long as the rather short scape; scape distinctly shagreened and about four times as long as broad; pedicel approxi- mately two and one-half times as long as its apical breadth, very slightly longer than the third and fourth joints combined; third joint small, about twice as broad as long and about half as long as the fourth; fifth and sixth joints each longer than the fourth and longer than broad; seventh subquadrate; eighth to tenth inclusive slightly broader than long; club 3-jointed, subovate and about as long as the three preceding joints combined. Thorax pubescent, less strongly sculptured than the head, the mesepimeron finely lineolate- reticulate and destitute of pubescence; axillae narrowly separated at base; propodeum laterally and the hind coxae outwardly, except a triangular area down the middle, densely clothed with conspicuous white pubescence; marginal and submarginal veins subequal, post- marginal longer than stigmal, the submarginal with about eleven or twelve stiff bristles dorsally; wings more than ordinarily densely * Boll.

Family APHELINIDAE. APHELINUS SANBORNIAE, new species. Very similar to mali Haldeman but may be distinguished at. once by the entirely black abdomen. The forewing basad of the hairless streak bears fewer hairs in the angle behind the marginal vein than does the wing of mali, the front tibiae are largely black or at least blackish basally and the ovipositor does not protrude beyond apex of abdomen. Female.—Length, 0.8 mm. Head and thorax smooth and polished; eyes hairy; antennae rather short, six-jointed; the scape spindle- shaped and approximately as long as the pedicel and three funicle joints combined; pedicel about twice as long as broad at apex and not quite as long as the entire funicle; first two funicle joints sub- equal and each approximately twice as broad as long; third funicle joint distinctly shorter than the pedicel but hardly one and one-half times as long as broad; club approximately equal to the scape in 8 PROCEEDINGS OF THE NATIONAL MUSEUM, VOL. 65. length; forewing distad of hairless streak thickly ciliated, basad of hairless streak with a single obliquely transverse row of hairs bor- dering the streak and from three to six similar hairs in the angle formed by the marginal vein and the transverse row of hairs; ab- domen triangular, smooth and polished; ovipositor barely visible at apex. Head, thorax, and abdomen shining black; antennal flagellum pale orange yellow, the scape black; legs black with the extreme base and apex of anterior and middle tibiae very narrowly, the hind femora entirely and all tarsi, except at apex, pale yellow; wings hyaline. Male.—Agrees with the female except that the third funicle joint is distinctly longer and thicker than the pedicel, about equal in length to the pedicel and first two funicle joints combined; the scape on the ventral side has three small round tubercle-like sensoria or glands which are visible only in slide mounts under high magnification ; and the abdomen is shorter and less distinctly triangular.

APHELINUS JUCUNDUS, new species. Resembles semflavus Howard but may be distinguished by the yellow face and somewhat shorter third funicle joint. Also re- sembles howardi Dalla Torre but differs from the description of that species in the more extensive and differently arranged ciliation of the forewing. Female.—tLength, 1.2 mm. Frons, mesoscutum and scutellum dis- tinctly finely shagreened; the frons nearly opaque; mesoscutum pubescent and more or less shining; propodeum very finely trans- versely rugulose; abdomen nearly smooth; mesopleura weakly sculp- tured and shining; hind coxae polished.

Male.—Unknown. Type-locality— Whittier, California. Type.—Cat. No. 26177, U.S.N.M. Host—Macrosiphum solanifoliti Ashmead. Described from nineteen card-mounted and five slide-mounted specimens, apparently all females, reared from the potato aphid by H. Compere, February 20, 1922, and received by the Bureau of Entomology from H. M. Armitage. Also two females taken at the same place by E. A. Hartley, who first called the writer’s atten- tion to this form. APHELINUS AUREUS, new species. Agrees very closely with avtomatus Girault but differs in its beau- tiful bright orange color and in having the scutellum and posterior half of the mesoscutum reticulated instead of shagreened. Female——Length, 1 mm. Pedicel barely as long as thick; first and second funicle joints small and transverse; third funicle joint subquadrate; club approximately four times as long as the penul- timate joint and somewhat thicker than usual. Mesonotum ante- riorly granular, the posterior half and the scutellum reticulate, the areas hexagonal or pentagonal and rather large; forewings moder- ately broad, the marginal and submarginal veins subequal, disk of wing distad of the hairless streak with moderately dense ciliation; basad of the hairless streak with very sparse coarse cilia; abdomen oval with the exserted portion of the ovipositor sheaths about equal in length to the hind metatarsus. Eyes and ocelli dark; head, thorax and abdomen bright orange or golden yellow but with a narrow median line on the mesoscutum and scutellum and the sutures for the most part paler; wings hyaline; the venation and the legs con- colorous with the body or only slightly paler. Male—Similar in every way to the female except that the abdomen is somewhat shorter. Ty pe-locality—Santa Paula, California. Type—Cat. No. 26178, U.S.N.M. Host.—Chaitophorus salicicola Essig. Described from a single female and two males mounted on slides and reared by E. O. Essig from the above named host. The writer at first determined these specimens as automatus Girault but after a study of all the species in the National Collection is now convinced that they should be held distinct. 10 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. APHELINUS PERPALLIDUS, new species. This species differs from all of the other yellowish North Amer- ican species except aureus Gahan and automatus Girault by having the ciliation of the forewing basad of the hairless line very sparse and coarse. It differs from both aureus and automatus by having the first and second funicle joints not transverse but each about as jong as broad, the third funicle joint a little longer than broad, and the ovipositor not at all exserted. , Female.—Length, 0.9 mm. Antennal club not much thicker than the third funicle joint and about four times as long as that joint; eyes bare or practically so; frons, mesonotum and scutellum dis- tinetly finely shagreened; marginal vein of the forewing slightly shorter than the submarginal or subequal to it; discal ciliation of forewing distad of the hairless line moderately dense and short; basad of the hairless line sparse and irregular, scattered over most of the area behind the marginal vein and much coarser and longer than the cilia beyond the hairless line. Body above very pale green- ish yellow; beneath and including all legs nearly white; wings hya- line; venation pale yellowish; antennae pale.

Eriophilus mali HALDEMAN, Penna. Farm. Journ., Aug., 1851, p. 131. Aphelinus mali Howarp, Rept. U. S. Com. Agr. (1880), 1881, p. 356. Aphelinus varicornis GirAtLr, Psyche, vol. 16, 1909, p. 29. Three cotype specimens of varicornis Girault mounted on slides are in the National Collection and apparently differ in no way from specimens of mali Haldeman. The wings show no more infuscation than do those of mali, and the ciliation of the forewing proximad of the hairless streak is practically the same despite Girault’s statement to the contrary. APHELINUS SEMIFLAVUS Howard. Aphelinus semiflavus Howarp, Ent. News, vol. 19, 1908, p. 367. Aphelinus brevipennis GrrAuL?T, Descriptiones Stellarum Novarum, 1917, p. 18. Types of both the above named species are in the National Col- lection and have been compared. Except for the abbreviated wings, the types of brevipennis differ in no way from typical semiflavus. ART. 4, NEW PARASITIC HYMENOPTERA—GAHAN. rt That this difference is not of specific value is apparent from an examination of the 20 specimens constituting the original type series of semiflavus. In this series the size of wings vary from normal to scarcely half normal size. The same tendency to vary is shown by a series of specimens reared from Myzus persicae Sulzer at Colum- bus, Ohio, by E. A. Hartley and the same tendency is shown by the three specimens constituting the type series of brevipennis. Both sexes show the same tendency to vary in the size of the wings but the reduction is apparently carried to a greater extreme in the male. In addition to a large number of specimens reared from Myzus persicae the National Collection possesses a male and female of this species reared from A/yzus, species on Adquilegia, at Lafayette, Indiana, May 7, 1916, by J. J. Davis. APHELINUS LONGICLAVAE Mercet. Aphelinus longiclavae Mercer, Assoc. Espan. Prog. Ciencias (sep.), 1911, p. 14. Aphelinus capitis Rust, Ent. News, vol. 26, 1915, p. 73. This species was originally described as a parasite of Aspidiotus hederae Vallot in Spain. Aphelinus capitis was described from California where it was said to parasitize a number of different species of scale insects including Aspidiotus hederae. While no European specimens of longiclavae have been seen by the writer two cotypes of capitis together with three other California specimens reared by E. O. Essig from Aspidiotus hederae have been compared with Mercet’s description and seem to agree so perfectly that I have no hesitation in declaring Rust’s species to be a synonym.

Five slide-mounted specimens reared from Aspidiotus destructor Signoret on coconut palm at Rio Pedras, Porto Rico, October 17, 1921, by G. N. Wolcott, have been determined by the writer as this species. The record is interesting as constituting the first identifica- tion of this European species from the Western Hemisphere. APHELINUS ASHMEADI, new name. Aphelinus howardii ASHMEAD, Trans. Ent. Soc. London, 1900, p. 264 (not howardit Datta Torre, Cat. Hymen., vol. 5, 1898, p. 221). This species was described from a single male specimen from the island of Grenada, West Indies. The type is in the British Museum. If really an Aphelinus the species should be easily recognized by the unusually long male antennae. 12 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. APHELINUS MARLATTI (Ashmead).

Both of the above-cited descriptions are based upon ‘the same three identical specimens. The Ashmead description was apparently un- known to Girault. In addition to the three specimens mentioned as types by both authors the National Collection now contains two other specimens acquired by gift from the Kansas State Agricultural Col- lege in 1920, and which were reared by Mr. Marlatt at the same time and from the same source as were the types. Two of the type speci- mens have been mounted on a slide and ground to fragments beneath the cover-glass by Girault. The actual type specimen is mounted on a card point in good condition except for loss of both antennae, and the pin bears a label on one side of which is written the Ash- mead name and on the reverse side the Girault name.

With the exception of flavoscutellum Ashmead and cognatus How- ard the above synonymy is that given by Doctor Howard in his Revision of the Aphelininae of North America. The writer recently had occasion to compare the types of Coc- cophagus lecanii (Fitch), C. cognatus Howard, and C. flavoscutellum Ashmead, all of which are in the National Collection. After care- ful comparison and study the conclusion was reached that all three names refer to the same species. Fitch’s species is slightly variable us to the extent of the yellow marking on the scutellum and both Howard’s and Ashmead’s types fall well within the range of this variation and can not be distinguished from lecanzi otherwise. The species attacks a long list of Lecaniine and other scale insects and is widely distributed, having been recorded from Europe by Masi* and others; from Japan by Nakayama;* from Hawaii by Fullaway * and in America it is known to occur from the Atlantic to the Pacific and from Florida to Ontario, Canada, as well as in several of the West Indian Islands. 3 Boll.

Ent., vol. 31, 1916, p. 44. Types of both the above named species are in the National Collec- tion and are identical in every way. The species is rather easily recognized by reason of its conspicuous dark markings, a large blotch at the middle of pronotum, the entire propodeum, a transverse band on the abdomen sometimes embracing the whole apical half of abdo- men being black or blackish and the axillae usually dark brownish. The praescutum is uniformly and closely set with rather coarse hairs, but lacks paired setae except for one pair at the posterior margin just in front of the scutellum; the scutellum has three pairs of setae and is otherwise bare; the female antennae are distinctly clavate, the club distinctly thicker than the funicle and subequal to it in length; the first funicle joint although the smallest joint is somewhat longer than broad, while funicle joints two and three are subequal and each about as long as the pedicel. None of the funicle joints in the fe- male are strongly corrugated. The male is like the female except that the antennae are much longer, the first funicle is the thickest joint, the following joints successively diminishing in thickness and all of the flagellar joints are strongly corrugated. The types of ochraceus were from Alameda County, California, reared from Lecanium, species on Adenostema fasciculatum. The types of bifasciaticorpus were from Cape Town, South Africa, reared from Lecanium hemisphaericum Targioni. In addition to the type material the writer has seen specimens from Berkeley, California, sent in by E. O. Essig and from Queenstown, South Africa, collected by E. M. Rust and sent in by Harold Compere, all of which are said to have been reared from Saissetia oleae Bernard. Coccophagus javensis Girault is very similar to this species but differs in that the joints of the funicle in the female are all subequal in length and thickness and not narrower than the club which tapers gradually from base to apex and all of the flagellar joints are strongly corrugated. The propodeum is not as dark as in ochraceus although more or less fuscous and the axillae are not darker than the scutellum. ANERISTUS CEROPLASTAE Howard. Aneristus ceroplastae Howarp, Can.

The former was de- scribed from specimens parasitic on Ceroplastes euphorbiae Cock- erell in Jamaica and the latter from specimens reared from Cero- plastes actiniformis Green as well as several other species of scale insects in Ceylon. The species is apparently widely distributed, the national collec- tion containing material from Hawaii; Los Banos, Philippine Islands; St. Croix, Virgin Islands; and Ancon, Canal Zone, in addi- tion to the type localities.

Sci. vol. 18, 1921, p. 99, pl. 1, fig. 2. The National Collection contains several slide mounted cotypes of diaspidicola Silvestri received from the author through Dr. L. O. Howard. A single slide-mounted cotype of négatae Nakayama is also in the collection. These cotypes have been compared and seem to be identical. The former name was proposed for specimens of a parasite reared from Aulacaspis pentagona (Targioni) from South Africa and the latter for a parasite of the same scale in Japan. The National Collection also contains three slides bearing a large number of specimens said to have been parasites on mulberry scale, Gifu, Japan, reared by U. Nawa, January 30, 1899. The mulberry scale mentioned was doubtless Aulacaspis pentagona. One slide in the collection bears two specimens reared from Aulacaspis penta- gona at Campinas, Brazil, by F. Noack. This species is quite similar to berlesei Howard, but apparently differs by having smaller wings with the marginal fringe a little more than half as long as the greatest wing breadth; the praescutum bears only two pairs of chaetae, the anterior pair being situated approximately midway between the anterior and posterior margins and about as far from each other as from the lateral margins, the posterior pair located just in front of the scutellum; the first dorsal segment of the abdomen is distinctly reticulated at base. ENCARSIA FORMOSA, new species. This species belongs to the Zuteola group in which the middle tarsi are 4-jointed, the fourth and fifth joints being connate. It differs from luteola Howard by having the dorsum of the thorax distinctly, almost opaquely, sculptured, and it is also to some extent darker in color. May be distinquished from guaintancet Howard by the wholly black scutellum. Female.—Length 0.6 mm. Antennae rather long and cylindrical; pedicel longer than the first funicle joint, the latter approximately ART. 4, NEW PARASITIC HYMENOPTERA—GAHAN. 15 one and one-half times as long as thick; second, third, and fourth joints subequal and each slightly more than twice as long as thick; club 2-jointed, the joints subequal and each about as long as the fourth funicle joint; occiput distinctly sculptured and the vertex more finely so; mesoscutum, scutellum, and axillae, when viewed through a binocular microscope, with distinct, fine, nearly granular sculpture (mounted in balsam and under a compound microscope this sculpture is seen to be a fine reticulation, the enclosed areas on the middle of the scutellum compressed from the sides and forming elongate longitudinally arranged cells, while elsewhere on the scu- tellum, as well as on the mesoscutum and axillae, the enclosed areas are irregular and not especially compressed) ; forewings with the discal ciliation nearly uniform over the whole surface except caudad of the submarginal vein where they are for the most part bare; marginal cilia longest at the posterior apical border of the wing; marginal vein a little longer than the submarginal, the stigmal strongly curved; middle tibial spur about half as long as the basal joint of tarsus; middle tarsi 4-jointed, the fourth and fifth joints connate but with a slight constriction, indicating the original separa- tion; abdomen a little longer than the thorax; rounded at apex, and apparently sculptureless; ovipositor slightly extruded. Antennae, legs, and abdomen pale yellow or nearly white, the antennae very shghily infuscated; face, cheeks, and posterior orbits black; frons, reore or less of the vertex, and the occiput above very dark orange yellow or brownish; thorax dull black, with the groove separating axillae from mesoscutum faintly brownish; wings hyaline, venation fuscous; hind coxae blackish at base. Male—Length 0.6 mm. Antennal pedicel not much longer than broad, much shorter than the first funicle joint which is more than twice as long as thick, about as long as the second funicle joint and somewhat thicker; second, third, and fourth funicle joints and the basal joint of club subequal in length and breadth, about three and one-half times as long as thick; apical joint somewhat shorter; all funicle and club joints with distinct, widely separated, longitudinal striae; structure and sculpture otherwise like the female. Head mostly brownish yellow, darker on the cheeks and below the an- tennae; thorax blackish with the mesonotal grooves pale yellowish and the abdomen mostly blackish with sutures somewhat yellowish; antennae and legs as in the female.

Three of the latter specimens mounted on card points, the other one in balsam. Since the above description was drawn up additional specimens of this species have been received as follows: a large series from Wooster, Ohio, reared by J. S. Houser from pupae of 7’rialeurodes vaporariorum (Westwood) in a greenhouse, February 5, 1923; a large number of specimens reared March 8, 1923, from pupae of the same Aleurodid taken in a greenhouse on the Department of Agriculture grounds at Washington, D. C., by W. H. White. The host insects from which the type specimens came were not definitely determined but in all probability they were the same species which served as host for the Ohio and District of Columbia specimens. The parasitized Aleurodid pupae turn black in color and are easily distinguished from healthy pupae which are greenish. The parasite was reported as extremely abundant in both the Wooster, Ohio, and Washington, D. C., infestations. Family PTEROMALIDAE. RHOPALICUS PULCHRIPENNIS (Crawford).

Types of Spintherus pulchripennis Crawford and of Rhopalicus americanus Girault are in the U. S. National Museum and have been compared. The two are identical. In the opinion of the writer the species is more properly placed in Rhopalicus Foerster than in Spintherus Thomson. EUPTEROMALUS COGNATUS, new species. Very similar to viridescens (Walsh) but differs from that species by having the joints of the funicle slightly shorter, the occiput a little more concave, the antennal groove somewhat deeper, the occi- pital carina very weakly developed, and the punctation of the head and thorax a little stronger. Female.—Length, 2 mm. Head and thorax with the usual reticu- late-punctate sculpture common to the group but the punctures slightly deeper than in most of the other species; abdomen shining, with the tergites, except the first, very obscurely reticulated; scutel- lum sculptured alike all over or with only a very slight indication of a differently sculptured area at apex; propodeum punctate with a weak median carina. Head viewed from above broader than the thorax; occiput rather deeply concave medially and very weakly margined; posterior ART. 4. NEW PARASITIC HYMENOPTERA—GAHAN. LG orbits less sharply receding from the eye margins than in most of the other species; viewed from in front the head is perceptibly broader than high (about 6:5), truncate at the mouth, the cheeks rounded and the vertex distinctly though not greatly arched above the eyes; viewed from the side the front profile is weakly convex, the face below the antennae receding only slightly; mandibles each with four teeth; maxillary palpi 4-jointed, the apical joint the longest joint, the penultimate joint the shortest and hardly half the length of the last; labial palpi 2-jointed; antennal scape cylindrical and as long as pedicel, ring-joints and three first funicle joints com- bined; ring-joints distinct, subequal; funicle joints all subequal and each a little broader than long; club 3-jointed and equal in length to the last three funicle joints combined; mesoscutum about equal in length to scutellum, with the parapsidal grooves present anteriorly but effaced on the posterior one-fourth; scutellum moderately convex or at least not conspicuously flattened as in dubius Ashmead; propodeum moderately hairy laterally, the apical neck distinct but rather short, the spiracles elliptical and moderately large; marginal and postmarginal veins practically equal, the stigmal vein shorter; abdomen pointed ovate, not longer than the thorax and usually a little narrower than the thorax; first tergite comprising approxi- mately one-third the total length of abdomen; second tergite a little less than half the first; following tergites shorter. Color of head and thorax dark aeneous; abdomen mostly metallic blue-black with the first tergite metallic green; wings hyaline, venation pale yellowish; antennal flagellum dark brown, scape and pedicel reddish testaceous; coxae concolorous with thorax; all femora brownish testaceous, the tibiae usually a little clearer testaceous and the tarsi still paler. Male.—Length, 1.7mm. Agrees with female except that abdomen, viewed dorsally, is nearly circular in outline and not over two-thirds as long as thorax, and the funicle joints are all practically as long as broad. Type-locality.—Ballast Island in Lake Erie. Type.—Cat. No. 26181, U.S.N.M. The type series consists of twenty specimens, many of them more or less broken and imperfect, received from Miss Mary Auten and all reared by her from the egg capsules of spiders. The type, allo- type, and several paratypes were reared, according to the collector, from the egg capsules of Avranea frondosa Walckenaer taken on Ballast Island in Lake Erie. Other paratypes are said to have been reared from the capsules of petra sclopetaria Emerton taken on South Bass and Gibraltar Islands in the same lake while two specimens also taken on South Bass Island are said to have come from the capsule of Philodromus canadensis. 18 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. Judging by host records of related species it seems more probable that this species is actually parasitic upon some dipterous or hy- menopterous larva infesting the egg capsules than that it is present as a parasite of the spider’s eggs.

Letrastichus blepyri Ashmead was originally described from two specimens reared at Rosewell, New Mexico, by T. D. A. Cockerell as a secondary parasite of Phenacoccus cavalliae Cockerell. Its actual host is said to have been Blepyrus phenacocct Ashmead infesting the scale insect. 1’. detrimentosus Gahan, the types of which are also in the national collection, was described from twenty specimens said to have been reared from Coccinella sanguinea at Lakeland, Florida, by G. G. Ainslie. A review of Ainslie’s notes shows that Homalotylus termi- nalis (Say) was also present in this rearing under circumstances which make it highly probable that the Womalotylus was the actual host of the 7'etrastichus. The writer has more recently received two specimens reared at Murray, Utah, August 24, 1918, by P. H. Timberlake from Micro- terys, species infesting Pulvinaria bigeloviae Cockerell; two speci- mens reared from Physokermes insignicola (Crawford) at Santa Maria, California, in April, 1912, by Timberlake; one specimen from Alhambra, California, reared from Saissetia oleae (Bernard), by Harold Compere; two specimens reared at Arcadia, California, by 20 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. H. Compere, from Sazssetia oleae upon which they were believed to be secondary; one specimen from Santa Maria, California, reared by H. Compere, from Physokermes insignicola and probably para- sitic upon Aphycus physokermes Timberlake which was known to be present; and one specimen reared from S. oleae by H. S. Smith, in California, the exact locality not given. Study of this new and better material in conjunction with the types has convinced the writer that blepyri Ashmead and deteri- mentosus Gahan are the same species. The species is without much doubt normally a secondary parasite of various scale insects and Coccinellidae and appears to be quite widely distributed in North America and may also be found else- where. Superfamily SERPHOIDEA. Family SCELIONIDAE. Subfamily BAEINAE Genus BAEUS Haliday. All descriptions apparently credit the wingless females of this genus with having the scutellum absent. As viewed by the writer this is not strictly true of the species standing under this name in the National Collection. The mesoscutum is large, occupying most of the thoracic dorsum, but between this sclerite and the abdomen are two transversely linear sclerites, variable in size but always discernible. ‘hese two plates apparently represent the scutellum and propodeum respectively. The anterior plate is usually somewhat longer (antero- posteriorly) than the posterior and the latter bears what appear to be the very minute spiracles. BAEUS ROTUNDIVENTRIS, new species. Very similar to B. piceus Ashmead but slightly larger, a little more strongly sculptured on thorax and abdomen, the abdomen more rotund, the antennal club blackish instead of reddish testaceous, and the head somewhat lighter in color. Also similar to niger Ashmead but may be distinguished at once by the broader and more rounded abdomen, which is more sparsely clothed with longer hairs, and by the somewhat longer though strongly transverse propodeal sclerite. Female—tLengths 0.8 mm. Wingless. Head, thorax, and abdomen more or less shining, but with distinct, fine reticulate sculpture and sparsely clothed with rather long hairs; eyes distinctly hairy; an- tennae 7-jointed, the club solid and longer than the funicle; first funicle joint the longest of the funicle joints, pedunculate at base; following joints of funicle slightly broader than long; pedicel large, ART, 4.

By Joun B. Ressipg, Jr., Of the United States Geological Survey. Species of the genus Hutrephoceras are rare in the Tertiary de- posits of the United States. Whitfield: described one, as Nautilus cookana, from the Shark River marl of New Jersey, probably of middle Eocene age, but none, so far as the writer knows, has been described from the Eocene of the southeastern United States. The specimen on which this paper is based is therefore of considerable interest, and, though it is perhaps not so complete as one might wish a type specimen to be, most of its essential characters can be made out and are worth recording for the benefit of future col- lectors. The specimen was found in silicified marlstone at Perkins Bluff on Black River, Georgetown County, South Carolina, by Earle Sloan, of Charleston, South Carolina., then State geologist, and listed as E'nclimatoceras ulrichi White.? It was borrowed from Mr. Sloan by Dr. C. Wythe Cooke, of the United States Geological Survey, in order to verify the identification, and when found to differ from the type of 2. ulrichi was placed in my hands for de- scription. At Doctor Cooke’s suggestion, Mr. Sloan has deposited the specimen in the United States National Museum. Because of the supposed presence of E'nclimatoceras ulrichi, a Mid- way species, the beds at Perkins Bluff, belonging to the Black Mingo formation, were regarded by Sloan as of Midway age.? However, as the rock matrix of the type of Hutrephoceras sloani contains impressions of a coral identified by Dr. T. W. Vaughan as Haimesiastraea conferta Vaughan, a species ranging through the Midway and Wilcox groups of Alabama, the geologic age of the beds might be either Midway or Wilcox. 1 Whitfield, R.

According to Hyatt: + This genus includes these forms like the type #. dekayi, which have globose ananepionic substages, increasing subsequently with great rapidity in all their diameters. The ana- and metanepionic substages are highly tachygenic and these shells have very small, and often hardly perceptible and much flattened, umbilical perforations. The siphuncles are subdorsan from the apex through the nepionic stage in some species, in others this position is not maintained, but the siphuncle is generally in the later stages near the dorsum and in the ephebiec stages it is dorsad of the center. The nepionie stage has longitudinal ridges and transverse bands, the tormer disappearing in adults which are smooth. The form of the whorl in section is nephritic from an early age and changes but little throughout life. The sutures are almost straight, having but slight ventral lobes, broad ventrolateral saddles, lobes on the umbilical zones, and deep lobes in the zone of impression. There are no annular lobes at any stage of development. Hyatt’s remarks about the genotype are all based on specimens from the Western Interior (“ Dakotah ”), whereas the true 2’. dekayi (Morton) is from New Jersey. it would seem, therefore, that the real genotype is the unnamed species mistakenly referred by Meek and most other writers to 2. dekay?, From the four other genera originally assigned to the family by Hyatt Hutrephoceras may be distinguished most easily as follows: From Digonioceras Hyatt in having a nephritic rather than sub- trigonal cross section of the whorl in the adult; from Cenoceras Hyatt in having a nephritic rather than subquadragonal cross section of the whorl in the adult; from Cymatoceras Hyatt in the lack of broad ribs on the shell and in the straighter suture; from Nautilus Linnaeus in the broad outline of all the later stages, the general posi- tion of the siphuncle dorsad of the middle of the septum, and the straighter sutures. (See fig. 16.) From the genera Hercoglossa Conrad (Enclimatoceras Hyatt) and Aturia Brown of the family Clydonautilidae, which also occur in the Eocene, L'utrephoceras differs sharply in suture. (See fig. 1a.) The writer has examined a number of specimens of L'utrephoceras of Cretaceous age. The sutures are very much alike in all of them; the shell of all of the larger specimens, when preserved, is nearly smooth; and the position of the siphuncle is very much the same in all. The conspicuous differences between them are in the form of the cross section of the whorl and the size of the shell. These seem to offer a valid basis for separation into species, and, so far as the writer’s material goes, form and size are constant within considerable *Hyatt, Alpheus, Phylogeny of an acquired characteristic: Amer. Philos. Soc. Proc., vol. 32, p. 555, 1894.

It is likely that if complete and well-preserved shells were available numerous other differences would be found, but it seems desirable to distinguish the various groups that can be recognized now even though some of them are difficult to separate on the basis of such details as are commonly preserved. EUTREPHOCERAS SLOANI, new species. Shell of medium size, the largest diameter of the type specimen preserved being about 140 mm.

No. 352,559 U.S.N.M. 4 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. Eutrephoceras sloani differs from #. cookana Whitfield ® chiefly in size, the latter species attaining a diameter of 300 mm. The cross section of the whorl is much the same in both species but is a little broader in the Shark River species. It is possible that further col- lecting will show that /. sloani attains a large size, has a considera- ble range of variation in form, and is therefore inseparable from 1’ cookana. However, it seems best with the material now in hand to consider the South Carolina species as distinct from the New Jersey species. The other American species of the genus Hutrephoceras known to the writer are Upper Cretaceous in age and have nearly all been referred at some time to /’. dekayi (Morton), though unques- tionably different. 4. dekayi (Morton), as refigured by Whitfield,° from the Navesink and Redbank formations of New Jersey is about the same size as /. sloani but is stouter, the proportion of height to width of the cross section of the whorl being about 3 to 4. Z. bryant (Gabb), as refigured by Whitfield,? from the Vincentown sand of New Jersey, is more compressed than /. sloaniz, the proportions of height to width of the cross section of the whorl being about 8 to 7. An undescribed species from the Ripley formation of Alabama is stouter and apparently of consistently smaller size than LZ’. sloani. Another from the Navarro formation of Texas is separated by the presence of a persistent flattened zone on the venter. Ss anv. 7. NEW SPECIES OF MOTHS—SCHAUS. 69 LIOPASIA PURPUREALIS, new species.

From Dr. Edward M. Kindle, of the Canada Geological Survey, the writer has received for examination a large tooth of Desmostylus, which was presented to the Victoria Memorial Museum, at Ottawa, by Dr. C. W. Newcombe, of Victoria, British Columbia. It had been purchased from a dealer in curiosities and was reported to have been brought from Alaska. This report may be true, but it is hardly to be depended upon. The tooth no doubt belongs to Desmostylus, but in- asmuch as neither the locality nor the formation is known it would be unsafe to identify it specifically. It appears to be a left upper molar. The tooth sent from Victoria (pl. 1, figs. 1,2) had not yet come into use, the unabraded summits of its columns showing each the peculiar depression and central nipple-like elevation. Only the base of the reot is present, and there are indications that it consisted of two fangs. The greatest length of the tooth is 61 mm.; the height 57 mm., including the base of the root. From the edge of the enamel to the summit of the columns is 51mm. The thickness, where great- est, is 88 mm. The tooth consists of eight columns. Of these, three form a front transverse row; then come two rows, each of two columns; and at the rear is a single column. The transverse rows are oblique to the axis of the tooth, being directed from the outside inward and backward, as may be seen by figure 1 cited. As will be observed, the intervals between the columns are occu- pied by cement, and this is of a lighter color than the surface of the enamel. This cement rises from the root to the summit of the columns. Below the bases of the second and the third columns the cement continues to the center of the base of the root, lying evidently in a valley which seems to mark the division of the root into two fangs. The front of the tooth presents two tracts of cement, one on each side of the median column, and it spreads over the front of these anterior columns nearly half way to their sum- mits. It is probable that originally a large part of the crown was No. 2521I—PrRoOcEEDINGS U. S. NATIONAL Museum, VOL. 65, ART. 8. 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, 65. covered with a thin coat of cement. On the inner face of the tooth there still adheres a part of the maxiliary bone. So far as the writer sees, it is impossible to determine where in the molar series this tooth belongs. No surface shows contact with a tooth in front or behind. The determination of the dentition of Desmostylus is a matter of great interest. An examination of Yoshiwara and Iwasaki’s figures? shows that there is, in front of their first molar, a small tooth consisting of only four columns. In the skull from Oregon, which the writer described in 1915,2 there is in front of a molar (pl. 57, 23) apparently corresponding to that figured by the Japanese authors, and composed of the same number of columns, 8, the base of a smaller tooth which was regarded ‘as the first molar (pl. 57, 22). This supposed first’ molar, instead of being made up of eight columns, appears to have only five. The tooth in front of this (pl. 57, 21) is represented by the base of the crown and the root, and it has a diameter of 17 mm. On plate 58 of the paper cited, was presented the figure of a tooth which had four columns and which was believed to be the fourth premolar. This appears to correspond to the hinder premolar described by Yoshiwara and Iwasaki. Now, according to these identifications, the Oregon skull differs from the one found in Japan in having between the sup- posed last premolar with four columns and the molar with eight columns another tooth possessing apparently only five columns. It is improbable that the two species differed in such an important respect. An examination of my figure® shows that the molar indicated by 23 was emerging behind and above the supposed first molar 22. This tooth 22 can hardly be a premolar, for this might be expected to appear only after the molar behind it had come into action. One might insist also that it is not a milk tooth, because there appears to be no premolar to replace it, as shown by Yoshiwara and Iwasaki’s figure. Plate 2 of the Japanese authors shows that another molar (their M?) was moving downward and forward to take its place against the molar then in action—that is, it appears that the upper molars, on coming into place, move downward and forward as in the mastodons and elephants. If, now, we grant that, as the supposed first molar (22) of the Oregon specimen became worn down, the next molar (23) moved forward, pushed it out, and took its place, the condition seen in Yoshiwara and Iwasaki’s specimen would be produced. According to this interpretation, the hinder premolar of the paper last cited OS See 1 Journ. Coll. Sci., Japan, Imp. Univ., vol. 16, 1902, pl. 2; pl. 3, fig. 4. 2 Proc. U. S. Nat.

THE GENERA DESMOSTYLUS AND CORNWALLIUS—HAY. 3 would be the fourth premolar and the tooth immediately behind it the second molar, while the molar shown at a distance behind would be the third. In 19234 the writer proposed the new name Cornwallius, based on _ Desmostylus sookensis Cornwall.2 Through Director Francis Ker- mode, of the Provincial Museum of Natural History, Victoria, Brit- ish Columbia, the writer received for examination both of the teeth figured by Cornwall. These teeth are illustrated on the plates (pl. 1, figs. 4, 5, and pl. 2, figs. 1-5). It has occurred to the writer that these teeth may be milk teeth of Desmostylus and that the larger one (pl. 1, figs. 1, 2, pl. 2, figs. 4,5) may correspond to that called in my paper of 1915 the first molar. The tooth is of appropriate size. The length is 48.5 mm., the width 34mm. The corresponding dimensions of what the writer regarded as the first molar ® were estimated to be in length 40 mm., and width 28 mm., but the measurements were taken at the somewhat narrowed base of the tooth. The low crown of the tooth of C. soo- kensis accords with the idea that it is a milk tooth. it seems certain that the tooth which in my paper of 1915 (pl. 57) was designated by the numeral 27 is either a milk molar or the pre- molar which would follow it; also that 1t corresponds in position to the tooth Pm of Yoshiwara and Iwasaki’s plate 2, and to the small tooth of their plate 3, figure 4. The Oregon skull belonged evi- dently to a younger animal than did the Japanese skull. In the latter it seems that the premolar, if such it is, had not yet been pushed out to the level of the molar behind it. In the Oregon speci- men it is possible that the milk tooth 27 had not yet been replaced. As already said, the tooth designated 23 was lying immediately above the greater part of the tooth 22. The former might, there- fore, be taken as fourth premolar. Because of the great size of the tooth and the number of its columns, this appears wholly unlikely. The tooth 23 must be a molar. We may possibly get an explanation of the dentition of Desmo- stylus from that of the mastodons. In some of these the premolars are retarded in their development, in others even wholly suppressed. ‘he suppression of premolars began with the hindermost one. The same modification of the dentition has been demonstrated in the Szrenia. In the earliest members of the group, as Protosiven frassi,' the tooth formula was the typical one, 1. 3, c. 1, pm. 4,m. 3. Accord- ing to Andrews® the dental formula was the same in Hotherium aegypticum. Abel tells us that since the middle Eocene there has 4Pan-Amer. Geologist, vol. 39, p. 106, text-fig. 4. 5 Canad.

In Halithe- rium the hindermost premolar was not developed, and the corre- sponding milk tooth assumed the form of a molar. We may then regard it as possible that the tooth 22 of my plate 57 is a milk tooth which was assuming the form of a molar, and which was not to be displaced by a premolar, but by the first molar. The tooth in front of it is then the third premolar, or the corresponding milk molar. A deep pit in front of it represents the second pre- molar or milk molar, and a minute pit in front of that represents the first juvenile tooth. As to the tooth on which I based the genus Cornwadllius it is then possible that it is the hindermost milk tooth of Desmostylus,; but this is for the future to determine. I proceed to give a description of it: ‘The tooth (pls. 1, 2, figs. 4, 5) has suffered some loss of enamel on two columns, as shown by the figures. All of the columns have suffered some wear, but that they were of small height originally is evident. In two of them the wear had not reached the core of dentine. The columns taper rapidly from the base to the summit. Text figure 1 presents a view of this tooth before a fragment of the second inner column had been cemented in its place. It shows that Fic. 1.—Toorn or Cornwatrius the dentine core, broad at its base, SOOKENSIS. VIEW FHOM INNER tapers rapidly to its summit, as was necessary in a low-crowned tooth. As seen from the figures, there are in front two large columns, and be- lind these two somewhat smaller ones. At the rear is a column of which a part is gone. It appears quite certain that the snag of enamel at the right of the gap (pl. 1, fig. 4) formed part of a cusp which adhered to the hinder column. Whether it could be counted as the sixth column is doubtful. The tooth is taken to belong in the right maxilla. The length, measured in the axis of the tooth, is 45 mm.; the total length 48.5 mm.; the greatest thickness, 34 mm.; the height of the crown in front, 23 mm. On the front end there is a cingulum which does not occupy the whole width of the tooth. At the inner end of this are two small cusps.. Rootward from the edge of this cingulum there is a surface 10 mm. long and 4 mm. deep, which is worn from contact with a tooth in front. Between the cingulum and the grind- ing surface there is on each of the two anterior columns an extensive worn surface. No such surface is seen on the hinder end of the tooth. The cingulum is not developed on the sides and rear of the tooth; but at the outer end of the first transverse valley there is a large tubercle, worn at the summit and showing a pit of dentine. At ART. 8. THE GENERA DESMOSTYLUS AND CORNWALLIUS—HAY. 5 the inner end of the same valley is a much smaller tubercle. A single tubercle appears at the outer end of the second valley and is closely applied against the hindermost column. The rear of this column is missing. There belonged to this tooth quite certainly two roots, but these are broken off (pl. 2, fig. 5). A considerable pulp cavity remains, 27 mm. long and 15 mm. wide. It is slightly constricted near the middle of the length, indicating thus the parting of the roots. From Director Kermode was received also the tooth which was described and figured in 1917°, as Desmostylus hesperus, and which Cornwall, in his paper cited, figured as Desmostylus sookensis. It was found in the sandstone cliffs near the mouth of Coal Creek, British Columbia, by Miss M. Egerton. It was sent to L. M. Lambe, paleontologist in the Geological Survey, Ottawa, whose remarks on it are published on the page above cited. Mr. Lambe identified it provisionally as the upper right first molar. He did this possibly relying on my identification of the first molar in my paper of 1915. The length of the tooth (pl. 2, figs. 1-8) is 33 mm.; the width 24 mm.; the height of the crown, 16 mm. It is somewhat more worn than the tooth described in the previous paragraph, but it is evi- dent that the columns were originally low. It had two well-devel- oped roots (pl. 2, fig. 3) of equal size. These are now broken off squarely just below the crown. The transverse diameters of these roots are close to 18 mm. At the plane of fracture they are not en- tirely separated from each other. The tooth is supposed to belong to the left side of the lower jaw, because the cingulum is better de- veloped on the left side of the tooth. It consists of six columns arranged in three transverse pairs. Of the anterior pair the inner column is the largest of all. The inner column of the third pair is very small and the wear had not exposed the dentine. Cornwall, perhaps correctly, did not count it as one of the columns. On the front of the tooth, in the midline, is a broad tubercle which may be regarded as a talon or a part of a cingulum. On the outer face there is a slight cingulum-like ridge at the bases of the two front columns. Between the second and third columns is a tubercle or cusp. On the inner face there is little or no trace of the cingulum. On the front end of this tooth there is an extensive surface polished by contact with a tooth in front. This begins at the level of the grind- ing surface and descends not only to the talon, but in a narrowing strip nearly to the base of the crown. Above the talon the polished surface is 15 mm. wide from side to side. A small polished surface is found on the hinder end of the tooth. ® Rep. Provincial Mus. Nat. Hist., Victoria, B C., for 1916, p. 42, pl. 9, figs. 2, 3. 6 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. This tooth does not agree in structure with any yet described. It most resembles the teeth described by Yoshiwara and Iwasaki’ as lower second premolars. In those teeth, however, there are three columns in the hinder transverse row. There are some reasons why the larger of the two teeth referred to Cornwallius sookensis can not be regarded as identical with the tooth 23 of the Oregon specimen. These are as follows: (1) The outer border of the Oregon tooth is straight; in the Vic- tcria tooth this border is strongly curved. (2) The transverse rows of columns in the Oregon tooth appear to be arranged more obliquely to the long axis of the tooth than in that from Victoria. (3) The hinder end of the Victoria tooth is considerably broader than in the one from Oregon. Until some lucky discovery shall decide the matter one way or the other, the writer proposes to maintain the genus Cornwallius and to regard the larger of the two teeth (pls. 1, 2, figs. 4,5) as an upper molar, and the smaller one (pl. 2, figs. 1-3) as a lower molar, not the hindermost. The larger tooth is taken as the special type of Cornwallius sookensis. The cliffs in the vicinity of Sooke, Vancouver Island, ought to be carefully and frequently searched for additional materials of this sirenian. In their description of the skull of Desmostylus Yoshiwara and Iwasaki attribute to Desmostylus two pairs of lower tusks and one pair of upper ones. The lower tusks projected some distance from the jaw. The upper tusks were said not to have yet come into full growth, only the left tooth being slightly visible beneath the ruptured surface of the maxilla. Their figure? shows what was seen of this tusk. In my description of Desmostylus from Oregon I referred to what seemed to be an upper tusk. Although this was said” to show only on the right side, there is on each side a projection at the front of the specimen which represents the same structure. As shown by my figures, a fragment of the snout about 30 mm. long had been broken off in exhuming the skull and had later been cemented in its place. Recently, wishing to come to a decision regarding this supposed tusk, the writer removed the fragment and cleaned off both surfaces of the break. The view presented was not satisfac- tory. The circumference of the supposed tusk could not be traced on the side next the mid-line. Next, the matrix was ground down and polished to see whether any structure was hidden. What was revealed is shown in figure 3 of plate 1. On each side there ap- 0 Pl. 3, figs. 2 and 3. . 11 Journ. Coll. Sci., Japan. Imp. Univ., vol. 16, 1902, pl. 1, Up I. Proc. U. S. Nat. Mus., vol. 44, p. 391. ART. 8. THE GENERA DESMOSTYLUS AND CORN WALLIUS—HAY. 7 peared a number of cell-like spaces separated by thin walls of bone. It is evident that we have here a section across the right and left maxilloturbinal bones. There is no trace whatever of any upper tusk. The writer is led, therefore, to question the existence of an upper tusk in the Japanese specimen. What the describers very naturally took to be a tusk may be only the sandstone cast of one side of the nasal cavity. Over the surface of the cast naturally adhered some flakes of bone. Had a section been made across this region, the maxilloturbinal would probably have been discovered. The for- merly supposed tusk of the Oregon specimen where it projects in front has the appearance of the end of a turbinal bone. In this specimen the bone seems to end a little behind the middle of the length of the nasal opening. Although in the Japanese specimen the supposed tusk is shown as continuing nearly to the front of the I'ig. 2.—SIDE VIEW OF SKULL OF DESMOSTYLUS HESPERUS.

Recently +8 in the discussion of the position and connections of the jugal bone in Desmostylus, the writer published a figure illus- trating the right side of the skull of the Oregon specimen. Through inadvertence the lower branch of the hinder end of the frontal bone was represented as cut off by a suture and was lettered os. This figure is here reproduced (text fig. 2) with the necessary correction. It will be seen that the jugal terminates at about the middle of the lower border of the zygomatic process of the squamosal. In his paper of 1923 just cited the writer proposed to divide the Sirenia into two suborders, Desmostyliformes and Trichechiformes. Some of the characters of the Demostyliformes may be expressed as follows: Postorbital part of the skull broad and depressed. Preorbital part narrowed and moderately decurved. Temporal ridges feebly 13 Pan-Amer. Geologist, vol. 39, p. 108, text fig. 5. 45554—25—-Proe.N.M.vol.65——11 8 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. developed.

FIsHEer Of the Bureau of Entomology, United States Department of Agriculture INTRODUCTION The present paper is the results of a study of the material of this family from the West Indies found in the collection of the United States National Museum, together with such material as could be borrowed from other sources. Specimens have been received at various times for identification, but since the material in the col- lection was mostly unidentified, the descriptions widely scattered, and the species of the family from that region having never been treated in a synoptical way, it seemed advisable to bring together as much material from other sources as possible, so that the subject could be treated in a more exhaustive manner, which would facili- tate the identification of material by future students. Three-fourths of the number of species of Buprestidae hitherto known to inhabit the West Indies have been studied by the writer in the preparation of this paper, the 21 species not seen by him, so for as known, are represented mostly by unique types which were not available for study. The adults of this family, although abund- ant in nature, are so agile that their capture by collectors are not frequent and the fauna here treated appears to have been greatly neglected, but by assembling material from a number of Museums and private collections, a fairly good representation has been brought together, so that in addition to the 80 species previously known, one new genus, and 26 more species are described as new. The Buprestidae of the West Indies have been treated by a number of authors in a general way. Jacquelin Duval was the first of these authors to consider this family from that regien? (published in French and reissued the same year in a Spanish edition), and records five genera and 12 species, 4 of which are described as new.

Dr. Juan Gundlach ® records the same number of genera and species from Cuba as Chevrolat, without describing any new species, but giving more definite localities for the species. The same author, in La Fauna Puerto Riquefia,® lists 2 genera and 4 species from Porto Rico. Charles W. Leng and Andrew Mutchler, in A Preliminary List of the Coleoptera of the West Indies as Recorded to January 1, 1914," list 24 genera and 66 species from that region, which are decreased by synonymy in their supplement to the above paper ® to 64 species. In the present paper are included 29 genera and 107 species. The term West Indies as used in the present paper includes the islands lying in the Caribbean Sea and Gulf of Mexico and may be divided into four groups. First the Bahamas, which consist of about 700 small islands, composed mostly of low lying heaps of calcareous shell and coral debris deposited on a submarine plateau of vast area, forming a submerged link with the mainland of Florida; second the Greater Antilles, including Cuba, Jamaica, Haiti, Porto Rico, and the Virgin Islands, of these Haiti is the center and summit of the Antillean Range, and from Mount Tina, which is 10,000 feet above the sea level, the Antilles slope gently down to western Cuba and Jamaica, and to the Virgin Islands on the east; third the Lesser Antilles, consisting of a large number of small islands lying in two rows, an outer row of limestone and coral inlets and an inner row of volcanic formation; and fourth a number of islands lying along the northern coast of South America, of which Trinidad and Tobago are the most important, and which in a remote period were severed from the continent by the wearing of the equatorial currents. These islands, with the exception of those along the northern coast of South America, are supposed to be of more recent formation than the portions of the adjacent continents.

These conditions offer a bewildering variety of tropical fauna, but whose distribution is by no means uniform. The low lying Bahamas provide little support for vege- tation and some are almost barren. Researches by Charles Simpson® and those of John Small? 7 have shown a close affinity between the fauna of the extreme southern part of Florida, the Florida Keys, and some of the Antilles, just as the fauna of the islands along the northern coast of South America is allied to that of the coast with which they were once connected. In the Greater Antilles the forests are tropical, in some parts con- sisting of various species of palms, mahogany, tree ferns, and various trees furnishing edible fruits, while on the upper slopes the fauna becomes more characteristic of the temperate zone, and up to an elevation of 4,000 feet are often clothed with pines; farther up, with increased precipitation, rank growth of deciduous trees appear, while the summits are thickly overgrown with ferns. Since the species are more or less limited in their distribution to certain islands, and on account of the great variety of plants and variation in the temperature, the family Buprestidae from this region should be exceedingly rich in species. Very little collecting has been done, especially in the mountainous sections, where are to be expected a number of new forms. This is especially true of the smaller species, which are mostly leaf and twig miners, and since these forms have been practically neglected by collectors, the number of species will be largely increased by careful collecting. As the descriptions of the species are widely scattered throughout various publications, some of which are not available to most stu- dents, each species is herein redescribed from specimens which are as nearly typical as is possible for the writer to determine from the descriptions. Where specimens of a species are not available for study, a translation of the original description is given. No attempt has been made to give a complete bibliography; only the more important papers and those which apply to the region cov- ered by the present paper have been cited. References to the species listed in the Leng and Mutchler Catalogue, which has been of the greatest aid to the writer, have not been cited under the species.

The writer greatly appreciates the loan of material during his study of this family and wishes to thank the following entomologists for their assistance: Nathan Banks, Museuin of Comparative Zool- ogy, Cambridge, Mass., for a collection made by Dr. W. M. Mann in Haiti; Dr. Henry Skinner, for a collection from the Academy of Natural Sciences of Philadelphia, containing the Poey collection from Cuba; Dr. W. J. Holland, for material from his private collec- tion, as well as for the loan of material from the Carnegie Museum of Pittsburgh, collected on the Isle of Pines and Jamaica; Prof. H. F. Wickham, University of Iowa, for material from the Bahamas and Haiti; and George N. Wolcott, of the Insular Experiment Station, Rio Piedras, Porto Rico, for material collected in Porto Rico. G. B. Merrill, Gainesville, Florida; E. G. Smyth, Bureau of Entomology, United States Department of Agriculture; and Frank B. Mason, Philadelphia, have also furnished valuable addi- tions to the material studied. Stephen C. Bruner, chief of the Department of Entomology and Vegetable Pathology, Estacion Ex- perimental agronomica, Santiago de las Vegas, Cuba, has sent an interesting collection taken in Cuba, and has also examined the material in the Gundlach Museum at Habana and furnished the writer with a list of the species contained in that collection. The writer is under great obligations to Dr. F. E. Lutz and A. J. Mutchler for the loan of a valuable collection from the American Museum of Natural History, including collections made by the ex- peditions conducted by that museum to the various islands in the West Indies, and also those made by the New York Academy of Sci- ences in conjunction with the museum, as well as other material col- lected by private individuals and sent to that museum for identifica- tion. I am especially indebted to Dr. Charles J. Gahan for the loan of material from the British Museum. ‘This collection con- tained many species which had been compared with the types of Thompson, Gory, Chevrolat, ete., by the late Charles O. Waterhouse, and has been of the greatest help in my studies. The writer desires to express his deep appreciation and sincere gratitude to Dr. E. A. Schwarz, of the United States National Museum, for the many helpful suggestions during the course of the work, for his kind and valuable criticism, and for aiding generally in every possible way in the preparation of this paper. CLASSIFICATION The family of Coleoptera treated in the present paper has been a great favorite with collectors on account of the large size and ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 5 splendid color of many of the species which compose it. The species are generally elongate and more or less cylindrical, although some are very robust and appear ungraceful in form, but this is compen- sated by the incomparable richness of their colors and markings, and for this reason they have been named “ Richards” by some of the older authors. The larvae are variable in form, and live in both living and dead plants, and the adults are found feeding on the flowers and foliage of various plants, or sunning themselves on the trunks of trees during the warmer part of the day. The genera as defined in the following paper may be tabulated as follows: KEY TO THE GENERA 1. Sternal cavity formed entirely by the mesosternum (tribe Polycestini)_ 2.

Body robust, oblong, more or less elongate, and attenuate in front and behind. This genus contains about 30 described species, which are all found in the Neotropical region, with the exception of one species from China and four from Africa. This paper includes 13 species, one of which is described as new, all having been recorded from the West Indies. The species of the genus resemble each other very closely, and considerable confusion has been caused by the erroneous identifica- tions of some of the older species by various authors. The species are not very well represented in collections, and until more speci- mens from exact localities are available for study, much doubt must still be attached to the names of several species. My studies of this genus has been made possible through the kind- ness of Dr. C. J. Gahan, of the British Museum, in loaning me a series of species, a number of which had been compared with the types of Linnaeus, Thomson, Gory, etc., by the late C. O.

Male.—Not seen. Length, 17-25 mm.; width, 5.5-8 mm. This species was originally described by Fabricius from a speci- men from South America in the Hunter collection. Thomson (1878) redescribed the same species under the name vesplendens from a questionable locality, probably Surinam or Brazil. Waterhouse (1904) examined the type of this species in the Hunter collection at the University of Glasgow, and also the type of vesplendens Thom- son in Oberthiir’s collection, and states that cyanipes Fabricius is the same as resplendens Thomson from Jamaica. The following material has been examined. Coll.

Pronotum strongly transverse, two times as wide as long, only slightly narrower in front than behind, and widest just behind the middle; sides obliquely expanded from the apical angles to just behind the middle, where they are broadly rounded, then more obliquely attenuate to the posterior angles, which are rather acute and covered by the elytra; anterior margin deeply arcu- ately emarginate, with a broadly rounded median lobe; base bisinu- ate with the median lobe strongly angulated; disk with a feeble median depression, which is more deeply impressed near the scu- tellum, and in some specimens feebly longitudinally grooved ; surface coarsely and deeply punctate, the punctures denser here and there, and becoming coarse and confluent on the sides, more remotely placed on the disk, where there are two large triangular opaque spaces, which are very sparsely punctate, and separated from each other by the median depression, the surface sparsely clothed with a few very short, inconspicuous hairs.

Female.—Differs from the male in being larger and more robust, the abdomen beneath more sparsely punctured and less pubescent, and the first abdominal segment feebly convex and smooth at the middle. Length, 15-22 mm.; width, 5.5-7.5 mm. This species was described by Chevrolat (1838) from Cuba, and its distribution is probably restricted to that island. Jacquelin Duval (1857) simply records it from Cuba, and Chevrolat (1867) states that it is found in the eastern and central part of the island, and that specimens are in the collections of Gundlach, Poey, and Chevrolat. Gundlach (1891) records it from the eastern part of the island. The following material has been examined: Coll. British Mus.: One male labeled “ Cuba (Coll. Chevrolat)” and marked type. Coll. Amer. Mus. Nat. Hist.: Male and female collected on the San Carlos Estate, Guantanamo, Cuba, June 18, 1916, by Chas. T. Ramsden. Coll. Acad. Nat. Sci. Philad.: One female labeled Cuba (Poey Coll. No. 339). Coll. U. S. Nat. Mus.: Male and female collected on the San Carlos Estate, Guantanamo, Cuba, June 18, 1916, by Chas. T. Ramsden. (Donated by the Amer. Mus. Nat. Hist.) There is also a single specimen of this species labeled No. 861 in the Gundlach Collection in Havana which has not been examined by the writer. This species is easily separated from the other species of this genus found in the West Indies by the two subopaque spots on the pronotum.

Female.—Differs from the male in having the first abdominal segment feebly convex and without the densely punctured and pubescent median spot. Length, 16 mm.; width, 7 mm. This species was described by Castelnau and Gory (1837) from Cayenne, Guiana, as depressa, but since this name had been used previously by Linnaeus for a species of this genus from South America, Saunders (1871) proposed the new name gory. The species has also been described by Thomson (1878) from Colombia as solierit, and the second time in the same paper from Caracas, Venezuela under the name of cribrata. Waterhouse has examined the types of solieri and cribrata in the Oberthur collection and finds that they are identical with the species described by Castelnau and Gory as depressa, and later changed by Saunders to goryz. This is the species recorded by Prof. H. F. Wickham (1895) from the Bahamas as probably velasco Castelnau and Gory. The above description was made from a male specimen from Venezuela, kindly loaned by the British Museum, and which was compared wtih the type of cribrata by Waterhouse, and with which it agrees. Leng and Mutchler in their List of the West Indian Coleoptera? record it from the Antilles, and there is a single male specimen in the Coll. U.S. Nat. Mus., received from H. F. Wick- ham, labeled “ Water Cay, Bahamas” which does not differ from the specimen from which the above description was made. In the Coll. Acad. Nat. Sci. Philad., there is a single female labeled “ Cuba (Poey Coll. No. 347)” which is slightly narrower than the other specimens examined. This is one of the shortest oblong species found in the West Indies. It is entirely black above, equally rounded in front and behind, and each elytron with five distinct costae, including the scutellar one.

Thorax not quite twice as broad as long, black, dull, broadest behind the middle, strongly angular at the sides, obliquely narrowed in front and behind ; the space from the lateral angle to the base rectilinear. The punctua- tion strong and sharp; the punctures in the discoidal impression (which is very shallow and ill defined) moderately large and very slightly separated, at the sides they are smaller and crowded together. There are two small spaces at the base which have only a few punctures. The elytra are rusty brown, the margin and costae blackish. There are four smooth costae, the first abbreviated before the middle, the second and third well marked, the fourth fine and abbreviated at the base and apex. The double lines of foveae between the suture and second costa and the second and third costae are regular and the foveae are subquadrate. The foveae which form the more lateral lines are regular, but a little less quadrate. Viewed beneath, the lateral ridge of the thorax is very sharp. The whole under side is clothed with a fine, grey pubescene. The abdomen is very distinetly and rather closely punctured. There is an oval, brown, pubescent spot on the basal segment. Long. 14 mm. Hab. St. Domingo (or possibly Dominica). This species is very close to P. Chevrolati, but is smaller, and the lines of punctures on the elytra are very regular. A single specimen from an old collection, with the locality indistinctly written. The type of this species is in the British Museum, and since I have been unable to examine it, the species is given its position in the key solely from the characters given in the original description.

The following is a translation of Thomson’s original description: Polycesta chevrolatii (Guérin Mss.) Thomson.—Habitat: Cuba. Length, 21-26 mm.; width, 814-11 mm. Form of P. thomae Chev- rolat, but entirely black. Head granulate-punctate. Prothorax with the sides strongly dilated behind the middle, feebly depressed at middle, with a feeble longitudinal line at the base; surface punctate, the punctures coarse and densely placed at the middle and sides. Elytra carinate-fossulate, the fossae densely placed and generally subelongate; sides toward the apex denticulate, with apex bispinose. Body beneath and legs sparsely punctate. Allied to P. thomae Chevrolat, but differs from it: first by the general appearance (livrée) ; second, by the prothorax being straight anteriorly and not as strongly punctured; third, by the fossae on the elytra generally elongate, and finally by the underside less densely punctured. There is a single specimen of this species in the British Museum, but it has not been examined by the writer. The species was un- known to Kerremans, as he simply quoted Thomson’s description in his Monographie des Buprestides. 16 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 POLYCESTA PERFECTA Kerremans Polycesta perfecta KERREMANS, Mon. Bupr., vol. 7, 1914, pp. 257-258. The following is a translation of Kerreman’s original description: Length, 24 mm.; width, 9 mm. Elongate, attenuate behind, slightly convex, entirely black above, with a very feeble purple re- flection on the elytra, turning to blue along the suture; beneath black with a slight bronzy tinge, pubescence of a dull reddish color, with the tibiae and tarsi bluish. Remarkable for the regularity and dis- tinctness of the elytral structure. Head rugous, with irregular vermiculate reliefs. Pronotum wider than long, narrower in the front than behind, widest behind the middle; anterior margin trun- cate; sides strongly obliquely converging to the front, rounded just behind the middle, then sinuate and less converging to the base, with the posterior angles small, feebly projecting externally and feebly depressed on the humeral angles of the elytra; base bisinuate; middle of disk depressed; surface covered with round punctures, rather closely and unequally spaced, more unequal and irregular near the anterior angles, where the intervals form a network of irregular areas. Scutellum small, wider than long. Elytra feebly lobed and transversely impressed at the base, nearly parallel on the sides to the posterior third, then regularly arcuately attenuate to the tip, which is armed with teeth, unequal in length, and densely and irregularly placed between the suture and the sixth row of punctures; surface covered with rows of coarse, transverse, subrectangular punctures arranged in very regular double rows, and separated by smooth, feebly costiform lines. Beneath finely and unequally punctate, the punctures much finer and denser along the external margins of the abdominal segments; legs slightly robust, femur nearly smooth, the punctures fine and widely separated, tibiae a little more coarsely and densely punctured. Habitat: Jamaica (Kerreman’s Collection). No specimens have been seen by the writer which would agree with the above description, so the species has been placed in the key solely upon the characters given in the original description.

The following is a copy of Waterhouse’s original description : Hlongate-oblong, much flattened; green; elytra ferruginous, shaded with green at the suture. Thorax at the widest scarcely wider than the elytra, only slightly angular at the sides, obliquely narrowed in front, very slightly narrowed posteriorly; green, shaded with purple-coppery at the base. Disk lightly impressed; the punctures rather coarse, very close, and rather confused, rather smaller at the sides, with two spots at the base which have only a few punctures. Elytra subparallel, with a not very distinct costa near the scutellum extending about a quarter the length of the elytra. There are two other very distinct smooth costae. The foveae which form the double lines are very regu- lar and somewhat round. Beyond the second complete costa there are four rows of regular somewhat round foveae or large punctures. The underside is a ART. 9 WEST INDIAN BUPRESTIDAE—FISHER at beautiful bluish green, the legs, parts of the sternma, and margins of the seg: ments shaded with purple. Tarsi cyaneous. The abdomen has some fine greyish pubescence, and on the basal segment there is a brown velvety spot. Long. 11 mm. Habitat: Jamaica (Gosse). This species is very near P. velasco Laporte and Gory, but that has a rather more angulated thorax, ete. It is possible that velasco and montezuma Laporte and Gory, may be sexes of the same species, but there is not material at hand to enable me to decide. The type of this species is in the collection of the British Museum and has not been examined by the writer, but is included in the key from the characters given in the original description.

This species is described from a single female collected at the type locality during May or June, 1917, by William M. Mann. It is one of the most slender species of the genus and can be readily separated from all other Polycesta found in the West Indies by the coloration, and by the posterior angles of the pronotum being broadly rounded and not fitting closely to the base of the elytra.

Chevrolat (1867) records it from the central part of the same island from material in the collections of Gundlach, Poey, and Chevrolat. Gund- lach (1891) records collecting specimens at Cienfuegos, and also at Caimanera near Guantanamo, both localities in Cuba. Material has been examined of this species as follows. Coll. British Mus.: Two females, one labeled “ Cuba (Poey)” and marked type, the other simply labeled “ Parry (Saunders 74-18).” Coll. Acad. at. Sci. Philad.: One female, Cuba (Poey Coll.). Coll. Amer. Mus. Nat. Hist.: One female, Guantanamo, Cuba, collected June 11, 1910, by Chas. T. Ramsden. Coll. U. S. Nat. Mus.: One female, Guantanamo, Cuba, collected June 26, 1915, by Chas. T. Ramsden. (Donated by Amer. Mus. Nat. Hist.) There is also a specimen in the collection of the Acad. Nat. Sci. Philad., labeled “Cuba (Poey Coll.)” which I have placed under this species. It is a very small specimen measuring only 11 millimeters in length and 4.5 millimeters in width, and which agrees in every way with the other specimens of this species examined, except in size. It is a male and has the usual densely punctured and pubescent median spot on the first abdominal segment. There is a single example labeled No. 807 in the Gundlach Museum in Havana which has not been examined by the writer. Kerremans has placed this species as a synonym of excavata de- scribed by Blanchard (1846) from Argentine Republic, but since these localities are so widely separated and the species has not been reported from any intermediate localities, I am retaining the name angulosa for the specimens collected in Cuba. This species is closely allied to porcata Fabricius, but it is more slender, head more densely and coarsely punctured, anterior margin of pronotum not as deeply emarginate, abdomen beneath more finely punctured and more densely pubescent, prosternum more densely punctured, and the prosternal process much narrower in proportion to its length than in porcata. | ——= arT. 9 WEST INDIAN BUPRESTIDAE—FISHER 23 POLYCESTA OLIVIERI Waterhouse Buprestis depressa Outvier (not Linnaeus), Entomol., vol. 2, gen. 32, 1790, pp. 39-40 (part), (name preoccupied).

Male.—Not seen. Length, 20-24 mm.; width, 6.5-8 mm. Olivier (1790) had before him more than one species when he re- described Buprestis depressa Linnaeus, but his figure is certainly that of depressa and he records specimens from South America, Antilles and Cayenne in the British Museum. Waterhouse (1904) states that the species described by Olivier as depressa is not the one described by Linnaeus under that name. so he proposes the new name oliviert for it, and states that there is in the British Museum a very old specimen bearing the name depressa which he believed is certainly the one mentioned by Olivier. At least some of the specimens which Olivier had before him were the true depressa as his figure and description applies to that species and not to the one which Waterhouse has given a new name. Waterhouse further states that the old specimens in the British Museum are without locality, but recent examples in the Museum and in Oberthiir’s Col- lection are from Jamaica. I have been able to examine two females from the British Mu- seum Collection, labeled simply Jamaica, and from which the above description was made. (One of these specimens has been donated to the United States National Museum collection.) This species resembles angulosa Jacquelin Duval, but it is more flattened above, without scutellar costae, and the elytral punctures are much finer. From depressa Linnaeus and thomae Chevrolat, which also have the scutellar costae absent, it can be separated by the longitudinal costae on elytra not as distinctly elevated and the punc- tuation much finer. 4 7 4 ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 25 POLYCESTA DEPRESSA (Linnaeus) Buprestis depressa LINNAEUS, Mant Plant., vol. 2, 1771, p. 533.—Ortvirr, Entomol. vol. 2, gen. 32, 1790, pp. 39-40 (part).

Male.—Not seen. Length, 18-24 mm.; width, 7-8.5 mm. This species was originally described by Linnaeus (1771) from “ Oriente.” Olivier (1790) gives a figure of this species and records it from South America, Antilles and Cayenne, and states that speci- mens are in the British Museum. It is the species listed and figured by Herbst (1801) as porcata from Cayenne, Guiana, and the Antilles, and also by Castelnau and Gory (1837) under the same name from Guadeloupe. Chevrolat (1838) described this species as karakera from specimens collected at Pointe-a-Pitre, Guadeloupe, by Doctor Lherminier, and which he says is the same species figured by Castel- nau and Gory as porcata, but is not the species described by Fabricius under that name. Fleutiaux and Sallé (1890) record specimens collected at Vieux Fort, Guadeloupe, by Vitrae on a climbing shrub (Tecoma pentaphylla). Kerremans (1906) records it from Cayenne, Santa Lucia, and Guadeloupe in the collection of the Paris Museum. Through the kindness of the British Museum I have been able to examine two females from their collection, one labeled Antilles (Fairmaire) which had been compared and agrees with Luprestis depressa in the Linnean Collection by C. O. Waterhouse, and from which the above description was made; the other specimen is with- art. 9 WEST INDIAN BUPRESTIDAE—FISHER OT out locality, but is labeled “ karakera Chevr., compared with type (Saunders 74-18).” This specimen is more coarsely punctured, more brightly colored and more acuminate posteriorly, otherwise the two specimens are identical. This species resembles thomae very closely, but it is more slender, more brightly colored, more acuminate posteriorly, and the elytral costae are more strongly elevated.

Male.—Not seen. Length, 20-25 mm.; width, 8-9.5 mm. This species was described by Chevrolat (1838) from the island of St. Thomas. Kerremans (1906) records specimens from the same island in the collection of the British Museum and also in the Pariz Museum. Kerremans has placed this species as a synonym of por- cata Fabricius, but Waterhouse (1904) writes that the type of thomae is in the collection of the British Museum, and that it is distinct from porcata. I have examined two females of this species, one from the collec- tion of the British Museum simply labeled St. Thomas; the other in the collection of the American Museum of Natural History, from the same locality, collected during July, 1915, probably by C. Shoe- maker. After carefully examining the above specimens, I agree with Waterhouse that it is distinct from porcata. The punctuation on the elytra is finer and more regular, the four costae on disk are distinctly elevated, and the scutellar costae are entirely absent.

Antennae rather short, first joint long, feebly arcuate, and clavate at apex, second, third, and fourth short, sub- globular, and subequal in length, fifth to tenth serrate, wider than long (sometimes serrate from the fourth joint), the eleventh joint oval. Eyes large, narrowly oval, feebly convex, parallel, or at most only obseletely more widely separated on the vertex than at the front. Pronotum strongly transverse, variable in shape, often wider than the elytra, depressed, suleate or convex at the middle, truncate at the base, which is longitudinally striate along the entire width. Scutellum not visible. Elytra variable in form, rounded or acumi- nate at the apex, with the sides serrate posteriorly. Sternal cavity formed entirely by the mesosternum, which is entire and emarginate in front. Prosternum wide, flat or convex, the anterior margin sinuate, emarginate, truncate, or lobed at the middle, and the proster- nal process usually broadly rounded at apex. Posterior coxae dilated internally. Legs rather short and slender; tarsi rather robust, the fifth joint nearly as long as the preceding joints united; tarsal claws dentate. This is a very large genus and at present contains about 300 species, which are distributed throughout the warmer regions of the entire world, with the exception of Australia, where they are re- placed by the genus Stigmodera. The present paper includes species, 4 of which are described as new. The adults are usually found feeding on the pollen of various flowers, and since the color markings are so variable in some species, they are exceedingly difficult to identify. The species of this genus can be readily separated from all other West Indian Buprestidae by the scutellum being invisible. KEY TO THE SPECIES 1.

This is an elongate subcylindrical species and can be separated from all other West Indian species of this genus, except jamaicensis, by the antennae being serrate from the fourth joint. From jamai- censis it differs in having the yellow elytral spots arranged in two longitudinal rows, one along the lateral margin, the other near the suture. ACMAEODERA JAMAICENSIS, new species Male—Narrowly elongate, subcylindrical, rounded in front, more acuminate posteriorly and feebly flattened above (nearly straight below and feebly arcuate above when viewed in profile) ; head and pronotum black, with a feeble aeneous tinge, the latter with a large triangular reddish-yellow spot, situated on each side at the posterior angles, extending internally for about one-third of the width of the pronotum, and along the lateral margin to near the apical angles; elytra black, with a slight purplish tinge, and each elytron ornated with yellow markings as follows: A small spot at base near scutellum, a large oblong area along lateral margin, extending from humerus to middle, and internally to about the middle of the elytron, and enclosing an oblong dark spot, a transverse fascia at apical third, an oblique one just behind it, and a small round spot at the apex; beneath aeneous, with a strong purplish tinge and more shining than above.

Pronotum rather strongly transverse and moderately convex, nearly two times as wide as long, apex and base nearly equal in width, widest just behind the middle with a small foveate depression in front of the scutellum, and on each side in the yellow area a similar but deeper depression, situated a short distance from the base, there is also a broad obsolete depression extending from this fovea obliquely for- ward toward the lateral margin; sides arcuately rounded, slightly more obliquely in front than behind, the margins narrowly flattened and only partially visible from above; anterior margin feebly arcuately emarginate, with a distinct angulated median lobe: base ART. 9 WEST INDIAN BUPRESTIDAE—FISHER aa transversely truncate; surface densely and very coarsely punctate, the punctures shallow, irregular, and nearly confluent, the sides forming a network of polygonal areas, bottom of punctures smooth and from each arises a short erect inconspicuous hair.

Length, 7.5 mm.; width, 2.75 mm. Type locality —Jamaica. Type—British Museum. This species is described from a single male received through the kindness of the British Museum. It is simply labeled Jamaica with- out any additional data and was received under the manuscript name jamaicensis, which I have retained for the species. It is one of the elongate subcylindrical species and can be sepa- rated from all the other West Indian species of this genus, except subcylindrica Fisher, by the antennae being serrate from the fourth joint. From that species it can be distinguished by the yellow elytral markings, which are not broken up into two longitudinal rows of small spots, but has a large lateral area behind the humeri enclosing a dark spot and with transverse fasciae toward the apex. 34 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 ACMAEODERA MARGINENOTATA Chevrolat Acmaeodera marginenotata CHEVROLAT, Ann.

Length, 7.5 mm.; width, 3.5 mm. Described by Chevrolat (1867) from Cuba and recorded by him from the central part of the island, from material in the collections of Gundlach and Poey. Gundlach (1891) reports collecting it on the flowers of a shrub at Caimanera and Cienfuegos. WKerremans (1906) records it from Cuba but states that the species is unknown to him. This species is not represented in the Poey collection in Philadelphia, but there is a single example labeled No. 809 in the Gundlach Museum in Habana, which has not been available for study. This species seems to be very rare in collections and I have not seen any specimens of it from the West Indies, but there is a specimen in the United States National Museum from Key Largo, Florida, which agrees with the description given by Chevrolat, and from which the above description was made. It is a very distinct species. extremely coarsely and deeply punctate, sides of the elytra strongly deflexed at lateral margins, humeral angles produced into a narrow lobe, and with a large yellow basal spot at middle of the first abdo- minal segment. In the specimen examined the elytra seem to be connate, as no suture could be seen between the two elytron, but on account of it being a unique specimen, no dissections could be made. This is the specimen recorded by Fall (1899) as cubaecola Jacquelin » Duval, based on an identification made by Linell. 86 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 ACMAEODERA FLAVOMARGINATA (Gray) Buprestis flavomarginata Gray, Griffith’s Anim.

Elongate, feebly triangular, broadly rounded in front, more ac- cuminate posteriorly, and feebly flattened above (nearly straight be- neath and moderately arcuate above when viewed in profile) ; pice- ous, with a slight aeneous tinge; pronotum with a lateral yellow longitudinal band, not quite touching the lateral margin, and some- times abbreviated anteriorly; elytra without @iscal markings, but with a yellow marginal band extending from the humeri to a little behind the middle, and becoming slightly wider posteriorly, and with two transverse reddish or yellowish fasciae near the apex, the two fasciae sometimes connected, forming a broad band, and enclos- ing one or more small dark spots; beneath more shining than above. Head nearly flat, with a broad, moderately deep, oval depression on the front, and forming two more or less distinct elevations; occiput with a longitudinal carina extending to the frontal depres- sion; surface densely and coarsely punctate, the punctures rather deep, irregular, and nearly confluent, the sides forming a network of polygonal areas, bottom of punctures smooth and from the center of which arises a long erect inconspicuous hair; epistoma broadly and deeply triangularly emarginate in front, with the lateral angles broadly rounded; antennae serrate from the fifth joint. Pronotum strongly transverse and moderately convex, two and one-half times as wide as long, distinctly narrower in front than behind, widest at basal sixth, with a large, rather deep median depression, which is broader posteriorly, and with a small very deep depression on each side near the base, about midway between the middle and lateral margin; sides obliquely expanded from apical angles to basal sixth, where they are arcuately rounded, the margins rather broadly flat- tened and visible from above; anterior margin deeply arcuately emarginate, with a broadly rounded lobe at the middle; base trans- versely truncate, the posterior angles obtusely rounded; surface densely, coarsely and regularly punctate, the punctures well sepa- rated on the disk, but becoming denser and more confluent toward ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 37 the sides, and from each puncture arises a long erect inconspicuous hair. Elytra slightly flattened on disk, not quite as wide as pro- notum; humeral angles obtusely angulated; sides feebly obliquely narrowed to behind the middle, then arcuately attenuate to the tips, which are conjointly acutely rounded, the lateral margins coarsely serrate posteriorly ; humeri strongly developed ; surface striato-punc- tate, the striae impressed, nearly as wide as the intervals on the disk at base, becoming much narrower toward the apex, and rather widely separated at the sides, the striae punctures deep, coarse, and sepa- rated by about their own diameter, becoming finer and more oblong toward the apex; intervals flat on the disk, more convex laterally, with a single row of distant minute punctures, from which arises a rather long erect inconspicuous hair, the fifth interval costate, sometimes obsolete apically, but it is always distinct at the base. Abdomen beneath rather densely but not coarsely punctate, the punc- tures shallow and open posteriorly, and sparsely clothed with long inconspicuous hairs, the intervals smooth and shining; last ventral segment broadly rounded at apex, without a distinct subapical carina. Prosternum more coarsely and deeply punctate than the abdomen; anterior margin feebly arcuately emarginate at the middle, with a distinct lobe on each side of the emargination; prosternal process parallel to behind the anterior coxae, nearly three times as wide as the coxal cavity, and feebly broadly rounded at apex. Length, 8-13 mm.; width, 3.2-4.75 mm. This species was described originally by Gray (1882) from Brazil. Saunders (1871), and Fleutiaux and Sallé (1890) record it from Guadeloupe. Waterhouse (1889) described the same species from Mexico as prowima, and Kerremans (1897) also described the species from Guadeloupe under the name of contigua. Only two specimens of this species from the West Indies have been examined, and both of these were received from the British Museum, one labeled “ Guade- loupe (Fairm),” the other Guadeloupe (Plason) and labeled type of contigua Kerremans. The species is widely distributed from Texas southward to Brazil, but so far, has only been recorded from one of the West Indian Islands. In a species so widely distributed, a great variation would naturally be expected, but the only variation seen in a series of specimens examined from widely separated regions, is that of the transverse reddish or yellowish fasciae near the apex of the elytra, and which has caused it to be described under a number of different names. In some specimens the two fasciae are distinctly separated, while in others they are more or less connected, forming a broad band and enclosing one or more small dark spots. 38 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 ACMAEODERA CRUENTA (Olivier) Buprestis eruenta Oxivier, Entomol., vol. 2, gen. 32, 1790, pp. 48-49, pl- 3. fig. 21.

Length, 8-11 mm.; width, 4-5 mm. Originally described by Oliver (1790) from Santo Domingo. Mannerheim (1837) records it from the same island on the foliage of Crotinus cascarillae, and from all accounts the distribution of this species is restricted to that island. The following material has been examined. Coll. U. S. Nat. Mus.: One specimen from Port-au-Prince, Haiti (W. L. Rockwell), and another one from the same locality collected by R. J. Crew, and received from H. F. Wickham. Coll. British Museum: One specimen, Haiti (Saunders 74-18) ; one labeled simply St. Domingo, and a third specimen, labeled Haiti (Mus. Paris, Chevrolat Coll.). In size and form this species resembles pulcherrima Jacquelin Duval, but it can be easily separated from that species by the elytra having the apex fiery red, and the yellow markings arranged in two longitudinal rows on each elytron.

Length, 8.5-10 mm.; width, 2.75-3.5 mm. Described by Jacquelin Duval (1857) from Cuba. Chevrolat (1867) records it from the eastern part of the same island from ma- terial in the collections of Gundlach, Poey, and Chevrolat. Gund- lach (1891) records collecting it on a flowering shrub at Caimanera, Cuba, during July. Kerremans (1906) has placed cubaecola listed by Fall** from Key Largo, Florida, and pulcherrima by the same author 74 from Metacumbe Key, Florida as synonyms of cubaecola, but the one listed by Fall as cubaecola is the species described by Chevrolat as marginenotata. T have been able to examine two specimens of this species from the collection of the Academy of Natural Sciences, labeled Cuba (Poey Coll. No. 348), which agree with the original description, and from which the above description was made. (One of these specimens has been donated to the U. S. Nat. Mus. Coll.). There are also two examples of this species labeled No. 1419 in the Gundlach Museum in Habana, and a single example in the British Museum, which have not been examined by the writer. The species is closely related to confusa Fisher, but is more par- allel and subcylindrical, more convex above, pronotum not sulcate at base, and the markings on the elytra are more irregular and not ar- ranged in two longitudinal rows of distinct round spots. ACMAEODERA CONFUSA, new name There seems to have been considerable confusion in the identifica- tion of this species by Kerremans, since pulcherrima and cubaecola listed by Fall are two radically different species, but neither one is the species described by Jacquelin Duval as cubaecola. Kerre- mans probably did not see the true cubaecola from the Antilles, as he redescribed and figures specimens from the Fenyes collection from Key Largo, Florida, which are identical with the specimens listed by Fall as pulcherrima from Metacumbe Key, Florida. For the one described and figured by Kerremans as cubaecola and listed by Fall as pulcherrima, I therefore propose the new name confusa. 18 Journ, N. Y. Ent.

Length, 9-12 mm.; width, 4.5-5.5 mm. This species was described by Jacquelin Duval (1857) from Cuba. Chevrolat (1867) records it from the central and eastern part of the same island, from material in the collections of Gundlach, Poey, and Chevrolat. Gundlach (1891) records collecting adults on the flowers of a shrub at Caimanera and also at the Bay of Guantanamo, Cuba. Fall (1899) records three specimens of this species in the collection of the United States National Museum from Metacumbe Key, Florida, based on identifications made by Linell. These specimens are not the species described by Jacquelin Duval as pulcherrima, but are confusa Fisher. Kerremans (1906) records it from Cuba, in the collection of the Brussels Museum. Specimens have been examined from the following Cuban locali- ties. Coll. U. S. Nat. Mus.: One specimen, Santiago (J. M. Espin). Coll. Amer. Mus. Nat. Hist.: One specimen, Rio Seco, San Carlos Estate, Guantanamo (Chas. T. Ramsden). Coll. British Mus.: One specimen, Cuba (Coll. Chevrolat); and another one without a lo- cality, and simply labeled “ Saunders 74-18.” Coll. Acad. Nat. Sci. Phila.: Two specimens, Cuba (Poey Coll. No. 931). There are also two specimens labeled No. 808 in the Gundlach Museum in Habana, which have not been examined. There has been considerable confusion in regard to the identifica- tion of this species and cubaecola, but the two species are distinctly different, pulcherrima is a very broad, triangular species, with the pronotum widest at base, while cubaecola is narrow, elongate, and subcylindrical, the pronotum widest at middle or basal third, the sutural intervals broadly expanded on basal half, and the color mark- ings on the elytra are differently arranged. 44 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 ACMAEODERA WICKHAMI, new species Acmaeodera cubaecola WickHAM, Canad.

Head rugose, sometimes feebly depressed, and wider in front than on the vertex; front not narrowed by the insertion of the antennae; epistoma short, broadly and rather deeply emarginate in front; antennal cavities small, triangular, and armed posteriorly by a strongly elevated, oblique carina, and situated at some distance from the inner margin of the eyes. Antennae moderately long; first joint rather short and robust; second and third very short, globular more slender than the first, the third sometimes slightly longer than 48 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 ; the second; fourth and fifth elongate about equal in length, the fifth sometimes feebly enlarged and angulated at the apex; sixth to tenth moderately dentate on the inner side and subtriangular; eleventh oblong and rounded at apex; the dentate joints armed with pori- ferous pores and foveae on both sides of the joints. Eyes large, elliptical, strongly convex, and slightly closer to each other on the vertex than at the front. Pronotum wider than long, variable in shape, base bisinuate, and the surface sometimes with smooth shining areas. Scutellum very small and rounded. Elytra very variable, base sinuate, sides smooth posteriorly, sometimes dentate, with the apex emarginate, bidentate or obliquely truncate. Sternal cavity formed by the mesosternum and metasternum; mesosternum divided, the lateral branches long and feebly oblique; metasternum truncate in front, only feebly emarginate at middle, and with a narrow longitudinal median groove on the disk. Prosternum variable; anterior margin truncate, sinuate or lobed; prosternal process rather broad, feebly convex and with a groove along the lateral margins. Abdomen with the first segment broadly sulcate at middle. Posterior coxae strongly dilated internally, the anterior margin sinuate, and the posterior margin more or less emarginate on the interior dilated part. Legs feebly robust; anterior and middle femora feebly swollen at middle, the posterior ones subcylindrical and feebly flattened on both sides; tibiae subcylindrical, the anterior ones sometimes feebly arcuate; tarsi depressed, rather broad, the first joint of the anterior pair not longer than the second joint. Body very variable. This is a very large genus and includes nearly 500 described species, which are distributed throughout the warmer parts of the world, with the exception of Australia and Oceania. Only a few species are found in Malaysia, where they are replaced by the genus Chrysodema. Fight species have been found in the West Indies, two of which are described in the present paper. Kerremans has divides the genus into four subgenera, but all of the West Indian species, except fulgida Olivier, belong to the subgenus Lampetis Dejean, which is separated from the other subgenera by the pros- terum not produced at the middle, but with the anterior margin truncate, lobed or feebly sinuate; epistoma short, not separated on the front by a transverse carina, and not declivous in front, nor con- tracted on the sides. A large number of genera have been placed as synonyms of this genus by Kerremans, but since their distribution do not apply to the fauna covered by the present paper, the citations are omitted.

In the collection of Gigot D’Orcy. 50 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 Originally described by Olivier (1790) from Guadeloupe, and is recorded from the same locality by Fleutiaux and Sallé (1896). Castelnau and Gory (1837), and also Kerremans (1910) record it from Cayenne, French Guiana, without refering to the type locality, which they have probably overlooked. No specimens have been seen which would apply to the description given for this species. Kerre- mans** records a specimen of Psiloptera variolosa Fabricius from Guadeloupe in the Paris Museum, which probably is this species.

Abdomen be- neath coarsely and irregularly punctate, becoming feebly longitudi- nally rugose at the sides, and rather densely clothed with short re- cumbent cinereous hairs; first segment feebly longitudinally sulcate at middle; last segment at apex, broadly rounded in the female, substruncate in the male. Prosternum strongly convex, not sulcate along the anterior margin, which is truncate, the surface rather densely and coarsely punctate and sparsely clothed with incon- spicuous hairs; prosternal process broad, flat, and sparsely and very coarsely punctured at middle, with a deep marginal groove, which is sparsely, coarsely punctate, and sparsely clothed with a row of erect inconspicuous hairs, sides parallel to behind the anterior coxal cavities, then abruptly attenuate, and deeply arcuately emarginate to the apex, which is subtruncate, or feebly rounded. Length, 22-28 mm.; width, 8.5-10.5 mm. Castelnau and Gory (1837) described this species from St. Vin- cent, and it seems to be rare in collections. Material has been ex- amined from the following localities. Coll. British Mus.: One speci- men, Grand Ance, south end, Grenada; one specimen, Mustique Island, Grenadines (H. H.

Length, 16-27 mm.; width, 6-10 mm. ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 53 This species was described by Dalman (1832) from Cuba. Chev- rolat (1867) records it from all parts of Cuba, in the collections of Gundlach, Poey, and Chevrolat. Gundlach (1891) records it as being distributed throughout the entire island of Cuba, and reports it taken a number of times on the stems of the “Icaco.” Kerremans (1910) records it from Cuba and Jamaica, but the latter locality applies to the variety described in the present paper. Material has been examined from the following localities: Coll. Amer. Mus. Nat. Hist.: Four specimens, labeled Santiago de Cuba, without additional data; one specimen, Santiago, Cuba, September 6, 1903 (Wirt Robinson); one specimen, Cienfuegos, Cuba (Dr. Eugenio Cuesta); and another one from Aguadores, on the coast near Santiago de Cuba, August 25, 1908 (Chas. T. Ramsden). Coll. Acad. Nat. Sci. Phila.: Two specimens, Cuba (Poey Coll. No. 12). Coll. British Museum: One specimen, Cuba (Coll. Chevrolat) ; and another one labeled simply Cuba. Coll.

Mus.: Six specimens from Cayamas, Cuba, collected be- tween December and May by E. A. Schwarz. There are also two specimens of this species labeled No. 2 in the Gundlach Museum in Habana, which have not been examined. This seems to be the most common species of this genus found in the West Indies, and can be separated from all the other species from that region, except the variety jamaicensis, by the elytra hav- ing a distinct longitudinal groove along the lateral margins, which is usually filled with a dense yellowish pulverulence. From the variety it can be separated by the color. PSILOPTERA (LAMPETIS) TORQUATA, var. JAMAICENSIS, new variety Similar in shape and structure to torquata, but differs from it in the color. Elevations above brownish-black, with a feeble cupre- ous tinge when viewed in certain lights, and the depressed areas olive-green or aeneous; beneath olivaceous, with a strong cupreous reflection. Length, 18-30 mm.; width, 6.5-12 mm. Type locality—Pallisadoes, Kingston, Jamaica. Type, allotype, and paratypes Carnegie Museum. Paratypes.—Cat. No. 26805, U.S.N.M. One paratype in British Museum. This variety described from 9 specimens, four males and four females received the Carnegie Museum, which were collected at the type locality October 1898, and one male from the British Museum labeled Jamaica, without a definite locality. 54 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 After examining a large series of specimens from both Cuba and Jamaica, it seems advisable to separate the form found in Jamaica from the typical torquata, and give it a new varietal name.

Scutellum transverse, more or less depressed at middle, and the surface densely granulose. Elytra wider than pronotum at base, strongly arcuately expanded behind the humeral angles, nearly parallel to near the apical third, then arcuately at- tenuate to the tips, which are truncate, and very feebly sinuate or emarginate; lateral] margins very coarsely crenulate on the basal expanded parts, and entire posteriorly; humeral angles broadly rounded; surfaces striato-punctate, the striae feebly impressed. and the punctures coarse, shallow and remotely placed, intervals feebly convex and finely granulose, the striae and intervals interrupted by numerous transverse irregular depressions, which are coarsely and densely punctate, rather densely clothed with short inconspicuous hairs, and usually covered with a pulverulence similar to that on the pronotum.

Prosternum not transversely concave along anterior margin, which is truncate or very feebly emarginate at middle; surface sparsely and very coarsely punctate; prosternal process broad, feebly convex, smooth at middle, with a deep marginal groove, which is rather densely punctate and sparsely clothed with a row of long erect cine- reous hairs, sides parallel to behind the anterior coxal cavities, then strongly attenuate, and arcuately emarginate to the apex, which is very broadly rounded. Length, 17-27 mm.; width, 6-11mm. Originally described by Olivier (1790) from a specimen which he believed was found at Cayenne, Guiana, and this locality was quoted by all of the older writers. The same species was also de- scribed from Haiti by Castelnau and Gory (1837) under the name amethystipes. Mannerheim (1837) described a species from Santo Domingo under the name wurtembergi and recorded it from Cephalantho salicifolia. Kerremans has placed this species as a synonym of torquata Dalman, but it is certainly not that species, but should be placed as a synonym of awrifer Olivier. Jacquelin 56 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 65 Duval (1857) records it from Santo Domingo and Cuba. Chevrolat (1867) also records it from Santo Domingo, in the collection of Chevrolat, and from Cuba in the collection of Dejean. Gundlach (1891) states that it is very doubtful from Cuba, but that it is found in Santo Domingo. Kerremans (1910) records it from Port au Prince, Haiti, in the Paris Museum, Brussels Museum, and the collections of Théry and Kerremans. This species is without any doubt confined to Santo Domingo, and the records given by Chey- rolat and Jacquelin Duval of a specimen in the Dejean collection from Cuba, probably is based on aulica, which is a synonym of torquata, as Dejean never recorded a specimen in -his collection under the name of awrifer. Specimens have been examined from the following localities. Coll.

Kerremans (1908) records it as dis- tributed throughout all the Antilles, and Fleutiaux and Sallé (1890) record gigantea Linnaeus from Guadeloupe, which probably refers to this variety. The following West Indian material has been examined: Coll. British Mus.: Two specimens, one labeled Guadeloupe (Tarnier) and the other Cuba (Heyne).

The following is a copy of the very short original description given by Linnaeus: B. elytris serratis sulcatis, tibiis angulatis, abdomine glabro. Habitat in Indiis. Saunders (1871) lists the species from Brazil, Leng and Mutch- ler (1917) from the Antilles, and Kerremans (1908) records it from South America and the Antilles, saying that he has not seen the species, and also that it is the only Linnean species which he has not examined. Hope (1840) says that it is probably a Pelecopcephalus of Serville, and that Gmelin mentions the locality South America, as well as India, but he regards it as belonging to the former. Linnaeus (1758) in the original description gives “ Indiis” as the locality, which may refer to either the East or West Indies, and not to India as stated by Gmelin. The species is practically unknown, is unrecognizable from the short description, and the locality is also very questionable. It probably is a South American species and does not belong to the West Indian fauna, but is included in the present paper, since it has been recorded in the literature from the Antilles. 66 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 Genus CHRYSESTHES Solier Chrysesthes Souter, Ann.

Antennae short; first joint elongate, and feebly clavate; second very short, obconical; third slender, elongate and feebly triangular; fourth about equal in length to the third, but broader at the apex; the following joints feebly triangular and becoming gradually shorter toward the last joint, and armed with the poriferous pores on both sides of the joints, and with a small fovea on the under side near the anterior apical angle. Eyes rather large, elliptical, feebly convex, and slightly closer to each other on the vertex than at the front. Pronotum wider than long, moderately convex, and the disk with three longitudinal im- pressions; base feebly sinuate. Scutellum small and rounded. Ely- tra moderately convex, nearly truncate at base, attenuate poster- iorly, sides with a single tooth near apex. Sternal cavity formed by the mesosternum and metasternum; mesosternum divided, the lateral branches rather long and oblique; metasternum truncate in front, with a deep arcuate groove on the disk. Prosternum feebly convex, the anterior margin arcuately emarginate and strongly elevated; prosternal process wide, feebly convex, and not sulcate at middle. Posterior coxae strongly dilated internally; anterior mar- gin strongly sinuate; posterior margin oblique, usually with a large obtuse tooth near the middle, but sometimes obsolete. Legs slender, anterior and middle femora slightly swollen at middle, the posterior pair subcylindrical and feebly flattened on both sides; tibiae slender and cylindrical; tarsi depressed, the first joint of the posterior pair nearly as long as the following two joints united. First abdominal segment nearly as long as the following three seg- ments united, and more or less concave at the middle. Body elongate, attenuate in front, and more acuminate posteriorly. This name was first used by Saunders (1871) for two species, mannerheimi Mannerheim, and chalcoptera Jacquelin Duval without giving any description, but Thomson (1878) gives a description of the genus under the same name, in which he includes both of the species listed by Saunders. At present the genus includes three species, two of which have been described from Haiti, and the other from Cuba. 70 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 The genus is very closely allied to Halecia, and Kerremans sepa- rates it from that genus by the posterior margin of the hind coxae strongly toothed at the middle, but this character is variable, and in chalcoptera is nearly obsolete. All the species of Hilarotes can be separated from the species of Halecia found in the West Indies, by the lateral margin of the elytra armed with a single strong tooth near the apex.

Length, 19 mm.: width, 7.5 mm. This species was described by Castelnau and Gory (1838) from a specimen in the Buquet Collection from Santo Domingo, and Non- fried (1891) described the same species from Haiti under the name Psiloptera aureomicans. Kerremans (1909) records it from Haiti in the Paris Museum and also in the collections of Théry and Ker- remans. It semes to be rare in collections and confined to the island of Haiti. Through the kindness of the British Museum I have been able to examine two specimens, one labeled Port-au- Prince, Haiti, and the other simply Haiti (Obenthur), both of these specimens are also labeled aureomicans Nonfried, and later de- termined by Kerremans as nitidicollis Castelnau and Gory. (One of these specimens has been donated to the U. S. Nat. Mus.) Kerremans * has placed chalcoptera Jacquelin Duval as a synonym of this species, but it is quite distinct from nitidicollis and is con- fined to the island of Cuba. 16 Mon.

The following is a translation of Mannerheim’s original descrip- tron: Greenish-bronzy, antennae black; femora violaceous at tip; head rugosely punctate; thorax dilated at base; above uneven, deeply canaliculate and rugosely punctate; elytra striate, uneven, the inter- stice punctate, and the alternate ones feebly elevated. Var. b. Violaceous-aeneous, marked with greenish-bronzy; elytra greenish-bronzy lineate; legs greenish-bronzy, the femora at apex and tarsi violaceous. Island St. Domingo, collected by Mr. Jaeger. Length, 8 lines; width, 3 lines. Head strongly rugosely punctate, front deplanate. Antennae black, and slightly shorter than the head and thorax. Thorax scarcely longer than the width in front, and at the base almost two times wider, and here as at the apex bisinuate; sides feebly constricted behind the middle, and thence dilated, posterior angles acute and rather prominent; above deeply rugosely punctate, very uneven, and throughout the entire length deeply and broadly canaliculate. Scu- tellum small, orbicular, and smooth. Elytra at base much broader than thorax, nearly four times as long as the thorax, and gradually attenuate posteriorly ; apex subemarginate, and dentate on the inside; sides margined, the margin ending in an acute tooth a little before the apex; above very uneven, at the humeri deeply foveate, striate; interstice irregularly punctate, the alternate ones feebly elevated. Body beneath and legs deeply punctate, the-punctures here and there rugose. This name was first used by Dejean (1833) for a specimen in his collection from Santo Domingo under the name inaequalis Man- nerheim, (which was*a manuscript name) without giving a descrip- tion of the species. Mannerheim (1837) described the species, using the same name as listed in the Dejean Catalogue. The species is very rare in collection, as Gory made his figure from the specimen in the Dejean Collection, and the species was unknown to Kerre- mans. No specimens have been seen which agree with the descrip- tion, and the species is included in the key from the characters given in the original description.

Head nearly flat, and without any depressions on the front, but with a narrow longitudinal groove on the vertex and occiput; surface not rugose, but coarsely, deeply and rather sparsely punctate, the punctures well separated and irregularly placed; intervals smooth; epistoma broadly truncate in front; antennae aeneo-brunneus, the basal joints green, with the first joint testaceous at base. Pronotum about one and one-half times as wide as long, distinctly narrower in front than behind, widest at base; sides feebly obliquely expanded from apex to basal fourth, then abruptly and obliquely expanded to the posterior angles, which are rather acute; anterior margin ar- cuately emarginate, with an obtusely angulated lobe at the middle; base transversely truncate to middle of elytron, and with a broadly rounded median lobe, which is arcuately emarginate in front of scutellum; lateral margins rounded and smooth anteriorly, with a short smooth carina at the base; disk with a broad longitudinal sul- cus, which is more deeply impressed near the scutellum, a broad obsolete one on each side, extending from the base to near the middle, and a deep narrow one along the anterior margin, broadly inter- rupted at the middle, these depressions causing a broadly rounded gibbosity near the posterior angles; surface coarsely, sparsely and irregularly punctate, and very sparsely clothed with short incon- spicuous hairs, the intervals irregular in size and finely and obsoletely punctured. Scutellum rounded or transversely oblong, slightly more acutely rounded posteriorly, with the surface nearly smooth. Elytra distinctly wider than pronotum at base, broadly arcuately expanded behind the humeral angles, nearly parallel to behind the middle, then strongly arcuately attenuate to the tips, which are obtusely rounded and bidentate, the lateral margins with a large tooth near the apex; disk with a broad irregular basal depression; surface striato-punc- tate, the striae feebly impressed, regular on the disk, but becoming more irregular and somewhat confused at the sides, the punctures in the striae fine, remotely and ratherly regularly spaced, some of the intervals more strongly convex, especially toward the apex, and sparsely, irregularly punctate, from each puncture arises a short in- 74 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 conspicuous hair, which is more erect than those in the striate.

Posterior coxae with the median tooth on posterior margin only feebly developed. Length, 15-17 mm.; width 5.5-6.5 mm. This species was described by Jacquelin Duval (1857) from Cuba, and its distribution is probably confined to that island. Chevrolat (1867) records it from Cuba, in the collections of Gundlach and Poey. Gundlach (1891) reports collecting it in the western part of Cuba. Through the kindness of the Academy of Natural Sciences, Phila- delphia, I have been able to examine two specimens from their col- lection labeled Cuba (Poey Coll. No. 14), from which the above de- scription was made, and which are probably the specimens referred to by Chevrolat. The specimens are probably both females. (One of these specimens has been donated to the U. S. Nat. Mus.) There is also a single example of this species labeled No. 308 in the Gund- lach Museum in Habana, and another one in the British Museum, which have not been examined. Kerremans has placed this as a synonym of nitidicollis Castelnau and Gory, but it is a distinct species. The elytra are aeneo-cupreous and more finely punctured, pronotum distinctly narrower in front than behind, and widest at base, the surface more finely punctured and the longitudinal depressions on each side of the middle more obsolete, prosternum more densely punctured, the anterior margin declivous, and not elevated, and the underside of the body green, with a violaceous tinge.

This genus is distributed throughout the Nearctic and Palaearctic Regions, and includes about 20 described species, of which only two have been recorded from the West Indies. One of these was origi- nally described from Guadeloupe, and the other was introduced into Cuba, probably in pine timber from the United States. The species are closely allied, but the following table, which is taken from Ker- remans Monograph, may be of some assistance in separating the two species.

Head broadly but not deeply depressed, the depression extending to the margin of the eyes, and from the epistoma to the vertex, and with an obsolete narrow longitudinal groove on the occiput and vertex ; surface coarsely and rather sparsely punctate, the punctures shallow and irregularly placed; intervals smooth; epistoma broadly, arcuately emarginate in front, with the outer angles of the emargina- tion forming an obtuse tooth. Pronotum about one and one-half times as wide as long, base and apex about equal in width; sides feebly arcuately attenuate to the basal sixth, where they are strongly sinuate, then obliquely expanded to the posterior angles, which are somewhat projecting and rather acute; anterior margin broadly arcuately emarginate, with the median lobe rather distinct and subangulate; base feebly bisinuate, with a broadly rounded median lobe; lateral margins rounded and only obsoletely marked poste- riorly; disk with a broad shallow longitudinal sulcus, which is in- terrupted at the middle, a transverse depression on each side along anterior margin, and a broad obsolete one on each side about midway between the median sulcus and lateral margin; surface sparsely and rather deeply punctate, the punctures irregular in size and arrange- ment, and becoming coarser at the sides; intervals smooth.

Female.—Similar to the male, but with the last abdominal segment obtusely rounded at the apex. Length, 12-15 mm.; width 3.5-5 mm. This name was first used by Dejean (1823) for a species from North America, which he placed in his genus Zeptia, but without describing either the genus or species. Gory (1840) described the species under the same name from the specimen in the Dejean col- lection, and placed it in the old genus Buprestis. It has been recorded by Fleutiaux and Sallé (1890) from Guadeloupe, as having been collected by Delauney during September at Camp Jacobs, and also by Vitrac at Trois Riviéres and Petit Bourg on a species of Melasto- maceae. Specimens which I have determined as this species have been ex- amined from the following localities. Coll. U. S. Nat. Mus.: Three specimens, Dominica, June and July, collected by H. W. Foote of the Yale Expedition of 1913; and one specimen from Gaudeloupe (L. Defau). Coll. Amer. Mus. Nat. Hist.: One specimen, Gourbeyre, (juadeloupe. Coll. British Mus.: One specimen, labeled Dominica, G. A. Ramage, 97-67, May 12, 1888. The elytral depressions are slightly more cupreous in the specimens from Guadeloupe, but there is considerable variation even in these specimens. It is just possible that these specimens represent the species described by Kerremans as pyropus from that island, but if so, I can not see any reason for separating the two species.

The following is a translation of Kerremans’ original description: Elongate, at apex attenuate, metallic golden-green, with a cyaneous tinge, the depressions on the head, pronotum and elytra are dark purpureo-violaceous; head granulose, the front excavated; pronotum trapezoidal, uneven, depressed on both sides, and the middle longi- tudinally sulecate; scutellum transverse; elytra punctate-striate, trun- cate and dilated at humeri, the apex attenuate and strongly muricate; each elytron with three impressions, first an elongate one on disk, the . a ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 83 second transverse, and placed behind the middle, and the third small and subapical.

Insectorum, fase. 12, pt. 3, 1908, pp. 193-195. Head vertical and much wider in front than on vertex; front flat- tened and narrowed by the insertion of the antennae; epistoma short and wide, and more or less emarginate or truncate in front; antennal cavities large, round, and situated at a considerable distance from the eyes. Antennae moderately long, variable, and dentate from the fourth joint, the serrate joints usually armed with poriferous foveae on the lower anterior margin of the joints (some of the species also have obsolete foveae on the upper side). Eyes very large, ellipti- cal, inner margin very oblique and much closer to each other on the vertex than on the front. Pronotum much wider than long, and not closely applied to the elytra at the posterior angles; anterior margin arcuately emarginate; sides sinuate; base with a distinct median lobe. Scutellum small and triangular. Elytra variable, shagreened or finely punctured, with or without costae, rarely with the sides serrate near apex, lobed at base, and strongly attenuate posteriorly. Sternal cavity formed by the mesosternum and meta- sternum; mesosternum divided, the lateral branches elongate and somewhat triangular; metasternum feebly emarginate or truncate in front. Prosternum feebly convex in front, with the anterior margin more or less declivous; prosternal process flat, strongly con- stricted by the coxal cavities, behind which it is abruptly and arcuately expanded on each side into a sharp tooth, and with a large acute tooth at the apex, which fits into the sternal cavity. Posterior coxae strongly dilated internally; anterior margin nearly straight ; posterior margin oblique. Legs rather robust; anterior and middle femora more or less swollen, the former nearly always dentate on the inner margin; tibiae normal, the anterior pair frequently arcuate in the males; tarsi rather short, the third joint deeply emarginate and divided into two long divergent spines, which extend beyond the fourth joint; tarsal claws simple or feebly expanded at base. Body oblong, rather broad, and more acuminate behind than in front. The name Actenodes was first used by Dejean (1833) in the sec- ond edition of his Catalogue des Coléoptéres, and in which he in- cluded bellula Mannerheim from Santo Domingo, nobilis Fabricius from Cayenne, and eight species of which no descriptions had been 84 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 65 published. In his third edition of the same work (1836), he gives in addition to the ones mentioned previously, viridifasciata, calca- rata, and chalybeitarsis, all from Mexico and credited to Chevrolat, of which viridifasciata is only a manuscript name, and which was later described by Castelnau and Gory as regularis. Lacordaire (1857) published a description of the genus, and in which he placed a number of species, some of which were previously included in this genus by Dejean. Actenodes is a rather large genus and has a wide distribution, the species being distributed throughout North, South, and Central America, Mexico, West Indies, and Africa. It is closely allied to Chrysobothris and Colobogaster, but can be easily distinguished from either of these two genera by the third joint of the tarsi having two long spines, which extend beyond the fourth joint.

The following is a translation of the original description: Dark aeneous; thorax with three not very deep foveae; elytra cupreous, and marbled violaceous. Length, 9 lines; width, 314 lines. Habitat Martinique. Cupreous, with a feebly darker tinge. Head granulose, with a deep longitudinal groove at the middle, and two elevations between the eyes. Thorax transverse, with an impression at middle behind, and also one on each side, surface covered with small transverse rugae. Elytra granulose, with longitudinal costae, and ornated with an irregular blackish-violet spot at the base, and three irregular oblique “sinuate fasciae of the same color, the posterior one situated at the apex. Body beneath and legs punctate and of a beautiful cupreous color. ‘Tarsi violaceous. This is certainly closely allied to fudminata Schonherr, but ac- cording to the description given by Castelnau and Gory it is a larger ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 85 species, and the elytral markings are cupreous, while in fulminata they are aeneous and differently arranged. In figuring marmorata the pronotum is shown as being transversely impressed along base, while in the description they say that the pronotum has an impres- sion at the middle behind and another one on each side. Since their descriptions are very deficient, these three impressions may be con- nected transversely by a shallow groove, similar to some of the speci- mens of auronotata, in which case it would be transversely impressed as shown in the figure. Since Castelnau and Gory had both of the species before them when they described this species, I shall consider them as two distinct species. No specimens have been seen by the writer which would apply to the above description. ACTENODES FULMINATA (Schénherr) Buprestis fulminata ScHONHERR, Syn.

Form broadly elongate, moderately convex, attenuate in front, more acuminate posteriorly; and narrower behind than in front, gla- brous and shining; head and pronotum aeneous, with a strong oliva- ceous and purpureous tinge; scutellum green; elytra nigro-viola- ceous, with irregular transverse aeneous markings; beneath oliva- ceous-green, with the tarsi and last abdominal segment cyaneous. Head feebly convex, front nearly flat, triangular, with a longi- tudinal groove extending from near the epistoma to vertex, the groove feebly impressed on the front, but becoming very deep on the vertex between the two nodules, which are broad, but not strongly elevated; surface densely, irregularly and deeply punc- tate, becoming strongly transversely scabrous on the anterior part; intervals nearly smooth, becoming obsoletely granulose on the occi- put; epistoma feebly, broadly emarginate in front, with an obso- lete median tooth; eyes large, very oblique and about two times as widely separated on the occiput as in auronotata. Pronotum strongly transverse, and moderately convex, two times as wide as long, apex and base about equal in width, widest at apical third; sides broadly rounded at apical third, then arcuately attenuate to the posterior angles, which are nearly rectangular; anterior margin arcuately emarginate, with an obsolete median lobe; base bisinuate, with a broad, feebly rounded median lobe; surface with a very broad longi- 86 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 tudinal median depression, deeper behind than in front, and on each side of which is a large, moderately deep, round depression, sparsely, deeply and rather regularly punctate on the disk, becom- ing coarsely, irregularly rugose toward the sides, the rugae long, strongly elevated, and widely separated; intervals finely and densely granulose. Scutellum very small, triangular, the sides about equal in length. Elytra distinctly wider than pronotum ‘at base; sides broadly rounded at humeral angles, nearly parallel to behind middle, then obliquely attenuate to the tips, which are rather acute; lateral margins very coarsely serrate to near middle; each elytron strongly angularly lobed at base, with a feeble transverse basal impression, and four more or less distinct sinnuate longitudinal costae, none of which extend to the apex; surface densely, deeply and irregularly punctate, the punctures becoming confluent toward the sides; inter- vals densely and rather coarsely granulose; each elytron ornated with aeneous markings, which are very narrowly margined with cyaneous and arranged as follows: An elongate circle enclosing a dark area at base and extending backward forming the letter C, with the opening toward the suture; at basal third a broad trans- verse fascia, forming posteriorly the letter W between the first and second costae, and then extending transversely to the suture, and forward along: the suture to the base; at the middle there is a very irregular zigzag fascia extending from the lateral margin and form- ing the letter M between the first and second costa, then obliquely backward to the suture ‘at apical third, and following the suture te apex, where it is sometimes connected to a narrow band along the lateral margin, which extends forward to the apical third; there is also an oblong spot behind the humeral angle. Abdomen beneath moderately convex, sparsely but not very deeply punctiate; intervals smooth and shining; last segment more densely punctured posteriorly, with the apex broadly sinuate and armed on each side with a tooth. Prosternum feebly convex, broadly truncate and declivous in front; surface sparsely and rather coarsely punctate, becoming ir- regularly striolate toward the sides; prosternal process feebly con- vex, strongly expanded behind the coxal cavities, the sides very long and acute, and extending between the anterior and middle coxae, the median tooth long and acute at apex. Posterior tibiae with a dense line of very long fine hairs on the inner margin. ~ Length, 15 mm.; width, 6 mm. This species was described by Schonherr from Brazil, and the above description was made from a specimen donated to the United states National Museum by the British Museum, which was col- lected at Jatahy, Brazil, and determined by Kerremans as fulminata Schonherr. Actenodes cyanura was described by Chevrolat from Cayenne, and has been placed as a synonym of fulminata by Kerre- aS ART. 9 * WEST INDIAN BUPRESTIDAE—FISHER 87 mans. I have examined another specimen received from the British Museum from Cayenne, and labeled “ signata Beaud.-Lafarge, cya- nura Chevr.” which agrees very well with Chevrolat’s description of eyanura, and which only differs from the specimen of fulminata from Brazil in a few minor details; being smaller (12.5 mm. long; and 5 mm. wide), head not quite as densly rugose, median depression on pronotum more obsolete anteriorly, and the elytra more sparsely and finely punctate, otherwise they are the same, which verifies Ker- remans conclusions as to the synonymy. So far, this species has only been recorded in the literature as oc- curing in the West Indies, by Leng and Mutchler in their Prelimi- nary List of the Coleoptera of the West Indies.“ This record was probably copied from Linell’s card catalogue of the West Indian Coleoptera, in which he had recorded the original description of cyanura Chevrolat, and erroneously cites the locality as Martinique instead of Cayenne. The species probably does not occur in the West Indies, its distribution being restricted to South America, but the above description is included, so that in case its distribution should extend into the Antilles, it can be easily identified.

Form elongate, and moderately convex, attenuate in front, more acuminate posteriorly, and narrower behind than in front, subo- paque and glabrous; dark aeneous, with a feeble olivaceous or pur- pureous tinge; scutellum aeneo-viridis; each elytron ornated with four green spots (the two discal ones strongly embossed), which are narrowly marginal with aureo-cupreous, and sometimes the margin behind scutellum narrowly cupreous; beneath aeneous, with an oliva- ceous tinge, and more shining and purpureous than above; tarsi cyaneous. Length, 10-14 mm.; width, 4-5.5 mm. This species is very closely allied to auronotata Castelnau and Gory, but differs from it as follows: Form more slender, elytra more acuminate posteriorly, surface more finely punctured, and the spots smaller, round, and the four discal ones distinctly embossed, and of a clearer green color, narrowly margined aureo-cupreous; sides of prosternum more coarsely punctate, and the punctures more con- fluent. 17 Bull.

Actenodes bellula, var. sobrina as used by Dejean is a manuscript name, but Mannerheim (1837) under the name of bellula gives a description of the A. bellula, var. sobrina Mannerheim listed by Dejean in his Catalogue from the island of Santo Domingo, and in which he writes, “ Not possessing the real Actenodes bellula Dejean, I have been obliged to describe the variety.” Since no description had been published of bellula, this name must be applied to the species described by Mannerheim from Santo Domingo, and sobrina Mannerheim will have to be placed as a synonym of that species. The specimen in the Dejean Collection under dellula Dejean from Cuba, will be the true auronotata Castelnau and Gory. Chevrolat (1867) records this species from Santo Domingo in the collection of (Dejean) Mnizech, and considers it distinct from auronotata.

Chevrolat (1867) says that it found over the en- tire island and in the collections of Gundlach, Poey, and Chevrolat. I have examined specimens from the following localities. Coll. Amer. Mus. Nat.

Hol- land, and which were collected by F-. Klages. There is aiso a speci- men loaned by the British Museum and labeled Jamaica 78-22, which I have placed with this variety. It differs from the type only in coloration, being more brownish-green, and not so reddish-cupre- ous as in the type. This species is very closely allied to awronotata Castelnau and Gory, but at least should be separated from that species as a good variety. It differs from it in the coloration, which is of a reddish- cupreous color, more shining, and not quite as convex, the elytra not quite as densely punctate and the punctures more widely separated, the base, suture, and posterior half of elytra margined with green, elytral spots bright green, the two in front of middle larger and nearly confluent, and with a short oblique fascia at apical third.

Head vertical, much wider in front than on vertex; front even or uneven, narrowed by the insertion of the antennae, and frequently separated from the vertex by a sharp transverse carina; epistoma broad, more or less sinuate or emarginate in front, and constricted posteriorly by the antennal cavities, which are small, rounded, and situated at a considerable distance from the eyes. Antennae moder- ately long; first joint elongate, clavate and feebly arcuate; second very short and globular; third elongate and more or less clavate; the first three joints as long as the following joints united; following joints triangular, usually transverse, and armed with a poriferous fovea situated on the interior margin of the joints. Eyes very large, elongate, inner margins very oblique, and much nearer to each other on vertex than at the front. Pronotum much wider than long, and variable in shape; base strongly bisinuate, frequently lobed at the 92 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 middle, the lobe sometimes strongly produced and truncate. Scu- tellum very small and triangular. Elytra variable, lobed at base, strongly attenuate posteriorly, with the sides near apex frequently serrate. Sternal cavity formed by the mesosterum and metaster- num; mesosternum divided, the lateral branches variable in shape; metasternum truncate in front, with a very feeble emargination at the middle. Prosternum flat or convex; anterior margin variable; prosternal process constricted by the coxal cavities, behind which it is strongly expanded, with a large acute tooth at the middle, which fits into the sternal cavity. Posterior coxae strongly dilated inter- nally; anterior margin subsinuate; posterior margin oblique. Legs rather robust; femora swollen at middle, and the anterior pair more robust, sharp on the inner margin and armed with a large obtuse tooth (very rarely the tooth is absent); anterior and middle tibiae more or less arcuate; posterior pair straight; tarsi compressed, first joint of posterior pair rather long, third joint feebly emarginate, and not armed with two long spines, the fourth very short; tarsal claws simple. Body oblong, rather broad, rarely elongate, and more attenuate behind than in front. The species of this genus are very numerous, and are found in nearly all parts of the world. Some of the species are of great economic importance, one of which occurs throughout the West Indies has become very injurious to the Australian Pine (Casuarina equisetifolia Forster) in the southern part of Florida, where this plant has been introduced for ornamental purposes. Of the other species found in this region, practically nothing is known of their life histories. This genus is closely allied to Actenodes, but can be easily sepa- rated from that genus by the absence of the two long spines on the third joint of the posterior tarsi. KHY TO THE SPHCIES 1.

Prosternum broadly rounded in front, and without a median lobe; surface transversely depressed along anterior margin, sparsely, finely punctate, transversely rugose, and sparsely clothed with long cinereous hairs; prosternal process flat, strongly expanded behind coxal cavities, and the apex with a long triangular tooth. Femora robust, anterior pair with a large obtuse tooth on the outer 98 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 65 edge, situated closer to the apex than base, and feebly dentate on the exterior margin. Anterior tibiae suddenly reflexed at middle and not dilated at apex; middle pair strongly arcuate; posterior pair straight. Female—Differs from the male in having the front of head less pubescent and the chevron on vertex more distinct, anterior and middle tibiae nearly straight, the last ventrai segment of abdomen with a broad median carina at base, a depression on each side, and the apex with two shallow semi-circular emarginations, the median tooth short and the lateral ones long and acute. Length, 12-16 mm.; width, 5-7 mm. There has been considerable confusion in regard to the identifica- tion of this species. This insect is a common and destructive enemy of the red mangrove (2hizophora mangle Linnaeus) but did not become of any great economic importance until about the year 1916, when it attacked the Australian Pine (Casuarina equisetifolia Fors- ter) planted in southern Florida for shade and ornamental purposes. As this insect is rather widely distributed throughout the West In- dies, and the Australian pine is also being planted in these islands, it may become an economic problem in that region. The specimens do not seem to vary except in the coloration of the elytral foveae, in some specimens the foveae are unicolorous with the elytra, while in others they are distinctly purplish. It has a rather wide distribu- tion, having been taken in nearly all of the Antilles and the southern part of Florida. So far, there are no authentic records of it having been collected in Cuba, and this is rather strange, since its natural food plant is found on this island. The only other species with which it could be confused is twmida Chevrolat, described from Cuba, but is easily separated from that species by the anterior femora having a large obtuse tooth on the outer margin. Fabricius (1787) described the species from ‘“ Tranquebarica ” under the name @mpressa, which he had previously used (1775) for another species from “ Indiis.” Gmelin (1788) proposed the new name tranguebarica for this species. Olivier (1790) proposed a new name excavata for the same species, and this name was used by Fabricius in all his later works. Fabricius and Olivier, either did not know of Gmelin’s work, or would not recognize his names, as the name tranquebarica was not used by either of these writers in their works. Mannerheim (1837) described the species as fraterna from Porto Rico, and rwgosa from an unknown locality. Castelnau and Gory (1837) described denticulata from Guadeloupe, and gives an excellent figure of the species, which is the species found in Florida, but in their addenda places it as a synonym of fraterna Mannerheim. Gory (1840) described denticollis from Colombia, which is not different from denticulata. Chevrolat (1867) records 4 ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 99 it from Santo Domingo and Guadeloupe, in the collection of the author, and writes that it is common in these two islands and prob- ably will be found in Cuba. Gundlach (1891) records it from the same localities. Fleutiaux and Sallé (1890) record it from Guade- loupe: Camp Jacobs (Delauney); Basse-Terre, “dans les poteaux de la cour du séminaire” (P. Coste) (Vitrac). Snyder (1919) re- cords the habits of this species in Florida and gives methods for combating it. It is also recorded by Gundlach (1894), and Stahl (1882) from Porto Rico.

Pronotum strongly transverse, two and one-half times as wide as long, widest along middle, slightly narrower in front than behind; sides obliquely expanded to apical third, then parallel to basal third, and finally strongly concavely attenuate to the posterior angles, which are rectangular; anterior margin arcuately emarginate, without a median lobe; base broadly arcuately emarginate on each side at the elytral lobes, with a broadly rounded median lobe, which is broadly and feebly emarginate in front of scutellum; disk moderately convex, with a very feeble median depression, and on each side of which is a round deep de- pression in front of elytral lobe, and a deeper transverse one along the anterior margin, there are also two more or less obsolete irregular depressions at the sides; surface coarsely and densely punctate, the punctures irregularly placed, and becoming coarser and confluent at the sides; intervals nearly smooth. Scutellum very long and acum- inate at apex, and the surface obsoletely granulose. Elytra wider than pronotum at base, but almost equal in width to it at the middle; sides broadly rounded at humeral angles, nearly parallel to apical third, then arcuately attenuate to the tips, which are obtusely rounded; lateral margins strongly serrate to the humeral angles; humeri moderately prominent; base with a rather acutely rounded _lebe; disk feebly convex, and each elytron with four costae, the first extending from apex along suture, and elevated to basal third, where it bacomes obsolete, the second feebly elevated, beginning at the pos- terior fovea, extending forward to near the base, and interrupted by the median fovea, the third feebly elevated and extending from the median fovea to near the apex, and narrowly interrupted by the pos- terior fovea, and the fourth rather strongly elevated, extending along the lateral margin behind the posterior fovea, but not quite attaining the apex; surface coarsely and densely punctate, the punctures denser and more confluent in the foveae and toward the sides; intervals smooth.

Prosternum broadly and obsoletely emarginate in front, without a median lobe; surface transversely depressed along anterior margin, sparsely and rather coarsely punctate, transversely rugose anteriorly, and sparsely clothed with long cinereous hairs; prosternal process flat, strongly expanded behind the coxal cavities, and the apex with a long triangular tooth. Anterior and middle femora moderately robust, the former without the usual large tooth; poste- ‘rior pair subcylindrical and not enlarged at middle. Anterior and middle tibiae feebly arcuate and subcylindrical; posterior pair straight. Length, 15 mm.; width, 7.5 mm. The locality given by Chevrolat (1867) in the original description is Cuba, from the central part of the island in the collections of Gundlach and Poey. Gundlach (1891) records it from Cuba with- out giving any additional notes. The above description was made from two female specimens kindly loaned by the Academy Natural Sciences Philadelphia, and labeled Cuba (Poey Coll. No. 986). (One of these specimens has been donated to the U.S. National Museum). There is also a single example of this species labeled No. 839 in the Gundlach Museum in Habana, which has not been available for study. The species is very closely allied to tranguebarica Gmelin and might be easily mistake for that species. It is, however, easily dis- tinguished from that species by the anterior femora not having the usual large tooth on the outer margin, by being broader in propor- tion to its length, sides of pronotum parallel at middle, posterior foveae on the elytra more irregular and extending between the first and fourth costae, and the last ventral segment of the abdomen in the female broadly, but not deeply arcuately emarginate at the apex, while in tranquebarica the female has two semi-circular emargina- tions at the apex. The species seems to be rare in collections, as no specimens have been recorded except the ones mentioned by Chev- rolat in the Gundlach and Poey Collections. It seems to be confined to Cuba, and probably has a different food plant from tranquebarica.

It is closely allied to C. cordicollis described by Castelnau and Gory from South America. Since their description is so short and incomplete, and the specimen before me does not entirely agree with the description given by these authors, I am describing it as new.

Head feebly convex, with the front flat and triangular, and the sides obliquely narrowed to the vertex, where they are feebly arcu- ately expanded; occiput rather wide, with a broad smooth longi- tudinal carina, which is grooved in the middle; front somewhat uneven, but without distinct impressions; vertex without transverse carina; surface coarsely, densely, and irregularly punctate, the punc- tures shallow and confluent, forming a network of irregular polyg- onal areas, the sides of which are smooth and in some places sharply elevated and rugose, rather densely clothed with long, very fine erect hairs, which do not conceal the surface; eyes not very large, narrow, feebly convex, bottom and top about equal in width, but more truncate at the bottom, and separated on the occiput by about the same distance that separates the antennal cavities; epis- toma depressed, broadly triangularly emarginate in front, with the lobe on each side strongly angulate at the middle; antennae rather long, third joint only a little longer than the fourth, and the fol- lowing joints very compact. Pronotum strongly transverse, nearly two times as wide as long, widest at apical third, slightly narrower behind than in front; sides broadly rounded to apical third, then feebly sinuate and obliquely attenuate to the posterior angles, which are rectangular; anterior margin arcuately emarginate, with an obsolete median lobe; base bisinuate, with a very broad median lobe, which is broadly truncate in front of scutellum; surface uneven, the disk moderately convex, with a broad median sulcus, wider in front and limited on either side by a broad elevated smooth space, between which and the margin are two large irregular depressions, one near the anterior margin and the other at base, the latter margined pos- teriorly with an acutely elevated carina, surface also densely and coarsely punctate, the punctures irregularly placed and becoming confluent in the depressions and at sides. Scutellum small, trian- gular, with the sides equal in length, and the surface obsoletely granulose. Elytra distinctly wider than pronotum at base; sides broadly rounded at humeral angles, nearly parallel to apical third, then arcuately attenuate to the tips, which are separately, narrowly rounded; lateral margins feebly serrate to the middle, the teeth very short and more closely placed teward the apex; humeri not very ART. 9 WEST INDIAN BUPRESTIDAE—-FISHER 105 prominent; base broadly rounded, without a distinct lobe; disk rather flat, with a deep basal depression, the first costa along suture distinct on apical half, terminating in front in a vague, smooth space, between this costa and lateral margin are three somewhat transverse, broad smooth spaces of irregular shape, the surface be- tween these is densely, coarsely, and irregularly punctate. Abdomen beneath coarsely but not very closely punctate, the punctures with the posterior margins not well defined, and from the center of each arises a very short inconspicuous hair; intervals nearly smooth; first segment feebly depressed at middle; last segment longitudinally depressed along lateral margins, which are serrate, without a sub- marginal ridge, and with the apex broadly arcuately emarginate. Prosternum truncate in front and without a median lobe; surface coarsely and sparsely punctate, more densely and finely along the anterior margin, and sparsely clothed with long inconspicuous cine- reous hairs; prosternal process nearly flat, strongly expanded behind the coxal cavities, and with a large acute triangular tooth at apex. Femora robust; anterior pair with a large obtuse tooth on the outer edge, closer to the apex than base, and serrate on the exterior margin. Anterior and middle tibiae rather strongly arcuate, flattened on the inner surface and feebly dilated near the apex; posterior pair feebly arcuate and subcylindrical. Female.—Differs from the male in having the head a little more convex, more coarsely punctured, not as pubescent, and with more or less distinct smooth callosities; last abdominal segment with a very small acute emargination at apex; anterior and middle tibiae only feebly arcuate and the posterior pair straight. Length, 10-18 mm.; width, 4-7 mm. This species is easily distinguished from any other species of this genus found in the West Indies by the antennae having joints four to eleven in the greater part distinctly testaceous. The species was described by Germar (1824) from North America, and later under a number of names as given above by various authors. The species is rather common and is found throughout the greater part of the United States, the larvae living in various species of pine. Castelnau and Gory (1837) described rotundicollis from Saint Domingo, and the following is a translation of their original description : Dark aeneous, strongly punctured. Thorax rounded on the sides, with two elevated longitudinal lines, more obscure at the middle. Elytra with irregular, cupreous impressions. of which the two most prominent are situated a little posteriorly. Body and feet cupreous. Length, 6 lines; width, 21/4 lines. A specimen received from the British Museum and labeled Haiti, Saunders 74-18, agrees with the figure and description of rotund:- 106 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 65 collis, although their description is short and does not include the essential characters used at present for separating the species of this genus. In comparing this specimen with specimens of dentipes Germar from the United States, I can not find any differences. These authors * give a figure of a species which they have identi- fied as dentipes Germar, but it is certainly not the species described by Germar from North America, and since Castelnau and Gory apparently did not know the true dentipes, I am inclined to place rotundicollis as a synonym of dentipes Germar. There is a unique specimen under the name votundicollis in the British Museum, but the specimen has not been examined. CHRYSOBOTHRIS BELLA, new species Female—F¥orm rather broad and moderately convex, and shining; above bright bluish-green, and each elytron ornated with reddish- purpureous markings, all of which are obsoletely separated from the suture, and arranged as follows: One covering basal fourth, arcuately rounded posteriorly, and enclosing the green basal depres- sion and humerus; a rather broad transverse fascia just behind the middle, the margins irregular and expanded both near the suture and lateral margin; and a rather narrow crescent-shaped fascia at apical third, feebly oblique, with the concavity toward the apex; beneath green; tarsi cyaneous. Head flat, with the front triangular, and the sides obliquely nar- rowed to apex; occiput narrowly and longitudinally carinate; front broadly and irregularly impressed, the impression causing an obso- lete transverse elevation near vertex, in front of which the impres- sion is deeper, and extending longitudially on each side to the antennal cavities; surface very coarsely and irregularly punctate, and the front sparsely clothed with short inconspicuous hairs; inter- vals finely and densely granulose; eyes large, strongly convex, more arcuately rounded at bottom than on top, and separated on the occiput by about one-half the distance between the antennal cavi- ties; epistoma broadly angularly emarginate in front, and the lobes broadly rounded; antennae short, third joint as long as the follow- ing four joints united. Pronotum strongly transverse, nearly two times as wide as long, widest near apex, slightly narrower behind than in front; sides rather strongly angulated near apex, slightly sinuate at middle, then feebly arcuately rounded to posterior angles, which are rather acute and closely applied to the elytra; anterior margin feebly arcuately emarginate, with an obsolete median lobe; base very strongly angularly emarginate on each side at the elytral lobes, the median lobe broadly rounded, and truncate in front of 19 Mon.

Scutellum small, tri- angular, with the sides equal in length, and the surface obsoletely granulose. Elytra distinctly wider than pronotum at base; sides broadly rounded at humeral angles, nearly parallel to middle, then strongly, arcuately attenuate to the tips, which are produced into an acute tooth at the middle of each elytron; lateral margins strongly serrate to middle, with the teeth rather widely separated: humeri moderately prominent; base strongly angularly lobed; surface without costae, but each elytron with a round deep impression behind the basal lobe, as shallow one near humerus, and witha very feeble im- pression on the median and postmedian green fasciae, sparsely and regularly punctate, the punctures much coarser and denser on the green fasciae, and becoming nearly obsolete at the apex; intervals finely and densely granulose. Abdomen beneath coarsely and very irregularly punctate; first and second segments feebly depressed at middle; last segment with the lateral margins entire, without a serrate submarginal ridge, and the apex with two deep semicircular emarginations, with the median tooth as long as the lateral ones.

Type locality—Mustique Island, Grenadines, W. I. (H. H. Smith). Other localities —Woburn (south end), Grenada, W. I. (H. H. Smith). Type—British Museum. Paratype.—Cat. No. 26808, U.S.N.M. Described from two females received from the British Museum. The type is from Mustique, and the paratype, which only differs from the type in being smaller, is from Woburn, both specimens having been collected by H. H. Smith. The species is very closely allied to pulchra Castelnau and Gory described from South America, without any definite locality. Not having any specimens of pulchra for comparison, and on account of the authors’ descriptions being 108 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 so short and incomplete, I am obliged to describe it as a new species. In their description of pulchra they state that the pronotum has a small longitudinal line at the middle, which is entirely absent in the West Indian specimens. In comparing the specimen with their figure of pulchra, that species seems to be larger and more elongate, the pronotum not angulate near the anterior angles, and with a longitudinal line at middle, the reddish fasciae on elytra are broader in comparison to the green areas, and the tips of the elytra are con- jointly acute, while in de//a each elytron is produced into an acute tooth at middle.

This beautiful species can be easily separated from all the other West Indian species of this genus by the transverse green, violaceous and reddish-cupreous fasciae on pronotum.

W. Watson at Villa Rivas, 20 miles west of Sanchez, Dominican Republic, on June 19, 1915. The col- lecting was done along the north bank of the Ura River to a point one mile east of the town. The locality given by Thomson in the original description is simply “ St. Domingo.” CHRYSOBOTHRIS PARVOFOVEATA, new species Female—Form rather elongate, moderately convex, and sub- opaque; color uniformly dark aeneous; each elytron with four small, round spots, which are deeply impressed, bright green at the bottom, and arranged as follows: One at the basal lobe, a similar one just in front of the middle, and two others near the apical third, of which the exterior one is considerably in advance of the interior one; tarsi cyaneous.

Type locality—Port-au-Prince, Haiti. Type.—Cat. No. 26809, U.S.N.M. Described from a single female collected at the type locality by R. J. Crew and received through the kindness of H. F. Wickham. I have also examined fragments of this species collected by E. G. Smyth at Higueral, Santa Domingo, during February, 1916. The species is closely allied to chlorosticta Thomson, and mega- cephala Castelnau and Gory. From the former it can be separated by the absence of the green markings on humeral angles of elytra, elytral spots smaller, and the epistoma broadly angularly emar- ginate. From megacephala it can be distinguished by the elytral foveae being green, and the posterior ones placed obliquely on each elytron. It is also allied to astuta described by Waterhouse from Mexico, but the pronotum is more strongly angulated anteriorly than in that species, and the elytral foveae are green.

Paratypes.—British Museum and Collection Porto Rico Experi- ment Station. Described from four specimens, two males and two females. The type is from Mayaguez, Porto Rico, without any additional data. The allotype was received from G. N. Wolcott of the Porto Rico Experiment Station, and was collected at Rio Piedras, Porto Rico, July 23, 1916, by E. G. Smyth, on a living twig of jobo (Spondea lutea). There is also a male paratype in the British Museum Collec- tion from Anasco, Porto Rico, collected September, 1913, by E. G. Smyth, and a female paratype in the Porto Rico Experiment Station collection from Rio Piedras, Porto Rico, collected November 25, 1912, by G. Nevarrete. This species was recorded by Gundlach (1894) from Porto Rico as lepida Castelnau and Gory, but it is entirely different from that species. It is allied to Chrysobothris lepida Castelnau and Gory from Cuba, and also to C. chrysoela Illiger from the United States. From both these species it differs by having the epistoma triangularly emarginate, eyes more widely separated on occiput, pronotum more strongly transversely rugose, and the sides less strongly narrowed posteriorly, the last abdominal segment truncate, the transverse green fascia on basal third of elytron connected along the suture and lateral margin to the basal fascia, and the green fascia at apical third slightly turned backward near the suture, while in lepida and chrysoela the green markings usually consist only of spots and are never connected along suture or lateral margin.

This species was described by Fabricius (1798) from the Island of St. Thomas, and the above description was made from a specimen from the type locality, kindly loaned by the British Museum. Herbst ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 125 (1801) described and figured the same species from an unknown locality under the name amabilis. In the U. S. National Museum collection are two specimens from Porto Rico, which I have placed under this species, one collected by G. B. Merrill at Guanica, April 15, 1914, and the other by E. G. Smyth at Santa Rita, during July, 1913. The specimen from Guanica is a male, of the same size as the specimen from the type locality, and only differs from it in a few minor details. The elytral markings, with the exception of the basal ones, are aeneous, and the blackish area is more extended on the disk. The specimen from Santa Rita is a female and is larger than the other specimens, meas- uring 6.25 mm. in length and 2.75 mm. in width, the head is cupreous in front and a little more convex, elytral markings about the same as specimen from Guanica, the under side is uniformly piceous, the first abdominal segment feebly impressed at middle, and the last segment more broadly rounded at the apex. CHRYSOBOTHRIS INSULANA, new species Female—¥orm broadly elongate, moderately convex, and _ sub- opaque; head and pronotum aeneous, with a slight cupreous tinge; scutellum and elytra reddish-cupreous, the latter somewhat pur- pureous on disk, and each elytron ornated with bluish-green spots as follows: A rather broad fascia extending from basal depression transversely along the base and around the humeral angles, an ob- long depressed spot on disk just in front of middle, an irregular transverse fascia at apical third, extending from the lateral margin to the disk but not reaching the suture, a small spot covering the apical area; beneath piceous, with a slight aeneous or greenish tinge, and more shining than above, the elytral epipleura cupreous; tarsi cyaneous. Head feebly convex, with the front triangular and the sides feebly arcuately rounded; occiput narrow, and feebly longitudinally carinate; front not impressed; vertex with an obsolete arcuate trans- verse elevation forming an are with the sides of the front; surface densely and coarsely punctate, the punctures very shallow, without well-defined sides, and from each arises a short recumbent cinereous hair; intervals densely and rather coarsely granulose; eyes large, reniform, strongly convex, more acutely rounded at bottom than on top, and separated on the occiput by about one-third the distance between the antennal cavities; epistoma broadly triangularly emarginate in front, with the lobes broadly rounded; antennae short, the third joint only slightly longer than the following two joints united. Pronotum strongly transverse, one and two third times as wide as long, widest near middle, and the base and apex 126 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 about equal in width; sides regularly arcuately rounded; anterior margin broadly arcuately emarginate, without a median lobe; base broadly arcuately emarginate on each side at elytral lobe, with the median lobe broadly rounded, and truncate in front of scutellum; posterior angles rather obtuse; surface evenly convex, and without impressions, rather densely and regularly punctate, the punctures rather deep, well separated, and becoming somewhat coarser toward the sides; intervals finely and densely granulose. Scutellum very small, triangular, the sides equal in length, and the surface obsoletely granulose. LElytra distinctly wider than pronotum at base; sides broadly rounded at humeral angles, nearly parallel to apical third, where they are slightly wider, then arcuately attenuate to the tips, which are separately broadly rounded; lateral margins rather strongly serrate to near the middle; humeri not very prominent; base broadly arcuately lobed; surface without costae, but each elytron with a round deep basal impression, a shallow one at humerus, a long nar- row one along lateral margin behind humeral angles, a large round deeper impression in the ante-median green area, and a smaller one in the post-median green fascia, densely and regularly punctate, the punctures rather deep and well separated on the disk, but becoming obsolete in the humeral areas; intervals densely and rather coarsely granulose. Abdomen beneath sparsely and coarsely punctate, the punctures shallow, irregularly placed, and from each arises a short inconspicuous cinereous hair; intervals obsoletely granulose; first segment not impressed at middle; last segment with the lateral mar- gins entire, with an obsolete serrate submarginal ridge, and the apex broadly subtruncate. Prosternum with a narrow declivous lobe in front; surface more deeply punctured than the abdomen; prosternal process flat, strongly expanded behind the coxal cavities, and with a triangular tooth at apex; anterior coxal cavities separated by about their own diameter. Femora robust; anterior pair with a large acute tooth on the outer edge, closer to the apex than base, and finely serrate on the exterior margin. Anterior tibiae feebly arcuate, strongly flattened, without any dilatations, the middle and posterior pairs straight and subcylindrical. Length, 6 mm.; width, 3 mm. Type locality —Jamaica. Type.—British Museum. Described from a single female kindly loaned bv the British Museum and labeled Jamaica, without a definite locality. It is closely allied to Chrysobothris lepida Castelnau and Gory, but can be easily distinguished from that species by the pronotum having the sides arcuately rounded and not angulated anteriorly. It is also related to: C. wolcotti Fisher from Porto Rico, but in ART. 9 WEST INDIAN BUPRESTIDAE—FISHER 127 tnsulana the pronotum is arcuately rounded and widest near the middle, the elytral markings are smaller, and the basal and median ones not connected along the suture.

This species is represented also in material examined by us from Sebastian and Paradise Key, Florida, and Knoxville, Tennessee. It was originally described from the West Indies, and has been recorded from Porto Rico, St. Vincent, and Georgia in ad- dition to the above. It is represented in the United States National Museum collection by specimens from Lake Worth, Florida, Texas, and Nicaragua. Genus DECEIA Malloch. Generic characters—Difiers from Minettia in having one sterno- pleural bristle, and two pairs of dorsocentrals, and the intra-alar absent. All tibiae with a preapical dorsal bristle. From Lauwwxani- ella it differs in having the basal antennal segment very much shorter than the second and bare at apex below, and third not four times as long as its greatest width except in incongrua. This genus is divisible into four subgenera, as indicated in the key given below. The genus contains some species which appear to be related to other genera about as closely as they are to the typical species and in the future when material from other faunal regions is carefully studied it may be necessary to recognize as valid genera the groups now accepted as subgenera.

Female.—Similar to fraterna in color. Most closely allied to no- tata Fallen, differing in having the wing markings less distinct, the arista with its longest hairs not noticeably longer than its basal diameter, and the bristles over all not so long and strong. Length, 38 mm. Type and one paratype.—White Mountains, New Hampshire (Mor- rison). Type, Cat. No. 26890. U.S.N.M. SAPROMYZOSOMA NUDIFEMUR Malloch, new species. Male.—Agrees with inaequalis and its allies in color, but in the two specimens before me there is a dark part on third vein beyond outer cross-vein at the point where the dark spot is present in those forms that have distinct spots on wings. There are no hairs between the acrostichal bristles but otherwise the thorax is as in tnaequalis. The tergites of abdomen descend so far that it is impossible to dis- tinguish the fifth sternite, but it has evidently no long processes. Length, 3 mm. Type and one paratype—Kaslo, British Columbia, June 23 and July 7 (R. P. Currie). Type, Cat. No. 26391. U.S.N.M. Genus PERISCELIS Loew. This genus is somewhat doubtfully placed in the Sapromyzidae owing to the lack of mesopleural and preapical tibial bristles as well as the presence of but one orbital bristle. The divergent postvertical bristles and peculiar subcostal vein, which is similar to that of the Trypetidae, distinguish the genus from any other in the three fami- lies dealt with in this paper, but it is more evidently related to Sapromyzidae than to any other family. At present it is recorded only from Illinois, where it has been taken on sap exuding from trees, but its small size and habits prob- ably accounts for its absence from collections. Malloch redescribed this genus under the name Phorticoides with one species, flint? Mal- loch, which may be synonymous with annulata Fallen, a European species.

After the manuscript of this paper was sent to the press a paper by Dr. A. H. Sturtevant appeared in which he records Periscelis an- nulata Fallen from Alabama, South Dakota, and New Mexico.® In the same paper he describes a new genus and species, Sphyro- periscelis wheeleri Sturtevant, from Massachusetts. This genus dif- fers from Periscelis in having the frons much wider, about three times as wide as either eye, the antennal bases separated by about as great a distance as either is from eye, not rather closely approxi- mated, the front of frons flattened, and the outer cross-vein of wing lacking. We have not seen the genus. ® Amer. Mus. Novit., No. 76, p. 1, May 21, 1923.

RESULTS OF THE MULFORD BIOLOGICAL EXPLORATION.— HELMINTHOLOGY. By Epwarp A. CHarrn, Of the United States Department of Agriculture. Among the numerous vertebrates brought to this country by the Mulford Expedition to northern South America were two specimens of the large land tortoise, Zestudo denticulata. ‘These animals died shortly after their introduction into the National Zoological Park and through the kindness of the United States National Museum authorities, the author was permitted to examine the viscera for parasitic worms. Four species of nematodes were found, three of which appear to be new to science. Two of the species fall into the Strongyloidea, one of them representing a new genus; of the re- maining two, one belongs in the Ascaroidea and the other in the Oxyuroidea. Superfamily STRONGYLOIDEA. Family STRONGYLIDAE. SAURICOLA, new genus. Generic diagosis—Strongylidae; Strongylinae, adults about 10 mm. long, head about 140y in diameter. Buccal capsule small, shal- low. Capsule surrounded by two leaf-crowns. Cuticle surround- ing mouth forming a short mouth collar, limited behind by an annular constriction. Six circumoral papillae. Lateral papillae stout, apparently with terminal organ. Submedian dorsal and ven- tral papillae more slender, projecting beyond surface of cuticle, sharply angulate before apex in lateral view. Excretory pore behind the esophagus. Cervical groove and papillae absent. Nerve ring at posterior third of esophagus. Esophagus cylindrical, about twice as long as thick. Bursa of male short, dorsal, and lateral por- tions of membrane not separated, preanal bulla present, enclosing No. 2526—PROCEEDINGS U. S.

Dorsal ray quadridigitate, externo- dorsal slender, postero-lateral and medio-lateral stout, subequal, externo-lateral more slender, ventrals subequal, stout, separated to base. Spicules long, slender, simple, gubernaculum small, simple. Vulva just before anus, vagina short, ovejector, and sphincter mus- cles not developed, uteri two and convergent. Eggs oval with thin shells, not embryonated within uterus. Genotype.—Sauricola sauricola, new species. As may be seen from the above diagnosis, this genus is rather closely related to the oesophagostomes, or nodular worms, from which it differs in the very short and thick esophagus, the absence of cervical papillae, the position of the excretory pore and the con- vergent uteri without muscular ovejectors. Apparently, this worm does not produce nodules in the intestine of the host. SAURICOLA SAURICOLA, new species. Specific diagnosis —Sauricola; body cylindrical, tapering slightly at extremities. Cuticle about 30y thick, with very coarse transverse striae. Mouth short, chitinous framework of buccal capsule 100v. in outside diameter, walls 15y thick and 22u high. Outer leaf crown of short and broad elements, inner crown of long slender acutely pointed blades which project beyond the opening of the mouth. Eighteen elements in each crown (fig. 1). Lateral papillae stout, each with an internal process at apical third. Esophagus 300y. long, (fig. 2), 170p thick, walls in anterior part thickly studded with stout conical teeth, nerve ring 180y behind the buccal capsule. Excretory pore 570y back of mouth collar. Intestine composed of two layers, a thin inner chitinized layer 5y thick and a thick outer muscular layer of varying thickness, averaging 50y in thickness. Lumen of in- testine of large diameter, about 50u. Male.—Tips of the inner of the four subdivisions of the dorsal ray reach the edge of the bursal membrane. Ventral rays separate near their origin (fig. 3). Externo-lateral arises near base of the com- bined medio- and postero-laterals. Separation of medio- and pos- terio-laterals occurs slightly beyond apical third of length. There is a dorsal process from the main trunk just before the separation of the lateral rays, as in Ocsophagostomum radiatum, Externo-dor- sal arises near base of dorsal trunk, which bifurcates at the middle of its length. Spicules (fig. 4) slender, equal, 2.36 mm. long. Guber- naculum 68» long. Female—Similar to male in size and general conformation. Pos- terior extremity of worm (fig. 5) mucronate, external opening of alimentary canal opens 115y in front of the extreme apex of worm, external cuticle extends 140y. into the worm to the true anus. Vulva opening 140y in advance of the external opening of the intestine. Art. 13. NEW NEMATODES FROM LAND-TORTOISE—CHAPIN. 3 Vagina 1.5 mm. long, muscular but without muscular ovejector or sphincter.

Buccal capsule (fig. 6) surrounded by a chitinous ring; 10p. deep by about 40y. across. Leaf crown single, composed of eighteen slender leaves, each leaf with conspicuous angular bend at about the middle. Esophagus about 370u long, slightly enlarged posteriorly, lumen with three longitudinal rows of chitinous bosses, extending through the anterior three-fourths of the length. Nerve ring just in front of the middle of the esophagus. LExcretory pore at or just behind the esophago-intestinal valve. Cervical papillae conspicuous, about one-fourth length of esophagus behind its poste- rior extremity. Intestine slender, with a few small caecal dilations towards the posterior end, especially in the female. Male.—Bursa (fig. 7) feebly trilobed, dorsal ray normally divided into three trunks, each of which may, and usually does, bifurcate.

Postero- lateral and externo-lateral rays stout, medio-lateral more slender and joined at its base with the externo-lateral, tips of medio-lateral and externo-lateral approach one another. Ventrals similar and parallel, their tips approximate. Prebursal papillae absent. Spi- cules (fig. 8) slender, similar, 1.54 mm. long, each with a lateral ala which commences just behind the apex and travels in a long spiral about the spicule, completing three-fourths of one complete circuit. 1No mature females available for study. + PROCEEDINGS OF THE NATIONAL MUSEUM.

Whether the nematode found in Testudo graecca of Europe is the same as Ascaris holoptera Rudolphi is another question but the great difference in the habits of the hosts would lead one to suspect a misidentification. Superfamily OX YUROIDEA. Family OXYURIDAE. Genus LABIDURIS Schneider. LABIDURIS GULOSA (Rudolphi). Syn.: Labiduris zschokket Linstow. Many hundred specimens of a worm which I refer to the above species were collected from the intestine (colon?) of Zestudo dentic- ulata. An examination of the specimens shows a great range of variation in the length of the spicules, length of the acute tail and position and number of the preanal papillae. In ten male speci- mens selected at random, the spicules measured from 0.48 mm. to 0.60 mm. The acute portion of the tail may be as short as the dis- tance from the opening of the cloaca to the base of the tail or more than twice that length. In front of the cloaca there may be as many as five papillae in each of the submedian rows with either none, one or two on either side of the rows. There are, however, usually three papillae in each submedian row. The points of difference between Z. gulosa (Rudolphi) as de- scribed by Schneider and ZL. zschokkei Linstow, as brought out in von Linstow’s original description are (1) tail long in Z. gulosa and short in L. zschokkei and (2) one papillae outside of either sub- median row in the former, two in the later. As these differences do not appear to hold in a large series, I am placing von Linstow’s species in synonymy. Both species were described from TZestudo tabulata, which equals Testudo denticulata.

A REMARKABLE NEW GENUS AND SPECIES OF MER- MITHID WORMS FROM JAMAICA. By G. STEINER Of the Bureau of Plant Industry, United States Department of Agriculture. On September 29, 1922, the Federal Horticultural Board, through the kindness of E. R. Sasscer, submitted five Mermithid specimens taken at Philadelphia, Pa., from soil about plant cuttings from Jamaica by Inspector C. A. Davis on September 25, 1922. These tive Mermithids all belong to the same species, which is new to science, and is the representative of a new genus, remarkable in several respects. Our knowledge of the Mermithidae is still very limited. This family of parasitic nemas is of high economic im- portance and much more interest should be taken in it. ALLOMERMIS,! new genus. Diagnosis—A genus of the family of Mermithidae with only four head papillae, with a mouth opening lying ventrad behind the head papillae, with amphids (lateral organs) near the front of the head- end and so lying farther forward than the head papillae, with a single dorsal suspensory or retractory muscle on the oral part of the oesophageal tube, with a vagina bent in a transverse plane of the body, with a pair of spicula and the cuticle with cross-fibers. Type species —Allomermis trichotopson? new species. The genus is closely related to Paramermis, but differs from it in having only four head papillae, whereas Paramermis has six; it differs also in having in the male two spicula while Paramermis has only one. The presence of cross-fibers in the cuticle is also a distine- tive character since no Paramermis hitherto described has them. The genus Pseudomermis, which has the same number of head papillae as Allomermis (only four), differs in the position of the amphids. In Pseudomermis they have the normal position behind the lateral papillae and the mouth opening has its normal place on the front of the head-end. Therefore the new genus Allomermis seems to be well separated and distinetly different from any other hitherto described Mermithid genus. As to relationship, it stands next to Pseudomermis. Consid- ering the fact that Al/omermis has the mouth opening and _ the 1 ad\d\os — otherwise, differently. 2 tpixwTos =—hairy, you — egg. No. 2527—PROCEEDINGS U. S.

VOL. 65. amphids shifted as in some forms of Paramermis, one might regard it as being closer to this genus, but the paired spicula and the num- ber (four) of the head papillae speak against such a relationship.

The size of this species if compared with that of other Mermithids is rather small. The cuticle was detached from the hypodermis and so its thickness could not be exactly measured. On the surface is a layer of cross-fibers. The hypodermis has apparently eight longitudinal chords,’ of which the lateral, measured on the surface, are about 42 microns wide, the dorso-medial about 8 microns, the ventro-medial and the four submedial 3-4 microns; it seemed that all of them are about equally distant from each other. The head-end is bluntly rounded as shown in Figures 1-4. Its structure is very characteristic. The mouth opening is situated some distance behind the head papillae and has therefore a decidedly ventral position. JI know no other nema with such remarkable loca- tion of the mouth opening. Some species of the genus Paramermis have a shifted mouth opening, but there it still les between’ the anterior extremity and the circle formed by the papillae. Only in P. gastrostoma, a species described earlier by the writer, and in P hempeli, described recently by Micoletzky, and closely related tc P. gastrostoma, is the mouth opening situated on the same level witl the head papillae. 3 Proposed by Doctor Cobb for use in place of the rather unsatisfactory term “ longitu- dinal fields’; it may be used in the same way as the German term ‘“ Lingswiilste.” ArT. 14. A NEW MERMITHID WORM FROM JAMAICA—-STEINER. 3 But this is not the only peculiarity in the structure of the head- end. Whereas the mouth opening is shifted backward and down from the top of the head, two other organs, namely the amphids, are shifted forward and nearer to the top of the head. These amphids lie throughout the nematode class laterally behind the head papillae. As far as I know only the above-mentioned Paramermis, species which have a shifted mouth opening, have also shifted amphids; in these species they are found on the same level with the head papillae or even a little farther forward. But Allomermis trichotopson rep- resents in this transformed arrangement the extremest case, the mouth opening located farthest caudad, the amphids, farthest for- ward. There are four submedian head papillae situated at the normal place. The mouth opening is a rather narrow, thin-walled channel through the cuticle and lower subcuticle layers, leading to the begin- ning of the cutinized esophageal channel (fig. 1). The latter at its beginning is dorsally attached by a rather strong muscle passing obliquely caudad and dorsad. This muscle certainly functions in a double way, as suspensory muscle for the end of the esophageal channel and as a retractor muscle. A protractor muscle is appar- ently not needed because of the elasticity of the skin, the exoskeleton. The amphids are, as shown in Figure 6, pouch-like organs; the bot- tom of the pouch is connected with a nerve and with what seems to be a glandular cell; from the bottom of the pouch, which is per- forated, rise the terminals, thread-like end organs of the nerve, which are perhaps chemical in function. There is a difference between the amphids of the male and female in so far as those of the male are larger; such a sexual dimorphism is not uncommon among Mermithids. The length of the esophageal tube could not be determined, but it probably runs down to near the vulvar opening; I could follow it near to the midst of the anterior uterus. The so-called fat body is filled with rather small globules so that the cell walls even in the cleared specimens could not be distinctly seen. Opposite the vagina the fat body was separated, perhaps to give space to the sexual organs. The vulva is a cross-fissure (fig. 7) leading into a tubular sigmoid vagina bent in a transverse plane of the body. Numerous, chiefly circular, but also longitudinal, muscle fibers form the wall of the vagina. This latter opens at right angles into the uteri which are outstretched forward and backward. The structure of the two ovaries and their outlets could not be seen, but each ovary is bent backwards and its end may lie at half the distance to the vulva. A great number of very typically formed eggs were in the uteri. They were spherical, had a rather strong shell covered with numerous 4 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, 65. hair-like processes, or perhaps even prickles (fig. 9). There is no other JZermis known as yet with such eggshell appendages. The female tail end is represented in figure 10; it has the same blunt ending as that of the male (fig. 11) ; the female specimen whose tail end is sketched is shghtly intersexual as shown by the presence of male papillae near the end. The male tail end is shown in figures 11 and 12. There are two spicula, rather short, shghtly curved; the retractor muscles are to be seen on figure 12 and the protractores on figure 11. The male papillae ave arranged in three double series, the longest ventro- medial, the two others submedial (fig. 12). Type.—U.S.N.M., Helminthological Collections No. 26078; para- tvpes No. 26079.

THE MAGIC, PSYCHIC, ANCIENT EGYPTIAN, GREEK, AND ROMAN MEDICAL COLLECTIONS OF THE DIVI- SION OF MEDICINE IN THE UNITED STATES NA- TIONAL MUSEUM By CHarLtes WHITEBREAD Assistant Curator, Division of Medicine, United States National Musewm INTRODUCTION. The origin of the materia medica collection of the United States National Museum dates back to 1881. In 1882 the drug collection which had been exhibited at the Centennial Exposition at Phila- delphia in 1876 was transferred to the Museum by the Department of Agriculture. For a time the efforts of the section of materia medica were confined almost exclusively to procuring authentic specimens of medicinal materials. Some years later the scope of the section was enlarged to include exhibits visualizing the history of the healing art, and in 1898 the more comprehensive name of division of medicine was substituted for the “ section of materia medica ” theretofore used. The scope of activities of the division was again enlarged in 1916, this time to include the history of pharmacy, public hygiene and sanitation, and the division, which up to that time had been administered under the department of anthropology, was made a unit of the department of arts and industries. The materia medica collection has served the purpose of giving the general public an easy reference to specimens of “ official” me- dicine and has afforded students of medicine and pharmacy the opportunity of studying this subject in its various details. The subjects of history of pharmacy, public hygiene and sanitation, be- cause of their comparatively recent addition to the activities of the division, have not progressed to the same degree of perfection as the materia medica and history of medicine collections, but with the cooperation of the various government departments and outside agencies interested in these subjects, extensive plans for their de- velopment are now under way. This paper has been prepared to meet the demand for labels and information concerning the historical medical collections, and to No. 2528.—PROCEEDINGS U. S.

In en- deavoring thus to carry into effect the purpose of the Smithsonian Institution, “the increase and diffusion of knowledge among men,” it has been considered preferable to describe small groups of related exhibits in detail rather than to compile a larger and more complete list which would necessarily be limited to very meager information. The collections herein described are located on the east gallery. Arts and Industries Building. Plate 1 gives a view of one side of the gallery.

These agents or influences are brought into action by invocations, sacrifices, incantations, and ceremonials of rarious kinds. In so far as these magic arts produce physiological and remedial effects, which they undoubtedly sometimes do, they might be classi- fied under the head of psychic or mind medicine, the mental state aroused by a firm belief in their efficacy causing modifications of physiological function and even tissue change. Magic medicine is especially characteristic of the earlier stages of human development, when all natural forces were personified, and disease and death believed to be caused by malignant spirits. Wig. 1.—INDIAN MEDICINE MAN’S RATTLE. The collection only outlines the subject of magic medicine, which covers a wide field for investigation and illustration. Exorcism.—Casting out evil spirits by religious or magic for- mulas or ceremonies. A mode of healing the sick as old as the history of medicine. Has been practiced by the people of all ages and in all stages of civilization. It is still an authorized religious ceremony.

The doctor invokes the aid of the Red Dog of the East, the Blue Dog of the North, the Black Dog of the West, the White Dog of the South, and finally the White Terrapin of the Mountain, in separate prayers.

Incantations.—Magical words said or sung. A mode of treatment employed by the Persians and Greeks, and transmitted by tradition down to the “ folk-medicine” of the present day. Abracadabra.—This Was one of the most famous of the ancient incantations employed in medicine. Its mystic meaning has been the subject of much in- genious investigation, but even its derivation has not been agreed upon. The first mention of the word is found in the poem ‘“ De Medicina Praecepta Sal- uberrima,” by Quintus Serenus Samonicus, a noted physician in Rome in the second and third centuries. In addition to being used as an incantation it was used as an amulet or charm. ‘“* Write several times on a piece of paper the word ‘Abracadabra,’ and repeat the words in the lines below, but take away ‘PR ACCA.

Take these away ever, but keep the rest until the writing is reduced to a narrow cone. Remember to tie these papers with flax and bind them round the neck.” After wearing the charm for nine days it had to be thrown over the shoulder into a stream running eastwards. This incantation and charm was believed to be beneficial in treating fevers and various other diseases (fig. 3). Incantation.—‘A prayer and incantation for visiting of sick folkis.” Used by Agnes Sampson, a famous witch of England, who was burned in 1590. “All kindis of illis that euer may be, In Chrystis name I conjure ye, I conjure ye, baith mair and less, By all the virtues of the mess, And rycht sa, by the naillis sa, That naillit Jesu, and na ma, And rycht sa by the samyn blude, That reiket ower the ruthful rood, Furth of the flesh and of the bane, I conjure ye in Goddis name.” 6 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65 Amulets and charms.—Amulets are material charms whose purpose is to protect the wearer against real or imagined dangers—witch- craft, evil eye, sickness, disease, acccidents, ete. They are of various kinds and formed of different substances: Natural, as stones of a peculiar shape, roots, leaves, seeds, horns, teeth and claws of animals. various metals, etc., or artificial, as rings, strings, representations of the hand, eye, crescent, beads, etc., and written charms, quotations from sacred writings. The use of charms is practically world-wide, wherever the belief in witchcraft, evil eye, and demons is specially pronounced. But they are in special favor with the eastern nations and are very common in Mohammedan countries. The Mohammedans frequently use as amulets either a small copy of the whole Koran, the sacred book of the Mohammedan religion, or certain portions of it. The writing is covered with waxed cloth to preserve it from ac- cidental pollution, and inclosed in a case of gold or silver, which is attached to a silk string, or a chain. Peony root.—Carried in the pocket as a preventive of insanity. The root, or a necklace of beads, is suspended from the necks of children to prevent convulsions, and to cure epilepsy. Cat.

Scutellum with two bristles, opaque upon the middle, with a thin, almost imperceptible coat of ART. 16. NORTH AMERICAN SCELLUS—GREENE, 5 white dust, bright on the sides. Pleurae bronze-black, on the upper half with a dusky copper-colored reflection, on the lower half with a thin gray-whitish dust. Abdomen brilliant coppery-red, in a certain light it appears brass-colored upon the posterior seg- ments, in an oblique direction even green; its first segment almost reddish-violet. The upper appendages, peculiar to the males of Scellus, are of a very considerable length, white, near the root black, somewhat enlarged at the tip, curved toward each other and of a yellow color, at the extreme tip black and provided with a tuft of pale hairs, which are turned backward. Coxae black, with a thin white-grayish dust, the foremost with extremely short pale hairs, with a few stiff black little hairs and near the tip with a few black bristles. Feet black, the femora more metallic green-black, with coppery reflections; the fore femora short, but very much thickened, toward the basis on the whole underside beset with bristles of dif- ferent length, on the anterior side with a row of stiff black bristles; middle femora elongated, thin, gently curved, on the underside almost entirely bare; the hind femora near the basis of the under- side are enlarged into a large, blunt appendage, beset with large black spines, beyond this appendage there is an archlike excision; then again they are stouter and beset on the underside with black bristles. The fore tibiae, which are comparatively stout, bear on the front side, not far from basis, a stout black thorn, their tip is elongated into a coarse tooth and their underside, which is beset with black bristles, has somewhat before this tooth a small ex- cision; middle tibiae long and rather slender; their first half has only three short bristles; the second is fringed on the front with a row of short black bristles; upon the posterior side somewhat beyond the middle, there are a few long black bristles, and between these and the tip of the tibia, some long, curly black hairs. The hind tibiae are much stronger than the middle tibiae, their first half is stouter than the second and the front side before the tip is armed with a strong black bristle. Tarsi plain, their joints of decreasing length, the first joint of the middle tarsi with a few bristles. Hal- teres brownish-black. Wings blackish, all their veins broadly margined with black; the margins of the costa and of the first four longitudinal veins are entirely confluent, so that the anterior part of the wings appears altogether black; upon the middle of the posterior transverse vein and upon the curve of the last segment of the fourth longitudinal vein there is a black spot; the costal cell is of a dark brown color. ‘* Female——The only female which I possess is not as well pre- served as the described male, especially the characters of the face can not be recognized with certainty; I would therefore recall the 6 PROCEEDINGS OF THE NATIONAL MUSEUM.

Front with whitish dust. The ground color of the thorax is of a coppery-bronze; upon the middle of the upper side more of a blackish-bronze, but almost everywhere so thickly covered with dust that the coppery luster is only very little perceptible; the dust on the upper side of the thorax is snow-white, upon the two longitudinal stripes near the lateral margin it is less thick, so that the coppery reflection of the ground-color is more dis- tinct; upon the middle there are two narrow, dark longitudinal lines, close to each other, which do not reach as far as the posterior margin of the thorax. Upon the pleurae the color of the dust is more yel- lowish. The scutellum has two bristles, is rather opaque, with a thin whitish dust. Abdomen green, mostly with a coppery luster, which becomes much more bright near the lateral margin. The anal ap- pendages are of middling length, white, near the basis of the lower margin with a narrow black border, and on the upper margin usually marked with a black spot; beyond the middle they are inflected up- ward and gradually assume a yellow color; their extreme tip is marked with a small brown spot and bears a small tuft of delicate pale hairs, which are turned backward; about the middle of the interior margin there is a similar pubescence; between them, toward the anal region, there is a small tuft of delicate whitish hairs. Coxae bronze-black; the four anterior with yellow and the two hind ones with a rather whitish dust; the fore coxae with very short and deli- cate pale hairs, near and upon the tip with a few black bristles. Feet black, femora and tibiae more black-green, the former bright cop- pery. Fore femora short, toward the basis very much thickened, beset on the under side with bristles of different length, on the front side with a row of stiff black bristles. Middle femora long, stronger than in S. ewustus and more curved, on the latter half of the under side with erect black bristles. Hind femora of a plain structure, not stouter than the middle femora; their under side has only, close be- fore the tip, a few black bristles. The comparatively stout fore tibiae have on their front side, not far from their basis, a stout black thorn; their tip is elongated into a very stout tooth, before which the under side of the tibiae, which is beset with strong bristles, has a small excision. Middle tibiae not quite so long and slender as those of S. exustus, on the upper side only with three or four short bris- tles, on the under side with a row of extremely long, straight, erect 8 PROCEEDINGS OF THE NATIONAL MUSEUM.

Hind tibiae plain, scarcely stouter than the middle tibiae; on the upper side, not far from the basis, there is a strong bristle, and on the latter half a few small bristles; the under side is beset with short small bristles, which are isolated upon the first part and closer together and in more regular order upon the second half; at the end of the under side there is a considerable number of less strong and less short bristles, of which the last is distinguished by its greater length; on the outside of the tip of the tibiae there are several short and one longer and curved bristle, which has almost the thick- ness of a thorn. Tarsi plain, the joints of decreasing length, the first joint of the fore and of the middle tarsi with more, that of the hind tarsi with less bristles. Halteres yellowish-brown, the lower part of the knob more dark. The wings of uniform breadth and at the end more rounded than in the other species; an uncommonly large black spot covers their apical half with the exception of a broad gray border on the posterior margin, and extends as a broad cloud along the fifth longitudinal vein almost as far as the anal cell; inside of the discoidal cell it is somewhat paler, otherwise, however, so dark that the two black spots, peculiar to this genus, upon the posterior transverse vein and upon the last segment of the fourth longitudinal vein, can only be perceived when the wing is held toward the light; the anterior part of the wing from the basis as far as the middle is dingy-whitish hyaline; the anal angle and a broad border along the posterior margin are more hyaline-gray.” Habitat.—Fort Resolution, Hudson Bay Territory (Kennicott). “ Female—It is distinguished from the male by the following characters: Face with pale yellow-grayish, front with brown dust. The middle of the upper side of the thorax with yellow-brownish dust, marked with a few spots of whitish dust. Its lateral stripes are covered with brown, the edge of the lateral margin, however, again with gray-whitish dust. The abdomen is more green, less coppery and less bright than in the male. The dust upon the pleurae and upon the fore coxae is less yellow. The fore femora are of a similar structure as those of the male; the fore tibiae without a thorn on the inside, elongated at the tip in a much smaller and sharper tooth, before which there is no excision; otherwise the feet are plain, the middle and hind femora straight and much more slender than in the male; middle and hind tibiae only sparsely beset with scattered bristles. “ Observation.—As I do not possess a North American female of S. spinipes, I have prepared the above description from Swedish specimens.” Type locality Lapland.

Three males found resting on stones on hillsides. This species differs from S. jilifer Loew (Fort Resolution, Hud- son Bay Territory) in the coloring of the wings, which have no longitudinal gray streaks between the veins, the color of the anal appendages, which are not yellow at the end, etc. Nevertheless, the resemblance between the two species must be very great.

Basal portion rather thick; last section slender, curved about its middle. “Thorax cupreous bronzed, rather thickly grayish pollinose, but not completely obscuring the ground color, dorsum with two nar- rowly separated median brownish stripes, abbreviated behind, and an obscure similarly colored stripe above the wings. Each of the few hairs arises from a black spot. Pleura much less densely pollinose. Scutellum moderately pollinose. “Legs black, femora bronzed, tibiae more greenish. Fore femora thick basally, gradually tapering. Anterior tibiae with the sub- basal spur black, its upper surface yellow pollinose, and with pale yellowish hairs; just below the origin of the spur, on the outer side a long black spine, with a shorter one above it; apex of tibiae pro- duced as a rather broad, blunt lobe, which is of about the same length as the last tarsal joint; the lobe behind with three or four Bie bristles, its anterior and apical margin with 4" fringe of short, black hairs; immediately above the lobe in front the tibia is fringed with valley hairs, dense and longer apically; beneath toward the front is a row of black bristles, longer apically, behind, on the swollen subbasal fourth with much longer bristles. Front basitarsi postero- ventrally, just before the middle, with a long bristle and two or three short ones before it on posterior surface. Middle femora strongly arcuate, the apical two-thirds swollen, beneath, on the hind surface with a single row of black bristles, but these are mixed with the long, bristly hairs on the upper half, and not distinguishable; anterodorsally is a row of five or six bristles on the apical third.

Coxae grayish-white pollinose, with fine yellow pile, the front ones with a row of black bristles. “Wings largely clear hyaline, but beyond the middle the cells are cinereous, fading out apically; on the cross-vein is a double, fused spot occupying all either end, and a second spot on the curve of the Jast section of the fourth vein; there is also a streak in the discal cell, and the area behind the fifth vein from the tip of the sixth vein is darker, but fades out marginally. ‘Abdomen on basal four segments and side of the fifth, coppery, the fifth and sixth bronze green; except the sixth segment, rather abundantly yellowish-gray pollinose. Fillaments black basally, be- coming brown, the apical half yellow: the basal portion, which is directed to the upper margin of the abdomen and about one-fifth of the second portion, which is directed backward, is black; from there to about the second third of this portion it is yellowish brown, the last third yellow; the second portion is terminated in a broad, in- ferior ciliae of yellow hairs, which extend all along the yellow por- tion, and the third portion curves obliquely upward from this point, again curving back, but the pointed end curved a little upward; the outer upper margin of the last section, not reaching to the tip, is cilate, with pale yellowish or white hairs, which are directed down- ward so as to cover the whole of this side of the filament. The termi- nal lamellae are fuscous, broadened and then ending in a pair of parallel processes, which are long, flattened and subpointed, each bearing four or five not long black hairs apically. “ Holotype—Male, Saanich, British Columbia, May 17, 1919 (W. Downes), No. 554 in the Canadian National Collection, Ottawa.” In looking over the above description I find there are some details of some of the characters which have been omitted. As I had the following description written for this new species I thought it would be of interest and important enough to give it as I had intended to publish it. Medium-sized species bronze, gray dusted; wings tinged with yel- lowish-brown (more so in the female) ; antennae short and normal. Dorsum of thorax opaque, ashen gray with two approximated, par- allel, central, dark, dull brown stripes extending backward to the penultimate pair of bristles, from here the stripe is solid, dark bronze, metallic (the width of this stripe almost equal to the space between the two stripes) ; the bristles of the two central rows are each located on a brown spot; halteres yellowish white; wings more hya- line in the male, decidedly brownish in the female; the costal vein to the tip of the first vein and the entire first vein yellow, all the GREENE, 13 ART. 16. NORTH AMERICAN SCELLUS other veins are blackish; male wing has a faint double spot on the posterior cross-vein and a faint spot at the bend of the apical seg- ment of the fourth vein; female wing with the above spots much darker and a large, definite, ight spot below the fifth vein in front of the basal cell; male appendage narrow with a nearly quadrate enlargement in the middle. Length—Male, 3.5 mm. (without appendages) ; female, 5 mm. The narrow face dull ocher, broader below; front dull gray. Pleura bronze colored with a thick, opaque, gray dust; just in front of the halteres is a well-developed fingerlike tubercle. The scutel- lum same color as the pleurae and with two large bristles at the apex. The abdomen is dark, metallic bronze, not so thickly dusted as the thorax; broadly along the apical edge of the segments and toward the outer edges the dust is whitish. Anal appendages of the male white and ribbonlike on the apical half with a fine fringe of short white hairs on inner edge; basal portion is blackish; in the middle is a broad area which is nearly quadrate with a fringe of brownish-yellow hairs along the inner and outer edge, that on the inner edge is longer; other parts of the genitalia are brownish with yellow hairs. Coxae of a blackish bronze color with whitish dust. Feet black, the femora with a more coppery, the tibiae with a more metallic-greenish tinge. Fore femora much thicker at the base, on under side strong black bristles of various length. Middle femora thickened on apical two-thirds, bent inward and downward at the basal third. Hind femora thickened, the basal edge is straight, the upper edge is arched. Fore tibiae thickened on the apical two-thirds, near the basal third on the inner side is a thick spikelike projection, on the front inner side is a long bristle, numerous short thick spinelike bristles on the under and inner edge. Middle tibiae slightly thickened at base, two faint curves; on the under and outer side is a long tuft of curved hairs, more curly on outside; numerous bristlelike hairs on inner under side near the apex; on under side near the apex is a very thick spine bent at right angles. Hind tibiae normal with several short spinelike bristles on the apical third, at the apex are three thick bristles, one is sharply bent at apex. Tarsi all simple, black; front metatarsus with a long bristle on the under side below the middle; middle metatarsus has several heavy bristles on under side, four very long ones are arranged in a row. Wings faintly infuscated on the apical half from the fourth vein to the costa, a small cloud near the middle of the outer section of the fourth vein and a cloud on the third cross-vein. The first vein entire and the costal vein from the tip of the first vein to the base is pale: yellow, all the other veins brownish-black. Hal- teres yellow with base of stem blackish. Tegulae and cilia pale yellow. 14 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. Type locality.—Saanich, British Columbia, May 17, ‘1919, W. Downes. Distribution.—W hitehall, Montana, July 11, 1917, H.

Long. corp. 0.15. Long. al. 0.20. “The narrow face is ocher-yellow. Antennae black. Front with white dust. Thorax blackish-bronze colored with copper-colored reflections; on the upper side with thick whitish dust, which almost conceals the ground color, opaque; upon the pleurae with a somewhat thinner dust of the same color. Upon the middle of the upper side there are two narrow parallel lines of a darker color, which do not reach as far as the posterior margin of the thorax. The scutellum, which has two bristles, is of the same color as the pleurae. ‘The ground color of the abdomen is like that of the thorax, is, however, more distinct, not being so thickly covered with dust; toward the lateral margin of the abdomen, where the dust almost entirely dis- appears, there isa bright copper-colored luster. The anal appendages of the male, which are turned upward at the tip, are not ribbonlike, as in the previously described three species, but filiform, white, black at the root, at the tip pale yellowish to a small extent; on the middle of their exterior margin there is a dense beard of delicate little white hairs; there is no tuft of hairs at their tip. Between them, in the anal region, only a moderate number of short delicate little hairs, which may be easily overlooked, are inserted. Coxae of a blackish- ART. 16.

Feet black, the femora with a more coppery, the tibiae with a more metallic-greenish, tinge. _ Fore femora rather strongly thickened toward the basis, on the under side with strong black bristles of different length, on the front side only with an imperfect row of short black bristles. Middle femora moderately thickened and strongly curved, on the under side of the basis with two or three not very long, on the apical half with a large number of long, straight and erect bristlelike black hairs. Hind femora plain, of middling stoutness, on the under side with bristle- like short hairs; on the upper side with two longer black bristles, of which the larger is not far from its tip. Fore tibiae strong, with a large and sharp thorn on the front side, not far from the basis; elongated at the tip into a large clumsy tooth; the under side of the tibia, provided with bristles, has no distinct excision before this tooth. Middle tibiae long, straight, a little stronger in the neighbor- hood of the basis; the first two-thirds of their under and posterior side are fringed with long curly black hairs, the end of the under and front side, however, with long and stiff black bristles; on the under side, where these bristles begin, there is between them a some- what curved black thorn. Hind tibiae straight, on the under side with short but very strong black bristles, one of which, being not far from the tip, is remarkable for its greater length; on the outside of the tip of the tibiae a few shorter and one somewhat longer curved bristle are inserted. Tarsi plain, their joints of decreasing length; the first joint of the fore and middle tarsi on the under side with black bristles, which are of considerable length near the basis of the tarsi, but decrease in length very rapidly so as to be very short on the larger portion of the joint; the under side of the first joint of the hind tarsi is everywhere beset with short black bristles. Halteres pale-yellowish, but the basis of the knob somewhat brownish. Wings hyaline; almost the whole basal third appears somewhat whitish when seen in a certain direction; grayish stripes along the second half of the second and third longitudinal veins, likewise along the tip of the last segment of the fourth and the greater portion of the fifth longitudinal vein; there is also a gray streak between the third and fourth longitudinal veins; upon the posterior transverse vein there is a blackish-gray double spot, and upon the middle of the last segment of the fourth longitudinal vein there is a larger rounded blackish- gray spot, which is less sharply defined on the side turned toward the tip of the wing.” Habitat—Fort Resolution, Hudson Bay Territory (Kennicott).

Long. corp. 0.17. Long. al. 0.21. “ Male.—Face somewhat broader than in the previous two species, dusted with bright ocher-yellow powder, opaque. Front with white dust. Antennae black. Most of the upper side of the thorax bright bronze-black with faint viclet reflections; its whole margin has a rather broad border dusted with a whitish-gray powder, and there- fore opaque; there is also a narrow middle line, which is much abbreviated behind and likewise dusted with a white-grayish powder. The upper part of the pleurae, from the shoulder to the root of the wings, is entirely without dust, metallic greenish-copper colored, very much shining; as I have only a single specimen, I am unable to judge with certainty whether this large shining spot is also present in fresh specimens, as I believe it to be, or whether in the above-de- scribed specimen it is merely rubbed off; the other parts of the pleurae are dusted with gray. The scutellum, which has two bristles, is greenish-bronze colored and opaque. The very shining abdomen is of a bright coppery color, but assumes, when its surface arr. 16. NORTH AMERICAN SCELLUS—GREENE. 17 is looked upon in a very oblique direction, a green or at least brassy- yellow color. The tapelike anal appendages are very long, somewhat blackened at the basis, and still more so at the tip which is turned upward and there beset with a small tuft of blackish hair directed backward; otherwise their margins are not hairy, although there is a single black bristle where the blackening of the tip begins on the under side in the vicinity of its inner margin. Near the anus be- tween the above-mentioned two appendages there are a few small black hairs. Coxae greenish-black, with white-yellowish dust; the foremost have, besides some pale hairs, almost imperceptible on ac- count of their shortness and delicacy, a few black bristles before and upon the tip. Feet black with a metallic-green reflection, which gradually disappears upon the last joints of the tarsi. Fore femora toward their root not so much thickened as in the two preceding species, beset with strong black bristles of different lengths on the under side, on the front side with a sparse row of short black bristles. Middle and hind femora long, slender, straight, of a plain structure, beset cn the second half with a moderate number of short, scattered black bristles. ‘The moderately stout fore tibiae bear on their anterior side, not far from the basis, a short black thorn and are prolonged at their tip into a large, somewhat clumsy but sharp tooth, before which the under side of the tibia, provided with bristles, has a very small excision. The middle tibiae are long and slender; on the upper side they are beset with only three, on the anterior side with about seven scattered bristles of very moderate length; on the other half of their hind side they bear long curly black hairs. Hind tibiae slender, straight, rather long, only on the second half with a few isolated black bristles; the bristles on the outside of their tips are also only short. Tarsi plain, their joints of decreasing length; the first joint of the fore and middle tarsi on the under side with numerous black bristles, the first joint of the hind tarsi only with a few and much shorter bristles. Wings hyaline-gray, somewhat darker toward the tip on account of the gray margin of the second, third, and fourth longitudinal veins; upon the posterior transverse vein and upon the middle of the last segment of the fourth longitudi- nal vein there is a gray-blackish spot of considerable size.” Habitat—F¥ort Resolution, Hudson Bay Territory (Kennicott).

By Crypr C. Haminton, Associate Entomologist, University of Maryland. INTRODUCTION. Larvae of the Cicindelidae were first noted in literature as early as 1798. The first work of importance is that of J. C. Schiodte: De Metamorphosi Eleutheratorum observationes, Carabi. in 1867. His observations, descriptions, and figures of Cicindela hybrida and C. campestris are excellent. George H. Horn, in 1878, gave a detailed description of a larva from each of the four genera occuring in the United States. His descriptions are too general to be of much morphological or taxonomical value. During the same year and several succeeding years F. G. Schaupp published a number of notes on tiger-beetle larvae. From this time until 1905 very little attention was given to the study of the larvae. In 1907 Dr. V. E. Shelford published in the Biological Bulletin an excellent account of the habits and distribu- tion of a number of the species occurring in the vicinity of Chicago, Illinois. The following year he published on the life history and habits of these same species and considered their relation to hiberna- tion, depth of burrow, moisture, temperature, etc. In later papers he has made detailed comparisons of the ecology of the larvae of the same species and of different species from widely separated regions. During 1907 and 1910 Norman Criddle published in the Canadian Entomologist excellent accounts of the habits and life histories of a number of the species occuring in Manitoba, Canada. Some of the more interesting facts he pointed out are the increased depth of the burrow, the smaller size of the species and the lengthening of the life history, due to the long severe winters and short summers. An interesting paper on the habits of Amblychila cylindriformis was published in the Entomological News for 1914 by F. X. Wil- liams and H. B. Hungerford. The most comprehensive work on all stages of the Cicindelidae, however, is that of Walter Horn, pub- lished in the Genera Insectorum. He discusses practically every No. 2530.—PROCEEDINGS U. S.

The present paper is a revision and an addition to work done in 1916 at the University of Illinois for a Masters Thesis. As pre- sented at that time it consisted solely of the part on the classification of the larvae. The work was done under the direction of Prof. A. D. MacGillivray who gave many helpful suggestions and criti- cisms. A study of the larvae was made possible through the opportunity for the purchase of a collection of determined material from Dr. V. E. Shelford and, unless otherwise stated, the larvae were col- lected and reared by him. He also permitted me to use his unpub- lished notes and gave numerous suggestions on the habits of the larvae. I am indebted to Prof. S. A. Forbes and the Graduate School of the University of Illinois for securing this collection. The scope of the paper was considerably extended through the opportunity to study a collection of larvae of the genus Omus, together with some additional larvae of the genus Cicindela, sent to Prof. A. D. MacGillivray by Dr. F. E. Blaisdell, sr., of the Leland Stanford Junior University Medical School. Larvae of Amblychila cylindriformis were secured through the courtesy of Prof. S. J. Hunter, of the Department of Entomology, University of Kansas. From 1916 until 1922 little was done on the paper except the occasional collection of larvae. It was then decided to include the morphology of the larvae and add to the classification a number of additional species in the collection of the United States National Museum. Thanks are due Dr. L. O. Howard, Honorary Curator, Division of Insects, for permission to study this material and to Dr. Adam Boving, of the Bureau of Entomology, for assistance on the morphology. The entire larval material in the museum has been studied and revised; 17 undetermined or wrongly determined species have been named. Three species not represented in the col- lection have been given to the United States National Museum by the author. Acknowledgments are expressed to the Agricultural Ex- periment Station of the University of Maryland for the time used in revising this paper. All drawings have been made by the author. Charles Leng’s Catalogue of the Coleoptera of America North of Mexico, 1920 edition, has been followed in the nomenclature. MORPHOLOGY OF THE LARVA. The larvae of the Cicindelidae (figs. 1 to 4) are long, cylindrical, and grub-like and normally live in burrows in the soil. Some of ART. 17. LARVAE OF HOLARCTIC TIGER-BEETLES—HAMILTON, 3 the tropical species are arboreal and the larvae live in burrows in the smaller twigs. The habits of the larvae have resulted in sev- eral morphological adaptations. The head and pronotum are strongly chitinized and highly colored on the dorsal part, the meso- thorax and metathorax are much less chitinized and the abdomen is membranous with chitinized, setaceous areas. The head and _ pro- thorax are bent ventrad at an angle of about 45 degrees, the fifth abdominal segment has a prominent projection on the dorsal aspect, and the segments caudad of the fifth are curved ventrad. The mature larvae vary from three-fourths to about two inches in length. In describing the morphology of the larvae one species has been taken as the type and only a few of the more characteristic varia- tions in other species and genera have been considered. Cicindela limbalis has been chosen for this purpose since it is one of the larger and more generalized species of the Cicindela and is widely dis- tributed. HEAD. The head will be discussed under two divisions—the fixed parts or the head capsule and the movable parts or the appendages. Head capsule——The head capsule (figs. 5, 6, and 8) is heavily chitinized, slightly concave on the dorsal aspect and strongly convex on the ventral. The dorsal surface is bronze, with a bluish-green luster, the ventral surface a light chestnut brown. The head capsule is divided into two areas—the epicranium and the fronto-clypeo- labral area—by the epicranial and frontal sutures. The epicranium is divided into two halves—dorsally by the epicranial suture, ven- trally by the gular suture. The epicranial suture (eps, fig. 8) 1s on the dorso-meson and extends cephalad a short distance from the occipital foramen. From this point a frontal suture (fs, fig. 8) (=arms of epicranial suture) extends cephalo-laterad as a sinuate line to each antennal fossa. The gular suture (gus, fig. 14) 1s on the ventro-meson and extends cephalad from the occiput to the attach- ment of the labium. The occiput (oc, figs. 5 and 8) is the narrow, slightly raised, band- like sclerite extending around the caudal margin of the head capsule. It is separated from the epicranium by the occipital suture (ocs, fig. 8) and is strongly infolded on the ental surface. The epicranium consists of the following not distinctly defined regions: Vertex, genae, and postgenae. The vertex (ve, figs. 5 and 8) occupies the dorsal and lateral parts of the epicranium and ex- tends from the occiput to the frontal suture and the insertion of the mandible. It includes within its boundaries the location of the antennae and the ocelli. A prominent ridge extends cephalo-mesad from each caudal ocellus to the frontal suture. The part of the head 4 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 65, caudad of this ridge, named collwm (co, fig. 8) is strongly deflexed. The genae (ge, figs. 5 and 14) include the greater part of the epi- cranium on the ventral aspect of the head. They extend from the occiput cephalad to the postgenae, laterad and dorsad to the vertex, and meet on the meson. The postgenae (pge, figs. 5 and 14). include the ventral and lateral part of the epicranium cephalad of the genae. They extend from the genae to the cephalic margin of the head capsule, laterad to just beyond the ventral articulation of the mandible, and mesad to the hypostoma and the attachment of the eardo. The cephalic margin is inflexed and produced as a triangular projection between the mandible and maxilla, where it joins with the ventral part of the clypeus. The hypostoma (h, fig. 14) is a paired structure and consists of a V-shaped area mesad of the postgenae on the ventral aspect of the head. Its caudal extent is indicated by a short, dark, transverse bar, which is about one-third the distance to the caudal margin of the head. This transverse bar is the point of attachment of the caudal arms of the tentorium. The maxillae and labium are attached at the cephalic margin of the hypostoma. The fronto-clypeo-labral area (fela, fig. 8) is between the frontal sutures and extends cephalad to the cephalic margin of the head. It consists of the frons, clypeus, and labrum. The sutures separat- ing these sclerites are obsolete. The frons (f, fig. 8) is between the frontal sutures and is considered as extending cephalad to the ceph- alic margin of the small sclerite, the “latero-clypeus,” mesad of the antennae. Its cephalic margin is determined by the point of attach- ment of the anterior arms of the tentorium. There is a U-shaped ridge (us, fig. 8), bearing two setae, on the caudal part of the frons. The clypeus (ce, fig. 8) is considered as extending cephalad from the frons to just cephalad of the tooth-like projection on the cephalo- lateral angles. Each lateral one-fourth of the clypeus, named “ an- gulus frontalis” by Schidédte, is raised above the mesal part (af, fig. 8). The ventral surface of the clypeus is strongly joined to the postgenae ventrad of each tooth-like projection. The labrum, form- ing together with the cephalic part of the clypeus the “nasale” (Boving), is folded back on its ventral aspect to the epipharynx (figs. 7 and 8). The small, rectangular sclerite (/c, fig. 8) mesad of the antenna is considered as a lateral sclerite of the clypeus. For this sclerite I propose the name of “ latero-clypeus.” The tentorium or internal head skeleton, consisting of the anterior, dorsal, and ventral arms, is not strongly developed. Each anterior arm (aat, fig. 7) is attached along the suture separating the latero- clypeus from the clypeus and, at its cephalic end, is produced into a knob-like projection to which the dorsal acetabulum of the mandible articulates. Each anterior arm projects ventro-mesad until they ART. 17. LARVAE OF HOLARCTIC TIGER-BEETLES—HAMILTON, 5 meet and fuse with the ventral arms of the tentorium. The dorsal arms (dat, fig. 7) of the tentorium are fused with the anterior arms and, on the inner surface of the head, are attached along the caudal part of the suture separating the latero-clypeus from the clypeus. From the middle of each fused arm a free part projects dorso-caudad. These, however, do not represent the dorsal arms since they do not connect with the head capsule. The usual place in adult insects for the attachment of the anterior arms of the tentorium is at the lateral ends of the fronto-clypeal suture; and for the dorsal arms of the tentorium at some point near the antennal sockets. To a large ex- tent this same relation holds true in immature stages. In the larve of the Cicindelidae the antennae are inserted so near the cephalic margin of the frons that it leaves only a short distance between the points of invagination of the anterior and the dorsal arms of the tentorium and, as a result, the two have fused. The ventral arms (wat, fig. 6) of the tentorium have also fused through the mesal fusion of the epicranium. The invagination for the ventral arms of the tentorium is on the meson at the caudal margin of the hypostoma. It extends entad a short distance, as a strongly chitinized structure, and connects with the anterior and dorsal arms. A thin plate-like projection (fig. 6) extends caudad along the meson from the invagi- nation for the ventral arms and, at the caudo-ventral part of the head, is produced cephalad as a broad lamella-like structure. The ocelli, consisting of six pair, are on the vertex on the dorsal and lateral aspects of the head. The diameter, distance apart and comparative size of the two larger ocelli furnish excellent taxo- nomic characters. To facilitate refering to the ocelli they have been numbered, starting with the largest and numbering to the smallest. Ocellus i (01, fig 8) is large, conical and quite prominent and is on the dorso-caudal part of the head. Ocellus 2, (02, fig. 8) is similar to ocellus 1 and is located cephalad on the dorso-lateral part of the head. Ocellus 3 (03, figs. 5 and 8) is cephalo-ventrad of ocellus 2, and ocellus 4 (04, figs. 5 and 8) is caudo-ventrad of ocellus 38. The remaining two ocelli are quite small and incon- spicuous and appear as transparent convex spots. Ocellus 5 (08, fig. 5) is ventrad and slightly caudad of ocellus 2. Ocellus 6 (06, fig. 8) is caudo-mesad of ocellus 2. Movable parts of the head.—The antenna is inserted on the dorsal aspect of the head laterad of each latero-clypeus.

Measurements.—Length of larva, 15 to 17 mm., width at the third abdominal segment, 1.4 to 1.6 mm.; diameter of ocellus 2, 0.32 to 0.34 mm.; distance between ocelli 1 and two, 0.19 to 0.21 mm.; length of fronto-clypeo-labral area, 1.25 to 1.35 mm., width, 1.25 to 1.85 mm.; length of pronotum, 1.5 to 1.7 mm., width, 2 to 2.8 mm. This species is easily distinguished from all others by the two- segmented labial palpus, which has apparently occured through the fusion of the proximal and second segments. The larvae were collected at Galveston, Tex., on Denver Beach, from moist, clean sand, outside of the shrubs, which is probably covered by highest tides. It occurs in situations similar to those of C@. hirticollis along the New England coast and around the shores of Lake Michigan. The burrows are from 12 to 18 inches in depth.

The larva of this species is from India and was collected by Walter Horn. The nearest American form that I have studied is Cicindela dorsalis saulcyi and in many respects the two are quite similar. Cicindela biramosa is the larger of the two species and may be separated from Cicindela dorsalis saulcyi by the two setae on the U-shaped ridge, the ninth abdominal sternum bearing two groups of four instead of three setae each, the median hooks with three setae and the inner hooks with 8 to 10 setae.

Measurements.—Length of larva, 20 to 24 mm., width at the third abdominal segment, 2 to 2.5 mm.; diameter of ocellus 2, 0.25 to 0.28 mm.; distance between ocelli 1 and 2, 0.25 to 0.28 mm.; length of fronto-clypeo-labral area, 1.5 to 1.7 mm.; width, 1.5 to 1.7 mm.; length of pronotum, 1.8 to 2 mm., width, 2.9 to 3.2 mm. The larvae of this species can be easily distinguished from those of other species by the brown setae on the head and pronotum. The larva is very characteristic in its habitat, which is quite different from most others, as stated by Shelford (1908) : This species does not deposit eggs in pure humus, but makes use of little irregularities in clay or sand which contains a litthe humus and which is shaded slightly, such conditions as are afforded by falling trees and the erosion of hillsides by small brooks. It prefers a few loose leaves, and will lay eggs under them in preference to other places when they are present. It does not, however, appear to like very shady conditions. Several days spent in the beech and maple forests of northern Indiana has failed to reveal the presence of one of these insects, although they were present in open and partly cleared places a short distance away, where the forest has not become so mesophytic. The eggs are laid in June or early July in the shade, and the ma- jority of the larvae reach the third stage by fall. The larvae pupate the following year in July, and the adults emerge in August. In northern Illinois the adults rarely appear in autumn, and it is proba- ble that they remain in the pupal chamber until spring. There are two years between generations. Larvae were collected by Professor Shelford from Suman, In- diana, Clinton and Lafollette, Tennessee, in 1908, and by the author from Urbana, Illinois, in 1916, and College Park, Maryland, in 1922.

The larva of this species is quite similar to that of serguttata, but can be distinguished from it by the different colored setae on the head and pronotum and the longer spinelike projection on the inner hooks. This species is an European form and does not occur in the United States. CICINDELA LIMBALIS Klug.

This species is very similar to C. purpurea graminea, but can be separated from it by the larger number of secondary setae on the pro- notum, and the longer length of the spinelike projection of the inner hooks. - The adults appear from hibernation later in the spring than do those of C. purpurea graminea and the eggs are laid in June. By fall the larvae have reached the second instar, in which stage they pass the winter. They appear the latter part of the following May or the first of June, pass into the last larval instar, and pupate in July. Some of the adults emerge in August while others remain in the pupal chamber until the following spring. They reach sexual maturity in the spring about a month later than C. purpurea graminea. The larvae are found in clay on steep banks of Lake Michigan. The burrows enter at almost a right angle to the surface and curve into a nearly horizontal position at the inner end. They are from 7 to 10 centimeters deep and there is usually a chimney- like structure around the opening of the burrow which is formed by the soil excavated by the larva. Criddle (1910) states that the larvae are found at Atweme, Manitoba, in situations similar to those observed by Shelford, the depth of the burrow varying from 3 to 8 inches. The length of the larval stage is approximately 2 years and the adult stage from 9 to 11 months. In the vicinity of Chicago, Illinois, the larval stage lasts about 14 months and the adult stage 10 months. ART. 17.

The adults appear from hibernation in April, mate and lay eggs the latter part of the month. The eggs are laid in moderately moist, black soil in openings in grassy places, such as cow paths in grassy ravines and old bare places near streams. They probably lay eggs only after rain on well drained soil. The larvae reach the third instar the latter part of August or the first of September, close their burrows and hibernate.

The life history of this species as given by Shelford (1908) for the northern part of Tlinois differs from that of all others which he had observed, in that the larval stage lasts almost two years and the adult stage but a month or slightly more. The eggs are laid the latter part of July and the second instar is reached by autumn. They pass the winter in this instar, feed the next spring and summer and reach the third instar in June or July. They feed until late fall, hibernate, and come out about the first of the following May. The larvae pupate in June or July and the adults soon emerge, lay eggs and die. The species is two brooded, adults from each brood appearing in alternate years. As a result in May both second and third stage larvae can be secured, in July adults, eggs, first and third stage larvae, and in October second and third stage larvae. The fol- lowing table gives the life history and the stages present for the three most important months of the year: TABLE 1.

Criddle (1910) states that the life history of Cicindela lepida is probably the same at Aweme, Manitoba, as at Chicago, Llinois; that is, the larval stage lasts approximately twenty-two months and the adult stage two months. The eggs are laid and the larvae live in sand which is slightly shift- ing, in northern Illinois, usually near Lake Michigan, but in some cases on the tops of sand dunes one-half mile from the lake. The burrows are from 25 to about 40 inches deep in northern Illinois and from 58 to 72 inches deep at Aweme, Manitoba. 34 45554—25—Proc.N.M.vol.65 34 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65.

The larvae of this species may be distinguished from the preced- ing by the longer spinelike projection of the inner hook and the inner seta on the hook being located nearer the base than the outer seta, also by the less numerous secondary setae on the pronotum and its distinctly larger head measurements. The larvae were collected at Haswell, Colorado, on the open prairie in clay or adobe soil. The burrows occurred between bunches of grass, were about 8 inches deep, slightly spiral, and two-fifths of an inch in diameter at the bottom. Smaller larvae collected in the same situation and which appeared to be immature larvae of this species had a chimney-like structure about an inch long around the opening of the burrow. This addition was about an inch long and was built so that it was parallel to the surface of the ground. 36 PROCEEDINGS OF THE NATIONAL MUSEUM, VOL. 65. CICINDELA TRANQUEBARICA Herbst.

The life history of this species is essentially the same as that of Cicindela purpurea graminea. The eggs are laid in a variety of moist situations but are more often laid in sandy soil with some humus and in among some vegetation. The burrows are straight and from 9 to 20 inches deep. At Brandon, Manitoba, the larvae were found at a uniform depth of about 18 to 20 inches and were usually dug from sandy soil. Criddle (1910) says: ArT. 17. LARVAE OF HOLARCTIC TIGER-BEETLES—HAMILTON. ot Two distinct sizes were found among the larvae in autumn, which corre- sponded to the first and second year of venusta, so that it seems highly prob- able that the larval life lasts two years, while that of the adult continues for about eleven months.

The larvae are usually found in clay or humus. Criddle (1907) found the larvae burrowing in large numbers along the banks of a river at Awene, Manitoba, in clayey, muddy, and sandy soil. In the summer time the burrows are from 4 to 5 inches deep and in the winter time from 6 to 15 inches. The holes gener- ally slant obliquely into the bank. CICINDELA GERMANICA Linnaeus.

VOL. 65. The life history of this species as given by Shelford (1908) differs from that of other species in that the adults do not hibernate and there is only a single year required for the life cycle. The eggs are laid in relatively hard, dry soil, usually humus, the latter part of July, and larvae were dug from bare spaces between clumps of grass in the vacant lots of Chicago. The majority of the larvae are in the third instar by September, in which instar they hibernate and ap- pear early the next spring. They feed until April or early June, when they pupate. The adults emerge in early July, mate and lay egos. The larval burrows during the feeding reason are from 12 to 16 inches deep but are slightly shallower in the summer just before the larvae go into the pupal stage. This species was reared by Shel- ford, 1905 and 1906 at Chicago, Illinois. Criddle (1907) states that the larvae are found at Aweme, Manitoba, in small, mossy places be- tween clumps of grass in dry situations. The depth of the holes ranged from 18 to 26 inches. The adults do not hibernate and it is probable that the larval stage lasts over two winters. I have collected adults and dug larvae of this species from moist. adobe soil at Haswell, Colorado.

Measurements.—Length of larvae, 22 to 25 mm.; width at the third abdominal segment, 3 to 3.8 mm.; diameter of ocellus 2, 0.28 to 0.30 mm.; distance between ocelli 1 and 2, 0.31 to 0.83 mm.; length of fronto-clypeo-labral area, 1.9 to 2 mm.; width, 1.9 to 2 mm.; length of pronotum, 2.1 to 2.3 mm.; width, 3.6 to 3.8 mm. This species is easily separated from all others by the position of the cephalo-lateral angles of the pronotum, which extend distinctly cephalad of the mesal portion. The larvae were dug at Lafollette, Tennessee, from bare, rocky soil on a steep, sparsely wooded hillside. Recent burning had probably removed the leaves which normally covered the slope. The burrows were perpendicular for the first 3 or 4 inches and then curved to a horizontal position. The larvae were not bred, but all other species of the region have been.

LARVAE OF HOLARCTIC TIGER-BEETLES—-HAMILTON. 47 Larvae were collected at Salida, Colorado, in a sand dune near water along the Arkansas River and from Benkelman, Nebraska, on the south fork of the Republican River in the crest of sand dunes. At Salida, Colorado, the sand was coarse and fine mixed and had probably been deposited by high water. The holes were vertical and about 22 inches deep. The burrows have a pit similar to those of Cicindela formosa generosa found around Chicago, Tlinois, and Pines, Indiana. CICINDELA FORMOSA GENEROSA Dejean. Figs. 49, 50, 51, 88, 89, 90, and 142.

VOL. 65. of fronto-clypeo-labral area, 2.2 to 2.4 mm., width, 2.2 to 2.4 mm.; length of pronotum, 2.4 to 2.7 mm.; width, 3.6 to 4.2 mm. The larvae of this species are similar to those of Cincindela for- mosa but can be distinguished from them by the smaller average width of the pronotum, the lack of a color pattern on the pronotum and the presence of three setae on the median hooks. The adults emerge from hibernation in April or May and lay eggs in May or June in sandy soil which is slightly shifting. The eggs hatch in June and the larvae reach the third instar by the latter part of August or the first of September. They close their bur- rows the latter part of September or the first of October and go into hibernation, appearing again in the spring. Pupation takes place in June or July and some of the adults emerge from the pupal chamber during the summer while the remainder stay in the pupal chamber until the following spring. The adults appear in April or May, become sexually mature in about a month, lay eggs, and die. The larvae of this species are very noticeable because of their peculiar burrows. The main part of the burrow is from 12 to 20 inches deep and vertical throughout the greater part of its course. About two-thirds of an inch from the top the burrow curves sharply to a horizontal position and opens into a small pit. This construc- tion serves to keep the sand, which is always slightly shifting, from filling up the burrow and also serves as a trap for catching insects. The larva cements the sand immediately around the opening with saliva which keeps it from caving in. The pupal chamber is an oblique side cavity about 4 inches below the surface. The upper part and much of the lower part of the burrow is filled with sand which is taken from the cavity. Larvae were collected along the sand dunes of Lake Michigan, near Chicago, on the leeward side of the first ridge where the bunch grass has come in and the cottonwoods are old with occasional seed- ings of pine. They reach their greatest abundance among the young pines but rarely invade the denser growths. CICINDELA SCUTELLARIS LECONTEI Haldeman. Figs. 75, 112, and 143.

Measurements.—Lenegth of larvae, 20 to 24 mm., width at the third abdominal segment, 2.4 to 2.8 mm.; diameter of ocellus 2, 0.27 to 0.30 mm.; distance between ocelli 1 and 2, 0.27 to 0.30 mm.; length of fronto-clypeo-labral area, 1.7 to 1.8 mm., width, 1.7 to 1.8 mm.; length of pronotum, 1.7 to 2 mm., width, 2.8 to 3.2 mm. The life history of this species is similar to that of C%cindela purpurea graminea. The adults appear later in the spring and remain later in the summer. The eggs are laid and the larvae found in dry sand which contains some humus. Along Lake Michigan, near Chicago, the larvae were found further back than those of Cicindela formosa generosa. They were found in the greatest abund- ance where the oaks begin to displace the pines. CICINDELA CUPRASCENS MACRA LeConte. Figs. 153, 165, and 172.

The full-grown larvae used in this description were not reared but were taken from collections of Cicindela hirticollis. The first and second stages had been reared by Shelford and comparisons of these with the dug larvae permits of little, if any, doubt that the identification is correct. Shelford states that in the terrigenous margin of Lake Michigan the adults of Cicindela cuprascens are found associated with those of Cicindela hirticollis. They frequent the moist clean sand with little or no humus. He was never able to find the larvae, due perhaps to the fact that these larvae do not smooth the edges of their holes. The burrows of the reared first and second stages and the ones collected by the author are shallow and similar to those of Cicindela hirticollis. art.17.

This species is very similar to Cicindela pulchra and differs from it principally in the slightly larger size as is shown by the head measurements, the cephalo-lateral angles not extending as far cephalad as the mesal portion, a slightly different arrangement of the setae on the third abdominal segment and the form of the mesal hooks. Larvae were not reared and the determination given is not final. It is possible that the species here described may be Cicindela pul- chra and the one described as pulchra may be obsoleta. The larvae were collected at Haswell, Colorado, on the’prairie in adobe or slightly gravelly soil. The burrows were located in the bare spaces between tufts of grass, they were from 5 to 7 inches deep, slightly spiral, with the bottom often enlarged to about three-eighths of an inch in diameter. Of 34 larvae collected on August 25, 1916, 4 were parasitized with 7 parasites. Two had one parasite each, another larva had ART. 17.

The larval parasites were attached on the side of the abdomen between the second and sixth abdominal segments. No uniformity appeared to exist as to the point or method of attachment. The parasites were Dipterous larvae about one-sixteenth to one- eighth of an inch long. They are probably those of the bee-fly, Spo- gostylum anale, which Shelford describes as parasitizing Cicindela scutellaris lecontet. CICINDELA HYBRIDA Linnaeus. Figs. 154, 166, and 177. E.

Abdomen.—Chitinized areas distinct, secondary setae short, few and not prominent (fig. 93); ninth abdominal sternum with the caudal margin bearing two groups of three setae each; median hooks with two setae; inner hooks with two setae, the spinelike projection about one-fourth the length of the hook (fig. 146). Measurements.—Length of larvae, 17 to 19 mm., width at the third abdominal segment, 2.2 to 2.4 mm.; diameter of ocellus 2, 0.30 to 0.338 mm.; distance between ocelli 1 and 2, 0.27 to 0.30 mm.; length ef fronto-clypeo-labral area, 1.4 to 1.6 mm; width, 1.8 to 2 mm.; length of pronotum, 1.8 to 2.1 mm; width, 2. 9. to 3.2. mm. The larvae of this species are rather distinctive and easily recog- nized by the large number of white, flattened or scalelike setae on the pronotum. The only other American larva studied which re- sembles it in this respect is Cicindela limbata which has only about 56 PROCEEDINGS OF THE NATIONAL MUSEUM, VoL. 65. half as many setae on the pronotum and which are not so distinctly flattened. The larvae are very restricted in their habitat, occurring only in moist, clean sand which has very little or no humus, as on the beach of Lake Michigan. The burrows are vertical and about 5 inches deep. The eggs are deposited in late June or July and the larvae reach the third instar some time in September, close their burrows in October and hibernate. The burrows are opened in May of the following year and the larvae pupate in June or July. The adults emerge in August, hibernate over the winter and become sexually mature the following spring.

LARVAE OF HOLARCTIC TIGER-BEETLES—HAMILTON, 5Y fronto-clypeo-labral area, 1.45 to 1.55 mm.; width, 1.45 to 1.55 mm.; Jength of pronotum, 1.5 to 1.6 mm.; width, 2.4 to 2.6 mm. The larvae were collected at Wray, Colorado, in bare, white sand blowouts. The burrows were straight or slightly spiral, from 10 to 14 inches deep, and occurred in clusters of a dozen or more to the square foot. The larvae of Cicindela lepida were dug from the same situations. Criddle (1907) states that the larvae occur in large, sandy blow- outs with scant vegetation. They are also sometimes found in small patches of shifting soil but are always much more plentiful in white sand, which is constantly drifting. The depth of the burrows varied from 7 to 17 inches. The life cycle requires 3 years at Aweme, Manitoba, approximately 2 years are required for the larval stage and 1 year for the adult stage. He also writes that the larvae are able to withstand much more cold than the adults, the larvae remaining out until the latter part of October. 2. Genus TETRACHA Hope.

Larvae have been collected from a variety of situations and they are not as restricted in their habitat as most of the larvae of the Cicindelidae. Dr. V. E. Shelford has dug the larvae at Yuma, Arizona; Galveston and Houston, Texas; Mobile, Alabama; and Columbus, Georgia. Those dug at Houston, Texas, were taken from bare, artificially exposed soil of a fine moldable nature, not sticky. At Galveston, Texas, the larvae were dug along the beach from moist sand covered with a scattered growth of vegetation. Those collected at Columbus, Georgia, were dug from moist, clayey soil. A. H. Manee collected the larvae at Southern Pines, North Carolina, from hard, stony, and gravely soil, clayey soil, and moist, loose black soil. The openings to the burrows are large, the burrows straight or slightly inclined from the vertical, and from 8 to 12 inches deep. TETRACHA VIRGINICA Linnaeus. Vigs. 79 and 117.

Measurements—Length of larvae, 28 to 30 mm., width at the third abdominal segment, 4 to 5 mm.; diameter of ocellus 2, 0.46 to 0.43 mm.; distance between ocelli 1 and 2, 0.48 to 0.50 mm.; length of fronto-clypeo-labral area, 2.75 to 2.85 mm.; width, 2.45 to 2.55 mm.; length of pronotum, 2.9 to 3.2 mm.; width, 4 to 4.5 mm. This species is similar to 7’etracha carolina but can be separated from it by its larger size, the absence of a distinct purple color to the pronotum, the presence of a large number of secondary setae on the membranous area of the abdomen, and the different arrangement of the setae cephalad of the inner hooks and mesad of the distal halt of the median hooks. The larvae were collected at Southern Pines, North Carolina, by A. H. Manee in sandy and gravely soil, clayey soil, and in moist, loose, soil. They occurred in the same situations as 7’etracha carolina. 1 have collected larvae at College Park, Maryland, from clayey and gravely soil along paths which were not frequently used. The open- ings to the burrows are about three-eighths of an inch in diameter, the burrows are straight or slightly inclined from the vertical and from 8 to 12 inches deep. 3.

Walter Horn, in the Genera Insectorum (fasc. 82, p. 99) states that Konigsberger (1897) discovered the larva in the Botanical Gardens of Buitenzorg (Java) living in the small twigs of the coffee tree. The larva hollows out a cavity in the pith one and one-half as long as the larva itself. The opening to the outside is at a right angle and round about it the twig is somewhat thickened (fig. 190). Walter Horn also states in the Genera Insectorum (fase. 82, p. 428) that “ Keiner der Autoren hat die Larven von (. Bonelli und C. emarginata auseinander halten konnen.” Since the larva described by myself came from Horn, I am unable to say whether it is C. bonelli or C. emarginata. 4.

This genus occurs only on the Pacific coast from British Columbia to the southern part of California. There are a number of species and sub-species, the adults of which are difficult to separate. The Jarvae are also very difficult to separate, and a study of a large series would probably aid in the nomenclature of the adults. 45554—25—Proce.N.M.vol.65 36 66 PROCEEDINGS OF THE NATIONAL MUSEUM.

Measurements.—Length of larvae, 24 to 26 mm., width at. the third abdominal segment, 3.2 to 3.4 mm.; diameter of ocellus 1, 0.42 to 0.44 mm., of ocellus 2, 0.29 to 0.81 mm.; distance between ocelli 1 and 2, 0.26 to 0.28 mm.; length of fronto-clypeo-labral area, 2.1 to 2.3 mm., width, 2.4 to 2.6 mm.; length of pronotum, 2.6 to 2.8 mm., width, 4 to 4.3 mm. The larvae were collected at Licking Fork, Mokelumne River, California, at an elevation of 2,900 to 3,100 feet, by Dr. F. E. laisdell, sr., and Beverly Letcher. A single larva of Omus edwardsii Crotch, the identity of which was questioned, was secured from Dr. F. E. Blaisdell, sr.; this larva was collected in the same locality as Omus sequoiarum and seems to be identical with it (figs. 48, 87, and 122). The pronotum (fig. 87) shows a few more setae than that of Omus sequoiarwm (fig. 85), but the larvae of the later species were observed which had a similar setal plan. 6. Genus AMBLYCHILA Say.

Color.—Head and pronotum dark chestnut brown; setae brown. Head.—Setae on dorsal aspect of head long, slender, and promi- nent; ocellus 2 about one-half the size of ocellus 1; diameter of ocellus 2 subequal to the distance between ocelli 1 and 2; fronto-clypeo-labral area wider than long; transverse ridge on the caudal part of frons with 6 to 8 setae; crenulate emarginations on the anterior edge of the labrum subequal; antenna with the second segment twice the length of the proximal, three times the length of the third and ten times that of the distal segment, setae long and slender, the proximal segment with 6 to 12 setae and the second with 15 to 20 (fig. 126) ; maxilla with the proximal segment of the galea bearing 5 or 6 setae on its mesal margin; ligula with six fine setae arranged in a transverse row at its ventro-distal end, proximal segment of labial palpus with 5 or 6 setae and the distal segment with 12 to 15 (fig. 20). Thoraz—Pronotum with the cephalo-lateral angles extending cephalad of the mesal portion, lateral margins slightly carinate, setae numerous, short, and conspicuous (fig. 81). Abdomen.—Chitinized areas indistinct; setae short to long, numer- ous, and occurring between as well as upon the chitinized areas (fig. 123) ; median hooks with 18 to 20 setae; inner hooks with 12 to 15 setae (fig. 148). Measurements.—Length of larvae, 45 to 50 mm., width at the third abdominal segment, 7 to 8 mm.; diameter of ocellus 1, 0.40 to 0.45 mm., of ocellus 2, 0.20 to 0.27 mm.; distance between ocelli 1 and 2, 0.20 to 0.24 mm.; length of fronto-clypeo-labral area, 3.3 to 3.4 mm., width, 3.6 to 3.8 mm.; length of pronotum, 4.2 to 4.8 mm., width, 6 to 6.4 mm. The habits of the larvae, as given by Williams and Hungerford (1913), are as follows: They usually occur in colonies of from 2 to 11, the individual burrows being close together, often not more than 1% inches apart. Usually a colony can be circumscribed by a 10-inch radius. The larger ones (burrows) were a little less than one-half.inch in diameter and about 39 inches deep. The rim was slightly elevated above the surface of surrounding level, and the entrance art.17. LARVAE OF HOLARCTIC TIGER-BEETLES—HAMILTON. 71 perfectly circular. The burrows have quite a characteristic way of going straight down for about 18 inches and then, turning to an angle of about 45° downward, proceed about 18 inches farther. This lower portion has a tendency to be feebly spiral. The burrow for the last 10 or 8 inches is quite noticeably enlarged, especially laterally, and the extreme end is invariably packed with the remains of former repasts. The holes are generally located on the brow of a cliff, but one colony was found in muddy silt at the foot of a cliff-like bank, well below the recent flood level of the stream. Still others occurred on the high plain some half a mile back from the bluffs. Two or three were found that had their openings in the face of the cliff. These sloped back and did not conform to the normal burrows. It was often noticed that these larval burrows were situated near some larger hole, as that of the field mouse or badger.

THE SHANTZ COLLECTIONS FROM THE PIKES PEAK REGION. G. S. Dopps, Of West Virginia University. The collections of entomostraca described in this paper were made by Dr. H. L. Shantz, mainly during the summers of 1903 and 1904. He made them the basis of a paper,! in which he gives a full descrip- tion of the lakes, together with notes on various features of their fauna and flora. Full determination of the species of entromostraca in the collections were not, however, included in that paper. The collections have since been turned over to the United States National Museum, and at the request of the curator of marine invertebrates I have made determinations of the species. A number of the vials of the lot had dried, but there remained 169 vials of material in good condition, most of which contained entomostraca. These collections are from two groups of lakes, one including nine bodies of water near timber line on the slopes of Pikes Peak, at eleva- tions of 3,110 to 3,626 meters (10,200 to 11,890 feet) above sea level, the other 14 lakes and ponds on the plains, near Colorado Springs, just at the eastern base of Pikes Peak, at elevations of 1,800 to 2,203 meters (5,969 to 7,225 feet). It should also be noted that five of the lakes in the higher group were described by Ward ? in 1904, the paper including a list of 13 species of entromostraca. This paper and the one by Shantz describe the region and the lakes so well that no further notes are needed in the present paper. The collections of Shantz should also be considered in connection with findings of the author in studies of entomostraca from both mountains and plains of Colorado, mainly from collections from the region of Boulder and Tolland, Colorado, about 65 miles north of Pikes Peak.’ Thirty-one species of entomostraca have been identified from the collections of Shantz, distributed as follows: Phyllopoda 1, Cladocera 19, Copepoda 11 species. For a detailed list of the species collected in each lake see Table 1. Three of these species have not previously been reported from Colorado, Diphanosoma brachyurum, Ceriodaphnia 1Shantz, H. L.

The species was described by Marsh from material collected at Walla Walla, Washington, and its occurrence here is a long extension of range for a species of this genus, which is one composed of many species, most of which have rather limited range. It makes up an important part of the fauna of six lakes on the plains, but is not found in any of those in the mountains. There seems to be no doubt about the identification, as it bears all the marks by which Doctor Marsh distinguished it from D. signicauda, and agrees well with his figures and descriptions of material from the State of Washington. The State of Colorado includes an area that has a far greater biological significance than might be expected of a mere political area. Situated as it is, astride the Continental Divide, it includes the highest portion of the Rockies, is the meeting place of eastern and western faunas, includes lowland areas of both the Great Plains and the Great Basin, and in its higher areas includes southern exten- sions of high northern faunas. It is thus a meeting place for faunas which under ordinary conditions are separated by hundreds of miles. The State includes portions of five life zones—Upper Sonoran, Transition, Canadian, Hudsonian, and Arctic-alpine. The collections of Shantz are of interest because they include a section through all of these zones with the very different climatic conditions prevailing at the extremes. It was with these conditions in mind that Shantz selected these lakes for study, as clearly indicated in the opening paragraph of his paper: Here, within a few miles of each other, are two groups of lakes representing quite different types, the alpine and those of the plains. The alpine lakes lie far up on the mountains, * * * with typical alpine surroundings. The plains lakes lie on the western edge of the Great Plains, * * * with condi- tions which are in no wise alpine. They are lowland lakes. The species in these collections take on their greatest significance when considered in connection with the above facts, especially when considered in connection with my own collections from the Tolland region. It is hoped that the frequent reference to my own collections are made in such a way as to emphasize the importance of those made by Shantz, which, though made several years before I had done any collecting, unfortunately, were not determined, and so were deprived of the priority of notice to which they were entitled. Though they do not include by any means as many lakes as do mine, had they been studied soon after they were made they would have antici- pated many of the facts presented in my earlier papers. The species in these collections, just as did those from my own collections, fall into three natural groups, (1) 13 species found on the plains but not extending into the mountains, (2) 9 species found only ArT. 18. ENTOMOSTRACA FROM: COLORADO—DODDS. 3 in the mountains, and (3) 9 species found in both groups of lakes. The third group includes the euthermic species, those which are able to live in both warm and cold water, while the first and second meters BS Slax In Suton id assis no svi x q nu nD ") Diaptomus shoshone ++ ++ Macrothrix montana « » ++ - Latona setifera--- += -+r-- Pleuroxus procurvatus » - - - - Branchinecta coloradensis - - -\[.

These three groups are clearly shown in Figure 1. The significance of these records becomes aa PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, 65. more apparent when we remember that these two groups of lakes are separated by but a few miles, the extremes of the two being separated by not more than 10 miles. Yet the two groups support entomostracan faunas quite distinct from each other, as distinct as if separated by hundreds of miles in a north and south direction, a fact which emphasizes the importance of an altitudinal difference of a little more than a thousand meters. It is commonly recognized that the entomostraca are a group in which dispersal is easy, as indi- cated by the cosmopolitan distribution of some species and the wide range of nearly all genera. Yet here, close together, we find two groups of lakes in each of which there are several species which are not found in the other. The several species common to the two groups stand in strong contrast to the others and serve to emphasize the fact that temperature may be an effective barrier for some species but not for others. The zonal distribution of the species in these collections agrees well with that of the same species as found in the Tolland region. In a few instances the Shantz collections have served to extend the range of species into altitudes in which they had not previously been collected in the Colorado region, and in others they fail to give certain species as wide a range as assigned to them on the basis of collections in various other parts of the State. This, however, is not sur- prising. The gratifying thing is the large extent of the agreement, and the few differences are not surprising in view of the relatively small amount of the work that has been done in this as well as in other parts of the State. It is of interest to remember, also, that the lakes on the plains are artificial, that the oldest was only 28 years old at the time Shantz made his collections, and that most of them are far younger than that, and that even the youngest of them had an abundant entomostracan fauna (as Mesa No. 3, which was only 1 year old and yet yielded eight species). The lakes of the higher group fall into two divisions on the basis of their fauna, and these two divisions have an altitudinal significance. Dead Lake, which falls within the Husdonian or upper part of the Canadian zone, typifies the highest division and agrees well with the 43 lakes and ponds in the Tolland region assigned to the Alpine Zone (Dodds 717). In the 22 vials of material from this lake there were 11 species. By far the most abundant among them were Daphnia pulex and Diaptomus shoshone, the two species which characterize the highest lakes of the Tolland region. Branchinecta coloradensis, another typically alpine form,‘ is also present. Certain 4 Shantz, H. L. Notes on the North American Species of Branchinecta and their Habits, Biol. Bull., vol. 9, pp. 249-264, 1905. Branchinecta coloradensis has been considered an exclusively alpine species, but if the record as deter- mined by the author from a collection sent him from St. Vrain, Colorado, at 1,525 meters (5,000 feet) , May 30, 1912, be correct, our notions on this must be revised. The author invites comment on this and would be glad cf additional material bearing on this point. (See Dodds ’17, p. 77.) ART. 18. ENTOMOSTRACA FROM COLORADO—DODDS. 5 of the other species from this lake have also a significance as belonging to mountain lakes, but none of them are definitely related to the alpine zone as distinct from other mountain elevations. Bald Mountain Lake, 52 meters above timber line, doubtless also belongs to the alpine zone, but its fauna, as represented in the collections, is too scant to be of significance, except for the presence of Daphnia pulex. Michigan Lake, 288 meters below timber line, while at nearly the same elevation as Dead Lake, has a decidedly different fauna, one which relates it to a lower zone in agreement with the 63 lakes of the Tolland region assigned to the Montane (probably Canadian) zone. In this lake are found as the dominant species Daphnia longispina and Diaptomus leptopus, var. piscinae in place of the two species of these genera found in Dead Lake. In two other lakes, Heart and Fish, this is also the case, while in Ribbon Lake these two species are also very abundant with a few individuals of Daphnia pulex in one of the collections. It has been shown clearly in the Tolland region that Diaptomus shoshone belongs to a higher group of lakes than does D. leptopus, var. piscinae, and though no very definite alti- tudinal difference is apparent in the Pike’s Peak group, probably because the number of lakes is few and they are at not greatly differ- ing altitudes, it is quite probable that the same significance attaches to these two species here as in the Tolland region. In making studies of altitudinal zonation it is a striking fact that local condi- tions often change the biotic conditions, so that zonal boundaries are ragged. In the Tolland region, while the two species of Diaptomus did unquestionably belong to two different altitudinal regions, there were a few scattered lakes containing D. shoshone well within the area occupied in the main by D. leptopus. It was also a striking fact in the Tolland region that in mountain lakes where Diaptomus sho- shone was present the species of Daphnia present was pulex, and that when Diaptomus leptomus was present, Daphnia longispina rather than pulex was present. In hardly any instance were both species of Diaptomus found in the same lake nor both species of Daphnia. The collections of Shantz show the same relations to exist in the Pike’s Peak lakes between these four species. They have been selected as ‘‘zone indicators” because when present in a lake they are usually there in considerable numbers and because they appear to give a consistent separation between zones. Other species of significance in the mountain group of lakes, as belonging to mountain rather than to lowland lakes, though not of use in differentiating between the zones within the mountains, are Macrothriz montana (described by Birge from Pike’s Peak material and so far not reported from other localities), Latona setifera, Pleuroxus procurvatus, and Diaptomus nudus, which belong to the colder zones, 6 PROCEEDINGS OF THE NATIONAL MUSEUM. VoL. 65. either in northern latitudes or in higher elevations of more southern regions. The lakes on the plains, as previously mentioned, have several species in common with those in the mountains, but they lack those just mentioned as belonging especially to the mountains. In addition they have several species which do not extend into the mountains at all, but are common forms in lowland lakes. Conspicuous among these are four species of Diaptomus, which, both on account of their size and their numbers, constitute an important part of the entomos- tracan fauna. Diaptomus claviceps and D. washingtonensis are found in abundance in five lakes, while D. siciloides and D. albuquerquensis are plenty in certain others. It would be of interest to have collec- tions from other lakes in this region to determine whether these four species are commonly associated in these two groups, and if possible to determine the underlying conditions. Daphnia pulex is commonly present in these lakes, but D. longispina was not collected, the findings again agreeing with common conditions in the plains portion of the State. The other species do not call for special comment. In regard to amount of entomostracan life, there is some advantage, though not great, with the lakes on the plains. The mountain lakes are by no means scant in species or in individuals, nor is the size of the individuals less than in the warmer lakes. I have made no attempt to compare in detail the fauna of the different lakes. Points of interest might appear in such a study, but it appears that the great- est interest of these collections is their relation to altitudinal zonation and their bearing upon this problem as it has been studied at other points in the same general region.

By Grace ADELBERT SANDHOUSE, of the University of Colorado, Boulder. INTRODUCTION. Since the name Chloralictus was suggested by Robertson in 1902 for certain of the metallic-colored Halictine bees, many interesting new species have been added to this subgenus. The Rocky Mountain States, with their very diverse habitats, have yielded a majority of the species, and still continue to yield many species. Through the efforts of Robertson considerable knowledge of the Chloralicti of Illinois has been given us, and the Chloralictus fauna of the east- central States seems to be quite like that of Illinois. The number of species reported from the Southern States has been remarkably small, a few having been recorded from Florida. In the Pacific States, California has yielded several very interesting species. In the collection of Prof. T. D. A. Cockerell, of the University of Colorado, is a number of Chloralictus—both male and females—from widely separated localities. During the last year the writer has been privileged to work up this collection under the supervision of Pro- fessor Cockerell. The result has been an unusually large number of new species. In very few cases were there representatives of the two sexes from one locality; or, if so represented, the differences between the sexes were so great that it was not considered advisable to at- tempt to match them until further data were obtained. Keys have been compiled for all of the species represented in Professor Cock- erell’s collection as well as the newspecies, but it was not found prac- ticable to include in these key species known only from descriptions.

Legs dark, quite densely pubescent; knees and tarsi red. Habitat.—Boulder, Colorado, May 14 (Irene Bleasdale). Type.—Cat. No, 26402, U.S.N.M. Differs from lazulis Ellis by the darker color; more weakly punc- tured mesothorax; smooth clypeus and supraclypeal area; sculptur- ing of disk of propodeum distinct. Distinguished by the very delicately punctured mesothorax, and the clypeus and supraclypeal area very flat and polished. HALICTUS (CHLORALICTUS) ACTINOSUS, new species. Female.—About 5.5-6 mm, long; golden or brassy green; pu- bescence yellowish white. Facial quadrangle about as long as broad; front and vertex very closely punctured, the punctures becoming more scattered on the sides of the face; supraclypeal area and upper half of clypeus shining golden green with a few coarse punctures; lower half of clypeus black; inner orbits converging below; antennae dark, the flagellum rufo-testaceous beneath. Mesothorax microscop- ically lineolate, very closely punctured; scutellum with deep punc- tures, two small polished spots on the disk; disk of propodeum coarsely granular with rather faint irregular rugae making a reticu- late surface, without an inclosing rim, but polished apically; mes- opleura irregularly punctured; truncation well defined laterally; tegulae very pale testaceous, impunctate.

Ransom, Assistant Custodian, Helminthological Collections, United States National Museum. Looss in 1911 described, as a new species which he named Uncinaria polaris, a hookworm from Vulpes lagopus, North America. In the same paper he redescribed U neinaria criniformis originally re- ported by Goeze in 1782 from the European badger (Meles tarus). Furthermore, he concluded that Uncinaria stenocephala (Railliet) whose type host is the dog in Europe is identical with U. criniformis. The specimens (at least 12 in number) from which U. polaris was described were sent to Looss by Stiles many years previously (Looss, 1911, p. 194). The original material, Looss states (p. 218), bore the number 3250 and came from the Zoological Gardens, Washington, D. GC. The number 3250 evidently refers to a catalogue number of the Helminthological Collection of the United States National Museum, inasmuch as there are in these collections at the present time, labeled with this number, numerous specimens of hookworms which according to the label were collected from Vulpes lagopus at Washington, D. C., by Hassall, August, 1901. These specimens so far as I have examined them are all of one species and correspond closely to Looss’s description of Uncinaria polaris. Undoubtedly Looss’s specimens came from this lot of material and unquestionably the specimens now in the Museum Collections under the catalogue number 3250 belong to Looss’s species, U neinaria polaris. It does not appear in Looss’s paper whether he actually examined specimens of Uncinaria from dogs before arriving at the conclusion that Uncinaria stenocephala is identical with U. criniformis. Al- though he states in general terms that “ Uncinaria criniformis is common in canine animals in various parts of Europe ” (p. 194) and that it occurs “ in various Canidae and Mustelidae of mid and north- ern Europe” (p. 213), he does not say specifically that he has studied specimens from dogs. On the other hand he refers definitely to Un- cinaria criniformis from Meles taxus (p. 607) in connection with his drawings (figs. 105 and 106) of the mouth-capsule of this species. wee NS MEE hs esl pets ae) See ee eh ee es No. 2533—PROCEEDINGS U. S. NATIONAL Museum, VOL. 65, ART. 20. 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65. dn any case, irrespective of the possibility of the occurrence of the species, which Looss calls U. criniformis, in dogs, there is unques- tionably another species common in European dogs, which Railliet has called Uncinaria stenocephala, that is distinctly different from U. - criniformis of Meles tavus. Furthermore Uncinaria stenocephala in- stead of being the same species as U. criniformis is in reality the same as U. polaris. Not only does Railliet’s description of U. stenocephala in certain important respects (size of worms, maximum length of spicules, and tridigitation of terminal branches of dorsal ray of bursa) agree with what is found in the specimens of Uncinaria po- laris (U.S. N. M., 8250) and differing in these respects from what is found in U. criniformis, but specimens of Uncinaria from dogs in various parts of Europe corresponding to Railliet’s description of Uncinaria stenocephala agree among themselves and with U. polaris and differ from U. criniformis as described by Looss and as shown by several lots of specimens from Afeles tavus. For European speci- mens of U. stenocephala from dogs and U. criniformis from Meles taxus to compare with U. polaris I am indebted to Prof. P. Ciurea, Bucurest, Rumania; Prof. A. Henry, Alfort, France; Prof. J. E. W. Thle, Utrecht, Holland, and Prof. T. Pintner, Vienna, Austria. Readily recognizable differences between the two species involved, Uncinaria criniformis and U. stenocephala, including its synonym, U. polaris, are shown in the following brief descriptions. The descrip- tions are not intended to be complete but refer specially to characters that seem useful for diagnostic purposes. UNCINARIA CRINIFORMIS (Goeze, 1782). Specifie diagnosis —Uncinaria: Male about 5.5 (5.3 to 5.9) mm., female about 7.5 (6.8 to 8.2) mm. long. The ventral wall of the mouth capsule when viewed in optical section from the side is only shghtly curved as a rule (fig. 9). The boundary line between the thicker ventral portion and the thinner dorsal portion of the mouth capsule wall (side view) turns forward along the ventral side of the cord of tissue which terminates in the lateral cephalic papilla, and meets the anterior border of the mouth capsule almost at right angles (fig. 9,7). Esophagus of male about 0.55 mm. long, of female about 0.6 mm. long. Lateral lobes of male bursa only a little more than semicircular in shape. Medio-lateral ray slightly thicker than the postero-lateral ray and much thicker than the externo-lateral ray (fig. 10). Dorsal ray bifurcated distally, each branch bidigitate (fig. 11). Spicules 0.46 to 0.63 mm. long with rounded membranous tips. Tail of female 125 to 135 » long; tip of tail into which the caudal bristle is inserted almost ogival in outline (fig. 12). Vulva 4.5 to 5.5 mm. from anterior end of body. ART. 20. HOOKWORMS OF THE GENUS UNCINARIA—RANSOM. 3 Parasitic in intestine of Meles tawus in Europe. Not certainly known as yet to occur in other animals. UNCINARIA STENOCEPHALA (Railliet, 1884). Synonym.—Uneinaria polaris Looss, 1911. Specific diagnosis —Uncinaria: Male about 7 (5.6 to 8.5) mm., female about 10 (7.7 to 12) mm. long. The ventral wall of the mouth capsule when viewed in optical section from the side is con- siderably curved as a rule (figs. 1, 5). The boundary line between the thicker ventral portion and the thinner dorsal portion of the mouth capsule wall (side view) anteriorly continues to curve toward the dorsum and meets the anterior border of the mouth capsule obliquely after crossing the cord of tissue which terminates in the lateral cephalic papilla (figs. 1, 5, ~). Esophagus of male about 075 mm., of female about 0.85 mm. long. Lateral lobes of male bursa rather long, considerably more semi-oval than semicircular in shape. Medio-lateral ray of about the same width as the externo- lateral ray and the postero-lateral ray (figs. 2,6). Dorsal ray bifur- cated distally, each branch tridigitate (figs. 3, 7). Spicules 0.64 to 0.76 mm. long with sharply pointed tips. Tail of female 150 to 290 u long; tip of tail, into which the caudal bristle is inserted, bluntly rounded (figs. 4,8). Vulva 5 to 7.5 mm. from anterior end of body. Parasitic in the intestine of the dog in Europe (type host and type locality). Common in fur foxes in Northern North America. Has also been found in the dog in Alaska (Hadwen) and in the hog (in stomach) at Ottawa, Canada (Hadwen). REMARKS. A lateral view of the head is usually more readily secured in mounted specimens of U. criniformis and U. stenocephala and in my experience is more useful for diagnostic purposes than a dorsal view. Dorsal views give very variable pictures because of differences in the tilting of the head in different specimens, and comparisons of speci- mens and of drawings are more difficult than in the case of lateral views. It may be noted as of interest that Railliet’s drawing of the dorsal view of the head of Uncinaria stenocephala (see Railliet, 1893a, fig. 381) corresponds very well with the appearance frequently shown by specimens of U. polaris (U. S. N. M., 3250) which happen to be less tilted than in the view pictured by Looss (1911, fig. 108). Looss (1911, p. 213) states that the boundary line between the thicker ventral portion and the thinner dorsal portion of the mouth- capsule wall of U. polaris is nearly straight and he shows it but very slightly curved in his drawing (Looss, 1911, fig. 107). In full lateral views of the mouth-capsule of U. polaris (= U. stenocephala) from the fox (fig. 1, 7), and of U. stenocephala from the dog (fig. 5, a) I have found it more curved than Looss has described and figured it. 4 PROCEEDINGS OF THE NATIONAL MUSEUM. Vou. 65. In Looss’s drawing (Looss, 1911, fig. 116) of the bursa of U. erini- jormis the postero-lateral ray is shown as thicker than the medio- lateral ray. In all the specimens I have examined the reverse is true (fig. 10). The lateral membranous ala of the spicule is more strongly de- veloped in U. criniformis than in JU, stenocephala and extends around the tip. In UW. stenocephala it narrows down and disappears before the tip of the spicule is reached. In the specimens that I have examined, the cuticle of Uncinaria stenocephala is usually considerably thicker than that of U. crini- formis. For example, on the tail of the female of the latter species it has not been found to exceed 5 yp in thickness, but commonly measures 7 or 8 » in thickness in the same region of the female of U. stenocephala. In both UY. ecriniformis and U. stenocephala the excretory pore, nerve ring and cervical papillae are located in the same general region of the neck, but vary more or less in their relative positions in different specimens in both species. I have failed to find constant differences in these characters between the two species. The caudal pores on the tail of the female are about 45 » from the tip (excluding the caudal bristle) in U. stenocephala, and in the only case measured in U. criniformis were 30 yw from the tip. It is of interest to note that as yet Uncinaria stenocephala is not known to have become established as a parasite of the dog in the United States except in Alaska. On the other hand it is a common parasite of the foxes on fur farms in the Northern United States, including Alaska and in Canada, and is one of the most serious pests with which fox raisers have to contend. Thus far, the only cases of this parasite in dogs in North America of which I have knowledge are those seen by Hadwen in Alaska. The same observer has found U. stenocephala in a hog at Ottawa, Canada (Ransom, 1921, p. 190). ADDENDUM. While the present paper was in the hands of the printer two papers, one by Fiilleborn (1924) and one by Cameron (1924) have appeared which bear upon the question of the identity of Uncinaria polaris and U. stenocephala. Both authors are of the opinion that the two forms belong to the same species, an opinion which accords with my own findings based upon a study of the material from which Looss obtained his specimens of U. polaris. Cameron appears to be doubtful whether the form described by Goeze as Ascaris criniformis should be considered an identifiable species. In view of the fact, however, that a well-defined species of Uncinaria occurs in the European badger which seems in all probability to be the same as that described by Goeze there appears to be no good reason i oO ic adil Ml ta ‘el pe ae hainateiees oem Cake ae ota, «oe a eh wroioyent da the free etate: Reet aad eer dork, Maya ye ration, Ey Oars, vel 4. pr EHS = Baits ua ahs eee ers: j Les ye cot & re 43 aa, 7 \ AER raseptlioat anh Peg t eo? tented by \? 1 uae, terrier: send i ; ; LY Haein . j ' prea, ¢ a nascbl ij » on : : Ns.

Abdomen narrow and tapering, the apex curved downward; the first and second segments pale yellow above except at the sides, the following three wholly black, the sides of all but the first with long, silky, whitish hairs, the second also bears black spiny hairs at the side. Venter membraneous, whitish. Legs mostly yellowish, but the hind femora and tibiae and the apices of all the tarsi are black or blackish, and the front femora and tibiae are slightly infuscated. The front femora are thickened, and have long pale hair below; the front tibiae have a heavy fringe of brownish hair on the outer hind side, which extends on the first and second tarsal joints. The hind femora are large, greatly thick- ened and curved; their tibiae are rather stout and have on the outer front side numerous long curled pale hairs extending forward, over- lapping the femora in the flexed position.

Oxproyn, Of Stanford University, California INTRODUCTION The cut through Nob Hill at San Pedro exposed a large deposit of the Lower San Pedro series of the Pleistocene. In July, 1918, the steam shovel had worked its way down to the bed, uncoveririg no shells of the upper series in the cut, except a few at the south end. This was especially good, as heretofore in most places where the lower series was exposed, the upper series had cropped out above it; as at Deadman’s Island. This made collecting in the latter place from the lower series rather uncertain, as the upper would cave down in quantities from the action of the wind and rain, settle on the edge of the lower, and on becoming packed, looked as if it belonged there. This immense deposit, extending the whole length and breadth of the cut and an unknown distance further, was nearly 6 feet thick, and in the center of the cut, where it had not been graded down, was 20 feet below the surface and dipped to the northeast. The first layer commencing at the bottom was about 15 inches thick and sparsely filled with shells, mostly bivalves. Next above there was a bed of bivalves about 4 inches thick, composed mostly of Afacoma nasuta Conrad, and Macoma secta Conrad; these were very plentiful and in a natural condition as they had lived, and had not been disturbed, but were covered up by about 17 inches of sand in which there were no shells. The next layer was about 4 inches thick, composed of Ostrea lurida Carpenter, and Aletes squamigerus Carpenter. While the life of the bed of Afacoma was a short one, as none of them had reached a maximum growth, the bed of oysters had apparently lasted for a much longer period of time. This bed, like that of the Macomas, was not disturbed but covered up in a natural position. The next layer is a conglomerate mass two feet thick, very compact but not hardened; washed up by some storm, it-contains a great many species from deep water. The next and last layer was about 17 inches thick, No. 2535.—PROCEEDINGS U. S. NATIONAL Museum, VOL. 65, ART. 22. 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65 composed of loose washed sand and small drift shells washed high on the beach. Judging from the species that lived here, in the two natural beds mentioned, this place must have been an estuary or flat in a protected place, though exposed to unusually severe storms; a place such as existed at Tims Point 30 or 40 years ago. Of the 242 species of shells found in the Nob Hill cut, 115 are found in Puget Sound and north of there. In our four seasons’: dredging and shore collecting near Friday Harbor, Wash., we have found a great many of them living. Our dredging has been mostly in the San Juan Channel, where I think more of the Nob Hill fossil species are found living, than anywhere else. The water in the channel is very cold, because the current comes in from the ocean through the Strait of Juan de Fuca. The water in Departure Bay about 75 miles north of there will average 10 degrees warmer the year round, according to Doctor Fraser who is in charge of the Do- minion Marine Biological Station. After the Lower San Pedro time and the climate of California began to get warmer, many of the mol- lusks went north or sought the cold waters of a greater depth. There seems to be a streak of the northern mollusks in about 100 fathoms all along the coast as far south as Lower California. It isa fact that there are quite a few southern species in the lower San Pedro, and also some northern species in the upper; they all lived in the lower San Pedro during that epoch. They did not all go north, some accustomed themselves to the change in temperature, and are found living now near San Pedro. Some withstood the change for a long time and are found in the upper series, but finally died out, and are not now found living here except in very deep water. Acknowledgments are due to Dr. Paul Bartsch, of the United States National Museum, and to Dr. W. H. Dall, of the United States Geological survey, for assistance in the identification of some doubt- ful species and general criticism of the manuscript. I am also deeply indebted to Dr. J. P. Smith, of the Department of Geology in Stanford University, for kindly criticism and much help. ‘Types of the new forms are in the Oldroyd Collection or that of the National Museum.

DESCRIPTIONS OF NEW FORMS. ACTEOCINA PEDROENSIS, new species. Plate 2, fig. 9. Shell large, slightly pyriform, with a small prominent subcylin- drical nucleus of about two whorls and five subsequent whorls; suture narrowly channeled; the external surface is decorticated in all the specimens, but appears to have been smooth, the surface remaining shows faint spiral feebly punctate striae with rather wide inter- 94 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65 spaces, all of which sculpture may have been concealed in the perfect shell; aperture slightly shorter than the last whorl; outer lip sharp, very slightly protractively arcuate, receding anteriorly and deeply rounded into the pillar lip, which is thickened and pro- vided with a prominent sharp plait; body with a smooth coat of enamel; length of shell, 20; of last whorl, 18.5; of aperture, 16; maximum diameter, 10 mm. Type.—Cat. No. 352346, U.S.N.M. This is larger than any other species of the coast and is less cylindrical than A. culcitella Gould, the most nearly allied species. A specimen which has lost the nucleus is 23 mm. long and 10.5 mm. in diameter. MARGINELLA JEWETTII NANELLA, new subspecies. Plate 2, fig. 8. Shell much like typical jewetééi but uniformly smaller, more slender proportionately, somewhat less wide at the shoulder, and while jewetti usually has five plaits, including that on the edge of the pillar, this variety when adult often has as many as eight. Relative dimensions are: M. jewettii; length, 5.5; maximum diameter, 4.5 mm. M. nanella; length, 5.0; maximum diameter, 3.7.mm. Type.—Cat. No. 352361, U.S.N.M. Many M. jewettii are larger than the average specimen above cited, but the size of specimens of the fossil variety is suprisingly uniform. Many specimens of the latter have been examined. ALIA TUBEROSA MAJOR, new subspecies. Plate 2, fig. 11. Shell lke the typical recent form, with the same number of whorls but uniformly much larger. Comparative measurements for specimens of eight whorls are: A. tuberosa; length, 8; maximum diameter, 3.8 mm. Var. major; length, 11; maximum diameter, 5.0 mm. Type.—Cat. No. 352369, U.S.N.M. TURBONILLA (STRIOTURBONILLA) PECORA, new species. Plate 1, fig. 6. Shell of medium size, elongate turrited, yellowish white. Nuclear whorls two and a half, forming a somewhat depressed helicoid spire, the axis of which is at right angles to that of the succeeding turns, in the first of which the tilted edge of the last whorl is one-fifth im- mersed. Postnuclear whorls almost flattened, almost tabulately shouldered at the summit, marked by strong, decidedly protractively ART. 22 SAN PEDRO FAUNA—OLDROYD. 25 slanting axial ribs, of which 14 occur upon the first, second, and third, 16 upon the fourth, fifth, and sixth, 18 upon the seventh to eleventh, and 22 upon the penultimate turn. These ribs extend quite prominently to the summit of the whorls, which they render slightly crenulated. The intercostal spaces are about as wide as the ribs, terminating a little posterior to the suture, which leaves a narrow, smooth band immediately above the well-constricted suture. Pe- riphery of the last whorl well rounded. Base short, well rounded, marked by the feeble continuations of the axial ribs, which evanesce shortly after passing the periphery. The entire surface of the shell is marked by fine, closely spaced spiral striations. Aperture broadly oval; posterior angle obtuse; outer lip thin; inner lip slightly curved, reflected over and appressed to the base for its anterior third, and provided with an obsolete fold a little anterior to its insertion. Type.—Cat. No. 333506, U.S.N.M., has 12.5 whorls and measures: length, 8.2 mm.; diameter, 2 mm. Cat. No. 352503 U.S.N.M. con- tains another specimen showing the nucleus. Three additional specimens are in the Oldroyd collection. The present species belongs to the group of Turbonilla (Striotur- bonilla) dinora, panamensis, schmitti, and button. It is less robust than 7’. (S.) dinora and has more ribs than that species, and is more robust than any of the other members of the group. The fine spiral striations have been omitted in the figure. TURBONILLA (PYRGOLAMPROS) COLLISELLA, new species. Plate 1, fig. 11. Shell moderately large, elongate conic, yellowish, with a brownish suffusion which probably indicates that when living it was brown. Nuclear whorls two and a fifth, forming a somewhat depressed heli- coid spiral, the axis of which is almost at right angles to that of the succeeding turns, in the first of which the tilted edge of the nuclear spiral is about one-fifth immersed. Early postnuclear whorls moder- ately rounded, the later ones almost flattened, slightly shouldered at the summit, marked by almost vertical axial ribs. Of these ribs, which are much less strong and more numerous and more closely spaced on the early whorls than on the later, where they become senescent on the last turn, 24 occur on the second, 30 upon the third, 26 upon the fourth, 24 upon the fifth and sixth, 21 upon the seventh, eighth, and ninth, 28 upon the tenth, while on the last whorl they are decidedly irregular and irregularly spaced. The intercostal spaces vary in width, being very narrow on the early turns, moder- ately wide on the median and again on the later very narrow. Suture moderately constricted. Periphery of the last whorl well roundea, Base short, marked by the feeble continuations of the axial ribs, 26 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65 which extend to the umbilical chink. Aperture rather large, broadly oval; posterior angle obtuse; outer lip thin; inner lip slightly curved and reflected, with the posterior third reflected over and appressed to the base. There is an oblique feeble fold on the columella a little anterior to its insertion. Type.—Cat. No. 333507, U.S.N.M., has lost the nucleus and first two postnuclear turns. The 9.5 whorls remaining measure: Length, 12 mm.; diameter, 3.3 mm. The nucleus and the first two postnuclear turns were described from a young specimen, Cat. No. 352507, U.S.N.M., having nine post- nuclear whorls, which measures: Length, 7.1 mm.; diameter, 2.2 mm. Twenty-seven additional specimens are in the Oldroyd collection. This species belongs near 7'urbonilla (Pyrgolampros) hannibali, Bartsch. TURBONILLA (PYRGOLAMPROS) IDAE, new species. Plate 1, fig. 9. Shell of medium size, elongate conic, pale brown. Nuclear whorls two and a half, forming a very small, slightly elevated heli- coid spiral, the axis of which is at right angles to that of the suc- ceeding turns, in the first of which the tilted edge of the nuclear spiral is about one-fourth immersed. The first two or three post- nuclear whorls well rounded, the succeeding turns almost flattened, or sometimes evenly slightly concave. All the whorls very nar- rowly shouldered at the summit. The first postnuclear whorl smooth, the second one showing mere indications of axial riblets, while on the succeeding turns they become increasingly stronger, well rounded, and somewhat protractively slanting. Of these riblets, 20 occur upon the third, 18 upon the fourth to sixth, 20 upon the seventh, 22 upon the eighth, 24 upon the ninth, and 34 upon the last turn. On this they become less conspicuous. Intercostal spaces mere lines on the first turns, while on the median whorls they are about half as wide as the axial ribs, and on the last turn they are again materially reduced. Suture slightly constricted. Periphery of the last whorl somewhat inflated, well rounded. Base short, somewhat inflated, well rounded, marked by the feeble continuations of the axial riblets, which extend to the umbilical chink. The entire surface of the spire and base crossed by numerous, closely spaced spiral striations. Aperture broadly oval; posterior angle acute; outer lip thin; inner lip curved, rather strongly reflected, almost free throughout its entire length, posteriorly covering the greater portion of the umbilical chink. A feeble twist is present on the columella at its insertion. ART. 22 SAN PEDRO FAUNA—OLDROYD. 27 Type.—Cat No. 333509, U.S.N.M., has lost the nucleus and the first nuclear turn. The nine remaining measure: Length, 7.9 mm.; diameter, 2.8 mm. The nuclear turns were described from a young specimen, Cat. No. 352508, U.S.N.M.; 38 additional specimens are entered as Cat. No. 352533, U.S.N.M.; 150 are in the Oldroyd collection. This specimen is related to Turbonilla (Pyrgolampros) taylori, Dall and Bartsch, but is much smaller than that species, and has more ribs. The fine spiral striations have been omitted in the figure. TURBONILLA (PYRGISCUS) HIMERTA, new species. Plate 1, fig. 1. Shell moderately large, pale yellow. Nuclear whorls two and a half, well rounded, forming a decidedly repressed helicoid spiral, the axis of which is almost at right angles to that of the succeeding turns, in the first of which the tilted edge of the nuclear spiral is about one-fourth immersed. Postnuclear whorls narrowly shoul- dered at the summit, almost flattened in the middle, marked by 20 weak, slightly retractively curved, axial ribs on the first turn. On the second turn and the succeeding turns there are strong axial ribs, which have a protractive slant. Of these ribs, 18 occur upon the second to fifth, 20 upon the sixth, 24 upon the seventh, where they begin to have a slight retractive curve, while on the last turn there are 38, which have a decided retractive curve. The spaces separating these ribs are narrow on the first turn, about as wide as the ribs on the succeeding two, and a little wider than the ribs on the next two, while on the last they are a little narrower than the ribs. The spiral sculpture consists of a series of incised lines and pits. The widest pits are the line at the periphery, where the diameter equals the height. Another series of pits is about half the width of the peripheral, and occupies a space halfway between the summit and the periphery, while a third series of about equal width occupies the space a little nearer to the peripheral than the median line of pits. The two series of pits posterior to the median pits follow next in strength and are equal. In addition to this, there are incised spiral lines, of which the first is about half as far removed from the summit as it is from its neighbor anteriorly, the space between the first and second being equal to about one-sixth of the width between the summit and the periphery. The second, third, and fourth incised lines are equal and rather closely spaced. These are followed by the two medium-sized pits already referred to, posterior to the median pits, then by the median pits. The space between the median pit and the medium-sized pit anterior to it is crossed by two incised spiral lines, of which the first is a little 28 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL, 65 farther removed from the median pit than from its neighbor, while the second is closely approximated .to the second pit. The space between the medium-sized pit and the peripheral pit is crossed by two lines, of which the first divides the space between the two, while the last is separated from the peripheral pit by a mere hair line. Periphery of the last whorl well rounded. Base marked by the feeble continuations of the axial ribs, which evanesce before reach- ing the umbilical chink, and 18 incised spiral lines of varying strength and spacing. Suture moderately constricted. Aperture broadly ovate; posterior angle acute; outer lip thin; inner lip con- cave, reflected over and appressed for half its length to the preceding turn, bearing a weak fold a little anterior to its insertion. Type.—Cat. No. 333508, U.S.N.M., has lost the nucleus. The 8.75 whorls remaining measure: 6.4 mm.; diameter, 2 mm. The nuclear whorls were described from specimen, Cat. No. 352509 U.S.N.M. Three additional specimens are in the Oldroyd collection. This species belongs to the group of Yurbonilla (Pyrgiscus) auricoma Dall and Bartsch and 7. (P.) castanea Keep. TURBONILLA (MORMULA) EPIPHANEA, new species. Plate ano aioe Shell very large. (Nuclear whorls decollated in all the specimens seen.) Postnuclear whorls almost appressed at the summit, well rounded, marked by rather strong, almost vertical axial ribs, of which 14 occur upon the first of the remaining turns, 16 upon the second, 18 upon the third and fourth, 20 upon the fifth to seventh, 22 upon the eighth to tenth, 24 upon the eleventh, while on the succeeding turns they become enfeebled and finally obsolete. In addition to the axial ribs, low rounded varices, the result of the fusion of several ribs, occur at regular intervals. Intercostal spaces about twice as wide as the ribs, crossed by 8 almost equal, incised spiral lines, which, however, do not enclose equal spaces. The space between the first and second, second and third and sixth and seventh is about twice as wide as the space between the summit and the first, and those between the third and fourth and fourth and fifth, while the space between the fifth and sixth and seventh and eighth stand halfway between these in width. In addition to this, there are very finely incised lines in the spaces between the coarse incised lines. On the last turn, where the axial sculpture becomes obsolete, the spiral sculpture is also very irregular and many more incised lines are apparent. Periphery of the last whorl well rounded. Base short, well rounded, marked by the feeble continuations of the irregular axial ribs, which form mere threads, and in that fashion extend to the umbilical chink, and numerous closely spaced spiral striations. ART. 22 SAN PEDRO FAUNA—OLDROYD. 29 Aperture subquadrate; posterior angle obtuse; outer lip’ thin, bearing three spiral lirae within; inner lip somewhat twisted, almost vertical, its edge reflected and appressed to the preceding whorl for one-third of its length. Type—Cat. No. 333510, U.S.N.M., has 14.5 whorls and measures: Length, 20.8 mm.; diameter, 4.9 mm. Five additional specimens, Cat. No. 352510, U.S.N.M., are also in the National Museum collection, and 20 are in the Oldroyd collection. This species is related to Zurbonilla (Mormula) tridentata Car- penter, but is much larger than that species. ODOSTOMIA (IVARA) AMAYA, new species. Plate 1, fig. 7. Shell elongate ovate, yellowish white. Nuclear whorls deeply 1m- mersed in the first of the postnuclear turns, above which the outer edge of the last whorl only projects. Postnuclear whorls very broadly flatly tabulated at the summit, with a sharp angle at the shoulder of the summit, the portion anterior to the shoulder moderately well rounded and crossed by feeble, almost vertical, axial ribs, of which 32 occur upon the third, while upon the last whorl they become decidedly irregular in strength and spacing. On the third whorl the spaces that separate the ribs are almost as wide as the ribs. In addition to the axial sculpture, the whorls are marked by spiral striations, which cause the spaces between them to appear as raised flattened cords. These are poorly defined on the first two turns in the type, while on the third there are eight between the summit and the suture and nine on the last whorl. Periphery of the last whorl well rounded. Base rather long, well rounded, marked by the feeble continuations of the axial ribs, and eight incised spiral] lines, the combinations of the two forming a sculpture correspond- ing with that on the spire. Aperture elongate ovate; posterior angle rendered decidedly obtuse by the tabulated summit; outer lip thin; inner lip strongly curved, with a conspicuous fold at its insertion; parietal wall covered by a thin callus. Type.—Cat. No. 352514, U.S.N.M., has 4.5 postnuclear whorls and measures: length, 3.8 mm.; diameter, 1.8 mm. Compared with Odostomia (Ivara) turricula Dall and Bartsch, the present species is differentiated by its much more robust form and coarser sculpture. ODOSTOMIA (CHRYSALLIDA) GOMPHINA, new species. Plate 1, fig. 3. Shell very elongate ovate, yellowish white. Nuclear whorls deeply, obliquely immersed in the first of the succeeding turns, above whick only the tilted edge of the last volution projects, which appears well 30 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 65 rounded and smooth. Postnuclear whorls well rounded, narrowly shouldered at the summit, marked by strong, decidedly retractively slanting axial ribs, of which 18 occur upon the first, 20 upon the second, 22 upon the third, and 26 upon the last turn. In addition to the axial ribs, the whorls are crossed by 4 equal and equally spaced spiral cords, which are about as wide as the spaces that separate them. The first of these is at the summit. The intersection of the axial ribs and spiral cords forms strong, rounded tubercles which have their long axes, which are only slightly greater than the shorter, parallel with the spiral sculpture. Periphery of the last whorl marked by a spiral cord, which falls partly in the suture on the last two turns. Suture not channeled. Base moderately long, well rounded, with a narrow umbilical chink, marked by 10 spiral cords, which become suc- cessively narrower and closer spaced from the periphery to the um- bilical chink. Aperture ovate; posterior angle acute; outer lip thin; inner lip strongly curved and decidedly reflected and appressed to the base, provided with a rather strong fold at the insertion of the colum- ella; parietal wall covered with a rather thick callus, which alone renders the peritreme complete. Type—Cat. No. 352515, U.S.N.M., has 5 postnuclear whorls and measures: Length, 3.2 mm.; diameter, 1.4 mm. The present species is related to the recent group of which Odostomia (Chrysallida) benthina and O. (C.) promeces are mem- bers. An additional specimen is in the Oldroyd collection. ODOSTOMIA (CHRYSALLIDA) SCELERA, new species. Plate 1, fig. 4. Shell elongate conic, yellowish white. Nuclear whorls small, deeply, obliquely immersed in the first of the postnuclear turns, above which the tilted edge of the last volution only projects. Post- nuclear whorls strongly shouldered at the summit, marked by very strong, retractively slanting axial ribs, of which 14 occur upon the second and third, 16 upon the fourth, and 20 upon the last turn. In addition to the axial ribs, the whorls are marked by 4 strong spiral cords, which are not quite equal to the axial ribs in strength, and which render the junction with the axial ribs strongly nodulose, the nodules being a little longer than wide. The spaces inclosed between the axial ribs and spiral cords are rectangular pits. Periphery of the last whorl marked by a strong cord, separated from the last cord on the spire by a channel as wide as that separating the other cords of the spire, and crossed by the continuations of the axial ribs which terminate at the posterior border of the peripheral cord. Suture strongly channeled. “Base feebly rounded, marked by four spiral ART. 22 SAN PEDRO FAUNA—OLDROYD. 31 cords, which are successively closer spaced and weaker from the posterior anteriorly, the fourth being really a broad, tumid area, surrounding the umbilical chink. The broad channels separating these cords are crossed by numerous slender axial threads. Aperture oval; posterior angle acute; outer lip thin at the edge, thick within; inner lip curved, reflected over and appressed to the preceding turn, provided with a strong, oblique fold at its insertion; parietal wall covered by a thick callus. Type.——Cat. No. 352516, U.S.N.M., has 5 whorls and measures: Length, 3.2 mm.; diameter, 1.5 mm. This is most nearly related to Odostomia (Chrysallida) hetero- cincta Bartsch, from which it is at once distinguished by its more robust size and less acutely tuberculated sculpture. Cat. No. 352517, U.S.N.M., contains 2 more specimens from the type locality, and 6 additional specimens are in the Oldroyd col- lection. ODOSTOMIA (EVALEA) TERSA, new species. Plate 1, fig. 10. Shell elongate conic, yellowish white. Nuclear whorls deeply, obliquely immersed in the first of the postnuclear whorls, above which only the tilted edge of the last volution projects.

Suture slightiy con- stricted. Periphery of the last whorl well rounded. Base slightly inflated, rather long, narrowly umbilicated, marked like the spire. Aperture long, oval; posterior angle acute; outer lip thin at the edge, thick within; inner lip oblique, slightly sinuous, provided with a strong fold opposite the umbilical chink; parietal wall covered by a moderately thick callus. Type.—Cat. No. 352518, U.S.N.M., has 5 postnuclear whorls re- maining, having lost probably the first half of the postnuclear turn, and measures: Length, 5 mm.; diameter, 2 mm. Cat. No. 352519, U.S.N.M., contains 2 specimens from the type locality, one of which served for description of the nucleus. Four additional specimens are in the Oldroyd collection. The present species recalls Odostomia (E'valea) valdezi Dall and Bartsch, but is more than double the size of that species in every way. The fine spiral striations have been omitted in the figure.

Type.—Cat. No. 352520, U.S.N.M., has 6.5 postnuclear whorls and measures: Length, 5.6 mm.; diameter, 2.4 mm. An additional specimen is in the Oldroyd collection. This species suggests Odostomia (Evalea) youngi Dall and Bartsch, but is distinguished from this at once by its more broadly conic outline. ODOSTOMIA (EVALEA) MANCA, new species. Plate 1, fig. 5. Shell very elongate ovate, yellowish white. Nuclear whorls small, deeply, obliquely immersed in the first of the postnuclear whorls, above which only the tilted edge of the last volution projects.

No. 352524, U.S.N.M., contains 5 additional specimens from the type locality, and there are 10 in the Oldroyd collection. This species, while it belongs to the coarsely sculptured group of Evalea, does not seem to be very closely related to any of the de- scribed forms. ODOSTOMIA (EVALEA) FITELLA, new species. Plate 1, fig. 8. Shell very regularly elongate conic, yellowish white.

By A. L. TreapweEL, Of the Department of Zoology, Vassar College, Poughkeepsie, New York. Among other material collected by Dr. F. Felippone, at Punta Arenas, Chile, during the past year was found a single, incomplete annelid, which was submitted to me for examination by the United States National Museum. I have been unable to find this described in any literature at my disposal and am recording it here as a new species, though because of the imperfect condition of the specimen the specific description must be incomplete. It has been included under Lagisca, because of the form of the prostomium, the fact that the neuropodial setae are smaller than the notopodial and have transverse denticulations, and on the assumption that only a small portion of the posterior end is missing. LAGISCA CRASSA, new species. The prostomium (fig. 1) is much broader than long, and is divided anteriorly by a deep V-shaped incision which extends half way of the length of the prostomium. From its posterior angle a slight dorsal depression continues posteriorly for the remainder of the prosto- mium. The result of this structure is that the prostomium is divided into halves, each roughly ovate in outline with its outer margin decidedly rounded toward its posterior end. From the point of greatest width the lateral margins slope gradually toward the anterior end where they meet with the inner margins which form the edges of the V. These two margins meet at a blunt angle but do not form a decided “ peak.” The eyes are all of approxi- mately the same size, the posterior pair situated near the dorsal mid-line of the corresponding half of the prostomium a little posterior to its center. ‘The anterior eyes are a very little farther apart than the posterior, and situated near the anterior margins. The median tentacle has a stout cirrophore which completely fills the above-mentioned V in the prostomium, and is about as long as the prostomium. The terminal joint is about as long as the cirro- No. 2536—PRocEeDINGS U. S.

The lateral tentacles are much shorter and more slender than the median, but have ap- proximately the same form. The palps are six to eight times as long as the prostomium and rather heavy. In the specimen they are very much wrinkled, a condition probably a result of the preserva- tion. The tentacular cirri are like the tentacles in form but are | 3 ZF 77ZLFF FIEIV IF eay eo LAGISCA CRASSA, NEW SPECIES.

All tentacles and cirri are colorless at the apex, an appearance which in some is heightened by a sub- apical pigment band. The contrast between the pigment band and the colorless apex sometimes makes them look as if the apex were slightly swollen, but this is evidently merely an optical effect. Ex- cept for this colorless apex, the cirri around the prostomium and the palps show traces of a brown color. A similar color appears on art. 23. A NEW MARINE ANNELID FROM CHILE—TREADWELL. 3 the dorsal cirri, and a poorly defined band of brown pigment extends along the mid-dorsal line of the body broken only by a prominent white patch in each somite near the dorsal anterior margin. This coloration is more sharply marked toward the posterior end of the fragment. On the dorsal surface of somites which do not carry cirro- phores is a rounded lobe lying in line with the cirrophores of other somites (fig. 2) and toward the posterior part of the specimen these knobs show the same brown color. The protruded proboscis is about twice as long as the palps and has at the apex, above and below, nine prominent conical marginal lobes. Most of the elytra are lost, but they evidently did not cover the dorsal surface when in place. They are roughly circular in outline, are more or less mottled with brown and under low power, because of the distribution of this pigment, look as if the margins were thicker than the center. This is apparently merely an effect produced by the pigment. The elytron is thickly studded over its surface with short sharp conical spines which extend to the margins and some- times protrude beyond this. The neuropodium (fig. 2), has an obliquely truncated setal lobe, with the upper outer angle prolonged into a conical “tongue” into which the apex of the acicula extends. Aside from this terminal protrusion the neuropodium is cylindrical, showing no narrowing up to the point where the truncation begins. The neural setae are smaller than the notal and are golden yellow in color. Each has (fig. 3) transversely arranged plates whose free margins are dentic- ulated. These plates are longer than the width of the seta so that seen in full face they extend on both sides of the shaft. In profile they have the appearance shown in the figure. The notopodial lobe of the parapodium is rounded in form and is shorter than the neuro- podial but has a similar apical “ tongue” into which the acicula ex- tends. The notopodial setae are chestnut-brown in color and are larger than the neuropodial. Each seta (fig. 4) has transverse rows of spines the row nearest the apex being the shortest and from here there is a gradual increase in length so that the longest are more than half as long as the diameter of the seta.

By Eart V. SHANNON, Assistant Curator, Department of Geology, United States National Museum. INTRODUCTION. The present description pertains to a mineral from near Round Mountain, Nye County, Nev., which occurs in a quartz vein with molybdenite, mica, and minor amounts of other minerals. Upon analysis this has been found to be an argentiferous sulphobismuthite of lead and copper differing in ratios from any known mineral. For this new mineral the name proposed is benjaminite, in honor of Dr. Marcus Benjamin of the United States National Museum. The specimens first examined were sent to the United States Geological Survey some years ago, where they were incorporated in a series of bismuth ores by Frank L. Hess and forwarded to the National Museum. It was not known who sent them in and the only information regarding them was contained in a label reading “Aikinite Mining Co., Round Mountain, Nevada.” It was con- cluded from the name of the mining company that the mineral had been identified as aikinite and that it was a characteristic mineral of the deposit. Nothing further could be learned about the mineral or the mine, however, until an inquiry was addressed to H. G. Clinton, of Manhattan, Nev. Fortunately Mr. Clinton was familiar with the mine, its geology, history, and mineralogy, and was able to visit the locality and to supply an additional very fine specimen of the benja- minite, especially welcome since the original small lot had been almost entirely used up in the several analyses, as well as specimens of the associated minerals. It developed from this correspondence that the material originally received at the Geological Survey had also come from Mr. Clinton. The writer takes this opportunity to acknowledge his obligation to Mr. Clinton for his generosity and his thorough knowledge of the region. The following is quoted from his letter: The Aikinite Mining Co. has been out of existence for years but they were operating the Outlaw Mine some 12 miles north of here [Manhattan] at the head of Mariposa Canyon. The mineral [benjaminite] occurs in large and small bunches and blotches in a dense white quartz, near the southern contact of a rock locally called pegmatite, but described by J. M. Hill as a soda-granite, and an intrusive rhyolite. I have No. 2537—PROCEEDINGS U. S. NATIONAL MUSEUM, VOL. 65, ART. 24. 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 had assays of 300 ounces in silver from the mineral. I have also noted large flakes of molybdenite associated with it, but all that was ever mined has been carried away. I note that you have only a few fragments of the mineral left so I am sending my specimen, which is the finest I have yet seen. I hope to get more. I am sending also all the other minerals associated with it, including three or four colors of material that leach out of the ledge, also a small piece of the soda granite. Close to this Outlaw tunnel is a deposit of cinnabar with values in free gold. Three miles east on the same contact is another bismuth-silver deposit, the bismuth here being in the form of carbonate. Three miles west is a deposit of the molybdenite like the sample sent. ASSOCIATED MINERALS. The minerals occurring in the specimens with the benjaminite are quartz, chalcopyrite, pyrite, covellite, muscovite, molybdenite, and fluorite. The quartz is coarsely crystalline white vein quartz which forms the gangue of the other minerals.

Some of the largest of these contain bubbles and the smaller are aligned into strings. A later introduction of quartz took place filling numerous very fine fractures in the older quartz, and especially in the sulphides. These later quartz seams are especially conspicuous in polished surfaces of the sulphides under the microscope and are indicated in the drawing (fig. 2). Muscovite is common in the quartz as scales and aggregates of scales. The individual crystals range up to 1 cm. in diameter and are in part hexagonal in outline. In color the mica varies from pale ART. 24 BENJAMINITE, A NEW MINERAIL--SHANNON a green to white or pale brown and much of it has a more or less pearly luster. It is probably all of the margarodite variety of muscovite, low in potash and correspondingly high in basic hydrogen. Opti- cally it is negative with the acute bisectrix perpendicular to the plates, 2E estimated at 60° to 70°, a=1.562, 8= 1.597, y= 1.602, r>v weak. Other specimens from the mine consist entirely of masses of scales of mica, some of which contain scattered crystals of fluorite an rare masses of benjaminite. Pyrite occurs as cubic crystals which are rare in intimate associa- tion with the benjaminite. Other quartz specimens which contain no benjaminite show cubic crystals up to 3 cm. in diameter isolated in the quartz which also contains mica. The pyrite crystals are greatly shattered and show dis- ASS tinct cubic cleavage. hi \ ne Molybdenite occurs as a graph- lf, \ SS itic slickensided smear on frac- Lf i ALY \ tures and also as foliated scales Be and small rosettes of scales. It is occasionally interleaved with mica. Some of the rosettes reach a diameter of 5mm. Occasion- ally these have a sharp hexagonal outline and are made up of six triangular sectors with a twinning lme down the center and stria- tion on either side like the A structure of mica. As seen in polished sections the molybde- me Quartz Benjaminite nite is older than the benjamin- ite and its folia have been con- torted, separated, and bent by the later fractures, although the OMT nn yr Molybdenite Chaleo pyrite Wy yl, Fic 3.—SKETCH OF POLISHED SURFACE SHOW- ING RELATIONS OF BENJAMINITE, MOLYB- z DENITE, CHALCOPYRITE AND QUARTZ. cracks do not cross the folia but pass around their ends. The relations of the molybdenite to the other minerals are shown in the drawings (figs. 2 and 3). Fluorite occurs especially as isolated crystals in the granular masses of mica where it forms crystals up to 4 cm. in maximum size. The color varies from deep purple to purplish red, yellow and colorless. In the mica fluorite occurred in the same specimen with benjaminite but only one specimen shows fluorite in quartz and this does not contain any benjaminite. The fluorite forms a skeleton cube apparently developing by metasomatic replacement of the quartz. Chalcopyrite occurs only as minute, almost microscopic, grains and was introduced with the late quartz which fills fine cracks in 4 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 the benjaminite. It forms grains isolated in the quartz and smal! areas grown on the benjaminite or apparently, in some cases, re- placing the benjaminite. ‘This mineral is mainly clearly later than the benjaminite although a very little may be contemporaneous with it. The relations of the chalcopyrite are shown in figures 1, 2, and 3. Covellite occurs in minute amount as a later replacement, along cracks, of both chalcopyrite and benjaminite, preferring the latter. The field showing the greatest amount of this mineral is that shown in Figure 1. The amount of covellite present in the analyzed ma- terial was so exceedingly small that it emus not have any effect on the analytic results. Chalcocite was seen as a few rare and very minute areas replacing covellite. PARAGENESIS. The minerals may be arranged in the following paragenetic order although there is some doubt as to the mutual age relations of some of the earlier ones. 1. Quartz. . Muscovite. . Molybdenite. . Pyrite. . Fluorite. Benjaminite. . Quartz. . Chalcopyrite. . Covellite. . Chalcocite. While a considerable time gap may have intervened between the first five and the second five of these minerals it is most probable that the whole series belongs to a single genetic sequence although the covellite and chalcocite may be products of downward secondary enrichment. The benjaminite, a silver-bismuth ore mineral, is thus a constituent of a vein characterized by mica, molybdenite, and fluorite, minerals typical of high temperature veins of pegmatitic affiliations. Such a silver deposit is more or less unique. SOMDNMQAR WN —_ GENERAL DESCRIPTION OF BENJAMINITE. The benjaminite is the only abundant metallic mineral in the ore and carries the silver for which the mine was explored. It forms irregular masses up to 5 cm. in maximum diameter which have clearly developed along fractures in the quartz, apparently by replace- ment. The benjaminite contains some pyrite although many masses are free from it and it all contains fine grains of chalcopyrite developed along later minute quartz filled cracks. The color on fresh fracture ART, 24 BENJAMINITE, A NEW MINERAL—SHANNON 5 is medium gray and the luster is metallic with a greasy appearance. At first glance the mineral suggets massive tetrahedrite. It has a moderately good cleavage in one direction, somewhat interrupted by the later cracks. The masses are coarse equigranular and the mineral shows no tendency to platy, fibrous or prismatic form. Cleavage surfaces indicate the crystals to reach a maximum size of 15 mm. in the masses. Upon exposure the cleavage surface remains bright or becomes slightly yellow while in another direction the grains tarnish coppery red and in a third direction they become dull lead gray. Granular aggregates which have been exposed for some time look like a mixture of three minerals and the nondescript appearance is heightened by the quartz filled cracks, minute chalcopyrite grains and scattered pyrite and molybdenite. The streak is dull lead gray and only assumes a barely perceptible reddish gray tinge with long rubbing. The mineral scratches calcite but with difficulty and its hardness is thus about 3.3 to 3.5. PYROGNOSTICS, ETC. Benjaminite is soluble in hot concentrated nitric or hydrochloric acid and the solution gives the usual qualitative reactions for silver, copper, bismuth, and lead. Alone on charcoal it yields sulphurous fumes but is not reduced. With potassium iodide-sulphur mixture the usual conspicuous bismuth coating is obtained. In the closed tube it gives only a ring of sulphur and in the open tube only sulphur dioxide without the formation of any sublimate. MICROSCOPIC PROPERTIES. In polished sections under the metallographic microscope the ben- jaminite is medium gray, the color being about that of the average tetrahedrite. Examined with polarizing reflecting apparatus the mineral is found to be uniformly and very decidedly anisotropic but it exhibits no color pleochroism. When the surface is treated with the standard microchemical reagents hydrochloric acid, ferric chloride, mercuric chloride, and potassium hydroxide give negative results. With reagent nitric acid the surface effervesces and blackens and the fumes tarnish brown. These properties, according to Davy and Farnham’s scheme, would identify the mineral as aikinite, thus seemingly substantiating the qualitative identification. ANALYSES AND COMPOSITION. The specimens were at first labeled aikinite and the mineral not only gives the qualitative reactions of aikinite but greatly resembles the aikinite from Beresov, Siberia in the Museum collections. The analysis was at first undertaken as of aikinite from a new locality and was temporarily discontinued owing to the inhomogeneous 6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 appearance of the material. A specimen was then polished and examined carefully by modern metallographic methods and, avoiding molybdenite and the scattered large grains of pyrite, was found to be homogeneous except for the small percentage of chalcopyrite. Four analyses were made in all on separate specimens, each of which was carefully selected and studied metallographically. In analysis 1 the presence of silver was not suspected and it was weighed with the copper. In analysis 2, made a year later, a large error was made by inadvertently filtering off a large part of the lead and weighing it in the form of sulphate, with the quartz. The value for lead in this analysis was adopted arbitrarily from the mean relation of lead to bismuth in the other three and the insoluble matter and sulphur were corrected in accordance. The results are given here because the determinations of copper, silver, and bismuth are of value. The analyses were made at intervals over three years and with variously modified procedures. Each analyzed sample was a thin slice which had been polished and examined metallographically and selected free from pyrite and with a minimum of molybdenite. These were crushed and screened to pass 100-mesh screens, the dust removed, and the quartz floated out by a gravity separation with methylene iodide. The quartz present in exceedingly thin veinlets yielded mixed grains so that the samples could not be entirely freed from quartz. The small chalcopyrite grains associated with the quartz could not be avoided although in one case they were largely removed magnetically. The results of the analyses are stated in detail, sepa- rately, below. Analysis 1 of benjaminite. : es Deduc- Recalcu- Constituent. Original. tions.

Analysis 3 is the most dependable analysis of the four since the material was not only well selected but the method most suited for the several separations had been determined by the previous work. The powder used for analysis was, moreover, treated to a magnetic separation whereby a large part and possibly all of the chalcopyrite was removed. Although the iron found is considered below to be present as admixed chalcopyrite which is deducted, it is possible that the amount found in this analysis is essential to the benjaminite occurring as an isomorphous replacement of the lead. This would not affect the formula below derived but would rather tend to support it by bringing the analytical results into closer agreement with the calculated percentages. The analysis is as follows: Analysis 3 of benjaminite. : ons Deduc- Recalcu- Constituent. | Original. iawns: Net. lnted: | @ iar zien es cael eee Fd 8. 86 SHSGr Ce See ee Se ie eS INES teen ental PN ZO) oes Se reer 21. 70 | 25. 25 (Cop peheteae eae asec eeaae | 6. 65 ~ 65 6. 00 | 6. 98 SUA) a ae Se | QE SM wee ate eee 2. 78 | 3. 23 pronase 27525 20 oi Aue pera Wa dee PAD 8 | . 58 HOSs eee tes |e eran a Bismuth Amn s E Rae ei EN | AN Aliya lee oe am mm 41. 45 | 48. 24 Molybdenum-_------- wen aes | 1. 30 1S 0 Se ets ee ee ee Sul humsees eee ee | 15. 53 1. 53 14. 00 16. 30 Motels. 2/2 pe eet tete ete 98. 85 12. 92 85. 93 | 100. 00 45554—25—Proc.N.M.vol.65——44 8 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 65 The deductions amount to quartz 8.86 per cent, molybdenite 2.17 per cent and chalcopyrite 1.91 per cent.
