VIII, KOREA VASCO M. TANNER Professor of Zoology and Entomology Brigham Young University The ten species discussed in this report were all collected in the proximity of Seoul, Korea. The writer is pleased to thank Capt. Ted Tibbitts of the U.S. 5th Epidemialogical Field Unit for these speci- mens. Captain Tibbetts, a former student of this institution, has sent many valuable reptile specimens to us. While he was stationed in Florida, he sent us many rare species for the museum collection. He is a good preparator, which makes the material doubly valuable. The Korean peninsula, with a surface area of about 85,246 square miles, extends from Manchuria, 43° 2' N. latitude, southward to 38° 12' N. latitude. The Eastern most point, near the mouth of the Yalu River, is Maando, 124° 11' East longitude. The land boundary is formed in large part by the Yalu and Tumen rivers; which separate Korea from South Manchuria and Eastern Siberia. The Russo-Korean frontier, only 20 miles long, is about 80 miles from Vladivostok. Korea is divided into fourteen provinces, each of which is subdivided into counties and districts. Following Warld War II, the peninsula was divided into North and South Korea. In September, 1947, South Korea (the American Zone south of latitude 38° N.) had a population of between 20 and 21 million people, and North Korea (the Soviet Zone, north of 38° N. latitude) had 8 million making a total for the country as a whole of betw^een 28 and 29 million inhabitants. Seoul, the cultural center of Korea, and since 1392 the Capital, is located midway between the north and south extremities and not (1) Contribution No. 138 from the Department of Zoology and Entomology. 67 mi.

It is the largest city with a population of about 1400,000 people. The country is very mountainous. The climate is similar to that of New England and Central East Atlantic States. The national economy is largely based upon agriculture. Mining, and related in- dustries are concentrated in the northern zone. Rice, the staple food crop, is grown in small plots of a few acres in the southern zone. The forests have been badly depleted in the past. A program to restore them, which was initiated by the Japanese, is still being carried for- ward. The reptile fauna of Korea is closely related to that of the sur- rounding regions. Slevin (1925) reported twenty-four species from this country. In this list there are two species recorded, which are not found in the Slevin list.

It will be noted that the specimen described above does not agree in all details with the descriptions of amurensis. It has four inguinal pores on each side while amurensis is described as having three on each side; wolteri, which is found in Korea, has only one inguinal pore on each side. This specimen does not have a white streak from the eye to the collar. Mr Slevin reports this species from many localities in Korea. EREMIAS ARGUS PETERS Peters, 1869, Mon. Ber.

The Great Basin Naturalist 74 Vol. XIII, Nos. 3-4 A NOTE ON THE COMMON LOON IN SOUTHERN COLORADO The status of the Common Loon (Gaxna iinrner hnmer I as a winter resident in the San Luis Valley (an intermontane basin) of southern Colorado has apparently been a point of question for many years. Bergtold (A Guide to Colorado Birds, 1928) maintains that it o.nly oc- curs as a rare migrant. Booth (Birds of the West, 1948) describes it as wintering mainly on the west coast, while Bailey (Handbook of Birds of the Western United States (revised ed.), Houghton Mifflin Co., Boston, 1935) has it wintering over all of the United States. An un- published checklist by Donald A. Ryder in 1950 lists it as questionable, with the only record being from the Sangre De Cristo Range of moun- tains that lie east of the valley. Another unpublished list by Dr. Paul Cecil Bibbee for the summer of 1950 does not even include the Com- mon Loon. In the interest of clarifying this situation, I would like to report that a specimen was taken on February 24, 1953 at the state fish hatch- ery near La Jara. Colorado, which is in the southern part of the San Luis Valley. The bird was shot while disturbing the trout and then kept frozen for several days, after which, I acquired it and had it mounted for our museum here at Adam's State College. It is in full winter plumage. Joseph C. Daniel, Jr. Biology Dept. Adam's State College Alamosa, Colorado GEOPHILOID CIIILOPODS OF THE HAWAIIAN AND OTHER OCEANIC ISLANDS OF THE PACIFIC RALPH V. CHAMBERLIN University of Utah Through the courtesy of N. L. H. Krauss, several small collec- tions of chilopods and millipeds from the Pacific islands have come into the author's hands. These collections have added considerably to the known myriopod fauna of these islands. Thus the present pa- per contains descriptions of five new species in the Geophilida, three of which represent new genera, these bringing the total number of members of this order now known from these oceanic islands to seventeen. In addition to these new forms, occasion is taken to in- clude descriptions of a new Mecistocephalus from Malaya and of a new Ballophilus from Hong Kong, the types of which were also col- lected by Mr. Krauss. The types of the new species are all retained in the author's collection. SCHENDYLIDAE Genus NYCTUNGUIS Chamberlin Nyctunguis Chamberlin, 1914, Bull. Mus. Comp. Harvard, vol. 58, p. 201.

GENUS LANONYX, new Like Mexiconyx of Mexico and Plesioschendyla of New Cale- donia, in which the coxal pore is similarly single and homogeneous, in lacking ventral pores on the sternites. While agreeing with Mexiconyx in possession of a claw on the anal legs, aside from lack- ing ventral pores, it differs superficially from that genius in the much shorter prehensors.

Head short, with antennae relatively long, filiform; head fully covering the prehensors in dorsal view. Prehensors when closed not attaining front margin of head; claws slender; all joints unarmed. Anterior margin of prosternum without teeth but with two low^ tubercular eminences adjacent to median excision suggesting teeth; chitinous lines faint. Ventral pores absent. Last ventral plate very wide. A single large coxal pore on each side, the gland especially large, homogeneous. Anal leg in the male notably crassate; ending in a well devel- oped claw.

BALLOPHILUS ROUXI Silvestri This species is like B. alluadi Ribaut in lacking pores on the last four sternites. It differs from the former species in lacking all in- ternal pigment and from both in the more strongly clavate antennae, in having the head wider than long as well as in not having the ster- nal poriferous areas elevated. The number of pairs of legs is the highest recorded for any species. Oryidae Genus ORPHNAEUS Meinert ORPHNAEUS BREVILABIATUS (Newport) Geophilus hrevilabiatus Newport, 1845, Trans. Linn. See.

Dec. 30, 1953 geophiloid chilopods of the pacific 81 MECISTOCEPHALUS VVAIKANEUS Chamberlin, new species Reddish yellow, the head and prehensors chestnut. Cephalic plate nearly twice as long as wide; slightly narrowing caudad from the frontal region over about two-thirds of the length, and then more abruptly to caudal end; caudal margin straight, the anterior obtusely subangular. The pleural tooth short and conical, directed straight forward. Anterior clypeal area much exceeding the posterior, its median length being about four times as long as that of the latter. Median piece of labrum comparatively large, narrowly shield shaped, its acute, subdentiform caudal apex projecting freely beyond margin of lateral pieces. Lateral pieces with caudal margin oblique and nearly straight, the mesal corners not produced. Palpi of second maxillae of normal sternal impression weak, not furcate anteriorly. Last ventral plate longer than wide, narrow, trapeziform, Coxal pores small, typically seven on each side. Pairs of legs, 49. Length, 20 mm. Locality: Hawaiian Is.: Waikane Id. Two specimens taken in rotten log on Dec. 28. 1928. GENUS FUSICHILA, new Differing from all other genera of the Mecistocephalidae in having the labrum composed of a single piece, this probably formed by the fusion of the lateral pieces and the suppression of the median piece. Coxal pores very few in number, the type showing only two on one side, four on the other. Generotype: FUSICHILA WAIPAHEENAS sp. n. FUSICHILA WAIPAHEENAS Chamberlin. new species Body in general yellow, the head and prehensors dusky chestnut. The head nearly twice as long as broad; conspicuously nar- rowed over posterior half; anterior margin slightly convexly angular between the rounded corners. Pleural tooth conical, straight. Anterior area of clypeus larger than the posterior, dividing the latter with a narrow extension down the middle line. Labrum broad anterocaudally at middle, narrowing laterad on each side, with the caudal margin straight and wholly smooth and the anterior margin convex. Palpi of second maxillae relatively short, though longer than The Great Basin Naturalist 82 RALPH V. ciiAiMBEnLiN Vol. XIII, Nos. 3-4 in M. tahitiensis; last joint bluntly rounded at end, bearing a well developed claw and about seven stout setae. Sternal impression deep posteriorly, not furcate anteriorly. Last sternite broad anteriorly, strongly narrowed caudad, the caudal margin convexly rounded.

Generotype: ZELANION DUX Chamberlin This is a genus heretofore known only from New Zealand where it is represented by some ten species. Attems (op. cit.) merges this genus with his Sepedonophilus; but it seems adequately distinct in lacking lappets on the syncoxite of the first maxillae and in lacking the conspicuous process of the mesodistal angle of the coxa of the second maxillae. ZELANION HAWAIIENSIS Chamberlin, new species Dorsum of type as preserved a somewhat dusky brown, with head and prehensors chestnut and legs yellow. Frontal suture not evident. The single clypeal area on anterior border, large, white in color; bearing no setae, but a single seta at caudolateral edge on each side, with no other setae adjacent to this area. Lateral pieces of labrum nearly meeting in front of the median piece, pectinate throughout length; median piece bearing four dark, stout teeth. First maxillae with syncoxite bearing no lappets; first joint of palpus with a short lappet. Claw of second maxillae long and nearly straight, the articles setose on mesal side. Prehensors surpassing the head anteriorly; claw armed at base with an acute tooth; prefemur with a nodular tooth at distal end and showing a low, very obtuse prominence at middle; presternum with sclerotic lines not evident, bearing two teeth anteriorly. Dec. 30, 1953 geophiloid chilopods of the pacific 83 Dorsal plates deeply bisulcate. Last ventral plate narrow, trapeziform. Each coxa bearing ventrally about twelve simple, well separated, pores of nearly uni- form size. Anal legs of male crassate, but last three joints thinner, the second tarsal slender and bearing a claw. Pairs of legs, 39. Length, 28 mm. Locality: Hawaii. One male. Differing from the New Zealand Z. sitocala (Attems), which in general it resembles, in lacking setae on the clypeal area proper and setae adjacent thereto excepting the two above mentioned, in having four instead of five teeth on the median piece of labrum, and in the fewer, more uniform coxal pores, etc. Genus PACHYMERIUM C.

A widespread palearctic species, common in Europe and North America. It has been found on Hawaii where undoubtedly intro- duced. Genus NESOMERIUM, new A single, finely areolate clypeal area. Labrum well developed, tripartite; the lateral pieces overlap- ping the median in front, strongly pectinate throughout; median piece bearing long pectiniform teeth, typically not more strongly sclerotized than those of the lateral pieces. Mandible with three or four pecrinate lamellae. First maxillae apparently lacking palpi; the median processes bearing papillae on mesal surface, without setae. Claw of palpus of second maxillae not pectinate; distal and second joint strongly setose; coxae completely fused. Ventral pores present in front of caudal margin of sternites. Last ventral plate very wide. Coxal pores one on each side, this large and simple. The Great Basin Naturalist 84 RALPH V. CHAMBERLIN Vol. XIII, NoS. 3-4 Tarsi of anal legs biarticulate, not bearing a claw. Generotype: NESOMERIUM HAWAIIENSE, new species Differing from Pachymerium in the characters of labruni and first maxillae and in having but a single large coxal pore on each side instead of numerous small ones. NESOMERIUM HAWAIIENSE Chamberlin, new species Head longer than wide in about ratio 3.8:3; corners rounded; the width nearly uniform or slightly wider behind than in front; sides weakly convex; anterior margin straight; no frontal suture. Lateral pieces of labrum nearly meeting at middle in front of middle piece; closely fringed with basally stout, distally fine, teeth; piece bearing 10-12 long, distally fine teeth resembling those of the lateral pieces. A single median clypeal area, this, in the type, white in color the area small and bearing on middle two erect setae. Coxae of second maxillae completely fused; end of palpus bearing about fif- teen rather long, stout setae and a large, simple claw; the adjacent joint with about six syncoxite of the first maxillae in the form of a narrow band lying beneath the anterior border of the syncoxite of the second maxillae; median processes subconical, convex on the outer side, flattened on the inner, this mesal surface bearing numer- ous papillose processes some of which are rounded or tubercle-like; the first maxillae apparently lacking developed palpi. Prehensors surpassing the head in front; claw armed at base as is also each of the preceding three joints. Ventral pores in a transverse area in front of caudal margin of sternites, the area widest at middle and narrowing acutely on each side. Last ventral plate very wide, subtrapeziform, but its sides strongly convex; the caudal margin straight or slightly concave. One large coxal pore on each side, this wholly covered by the stern- ite. In the male the third, fourth, and fifth joints of the anal legs inflated, the two tarsal joints slender. Pairs of legs, 69. Length, about 45 mm.

Previously reported by the author from Ocean Id., Laysan Id., Johnson Id., and Pearl and Hermes reef, the present collection con- tains a specimen from Canton Id. in the Phoenix group collected by Mr. Krauss in Oct., 1950. This species appears to be a beach-dwelling species, and a rather wide distribution on the Pacific islands would not be sur- prising. Genus MARSUKOMERUS Attems Marsukomerns Attems, 1938, Proc. Zool. Soc. London, ser. B, vol. 108, pt. 2, p. 372. A genus resembling Honuaphilus in having a single large coxal pit on each side, but the gland is represented as strictly simple whereas that of Honuaphilus is conspicuously composite, numerous independent simple glands opening into the common large tube or cavity, the single labral piece of Marsukomerus also is distinctive. MARSUKOMERUS PACIFICUS Attems Marsukomerus pacificus Attems, 1938, Proc. Zool. Soc. London, ser. B, vol. 108, pt. 2, p. 373. The type specimen was taken on Hawaii and provides the only record so far. A NEW SPECIES OF ACOMATACARUS (ACARINA, TROMBICULIDAE) FROM UTAH DORALD M. ALLRED University of Utah D ELDEN BECK Brigham Young University During the course of some sylvatic plague surveys, animals and nests of Neotoma lepida lepida Thomas were collected. Upon exami- nation, Chiggers found on one adult male woodrat proved to be suf- ficiently different that they are herein being described as a new species. ACOMATACARUS SEXACIS Allred and Beck. n. sp. Body: Engorged specimens of this species are relatively large, measuring up to 940 by 661 microns. Gnathosoma (Fig. 2) : All the palpal setae are branched. The palpal tibia has a bifurcate claw, the large axial prong being internal to the smaller accessory prong. The palpal tarsus has seven branched setae and one spur. The galeal seta has five branches on the outer edge. Each cheliceral blade has one large subapical laterodorsal tooth and apparently six subequal ventral teeth. Scutum (Fig. 1): The shape is roughly rectangular, with a moderately convex posterior border. There are no punctae. Ihe sensillary bases are well separated and are on a level with the pos- terolateral setae. The sensillae are moderately long and without branches or barbs. Standard measurements of the scutum of the holotype (first series) and five of the paratypes are as follows: AW PW SB ASB PSB AP AM AL PL S 67 85 30 28 44 39 54 67 87 31 28 26 28 41 38 51 69 68 92 30 28 24 30 48 43 60 82 68 85 30 30 22 24 44 40 54 75 68 85 30 21 25 44 41 54 72 68 85 30 19 25 41 38 48 75 68 86 30 29 22 27 44 40 54 74 Ave. Legs: The approximate lengths of the legs and the setal arrange- ments are as follows: Leg L322 microns; coxa, 2 plumose; trochanter, 1 plumose; femur, 6 plumose; genu (Fig. 3), 5 plumose, 1 genuala, 87 88 ALLRED AND BECK The Great Basin Naturalist Vol. XIII, Nos. 3-4 1 microgenuala; tibia, 9 plumose, 2 tibialae, 1 microtibiala; tarsus, 25 plumose, 1 spur, 1 microspur, 1 subterminala, 1 two-branched parasubterminala.

Body Setae: The dorsal setae vary in number from 52 to 56 in six specimens examined. The anterior and posterior rows are obscure, but the approximate ratio of the holotype is 8:9:2:6:10:8:6:2:2. The humeral and lateral setae of the dorsum are longer than the middle and posterior setae. The majority of the anterior and posterior setae are equal in length, except for a few anterior setae which are slightly shorter. The lengths of the posterior dorsal setae vary from 41 to 44 microns. The ventral setae vary from 52 to 54 in number, and are longer posteriorly. ACOMATACARUS SEXACIS, new species Fig. 1. Scutal Plate Fig. 2. Left Half of Gnathosoma (Doi'sal View) Fig. 3. Right Genu I (Dorsal View) Type Data: The holotype and 8 para types were taken from an juhilt male Neotoma I. lepida 10 miles south of Antimony, Garfield County, Utah by M. Killpack and M.

Discussion: In Greenberg's key (1950) to the species of Acorna- tacarus of the New World, this species runs to A. micheneri. It dif- fers from micheneri, however, in several aspects (lable I). Although Greenberg designates A. micheneri as lacking in a microgenuala I, Brennan (correspondence) signifies that this species is extreinely variable and does possess it.

DRAKE Iowa State College, Ames, Iowa The present paper is based upon specimens of Tingidae kindly loaned me by Dr. W. E. China, British Museum of Natural History, London, and Dr. R. E. Sailer, U. S. National Museum, Washington, D. C. Some records are also from my private collection. I also de- sire to express my sincere appreciation to Dr. 11. Schouteden, Konin- kijk Museum van Belgisch Congo, Tervuren, Belgium, for the privi- lege of examining the many types and specimens of tingids from Belgium Congo and other regions of Africa. The types of the new species described herein are deposited as stated beneath each descrip- tion. In the comparative measurements. 80 units equal one milli- meter. CROMERUS EXCELANS Drake, new species Long, moderately stout, densely clothed with very fine, short, golden pubescence. Head black-furrugineous, with short brownish spines, the median sometimes absent. Rostrum dark brown, reaching to base of mesosternum. Bucculae closed in front. Orifice distinct. Legs rather short, dark ferrugineous. Antennae dark brown to dark ferrugineous, very shortly pilose, measurements — I, 12; II, 25; III, 140;IV, 85. Pronotum moderately convex, dark ferrugineous, with median carina sharply elevated; lateral carinae absent or at time fairly distinct on posterior triangular process; calli impressed, black; collar mostly biseriate, truncate in front; paranota represented by low narrow cariniform ridge which is wider and thicker opposite calli. Elytra long, with the short golden pubescence almost as dense as on pronotum; costal area narrow, uniseriate. the areolae small, a little larger opposite apex of discoidal; subcostal area biseriate, the cells small; discoidal area narrowed at both ends, widest a little beyond middle, there six cells deep; sutural area with small cells behind discoidal, then larger cells apically.

C. invarius (Walker) has different antennal measurements (I, 28; II, 14; III, 128; IV, 104) and more convex and coarsely punc- tate pronotum. CROMERUS BIMACULATUS (Distant) Teleonemia bhnaculata Distant, Rec. Ind. Mus., 3(2):166, 2 figs., 1909. A study of the type (male) of Teleonemia bimaculata Distant in the British Museum shows that it is a typical member of the genus Crornerus Distant, and it is here so transferred (New Combination). The original description is accompanied by fine illustrations of the type. The antennal measurements are — I, 22; II, 10; III, 100 and IV, 85. The median carina is composed of one row of small areolae; known only from the type, taken in Borneo. Genus LASIACANTHA Stal. Lasiacantha Stal, Enum. Hemip., 3:130., 1873. Jannaeus Distant, Ann. See. Ent. Belg., 53:118. 1909. As the type species of the genus Jannaeus Distant (J. cunneatw; Distant) is a typical member of the genus Lasicantha Stal (TyP^^ odontostoma Stal), the former is relegated here to synonymy; Jan- naeus cuneautus Distant now becomes a valid species of Lasiacantha (New synonymy and new combination). In addition Jannaeus al- timitratus Takeya is also transferred to Lasiacantha (New combi- nation). The other two species described as Jannaeus are being transferred to a new genus erected below. HURDCHILA Drake, n. gen. Head short, with short spines, partly concealed by the hood. Orifice with a long, prominent, tube-like canal with inferior surface removed. Rostum long; laminae foliaceous, areolate, subparallel, open behind. Bucculae areolate, contiguous in front. Ilypocostal laminae areolate. Antenniferous tubercles short; antennae mode- rately long, slender, shortly pubescent; segments I and II short, stout; III long, very slender; IV short, swollen. Pronotum extremely long, moderately convex, with three long, strongly elevated carinae; hind triangular part extremely long, areolate, not quite attaining apex of discoidal area; paranota large, long, strongly reflexed, resting partly on surface of pronotum; hood moderately large, more or less Dec. 30, 1953 new genera and species of tingidae 93 inflated, produced in front of collar, sometimes beyond apex or head. Elytra longer than abdomen, not abruptly widened near base; divided into the usual areas; discoidal area reaching beyond middle of elytra. Type of genus, Jannaeus torgularis Drake and Poor. In addition /. mirus Drake and Poor is also transferred to this new genus (New combination). Erected in honor of Marguerite Poor Hurd who has written many papers on Tingidae as well as drawn many fine illus- trations of lacebugs. The slender pubescent antennae without long bristly and modi- fied hairs and unarmed outer pronotal and elytral carinae, boundary veins of elytral areas, extremely longly produced hind process of pronotum separate Hurdchila from Lasiacantha. Genus KAPIRIELLA Schouteden, 1919. Kapiriella Schouteden, Rev. Zool. Africa, Brussels, 6:138. 1919. Lembella Schouteden, Rev. Zool. Africa, Brussels, 6:139. 1919. (New Synonymy) A study of the generic types of the genera Kapiriella Schouteden (K. leplaei Schouteden) and (L. maynei Schouteden) show that the two species belong to the same genus and that it is now necessary to suppress the latter on the basis of page priority. The species are known only from the mainland of Africa. Lembella polita Drake (Proc. Biol. Soc. Wash., 61:150-151, 1948) is identical with K. leplaei Schouteden (loc. cit., p. 139) and thus placed in synonymy (New synonymy). The genus Kapiriella now comprises three valid species as follows: K. leplaei Schouteden, K. maculigera (Horvath), and K. maynei (Schouteden). It should also be noted that all three spe- cies exhibit considerable variation in the intensitv of the color pattern. Genus HAEDUS Distant, 1904 Haedus Distant, Trans. S. Afr. Phil. Soc, 14:432. 1904. Hormisdas Distant, Philip. Jour. Sci., 5(l):59-60. 1910 (New Synonymy). An examination of the generic types of the genera Haedus Distant (H. clypeatiis Distant) and Hormisdas Distant (H. pictus Distant) make it necessary to suppress the later as a synonym of Haedus. As Hormisdas pictus Distant, H. bellus Drake, H. diversit- atus Drake, H. elongatus Drake, H. lectus Drake, H. sideus Drake and Poor, H. vicarius Drake and H. villiers Drake are quite distinct and valid species, they are here transferred to the genus Haedus. In addition to the above and including the new species in press here and The Great Basin Naturalist 94 CARL J. DRAKE Vol. XIII, Nos. 3-4 elsewhere, the genus Haedus now contains 15 described species, and is represented in the faunas of Africa, Madagascar, East Indies and the Orient. The species are all small, slender, without distinct nie- tasternal orifice, and have long slender appendages. The antennal tubercles are long with blunt tips, about two-thirds as long as the first antennal segment. The outer margins of the paranota and elytra are serrate and also clothed (including entire dorsal surface) ^^^th short, pale, decumbent pubescence. The pronotum bears three long foliaceous carinae. HAEDUS JAV ANGUS Drake, new species Small, oblong, blackish fuscous with antennae, legs and all but apical part of costal area whitish testaceous. Head dark brown armed with five long testaceous spines (median and front pair with some brown), with tips curved downward. Antennae very long, slender, measurements — L 10; II, 8; III, 69; IV, 26. Antenniferous tubercles long, spiniform, brown. Bucculae brownish testaceous, contiguous in front. Legs long, slender, with tips of tarsi brownish. Pubescence sparse and pale. Hypocostal laminae uniseriate. Body beneath dark fuscous. Margins of paranota and elytra finely serrate. Pronotum tricarinate. each carina nearly equally elevated and composed of one row of small areolae, anterior part of median and lateral carinae pale testaceous, paranota slightly reflexed, biseriate, with areolae clear and moderately large, outer margin a little con- cave, front margin concave with the antero-outer apex terminating in a straight spine. Elytra considerably constricted bej'ond the mid- dle, widest near apex; costal area wide, biseriate, with large clear areolae; subcostal area mostly uniseriate, biseriate along raised boundary of discoidal; discoidal area elongate, about three-fifths as long as elytra, with apex and outer boundary beyond the middle elevated, with outer boundary vein deeply concave between eleva- tion and apex, three areolae deep in widest part; sutural area with veinlets and some of the cells fuscous. Length, 3.10 mm.; width, 1.11 mm. Type, Bandoeng, Preonger, Java. F. C. Drescher, British Mu- seum. Distinguished from H. licarius (Drake) by the larger size, long- er cephalic spines, darker color and more elevated apex and outer Dec. 30, 1953 new genera and species of tingidae 95 boundary (beyond middle) of discoidal area. The median carina is slightly more elevated than the lateral in vicarius. ABDASTARTUS LONGULUS, Drake, new species Head black, with four very long, slender, porrect, testaceous spines (median wanting). Antenniferous tubercles short, blunt, fuscous. Antennae very long, very slender, smooth, pale testaceous with basal segment partly embrowned, measurements — I, 18; II, 10; III, 88; IV, 34. Legs long, slender, smooth, pale testaceous. Hypocostal ridge narrow, uniseriate. Body long, slender, beneath blackish fuscous. Pronotum black, moderately convex, pitted, tricarinate, with very small areolae; median carina a little higher than lateral, pale in front; lateral carinae testaceous, slightly divergent anteriorly, the areolae tiny, barely visible; paranota very narrow, whitish, uni- seriate, the areolae very small. Elytra constricted beyond the middle, widest apically; costal area narrow, slightly wider apically, whitish testaceous, with cross-veinlets fuscous, the areolae narrow, some short, others long; subcostal area black-fuscous, biseriate; discodial area elongate, reaching to middle of elytra, black-fuscous, three areolae deep in widest part; sutural area with large cells, the veins and cells black-fuscous. Length, 3.00 mm.; width, 0.72 mm. Type (male), Dehra Dun, U. P., India, Sept. 2, 1951, R. N. Kuthari, Drake Collection. The very long antennae and legs and long slender body separate this insect from the two other members of the genus. Genus DULINIUS Distant Dulinins Distant, Ann. Soc. Ent. Belg., 47:48. 1903. Dulinius Distant, Fauna Brit. India, Rhynchota, 2:136. 1904. Sankisia Schoutenden, Rev. Zool. Africa, Brussels, 4(3): 293. 1906. As the type of the genera Dulinius Distant (D. conchatus Dist- ant) and Sankisia Schouteden (S. pulcra Schouteden) are congeneric, the latter is here placed in synonymy (New synonymy). Pulchra is a valid species, and it is here transferred to the genus Dulinius. In addition to conchatus Distant and pulchrus Schouteden, the genus Dulinius comprises bellus Drake, Kraussi Drake, nigrolineatus Dis- tant and the two new species described below. The type of the genus, The Great Basin Naturalist 96 CARL J. DRAKE Vol. XIII, NoS. 3-4 conchatus, was described from India, nigrolineatus from the Sey- ciielles and the rest from the mainland of Africa. DULINIUS CONGRUUS Drake, new species Broad, veinlets pale testaceous, areolae hyaline and without color markings. Antennae very long, densly clothed with fine, short, pale hairs, measurements — I, 20; II, 8; III, 110; IV, 50. Veinlets on sides of hood, convex surface of paranota and basal half of outer margins of elytra finely serrate. Orifice distinct, wdth testaceous rim. Bucculae open in front. Legs testaceous with tarsi brownish. Body beneath fuscous.

Elvtra verv wide, widest beyond middle, with outer margins diverg- ing posteriorly, with apices separated, with tumid elevation rather high and short, not attaining middle of elytra; costal area very wide, four areolae deep in widest part, a little turned up on expanded front margin; discoidal area wide, not attaining middle of elytra, sloping sharplv inward, composed of five cells, outer boundary vein highest a little before apex, there subangulate. Posterior surface of hood with several long pale hairs; veinlets of elytra with a few scattered, short, pale hairs. Type (female), Grahamstown, South Africa. October, 1952, Drake Collection. Allied to D. pulchrus (Schouteden), but readily separated from it bv the larger size, much wider costal area and shape of carinae. It ranks next to D. bellus Drake in size, but the latter is larger with much larger paranota, and the areolae are also distinctly larger. GENUS MECOPHARSA Drake, new genus Head short, with five spines. Rostrum moderately long; channel uninterrupted, open behind. Bucculae closed in front. Ostiolar canal Dec. 30, 1953 new genera and species of tingidae 97 distinct. Antennae slender, extremely long; segment I longer than head across eyes; 11 very short; III, long; IV extremely convex; punctate; tricarinate; hood rather small; paranota long, moderately wide, reflexed, areolate. Elytra broad, much longer and wider than abdomen, divided into the usual areas; discoidal area almost attain- ing middle of elytra. Reticulation distinctly lacy; pronotum pro- duced behind. Type of genus, Mecropharsa hackeri, n. sp. Allied to the genus Leptopharsa stal, but readily separated from it and other lacy genera of Tinginae by the very long slender an- tennae with the fourth segment unusually long and subequal to the third; the paranota are not enormously developed. MACROPHARSA HACKERI Drake, new species Moderately large, oblong, testaceous with head, disc of prono- tum and some veinlets in discal part of elytra embrowned. Eyes black. Body beneath brown. Head with five short testaceous spines, the anterior pair porrect and hind pair appressed. Rostrum brown- ish, reaching a little beyond mesosternum; laminae whitish, uniseri- ate, widely separated, open behind. Bucculae broad, areolate. Orifice with long prominently rimmed canal. Legs testaceous, very slender. Antennae testaceous with last segment mostly dark fuscous; segment I moderately swollen, four times as long as II; measurements — I, 36; II, 9; III, 90; IV, 90. Pronotum moderately convex, finely pitted, tricaiinate, each carina composed of one row of areolae; median carina a little higher than lateral, slightly arched on disc; lateral carinae feebly constric- ted behind disc, slightly concave within in front; hood small, sub- tectiform, feebly produced in front, paranota narrow, long, reflexed upright, with outer part curved in a little beyond the vertical line; hind triangular part areolate. Elytra rather broad, slowly widening posteriorly, overlapping a little but with the tips separated; costal area wide, triseriate in widest part, biseriate in front, the areolae large; subcostal area biseriate, with areolae small and rounded; dis- coidal area nearly reaching middle of elytra, narrowed at base and apex, widest at middle, there six areolae deep, the areolae rounded and slightly larger than in subcostal; sutural area large, with areolae larger in apical part, there as large as in costal area. Areolae hyaline. 'rtie Great Basin Naturalist 98 CARL J. DRAKE Vol. XIII, NoS. 3-4 I [ypocostal laminae uniseriate. Wings w hitish, longer than abdomen, much shorter than elytra. Length, 3.25 mm.; width, 1.25 mm. Type (female), Connondal, Queensland, Australia, H. H. Hack- ing, in Drake Collection. Separated at once from almost all other genera of lacy Tinginae by the form of the body, rather narrow paranota and extremely long fourth antennal segment, which is subequal in length to the third. Neocypselas Kirkaldy has the elytra abruptly widened near the base and enormously developed paranota. NESOCYPSELAS EVANSI Drake, new species Large, very broad, brownish with prominent dark fuscous mark- ings. Antennae slender, testaceous with apical third of terminal segment brownish, densely clothed with rather short, fine, pale hairs, measurements — I, 36; II, 12; III, 105; IV, 98. Head reddish fuscous, unarmed; eyes black. Rostrum reaching to base of mesos- ternum. Legs testaceous with last tarsal segment black. Orifice with a long channel. Bucculae not quite meeting in front. Hypocostal laminae very narrow, uniseriate. Body beneath dark reddish brown. Male parameres long, strongly curved. Pronotum moderately convex, very finely but not densely punc- tate, slightly shining, sparsely clothed with long fine hairs, tricari- nate; carinae pale testaceous, thinly foliaceous, without distinct up- right veinlets, the median carina disappearing behind disc; posterior process shortened, rounded behind, testaceous, areolate. Paranota extremely large, strongly reflexed, almost semiglobose, with outer margin high above disc and concave, longer than high, with almost every other transverse vein enlarged and infuscate, with veinlets (especially on lower half) finely serrate, the areolae largely em- browned with clear centres. Elytra very wide, abruptly widened near base with front margin there a little reflexed, with exterior margins finely closely serrate, with apices widely separated in re- sponse, with a wide band across basal part of costal area and another oblique subapical band (including areolae) dark fuscous; areolae l^etvs'een bands and in sutural area clear (transverse bands not fully formed in paratype) ; costal area very wide, six cells deep in basal three-fifths; subcostal area biseriate, with outer row of cells very small, the areolae clear; discoidal area elongate, not attaining middle Dec. 30. 1953 new genera and species of tingidae 99 of elytra, three cells deep in wddest part; veinlets with some fine short pale hairs which are more numerous on exterior margins. Length, 5.00 mm.; width, 3.00 mm. Type (male), Taveuni, Waiyero, Fiji Is., Feb. 2, 1924, Dr. H. S. Evans, British Museum. Paratype: 1 specimen, broken antennae, same data as type. NESOCYPSELAS EVANSI AEMULUS Drake, new subspecies Differs from typical form by the smaller size, biseriate discoidal area and narrower costal area (five cells deep in widest part). Last two segments of antennae wanting. Markings as in evansi. Length, 4.00 mm., width, 2.75 mm. Type (female), Bau, Fiji Is., Sept., 1922, H. W. Simmonds, British Museum. Paratype: 1 specimen (female), same locality and date as type. INDEX TO VOLUME XIIT The new genera and species described in this volume appear in black-face type in this index.
