EEVISION OF LISTROCHELUS — SAYLOR 107 



ment convex, impunctate in basal half and coarsely punctate in apical 

 half, with a distinct though very blunt transverse carina at the center. 

 Inner front claw always with a distinct tooth at center, all others 

 (rarely the inner claws of both kind and middle tarsi have faint traces 

 of a larger tooth) serrate apparently along a single margin, and without 

 larger intercalated teeth. 



Female. — Antennal club equal to fmiicle. Punctation of head much 

 coarser and denser than m the male. Pygidium flattened, with sparse, 

 fine punctures and very short, suberect hair, the punctures in the 

 apical poUshed half of the disk very sparse; basal discal area pruinose 

 or subpruinose. Abdomen polished, evenly convex, \vdth sparse and 

 fine setigerous punctures; sixth segment and apical half of the preced- 

 ing stemite more coarsely punctate than the remaining segments. 

 All claws with a strong median tooth, surface basad of the tooth ser- 

 rate (hind claws in one female worn and the larger teeth barely visi- 

 ble). Otherwise as in male. 



Length. — 11-14 mm. Width. — 5.5-6.8 nun. 



Types. — From Brownsville, Tex., Jmie 5, 1932 [Savior], deposited in 

 the United States National Museum (No. 53770). 



Paratypes: Males, 13; females, 4. Texas: Esperanza Ranch, 

 Brownsville, July (Schwarz) [U.S.N.M.j; Del Rio, July 23, 955 feet 

 (Wickham) [U.S.N.M.J; Sabinal, June 8 (Pratt) [U.S.N.M.]; Browns- 

 ville, July (Linsley) [Saylor and Snow Museum]; Sanderson, July 

 1937 (Al Meade) [Saylor]; Stillwater, July 4, light trap [Reinhard],' 

 San Juan, May 10 (Stugard) [Sanderson]; Uvalde, June 15 and May 

 (Linsley) [Saylor]. 



Remarks. — Externally probably closest superficially to L. cushmani, 

 but quite different in the male genital and claw characters. The male 

 genitalia of the present species are not closely similar in form to any 

 others in the genus.

Male. — Robust-oval to elongate-oval, testaceous to rufotestaceous, 

 thorax and head rufous, strongly shining; elytra subpruinose to shining. 

 Head with front coarsely, moderately densely, variolately punctate^ 

 apparently glabrous; vertex with transverse carina strongly elevated, 

 surface behind this impunctate; clypeus punctured as front but a little 

 less densely so and usually with small impunctate area at center of 

 disk, apex sub truncate, angles greatly rounded, giving the clypeus 

 almost a semicircular appearance, apex moderatelj'' refiexed; clypeal 

 suture strongly biarcuate. Antenna 10-segmented, rufotestaceous, 

 club testaceous, one-fifth to one-fourth longer than funicle to almost 

 one-third longer, segments 6 and 7 of funicle transverse and prolonged
