REVISION OF LISTROCHELUS SAYLOR 95 



shorter than fifth, slightly subrugosely, sparsely punctate, with mod- 

 erately long erect hairs. All claws moderately coarsely serrate along 

 a single margin, \^dthout intercalated larger teeth on front tarsi; first 

 segment of hind tarsi slightly shorter than second. 



Female. — Antennal club shorter than funicle. Clypeus with small 

 impunctate area at center base (usually). Pygidium convex, mod- 

 erately densely and not coarsely punctate, with short suberect hair, 

 punctures sparser in apical third, basal half of disk subopaque, re- 

 mainder polished. Abdomen convex, highly polished, segments 2-4 

 inclusive sHghtly, transversely gibbose. All tarsal claws serrate along 

 a single margin, with a fine triangular tooth at the middle (hind claws 

 worn in the single female at hand and appear to lack the central tooth, 

 although Bates in liis original description of the species says all claws 

 have the central tooth). Otherwise as in the male. 



Length. — 11.5-13.5 mm. (to 17 mm. in var. major of Bates). 

 Width. — 5.5-6.5 mm. 



Type. — In the British Museum (Natural History). 



Type locality. — "Villa Lerdo in Durango, also Tapachula in Chiapas, 

 Mexico." 



Specimens examined. — Males, 16; females, 17. Texas: Presidio, 

 August [Saylor], June 28 [Reinhard], and July 18 [Saylor]. Mexico: 

 Torreon, Chiapas, June 17 (Al Meade) [Saylor]; Coahuila [Robinson]; 

 San Antonio, Durango, 5,000 feet, June 10, 1937 (Meade) [Saylor]. 

 Villa Juarez, 300 feet, May 20, 1937 [Saylor]; J. Manuel, El Salto, 

 Durango, June 5, 1937 [Saylor]. 



Remarks. — Specimens from Texas and Mexico were compared with 

 the types in the British Museum and found to agree well. Rare in 

 the United States and not heretofore recorded from this country, but 

 may be quicldy placed by the male genitaha, which in form have no 

 close relatives in oiu- fauna, and by the strongly convex thorax of the 

 female.

Male. — Oblong-ovate, rufotestaceous to somewhat piceotestaceous 

 at times, elytra usually slightly to completely pruinose, otherwise 

 shining above, pUose. Head with front very coarsely, densely, and 

 rugosely punctured, frequently with a suggestion of a longitudinal 

 carina, with sparse, short, erect hair; vertex with strong transverse 

 carina, area posterior to carina impunctate; clypeus densely strongly 

 punctured but usually not so densely so as front; apex clypeus very
