REVISION OF LISTROCHELUS — SAYLOR 89 



pruinose or highly poHshed; sixth shorter than fifth, sHghtly trans- 

 versely flattened, finely densely punctate, with moderately long hairs. 

 All tarsal claws finely pectinate along a double margin, the outer front 

 claw only with a large subapical triangular tooth; the hind claws often 

 pectinate-serrate rather than entirely pectinate (especially the inner 

 and shorter row of pectinations). First segment of hind tarsi subequal 

 to or slightly shorter than the second. 



Female. — Antennal club subequal to funicle. Pygidium slightly 

 convex and highly pruinose in basal half, strongly flattened and 

 polished apically; disk with moderately fine and somewhat dense 

 setigerous punctures, the hairs erect and short; apical half of disk 

 usually less densely punctate and with a slight to moderate median 

 longitudinal impression. Hind inner claw without a larger tooth, all 

 other claws with a strong, triangular, intercalated tooth slightly be- 

 yond the middle, the surface from large tooth to base serrate to sub- 

 pectinate, along a double margin. Otherwise as in the male. 



Length. — 15-18.5 mm. Width. — 7.5-8.5 mm. 



Type. — Male in United States National Museum; female in the 

 Dike collection. 



Type locality. — "Skidmore, Texas." 



Material examined. — Males, 9; females, 4. Texas: Corpus Christi, 

 Oakville in April, Pleasanton in February, Bexar County and Stephen- 

 villo on April 5. 



Remarks.- — Close to L. mucorea and allies but quite distinct, at 

 least in the male sex. I have been unable to find characters either 

 genitalic or otherwise that will hold in a series in separating the fe- 

 males but am confident that females of both species are present in the 

 material at hand. Varies somewhat in the density of the elytral 

 pruinosity, especially in the females.

Mai<?.— Elongate-oval, rufocastaneous to piceocastaneous, sides of 

 thorax and larger part of elytra usually pruinose, elytra with sparse 

 minute hair, otherwise glabrous. Head and clypeus densely and 

 coarsely punctate, transverse occipital ridge strong and entire; apex 

 clypeus sharply reflexed, thickened, subtruncate, angles rounded. 

 Antenna 10-segmented, segment 3 longer than 2, 4 and 5 subequal 

 and each shorter than 3, 6 and 7 transverse; club one-fifth (or less) 

 longer than funicle. Thorax densely, moderately coarsely pimctate, 

 with a smooth median longitudinal stripe; lateral margins finely to 

 coarsely crenulate and ciliate; basal m^arginal line entire and ciliate; 

 hind angles obtuse but obvious, front angles obtusely rounded.
