conspicuous on the elytra. Head transverse, convex, broadly, feebly arcuato- 

 truncate at base but not impressed ; temporal angles broadly rounded to the 

 eyes, which are large and very prominent; i^unctures fine and feeble, sparse; 

 antennjc about as long as the head and prothorax, slender, the club 

 moderately thick. Prothorax small, scarcely three-fourths as wide as the head, 

 not (juite as long as wide, narrowly rounded at the sides anteriorly, thence 

 parallel and distinctly siniiate to the basal margin, which is distinct and as 

 wide as the disk; collar short, parallel, moderate in width; disk convex, 

 strongl}' and denseh' i)unctate, the punctures polygonally crowded. Elytra 

 two-thirds longer than wide, fully two and one-half times as wide as the pro- 

 thorax, parallel and feebly arcuate at the sides, the apex broadly and semi- 

 circularly rounded ; humeri rather broadly exposed and rounded to the pro- 

 thorax ; post-scutellar impression broad and feeble, the omoplates almost obso- 

 lete; punctures coarse, de^p and sparse. Abdomen minutely and somewhat 

 sparsely punctate, polished, clothed Avith rather long and coarse pubescence. 

 Legs rather short and stout. Length 2.25-2.5 mm., width 0.8-0.9 mm. 



Texas (Austin). 



The description is drawn from the female, but the niale scarcely 

 differs in general form, except that the elytra are less dilated 

 behind. 



The male has the anterior and intermediate trochanters acutely 

 angulate and prominent posteriorly, but scarcely spinose, the 

 corresponding tibiae unmodified, the fifth ventral short, scarcely 

 visibl}' longer than the fourth, broadly rounded or subtruncate, 

 with a finely beaded edge at apex but unmodified on the disk, 

 the genital segment subcorneous, flat, smooth, transversely and 

 "widely truncate at apex, the edge provided with a few widely 

 spaced short stiff" setai, the copulatory sheath moderate in length, 

 flat, straight in profile, the sides subparallel or just visibly con- 

 vergent and straight from the base nearh' to the apex, where it 

 is abruptly narrowed and produced in a slender acute point ; on 

 the upper surface it is obtusely and strongl}' carinate along the 

 median line, the carina continuing along the narrowed apical 

 spicule to the extreme apex; the efferent duct is shorter than the 

 upper and penetrative organ, and both together project from a 

 short basal sheath in the nature of a second genital or psuedo- 

 segment. Four specimens,

Rather narrow, convex, shining, the pronotum and abdomen 

 dull, pale rufo-testaceous, the antennal club and elytral suture 

 blackish ; pubescence pale, short and moderately dense, coarse,
