apparently composed of evenly contiguous flat parallel scales ; intercoxal pro- 

 cess acutely triangular. Legs well developed, the femora all strongly clavate ; 

 tarsi slender, the basal joint of the posterior as long as the next two. 

 Length 1.65 mm. ; width 0.7 mm. 



Texas (Austin). 



A rather large and distinct species, which maybe distinguished 

 from any other of the present section by the small but pro- 

 nounced median tooth of the clypeus ; this tooth is not elongate, 

 however, as in the first section of the genus, but is equilateral 

 and triangular. It may be known from any of the larger species 

 of the first group of the genus by the strongly impressed prono- 

 tum. A single female specimen. 



64. C. calcaratum n. sp. — Stout and ventricose, polished and impunc- 

 tate, black throughout, the legs and antennae rufo-testaceous; pubescence 

 abundant, long, erect, rather coarse, pale and conspicuous on the elytra. Head 

 well developed, nearly as long as wide, circularly rounded behind, the eyes 

 rather small but convex and somewhat prominent; antennal prominences dis- 

 tinct, the front concave between them; clypeus somewhat setose, perfectly even 

 and rectilinear at apex, without trace of median tooth or other modification. 

 Antennse barely 3^ as long as the body, slender, the club somewhat gradually 

 formed; second joint feebly obconic, fully % longer than wide, as long as the 

 next two and distinctly thicker ; three to six equal in width and feebly ob- 

 conic in form; third but little longer than wide; fourth and sixth fully }^, the 

 fifth I3, longer than wide; seventh cylindric, as long as the sixth and % vrider, 

 a little longer than wide; eighth longer and nearly % wider than the seventh; 

 distinctly longer than wide, rounded at apex; ninth fully 34 wider than the 

 preceding, conic in apical half, about as long as wide; tenth slightly wider, 

 similar inform, not quite ,^3 wider than long; eleventh much stouter, obliquely 

 pointed, rather shorter than the two preceding. Prothorax strongly conic with 

 feebly arcuate sides, not quite as long as wide, rather small; apex more than 

 3^ as vride as the base, the latter scarcely 14= "wider than the head ; surface per- 

 fectly even, convex and without trace of transverse impression. Elytra short, 

 oval, obtusely ogival behind, barely % longer than wide, much more than 

 twice as long as the prothorax and very nearly twice as wide, widest but 

 slightly before the middle, the sides broadly and evenly arcuate; humeral 

 plica small and moderately elevated, the impression small, basal and incon- 

 spicuous; fovese feeble; subsutural impressions barely traceable and near the 

 base; suture perfectly even, not elevated and without the slightest trace of 

 basal bead. Abdomen with the first segment broadly arcuate and narrowly 

 pale and coriaceous at apex, overlapping the next. Legs long; femora rather 

 strongly clavate, more particularly the anterior; tarsi long and filiform. 

 Length 1.3 mm.; width 0.65 mm.
