 hind; base broadly sinuate, the apex much more narrowly subtruncate; sides 

 evenly arcuate; humeri distinctly exposed at base; punctures fine and dense.

The narrower form, still smaller size and relatively- larger head 

 will readily distinguish this species from the preceding. In the 

 male the anterior tibiit are bent toward apex, the fifth ventral 

 feebly sinuato-truncate at apex but not otherwise modified, the 

 genital segment thin, broad, truncate at apex, strongly and trans- 

 versely impressed, the surface bent downward toward apex 

 throughout ; the copulatory spicule is abruptly narrowed near the 

 apex and produced in a short slender process, which is gradually 

 bent upward and not compressed ; the efferent duct beneath the 

 spicule is broad, flat, transversely truncate at tip, bent first down- 

 wai'd then upward and projects in the t3-pe specimen far beyond 

 the corneous spicule.

Elongate, subparallel, moderately stout and convex, shining, 

 dark rufo-testaceous, the under surface of the hind body black; 

 elytra paler and more flavate, with a broad median black ftiscia 

 which sometimes covers almost the entire disk ; pubescence coarse 

 and decumbent but rather short and sparse. Head triangular, 

 wider than long, truncate, coarseh' and not densely tuberculose, 

 the fine punctures each near a tubercle ; median smooth line nar- 

 row and irregular ; ej-es moderatel}' large ; antennte slender, the 

 outer joints submoniliform, three-fourths longer than the head. 

 Prothorax transversely' trapezoidal, just A'isibly wider than the 

 head, the sides convergent and feebly arcuate from near the trans- 

 versely arcuate apex to the basal margin, thence parallel to the 

 base; disk broadly impressed along the median line, coarsely tu- 

 berculate, the fine punctures each near the posterior extremity of 

 a tubercle. Elytra oblong, two-thirds longer than wide, one-half 

 wider than the prothorax, semi-circularly rounded behind, paral- 

 lel and feebh^ arcuate at the sides ; humeri widely' exposed at 

 base; disk with a feeble intra-humeral and more distinct post-
