impressed and sparse; elytra fully as long as the prothorax, at base 
equal in width to the latter but a little narrower than the head, the sides 
sensibly diverging from the basal angles to the apex and nearly straight, 
slightly longer than wide, the punctures impressed; abdomen broad, 
parallel, as wide as the elytra, minutely and not very closely 
punctulate; legs moderately long and stout. Male unknown, the sixth 
ventral of the female broadly and obtusely lobed at apex. Length

Elytral punctures closer, more distinct and not so obviously seriate; form 
less stout, similar in coloration, the elytra gradually becoming rufous 
in apical third; head much smaller, with the basal angles more broadly 
rounded, equal in width to the prothorax and slightly narrower than the 
elytra, the sides more nearly parallel, similarly punctate; prothorax 
smailer but otherwise nearly similar, the punctures rather stronger 
and less sparse; elytra smaller, subparallel or only slightly broader 
behind, not quite as long as the prothorax and distinctly wider through- 
out, about as long as wide; abdomen as wide as the elytra, finely and 
moderately densely punctulate; legs nearly similar. Male with the 
fourth and fifth ventrals wholly unmodified, the sixth with a very narrow 
and feeble impression along the median line, extending to about apical 
third, the surface thence unmodified to the rectilinearly truncate apex, 
except a very small feeble narrow tumidity at the margin, the edge not 
distinctly modified. Length 10.0 mm.; width 13mm. Illinois, New

5— Form less stout than in the preceding species, rather strongly convex 
and almost exactly parallel, polished, piceous-black in color, the elytra 
rufous, becoming black near the base; legs rufous, the antennae 
piceous; head large, quite distinctly wider than the elytra, slightly 
broader near the base, the basal angles only moderately rounded; 
punctures sparse but deep toward the sides, very remote elsewhere; 
prothorax distinctly narrower than the head, a fourth longer than wide, 
slightly narrowed posteriorly throughout, the angles rounded, the 
punctures sparse, coarse and deep; elytra small, quadrate, subparallel, 
equal in width to the prothorax and much shorter, very coarsely, only 
moderately sparsely and irregularly punctate; abdomen parallel, not. 
quite as wide as the elytral apex, minutely and not very closely punctu- 
late; legs stout. Male unknown; female with the sixth ventral obtusely 
produced and roundly lobed at apex. Length 8.5 mm.; width 1.1 mm.

to serial arrangement, of the abdomen very fine and rather dense; head
