1. C ainplicollis Motsch. — Moderately convex, lead black, opaque, clothed 

 above with fine cinereous pubescence and short suberect bristles, directed forward 

 on the head and basal half of the thorax, backward on the anterior part of the 

 thorax and on the elytra. Antennje black, serrate, about as long as the head and 

 thorax in the %, a very little shorter and more slender in the 9' second joint 

 more than one-half as long as the third, which and the following are about equal 

 in length ; third to sixth broader, seventh to eleventh gradually more slender, 

 the last elongate oval, constricted at tip. Head densely and strongly punctulate, 

 and with sparser coarser punctures, frontal margin elevated and broadly rounded, 

 and with near each end a short oblique carina directed towards the upper part 

 of the eye. Thorax usually broader than long, densely strongly punctulate, 

 with sparser punctures regularly intermixed, longitudinally impressed at middle, 

 sides strongly arcuate, more narrowed in front than behind, hind angles ob- 

 liquely truncate above, produced beneath, the carina not joining the submarginal 

 line behind, the basal lobe more or less distinctly tridentate, plicae long. Elytra 

 feebly rounded at sides or subparallel, strife moderately impressed, punctured ; 

 intervals slightly convex, punctulate and transversely wrinkled. Jiody beneath 

 clothed with cinereous pubescence, rather closely and strongly punctulate, with 

 the coarser punctures everywhere evident, but a little less marked on the pro- 

 pleursB. Intercoxal process of prosternum long, rather narrow, acute and feebly 

 ascending, the marginal lines reaching the apex. The submarginal lines of the 

 prothorax are nearly straight, sharply elevated internally, or cariniform, im- 

 pressed exteriorly and reaching beyond the middle, base inside the angle not, or 

 sctircely sinuate. Hind coxal plates diUited behind outwardly with the free 

 angle rounded. Legs black, middle and hind tarsi nearly as long as the tibiae, 

 sleuder, jmbescent and spinose, the first joint of the middle and hind tarsi longer 

 than the last, the second about equal to it, third and fourth gradually shorter ; 

 the anterior tarsi are shorter, the first joint about equal to the last, second, third 

 and fourth gradually shorter ; claws moderate. Length .26 -.27 inch ; 6.2-6.5 mm.
