than wide, 2^^ times longer than the prothorax and about % wider, narrowly 

 parabolic at apex, widest at basal %] sides evenly arcuate; humeral plica long 

 and strong, the subhumeral impression large and deep ; f ovese large and strong ; 

 subsutural impressions narrow but deep, at basal fifth or sixth, the suture 

 finely beaded basally, the bead expanded at base. Legs moderate; anterior

Ohio ; Illinois. 



As in manj'- other species, the scars left by fallen hairs on the 

 elj^tra are quite distinct, but not exactly in the nature of punc- 

 tures. The abdomen is black with the apex pale. Sexual marks 

 are not discoverable. 



Integrum is a distinct species in the present group because of 

 its larger size, black color and long antennae, but it resembles a 

 small femoral e to some extent. The pronotum seems in certain 

 lights to exhibit feeble traces of the bisected transverse impression 

 so usual in this peculiar group of small obscure species, but it is 

 too faint to be at all decisive. 



36. C. occidensn. sp. — Somewhat stout, polished and subimpunctate, dark 

 piceous, the elytra paler and more rufous ; antennae slightly, the legs much, 

 paler ; pubescence abundant, rather pale, long, somewhat fine and suberect 

 on the elytra. Head slightly wider than long, circularly rounded behind the 

 eyes, which are moderate and but slightly prominent ; antennal tubercles ob- 

 solete, the front not impressed ; clypeus very short, not carinate, asperulate, 

 the apical margin evenly and transversely rectilinear. Antennse but slightly 

 longer than the head and prothorax, slender, the club narrow and rather 

 gradually formed ; second joint but slightly narrower at base, stout, nearly 

 as wide as the first but much shorter, }{ longer than wide, not quite as long 

 as the next two and much thicker ; three to six equal in width ; third dis- 

 tinctly shorter than wide ; fourth as long as wide ; fifth and sixth very slightly 

 longer and equal ; seventh only just visibly wider, fully as long as the sixth 

 and about as long as wide ; eighth % wider than the seventh, rounded at apex, 

 as long as wide ; ninth and tenth subequal in width, neary }{ wider than the 

 eighth, almost as long as wide and }4, wider than long respectively ; eleventh 

 not thicker, elongate, very nearly as long as the two preceding, gradually and 

 acutely conic and oblique from near basal third. Prothorax conic, the sides 

 feebly arcuate, fully as long as wide ; apex % as wide as the base, the latter 

 }4: wider than the head; surface perfectly even and unimpressed. Elytra % 

 longer than wide, twice as long as the prothorax and % wider ; sides broadly 

 and evenly arcuate ; humeral plica narrow, oblique and rather short but strong ; 

 subhumeral impression short and shallow ; inner fovea distinct, the outer very 

 feeble ; subsutural impressions obsolete, the suture not elevated or beaded. 

 Legs well developed, the tarsi slender ; four anterior femora rather strongly, 

 the posterior feebly, clavate. Length 1.2 mm. ; width 0.55 mm.
