base, scarcely more than % longer than wide, not as lonj^ as the next two and 

 very decidedly thicker ; three to six equal in width, cylindric ; third quad- 

 rate ; fourth and sixth %, the fifth nearly y^, longer than wide; seventh almost 

 3^ wider than the sixth, fully as long as wide, finely beaded at base ; eighth 

 % wider than the seventh, fully as long as wide ; ninth and tenth subequal 

 and but little wider, fully as long as wide ; eleventh long, obliquely and 

 gradually pointed, rather thicker but not quite as long as the two preceding. 

 Prothorax rather small, nearly as long as wide, strongly conic with distinctly 

 arcuate sides ; apex narrow, not more than 3^ as wide as the base, the latter 

 nearly }'.^ wider than the head ; surface distinctly biimpressed transversely 

 near the base. Elytra % longer than wide, 2% times as long as the prothorax 

 and neaiily % wider, widest near basal %, acutely rounded behind, the sides 

 broadly arcuate ; humeral plica rather long and strong, the impression dis- 

 tinct ; fovese deep ; subsutural impressions narrow and feeble, the suture finely 

 and not very strongly beaded basally, the bead feebly expanding at base. Ab- 

 domen with the first segment widely overlapping the next, and with a very 

 minutely fringed coriaceous hind margin. Legs long, the femora all strongly 

 clavate, the posterior only slightly less so. Length 1.6 mm. ; width 0.68 mm. 



Michigan. 



The description is drawn from the female, whicli is the only 

 sex which I have been able to examine ; the species is rather 

 closely allied to atrum, but is notably narrower in the body, 

 with ranch less developed humeral plica and subhumeral impres- 

 sion, longer antennae with less abruptly formed club, much paler 

 legs and other characters of minor weight. The type was com- 

 municated by Mr. J. Croissandeau. 



80. C. paganuni n. sp. — Moderately stout and ventricose, polished, im- 

 punctate, black throughout, the elytra with a feeble rufo-piceous tinge, the 

 legs and antennae pale rufo-testaceous ; pubescence rather abundant, erect, 

 coarse, pale and conspicuous on the elytra. Kead quite distinctly wider than 

 long, subcircular behind, the eyes rather large, convex and prominent ; an- 

 tennal prominences small but distinct, the front concave ; clypeus with strongly 

 setigerous punctures, the apical margin rectilinear but interrupted at the middle 

 by a minute and very broady rounded feeble projection. Antennse moderate, 

 not quite % ^s long as the body, slender, the club distinct but gradual ; sec- 

 ond joint long, very feebly obconic, % longer than wide, fully as long as the 

 next two and but slightly thicker ; three to five subequal, cylindric, rather 

 longer than wide ; sixth only just visibly wider and not quite as long as 

 wide ; seventh }^ wider, 3^^ wider than long and more asperate ; eighth 

 scarcely }^ thicker, not quite as long-as wide ; ninth and tenth equal in vndth 

 and }^ wider than the eighth, 34 and about % wider than long respect- 

 ively ; eleventh a little thicker, obliquely and gradually pointed, somewhat 

 longer than the two preceding. Prothorax moderately large, nearly as long as 

 wide ; apex nearly ^ as wide as the base, the latter scarcely 34 wider than the
