obconic, }^ longer than wide, as long as the next two and much thicker ; thre& 

 to six equal, cylindric, }^ wider than long; seventh and eighth similar in form, 

 symmetric and trapezoidal from the base, }^ and % wider than the sixth re- 

 spectively and a little more roughly sculptured; ninth % wider and 3^ longer 

 than the eighth, nearly }4 wider than long; tenth similar, though scarcely 

 visibly wider, fully 3^ wider than long, both with a whorl of short stout and 

 porrect setse beyond the middle; eleventh not quite as long as the two preceding, 

 scarcely oblique at apex. Frothorax moderately conic with very slightly ar- 

 cuate sides, about as long as wide; apex % as wide as the base, the latter but 

 slightly more than 3^4 wider than the head; surface perfectly even, without 

 trace of impression. Elytra relatively long, oval, widest at basal %, narrowly 

 obtuse at apex, % longer than wide, distinctly more than twice as long as the- 

 prothorax and nearly ^ wider; sides broadly arcuate; humeral plica minute, 

 the adjacent impression small, basal and inconspicuous; inner fovea deep and 

 distinct, the outer indistinct; subsutural impressions obsolescent, the suture- 

 not elevated. Legs well developed; femora rather strongly clavate, the an- 

 terior only a little more so. Length 1.1-1.2 mm. ; width 0.45 mm.

This is a distinct species and is apparently common and widely 

 diffused in the northern Atlantic States. It resembles fulvum,. 

 but differs in its piceous-black color and much larger size ; from 

 trifidum it may be known by its less ventricose form and much 

 smaller subhumeral impression, and, from d'e&^7^Yans, which it re- 

 sembles most of all, by its larger size, darker color, much longer- 

 elytra, narrower prothorax and shorter but stouter antennal club. 

 The description is drawn from the male, the female however not dif- 

 fering in any external aspect. It is represented hy a large series- 

 and some individuals are pale, probably from immaturity. 



60. C. debilitans n. sp. — Eather narrowly subrhomboid-oval, polished,, 

 impunctate, dark rufo-testaceous, the antennae same; elytra rather paler and 

 brighter red but dusky toward tip ; legs very pale luteo-testaceous ; pubes- 

 cence rather abundant, coarse, pale, short recurved and mingled with some 

 longer and more erect setae on the elytm. Head moderately deyeloped, 

 slightly wider than long, subcircular behind the eyes, which are rather small 

 and scarcely at all prominent; antennal prominences somewhat large and dis.- 

 tinct, separated by a feeble depression; clypeus not carinate, having a few 

 subasperate punctures, the apex finely but distinctly toothed at the middle,, 

 the tooth narrow and acute. Antennae stout, fully as long as the head and. 

 prothorax, the club abrupt, stout and S-jointed; second joint stout, obconic, % 

 longer than wide, as long as the next two and thicker; three to six subequal, 

 nearly }4 wider than long, the inner side of the fourth distinctly shorter than 

 •the outer ; seventh perceptibly wider, transverse ; eighth still a little wider, more 

 pointed within ; five to eight gradually more roughly sculptured ; ninth abruptly-
