434 Goleopterological Notices, VII. 



This distinct form somewhat resembles castaneum and triviale^ 

 but is stouter and with the basal segment of the abdomen almost 

 perfectly normal at apex. It differs from both in its large and 

 prominent eyes, obese form and black color, and, from triviale, also 

 in the strong humeral plica and impression. The type is probably 

 a male. 



45. C inerme n. sp. — Stout, highly polished and subimpunctate, piceous- 

 black, the elytra rufous throughout ; legs and antennae pale, testaceous ; pu- 

 bescence rather abundant, pale, coarse, moderately long, even in length and 

 but slightly recurved on the elytra. JTead only moderate in size, strongly 

 transverse, subcircular behind the eyes, which are large and prominent, extend- 

 ing distinctly behind the middle ; front impressed between the rather approxi- 

 mate antennal prominences ; clypeus even, the apical edge perfectly even and 

 very feebly sinuate throughout the width. Antenna a little longer than the- 

 head and prothorax, slender, the club long, narrow and rather gradually 

 formed ; second joint feebly obconic, % longer than wide, as long as the next 

 two and thicker ; three to six equal in width, cylindric and smooth ; three, 

 four and six equal and fully as long as wide, the fifth a little longer ; seventh 

 3^ wider, as long as wide ; eighth nearly ^5 wider than the seventh, almost as 

 long as wide ; ninth and tenth equal, scarcely perceptibly wider than the 

 eighth and nearly as long as wide ; eleventh rather stouter, gradually and 

 very obliquely pointed, very nearly as long as the two preceding. Prothoraur 

 small, conic, the sides feebly arcuate, distinctly shorter than wide ; apex % as 

 wide as the base, the latter }^ wider than the head ; surface feebly and trans- 

 versely biimpressed near the basal margin. Elytra fully % longer than wide, 

 2}4 times as long as the prothorax and nearly twice as wide ; sides evenly 

 arcuate ; humeral plica and adjacent impression long, strong and very con- 

 spicuous ; fovese distinct ; subsutural impressions evident, the suture strongly 

 beaded toward base. Legs slender ; anterior femora rather strongly, the 

 intermediate less and the posterior feebly, clavate ; tarsi slender, the first four 

 joints of the posterior subequal. Length 1.0 mm. ; width 0.45 mm.

The first abdominal segment in the unique type is rather thickly^ 

 but simply pubescent, with the posterior margin broadly arcuate 

 and overlapping the second but without a visible fringe or coria- 

 ceous margin ; the sex is not determinable. 



In its general form, large eyes and small prothorax this species 

 closely resembles testaceipes, differing in the coloration of the 

 body, in its slightly more slender and less incrassate antennal 

 club, and rather sparser and longer elytral vestiture. 



46. C. iiinociiuin n. sp. — Stout polished and impunetate, blackish- 

 piceous, the elytra paler and dark rufo-testaceous throughout ; legs and an- 

 tennse still paler, testaceous ; pubescence rather abundant, pale, coarse, sub-
