sides rounded, the greatest width at the middle ; very generally 

 with two or three depressions on the disk ; posterior angles with 

 a point, projecting a little behind, which makes the posterior 

 margin appear to be visibly sinuate on both sides. Elytra 

 blackish brown, sometimes paler, elongate-oyal, somewhat con- 

 vex, densely and finely punctate ; faintly sti-iate, the striae per- 

 ceptible towards the extremity, effaced in front. Under side 

 black ; legs reddish brown, thighs blackish. 

 '^\vfcaatz gives the following remarks on the larger and smaller 

 varieties which have been described under the names of C, Ion- 

 gipennis, Chaud., and C. fuliginosus, Erich s. ; viz. — 



"A. Larger, for the most part female specimens, differ from 

 the smaller males in many particulars, so that one may easily be 

 led to suppose them distinct species. In the first place, the 

 antennse of these larger examples are somewhat more elongate 

 than those of the smaller specimens, and when they belong to 

 females are also somewhat less stout, which makes them when 

 taken as a whole look much longer than the antennse of the 

 smaller individuals. Then the elytra are more bellied out, so 

 that the whole animal assumes a more convex appearance ; at the 

 same time also the strise of the elytra are more feebly marked in 

 this than in the other kind. Such examples are generally found 

 along with the rest, but not frequently, and are not of the typical 

 form. If there had not been laid before me by himself one of the 

 original typical examples from Germar's fine collection, it would 

 not have been possible for me, from the short and imperfect de- 

 scription which Chaudoir gives of his C. longipennis^ , to perceive 

 in it the just- described variety of C. nigi^icans, Spence.^^ 'tfiioj 



The description byi M* Chaudoir to .which iM. Kraatz refers is 

 as follows, viz. i-rta lonoj -obTg fiili no 



" Near the umbrinus, a little larger, form more elongate : thorax 

 broader, more rounded on the sides : elytra less swollen out, 

 flatter, longer : antennse more slender, last joint of these smaller 

 and more pointed.

"B. The type of C. nigricans, sp., is the one described as 

 C fuliginosus by Erichson, according to two specimens left by 

 Dr. Meuer to the Royal Museum (of Berlin). Those specimens 

 which are in the Royal Museum as C. nigricans are not fully 

 coloured, and, when we have only a few specimens for compa- 

 rison, such have altogether a different appearance from the full- 

 coloured sj)ecimens. If we compare more minutely Erichson's 

 ^airldescriptions of both species, we fin d^ besides an agreement
