sides roinukd, the greatest width at the middle ; very {2:encrally 

 with two or tlirec depressiojis ou tlie ilisk ; posterior angles with 

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

 luartcin a|)pear to be visibly sinuate on both sides. Elytra 

 blackish brown, sometimes paler, elo/igate-oval, somewhat con- 

 vex, densely and finely jnmctatc ; faintly striate, the stria? per- 

 ceptible towards the extremity, effaced in front. Under side 

 bhxck ; 1cj:;s reddish brown, thighs blackish. 



Kraatz gives the following remarks on the larger and smaller 

 varieties which have been described under the names of C. lon- 

 gipennis, Chaud., and C fuLiginosus, Erichs. ; 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 

 antennae of these larger exam])lcs are somewhat more elongate 

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

 females are also somewhat less stout, which makes them when 

 taken as a whole look umch longer than the antennae 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 striic of the elytra are more feebly marked in 

 this than in the other kind. Such examples arc 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. nigricans, Spcnce.^' 



The description by M. Chaudoir to which M. Kraatz refers is 

 as follows, viz. : — 



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

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

 flatter, longer : antenna; more slender, last joint of these smaller 

 and more pointed. 



" A male, found at Kiew in the garden of the town under dry 

 leaves, in the beginning of Septcmberf." 



As to YiXich^on' a fuliginjjsus, M. Kraatz goes on — 



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

 C. fuliginosus by Erichson, according to two specimens left by 

 Dr. Mcuer to the Royal ]\Iuseum (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 aj)pearance from tlie full- 

 coloured specimens. If we compare more minutely Erichson^s 

 clear descri|)tion8 of both species, we find, besides an agreement
