It is also a deeper insect than sericeus, and the sides more nearly 

 approach the perpendicular. 



Described by Rosenhauer from three specimens found at 

 Stettin. It has since been found in other parts of Germany, and 

 no doubt is scattered all over the continent. I have not found it 

 in Scotland, but it has been taken by Mr. Guyon near Richmond, 

 and by Dr. Power near London. 



Chaudoir's C. sericatus is said by Kraatz to be only a small 

 variety of this species. I have not seen it, but I have no doubt 

 he is correct. Chaudoir's description contains no character suf- 

 ficient in my view to support the establishment of a new species. 

 His description is as follows : — " C. sericatus, hitherto confounded 

 with C. sericeus. It is constantly three times smaller, more 

 narrowed behind ; the elytra narrower ; the wrinkles above less 

 marked; the antennse less enlarged towards the extremity, the 

 last joints more elongate, the eighth a little narrower, the last 

 less obtuse, and of the colour of the preceding. The breast is 

 less convex ; the colour of the elytra is lighter towards the extre- 

 mity, which is almost ferruginous.

 Long. I- lin. 



The antennas are about the length of the head and 

 thorax, imperceptibly thickened towards the point, fer- 

 ruginous-red ; the seventh joint scarcely broader, but at least 

 twice as long as the preceding, always darker-coloured than the 

 remaining joints; the eighth joint somewhat smaller than the 

 sixth; the ninth, tenth, and the acuminate eleventh tolerably 

 equal in size. The head is blackish-brown, finely punctate, with 

 a grey pubescence. The thorax is blackish-brown, somewhat 

 lighter on the extreme posterior margin, extremely densely and 

 finely granulated, about a fourth broader than long, narrowed 

 in front, moderately rounded on the sides ; the posterior angles 

 are sharp, projecting backwards. The elytra are dark brownish, 

 towards the apex lighter, finely transversely strigose, covered
