difference of opinion further than to submit the above suggestions 

 for the consideration of the reader. 



I have only to add with reference to this species (C. nigri- 

 cans, Sp.), that the readiest distinction between it and such 

 others (except C. picipes) as are likely to be mistaken for it, is 

 furnished by the longish almost subfiliform ferruginous antennas. 

 In my observations on C. picipes I have already noticed the 

 primd-facie differences existing between it and this species. 



Widely distributed, being found in Scotland and England, 

 France, Germany, and most of Europe, but nowhere common.

This has a considerable resemblance to C. nigri- 

 cans, Spence, in the form of the elytra and antennas, 

 but is smaller, and more continuous in its outline : 

 the hinder angles of the thorax are very slightly acuminate, so 

 slightly as to be scarcely observable except by minute exami- 

 nation : the elytra are indistinctly striated. The antennas are as 

 long as the head and thorax, slightly thickened towards the 

 point, in some individuals a little thicker than in others, reddish 

 brown ; the club usually blackish, but the depth of colour varies. 

 The head and thorax are black, densely and finely punctate, 

 with a fine short yellowish pubescence. The thorax is almost as 

 broad as the elytra, broadest in the middle, straight at the base, 

 the anterior angles rounded, and the posterior angles right-angled 

 at the very angle ; that is, when looked at superficially the angle 

 would appear obtuse, but when examined more carefully there 

 appears a very short space of right angle before the thorax takes 

 its curved outline : the scutellum is proportionally large, and 

 clothed with the same coloured pubescence as the thorax. The 

 elytra are oval, densely and finely punctate, black, clothed with 

 an ashen grey pubescence or bloom indistinctly striated : no yel- 

 low pubescence along the base of the elytra. The legs are reddish 

 brown. 



Its small size, shorter and more thickened antennas, more 

 uniform and less bellied outline distinguish this species from 

 picipes, Fab. Its shorter and more thickened antennas, the 

 yellow pubescence on the thorax and scutellum, want of depres-
