BYRRHID^. 117 



(166) 2. * Byrrhus concolor. Concolorate Byrrhus. 



B. ( concolor J niger, pube obscurus, prothorace dislincte canaliculato ; elytris vittis tribus interruptis obsoletis holosericeis atris. 

 Concolorate Byrrhus, black, gloss obscured by pubescence ; prothorax distinctly channelled : elytra with three obsolete 

 interrupted velvetty deep black stripes. 



Length of the body 3 lines. 



Two specimens taken in Lat. 54°. 



DESCRIPTION. 



This nearly resembles B. picipes, but it is much smaller, the prothorax is more distinctly chan- 

 nelled, the elytra have no black band, and the legs are black. 



We have a variety? of this species in Britain, rather larger and not quite so black, with the 

 prothoracic channel less distinct, which Mr. Stephens seems to regard as a variety of B. pilula? but 

 it is only three-fourths of the size of that species, rather wider in proportion to its length, and its 

 pubescence is of a different colour. The only thing in which they agree is in having three inter- 

 rupted velvetty stripes on the elytra, but in B. pilula the first is more distant from the suture than 

 in B. concolor. 



(167) 3. * Byrrhus cyclophorus. Circle-bearing Byrrhus. 



B. ( cyclophorus) ferrugineus, supra niger, pube obscurus, coleoptris circulo pallido subinterrupto inscriptis. 

 Circle-bearing Byrrhus, ferruginous, above black, gloss obscured by pubescence ; coleoptra inscribed with a pale subinter- 

 rupted circle. 



Length of the body 3| lines. 



One specimen only taken. 



DESCRIPTION. 



Body underneath and limbs dull ferruginous, above black with some cinereous hairs intermixed. 

 Antenna? piceous : elytra with two deep black subinterrupted stripes, and inscribed in the middle with 

 traces of a circle formed of pale, or cinereous hairs, common to both. The circle is probably more 

 distinct in recent specimens.
