cylindrical : the prothorax at the three posterior angles has three white

 [Taken in Canada.] 



[115.] 163. I)er.me>tes lardarius //««. — Taken in Nova Scotia by 

 Capt. Hall ; in Massachusetts by Mr. Drake. Latreille observes that 

 this insect is found in every quarter of the old world. [We may add, in 

 the new as well. It is a great pest to collectors m Canada.] 



164. Derme-stes dissector Kirby. — Length of body 3V3 lines. 

 Taken by Dr. Bigsby in Canada. [Apparently identical with Say's Z>. 

 nubilus (t!nt. Works, i. p. 300), which differs little, if at all, from D. 

 camnus Germ. Not uncommon in Canada.] 



[116.] 165. Byrrhis picipes Kirby. — Length of body 35 lines. 

 A single specimen taken in Lat. 54^ 



Body black, covered with short decumbent hairs. Scutellum velvetty- 

 black : elytra with a pair of deep black interrupted stripes terminating in 

 a transverse abbreviated posterior band of the same colour : legs piceous. 

 [As this specific name is preoccupied, Le Conte has named the species 

 B. Kirbyi. It is taken in Canada from Quebec to the north shore of 

 Lake Superior.] 



[117.] i66. BvRRHUs concolor Kirby. — Length of body 3 lines. 

 Two specimens taken in Lai. 54'. 



This nearly resembles B. picipes. but it i.s much smaller, the prothorax 

 is more distinctly channelled, the elytra have no black band, and the legs 

 are black. [Supposed by Le Conte to be a variety of Cytilus varius Fab.] 



167. BvRRHUs CYLLOPHORUs Kirby. — Length of body 35^ lines. 

 One specimen only taken. 



Body underneath and limbs dull ferruginous, above black with some 

 cinereous hairs intermi.xed. Antennae piceous : elytra with two deep 

 black sub-interrupted 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. [Taken at Grimsby, Ont., 

 by Mr. Petti t, and at Toronto by Mr. Couper ; north shore of Lake 

 Superior by Agassiz's Expedition.] 



[118. J 168. Byrrhus varus Fabr. — Length of body 2^ lines. 

 Several specimens taken in the journey from New York to Cumberland-
