94 THE CANADIAN ENTOMOLOGIST. 



guishing this species from L. punctkolle, the sides of the prothorax are 

 covered with scattered punctures : the tip of the segments of the 

 abdomen, ventral as well as dorsal, is testaceous. [Synonymous with 

 Cryptobium pallipes Grav. — a species taken in Canada.] 



122. Lathrobium [Cryptobium] bicolor Grav. — Length of body 

 4; 3 lines. Taken in Canada by Dr. Bigsby. 



[8S.] Body testaceous, hairy. Head oblong, wider than the pro- 

 thorax, black, thickly punctured ; mandibles and other oral organs dusky- 

 rufous ; antennas nearly as long as the prothorax, of the same color but 

 paler at the base and apex : prothorax punctured with a smooth longi- 

 tudinal intermediate space : elytra thickly punctured : abdomen black, 

 anus testatceous. Gravenhorst describes Knoclis specimen, which also 

 came from North America, as having dark chestnut thorax, elytra and 

 anus ; in the specimen here described they are of the same color with the 

 legs. The difference, as they agree in other respects, is probably acci- 

 dental. [Common in Ontario.] 



123. Gyrohypnus assimilis Kirby.— Length of body 9 lines. Two 

 specimens taken in Lat. 54 . 



This species approaches very near to G. ochraccus, but is more 

 slender in proportion to its length. Body black and glossy. Head 

 rather larger than the thorax, behind the eyes are some rather large scat- 

 tered punctures ; antenna: and palpi rufous ; neck rufo-piceous ; pro- 

 thorax piceous, with a triple series of punctures on each side leaving a 

 discoidal smooth space ; the dorsal ones consist of seven or eight 

 punctures, and the intermediate ones are really a continuation of the 

 dorsal, since by the intervention of a puncture or two both are united so 

 as to form a figure resembling a bishop's crosier ; the lateral series con- 

 sists of a very few points, not easily seen ; near the anterior angle the 

 elytra are scarcely longer than the prothorax, punctured, with some of the 

 punctures arranged in rows and others scattered ; from the humeral to the 

 inner apical angle, they are internally yellowish-red, and externally black- 

 ish : legs yellowish-red. [Previously described by Say — Ent. Works ii. 

 567 — as Xantholinus ccphalus. Taken in Ontario.]
