88 NORTHERN ZOOLOGY. 



DESCRIPTION. 



Body testaceous, hairy. Head oblong, wider than the prothorax, black, thickly punctured ; 

 mandibles and other oral organs dusky-rufous ; antenna? nearly as long as the prothorax, of the same 

 colour but paler at the base and apex : prothorax punctured with a smooth longitudinal intermediate 

 space : elytra thickly punctured : abdomen black, anus testaceous. 



Gravenhorst describes Knoch's 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 colour with 

 the legs. The difference, as they agree in other respects, is probably accidental.

Similar Gyrobypnus, black; prothorax with its dorsal series many-punctured; antennae rufous; elytra and legs yellowish- 

 testaceous, the former blackish at the tip. 



Length of the body 9 lines. 



Two specimens taken in Lat. 54°. 



DESCRIPTION. 



This species approaches very near to G. ochraceus, but it 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 scattered punctures; antenna? and palpi rufous; neck rufo-piceous : prothorax 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 consists 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 blackish : legs yellowish-red. 



6 The species of this family when they sleep, or are in a torpid state, roll themselves up like a serpent. See Stephens' 

 Illustr. Mandib. V, 258.
