122. Lathroi;ium [Cryptobilmj dicoj.or (y /-(?<•. — Length of body 

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



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

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

 rufous ; antenna; 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 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 color with the 

 legs. The difference, as they agree in other respects, is [n-obably acci- 

 dental. [Common in Ontario.] 



123. GvROHYPNUS ASSiMi LIS A7/7vr. -Length of liody 9 lines. 1 \so 

 sjtecimens taken in Lat. 54"". 



This species approaches very near to G'. ih/irdcats, but is more 

 slender in proportion to its length. 13ody black and glossy. Head 

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

 tered punctures ; antennce and pal].>i rufous ; neck rufo-piceous ; pro- 

 thorax jjiceous, with a trijjle series <.)f j»vuictures on each side leaving a 

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

 punctures, and the interniiidiate ones are really a coniinuati(3n of the 

 dorsal, since by the intervention K^i a puncture or two both arc united so 

 as to form a figure resembling a bisho[)"s crosier ; the lateral series con- 

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

 el\tra are scarcely longer than the prothorax, punctured, widi some of the 

 jjunctures 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 Xantholiniis ccphalus. Taken in Oiitario. ]

 One specimen taken in Lat. 65 '. 



Body piceous, glossy, naked, rather grossly j^unciurcd. Head nar- 

 rower than the ))rothorax ; eyes prominent ; antennae rather longer than 

 the heail and thorax, dusky-rufous : prothorax rather wider than long, 

 lateral margin somewhat dilated ; near it, and partly in it, is a deej) 

 punctiform impression, and above the scutellum another obsolete one : 

 elytra something wider than the i>rothorax, and nearly as long as the 

 abdomen, paler at their apex : legs dusky-rufous. This species is re- 

 lated to O. ftituifi, but it is more grossly [junctured, the lateral margin
