 levigated, narrow spaces: nose anteriorly transverse, reflexed : ])rothora\ 

 with a longitudinal posteriorly abbreviated channel ; sides obtusangular : 

 surface covered, less thickly in the disk, with large, and often conlluent, 

 punctures : scutellum an isosceles triangle, channelled, with a few scattered 

 large punctures on each side : elytra indistinctly furrowed, confluently and 

 irregularly wrinkled, wrinkles marked with shallow indistinct punctures,

 in Nova Scotia by Capt. Hall. 



Near the preceding species, but i)erfectly distinct. Jiody nearly naked, 

 somewhat glossy, of a dark pitch-colour. Nose and front between the 

 eyes with a very deep and large impression, the bed of which is acuducted 

 in circles with a minute puncture in the centre of each ; the rest of the 

 head is confluently punctured ; a])Ove the bed of the antennae the front 

 rises into a rather lofty levigated prominence : the j^rothorax is shaped 

 like that of G. rw^osus, but is rather less obtusangular, the channel is 

 deeper, Avith its sides more elevated, and there are one or two slight 

 impressions between it and the margin ; the punctures on the disk are 

 rather more numerous : the elytra are paler than the rest of the body and 

 a little bronzed, the wrinkles of the surface are more \ermiform than in the 

 species just named, without any punctures, and the appearance of furrows 

 is less distinct : the podex is distinctly punctured and scarcely acuducted ; 

 and the cubit is sinuated rather than dcntated, the three prominences 

 being extremely obtuse. [A description of the male of Osmoderma scabra
