(148) 4. * Oiceoptoma (Necrophila) Canadense. Canada O. Necrophila. 



O. N. ( Canadense J nigrum, prothorace flavo, macula magna discoidali nigra; elytris apice flavis ; epipleura subaurata inlus 



flava. 

 Canada O. Necrophila, black, prothorax yellow with a large black discoidal spot; elytra yellow at the tip; epipleura golden- 

 bronzed, internally yellow. 



Length of the body 7 lines. 



Taken in dead fish on the shores of Lake Huron in Canada, by Dr. Bigsby. 



DESCRIPTION. 



This species approaches near to O. N. Americanum, but it is smaller, the frontal impression is 

 deeper and oblong; the discoidal spot of the prothorax is much larger, extending from the anterior 

 to the posterior margin, it is scarcely at all lobed, and only the punctures of its posterior part exhibit 

 the appearance of angular scratches : the elytra are dirty-yellow at the apex, and the yellow occupies 

 a much greater portion of the extremity than in the two preceding species, they are not acuminate 

 at the tip, but have a very slight tendency to a sinus ; the epipleura in colour resembles that of 

 O. N. Americanum, but is less brilliant.
