triangular ; elytra slightly furrowed with the furrows punctured ; interstices 

 minutely punctured ; anus underneath with two transverse obtuse ridges ; 

 legs rufous. 



[Belongs to Hoplocephala Lap. ; quite common in Canada.] 



[236.] FAMILY BOLITOPHAGID.E. 



321. Bolitophagus cornutus Fabr. — Length of body 5 lines. 

 Taken in Canada by Dr. Bigsby, in a Boletus of the birch, near Lake 

 Huron. [Quite common in old dry fungi on trees and stumps. For 

 description and figures see Say's Amer. Entomology, vol. i, p. 114, plate 

 51. With regard to the orthography of this word, we may mention that 

 the Greek term is Bolites, and the Latin Boletus ; as the termination 

 phagus is Greek the generic name of the insect should be written as 

 above, Bolitophagus, while Boletus is quite correct as applied to the 

 fungus.] 



322. Bolitophagus obcordatus Kirby. — Length of body 6% 

 lines. Taken in Nova Scotia by Capt. Hall. 



Body linear-oblong, pollinose. Head brown-black, subtriangular ; 

 lab rum ciliated with yellow hairs; antennae black-piceous, last joint 

 smaller than the two antecedent ones, which are bigger than the rest : 

 prothorax brown-black, obcordate with a larger anterior sinus for the 

 head ; surface flat, uneven behind from five obtuse ridges, the lateral ones 

 abbreviated, and before from several rounded tubercles : scutellum minute : 

 elytra embrowned with a yellowish tint from lutose scales, anteriorly [237] 

 with three obtuse ridges : the interior one very short ; the intermediate 

 one discoidal, abbreviated at each end ; and the exterior one reaching 

 from the base to the apical tubercles, of which there are two much 

 elevated, the interior one being the largest and highest ; in the interstices 

 there are four rows of deep impressions : the sides of the antepectus are 

 verrucose ; the abdomen is black-brown with lutose sides ; the disk is 

 longitudinally, densely, and thickly wrinkled, and the sides are verrucose ; 

 legs black-brown. 



This species differs from the preceding one in the form of the thorax 

 and the clava of the antennae, and ought perhaps to form a subgenus. 



[Belongs to Nosoderma Esch. : rather rare in Canada.]
