triangular ; elytra slightly furrowed with the furrows punctured ; interstices 
minutely punctured ; anus underneath with two transverse obtuse ridges ; 
legs rufous. 
[Belongs to Æoplocephala Lap. ; quite common in Canada. | 
[236.] FAMILY BOLITOPHAGIDÆ. 
321. BOLITOPHAGUS CORNUTUS Zabr.—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 Boites, and the Latin Boletus; as the termination 
phagus is Greek the generic name of the insect should be written as 
above, Lolitophagus, while Boletus is quite correct as applied to the 
fungus. | 
322.  BOLITOPHAGUS OBCORDATUS Azrby.—Length of body 6% 
lines. Taken in Nova Scotia by Capt. Hall. 
Body linear-oblong, pollinose. Head brown-black, subtriangular ; 
labrum 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 Vosoderma Esch. : rather rare in Canada. |
