54 THE CANADIAN ENTOMOLOGIST. 
MA 
This species is the American representative of 7: caraboides from which 
it principally differs in being larger, with the frontal impressions more 
distinct ; the stalk of the antennæ much slenderer, and the knob thicker : 
the prothorax not so narrow and constricted at the base, and the elytra 
slightly furrowed. [“The description of this species is so imperfect that it » 
cannot be identified ”(Le Conte)]. 
[167.] FAMILY CERAMBYCIDÆ. 
221. MONOCHAMUS RESUTOR Azrby.—Length of body 1034 lines. 
Frequently taken in Lat. 65°. 
[Synonymous with Afonohammus scutellatus Say—a very abundant spe- 
cies in many parts of Canada. For description of this well-known insect, 
vide Say’s Ent. Works, 1. 192.] 
[168.] 222. MonocHamMus conrusor X%rby.—Length of the body 
t inch and 134 lines. Taken in Nova Scotia by Dr. Mac Culloch, in 
Canada by Dr. Bigsby, in Massachusetts by Mr. Drake. 
Body linear, elongate, black, covered with white or cinereous decum- 
bent hairs, but so as to let the black appear in confused spots and reticu- 
lations. Labrum rather long, fringed anteriorly with ferruginous hairs ; 
maxillary palpi long ; rhinarium broad, rufous ; antennæ testaceous with 
the redness obscured by decumbent cinerous hairs, but the scape and 
pedicel are black ; the antennz of the female are something longer than 
the body ; those of the male are twice its length : the spines of the pre- 
thorax are stout, covered thickly with white hairs, and dotted posteriorly 
with black ; in the disk is a central oblong impression : scutellum thickly 
covered with white decumbent hairs, with a black longitudinal line: the 
ground colour of the elytra is testaceous which is more or less obscured 
and clouded by white decumbent hairs, besides there are.several black 
dots and oblong spots produced by erect hairs ; at the base of the elytra, 
especially on the projecting shoulders, are numerous round elevated 
smooth little spaces, and their whole surface is covered with scattered 
minute punctures. 
N. B.—In the male the black spots and dots of the elytra are fainter, 
and sometimes nearly obliterated. [The synonyms of this species are 
so much confused that Kirby’s specific name may certainly be considered 
a most appropriate one, if it is allowed to stand. The insect here de 
scribed is apparently identical with A/onohammus notatus Drury, and JZ. 
titillator Harris ; according to the rules of priority, it should, therefore, 
have the former name. It is a very common species in the pine forests 
of this country, especially in timber that has been left standing after a fire
