144 SUBFAMILY X. CURCULIONIN.E. 



scribed from "Amer. Bor.," and cited as a Canadian species by Couper and 

 other authors of a generation ago. LeConte referred to this species Kan- 

 sas specimens with erect elytral setae; possibly, therefore, the eastern 

 records were based on the species now called hispidula. 



Tribe II. ALOPHINI. 



To this tribe belong a small group of genera having the man- 

 dibles flat and punctured on the outer side, pincer-shaped, their 

 tips emarginate; beak rather stout, as long as thorax, expanded 

 each side at tip and usually with a median groove along its upper 

 surface; scape long, fuuicle 7 -jointed, club oval, pointed, annu- 

 lated ; eyes transverse, narrowed below, finely granulated ; thorax 

 usually with distinct postocular lobes; elytra oval, convex, with- 

 out humeral angles, strongly deflexed behind the middle; front 

 coxa3 contiguous, prominent; first, second and fifth ventral seg- 

 ments long, third and fourth united, equal to or longer than 

 either first or second ; tarsi dilated, claws simple. Two of the 

 six genera comprising the tribe are represented in our territory. 



KKY TO EASTERN GENERA OF ALOPHINI. 



a. Beak finely channelled; upper surface of body clothed with hairs, not 

 at all scaly; tarsi brush-like beneath. I. TRICHALOPHUS. 



aa. Beak not channelled or carinate above; body covered with scales in- 

 termixed with bristles on the elytra. II. LEPIDOPHORUS. 



I. TRICHALOPHUS Lee., 1876. (Gr., "hairy"-f "without crests.") 



Bather large, oblong-oval species having the beak \vith a single 

 groove above and on each side; second joint of funicle slightly 

 longer than first; head and thorax densely punctured; elytral 

 striae almost obsolete. One of the six known species occurs with 

 us, the other five occurring in the Northwestern United States 

 and Canada. 



182 (8355). TRICHAXOPHUS ALTERNATUS Say, 1831, 10; ibid. I, 271. 



Oblong-oval. Piceous black, rather thickly clothed with prostrate 

 brown and white hairs, the latter forming a faint line each side of thorax 

 and numerous small spots alternating with brown ones on elytra, the 

 most prominent of which is near the apex of each elytron. Beak almost 

 straight, rugosely punctate, clothed with small, hair-like fuscous scales. 

 Thorax slightly wider than long, feebly impressed near apex, disc coarsely 

 and closely punctate, obsoletely carinate on median third. Elytral inter- 

 vals Wide, flat, densely and finely punctured. Length 9 11 mm. 



Known from Ontario. Canada, Lake Superior and the North- 

 west.
