162 CURCULIONID^. [LeConte. 



Group I. Erirhini. 



The species have the beak long, usually slender, the mandibles with two 

 sharp teeth at the end ; the inferior cusp in Erycus comes to the outer mar- 

 gin, and is not very prominent, but thus shows a tendency to assume 

 the position which it has in the next group. The antennal grooves 

 are directed against the eyes, and do not converge beneath. The scape 

 nearly or quite attains the eyes, and the first, and usually the second 

 joint of the funicle are longer than the others. The mesosternum is as long 

 as the first ventral; the legs are slender, tibiae truncate at tip, and feebly 

 mucronate; the tarsi are spongy beneath, with the third joint dilated and 

 bilobed; last joint long, claws rather strong, simple, divergent. 



This group recedes in the direction of the Phytonomini and Hylobiini*

This genus bears a strong resemblance to Erycus, but differs in having 

 the beak rather less slender, and the antennie inserted very near the tip; 

 tlie second joint of the funicle is shorter than the first, though longer than 

 the third. The prosternum is stronglj^ emarginate in front, and the post- 

 ocular lobes are bi'oad. The thighs are unarmed, the tibiae straight, 

 .strongly pubescent, truncate at tip, and scarcely mucronate ; the hind pair 

 hiive two small terminal spines or spurs, as mentioned by Tournier.f

Lake Superior; Ulke. My specimen agrees so closely with the descrip- 

 tion and figure (DuVal, Gen. Col. Eur. iv. pi. 13, f. 58), that I do not ven-^ 

 ture to separate it. Opaque, black, slightly mottled with spots of very fine 

 pubescence ; head and beak very densely punctured. Prothorax a little 

 wider than long, rather small, rounded on the sides, narrower in front, and 

 very slightlj- constricted; very densely punctured. Elytra one-third wider 

 than the prothorax, oblong, humeri rounded, striae deep, catenate with dis- 

 tant punctures; interspaces wide, flat, finely and densely rugose and sub- 

 granulate. Beneath densely punctured, less opaque. Length, 5.3 mm; 

 .21 inch. 



* The following species do not belong to this tribe : Erirhinus ephippiatus Say, 

 has the thighs not toothed, and the claws broadly appendiculate; it indicates 

 a new genus Alycaoi Anthonomini. Erirhinus juniperinus Sanborn, is an Aniho- 

 nomus. Erirhinus lutulentus and rutilus Boh., Sch. Cure, vii, 2d, 16-3 and 167 not 

 identified.
