ERIRHINIXI. 107 



11. D. hispidus, n. sp. 



Brownish yellow, clothed with coarse yellow hair, slightly mottled near 

 the tips of the elytra, and mixed on the elj'tra with longer stitf suberect 

 bristles. Beak as long as the head and prothorax, finely punctured, with- 

 out stnse and without interantennal fovea. Prothorax strongly punctured, 

 with an indistinct smooth dorsal line ; one-half wider than long, rounded 

 on the sides; suddenly rounded, narrowed, and very feebly constricted near 

 the tip. Elytra oblong elongate, wider than the prothorax, humeri 

 rounded, striae composed of approximate punctures, interspaces wide, fiat, 

 sparsely punctulate. Thighs armed with a small tooth. Length 3.5 mm; 

 .14 inch. 



One specimen. New Mexico. Very similar to the preceding, but suffi- 

 ciently distinct by the suberect bristles of the elytra, the prothorax less 

 constricted at the tip, and the beak without a fovea between the antennae. 



Group II. Desmorhlnes. 



In the genera constituting this group the beak is slender, and separated 

 from the head by a sharply defined transverse line, or constriction. In our 

 genera the claws are connate at base, but as this character is not mentioned 

 in the European genus Sharpia (Tournier, Ann. Ent. Belg. xvii,) and is 

 somewhat variable in Smicronyx, I do not know that it is properly of 

 group value. The mandibles are truncate at tip, and toothed botli on the 

 inner and outer edge as in Rhynchitidte. The prosternum is emarginate 

 in front, and the ventral sutures are very slightly curved at the sides. The 

 antennal grooves descend obliquely and are almost confluent behind.

3. Claws small, frequently connate nearly to the tip SMICRONYX. 



DESMORIS n. g. 



This genus corresponds closely with Erirhinus, except in the differences 

 indicated in the definition of the group, viz., the connate claws, the 

 oblique antennal grooves which are nearly confluent behind, and the beak 

 constricted at base. The second joint of the funicle is as long as the 

 first, but more slender. The thighs are clavate, unarmed. The tibiae 

 slightly mucronate and truncate at tip, nearly as long as the thighs ; tarsi 

 dilated, third joint deeply bilobed, fourth joint long; claws small, connate 

 nearly to the tip. 



The appearance is that of Balaiiinus in miniature, the eyes are rather 

 large and transverse, the sides of the prothorax scarcely lobed, and the 

 prosternum moderately emarginate in front ; the prothorax is rounded on
