[LeConte. 



1. E. echidna, n. sp. 



Oval, not convex, narrowed before and behind, covered with a crust of 

 dirt-colored scales, and with long stiff bristles, less evident on the under 

 surface. Prothorax very uneven; elytra with narrow striae, interspaces 

 wide. Outer part of beak naked, brown, shining, somewhat punctured. 

 Length 2-5 mm.; .10 inch. 



Illinois; one specimen given by Dr. S. V- Summers to Dr. Horn. 



PLOCAMUS n. g. 



Of the form of an elongate Centrinus, clothed with a dense crust of gray 

 scales, with short erect bristles intermixed. Beak as long as the head and 

 prothorax, slender, curved, slightly and gradually thickened behind the 

 antennae, which are inserted one-third of the length from the base; eyes 

 transverse, finely granulated. Antennae similar to those of Euchcete*, but 

 with the funicle shorter and less slender; second joint not longer than third. 

 Head less immersed in the prothorax; the latter is scarcely rounded on the 

 sides, which are oblique, very strongly constricted in front, without post- 

 ocular lobes, slightly bisinuate at base, scutellar lobe indented, and slightly 

 emargina'e. Scutellum rather larger than usual. Elytra a little wider than 

 the prothorax, sides parallel, regularly rounded at tip. Under surface and 

 legs, exactly as in Euchwtes. 



P. hispidulus, n. sp. 



Elongate, blackish brown, densely clothed with a crust of gray scales, 

 with short, erect pale bristles. Beak brown, naked beyond the antennae, 

 which are also brown. Prothorax somewhat uneven, deeply and densely 

 punctured. Elytra somewhat clouded with darker gray, especially by a 

 transverse spot about the middle; striae deep, interspaces not wide, slightly 

 convex; humeri oblique, ob'use, scarcely rounded Length 2 mm. ; .08. 



Southern States. I am indebted to Mr. Ulke for several specimens found 

 at Washington, D. C. I have adopted the name under which it appears in 

 Dej;.an's Catalogue. 



Tribe XX. 



The sub-family of genuine Curculionidcv fitly closes with a very anoma- 

 lous insect, which while having relations with several of the earlier tribes, 

 exhibits in addition a character which is otherwise seen in one of the sub- 

 families of the CalandridoB. The eyes, namely, are very large, transverse, 

 and coarsely granulated; they are widely separated above, but are nearly 

 contiguous beneath. It follows from this that the antennae in repose must 

 be received in front of the eyes, which therefore form as it were a collar be- 

 neath; and the antennal grooves, which are deep and oblique, attaining the 

 eyes near the upper end, are suddenly and acutely flexed beneath, forming 

 a deep, transverse excavation in front of the eyes. 



The beak is shorter than the prothorax, stout, somewhat flattened, a little 

 wider at tip than base; the mandibles are rather flattened, acute at, tip, 

 toothed on the inner side. The gular peduncle is small and narrow, emar-
