ERIIUIININI. 163 



GRYPIDIUS Sch. 



1. G-. equiseti Gyll., Sch. Cure, iii, 314; Curculio eq. Fabr., Ent. Syst. 

 i, 403; Rhynchasnm eq. Fabr., Syst, El. ii, 443, &c. &c. 



A common European species which is is indigenous in Canada, Kansas, 

 and on the north shore of Lake Superior. A Canadian specimen was sent 

 me by Mr. W. Couper, which I determined simply as Qrypidiux, n. sp.?, 

 but by some confusion of labels, in describing the species to which I had 

 given no definite names, he has given the name G. vittatus* to a small 

 species of Sitones, apparently the 8. tibialis of Europe, which occurs in Can- 

 ada and in Hudson Bay Territory, perhaps imported, perhaps indigenous. 



2. G-. brunnirostris Gyll., Sch. Cure, iii, 316; Rhynchanus br. Fabr., 

 Syst. El. ii, 445, &c. 



Two specimens from Oregon do not appear sufficiently distinct from this 

 European species. It is smaller than the preceding, and easily known by 

 the elytral interspaces being even, not tuberculate, and the scales uniform 

 in color. 



ERYCTJS Tournier, Ann. Ent. Belg. xvii. 



This genus contains those species of Erirhinm in which the prosternum 



is deeply emarginate in front, and the postocular lobes broad and distinct. 



The hind tibiae are feebly mucronate, and have in addition two very small 



spines or spurs. 



But two species are known to me, the first of which differs but slightly 



from the European E. mthiops. 



Nearly glabrous, shining ; prothorax sparsely punc- 

 tured 1. morio. 



Mottled with pubescence ; prothorax coarsely, densely 



punctured 2. puncticollis. 



1. E. morio Mann., Bull. Mosc. 18~>3, ii, 240 (ErirMnus.) 

 Alaska, Vancouver Island, Great Slave Lake, Canada. 



2. E. puncticollis n. sp. 



Black, mottled with yellowish pubescence. Head and beak strongly 

 not densely punctured; prothorax as long as wide, sides feebly rounded, 

 more strongly in front, tip slightly impressed on the sides, surface coarsely 

 and densely punctured. Elytra wider than prothorax, humeri rounded, 

 striae with quadrate approximate punctures, interspaces densely punctured, 

 irregularly pubescent, with a more conspicuous sutural transverse spot be- 

 hind the middle. Thighs somewhat clavate, not toothed; front and mid- 

 dle tibiae moderately strongly mucronate, hind pair with a very small mu- 

 cro, and small terminal spurs. Body beneath coarsely and densely punc- 

 tured. Length 5.5-6 mm; .22-. 25 inch. 



Middle and Western States and Lake Superior. Looks like a small 

 Pissodes.
