interspaces. In some specimens the elytra are uniformly clothed, without 

 any denuded spots. Tlie second joint of the funicle is as long as the first, 

 hut more slender. The elytra are conjointly rounded at tip, and the 

 pygidium is not visible. The prosternum is transversely impressed and 

 flattened, as in the preceding species, not armed in the (j^; the emargina- 

 tion in front of the mesosternum is wide and deep, limited by sharp 

 angles. The metatlioracic episterna are wide, and the fifth ven'.ral but 

 little longer than the fourth.

 Are unlvuown to me. I think it possible that the latter may be a large 

 variety of penicelhts; the former is perhaps the 9 of the next. 



3. C laevirostris, n. sp. 



Black, densely clotlied with small gray scales, which are narrower but not 

 hair-like upon the upper surface. Beak as long as the head and prothorax, 

 slender, curved, opaque, smooth, slightly punctured and pubescent near the 

 base; head fee')ly punctulate. Protliorax not wader than long, rapidly 

 narrovved from the base, strongly rounded on the sides, very strongly 

 tubularly constricted near the tip, bisinuate at base; scutellar lobe slightly 

 emarginate; surface densely rather finely punctured, scales not directed 

 transversely; dorsal line smooth, slightly elevated. Elj^tra conjointly 

 rounded at tip, pygidium slightly visible (only in r^t); striae deep but not 

 broad, interspaces flat, densely punctured ; suture and alternate spaces 

 clotlied with paler scales. Anteunai with the second joint of funicle two- 

 thirds as long as the first. Side pieces of metas'ernum wide; fiftli ventral 

 nearly as long as third and fourth united. Hind margin of prothc,-ax 

 beneath narrowly emarginate. Length 6.2 mm.; .2.3 inch.

Missouri, one specimen. This is the largest species in our fauna, and 

 corresponds in size with C. pistor and dilectus; I do not feel disposed how- 

 ever, to refer it to either of them. 



4. O. punctirostris, n. sp. 



This species corresponds in all respects with C. loB/virostris, except that 

 the scales are of a uniform pale gray; the beak is stouter, especially at the 

 base, coarsely punctured even at the tip, with a small smooth space at the 

 base, and tlie punctures of the prothorax though dense, are somewhat 

 larger. Lenglli 6.2 mm ; .25 iiicli.

5. C. striatirostris, n. sp. 



More robust than the two jireceding species. Beak not very slender,
