B. Beak stout, claws simple; eyes nearly entirely ex- 

 posed. 



Black, clothed with fine brown pubescence; an- 

 tennae and legs dark testaceous 2. cretura. 



Brown, with some small white spots 3. obscurus. 



1. O. Zimmennanni Gyll., Sch. Cure, iv, 580. 



South Carolina and Georgia. The beak in this species is nearly as long 

 as the prothorax, and is only about one-quarter as wide as its length. The 

 supraocular ridges are less developed than in tlie two other species. The 

 postocular lobes are very broad and nearly conceal the eyes in repose. 



2. C. cretura. Cm-culio crekiraHerhst, Kafer, vii, 70; pi. 100, f. 5; Ceu-

 Journ. Ac. Nat. Sc. Phil, iii, 310; ed. Lee. ii, 173. Phi/tobius 4-spin. Gyll.. 

 Sch. Crirc. iii, 463. 



Broadly ovate, black, above thinly clothed with brown pubescence, be- 

 neath at the sides covered with pale brown scales, extending upon the sides 

 of the prothorax. Head punctured, broadly impx'essed between the eyes; 

 finely carinate behind, supraorbital ridges strong; beak rather stout, curved, 

 as long as the head, finely punctured. Prothorax wider than long, strongly 

 narrowed in front, densely punctured, middle of base deeply impressed; 

 the two apical denticles are acute and distant; the posterior or lateral tu- 

 bercles are also large and acute. Elytra with deep striie, which are punc- 

 tured at the bottom; interspaces not much wider than the striae near the 

 suture, but becoming wider externally, densely rugose. Beneath densely 

 coarsely punctured, antennae and legs brown; claws not toothed. Length 

 2.8 mm. ; .11 inch. 



Middle and Western States. Of the same size, form and sculpture as C. 

 Zimmennanni, but quite distinct by the shorter beak, simple claws, unva- 

 riegated pubescence, and not channeled prothorax. It is perhaps worthy 

 of being separated with the next species, as a distinct genus, on account of 

 the eyes being almost entirely exposed in repose, while in C. Zimmerman- 

 ni they are nearly covered. 



3. C. obscurus, n. sp. 



Broadly oval, reddish brown, head darker, strongly punctured, deeply 

 impressed; supraorbital ridges strong; beak very stout, not longer than the 

 head, more finely punctured. Prothorax wider than long, much narrowQd 

 in front, coarsely punctured, channeled; apical denticles acute, distant, 

 posterior tubercles acute. Elytra with a few small spots of white hairs; 

 striae deep, strongly punctured; interspaces but little wider, convex, finely 

 rugose and finely scaly. Beneath coarsely punctured, clothed with pale 

 scales. Antennae and legs testaceous, claws not toothed. Length 2.8 mm. ; 

 .11 inch. 



Florida; Dr. E. Brendel, and Messrs. Hubbard and Schwarz. Of the 

 same form and size as the preceding, but with shorter and stouter l)eak: 

 more coarsely punctured, and rather deeply channeled prothorax.
