'New Mexico, Fendler. one specimen. Oval subquadrate, black, scarcely 

 -shining, glabrous. Head sparsely punc ulate; beak punctulate, as long as 

 the pro thorax, not stout, regularly and s rongly curved, frontal constriction 

 tfeeble. Prothorax suddenly narrowed, rounded on tlie sides in front, and 

 constricted at the sides near the tip; punctures distant on the disc, more 

 dense towards the sides; smooth dorsal line very dis inct. Elytra with 

 d 'ep striae, interspaces fla ! , ra her wide, wi h rows of shallow dis ant punc- 

 tures, which are more evid nt than usual. Pros ernum very wide between 

 -the coxae, coarsely and spars 'ly punctured, broadly concave in front, with 

 two small impressions. L 'iigth 3.3 mm. ; .13 inc'i.

;&in Francisco, Cal. ; one specimen. A small, shining black species of 

 HI arrow form, resembling in this resp 'C L the nex', as well as Btiris sparsa, 

 mid Pseudoburis anyusta. From the last two it is easily distinguished by 

 ; the generic characters; from 0. macra i: is readily kn nvn by the more dis- 

 <tan* fron 1 coxae. The pros ernum is as wide as in the two preceding spe- 

 cies, flat and coarsely punctured, wLhout impressions. The third joint of 

 the tarsi is less broadly dilated. 



Head dull, feebly punc ulate; beak as long as the prothorax, not stout, 

 ,'rugosely puncaired, regularly carved, frontal constriction faint. Protho- 

 )rax scarcely longer than wide, sid.-s rounded in front, and scarcely con- 

 stricted; punctures strong, and dens?, without smooth dorsal line. Elytra 

 with rathe'r narrow striae, interspaces flat, each with a row of small distant 

 ^punctures. Length 2.5 mm.; .10 inch. 



*6. O. cribrata, n. sp. 



; Elongate, brownish black, shining, sparsely clothed with rather coarse 

 white reclinate hairs. 'Head smooth, beak short, not longer than the pro- 

 thorax, stout, curved, punctured, strongly constricted at base. Prothorax 

 quadrate, wider than long; sides parallel, suddenly narrowed and rounded 

 .near the tip; very coarsely punctured, and smooth dorsal line narrow, but 

 distinct. Elytra a little wider than the prothorax, sides parallel, rounded 

 -at the tip, striae deep, interspaces narrow, each with a row of rather distant 

 small punctures, from which proceed white hairs. Beneath coarsely punc- 

 tured, punctures becoming smaller and dis ant upon the abdomen. Length 

 3.3 mm.; .125 inch. 



Texas, Belfrage, two specimens. The front coxae are moderately dis- 

 ;ta,nt, as in most of the glabrous species; the prosternum is slightly concave. 

 The club of the an'ennse is short oval, and the first joint constitutes more 

 : than one half the mass and is somewhat shining. In the best preserved
