2D6 CUECULIOJVID.^. [LeConte. 



slrong'y marked punctures. Prosternum very wide between the coxse, 

 coarsely punctured, with two slight longitudinal impressions in front. 

 Length 4 mm.; .15 inch. 



Texas, Belfrage, one specimen. 



4. O. distans (Lee), Pr. Ac. Nat. So. Phil. 1868, 363, {Bari(Uu!<). 

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



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

 tlie prothorax, not stout, regularly and s'rongly curved, frontal constriction 

 feeble. Prothorax suddenly narrowed, rounded on the 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 

 deep strine, interspaces flat, ratlier wide, wi;h rows of shallow dis ant punc- 

 tures, which are more evident than usual. Pros ernura very wide between 

 the coxae, coarsely and spars jly punctured, broadly concave in front, with 

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



5. O. seriata (Lee), Pac. R. U. Expl. and Surv. Ins. 58; Pr. Ac. Nat. 

 Sc. Phil. 1868, 363, {Baridui'<). 



■ San Francisco, Cal. ; one specimen. A small, shining black species of 

 narrow form, resembling in this resp 'ct the ne■K^ as well as Baris xixtri^a, 

 and Pitendob'iriH angusta. From the last two it is easily distinguis'ied by 

 the generic characters; from 0. mdcra it is readily kn;nvn by the more dis- 

 tant front coxae. The pros' ernum is as wide as in the two preceding spe- 

 cies, flat and coarsely punctured, without impressions. The third joint of 

 the tarsi is less broadly dilated. 



II .'ad dull, feebly i)unc'.ulate; beak as long as the prothorax, not stout, 

 rugosely punc'ured, regularly curved, frontal constriction faint. Pro', bo- 

 rax scarcely longer than wide, sides rounded in front, and scarc;'ly con- 

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

 with rather narrow strise, interspaces flat, each with a row of small distant 

 punctures. Length 2.5 mm.; .10 inch. 



6. O. cribrata, n. sp. 



EU)ngate, brownish black, shining, sparsely clothed with rather coarse 

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

 thorax, stout, curved, punctured, stronglj^ 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, stri;B deep, interspaces narrow, each with a row of rather distant 

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

 tured, punctures becoming smaller and distant upon the abdomen. Length 

 3.3 mni.; .135 inch. 



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

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

 The club of the antennae is short oval, and the first joint constitutes more 

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