the sternal parapleurae. Head coarsely, deeply, very densely punctate, flat 

 and longitudinally rugose between the eyes, sparsely clothed with short 

 whitish hairs ; eyes large, rather convex, separated by four-fifths of their own 

 width ; beak thick, scarcely arcuate, not quite as long as the prothorax, 

 gradually, distinctly dilated toward apex, with two approximate eroded and 

 unevenly punctate grooves in basal half, separated by a smooth impunctate 

 line, laterally very coarsely, deeply, densely punctate and rugose but not sul- 

 cate, above toward apex strongly punctate and with two widely distant longi- 

 tudinal impressions ; antennae inserted at apical third, the second funicular 

 joint obconical, three-fourths as long as the first, club elongate-oval, densely 

 pubescent, darker in color. Prothorax very slightly longer than wide, the apex 

 broadly arcuate, a little wider than the base ; sides subparallel and nearly 

 straight in apical two-thirds, then gradually rounded, convergent and sinuate 

 to the base ; disk coarsely, deeply, unevenly and closely punctate, the punc- 

 tures becoming finer near the apex, sparse on the flanks toward base and with 

 a narrow subentire tumid impunctate line along the middle. Scutellum 

 small, densely covered with yellowish-white tomentum. Elytra at base two- 

 thirds wider than the base of the prothorax, two and one-half times as long, 

 three-fourths longer than wide, only slightly wider behind the middle than at 

 base ; humeri obtusely angulate, scarcely rounded, subprominent ; disk with- 

 out series but with moderately fine, deeply impressed punctures unevenly 

 distributed in longitudinal vittse, separated by subimpunctate narrower lines, 

 which have exceedingly remote larger punctures bearing the stiff erect setae. 

 Legs moderate in length, sparsely pubescent, the femora distinctly, acutely 

 toothed beneath. Length 5.5 mm. ; width 2.2 mm. 



New Mexico (Las Vegas). Mr. Meeske. 



The uneven, sculpture and sparse recumbent vestiture distinguish 

 this species from any other within oar fauna; it may perhaps be 

 allied to the Mexican jlavipennis Chev. 



6 O. egregillS n. sp. — Oblong-ovoidal, strongly convex, rather robust, 

 black and polished throughout, the upper surface clothed sparsely but con- 

 spicuously with short robust recurved white setae, unevenly scattered on all 

 the interval of the elytra and mingled with longer finer erect and more widely 

 dispersed piceous setae ; legs and under surface rather sparsely but distinctly 

 clothed with short and more recumbent white hairs, dense and tufted on the 

 sternal side-pieces and mesosternum between the coxae, also with sparser 

 tufted hairs on the prosternum and toward the anterior margin of the meta- 

 sternum. Head coarsely but not very densely or deeply punctate ; eyes large 

 although not very prominent, separated by one-third of their own width ; beak 

 thick, just noticeably wider at apex, feebly bent, three-fourths as long as the 

 prothorax in the male, smooth and impunctate broadly along the middle, with 

 a feeble impressed line between the antennae, coarsely, closely punctate and 

 longitudinally sulcate laterally, hispid with erect setae ; antennae inserted at 

 apical third, long, slender, the first funicular joint a little longer than the next 

 two, club rather small, elongate, pointed, asymmetrically fusiform. Prothorax
