The basal stria of the elytra is very fine and is reflexed along the 

 scutellum, rather distant from the latter and not extending beyond it. 



O. rnfipes Lee. — Proc. Ac. Phil., 1856, p. 16. — Rather narrowly oval, 

 fully three-fourths longer than wide, rather distinctly attenuate behind from 

 basal fourth of the elytra, polished, piceous-black above, testaceous beneath, 

 the metasternum and abdomen clouded with piceous ; legs and antennae pale 

 flavo- testaceous. Head finely but rather strongly and distinctly punctate ; 

 antennae nearly as in vittatus. Prothorax more than twice as wide as long, with 

 a broad distinct median lobe at ])ase ; basal bead distinct except toward the 

 sides ; surface finely but rather distinctly, sparsely and somewhat unevenly 

 punctate, the punctures attenuate posteriorly. Scutellum ogival, one-half 

 wider than long. Elytra three times as long as the prothorax ; sutural bead 

 very fine, becoming obsolete near the base ; discal striae fine but distinct, both 

 becoming obsolete at basal third, the first coincident with the suture at the 

 extreme apex, the second approaching but not joining the first at apical fourth 

 or fifth ; having also series of exceedingly minute simple punctures which are 

 scarcely more distinct at the sides, the series accompanied by fine, feebly im- 

 pressed lines which almost attain the basal stria ; surface with very feeble, 

 densely crowded, longitudinally acicnlate reticulations, which are extremely 

 minute, more distinct at the sides and especially at the apex, where they 

 become more rounded and less aciculate. Abdomen sparsely pubescent, alutace- 

 ous. ie^s moderate ; posterior tarsi slender, three-fourths as long as the tibiae, 

 with the first joint about one-third as long as the second. Length 2.0 mm. 



Oregon. Cab. LeConte. 



The metasternum is polished, although finely reticulate, very 

 sparsely, finely punctate and pubescent; the process is rather wide, 

 projecting beyond the coxae, with the apex broadly rounded, almost 

 subtruncate in the middle, the mesosternum not distinct at the sides. 



This species differs from the preceding in its broader, more 

 obtusely rounded metasternal process, which is here about as w^ide 

 as the anterior femur ; in neglecfus it is not much more than two- 

 thirds as wide. 



O. TV^icktiami n. sp. — Elongate-oval, nearly twice as long as wide, 

 more or less attenuate from anterior third, black above, piceous beneath ; 

 trophi, antennae, tibije and tarsi paler, rufo-testaceous ; shining. Head very 

 finely, sparsely punctate ; antennae moderate in length, rather slender, third 

 joint as long as the next two together, club of nearly normal form but slightly 

 less strongly compressed, slightly more parallel and less robust. Prothorax 

 but slightly more than twice as wide as long ; sides less arcuate than usual ; 

 basal lobe broadly arcuate ; basal bead very feeble ; surface polished, not at 

 all reticulate, extremely minutely, feebly and sparsely punctate. Scutellum 

 moderate, ogival, nearly twice as wide as long. Elytra three times as long as 

 the prothorax ; sutural bead very fine, not becoming entirely obsolete at the
