first joint less than one-third as long as the second, apparently suhanchyloscd, 

 second as long as the fifth exclusive of the basal node, which is unusually 

 robust and well marked. Length 2.G mm.

The punctures of the elytral series are minute points, apparently 

 absolutely non-setigerous. The metasternal process extends beyond 

 the coxae, and rests upon the indexed prosternal process ; it is 

 strongly rounded at apex, very finely beaded throughout, and 

 around the edges of the middle acetabula ; its surface is polished, 

 with a few excessively minute feeble and widely scattered setigerous 

 punctures ; the sides are slightly divergent from apex to base, at 

 which latter point it is about three times as wide as the prosternal 

 .process, and as wide as the length of the last antennal joint. There 

 is sometimes a very short isolated third elytral stria. 



The species de.scribed by LeConte as striatulus, 1 believe to be 

 the same as this, and the above description is taken from the origi- 

 nal type of Htriatulus. 



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

 and very evenly elliptical, strongly convex, highly polished, castaneous above, 

 pale rufo-testaceous beneath ; legs, tropin and antennje concolorous. Head 

 rather coarsely but not densely punctate ; eyes moderate ; antennfe moderate, 

 third joint fully as long as the next two together, club rather robust, nearly 

 as in paUi'pes. Prothorax twice as wide at base as at apex, distinctly lobed in 

 the middle at base, the edge sightly sinuate opposite the scutellum ; basal 

 bead distinct, becoming obsolete at one-fourth the width from the sides ; sur- 

 face very sparsely, unevenly, feebly punctate, the punctures subelongate. 

 Scutellum moderate, wider than long, rounded at the sides. Elytra three 

 times as long as the prothorax, strongly, evenly rounded at apex, polished, 

 without reticulation except very near the apex, not perceptibly so at the 

 sides ; sutural bead very fine, continuous to within a very short distance of 

 the scutellum ; first discal stria joining the suture at the apex, vanishing at 

 less than one-third the length from the base ; second distinct, obsolete at one- 

 third the length from the base and one-fifth or one-sixth the length from the 

 apex, approaching but not uniting with the first ; basal stria continuous along 

 the scutellum ; disk with series of very fine feeble evidently elongate punc- 

 tures, distinctly stronger at the sides, and accompanied by distinctly impressed 

 lines which are continuous to the base. yl6(i?o;«eM moderately pubescent. Legs 

 rather robust ; posterior tibial spurs distinct, the corresponding tarsi three- 

 fourths as long as the tibiae, with the first joint one-half as long as the second. 

 Length 1.9-2.4 mm.

The metasternum is polished, with very sparse fine pubescence, 

 the punctures excessively minute and entirely filled by the hairs,
