rather more than hz as long as the body, not very stout, moderately attenu- 

 ated, the basal joint thick and obconic and the third and fourth joints broadly 

 constricted near the middle as usual. Prothorax y wider than long, rounded 

 laterally and widest at apical third, the sides thence rather strongly convergent 

 and feebly but evenly arcuate to the basal angles, which are slightly obtuse 

 but uot very blunt ; lateral margin attaining the basal bead, the latter only 

 visible toward the sides ; disk broadly and feebly convex, finely and feebly 

 vermiculato-rugose, the median line fine. Elytra short, scarcely }4 longer 

 than wide, ^.5 wider than the prothorax and 2% times as long, widest at the 

 middle, the sides evenly arcuate ; lateral margin distinctly reflexed, more 

 broadly and conspicuously toward base; disk moderately convex, rather coarsely, 

 closely and subconfluently punctate, the foveolse small. Length 14 mm. ; 

 width 5.5 mm. 



California. 



The single female before me represents a species rather closely 

 allied to the last but differing in its shorter, more densely punc- 

 tured elytra and more elongate prothorax, the latter being more 

 broadly rounded at the sides anteriorly. From californicus it 

 differs in its shorter and broader form, in sculpture and in having 

 the lateral margins of the elytra conspicuously reflexed toward 

 base ; it is from an unrecorded part of the State. 



O. sculptilis. — Moderately slender, strongly couA-ex, shining and deep 

 black. Head moderate in size, deeply and closely vermiculate, the front 

 rugose throughout and not puuctate; impressions moderate; labrum almost 

 truncate, the median lobe very broadly and evenly arcuate, the lateral sinua- 

 tions feebler than usual, the six setigerous punctures strong; antennae moderate, 

 fully ^2 as long as the body, distinctly attenuate. Prothorax scarcely more 

 than }^ wider than long, the sides moderately convergent from apex to base 

 and broadly and rather evenly arcuate throughout, widest toward apex as 

 usual; side margins attaining the basal bead, which is traceable entirely across 

 the surface, as is also a line anterior to the base and another, broadly angulate, 

 behind the apex; basal angles obtuse but not rounded; surface strongly con- 

 vex, deeply and closely vermiculato-rugose throughout; median line fine but 

 distinct between the transverse lines. Elytra evenly suboblong-oval, widest 

 at the middle, fully ^2 longer than wide, % wider than the prothorax and 2% 

 times as long, the sides feebly arcuate but more strongly near base and apex; 

 margin finely reflexed; punctures strong and not confluent; foveolse small. 

 Length 16.0 mm.; width 5.6 mm. 



California, 



The only representative was taken by the author in the coast 

 regions north of San Francisco ; it is a male and represents a 

 species allied to, and considerably resembling californicus, espe- 

 cially in sculpture, but differing in the rounded sides of the pro- 

 thorax and feebly lobed labrum.
