COLEOPTERA OF SOUTHERN CALIFORNIA. 261 



augulate; disk with moderate basal depression, obtusely carinate ante- 

 riorly; punctuation rather strong, sparse, and unevenly distributed. 

 Elytra a little more than twice as long as wide, about one-third wider than 

 the prothorax; hunieri obliquely rounded; apices divergent but not pro- 

 duced; the series of rather fine punctures unimpressed except the sutural; 

 third and sixth intervals moderately elevated at base. Beneath speckled 

 with subdenuded punctures. Legs moderate, lobes of third joint of hind 

 tarsi completely spongy pubescent beneath. 

 Length, 13 mm. 



A single specimen was taken on Astragalus crotalarce, 

 at Redondo, in April. 



According to Casey's table the species should come 

 between G. inornatus and C. canescens. 



81. Cleonus erysimi, sp. nov. 



Elongate, subparallel, densely clothed with rather fine whitish recum- 

 bent squamiform hairs which nearly conceal the sculpture; the disk of the 

 pronotum, except two anteriorly convergent dorsal vittae, and the sutural 

 and eighth elytral intervals, glabrous. Beak nearly three-fourths as long 

 as the prothorax, scarcely broader at tip, densely, finely punctate with 

 coarser punctures intermixed, more or less distinctly carinate, frontal 

 impressions well marked. Prothorax slightly longer than wide, sides 

 straight and nearly parallel almost to apex, where they are feebly narrowed 

 and slightly constricted; basal lobe moderately prominent, rounded or 

 truncate at apex; basal excavation not deep; disk obtusely prominent 

 anteriorly along the median line, but not distinctly carinate; coarser 

 punctures sparse at middle, more numerous at sides. Elytra but little 

 wider than the prothorax, apices divergent but not produced, punctures of 

 striae not coarse, the striae not impressed; third and sixth intervals feebly 

 elevated at base. Lower surface and legs about as usual. 



Length, 7.5-11.5 mm. 



Many specimens have been seen, occurring only on 

 the flowers of Erysimum asperum. on the sand-hills over- 

 looking the ocean at Redondo; March and April. 



The sutural interval is pubescent at base and through- 

 out its outer fourth, and the eighth is thinly clothed 

 posteriorly. The ocular lobes are nearly wanting. The 

 third joint of hind tarsi is completely spongy pubescent
