Thorax truly cylindrical, longer than wide: general surface color less the pu- 

 bescence, brown.

 cinereo-pubescent with small rounded denuded spots more abundant at the 



sides and a larger denuded spot behind the middle Wildii. 



Thorax not wrinkled, punctuation distinct : pubescence of elytra rather sparse,

I^. calirornica n. sp. — Brown, feebly shining, moderately elongate, cylin- 

 <irieal, slightly depressed. Thorax wider than long, moderately convex, sparsely 

 coarsely punctate, sparsely cinereo-pubescent. Elytra wider at base than the tho- 

 rax, punctuation coarse and moderately close near the base, much more distant 

 near the apex, surface sparsely cinereo-pubescent forming an indistinct design of 

 longitudinal interrupted and somewhat angulated lines. Body beneath coarsely 

 sparsely punctate, moderately densely cinereo-pubescent. Length .36 inoh ; 9 mm. 



One male specimen, the antennae one-third longer than the body. It 

 resembles y«scafa, but differs in the form and punctuation of the thorax, 

 that of fuscata being square, densely and coarsely punctured. 



One male, San Diego, California.

 pubescent, elytra with denuded spots, tuberculiform at base, flat posteriorly ; 



.75 inch; 19 mm pustulata Lee.

 a broad ante-median band paler, and numerous spots of brownish yellow 



arranged in four irregular rows; .68 inch; 17 mm putator Thoms.
