granulose and the elytra very minutely, rather sparsely punc- 

 tulate throughout and not more closely or granularly so toward 

 the scutellum. The abdomen is always more finely and closely 

 punctulate. The remarkably small corneous plates of the 

 prosternum have been previously referred to in sufficient de- 

 tail, and this and other characters have been fully stated in 

 the table of genera. Our seven species are readily separable 

 into two distinct groups as follows : — 



Elytra larger and more transverse, very much wider and always distinctly 

 longer than the prothorax, the humeri widely exposed at base and 

 moderately oblique S 



Elytra much smaller and narrower, never longer and much less distinctly, 

 though very obviously, wider than the prothorax, the humeri narrowly 

 exposed at base and more oblique; sides of the elytra rather more 

 divergent from base to apex t 



2 — Prothorax widest and rather broadly rounded at the sides at or near 



apical two- fifths 8 



Prothorax distinctly elongate, widest and strongly rounded at the sides much 

 nearer the apex 4 



3 — Form moderately slender, convex, polished, ruf o-testaceous in color, the 



elytra rather more brownish, the abdomen with a very faint darker 

 cloud, especially posteriorly; legs and antennae pale; pubescence 

 rather abundant throughout but fine, short and pale, somewhat distinct; 

 head slightly wider than long, broadly rounded at base, the sides be- 

 coming parallel for a short distance behind the eyes, the surface very 

 minutely, sparsely and scarcely visibly punctulate, not impressed except 

 very obsoletely on the median line toward base ; antennae extending to 

 basal third of the elytra, strongly incrassate distally, the subapical 

 joints evidently transverse, the first three equal in length, the first 

 slightly thicker; prothorax equal in width to the head, very slightly nar- 

 rower in the male, convex, very finely and evenly punctulate, the punc- 

 tules more asperate and closer than those of the head; sides distinctly 

 convergent and straight posteriorly, the base broadly arcuato>truDcate, 

 fully four-fifths as wide as the disk; elytra two-thirds to three-fourths 

 wider and two-fifths lenger than the prothorax, not evidently impressed 

 on the suture behind the scutellum, finely, not very sparsely and obvi- 

 ously punctulate, very evenly so throughout, the sides slightly diverg- 

 ing from base to apex; abdomen parallel with the sides distinctly, 

 almost evenly arcuate, not quite as wide as the elytra, minutely, closely 

 punctulate, less minutely, more sparsely and asperulately toward base, 

 the first Impression with numerous coarser punctures not very close- 

 set, the other two with but few such punctures. Length a.i mm. ; 

 width 0.58 mm. California (Sta. Clara and Monterey Cos.) . [= Falagria

Form nearly similar but more slender, similarly colored, the head relatively 

 larger, excessively minutely, sparsely punctulate, the antennae some-
