Sides of the head less prominent than the posterior canthus of the eye ; 

 sides of the prothorax more strongly convergent from base to apex ; 



body more longitudinally convex Tiatica 



Vestiture consisting of long and distinctly visible hairs or setae, which are 

 usually fulvo-ferruginous in color. 

 Elytral punctures very coarse and deep, the surface more or less strongly 

 rugnlose. 

 Larger species ; head relatively slightly larger and more finely punctate. 



eschscholtzi 

 Smaller and very slightly less convex ; prothorax distinctly shorter and 



more transverse nemoralis 



Elytral punctures fine or moderate in size ; surface generally more or less 

 obsoletely rugulose. 

 Pronotal punctures very dense ; elytral punctures extremely fine and un- 

 evenly distributed, being aggregated in undefined longitudinal masses ; 



size very small ; form slender piincticollis 



Pronotal punctures but moderately dense toward the sides ; elytral punc- 

 tuation even or very nearly so. 

 Elytral pubescence toward apex moderately dense, fine and recumbent. 

 Head moderate in size, never much less than one-half as wide as the 

 base of the prothorax. 

 Form broadly evenly oval, strongly convex, and not more than 



twice as long as wide ; very dull allltacea 



Form more or less oblong-elongate, with the sides nearly straight ; 

 body more depressed. 

 Prosternum very coarsely, deeply punctate ; pubescence of the 



upper surface long and conspicuous silbpubescens 



Prosternum more finely and sparsely punctate ; pubescence of 

 the upper surface much less conspicuous. 

 Elytral punctures very fine, distinctly smaller than those toward 

 the sides of the pronotum. 



Larger species (10,8-13.0 mm.) moil tana 



Small species (8.2-9.0 mm.) palliilicoi'llis 



Elytral punctures distinct, larger than those of the pronotum. 



Pronotal punctures fine genitiTa 



Pronotal punctures very coarse parallela 



Head very small ; prothorax strongly narrowed from base to apex, the 

 pronotum very coarsely punctured ; pubescence throughout dense, 

 long, persistent and very conspicuous ; form elliptical, convex ; 



size small parviceps 



Elytral pubescence toward apex extremely dense, short, erect, coarse 

 and hispid ; body oval, very convex setosilS 



The genus, as here considered, is confined to those species which 

 have the eyes entire and simply emarginate anteriorl}^ those with 

 completely divided eyes being treated below as a distinct genus.
