Coleopterological Notices. 373 



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 viatica 



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

 usually fulvo-ferruginons in color. 

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

 rugulose. 

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



eschscholtzi 

 Smaller and very slightly less convex ; prothorax distinctly shorter and 



more transverse Iiemoialis 



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 puiicticollis 



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 stlbpubesceiis 



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.) molilalia 



Small species (8.2-9.0 mm.) pallidicornis 



Elytral punctures distinct, larger than those of the pronotum. 



Pronotal punctures fine geilitiva 



Pronotal punctures very coarse parallela 



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

 pronotum very coarsely punctured ; pubescence throughout dens*, 

 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 setostis 



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

 have the eyes entire and simply emarginate anteriorly, those with 

 completely divided eyes being treated below as a distinct genus.
