Prothorax not conspicuously constricted at the sides. 



Elytra very densely squaniulo-pubescent, the vestiture often slightly thinner 

 along a subsutural and broader submarginal vitta. 

 Prothorax "longer than wide, distinctly carinate" ....inoriiatlis Lee. 

 Prothorax distinctly wider than long, not definitely carinate. 



canescens Lee. 

 Elytra sparsely pubescent, vittate with denser vestiture. 



Elytra marmorate with uneven patches of dense cinereous pubescence 

 which are more densely aggregated along the margin and in a broad 

 region between the first and fifth series of punctures. 



carinicollis Lee. 



Elytra with continuous marginal pale vitta and another between the 



second and fifth elytral series, the latter often divided into two vittaB,

speckled with spots of dense pubescence trivittatus Say

Elytra almost glabrous, sparsely pubescent toward base and on the third 



and fifth intervals behind the middle, also with a submarginal vitta ; each 



elytron subcarinate in the middle toward base l[)icai'inatUS n. sp. 



Elytra almost glabrous, with a narrow even vitta occupying the third inter- 

 val, and another, but slightly broader, along the lateral margin, both 



composed of dense pure white pubescence lecontei n. sp. 



Note. — The Mexican houcardi Chev. also belongs here and probably in the 

 neighborhood of lecontei. 



Sec. n. — Second joint of funicle much shorter than the first; body more slender, sub- 

 parallel; beak generally rather long, much thinner and not distinctly dilated at apex. 

 Elytra densely pubescent, with a narrow subsutural and broader submarginal 

 vitta partially or completely denuded. 

 Vittse extremely feebly defined, with the pubescence but slightly sparser ; 

 beak finely, very densely punctate and pubescent ; vestiture throughout 

 cinereous and extremely dense. Massachusetts. ..calandroides Kand. 

 Vittse well defined but strongly marmorate with denser patches. 



Pronotum strongly carinate, extremely coarsely, sparsely punctate. 



sparsiis Lee. 

 Pronotum not at all carinate, usually more strongly constricted near the 



apex, especially in the female frontalis Lee. 



puberulus Lee. 

 Vittje well defined and not or scarcely at all mottled, generally even. 



Prothorax without ocular lobes, the vibrissa very long ; pronotum dis-
