Prouotum very coarsely punr.tale and glabrous, or very nearly so. 

 the surface not deeply impressed along the apical margin, at 

 lea?( toward the middle: antennre much stouter, darker in color 

 than in any other species. New Mexico SPICTLT'M Csy. 



6 Prothor.ix hr^e, transverse, the lateral process long:, slender, finely 

 aciculate and abruptly formel, the surface unusually convex 

 longitudinally-, very coarsely and somewhat sparsely punctate 

 and glabrous, with short erect hairs toward the sides only ; an- 

 lennse slender and filiform. California (.Mt. Diablo). 



PILOSICORNIS Csy. 



The sexual characters are very feeble in this genus, and there 

 is a strong and persistent similarity of type throughout ; the 

 male characters evince themselves, however, in the slightly 

 longer antennae, with more elongate outer joints and in the 

 rather more dilated tarsi. In harri.fi there is a large transverse 

 discal area of the prouotum, which is very finely and densely 

 punctate, and of which there is no trace in the female or in 

 the male of sodalis. Pilosicornis is the most aberrant species 

 of the genus, and is wholly isolated from the other five in 

 many very radical structural characters.
