The recent paper on Smicronyx by Dr. Dietz (Trans. Am. 

 Ent. Soc. xxi, p. 113), seems to be a painstaking and discrimi- 

 native piece of work, and it is for this reason more especially 

 that I regret to find myself still unable to accept his conclusions 

 regarding genera in the group Smicronychi, — not Desmorhines 

 or Desmori, be it mentioned, as Smicronyx is a much older. name, 

 long since adopted for the group in questioij. 



I fail, for example, to find the slightest difference in a generic 

 sense between the tibial structure of constridus and profusus, — 

 that is, between Desmoris and Smicronyx, — and the habital pecu-r 

 liarities of constridus are plainly reproduced in griscus and ob- 

 tedus, and, gradually less distinctly, in other species. The hind 

 tibiae are of the same general structure throughout, but in certain 

 species the spurs become relatively smaller, although preserving 

 the same form and inward, curvature; in these cases there is fre-
