distinguished by a character similar to that I notice in our Mexican specimens. It 
would thus seem probable that the New-World species is distinct from that of 
Europe.

Hab. Nortu America ! ?,—Mexico !. 
The distinction of this species from the North-American var.? of B. urtice appears 
from Horn’s remarks ? to be very doubtful.

Priops, Reitter, Verh. Ver. Briinn, xii. p. 167. 
Six species of this genus are described from South America, besides the one from our 
region on which Reitter founded the genus Priops, and there is a species described by 
Erichson from Madagascar. Reitter assigned Priops to Brachypterine, but without 
dissecting the mouth, and without noticing that his species is extremely close to 
Mystrops debilis, Er.; and I must therefore place his genus at present as a synonym 
of Mystrops. At the same time it is only proper to remark that Mystrops is composed 
of species of heterogeneous appearance; and it is quite probable that it may require 
to be divided, and even that some of its components may have to be placed in the 
Brachypterine, in which case Reitter’s name will be restored for his species and
