I have examined the male of the first form of this species pre- 
served in the Philadelphia Academy, from Mirador, Mexico 
(already mentioned by Faxon). The copulatory organ belongs 
to the type of the subgenus Procaméarus and is allied to that of 
C. williamson? and pilosimanus. It differs in the very strongly 
developed shoulder, and the position of the horny, procurved 
spine, which is almost terminal on the inner part. The tips of 
inner and outer part resemble those of C. wzd/zamsont. 
An additional locality for this species is represented in the 
collections of the Philadelphia Academy: 
Texolo, State of Vera Cruz, Mexico. —S. N. Rhoads coll. 
1899. —3 o' (II), 2 . (Texolo is near Xico, on the branch 
road from Jalapa, distant about 15 miles from Jalapa.) 
In the males of the second form of this set, the shoulder of 
the sexual organs is not quite so sharp, and the inner part is 
more pointed.
