the true affinity of tliis species in so much as he remarked in the 

 description of it tliat the venter of the female has a sickle-sliaped 

 callosity running backward inym the base. The rather strongly 

 curved anterior ti!)ia of the male is unarmed and the teeth of the 

 tore femora are not set in a single row; the outer series consists of 

 .1 few shorter teeth before apex, the inner series of several irregular 

 larger teeth, the first one about a third away from base between 

 which and apex are about five or six stout teeth, either one or two 

 near the middle usually licing tlic largest of the scries and those 

 before apex reduced in size.
