114 ntOCEEDINGS OF THE NATIONAL MUSEUM. 



I have had before me there has been no noticeable variation, except 

 that of size, and a little in tiic ground color. Tlie head is small, 

 closely applicil to the thorax; tbe front convex, but not bulging; the 

 palpi well developed, free from the front and extending at least to its 

 middle. The anterior legs of the mah^ are well develo])ed; the femur 

 of moderate size, quite distinctly dilated at the middle, and the tibia 

 moderately broad, with the epiphysis inserted close to the base. The 

 harpes of tlie male are short and (juite broad, a little narrowed at the 

 tip and rounded. The clasper is distinct, twisted, beak-like, with a 

 little tuft of diverging hair. This species can not be easily mixed with 

 any other within its range, and its nearest ally is the Western species 

 just described as rcvidlata.
