Leptobunus 



Genus PROTOLOPHUS (Pro-tol'o-phus) 



This genus differs from all other members of the Phalangiidae 

 occurring in our fauna in having the last segment of the pedipalps 

 of the male shorter than the penultimate, and in that the patella 

 of the pedipalps of the female is provided with a long branch. 

 There is a median pair of large tubercles on the dorsal aspect o\ 

 each of the first five abdominal segments. Two species are found 

 in the Far West.
