Palp fairly slender, third segment tliree-fourths as long as second, fourth half 

 as long as third and shorter than fifth. 



Oviger long and slender, fourth segment two-thirds of length of fifth. 



Legs very long and slender, rather sparsely set with spinous sette, which become 

 more numerous distally and only here and there exceed in length the diameter of the 

 segment bearing them. Second coxa much longer than the other two together. 

 Femur more than one and a half times as lono- as the three coxae together, at least 

 sixteen times as long as its greatest diameter, with a row of about ten gland-tubercles

 less than twice as long as the femur. Tarsus longer by about one-third than the 

 propodus, the two together measuring about one-fourth of the second tibia. Main
