are widely black, the middle only tomeutose; the preceding rings have a 
small round submarginal fuscous spot placed nearer to the base. 
Legs moderate sized, posterior the longest, intermediate the shortest; 
finely punctulate, pitchy, with a grayish pile ; the middle and a subapical 
spot of the thighs, a basal and an ante-apical spot of the tibiae (the latter 
subannular), the base of the two first joints of the tarsi thinly, the upper 
part of the 3rd, and the terminal with its claws, pitchy. Thighs clavate 
edentate, intermediate the shortest. Tibice subcylindric, a little curved at 
the base, somewhat dilated to the apex, which is truncate-subemarginate; 
anterior as long as the intermediate, but shorter-than their own thighs; 
posterior the longest, as long as their thighs, as well as the intermediate. 
Tarsi longer than the tibiae ; 1st joint the longest, more than a third of the 
total length, truncate; 2nd half the length of the 1st, emarginate; 3rd 
short, cordate, deeply bilobate; terminal arising from the base of the 3rd 
near the apex of the 2nd, nearly as long as the 1st, angularly dilated. 
Claws very divergent, incurved, unidentate beneath above the middle.
