 and. legs, and bright red abdomen. 



?. Length 14 nam. Legs 4123.

 which form tufts in front of the dorsal eves. The abdomen is 

 bright red on the back, with a narrow black band down the mid-

 the longitudinal forked band, described by Keyserling as albomaculatus. In other 

 cases the posterior transverse bars are united, giving a puzzling likeness to otiosus.
