60 On new Scarabasidas in the British Museum. 



one reaching to the fourth joint of the tarsi ; tarsi broad, 

 compressed, about three quarters the length of the tibiee, the 

 basal joint triangular, a little broader than long, claws 

 absent. Posterior legs with the femora subparallel ; the tibiae 

 moderately long, gradually but not very much widened 

 towards the apex, the outer edge with an irregular series of 

 small tubercles ; the tarsi about two thirds the length of the 

 tibia, fringed on both sides with long hair, flat, broad, the 

 basal joint scarcely longer than broad, the third and fourth a 

 trifle broader than long, irregular-ovate, claws absent. Abdo- 

 men very short, with fringes of dense hair beneath, witli four 

 acute tubercles on each side, projecting beyond the margin of 

 the elytra. 



This interesting genus may be placed next to Bolbt'tes ; 

 but the structure of the hind legs and especially the tarsi is 

 quite different.

The posterior femora have the rusty fringe of hair on the 

 anterior margin only ; the posterior tibiae, besides the thin 

 fringe on the outer and inner edge, have a fringe of dense 

 hair on the upper surface, commencing at the inner angle of 

 the base and extending to the middle of the apex.
