60 On new Scarabeeidge in the British Museum. 



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

 compressed, about three quarters tlie length of the tibiae, 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 sliort, with fringes of dense hair beneath, with four 

 acute tubercles on each side, projecting beyond the margin of 

 the elytra. 



This interesting genus may be })laced next to Bolhites ; 

 but the structure of the Iiind 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.
