ridges or rows of bristles outwai'dly ; tarsi a little compressed, 

 moderately long, and somewhat robust, claws diverging, equal in 

 length, and having underneath in the anterior and intermediate tarsi 

 a tooth not as long, but nearly as much curved as the claw itself, but 

 simple, slender, and not diverging, and of equal length in the 

 posterior tarsi ; hind tibiae gradually dilated from base to apex, 

 strongly ciliate there, almost lobate inwai'dly at the apex, and having 

 a dense, inner fringe of hairs in the male, and provided with two 

 long apical inner spurs in both sexes. 



This aberrant genus of the RiiteUnce is the only one in which the 

 claws of the anterior and intermediate tarsi are diverging and have 

 underneath a strong tooth, much in the manner of the MclolonthincB. 



The genus includes three species, two of which are from the 

 Sudan ; one of these is also met with in South Africa.
