fold; anterior tibiz sharply tri-dentate outwardly and without an 
inner spur, intermediate and posterior one with an entire diagonal 
carina, and broadening towards the apex, apical spurs set between 
the tarsus and the lower angle, both not compressed, sharp at the 
tip; tarsi long, slender, joints bristly at the base, the two basal of 
nearly the same length, claws long, slender, very little curved, 
simple, not thickened or widened at the base. 
The two species included in this genus are pale-testaceous insects 
whose head, thorax, and pectus are as densely clothed with light 
flavescent hairs as some species of Cephalotrichia. 
So far as is known the genus has not been met with outside the 
South African limit.

Very light testaceous, and clothed, except on the elytra which are 
glabrous, with long, dense flavescent hairs; clypeus slightly arcuate 
in front with the outer angles somewhat rounded, nearly straight 
laterally, concave and made to appear still more so by the highly 
reflexed anterior part, very sparsely punctulate, each puncture bear-

which is very strongly arcuated towards the basal part in the centre,
