fold; anterior tibiae 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 Gephalotrichia. 



So far as is known the genus has not been met with outside the 

 South African limit. 



Key to the Species. 



A 2 . Body and elytra light testaceous, hairs flavescent. 



B 2 . Clypeal suture semicircularly curved in the centre towards 

 the frontal part. 



Clypeus straight laterally, with the outer angles slightly 

 rounded helvola. 



Clypeus narrowed laterally and with the outer angles 



broadly rounded delicatula. 



B 1 . Clypeal suture transverse. 



Clypeus deeply punctured, anterior margin hairless, frontal 



part normally pubescent blandula. 



Clypeus impunctate, anterior margin and frontal part with 



a row of stiff, closely set bristles echinaticeps . 



A 1 . Body black, elytra fuscous, hairs greyish.

 Entomogr., 1840, p. 42. 



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- 

 ing an erect hair, divided from the frontal part by a sutural line 

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

 frontal part very closely punctured and densely hairy, the hairs
