not carinate laterally above the eyes, and having a basal, arcuate, 
only slightly raised keel; antennz 10-jointed, joints sixth and seventh 
short, compressed, eighth, ninth, and tenth forming a club not quite 
as long as the pedicel, laminate and somewhat dilated at the tip, 
apical joint somewhat shorter than the one preceding; prothorax 
nearly twice as broad as long, slightly convex, and with the posterior 
angles moderately rounded ; scutellum sub-ogival; elytra parallel, 
moderately convex near the base, barely covering the base of the 
propygidium ; pygidium sub-vertical, slightly convex; intermediate 
and posterior tibiae without an outer oblique ridge; anterior ones 
with an inner spur, and tri-dentate outwardly, hind spurs somewhat 
slender and moderately long; hind tarsi somewhat bristly under- 
neath ; claws long and having underneath a very small, juxta-basal 
vertical tooth. 
The only species included in this genus is a very singular insect 
which, unlike the other South African Pachypodini, has strongly 
costate elytra, with the intervals filled with appressed, distinctly 
squamose hairs. The female is unknown. I have seen the type 
of the genus which is in the Schénherr Collection in the Stockholm 
Museum.

Schonh. Syn. Insect., i., 3; Append., p. 87. 
Male: Piceous, club of antennex slightly reddish-brown; head, 
prothorax, pectus, and abdomen clothed with a somewhat light 
fulvous pubescence longer on the sides and base of the thorax, 
and also on the pectus; intervals of elytra filled with somewhat 
long, scale-like greyish fulvous scales; clypeus separated from the 
frontal part by an ill-defined, transverse suture obliterated in the 
centre, and like the frontal part it is covered with deep, round punc- 
tures from each of which springs a short hair, longer, however, on the 
frontal part the basal ridge of which is not very sharp ; prothorax 
plainly ampliated laterally in the middle, deeply punctured, with the 
punctures larger and less closely set in the anterior part, and having 
a longitudinal impression in the median part only of the disk ; 
scutellum moderately closely punctured, except in the apical part; 
elytra parallel, not much convex, but somewhat abruptly convex 
behind, strongly quadri-costate on each side, and with the suture 
also highly raised, the punctures are nearly smooth and shining, 
and the intervals, as well as the outer margin, are covered 
with scale-like appressed hairs springing from somewhat shallow 
punctures; propygidium aciculate; pygidium punctulate, clothed, 
like the abdomen, with appressed hairs, and having a fringe of
