traces of an inner lobe; last joint of maxillary palps fusiform, twice 
as long as the third, and not impressed laterally, maxille laminate 
and bifid at the tip; labrum narrow, transverse, not sub-cordate, not 
incised; clypeus separated from the head by a very faint suture, 
either diagonally narrowed laterally and truncate in front (Apogonia), 
or strongly aculeate and incised in the centre, or even bi-lobate in 
the male (Catagonia, Ceratogonia), head large, eyes large, divided in 
the anterior part by the canthus of the genz which are, however, 
fused with the clypeus; antenne 10-jointed, the first and second 
joints are as long as the rest of the pedicel, much thicker than the 
other joints which are small and moniliform, the three-jointed club is 
elongate in the male, ovate in the female; prothorax twice as broad 
as long, anterior angles very sharp, posterior ones angular, anterior 
margin not fringed with hairs; scutellum ogival; elytra broader than 
the prothorax and with the humeral angles sharp, moderately convex, 
costulate, not callose behind, covering the propygidium or the greatest 
part of it; pygidium small, cordate, declivous ; abdomen convex, the 
segments fused, pectus not hairy; anterior tibiz bi- or tri-dentate 
outwardly, and with a very distinct inner spur (Catagonia, Apogonia), 
or without (Ceratogonia), posterior ones without a distinct oblique 
ridge, tarsi long, hairy underneath, especially in the male, in which 
sex the two basal joints of the anterior tarsi are somewhat dilated at 
the apex, especially the second (Apogonia), or the three basal joints, 
the second in particular, very broadly dilated in all the tarsi (Cata- 
gonia, Ceratogonia), claws somewhat robust, deeply cleft at the apex, 
the lower tooth as arcuate as the upper, nearly as long, and slightly 
broader. 
The genus 1s represented in India, Ceylon, Borneo, Java, Sumatra, 
&e. It occurs also in East and West Africa, and five South African 
species are now known.
