1'jOO.J Catalotjuc of the Colcopicra of South Africa. 65 



each side and fringed on the top with dense, long, cihate hairs; first 

 joint of labial palpi thick, one-third longer than broad, second half 

 the length of the first, massive, a little incurved, truncate at tip, 

 last joint narrow, sub-cylindrical, sul)ulate, also truncate at tip ; 

 maxilla; concave inwardly, upper lobe lateral, moderately broad, 

 inner one short, maxillary palpi moderately long, their apical joint 

 fusiform, grooved underneath ; antennae nine-jointed, basal joint 

 longer than the five following, second short, the other six ob-conical, 

 club tri-foiiate ; head with a semicircular clypeus bi- or quadri- 

 dentate in front ; eyes divided into two, the upper part smaller than 

 the lower; prothorax convex, sinuate in the anterior pai't and with 

 the outer angles sliarp, sub-diagonally ampliated from there to past 

 the middle where the sides are nearly straight as far as the base, or 

 very slightly rounded ; all the outer margins are more or less 

 sharply carinate, the lateral one being often bi-carinate for the 

 whole length or part of it, but always slightly recurved towards 

 the base and produced there in a distinct angular point ; the disk 

 is very convex, and there is on each side a supra-lateral, con- 

 spicuous, round impression, and sometimes a smaller one on each 

 side of the median part of base ; scutellum wanting ; elytra sinuate 

 on each side along the base, always sharply carinate, the carina 

 being broadly emarginate, and leaving the angle of the three ventral 

 segments uncovered ; they are always a little attenuate towards the 

 apex, rather plane than convex, and a little callose above the apical 

 part ; pygidium nearly vertical ; metasternum produced in front in 

 a more or less sharp, triangular, aculeate process, median part very 

 broad between the coxae the cotyloid cavities of which are not very 

 diagonal, generally finely grooved in the centre, and more or less 

 impressed at base ; legs moderately strong, anterior tibite tri-dentate 

 outwardly, and provided with tarsi armed with a long claw, always 

 serrate outwardly and also inwardly, posterior and intermediate tibiae 

 curved inwardly, provided with a long, incurved spur, more or less 

 distinctly bi-dentate' at apex and always closely serrate outwardly ; 

 in the male the apical part of the anterior tibiae is often mucronate 

 inwardly, and the spur is broad and obliquely truncate at 

 apex. 



The specific differences in the genital armature are not sufficiently 

 distinct to be of much use. 



The species of this genus have the same habits as those of 

 ScarabcBUS, and the larvae are similar. The genus is represented 

 in Europe, India, Asia, and Ceylon, but the species are very 

 numerous in Africa, and they are so closely allied that their 

 identification is very difficult.
