1904. | Catalogue of the Coleoptera of South Africa. 51 
Length 6-8 mm.; width 4-54 mm. 
Hab. Cape Colony (? Cape Town, Mossel Bay, Port St. John) ; 
Natal (Durban) ; Transvaal (Zoutpansberg, Lydenburg). 
The variation in the size and convexity of the body is such that 
had it not been for the shape of the genital armature I would have 
considered these variations as good specific characters; the colour is 
also very variable. 
TROCHALUS LEPIDUS, n. spec. 
Bronze-green, with the elytra brownish-red or partly rufescent, 
opaque on the upper side, and occasionally sub-iridescent; antenne 
flavous ; as elongato-ovate as 7’. ferrugineus, but easily distinguished 
by the opaque indument on the upper side; the sculpture and the 
shape of the clypeus are as in 7’. ferrugineus ; in the male the right 
valve of the genital armature is a little longer than in the last-named 
species, but the shape is almost the same in both. 
Length 6-64 mm.; width 33-4 mm. 
Hab. Transvaal (Lydenburg). 
TROCHALUS URBANUS, n. spec. 
Hlongato-ovate, testaceous-red, shining ; antenne with the pedicel 
testaceous and the club flavous; clypeus truncate in front and with- 
out any angular part in the centre of the anterior margin, the outer 
angles are plain but not reflexed, the anterior part is only very 
slightly constricted laterally, and the lateral margin is not strongly 
sinuate ; the punctures on the clypeal part are deeper than on the 
frontal; the prothorax and the elytra are deeply and somewhat 
closely punctate, the elytra are plainly striate on the sides as well as 
on the dorsal part ; the clypeus has no traces whatever of a longi- 
tudinal keel; anterior tibiz bi-dentate. 
This species is easily distinguished by the clypeus, which is very 
little constricted laterally. 
Length 64 mm.; width 4 mm. 
Hab. Southern Rhodesia (Salisbury). 
The valves of the genital armature are symmetrical, acuminate, 
bent at the base, and sub-horizontal thence. 
TROCHALUS SEBAKUANUS, 0. spec. 
Shape, colour, and sculpture of the preceding species, from which 
it differs by the shape of the elypeus, which is constricted laterally,
