1904.] Catalogue of the Coleoptera of South Africa. 51 



Length 6-8 mm. ; width 4-5 J 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 ; antennas 

 flavous ; as elongato-ovate as T. ferrugineus, but easily distinguished 

 by the opaque indument on the upper side ; the sculpture and the 

 shape of the clypeus are as in T. 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 6-6^ mm. ; width 3f-4 mm. 



Hab. Transvaal (Lydenburg). 



Trochalus urbanus, n. spec. 



Elongato-ovate, testaceous-red, shining ; antennae 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 tibiae bi-dentate. 



This species is easily distinguished by the clypeus, which is very 

 little constricted laterally. 



Length 6J mm. ; width 4 mm. 



Hab. Southern Ehodesia (Salisbury). 



The valves of the genital armature are symmetrical, acuminate, 

 bent at the base, and sub-horizontal thence. 



Trochalus sebakuanus, n. spec. 



Shape, colour, and sculpture of the preceding species, from which 

 it differs by the shape of the clypeus, which is constricted laterally,
