being plainly sinuate in the middle of the anterior part, the punctures 

 on the prothorax are equally distant, but more shallow and less broad 

 than in A. fraud ulentus, and the scutellum is more sharply acuminate 

 at the apex ; the elytra are somewhat distinctly costulate, and the 

 pubescence is slightly denser ; the valves of the genital armature 

 although of somewhat the same shape as in A. fusculus, are more 

 robust, more widely open on the upper side from base to aj^ex. 



Length 10^ mm. ; width 5 mm. 



Hab. British Bechuanaland (Eamoutsa). 



Adoeetus picticollis, Fjihr., 



Plate XLI., fig. 22. 



Insect. Caffr., ii., p. 74. 



Colour, shape, and size of A. impurus ; distinguished from it mainly 

 by the shape of the clypeus and of the valves of the genital armature ; 

 the clypeus instead of being rounded in front is straight, then broadly 

 rounded till the median anterior part where it is distinctly emar- 

 ginate ; the sculpture of the head, prothorax, and elytra does not 

 differ also from that of A. mijmrus ; the suture of the elytra is more 

 broadly or more plainly infuscate, and the infuscate patch on the 

 prothorax is conspicuous ; the valves of the genital armature instead 

 of being narrow and tapering towards the apex and not much retuse, 

 are sub-vertical bi-partite from base to tip, the two parts are a little 

 more broadly separated on the upper than on the under side, sym- 

 metrical, parallel, truncate at the apex and with the outer angles 

 slightly spinose. The female cannot be distinguished from that of 

 A. invpurus and ^4. exasperans. 



Length 10-11 mm. ; width 4f-5^ mm. 



Hah. Transvaal (Johannesburg, Lydenburg), Orange Eiver 

 Colony (Bothaville). 



Adoeetus ingloeius, n. spec, 

 Plate XLL, fig. 23. 

 Pale testaceous, with the head infuscate and the suture of the 

 elytra slightly darker than the background (? immature) or fuscous- 

 brown with a slight metallic tinge and with the sides of the pro. 

 thorax broadly testaceous ; legs testaceous wath the anterior ones 

 slightly rusty red ; clypeus broadly rounded laterally, but not from 

 the base, plainly emarginate in the centre of the anterior part, and 



Adoeetus simulans, n. spec, pi. xliii., fig. 32. 



Almost similar to A. tessulatits, Burm. ; the vestiture is identical, and on the 

 elytra the three tessellate rows on each side are alike ; the female has the clypeus 

 also arcuate in front, but it is a little longer and more regularly curved from the 

 base, that of the male is nearly transverse and plainly emarginate in front, but not 

 incised as in the same sex of A. tomnlatu^. The shape of the genital armature is 

 quite different from that of the latter, and closely resembles that of A. separabili.s, 

 a very distinct species, but the opening is much more ovate, and the apical incision 

 is broader, deeper, and its apical angles sharper. Length 10-11 mm. ; width 

 5J-6 mm. 



Hab. Southern Rhodesia (Sebakwe).
