the other joints black ; head smooth ; prothorax amphate in the 

 anterior part, very Httle attenuate behind, and with the lateral part 

 of the base rounded from the posterior seta, margin recurved, disk 

 nearly smooth in the centre only and deeply aciculate all round, 

 lateral margin flavescent ; elytra oblong, nearly plane, very dis- 

 tinctly punctato-striate, with the intervals convex, outer margin with 

 a very narrow flavescent band. 



I have not seen the male of this species, which is probably a little 

 more slender and has a less rotund prothorax ; in the female the 

 lateral grooves of the anterior tarsi are not apparent. 



Allied to the preceding species, but easily distinguished by the 

 raised intervals of the elytra, the more rotund shape of the pro- 

 thorax, and the colour of the antennae. Length lOJ- mm. ; width 



4 mm. 



Hah. Zambezia (Salisbury). 



Platynus latipennis, Bohem., 

 Insect. Caffr., i., p. 169. 



Black, subopaque ; palpi and legs flavescent ; first basal joint of 

 antennae flavescent, the other four deeply infuscate and the others 

 light brown ; head smooth ; prothorax very broad, suborbicular, 

 lateral basal part rounded, outer margin recurved all round, and 

 narrowly flavescent, the whole disk roughly shagreened ; elytra 

 oblong, broader than the prothorax, plane, sinuate behind, finely 

 punctato-striate, intervals plane, outer margins very slightly 

 flavescent. 



Easily distinguished from the other species by the broad, rotund 

 prothorax, the whole upper part of which is conspicuously shagreened, 

 and by the more ovoid shape of the elytra. Length 11 mm. ; width 



5 mm. 



Hah. Transvaal (Leydenburg). 



Platynus geacilis, Bohem., 

 Insect. Caffr., i., p. 173. 



Black, or piceous red ; palpi and legs reddish ; antennae infuscate, 

 the basal joint piceous ; head smooth ; prothorax elongate, very little 

 ampliate laterally, only wider by one-fifth in the ampliated part than 

 at the base, outer margins recurved, edged with red brown, posterior 

 angle rounded, median part of disk smooth, the basal, and also the 

 lateral part, aciculate ; elytra elongate, oblong, not broader in the 

 male than the prothorax at its widest part, and hardly ampliate past 

 the middle, hardly sinuate behind, opaque, edged with a narrow, 

 rufescent band, narrowly striate, stri^ without punctures, intervals
