Black, iridescent on the upper part ; legs, palpi, labrum, and the 

 basal joints of antennae dark red, the other joints ferruginous ; head 

 smooth ; prothorax also smooth, nearly straight, and without 

 sinuation laterally, but a little narrower in front than behind, and a 

 little convex on the disk for two-thirds of the length ; anterior margin 

 very slightly sinuate, posterior one straight ; elytra as broad as the 

 prothorax, convex, oblong, a little sinuate apically, narrowly but 

 deeply striate, intervals smooth, no puncture on the third interval. 

 The posterior supra-orbital seta is very long. Length 7-8 mm. ;

 Feronia (Argutor) amce^nula, Insect. Caffr., i., p. 180. 



Head, palpi, and legs light ferruginous ; prothorax pale red ; elytra 

 fuscous black with two large ferruginous patches on each side, 

 sufficiently large as to make them appear to be ferruginous with a 

 cruciform dorsal black band ; head smooth ; prothorax similar in 

 shape to that of A. trivialis, the median longitudinal line very faint ; 

 elytra oblongo-ovate, convex, striate, the striae moderately deep and 

 punctulate ; under side piceous red or dark ferruginous. Length 

 5 mm. ; width 2 J mm.

 it is long and sharp), lateral lobes sloping inwardly (P. dichrous) 

 or perpendicular (P. hottentotus, caffer, &c.) ; ligula long, carinate 

 in the middle, sinuate at tip ; paraglossae disconnected from it near
