Cape Colony. Worcester Distr. Hex Eiver (January). 



Face strongly and closely punctured, the centre roundly raised ; 

 the top of the clypeus with some large, scattered punctures ; the 

 centre smooth ; the apex with a row of small punctures. Labrum 

 smooth, fringed with fulvous hair. Front and vertex strongly and 

 closely punctured. Mandibles rufous, as are also the palpi. Pi'O- 

 and mesothorax strongly and closely punctured ; the scutellum 

 sparsely punctured, smooth in the middle and at the apex ; the 

 lateral keels extend beyond the middle ; post-scutellum finely, but 

 not closely punctured. Median segment more closely, rugosely 

 punctured than the mesonotum ; the areola clearly longer than 

 wide, rounded at the base, the apex slightly turned roundly 

 inwardly ; it is stoutly transversely striated-reticulated ; the apex 

 has some stout longitudinal, keels. The base of the segment in the 

 centre has an oblique depression ; the apical slope is closely trans- 

 versely rugosely striated, the sides more strongly than the centre. 

 PleuraB closely, strongly punctured. Sides of post-petiole closely 

 punctured, the centre obscurely striated ; it is broad at the apex, 

 becoming gradually narrowed towards the base. The second and 

 third segments are closely punctured. Gastrocoeli deep, transverse, 

 the centre striated ; the space separating them is closely striated. 

 Areolet 5-angled, narrowed in front, the recurrent nervure received 

 shortly beyond the middle ; the transverse median nervure almost 

 interstitial. 



Antennae short, stout, thickened beyond the middle ; the basal 

 two joints of fiagellum longer than the others, of equal length. 

 Apex of clypeus transverse, broad, the lateral foveas large. Lower 

 side of tarsi spinose ; the apices of the joints with longer spines. 

 Temples wide, obliquely narrowed. Metanotal spiracles long, linear. 



The S has the antennae longer, the flagellum brownish, black 

 above, the inner orbits lined with yellow ; there is a narrower 

 yellow line in the centre of the outer. The scutellum is black, or 

 black and red, with the apex yellow ; the sides of the clypeus are 

 red, or yellow and red ; there is a narrow yellow line on the apical 

 half of the pronotum. The amount of the red and yellow colour on 

 the head and thorax probably varies in both sexes. The are£e 

 on the metanotum are all regularly defined. 



This is not a typical Platylabus. Comparing it with P. rufus, the 

 petiole is narrower and the post-petiole wider. Tosquinet describes 

 some large African species — 17-20 mm. in length.
