Scmnop)hrys, Poer. ; it may be known from the present genus by 

 its very broad head and by there being a horn between the antennae. 



■'- Ehynchexetastes violaceipennis, sp. nov. 



Rufous, the antennae, the occiput, vertex, front broadly, a large 

 mark on the sides of the clypeus, malar space except in the centre, 

 the mesonotum, except a curved line, widest at the base along the 

 sides, a transverse mark, wider than long, of equal width and length, 

 propleurae except narrowly at the base, mesopleurae except for an 

 irregular, somewhat pyriform mark (the narrowed end in front) at 

 the apex below, the breast, a narrow line along the base of the 

 metapleurae, two streaks on the apical half of the first abdominal 

 segment, two broader ones, dilated at the apex, on the second, the 

 third except at the sides, and the whole of the others, black. Legs 

 coloured like the body, the apex of the hind tibiae and the hind tarsi, 

 except at the base and apex, black. Wings uniformly fuscous 

 violaceous, the nervures and stigma black. ? . 



Length 12 mm. 



Cape Colony. 



Head closely punctured ; the labrum is of a paler, more yellowish 

 hue and is much less distinctly punctured ; the rufous colour of the 

 mandibles has a yellowish tint ; the teeth are black. Palpi fuscous. 

 Pro- and mesothorax closely punctured, the punctures distinctly 

 separated ; the metapleurae punctured like the mesopleurae ; the 

 metanotum closely rugosely punctured, striated in the middle. 

 Abdomen smooth and shining. 



ALLOTHECA, gen. nov. 



Metathoracic spiracles small, oval. Basal third of abdominal 

 petiole narrowed, the apical part dilated; the basal part of it becomes 

 gradually wider, the apical (and larger) is of equal width ; the other 

 segments are not much compressed. Parapsidal furrows obsolete. 

 Clypeus not separated from the face, its apex bluntly rounded. 

 Malar space long, not quite so long as the antennal scape. Eyes 

 parallel, not emarginate within. Scutellum roundly convex. Meta- 

 notum with the apex widely and deeply depressed. Areolet 4-angled, 

 the nervures meeting in front. Transverse median nervure interstitial. 

 Sub-discoidal nervure originating below the middle of the recurrent 

 nervure. Disco-cubital nervure rounded in the middle, not broken. 

 Basal abscissa of radius roundly curved downwards ; the apical
