and cubitus in hind wings extending to the apex ; the pobrachial 

 large, much widened at the apex. Parapsidal furrows deep, distinct. 

 Eyes large, bare ; malar space not half their length. Lower part of 

 front keeled round the antenmie. 



TJie antennae are stout, slightly longer than the body, the third 

 joint longer than the fourth. Ovipositor not projecting. There 

 ai-e three stout keels on the base and middle of back of abdomen, 

 the outer commencing at the sides and united to the central by 

 transverse keels. Eadial cellule short, its apex much narrowed, 

 through the apical abscissa of the radius curving up to the costa. 

 Cheeks sharply margined. The ocellar region is raised ; broadly 

 depressed in the middle behind, the lateral angles forming sharp 

 teeth behind the ocelli, which are placed on the edge of the occiput. 

 The first abscissa of radius is very short. 



The 3^ is similar in the main ; the ventral segments are produced 

 into a stout projection, clearly separated from the rest in the middle, 

 and composed of at least five segments, ending at the apex in two 

 cerci ; the genital valves are large, broad. 



The recurrent nervure entering the first cubital cellule places this 

 genus near Ascogaster and Gastrotheca ; the latter may be known by 

 the bidentate apex of the abdomen and interstitial transverse basal 

 nervure ; Ascogaster by the apex of the abdomen not being serrate, 

 the subtriangular second cubital cellule, and by the absence of a 

 closed cellule at the base of the hind wings. The present genus 

 should be easily known by the bidentate vertex, distinct parapsidal 

 furrows, keeled metanotum and abdomen, serrate apex of abdomen, 

 and by the large cellule in the base of the hind wings.

Kufo-testaceous, the head, except the labrum and palpi, antennae, 

 prosternum, apex of pronotum in the middle, the apex of the first 

 and the whole of the other joints of the hind tarsi, black ; wings 

 fuscous, the costa, stigma, and nervures black. ? and g .

Cape Colony. Stellenbosch Distr. 



Middle of face strongly, the sides more weakly punctured, the 

 centre of the face raised, bordered by a deep, moderately wide 

 furrow ; the clypeus is more finely and closely punctured. On the 

 front (which is shining) there is a curved keel round each antenna, 

 a less distinct one down the centre, and a short, indistinct one on 

 the sides. Occiput and cheeks margined sharply. Mesonotum and
