deep, longer than wide, curved and narrowed at the apex ; the centre 

 with some striae ; the part between them wide, indistinctly striated ; 

 the second segment is longer than the others — about one-fourth 

 longer than the third. Ovipositor long, black, projecting. Areolet. 

 5-angled, receiving the recurrent nervure shortly beyond the 

 middle ; transverse median received shortly beyond the ti'ansverse 

 basal. 



This seems to be a genuine Exephanes ; it may be separated from 

 E. rufulus, Tosq., thus : — 



Pleurae rufous, metanotum without black, the spiracles 



oval; areola semi-oval nifiilun. 



Pleurae black, metanotum black in the middle, the spiracles 



linear, areola long nifiromacuhitus.. 



I have in my collection from Natal a species which more re- 

 sembles E. rufulus in size and colouration, but differs from the 

 latter in the areola not being "semi-oval"; from nigromaculatus 

 in the pleurae and metanotum not being marked with black ; and 

 from both in the apex of the abdomen being yellowish-white.

Eufous, the eye orbits narrowly and the sixth to eight abdominal 

 segments pallid yellow ; antennae rufous, the eleventh to sixteenth 

 joints white, the apical black ; wings hyaline, the nervures and 

 stigma black ; the areolet almost 4-angled, the nervures almost 

 meeting in front, the recurrent nervure received almost in the 

 middle; the transverse median nervure interstitial. $ .

Face finely punctured, more sparsely on the raised central part • 

 the clypeus more sparsely punctured above ; its apex impunctate. 

 Labrum projecting, yellow. Mandibles rufous, the teeth blacky 

 Palpi pale rufous, tinged with yellow. Temples obliquely narrowed. 

 Pro- and mesothorax closely, but not strongly punctured. Scutellum 

 shining, with only a few punctures in the middle. The median seg- 

 ment is more closely and strongly punctured than the rest of the 

 thorax ; the areola is about twice longer than wide, open at the base, 

 the apex rounded inwardly ; it is about twice longer than wide ; 

 narrowed from shortly beyond the middle to the base and to a less 

 extent towards the apex ; the basal lateral area is as wide at the 

 apex as the length on the outer side, its base wider than the apex ; 

 the second is twice wider on the outer than on the inner side ; the
