narrower than the thorax, the temples short, obhquely narrowed. 

 Clypeus not separated from the face, its apex broad, transverse ; 

 labrum broad, projecting. Upper tooth of mandibles much longer 

 than lower. Areolet almost 5-angled ; the transverse median 

 nervure received shortly beyond the transverse basal ; the wings 

 are clear hyaline. Abdomen short, not much longer than the head 

 and thorax united, bluntly pointed at the apex ; the keel on the 

 second and third segments. In the ? the antennae are short, stout, 

 dilated, and compressed beyond the middle ; three-coloured, ringed 

 with white in the middle ; in the <? they are serrate. There are 

 seven abdominal segments in the $ ; the last is nearlj' as long as 

 the penultimate; the ovipositor is broad, long, largely projecting; 

 the cerci distinct. Claws large, curved. Sutures between the 

 abdominal segments not constricted; they are almost smooth. 

 Basal joints of flagellum long. 



It is not clear to me whether this genus should be referred to the 

 Juppini or to the Aviblijpi/yi ; there does not appear to be a clear 

 line of demarcation between the two. The metanotum is too regu- 

 larly areolated for the Joppini. In the four species I have included 

 in the genus, the areola is different in form and size in each species. 

 The colouration — almost uniformly luteous — is identical, or almost 

 so ; the wings are hyaline, and, in the two known females, the 

 antennae are three-coloured.

Luteous, the six to eight basal joints of antennae luteous, the ninth 

 to thirteenth or fourteenth white, the rest black above ; brownish 

 below ; the eye orbits lemon-yellow ; wings hyaline, the stigma pale 

 fuscous, the nervures of a darker fuscous colour. Areola about one- 

 third longer than broad, its apex transverse, the base in the middle 

 transverse, the sides rounded; it is closely punctured and finely, 

 irregularly striated, the apex with a few longitudinal striae ; the other 

 areae are closely, finely punctured, the posterior median finely trans- 

 versely striated. ? . 



Length 7-8 mm. 



Cape Colony. 



Head, except the apex of the clypeus, closely punctured, as is 

 also the thorax, except the scutellum, which is smooth and shining. 

 The scutellar keels are strong on the sides, weak round the apex. 

 Centre of post-petiole shining, almost impunctate ; the sides 

 strongly, closely aciculated, with a few punctures on the apex ;
