Hymenoptera. 231 



convex, clearly raised above the mesonotutn, broader than long, 

 rounded at base and apex ; the sides keeled to near the 

 middle of the apex. Areolet 5-angled, the nervnres 

 converging closely in front : recurrent nervure received l:)ehind 

 the middle ; transverse median nervure interstitial. The petiole 

 becomes gradually wider from the base to the apex, the post- 

 petiole not being clearly defined. Gastracoeli moderately deep. 

 Antenna? shoi-tly, densely pilose, the ord joint slightly longer than 

 the -1th. Abdomen with (S segments. Tarsi not spinose. 



The species <>n which this genus is founded looks more like 

 one of the South African Cri/pf/iKf tlian an IchneuDion. The 

 absence of an areola and clearly tlehned basal are;f on the 

 metanotum shows also an approach to Cryptina ; l)ut the 

 absence of pleural and mesonotal fui-rows separates it from that 

 group. 



It comes nearest to Platylabris, which has a clearly dehned 

 areola and other areae on the metanotum.

Head and thorax rufous, a broad l)and of ecjual width in the 

 centre of the vertex and front, the occiput excei)t round I he 

 edges, the sutures of tiie thorax and a broad band in the centre of 

 the basal half of the mesonotum black. Abdomen black, the r)th 

 and following segments white, slightly tinged with l>Iue. Four 

 front legs dark rufous, the hind coxa3 and trochanters largely 

 l)lack : the femora rufous, black at the apex, the tibiae and tarsi of 

 a darker red, the former broadly blackish at the apex. Antennal 

 scape red, the rest black, densely' covered with short black })ije. 

 Wings clear hyaline, the nervures and stigma black.

Grahamstown. May. Dr. Schonland. 



Head and thorax closely, strongly punctured ; the metanotum 

 is more coarsely rugose ; the upper part of the meta- 

 pleurae at the apex is irregularly reticulated ; there is a square 

 black mark in the centre at the base. The basal abdominal 

 segments are aciculated : the apex of the 1st and the base of the 

 2nd appear to be finely, closely reticulated. The apex of the 

 disco-cubital nervure and the 2nd transverse cubital are largely 

 buUated ; the former is angled in the middle.
