42 P. CAMERON. HYMENOPTERA I. 



being confluent with the base of the radial ; the stigma is large, broadly rounded behind, 

 somewhat twice longer than its breadth in the middle; the radius originates frorh its middle. 

 The transverse basai nervure is widely broken in the middle by the white cloud, as is the 

 transverse médian on the posterior part; the lanceolate cellule appendiculated. The hind 

 wings are hyaline, the apex broadly infuscated. The last abdominal segment has a distinct 

 smooth pygidial area; its apex projects obliquely; the 2 nd abdominal segment is as long as 

 the following tvvo united ; the y d , 4 lh and 5 th shorter than the follovving. The hind tibiae 

 are more stoutly serrate than usual. 



This is not a typical Oryssus as that genus is now limited.

Black, the head, thorax and coxae densely covered with white pubescence, the abdomen 

 smooth and shining, its pétiole coarsely rugosely punctured, the punctures running into stria- 

 tions towards the apex; wings clear hyaline, the nervures and stigma black; the récurrent 

 nervure received shortly beyond the transverse cubital. Sides of metanotum broadly rounded, 

 the centre depressed, the edges of pronotum sharply angled. cT- 



Length 8 mm. 



The punctures on the front run into reticulations, which are more distinct in the centre 

 than on the sides; the lower part of the face is more or less reticulated ; the upper is rugose, 

 with a not very strong keel down its centre. Eyes slightly converging above. The hinder 

 ocelli are separated from each other by a distinctly greater distance than they are from the 

 eyes. Apex of mandibles smooth and shining, the rest opaque, pilose and distinctly, but not 

 closely, punctured. Palpi black, covered with a white pile. Malar space not furrowed, nearly 

 as long as the antennal scape. Basai two joints of antennae nearly as long as the scape and 

 equal in length. Occiput distinctly margined. Temples hardly narrowed. Parapsidal furrows 

 obsolète. Scutellum more closely punctured than the mesonotum ; there is a distinct transverse 

 furrow at its base ; its apex is rounded and it is separated from the médian segment by a 

 wide and rather deep furrow. Médian segment densely covered with white pubescence ; its 

 centre, at the apex widely hollowed, the dépression narrowed at the top and bottom. Pro- 

 and mesopleurae bearing large, round, clearly separated punctures, the former stoutly striated 

 below; the latter with a large smooth, shining space above. The base of the metapleurae is 

 irregularly striated; the centre with round, clearly separated punctures; beyond this it is 

 widely, irregularly reticulated, the reticulations are continued round the sides of the apex; 

 the hollowed centre is irregularly widely striated. Mesosternum coarsely punctured. Metasternal 

 process diverging, the forks fully twice longer than wide and rounded at the apex. Tibiae 

 clearly spinose, the tarsi more minutely so ; the long spur of the hind tibiae does not reach 

 to the middle of the metatarsus. Hind coxae rugosely punctured, smooth at the base. Base 

 of pronotum sharply angled.
