2.-Descriptions of New Species of Parasitic Hymenoptera chiefly in the Collection of the South African Museum, Cape Town. -By P. CAMERON.

FOR the opportunity of describing the following species I am indebted to Mr. L. Péringuey, the Keeper of Insects in the South African Museum. The present paper deals with the Cynipida, Evaniida, Stephanida, Braconida, and the Ichneumonida. Very little has been written on the South African species of these groups; hence it is not surprising that the collection contains many new species and some new genera. Thanks to the labours of Tosquinet and others, the Ichneumonide are better known. I have added the descriptions of a few species in my own collection. These are distinguished by being prefixed by an asterisk. Very few of the species are represented by more than one specimen. Fortunately most of them are females, which afford better specific characters than do the males-in, e.g., the length of the ovipositor.

FOENATOPUS, Smith.

FOENATOPUS ALBOMACULATUS, sp. nov.

Black, the flagellum of antennæ and tarsi testaceous, the base and apex of abdominal petiole narrowly marked with white, a transverse white spot on the base of the third segment; hind femora with a bluntly rounded tooth near the base, a longer, sharp one in the middle, a similar one half-way between it and the apex; two shorter, blunter ones between them in the middle, and a blunter, broader one behind the apical large tooth. Wings short, hyaline, the nervures and stigma black. የ .

Front closely, regularly reticulated; fore part of vertex opaque, irregularly, weakly reticulated, the hinder opaque, irregularly, transversely, closely striated, with an indistinct longitudinal furrow in the middle; the five spines stout, rufous below. Clypeus and a large spot on the malar space whitish-testaceous; base of mandibles broadly rufous. The third and fourth joints of the antennæ are almost equal in length; the following two are longer. Pronotum not quite twice longer than the width at the apex, irregularly, transversely striated on the narrowed basal part; the dilated apical weakly, irregularly reticulated. Mesonotum weakly, irregularly, transversely reticulated at the base; the sides irregularly, obliquely striated. Scutellum smooth, opaque. Metanotum with round, clearly separated punctures. Metapleuræ very minutely reticulated. Hind coxæ about three times longer than wide, opaque, coarsely aciculated; the base obscurely reticulated, the apex more or less striated.

The radial cellule is open at the apex, the radius becoming faint towards the apex of the wing; its base is thickened; there is a large whitish spot at the base of the stigma; the cubitus is entirely obliterated; the transverse basal is distinct, as is also the transverse median, with which it is interstitial; at the latter is a discoidal cellule, closed at the apex. Mesopleura not separated by a furrow. Abdominal petiole nearly as long as the thorax; the second segment becomes gradually wider towards the apex; the others are broader. The nervures are somewhat as in Stephanus insignis as figured by Schletterer (Berl. Ent. Zeit., xxxiii., f. 4, Taf. 1), but with the apical ones fainter, almost obsolete. Behind the head tubercles is a raised, stout, red transverse keel.
