Dcscr'iptions of New Species of Parasitic Ilymenoptcra. 23 



strongly rugosely punctured, the centre with a distinct keel reaching 

 from near the base to the apex. Propleuroe closely transversely 

 striated ; the meso- irregularly reticulated ; the meta- closely 

 rugosely punctured. Front discoidal cellule longish, lanceolate at 

 the apex ; the posterior one-fourth shorter than it, narrowed 

 behind. Hind metatarsus shorter than the other joints united. 



This species should be readily known from the other South 

 African species of the genus by the long head, well developed 

 behind the eyes, long collar, closely striated mesonotum in one 

 piece, the middle lobe not being separated from the lateral, by the 

 stout keel down the centre of the metanotum, and by the antennae 

 being placed above the middle of the eyes. 



Gasteruption pulchripenne, sp. nov. 



Black, the antennae from the third joint, the four anterior femora, 

 tibiae and tarsi, the inner and lower side of the hind femora, base of 

 hind tibiae broadly, and the hind tarsi, the whole of the first and the 

 greater part of the second abdominal segments, red ; wings hyaline, 

 the apex of both violaceous, the nervures and stigma black. Base of 

 mandibles broadly red. $ . 



Length 15 mm. ; terebra 11 mm. 



Cape Colony. Hex Eiver ; Worcester Distr. 



Head shagreened, the face and clypeus covered with a white 

 down ; the clypeus in the middle fringed with golden hair. Malar 

 space rufous, as long as the pedicle of the antennae. Ocelli placed 

 behind the eyes, the hinder separated from them by about the same 

 ■distance as they are from each other. Centre of clypeus with a 

 broad shallow incision. Temples long, fully longer than the space 

 between the hinder part of the eyes ; roundly, gradually narrowed 

 behind. Occiput transverse. Pronotum with a distinct furrow, 

 bordered by keels down the centre ; it is irregularly transversely 

 striated. Mesonotum closely, transversely reticulated ; its base 

 broadly rounded ; the scutellum more strongly reticulated, depressed. 

 Metanotum irregularly reticulated in the centre, and bordered by a 

 furrow ; the sides smooth. Pleurae closely rugosely punctured and 

 more or less reticulated. Metanotum more strongly reticulated, the 

 •centre with a smooth line, which is narrowest above. 



Gasteruption crassiventre, sp. nov. 

 Black, the sides of mesonotum, and more or less of the pleurae 

 rufous, the middle of the abdomen largely ferruginous; the oral
