Descriptions of Neiu Species of Parasitic Hymcnoptera. 89 



Hind wings with the apical nervures entirely obliterated, i.e., 

 the radius and cubitus ; there is only one basal cellule. Face and 

 clypeus closely rugosely punctured, the punctures (especially above) 

 running into close reticulations, covered with white pubescence. 

 Mandibles broadly rufous at the apex. Front and vertex rugosely 

 punctured, more or less striated laterally. Thorax closely rugose ; 

 the upper part of the mesopleurae for the greater part longitudinally 

 striated, the striae more or less curved, stout. Scutellum flat, 

 coarsely alutaceous, without distinct punctures. Metanotum with 

 three basal areae ; the central is the smaller, and is open at the 

 apex ; the lateral open at the apex on the outer side ; the centre is 

 transversely striated. On the upper half of the base of the meta- 

 pleurae are a number of stout, irregular longitudinal striae, bordered 

 at the apex by a keel running from the top to the bottom. Abdominal 

 petiole not so long as the following three segments united, slender, 

 its apical third distinctly nodose. 



The eyes do not converge more below than they do above. 

 Clypeus not separated from the face. Temples very short ; the 

 occiput transverse. Tibiae and tarsi spinose ; the long spur of the 

 hind tibiae more than half the length of the metatarsus. Hind 

 trochanters shorter than the coxee, the basal joint on the outer side 

 shorter than the apical, longer on the inner. The eyes are distinctly 

 incised on the inner side. The hind tarsi are slender, the basal joints 

 not dilated. 



I am in doubt about the generic position of this species. The 

 eyes do not appear to be hairy, but this may be owing to the 

 pubescence having been rubbed off. The hind wings, too, are 

 more deficient in nervures than in typical Trichomma ; the hind 

 trochanters are shorter, the scutellum flatter, and the thorax broader 

 at the base than in that genus. The generic location must remain 

 in doubt until fresh specimens have been examined. The pubescence 

 on the eyes is liable to be rubbed off, as I find to be the case with an 

 Oriental species of Trichomma I have examined. 



? Trichomma caeiniscutum, sp. nov. 



Black, the four front legs, except the coxas, stramineous, the hind 

 legs, except the coxae and trochanters, rufous ; wings short, hyaline, 

 the nervures and stigma black. Abdomen red, the extreme base of 

 first segment, the upper part of the second, and the sixth and 

 seventh black. J . 



Length 10 mm. 



Natal. Frere.
