agree in the two extremely important characters of the long 

 maxillary palpi and the short second abscissa of tb-:" radins. 



In H. Giffardi the second tergite is striate back to the 

 snlcns, differing in that respect from hahilis and desidemtus. 



This species resembles very closely Blosteres caudatu-s Sze- 

 pligeti from the same region, but differs by the longer maxil- 

 lary palpi, the more elongate stigma with the radius arising 

 distinctly beyond the middle and by the structure of the pre- 

 scutellar sulcus. 



This species was by far the most numerous in individuals of 

 the fruit fly parasites bred at Oloke Meji and attacked a 

 greater number of host insects and in a greater variety of 

 fruits than any others. It was carried in a living condition 

 to South Africa, but was unfortunately lost during the time 

 the author was confined in a hospital there. 



Like Diachasma Tryoni Cameron, D. FuUawayi and Opius 

 Imitanae, this spex^ies may pass a considerable period dormant 

 in the last larval instar. 



6. Hedylus clypeatus n. sp. 



5 Resembles H. desidcratus, but the mandibles are flattened and 

 expanded basally ; the clypeiis has a semicircular impression at api-x ; the 

 clypeus is a little produced in the middle above the impression and at 

 either side of it, giving a somevirhat tridentate appearance, it is some- 

 what tectiform about twice as wide as long; the facial ridye is flattened 

 and shining and the face is more' strongly punctured than in desidcratus ; 

 the (true) metanotum is dentate in the middle and the flrst tergite is 

 nearly smooth and shining, the thorax above is rufo-testaceous. The 

 anteiinae of the unique specimen are missing. 



Described from 1 9 specimen taken at Oloke ]\[eji, 

 !N^igeria, July 27, 1914, upon the fruit of an unknown vine, 

 which it was examining apparently with the intention of ovi- 

 positing. These fruits contained fruit fly larvae, which un- 

 fortunately failed to breed out, and no more were c'iitained.
