• agree in the two extremely important characters of the long 

 maxillary palpi and the short second abscissa of the radius. 



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

 snlcns, differing in that respect from hoJbilis and desideratus. 



This species resembles very closely Biosteres caudatus 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 Diacliasma Tnjoni Cameron, D. Fullawayi and Optus 

 lantanae, this species may pass a considerable period dormant 

 in the last larval instar. 



6. Hedylus clypeatus n. sp. 



9 Resembles H. desideratus, but the mandibles are flattened and 

 expanded basally ; the clypeus has a semicircular impression at apex; the 

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

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

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

 and shining and the face is more strongly punctured than in desideratus ; 

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

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

 antennae of the unique specimen are missing. 



Described from 1 9 specimen taken at Oloke Meji, 

 Nigeria, 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- 

 fortmiately failed to breed out, and no more were oljtained.
