On some South African Iclineumonidae. 385 



beneath, white. Wings hyaline with the stigma, nervures, and a 

 transfascia including the whole basal nervure, black. Length 13, 

 terebra 11, mm. A typical member of this distinct genus, most closely 

 allied in abdominal sculpture to the Indian X (EpirJiyssa [sic]) 

 anmtlicornis, Cam. 



It was captured at Mfougosi in Zululand by W. E. Jones during 

 December, 1914. Two co-types in the British Museum are from Zulu- 

 land in 1865 and ex coll. Distant from Durban, taken by Bell Marley.

ACAENITUS BIVITTATUS, Sp. nOV. 



$ only. A testaceous species with the flagellum, inandibular apices, 

 clypeal foveae, disc of the scape, of the head, of the mesonotum except 

 two vittae, and of the fifth to seventh segments, black. Head closely 

 punctate with the clypeus basally discreted, apically bisinuate and 

 centrally a little produced ; meta thorax glabrous, with the basal area 

 indicated ; scutellum convex and obsoletely punctate ; basal segment 

 glittering and impunctate, discally sulcate, with spiracles before its 

 centre. Hind legs desimt. Wings ample and deeply flavescent, with 

 only the apical margin of both pairs inf umate ; stigma small and, like 

 the nervures, testaceous ; upper basal nervure straight and postf urcal ; 

 nervelet distinct ; intercubital uervure not short, f enestrate below and 

 continuous with the bifenestrate recurrent ; nervellus centrally inter- 

 cepted. Length, 11 mm. Of Tosquinet's species the present is most 

 closely allied to A. Germanus.

One female of this common African species is labelled Delagoa Bay. 

 In the British Museum it is represented from Cape Colony and Natal ; 

 a female from the latter is labelled " Parasite on a Saturnia, Port 

 Natal." I by no means agree with Cameron (Ann. S. African Mus., 

 1907, p. 224) that this genus is synonymous with Macrogaster, Brullt'.
