Descriptions of Species of Parasitic Hymenoptera. 225 



neither Brull6's descriptions nor figures are remarkable for extreme 

 accuracy, as has been more than once pointed out, the chances are 

 that an examination of Brulle's type in the Paris Museum will show 

 that my suspicion of the identity of Ctenotoma and Macrogaster is 

 well founded. 



The species of Macrogaster I described (Manchr. Memoirs, vol. 43, 

 1898-99, pp. 193-201) from the Khasia Hills belong to a new genus or 

 genera, but not to the Hemig aster ini. So far the genus Ctenotoma, 

 in the sense I use it, is an African one, containing at present four 

 species, namely, rufipennis, Brull6, fuscipennis, Cam., nigriceps, 

 Cam., and ruficeps, Cam.
