species, in addition to two other parasitic Hymenoptera Dirhinus 

 inflexus, Wtst., and Coelalysia glossinophaga, Turn. from pupae of 

 G. morsitans form submorsitans obtained by him at Larabanga in the 

 same Colony. Experiment showed that C. amenocles parasitised pupae 

 of Sarcophaga much more readily than those of Glossina. " As species 

 of Sarcopliaga are everywhere abundant around villages," writes 

 Simpson, " and as they breed prolifically, it would be possible in a 

 very short time to obtain very large numbers of these parasites for 

 dissemination." 



Within the last few years several Hymenopterous parasites of the 

 pupae of G. morsitans, in addition to those already mentioned, have 

 been described by Messrs. Turner and Waterston. The following is a 

 complete list of the parasites of Glossina pupae known in 1922, omitting 

 Syntomosphyrum glossinae, Wtst., which, as already stated, has been 

 proved to be a hyperparasite of Mutilla glossinae, and therefore 

 harmful instead of beneficial. 



In view of the importance of the subject, investigators would do well 

 to turn their attention to the parasites of Glossina pupae, and the 

 breeding out of the pupae of the different species of Tsetse-flies would 

 doubtless lead to interesting discoveries. For the propagation of 

 these parasites it would perhaps be possible later on to employ the 

 methods successfully adopted by the Americans, for the multiplication
