and Northern Rhodesia respectively by Messrs. R. W. Jack and 

 LI. Lloyd (see below, p. 126). 



As regards Hymenoptera, at Bukama (Belgian Congo), in 1911, 

 Dr. Bequaert, of the Mission Scientifique du Katanga, met with a 

 small Hymenopteron which is a specific parasite of Glossina palpalis 

 pupae. The insect, which is a member of the genus Conostigmus, 

 Dahlbom (Family Proctotrupidae), received from its discoverer (Rev. 

 Zool. Afric., Vol. ii., Pt. 2, p. 255, 1913), the name Conostigmus 

 rodhaini : the female measures 18 to 20 mm. in length and the male 

 18 mm. On 24th June 1911, from a single pupa of Glossina palpalis, 

 collected in a breeding place on an island in the Lualaba, near Bukama, 

 Dr. Bequaert obtained six specimens (five females and one male) of 

 this parasite, which must indeed be very rare, seeing that out of a large 

 number of pupae found at the same spot no other was parasitised. 



Some interesting particulars with reference to parasites of Tsetse- 

 fly pupae are to be found in the Bulletin of Entomological Research, 

 Vol. V, Part 4, and Vol. VI, Part 1 (March and June 1915).

The following is extracted from a summary of a report by the late 

 Mr. R. A. F. Eminson (50) upon work done by him from May to July 

 1914, in studying the bionomics of Glossina morsitans in Northern 

 Rhodesia. " In a batch of 258 collected Glossina pupae, from one 

 puparium there emerged, on the 21st June 1914, a wingless parasitic 

 wasp of the genus Mutilla. It was observed that the wasp on emerging 

 had broken open the puparium in precisely the same way as would the 

 fly itself, so that a mere external examination of the case would not 

 reveal the fact that the fly pupa had been parasitised. On investi- 

 gating a number of pupa-cases collected in the field, four were found to 

 contain remains of parasitic pupae which were probably referable 

 to the same species of Mutilla. On 21st August, 84 of the tsetse 

 pupae were still unhatched, and seven of them were therefore opened.
