is explained by the presence, in the centre of the infection, of numerous 

 Anopheles nmculipennis and a few chronic malaria cases. Great 

 impetus was given to the epidemic in the n\onth of August owmg to 

 the precocious production of gametes observed in the blood of recently- 

 infected persons. This is an important symptom, indicating the 

 necessity of dealing promptly with any cases of primary malaria ni 

 Moroccan towns, particularly in those districts where it is possible to 

 contract malaria. The quotidian type predominated, though the 

 intermittent type also occurred. Quinine was found to have an excellent 

 effect on any of the parasites concerned. Plasmodinm, vivax occurs 

 in the proportion of 43 per cent. ; P. falciparum, 33-1 per cent. ; and 

 the two associated in the proportion 18-8 per cent.

The breeding of Glossiiui morsitans and G. imlfalis from pupae 

 brought by the author from Senegal and reared in mushn cages at the 

 Pasteur Institute in Paris, was begun in 1914 and has previously been 

 described [see this nevieiv, Ser. B, iii, p. 77]. The examples of G. palpalis 

 unfortunately died out almost at once, but the rearing of G. morsitans 

 has continued satisfactorily for three years, the strain ultimately 

 dying out naturally owing to an unusual preponderance of males and 

 absence of females! Details of the construction of the breeding cages, 

 feeding experiments, etc., are given, and records made of longevity, 

 reproduction, etc. An unsuccessful attempt was made to infect some 

 of the Glossirm with strains of Trypanosoma rhodesiense and T. brucei 

 from Uganda. Experiments in parasitisation of the pupae of 

 G. morsitans by the Chalcidid, Nasonia brevicornis, are described in 

 the next paper. 



This attempt has proved that Glossina can be reared in Europe 

 and biological experiments attempted under the same conditions as 

 in tropical countries. It is hoped by this means to elucidate many 

 hitherto obscure details of the life and pathogenic role of these insects, 

 which it is not always possible to do in tropical laboratories.

Nasonia brevicornis, Ashm., is known to parasitise the pupae of 

 various Muscids throughout the world. It has been observed that in 

 attacking the pupa of its host the parasite makes a number of 

 punctures and sucks up the liquid which issues from the wounds.
