A table distinguishing the larval and pupal characters is given, 

 and the technique employed in removing the larvae and preparing 

 them for identification is explained.

In Korea, the adults of Musca domestica, chiefly the females, survive 

 throughout the winter if fed. The flies are not in a state of hibernation, 

 active movement and oviposition occurring at times. 



Some authors maintain that living pupae are found in the winter, 

 while others say it is impossible to keep them. The author's experi- 

 ments in this connection show that in an ordinary room temperature 

 the pupae emerge after a few weeks, while the larvae can hardly 

 develop under these conditions. Experiments showed that the eggs 

 are the least resistant to low temperatures, the larval and pupal 

 stages being next, and the adults the most resistant. Outdoor tempera- 

 tures prevent M. domestica from breeding in the winter. Stomoxys 

 calcitrans, Sarcophaga carnaria, and Fannia canicularis hibernated 

 in the larval and pupal stages at a room temperature. 



Observations on adult flies under natural winter conditions are as 

 follows : — In Seoul it is probable that there are certain places where 

 M. domestica breeds continuously in the winter, but there are no exact 

 data confirming the overwintering of larvae and pupae. Scatophaga 

 sfercoraria and Calliphora lata may overwinter in the adult stages. 

 Larvae and pupae were collected in Keigo, and breeding experiments 

 show that the following species overwinter in those stages : Stomoxys 

 calcitrans, Sarcophaga carnaria, Fannia canicularis, Sepsis sp. and 

 (?) Ophyra nigra.

The species described include Haematopota {Chrysozona) Iambi, 

 sp. n., from Beausset (Var). At Montpellier a variety of H. bigoti, 

 Gob., is frequently met with, for which the author suggests the name 

 var. monspellensis, n.

This is a study of the situation as regards sleeping sickness throughout 

 the large region of the Middle Congo, and a general review of the present 

 status of the disease on the lower Ubangi and its tributaries is given. 

 It is not considered possible as yet to determine whether regular 

 atoxyl prophylaxis, carried on in each zone for 16 or 18 months, can 

 be said to have been successful.
