Some Diptera from Eritrea, said by the natives to transmit trypano- 

 somiasis of the horse, ox and camel, inckided Hippobosca camelina. 

 Leach, H. macidata, Leach, Auchmeromyia luteola, ¥., and Mydaea sp. 

 Of these, the two Hippoboscids only can be really incriminated. The 

 collection also contained two species of Gastrophilus, said by natives, 

 to transmit African horse sickness. One of these is a new species, 

 caught on a native mule, and is described under the name Gastrophilus 

 magnicornis. A bibliography of twelve works is appended to this 

 paper.

 habitations. [To drive flies out of our houses.] — C. R. hebdom.

 The method of driving flies out of rooms here recommended is based 

 on the reactions of house-flies to blue and green light. When exposed to 

 a blue light, the authors found that the flies first become restless, then 

 inactive, as in the dark. If therefore in rooms in which the light comes 

 from one side, the windows are filled with blue glass and provided at 

 intervals with moveable shutters, flies, being attracted to white light, 

 will not enter from the outside ; those which enter while the window^s 

 are open will either become inactive or quickly go out through the 

 shutters. The same principle can be applied to rooms lighted from 

 opposite sides ; in this case only one set of windows is opened at a 

 given time. Articles of food should be placed in cupboards, etc., 

 pro\dded with blue glass windows.

 les larves de Culicin6s pourvues d'un long siphon. [Remarks on 

 the larvae of Culex geniculatus and on Culichie larvae with long 

 siphon tubes.] — Bull. Soc. Path. Exot., Paris, ix, no. 7, 12th July

In various parts of France and in Tunisia Culicine larvae with long 

 and narrow respiratory siphons have been found in Anopheline breeding 

 places. Larvae taken in Brittany were bred out and proved to be those 

 of Cvlex geniculatus, 01., known to occur in France, Italy and Palestine. 

 These larvae have a strong resemblance to those of the North American 

 species, C. territans, Walk., which are also found associated with 

 Anophelines in clear, standing water. The larva of C. salinanus, Coq., 

 also resembles that of C. territans, though its siphon is stouter and it is 

 adapted to brackish water, though it lives preferably in permanent 

 swamps.

The rainfall in this district is very scanty and the streams are dry 

 except in the rainy season, but pools of brackish water are to be found 

 in those places where the subsoil water reaches the surface owing to
