 September 1919.] 



This popular account of biting insects, etc., in British Guiana records 

 a tick, probably Aniblyomma americanum, L., the bite of which 

 causes intense irritation and swelling, and often produces ulceration. 

 Applications of kerosene oil or gasolene cause the tick to drop off 

 in the course of time. Trombiciium sp., a mite known as " bete rouge," 

 causes intense irritation often resulting in blood poisoning and nervous 

 exhaustion. Attacks may be prevented by the application of grease 

 to the feet and legs as far up as the knees before traversing grass- 

 land suspected of harbouring these mites. 



Tabanid flies include Chrysops tristis, ¥., Diachlorus scutellatus, 

 Mcq., D. curvipes, F., and Dicranomyia cervus, Wied. Mosquitos 

 include Stegomyia fasciata, F. {Aedes argenteus, Poiret) and Taenior- 

 hyncJms (Mansonia) titillans, Theo. Pulex irritans, L., is very abundant 

 in Indian camps in the far interior. Phthirus pubis, L., is also found 

 in abundance among natives. 



Jack (R. W.). Operations against Tsetse Fly in Southern Rhodesia. — 



Rhodesia Agric. Jl., Salisbury, xvi, no. 4, August 1919, pp. 292- 

 298, 1 map. 



Investigations with a view to ascertaining the possibility of checking 

 the advance of tsetse-fly [Glossina morsitans] in Southern Rhodesia 

 are being carried out during 1919, including organised shooting 

 operations. The various possible methods of combating the fly are 

 discussed [see this Review, Ser. B, vii, p. 9] and conditions governing 

 the selection of the adopted measures are described [loc. cit., p. 36]. 

 A map is given showing the recent advance of the fly along the 

 Shangani river and indicating the boundaries of the organised and 

 free shooting areas.

HoPKiRK (C. S. M.). Louse infesting the Legs of Sheep. — N.Z. Jl. 

 Agric., Wellington, xix, no. 1, 21st July 1919, pp. 15-16. 



Haematopinus pedalis is reported from New Zealand as infesting 

 the legs of sheep. The same louse was found on sheep in 1911 but 

 was then recorded as H. microcephalus, this name being a synonym. 

 It has seldom been noticed since. Eggs were found adhering to the 

 first locks of wool above the hock of the hind legs. The lice do not 

 apparently interfere with the general condition of the sheep and 

 there is very little irritation. Unaffected sheep become infested
