 2 to 21 miles from any habitation M. domestica was found associated 

 with Af. lusoria Wied. [aiistralis, Macq., feygusoni, J. & B.), M. 

 nebulo, F. {hilli, J. & B.), M. ventrosa, Wied. [nigrithorax, Stein),

 the Belgian Congo. — Ann. Trop. Med. & Farasit., Liverpool, 

 XV, no. 1, 27th April 1921, pp. 95-102, 6 figs. 



Glossina schwctzi, sp. n., and G.fusca var. congolensis,n., are described. 

 Tables are given to distinguish the genital armature of both sexes 

 of G. schwetzi and G. tahaniformis and of G. fiisca and the new variety 

 of it. 



Nevv'stead (R.) & SiNTON (J. A.). On a Collection of Pappataei Flies 



{Phlehotomiis) l£0VQ.ln6.m. — -Ann. Trop. Med. & Payasit., Liver- 

 pool, XV, no. 1, 27th April 1921, pp. 103-106. 



The species recorded are : Pklehotomus papata^ii, Scop., P. minntiis, 

 Rond., P. minutus var. antennatns Newst., P. sergenti, Parrot, and 

 P. major, Annandale. With the exception of the last-named, which 

 was taken at Simla, numerous examples of all these species were 

 caught in the north-west Provinces. 



The difference in the antennal segments upon which the erection 

 of a new species P. antennatns [R. A.E., B, 1, 34] was based, can no 

 longer be considered of specific importance ; this is therefore now 

 treated as a variety of P. minutus.

 JL, Salisbury, xvin, no. 2, April 1921, pp. 188-190. 



The commoner causes of loss of cattle by arsenical poisoning are 

 enumerated, and can be avoided if the following precautions are 

 taken. 



All drums containing the dip when in use should be carefully super- 

 vised and kept locked up. Empty drums should be washed, and the 

 refuse buried. The capacity of the dip tank should be known in order 

 to adjust the strength of the solution before dipping. Draining pens 

 should be so constructed that dip cannot collect in them, and drying 

 kraals efficiently drained to prevent accumulation of arsenic. Cattle 

 should not be given access to land that has been splashed or saturated 

 with the dipping solution, and should be prevented from drinking 

 contaminated water. Tanks liable to flooding or overflowing should 

 be protected by drains.
