owing to the size of the farms. Dippino; had not been practised there. 

 All cattle movement was regulated by permit. No cattle were allowed 

 to be brought from endemic areas before they were eighteen months 

 to two years old. These were placed in a slightly infected area and if 

 they survived for about six weeks to two months they were branded 

 and granted permission to trek throughout the country. This system 

 had worked exceptionally well. 



Mr. Sinclair stated that he considered it inadvisable to make any 

 alteration in the quarantine regulations, and this opinion was supported 

 by Mr. Gray, w^ho pointed out that there was still much to be learnt 

 about the disease. So far as was known, no Coast Fever existed in 

 North-Eastern Rhodesia ; in the northern portion of Nyasaland 

 it was reported to be endemic.

 \^y. hovis, De Geer, in Canada, Canadian. Entoinologisf, London, Ont..

In the early w-ritings on the w'arble-fly occurring in the United States 

 the species was referred to as Hypoderma hovis. In 1891 Curtice 

 concluded that the American species was H. lineata, Vilhers, and from 

 this time until 1912 subsequent W'Orkers have referred only to H. lineaki 

 in speaking of the North American species. During the summer 

 of 1912, Dr. Hadwen discovered the common species of fly in Canada 

 was H. bovis and not H. lineata [see this Review, Ser. B, i, p. 6(>]. 

 AYork since this time has shown that H. bovis is widely distributed 

 in Canada and it is probable that it occurs with H. lineata in the United 

 States. The economic importance of this species renders the state 

 of uncertainty as to its presence or absence all the more remarkable. 

 The adults of the two species have good distinctive characters.

new Enemy of Musca domestica. — Canadian Entomologist, London,

The observations made by G. E. Sanders w'ould iiidicate that 

 Scatophaga stercoraria destroys numerous other Diptera, especially 

 Muscid flies. This fly has been seen capturing Musca domestica, L., 

 Callijjhora erythrocephala, Mg., Stomoxgs calcitrans, L., Fannia 

 canic'idaris, L., PoUenia rudis, F., OrtheUia cornicina, F., Bibio longipes, 

 Lw. ; while a female S. merdaria was seen to take Scatops notata, L. 

 The preference of Scatophaga for Muscid flies is noticeable.
