SOME PHILIPPINE SPECIES OF THE GENUS MUSCA 



LINNAEUS 



Lecturer on Entomology and Parasitology, Edinburgh University 



In August, 1922, during my visit to Prof. M. Bezzi at Turin, 

 he very generously gave me a large collection of species of 

 Musca from the Philippine Islands to describe. The specimens, 

 151 in number, were collected by Prof. C. F. Baker, in the 

 vicinity of Los Bafios, Laguna Province, in Baguio, Benguet 

 Subprovince, Luzon, and in two localities in Mindanao ; by Mr. 

 R. C. McGregor in Panay and Batbatan Islands ; and by Mr. M. 

 B. Mitzmain in Alabang, Rizal Province, Luzon. The specimens 

 collected by the latter are of peculiar interest, as some of them 

 are the hamiatophagous species referred to in his well-known 

 investigations into the method of transmission of the trypano- 

 some of surra in the Philippine Islands. I believe they were 

 caught on animals in association with biting flies such as 

 Stomoxys calcitrans. Bezzi x has already recorded two species 

 of Musca, M. crassirostris Stein and M. inferior Stein, from 

 these Islands. In addition, M. conducens Walker, M. nivei- 

 squama Thomson, M. bivittata Thomson, and M. favillacea 

 Walker have also been recorded from the Philippines. As these 

 Islands form a part of the Oriental Region, it is only natural 

 to expect that the species of this genus, as Professor Bezzi has 

 pointed out in the case of other dipterous genera, would be to a 

 large extent identical with those from other parts of the
