30 PHILIPPINE DIPTERA, II 



be widely spread in the Orient, like the preceding. It was first 

 described in the genus Mmca; but according to Patton and 

 Cragg, 11 who have redescribed it under the name gurnei, it be- 

 longs to the present genus, notwithstanding the form of the 

 proboscis, which on macroscopic examination seems to be very 

 different from that of the type species. 



164. Stomoxys nigra Macq. 1851. 



Los Banos. This common Ethiopian blood-sucking fly seems 

 to be widely spread in the Oriental Region, being recorded by 

 Summers as one of the commoner species at Kuala Lumpur, 

 Federated Malay States. 



165. Lyperosia exigua de Meij. 1903. 



LUZON, Laguna, Los Banos (Baker) ; Rizal, Alabang (Mitz- 

 main) . A common blood-sucking fly of the Orient. 



166. Mydsea duplicata Meig. 1826. 



Numerous specimens of both sexes from Baguio, Benguet. 

 The only difference from the European specimens, that I can 

 perceive, is that the female is darker and has darker legs and 

 a little broader frons. The present species is not to be con- 

 founded with M. duplex Stein from New Guinea, which has only 

 posterior dorsocentral bristles. 



167. Orchisia costata Meig. 1826. 



Specimens of both sexes from Mount Maquiling, Laguna, and 

 from Baguio, Benguet. This species is rare in central Europe, 

 more common in southern Europe, and was described as Ccenosia 

 marginata by Wiedemann from southern China. It was not 

 without emotion that I found in Professor Baker's collection 

 specimens of this pretty fly, identical with those which I find 

 here in the alpine valley of Susa, near Turin, on swampy places, 

 over Mentha and other aromatic herbage. 



It is interesting to note that at Baguio, Benguet, are to be 

 found three European flies: namely, Melanostoma mellinum 

 (orientate), Mydzea duplicata, and Orchisia costata. 



168. Amphicyphus reticulatus Dol. 1856. 



Mount Maquiling. Identical with specimens from Calcutta, 

 India, in my collection; described from Borneo as an Ensima, 

 and subsequently recorded from Java.
