 Almora, Kumaon, 5500 ft., 10-21. ix. 1911 (Paiva); Shillong, 

 4900 ft., l.vi. 1918 (Rao); Katmandu, Nepal. It occurs also in 

 Ceylon and the Malay Archipelago.

Genotype, Musca formosa, Scop. ; by Verrall's designation 

 (1909). 



Differing from Sargus mainly in the densely pubescent eyes, 

 which are contiguous for a considerable distance in the S , the 

 upper facets larger than the lower ; and wide apart with equal- 

 sized facets in the § ; ^'d antenna! joint longer than in Sargus ; 

 abdomen rather broader also, especially in the $ ; venation rather 

 more indistinct. 



Range. Europe, South Africa, Asia, North America. 



Life-history . The common C. formosa, Scop., of Europe, has 

 been bred from gardeu-mould and from Brassica rufa. 



Some confusion has arisen over the generic names Chloromyia 

 and Chrysomyia (under which formosa was known in Europe for 

 many years), which is concisely cleared up by Verrall (Brit. Elies, 

 v, p. 187). Goquillett claimed designation of the same species as 

 generic type in 1910, presumably unaware of Verrall's priority.
