Described from several specimens in the Indian Museum :

 Almora. Kumaon, 5500 ft., 10-21. ix. 1911 {Paiva)-^ Shillong, 

 4900 ft., l.vi. 1918 (i^(«o) ; Katmandu, Nepal. It occurs also in

Diftering from iSargas mainly in the densely pubescent eyes, 

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

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

 sized facets in the 5 ; '^I'cl antennal joint longer than in Sargvs ; 

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

 moi'e indistinct.

Life-hisiory. Tlie common C. formosa, Scop., of Europe, has 

 been bred from garden-mould and from Brassica rufa. 



Some confusion has arisen over the generic names Cldoromyia 

 and Clwysomyia (under wiiich formosa \\as knoA\n in Euro]:>e for 

 many years), which is concisely cleared up by A'errall (Brit. Elies, 

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

 generic type in 1910, ]n"esumably unaware of Verrall's priority.
