1921 ] C. Dover • Fauna of Barkuda I. 395 



Family Syrphidae. 



A single specimen of Paragus serratus Fabr. was taken in 

 September, 1919, and several examples (in bad condition) of the 

 genus Chilosia. 



Famil)' Sepsidae. 



Sepsis, the only genus of this family found on Barkuda, 

 inhabits the dung of the Chital (Cervus axis). Only one species, 

 \ixohah\y Sepsis coprophila de. M&\]., is represented in the collec- 

 tion. 



Family Ephydridae. 



Several species, that breed at the edge of the lake and fly to 

 light at night, cannot be identified at present. 



Family Drosophiwdae. 



Drosophila, which lives round bananas and other fruit, is 

 common on Barkuda. Dr. Baini Prashad has succeeded in breed- 

 ing these flies in Calcutta ; they are thought by Mr. Brunetti to 

 be new to science. 



Family Trypetidae. 



Callisloiiiyia pavonina Bezzi, a species which has been taken 

 on the neighbouring islands of the Chilka I^ake and in the Gan- 

 jam District, is apparently the only fruit-fly that occurs on the 

 island. 



Family Ortaudae. 



A few Ortalids have been taken on Barkuda, but it is impos- 

 sible to identify them at present. 



Family Anthomyiidae. 



The Authomyids taken on Barkuda are entirely confined to 

 the shores of the island where they are extremely abundant in 

 damp mud and decaying algae. They sometimes fly to light. 

 They all belong to the genus Lis pa and seem to be four different 

 species, two of which are Lispa i;labya Wied. and L. ? assimilis 

 Wied. The former is represented in the Museum collection from 

 Calcutta, the latter from Jubbulpore, 1,300 feet, and Rangoon. 



Family TachinidaE. 



The identification of the Tachinids is impossible at present 

 Apparently three species have been taken on Barkuda, either on 

 tree-trunks or on termite mounds.
