THE DIPTEROUS INSECTS OF B A R K U D A 



ISLAND. 



Bv Cedric Dover, Assistant. Zoological Survey of India. 



The present note can only be said to illustrate the general 

 character of the dipterous fauna of Barkuda as it has been found 

 impossible to name all the species collected ; and it is for this 

 reason that I have arranged this paper in the form of notes under 

 each family. We have to thank Mr. Bnmetti for naming some 

 specimens and for confirming the identifications of the others. 

 Mr. Edwards has identified the Culicidae. In the arrangement 

 I have followed Sedgwick's " Zoology." 



Family Cui,icid.4lE. 



Anopheles subpictiis Grassi and Stes,omyia albopicia Skuse are 

 the commonest mosquitoes on the island. A. ? culicifacies Giles, 

 Culex concolor R. D., and Ciilex? si'^/ews Wied., have also been 

 taken. Stegoniyia iv-alba Theo. is not uncommon. 



Family Chironomidae. 



Culicoides pcregrinus Kieff. occurs in vast numbers at the 

 end of the rainy season, swarming with other forms round lamps 

 in the verandah of the bungalow. Calyplopogon albitarsis Kieff. 

 has also been taken. 



Family Psychodidak. 



A small species of Phlebotomus occurs, but is rather scarce. 



Family Tipulidae. 



The only Tipulid taken on the island is the widely distribut- 

 ed Conosia irrorata Wied., which is fairly common.' 



Family Bibionidae. 



Plecia tergorata Rond. is often abundant during the rains. It 

 has been seen hovering in the air about six to ten feet from the 

 ground in considerable numbers on dull showery mornings. 



Family Stratiomyidae. 



The only members of this family taken on Barkuda were a 

 single specimen of Odontomyia minuta Fabr. (io-iv-20, Annan- 

 dale) , and of a new genus of Pachygastrinae.
