1. Chironomus, sp. 

 Two species. 



[In streams in the Hari-rud valley, as at Daua-sanjiti and at Kilki, the water was 

 full of the larva of some insect ; it occurred as a very minute scarlet point, as if just a 

 speck of blood, and gradually grew to good dimensions. These did not look weU in a 

 tumbler of water : w^e did our best to clear the water, but in vain ; however they proved 

 to have been harmless. They were most common where sheep had been watered in any 

 numbers. — J. E. T. A.] 



Tabanid^e. 



2. Tabanus tropicus, Linn. Syst. Nat. ii. p. 1001. 



Sab. Helmand valley. 

 A European species. 



[Our horses were pretty severely bitten by this species at Padda-sultan on the 

 Helmand ; this fly and the large Asilus are well known to the natives, and called " Sone." 

 These frequently cause a stampede amongst cattle, they say. — J. E. T. A.]
