1. Hemicordulia asiatica, Seiys. 
Up to the year 1918 this rare dragonfly was only known Irom 2 males both of 
which had been taken in Assam. In the year mentioned whilst going over a 
collection of specimens sent from the Agriculture Institute, Pusa, I found a pair 
of these insects which had been taken some time before by Mr. Bainbrigge 
Fletcher at Sliillong and had remained in the Pusa collection for some time 
unidentified. 
i\Ir. Fletcher on his next visit to Shillong took a number of specimens both 
male and female on the Ward Lake and has sent me others since. 
It was thought that the insect was localised to the N. W. until this year when 
I received a letter from Mr. Bainbrigge Fletcher who was staying in Kodaikanal 
stating that he had seen a Corduline on the lake there which much resembled 
Heinicorduiia asiatica., He finally secured specimens both by the net and others 
which he found caught up in spider webs on sedges, on the borders of the lake 
and on receipt I found them to be true H. asiatica. 
ilr. Bainbrigge Fletcher in his covering letter, wdien sending these specimens 
suggested that the insect would probably be found in the Nilgiris and in this he 
proved to be a true prophet. Two days after receiving his letter I had occasion 
to go down to Coonoor and there in a shady lane adjoining Sims Park took my 
first H. asiatica, a male, which was hawking insects up and down the road. 
The same day on returning to Ooty I ran doun to the lake and immediately 
saw a male and shortly afterwards several more, hawking along the banks. 
The insect is fairly common on the Lovedale lake as well as the Ooty lake 
from August to the 1st November, exuvia being common in September and larvse 
not difficult to obtain amongst the grass and sedges lining both lakes. 
1 hope to obtain information of this insect from the lake in Newara-Eliya, 
Ceylon, next season and probably also from the lake at Mahableshwar. From 
the numbers seen it would appear that the insect is more common in the south 
than the far north.
