Barkuda, many examples, 4-19 x* 19 (Annandale and Gravely) ; 

 I2 , viii'i9 (Annandale, "caught in jungle"); 6 - ixi9 (Annandale, 

 " flew into verandah on wet and stormy evening and after rust- 

 ling round lamp, settled on white wall "). 



This is one of the commonest dragonflies on Barkuda through- 

 out the hot season and wet weather, disappearing almost entirely 

 by the end of October. , 



In its season it hovers in clouds over the island at a consi- 

 derable height, but in September it flies lower. It probably does 

 not breed on the island to any great extent, but females have 

 occasionally been observed ovipositing in the pond. Dr. Annan- 

 dale has noticed that it hangs on to the twigs of trees and bushes 

 at night, as a rule in considerable numbers on a single bush or 

 tree. The body hangs vertically downwards ; the first two pairs 

 of legs are bent Upwards close to the head and clasp the twig, 

 while the hind pairs are stretched downwards and backwards be- 

 fore they do so. Pantala flavescens was once observed hawking a 

 small butterfly.
