Barkuda, many examples, -zo'viii'ig (Dover) ; 3rviii*i9 (An- 

 nandale, "fluttering over jungle"); 6'ix'i9 (Annandale, "caught 

 in jungle ") ; 27'ix-i9 (Annandale) ; 8iv2o (Annandale and Dover). 



A fairly common species at all seasons. The females are 

 usually more abundant than the males. It is generally found 

 flying low in a fluttering manner over jungle and often settles on 

 the ground or on low herbage. 



It bears a distinct superficial resemblance to an ant-lion.

 pond at dusk "). 



A moderately common species generally found flying round 

 the pond on Barkuda, but stray specimens have also been observed 

 in the day. Only four examples were captured because this 

 dragonfly is a difficult one to catch.
