Hah. Tenasserim ; Tavoy {Boherty, Coll. Dist.). — Malay 

 Peninsula. Borneo. Java. Sumatra. 



Atkinson (supra) records the exp. tegm. in this species as 

 attaining to 66 millim., but I have not seen such large specimens. 



The above description is of a fresh and unrubbed specimen ; 

 the var. saundenii is not found, so far as my experience extends, 

 iu British India, and is to be recognized by the wholly testaceous 

 and not green basal disk of wings.
