Green, pale ochraceous, or green and dark ochraceous ; abdomen above with some small lateral black 

 spots which are most distinct in the paler coloured specimens. 



Tegmina and wings pale hyaline, the venation and the costal membrane of tegmina pale brownish 



or ochraceous. 



Rostrum just passing the intermediate coxeb ; opercula about reaching the penultimate segment of 

 the abdomen, concavely sinuate on each side near base and then convexly ampliated, especially on inner 

 margins, their apices narrowed and obtusely rounded.

This appears to be the commonest and most widely-spread species of the Eastern 

 Cicadida', scarcely any collection of these insects made in the above localities is without it, and 

 I found it a somewhat abundant species in the Malay Peninsula when collecting there some 

 years ago. It is variable in hue, but is easily recognised, especially by the length and shape 

 of the opercula.
