Tenasserim fThagatà) April 1887. Garin Gheba, May 1888. 



The two specimens contained in this collection only differ in 

 the width of the fiavous band which, in the specimen from 

 Tenasserim occupies nearly the entire disc. A. costata differs 

 from any of its congeners known to me by the costate elitra.
