Described from four J 6 in the Indian Museum : Mergui, 

 Tenasserim (Doherty) ; Pyinmana, Burma, vi. 19LU (H. L. 

 Andrewes); Sylhet ; and one 5 from Tura, Garo Hills, Assam, 

 1500 ft., vii. 1917 (Kemp). 



Easily known from all other Indian species by its great size and 

 splendour. The Indian Museum specimens from Tenasserim 

 were named by Bigot as his magnificus, but I now feel sure they 

 are synonymous with Walker's gemmifer, and possibly pubescens, 

 Wulp, may be another synonym.
