Described from four c5' cJ in the Indian Museum : Mergui, 

 Tenasserim (Doherty) ; Pyinmana, Burma, vi, 1910 (7/. L. 

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

 1500 ft., vii. 1917 (Keht/>). 



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

 splendour. Tiie Indian Museum specimens from Tenasserim 

 were named by Bigot as his ma;/nijifus, but I now feel sure they 

 are synonymous with Walker's fjemmifer, and possibly pidjcscens, 

 AVulp, may be another synonym.
