Described from one 2 i" the Indiau Museum, Simla, 7000 ft., 

 16. V. 1909 (AnnandaJe). Tliis is undoubtedly a valid species, 

 though it bears a considerable resemblance to himcdmjensis, from 

 which it is easily separated by the clear wings, greater depth of 

 epistome below the eyes, and minor characters. The Uijye (in 

 Bigot's collection), which I have compared, was described from 

 India.
