Described from a few of each sex in the Indian Museum: 

 Darjiliog, 8-11. viii. 1909, including type 6 (J. T. Jenkins), and 

 type $ , 8. viii. 1909 (Paiva) ; Dharampur, Simla, 5000 ft., iv.-v. 

 1908 ; Simla, 7000 ft., 11. v. 1908 (both Annandale). 



If Platypalpus can be regarded as distinct from Tachydromia, 

 which seems doubtful, the three species of mine — orientalis.gentilis, 

 and ferrngineus — will belong to it, as described ; but my P.pallidi- 

 tibice and P. incisa belong to Tachypeza, the anal cross-vein being 

 distinctly present in the former and a part of it in the latter.
