black ; gradually widening from the base to the 6th segment, 

 which is the widest, thence sharply narrowing. Ovipositor some- 

 what robust, dark brown, practically bare, the long terminal 

 points shining red-brown. Legs wholly very dark mahogany 

 brown, nearly black. Wings brown on anterior half, the colour 

 gradually fading away posteriorly to the grey hind margin ; a 

 small, roughly crescent-shaped, hyaline spot across the 1st basal 

 cell, entering the cell above and below, and situated close to the 

 origin of the 3rd vein. .Four posterior cells ; discal cell 5-sided, 

 the veinlets from its outer upper side almost parallel ; anterior 

 cross-vein opposite fork of 2nd vein ; posterior cross- vein at lower 

 corner of discal cell; upper branch of 2nd longitudinal vein 

 forking just before its middle. Halteres black. 



Length 20 millim. 



Described from a type male in the Vienna Museum from Central 

 Tonkin and a single female (type) in the Pusa collection, taken in 

 April 1905 in the Khasi Hills, Assam, at 1000 to 3000 feet 

 altitude.

" $ . "Wings brownish, with two broad hyaline bluish-opalescent 

 cross-bands ; thorax red ; abdomen velvet-black with grey cross- 

 bands. Length 9-10 mm. (without ovipositor). 



" Head and 1st joint of antennae ferruginous red ; the rest 

 of the antennas brown. Thorax ferruginous red with a faint 

 darker stripe in the middle ; scutellum and metathorax blackish. 

 Halteres black. Abdomen velvet-black ; each segment, beginning 

 with the 2nd, with a bluish grey plumbeous cross-band at the 

 base ; the last segment ferruginous red ; ovipositor reddish brown. 

 Legs (only the right hind leg is left) brownish red : tibiae and 

 tarsi darker. Wings pale brownish at the extreme base ; a broad 

 brown cross-band in the middle ; it occupies, on the anterior 

 margin, the interval between the origin of the 2nd vein and the 

 tip of the auxiliary ; on the posterior, between the tips of the 

 6th and 7th veins ; the last quarter of the wing is pale brown. 

 The two hyaline spaces (or cross-bands) thus remaining between 

 the brown portions of the wing have a beautiful bluish opalescence; 

 four posterior cells. 



" Hub. Ceylon (Pundel Oya Valley, 3800-3900 ft. alt,, 26. xi. 

 to 27. xii. 1859, Mr. Alois Humbert, from Geneva). 



"A single female in the Museum at Geneva. 



" The tip of the auxiliary vein a little anterior to the proximal 

 end of the 2nd submarginal cell ; the 1st submarginal cell and the 

 1st posterior cell are of equal length ; the great cross-vein at the 

 very base of the discal cell." (Osten Sacken.} 



This must be a very striking species, but I have not seen it.
