inetaootum rather greenish grey in male, pale yellowish grey in 

 female. Abdomen of male brown, with an indistinct row of 

 blackish dorsal spots. In the female the first segment distinctly 

 pale yellowish grey, the remainder rather bright yellowish, and 

 blackish towards the sides ; dorsum blackish towards the tip. 

 Belly yellowish, blackish towards the tip. Greuitalia of male 

 reddish yellow or brownish yellow ; consisting of a wide squarish 

 curved dorsal plate, with a longitudinal groove in the middle on 

 the upperside, giving it the appearance of two plates joined 

 together, terminating in the middle of the hind margin in two 

 small black palp-like points, on each side of which, on the margin, 

 are some sparse vei'y short yellow hairs ; the basal joint of the 

 claspers very large, approximately triangular from a lateral point 

 of view, reddish yellow ; the second joint elongate, narrowly 

 conical, moderately curved upwards ; an inner pair of small organs 

 with clubbed tips ; the large basal segments of the claspers joined 

 below, almost forming a ventral plate. Ovipositor reddish 

 mahogany-brown. Leas brownish yellow, tips of femora and 

 tibiae blackish, tarsi blackish. Wings: ground-colour very pale 

 grey, nearly clear ; a little darker grey colour filling the costal cell 

 and extending in three irregular moderately broad bands across 

 the wing the first beginning just beyond the humeral cross-vein, 

 the second crossing the middle of the basal cell, the third beginning 

 over the base of the 2nd longitudinal vein ; the first two bands 

 end in darker grey elongate spots in the anal cell, the third is hardly 

 separable from the slightly darker grey tinge that fills the inner 

 and major portions of most of the cells in the wing. The basal 

 cell has a darker brownish streak towards its tip just above the 

 5th vein ; the stigma is brown, the region below it a little darker 

 grey ; the discal cell, the fork of the upper branch of the 4th 

 ongitudinal vein, and the tip of the 3rd are all very narrowly 

 infuscated ; and also to a slight degree the tips of all the endings 

 of the 4th vein. Pedicle of 2nd posterior cell about half the 

 length of the discal cell, which is large. A distinct specific 

 character is that there is a practically clear spot in the 2nd, 3rd, 

 4th, and 5th posterior cells, situated on the hind margin of the 

 wing ; the hind margin beyond the 5th posterior cell is also more 

 or less clear. Halteres yellowish brown. 



Lenf/th: tf 16 millim. ; $ 24 millim. (including nasus and 

 ovipositor). 



Described from a single specimen of each sex received from the 

 Lucknow Museum, taken at Naini Tal, 6400 ft., Kumaon, 

 Western Himalayas, in May or June 1893. 



Types in the Indian Museum. 



Very near T. Tiimalayensis, but easily distinguished by the 

 absence of the pronounced subapical yellow ring on all the femora, 

 and by the presence of the pale marginal spots in the 2nd, 3rd, 

 4th, and 5th posterior cells.
