Tabanus (Therioplectes) wyvillei, 9 , n. sp. 



Type female and two others from Xarkanda, Himalayas, 9,000 

 ft., July 1907 (Lt.-Col. F. Wyville Thomson, I.M.vS.) ; and' another 

 female from Kasauli, India, from the same donor, who sa^-s of 

 those from Narkanda, " \'ery common in the Himala3^as ; annoys 

 man and animals by 1)iting." He also notes the eyes are red with 

 three transverse green bars. 



A smaller species than Therioplectes /i/r///,s-,\\'alker, distinguished 

 from it b}' the slender palpi, and bj' the golden yellow pubescence 

 on abdomen, which in well-preserved specimens almost wholly covers 

 it, whereas in the Walker species the same coloured pubescence 

 is chiefly confined to the segmentations ; the sides are very much 

 less reddish yellow, only appearing so on the sides of the second 

 segment. The tibiae are much lighter reddish yello\\ . Length of 

 type 13 mm., others from 13-14 mm.
