Baccha nigricosta, Brunetti, Rec. Ind. Mas. ii, p. 50 (1908) ; i, pi. xi, 

 fig. 5, wing (1907).

 and shining black ; below antennae a wide shining black stripe ; 

 frontal triangle above antenuse shining black seen from the front. 

 Antennae reddish-brown, the two basal joints black. Proboscis 

 black, tip red. Thorax shining black, minutely pubescent, un- 

 marked, sides blackish-grey; scutelhim rather large, shining black,

small transverse spots at middle of sides of 3rd segment, and a

Described from one 6 taken by Dr. Annandale (19-22. ix. 1906) 

 at Bhim Tal, Ivumaon ; in the Indian Museum collection. A second 

 specimen from Pusa, 16, xii. 1915.

 spicuous blackish cloud in the middle of the wing differentiating 

 it from all the clear-winged species except umhrosa, and sdso 

 sufHcieutly from the two species classed by me as wholly brown- 

 winced.
