ATRICIIOPS. 119 



minutely pubescent ; apical half of all femora and the whole of 

 the middle tibiae reddish tawny : some whitish-grey hairs below 

 femora ; hind tibiae shortly pubescent, with reddish-bronze reflec- 

 tions. Wings pale grey, apical half pale brownish; no distinct 

 stigma, but a rather broad ill-defined brown band runs from the 

 stigmatic portion of the costa towards the posterior border, but 

 fades away before reaching it ; discal cell three times as long as 

 broad ; anal cell closed just before the border ; by a strong con- 

 vergence of the veins the fourth posterior cell (termin, O.-S.) is. 

 almost closed, thus (if a stable specific character) separating this 

 species from all other Oriental species in this genus ; halteres 

 yellowish, knobs black, rather large ; tegulae cinereous grey. 



Length, 10 mm. 



Described from one from Margherita and two $ $ from 

 the base of the Dawna Hills, Amherst District, Lower Burma, 

 1. iii. 1908, all in the Indian Museum (Annandale) ; Bojiaghat, 

 12. vi. 1915 ; Ivathgodam, 16. vi. 1915.

 fig. 3 (1912). 



$ . Head blackish, mainly dusted with bluish grey; frons, from 

 the ocelli downwards for three-fourths of the distance to the 

 antennae, shining black, bare, in which colour is inset a deep dull 

 velvet-black triangle, its base on the lower margin of the shining 

 part : antennae black, dusted with bluish grey, 3rd joint dull 

 reddish yellow : mouth-parts dusted with bluish grey. Thorax 

 blackish, with a shining bluish-grey reflection ; two not very obvious 

 whitish dorsal stripes, and there are greyish reflections on the 

 shoulders, posterior corners, and elsewhere, viewed in certain lights; 

 a few soft black hairs on dorsum ; sides, pleura?, and scutelium 

 concolorous, a little yellowish behind the thoracic stigma. Abdomen 

 blackish, barely shining, with short sparse greyish pubescence; 

 1st segment dusted with bluish grey, 5th and 6th with light 

 bluish-grey hind margins; venter mainly blackish. Legs black, 

 minutely pubescent, coxae dusted with bluish grey. Wings very 

 pule rey; across the centre a reversed triangular brown spot 

 reaching from the costa to the hind margin, where its apex meets 

 the tip of the closed anal cell, the colour filling most of the discal 

 cell and crossing the tip of the upper basal cell ; following the 

 discal margin of this brown triangle (at a distance leaving a 

 moderately wide intermediate clear band) is the proximal margin 

 of a second large brown band, which fills thence the whole of the 

 discal part of the wing ; a brown streak in the middle of each 

 basal cell; stigma dark brown, filling distal half of cell; halteres 

 yellow, clubs black. 



Length, 6 mm. 



Described from a perfect $ in the Indian Museum from 

 Kurseong, 5000 ft., 6. ix. 1909 (Annandale).
