a little but quite distinctly more proximad. The streak continues 
through the 4th posterior cell before the middle of the latter, and 
ends broadly in a widened state at the 5th longitudinal vein a little 
before the margin of the wing. The 4th streak begins on the 
costa, immediately beyond the stigma, crosses the Ist submarginal 
and Ist posterior cells about their centres, crosses the 2nd poste- 
rior cell before the middle, and the 3rd at its middle, where it 
becomes bifid ; a small single elongate spot in the 4th posterior cell 
marking its termination. The 5th streak, which is rather narrower 
than the others, runs from the lower branch of the 2nd longitu- 
dinal vein, near the tip of the wing, to the upper branch of the 
4th longitudinal, also near its tip, crossing the 2nd submarginal 
cell just before its middle. The 6th streak very short and sub- 
apical, from immediately before the tip of the Ist submarginal 
cell to about half way down the 2nd submarginal. Between the 
4th and 5th and the 5th and 6th streaks is asmalJ whitish elongate 
spot near the wing margin. MHalteres black (apparently dis- 
coloured). 
Described from a single ~ in the Indian Museum from Dehra 
Dun (foot of Mussoorie Hills) taken 17-1-10, and presented by 
Dre-eA” Deinms: 
N.B.—Easily known from all other oriental species in the 
genus by the six whitish narrow streaks on the wings in place of 
the usual rosettes. 
It falls in Miss Ricardo’s Division IT.

Head.—Frons nearly + width of head, shining black, bare; 
3 small yellow ocelli at vertex; eyes blackish, bare. Proboscis 
bright yellow, palpi of similar colour, very small. A whitish 
triangular spot on each side between the eyes and the base of the 
antennae. Antennal Ist and 2nd joints black, 2nd with a circlet 
of black and yellow bristles around its tip; flagellar Ist joint 
much wider than the rest, which are blackish brown, the comb- 
like prolongations on the under side, bright yellow. (The antennae 
being incomplete, the exact number of joints cannot be given). 
Thorax and scutellum, wholly shining black, practically bare, 
humeri conspicuous, bright yellow. 
Abdomen black. Dorsum of first three segments mainly yel- 
low, the borders being black, the 4th segment more or less yellow in 
the centre. Belly principally yellow on the first three segments ; 
remainder blackish.
