parti -coloured scales, the white scales forming more or less basal 
bands, and a white median spot to each segment, especially 
posteriorly ; each segment has also an apical border of pale hairs ; 
first segment nude, with only a patch of white scales in the middle, 
and numerous fine pale hairs ; the white scales at the bases of 
the abdominal segments spread out laterally and form distinct 
lateral spots ; on the venter the abdomen is broadly, basally 
banded with white scales, the parti-ccloured ones forming only 
narrow apical borders. Legs thickly clothed with ochraceous, 
parti-coloured, and white scales, which stand up from the surface 
more than usual, all the joints banded ; fore femora not very 
distinctly banded ; tibiae with three white bands, metatarsus 
with two, the first two tarsal joints with basal white bands, last 
two unhanded ; in the mid legs the femora are white at the apex, 
and have one distinct white band and two white patches below, 
not forming bands ; tibia? and tarsi as in the fore legs ; in the 
hind legs the tarsi are all basally white. Ungues thick, short, 
uniserrated ; the ungues, which are equal on all the legs, have 
spines on their sides. Wings with the veins densely covered 
with large parti-coloured and yellow and white scales, the fringe 
alternately black and white ; the majority of the scales are half 
purple and half yellowish-brown, but on the costa and first longitu- 
dinal, just over the base of the fork-cell, the scale's are plain 
yellowish- white, forming a distinct spot ; there are also white 
scales forming spots at the base of the fork-cells, on their stems, 
a dusky spot over the cross-veins and at the base of the second 
long vein, where it joins the first ; posterior cross- vein a short 
distance in front of the mid cross- vein and much longer ; first sub- 
marginal cell longer and narrower than the second posterior cell, 
their bases about level and their stems, which are white scaled, 
shorter than the cells and nearly equal in length. The surface 
covered with very minute bristles. Halteres ochraceous.
