Female Head .—Entirely clad with broad spatulate scales which in front 
for about half the total distance from vertex to occipital foreman are a deep 
rich blue while on the hinder part the colour is dark blue-black; in a fresh 
specimen the blue colour is very marked but after death in some specimens 
this colour fades assuming a bluish-white shade though even here in certain 
lights the deeper shade can be obtained, d he posterior margin of this blue 
band is straight, running transversely across the head; in some lights the 
central part only of the band shews blue the sides appearing white but a 
shift in the position will bring out the blue at the sides as well. In one 
specimen some of the scales shew bronze and purple tints but the predominant 
colour best seen under a hand lens is the deep blue. The scales behind 
this band are purple-black or purple-bronze in some lights. On the nape 
are two or three rows of very broad topped upright forked scales; vertical 
and orbital bristles brown. Basal joint of antenna dark brown and nude, 
remaining joints dusky, with numerous silky-white downy hairs and long 
black verticillate hairs. These hairs are longer than is usual in a female. 
Clypeus dark brown and nude. P alpi about one-ninth of the proboscis (?) five- 
jointed. There appear to be three very short basal joints followed by two 
joints of about equal length or it may be only one joint; the terminal joints, 
are thickly clad with dark purple-brown scales. Proboscis of great length 
as long, or longer than the whole body, slender and clad with purple- 
brown scales. v 
Thorax.— Prothoracic lobes light yellowish-brown, clad with broad 
black spatulate scales with truncated ends and a row of black bristles. 
Mesonotum shiny yellowish-brown, almost orange towards the centre but 
ochraceous over the shoulders, thinly clad with black hair-like scales, and a 
. patch of about three or four broad spatulate scales on either side of the 
bare space in front of the scutellum ; bristles light brown. Scutellum light 
yellowish-brown with black scales which are as broad as long and have 
square ends ; scutellar bristles light brown two on the central lobe but there 
are scars which shew some have been removed. Four is probably the normal 
number. Pleura with a large dark brown central patch surrounded by 
ochraceous margins. Running vertically down the centre of the dark area 
(which occupies two-thirds of the total area of the pleura) is a line of broad 
spatulate pearly-white scales, this pleural patch and its band of scales is 
very conspicuous by reason of the light coloured parts bordering it. Wings 
smoky clad with dark sepia-brown scales. All the veins have a double row 
of rather long narrow median scales and all have lateral scales even the 
sixth which are linear except on the fork cells where they are larger and 
cla\ate , first fork cell a trifle longer and narrower than second, its base 
nearer the wing apex, its stem about as long as the cell; posterior cross 
vein shorter than median and distant about twice its own length from that 
vein. Coxae pale ochraceous with pale bristles and elliptical pearly-white 
scales; femora clad with dark purple-brown scales; on the fore femora is a 
thm line of golden scales running down the basal half of the anterior surface 
and on the apical half are two oval patches of pearly bluish-white scales one 
about the junction of middle and apical thirds, the other a short distance 
from the apex; the mid and hind femora shew similar patches but the mid 
has also a narrow line of white scales on the basal half of the anterior surface 
and both it and the hind femora are clad with ochraceous scales on the
