numerous dark brown upright forked scales which are inserted as far for¬ 
ward as the orbital margins in the centre ; vertical bristles pale brown, 
orbital dark brown. L>asal joint of antenna dark brown, without scales, 
having a few inconspicuous hairs on the upper part of the inner face, second 
joint pale grey at the base darker at the apex clad with hairs but no scales, 
remaining joints brownish-black clad with numerous short pale hairs; 
verticillate hairs dark brown. Clypeus dark brown and nude. Palpi short, 
with four evident joints which are dark brown, the terminal joint bein^ 
much enlarged and apparently it and the upper surface of penultimate joint 
are the only joints scaled. Labellae light brown. 
Thorax. Prothoracic lobes, light muddy-brown, without scales, with 
a row of dark bristles on the antero-lateral margin. Mesonotum varies 
somewhat in colour, sometimes it is bright reddish-brown in other 
specimens the brown inclines more to a muddy or yellow tint; it is clad 
with narrow-curved scales which under a hand lens appear light bronze but 
under a 2/3 the separate scales are dark brown many of them having 
pale goiden or grey tips, the anterior, alar, and praescutellar bristles are long 
and dark brown. Scutellum in colour and scaling resembles the mesonotum. 
Pleurae pale muddy-yellow, when dry silvery, without scales, but with a 
row of bristles running down the centre in a vertical direction. Wings 
with a brown tint; scales on the costa dark brown almost black the rest 
of the wing scaled with dark brown scales; first long vein with a 
double row of small narrow spatulate median scales for the first two-thirds 
the last third shews in addition on its upper margin a row of scales which 
are at first linear but become clavate the nearer they get to the apex of the 
wing, second long vein clad with a single row of median scales until it 
divides when each branch has also lateral scales on either margin which 
become clavate as they approach the apex; the apices of third and fourth 
ave similar scales, the branches of the fifth have a few linear lateral 
scales, the sixth has only median scales; fork cells short, first longer and 
slightly narrower than second, its base a little nearer the wing base, its 
stem two-thirds the length of the cell; supernumerary and median cross veins 
meeting at a very open angle, posterior cross vein scarcely twice its length 
from median. Coxae silvery-white; fore coxae scaled in front, trochanters 
and under part of thighs silvery; on the hind femora the silvery scaling is 
extended on to the sides and the base; the rest of the leg is clad with dark 
brown scales, with purple reflections. Ungues equal and simple on 
all legs. 
Abdomen. Clad above with scales which generally appear of a dull 
dark brown though they also shew purple tints in some lights. There is 
a paleness at the base of the segments but no true banding. The venter is 
silvery but this is only seen in the freshly killed specimen. 
Male Head .—Scaled as in the female. Basal joint of antenna dark 
brown without scales, the remaining joints except the last two have a dark 
brown ring at the insertion of the verticils, the rest of each joint bein<^ 
semi-translucent with a dusky-brown tint; on the inner face of joints two 
to five inclusive the verticillate hairs are replaced by short bristly hairs; on 
the sixth joint just at the junction of its upper and outer faces there is a tuft 
of yellowish-brown scales generally four in number; these scales are about
