silvery tomentum below, these scales are very difficult to see in the dried 
specimen as they lose their metallic lustre and take on the colour of theii 
background. Remaining joints black, the second having black scales 
inserted all round its basal half; verticillate hairs dark purple. Palpi more 
than one-fourth, less than one-third the length of the proboscis with three 
evident joints, but on removing the scales the palpi are seen to consist o: 
five joints. The scales are for the most part coppery-purple, though ir 
some lights a patch of peacock-blue scales is to be seen on the upper surface 
of the apex of the second joint. Proboscis rich coppery-purple but this 
may change to deep bronze-green or dark peacock-blue with a change ir 
the direction of the light. In fact the change of colour produced by change 
of position is beyond description. 
7 kovax .—Looked at from above under a hand lens the prothoracic 
lobes are bright peacock-blue, but seen sideways the scales are of mixec 
colours, silvery apple-green and peacock-blue the predominant colours being 
bright peacock-blue. Mesonotum in a good light under a hand lens seer 
from above is dark bronze-green over the greater part of its surface shading 
at the margins into beautiful golden and apple-greens with bright peacock 
blue patches over the wing roots and on the front margin just over tht 
neck, the scales on the shoulders behind the prothoracic lobes are silvery 
the scutellum in most lights is clad with apple-green scales with some 
peacock-blue intermingled. Pleurae dark purple-brown, clad with metallic 
silvery scales. Wings brown, with marked iridescence clad with rich coppery 
purple scales, median cross vein very short about three times its own length 
from the supernumerary and nearer the base of the wing, posterior cros‘ 
vein with a double curve commencing to the side of the median cross veir 
nearer the wing apex, in length about twice that of the median. Coxa 
dark brown clad with silvery scales; fore femora clad above, at the sides 
and on the apical half of the ventral surface with rich purple and coppery 
scales, on the basal half of ventral surface with pale golden scales, miq 
femora similarly scaled above and at the sides, but clad with pale golderl 
scales on the whole of the ventral surface, hind femora with golden scales! 
beneath, and laterally on the basal half, elsewhere purple scaled ; knee 
spots of all legs pale rose-red or white; tibia and tarsus of fore leg coppery 
purple or deep royal-purple in some lights ; the other legs are similarly 
scaled, but show white bands as follows : at the base of the metatarsus anc 
hrst tarsal joint of the mid leg and at the base of the first tarsal joint or 
the hind leg. 
Abdomen .—Dorsally clad with scales which appear rich royal-purple or 
coppery-purple according to the direction of the light and with creamy-yellow 
basal lateral spots. I he venter shews a purple band in the centre anc 
creamy-yellow bands on either side of this. When the abdomen shrinld 
in drying the lateral spots may disappear or appear as part of the yellow 
banding on the venter, but in the fresh specimen they are very conspicuous 
Male .—The male plumes are dark steel-grey. The palpi are coppery 
purple with paler scales at the apices of the second and third joints. The 
bands on the legs are practically absent only the merest trace appearing or 
the under surface of the base of the first tarsal joint of the mid and also o; 
the hind leg.
