blue flat scales, another exists in the middle line just before the 
bare space in front of the scutellum ; there are also two rows of 
brown bristles; prothoracic lobes covered with flat bright blue 
scales; scutellum with a patch of flat blue scales to the middle 
lobe; narrow bronzy ones to the lateral lobes; four bristles on 
the median lobe and four on each of the lateral lobes like 
U. pulcherrima ; pleurae pale bright testaceous, with one large 
patch of pale blue flat scales and traces of a second smaller one, 
and with scattered brown bristles ; metanotum pale yellowish- 
brown. 
Abdomen steely-black, covered with dusky-black scales, the 
third to eighth segments with a median apical white triangular 
spot, the base of the triangle level with the posterior border of 
the segments, these spots show pale blue and pearly reflections in 
some lights, the posterior borders with small pale hairs ; there 
are also pearly apical lateral spots; venter pale scaled. 
Legs with the coxae very pale ochraceous, with a few dark 
brown and pale golden bristles ; bases and venter along the 
basal half of the femora pale ochraceous, apical half dark brown, 
with a pure white apical dorsal spot; fore tibiae, metatarsi and 
tarsi dark brown, the apex of the tibiae and metatarsi with a 
small white band, traces of the same on the apices of the first 
three tarsi; mid legs similar in colour to the fore legs, but the 
femora much enlarged, hind legs with the tibiae with a large 
white apical patch, metatarsi and first tarsal joint with a small 
white apical band, the second tarsal with a broad white apical 
band, the last two joints being pure white; ungues equal, thin 
and simple. 
Wings with dark- and pale-brown scales, those on the veins 
spatulate, short and rather broad, single rowed, the lateral ones, 
where they occur, pale, lanceolate and large ; the costal border 
dark, with fine pointed narrow lanceolate scales along its free 
border ; scales on the first, second, third, fifth and sixth 
longitudinals dark brown, those on the fourth pale brown, except 
at the fork, the root of the fifth is densely scaled with blue 
scales, with pale mauve reflections, forming a distinct blue line ; 
on the fork-cells and on all the third vein are large lateral pale 
lanceolate scales ; there is a very distinct incrassation forming a 
quasi-seventh vein ; first sub-marginal cell much smaller than the 
second posterior cell, lying close to the first longitudinal vein, 
but its stem not so near as in the former species (pulcherrima); 
the stem three times as long as the cell; the junction of the
