on all the joints after the second. Last joints not elongated. Palpi rathe 
short, black scaled ; joints concealed. Proboscis long and slender blacl 
scaled. 
Thorax .—Prothoracic lobes very prominent, black, clad above and ii 
front with narrow-curved scales, behind with broad dusky black scales 
Mesonotum black, densely clad with long narrow-curved black scales; j 
broad line of bluish-white narrow scales runs down the centre for about two 
thirds the length of the mesonotum. In front of each lobe of the scutellun 
there is a bare space. Mesonotal bristles black. Scutellum black, centra 
lobe clad for the most part with broad bluish-white racquet-shaped’ scales- 
at the apex there are two rows of dark scales shewing metallic tints. Or 
either side is a bare space, then a tuft of broad black scales on eithei 
lateral lobe. Scutellar bristles black. There are four central and si> 
lateral. Pleura black or very dark brown with a broad line of white scale* 
crossing it transversely and a patch of white scales above the mid coxa 
\\ ings clad with black scales ; a double row of median scales on all vein* 
to the fourth inclusive, the lateral scales of first fork cell rather broad ; all 
the scales with square ends ; first fork cell about the same length as its 
stem a little longer and narrower than the second, its base nearer win° 
base, supernumerary and median cross veins meeting at an angle, of about 
equal length, posterior cross vein about twice its length from & the median. 
Coxae dark brown ; fore coxae clad with broad white scales in front and 
several bristles on their apices projecting downwards and forwards. There 
is a small patch of white scales on the middle coxa and a band of white 
scales running down the outer side of the hind coxa. Fore legs are entirely 
scaled with purple-black scales except for a thin line on the under surface 
of the femora, mid legs white scaled on the under surface of the femora and 
they have a patch of white scales at the apices, the rest of the le^ is 
black scaled. In the hind legs the femora are entirely white scaled except 
for a short distance above where there is a line of dark scales which 
just before the apex expands on to the sides, the immediate apex is white 
scaled ; the metatarsus and first tarsal joint are basally banded white the 
former broadly so, and there is a small patch of white scales at the base of 
the second tarsal joint. Ungues equal and simple on all the legs. 
Abdomen .—Dorsum purple-black scaled. On the venter at the base of 
the segments there is a broad band of pearly-white scales, and laterally 
there are triangular spots of pearly-white scales. On the penultimate seg¬ 
ments the lateral spots extend dorsally and form more or less complete 
basal bands. 
Male Head .—A bare line down the centre which does not shew in the 
lemale. Scaling as in the female. Last two joints of antenna elongated, 
remaining joints very short; verticillate hairs black. Palpi not more than 
half the length of the proboscis, entirely black scaled, very slender and 
except for a terminal spine almost destitute of hairs. They look five-jointed 
but without dissection it is impossible to tell. Proboscis long. 
Thorax .—In all respects similar to the female. The fork cells of the 
wings are remarkably short, of almost equal length not more than about half 
as long as their stems, there is only a single row of median scales and very
