Aioretomyia Ostentatio. 
Of medium size with a conspicuous bright golden band down the 
centre of the mesonotum, a golden line running round the anterior margin 
I of the mesonotum which bends in on each side just in front of the wings, 
and a spot of bright golden scales over the base of each wing, three spots 
on the scutellum, and a central golden line on the head; rest of the meso¬ 
notum with rich dark brown scales. Wings heavily scaled with rather 
broad clavate scales. Palpi proboscis and legs dark brown scaled. 
Abdomen with large pearly-white lateral spots. 
Female Head .—Dark brown ; in the centre a line of bright golden 
narrow-curved scales broader behind than in front, bright golden narrow- 
curved scales along the orbital margins, and on either side of the central 
line there is a triangular patch of rich purple-brown broad flat scales with 
: rounded ends set row behind row in an imbricate manner; outside this 
patch is a small spot of golden flat scales succeeded by purple-brown scales, 
and behind on the occiput are a few rows of golden-brown upright forked 
scales; vertical bristles bright golden, about five in number, at their base 
the golden narrow-curved scales are massed and form a distinct spot; 
■orbital bristles short, about three a side and dark brown. Basal joint of 
antenna light yellowish-brown with a few pale hairs and small golden 
scales on the inner face, second joint longer than third with a few small 
scales and numerous dark brown hairs, no regular verticillate hairs, 
remaining joints dusky-brown with pale tomentum and dark brown verticils. 
Facies pale yellow. Clypeus dark brown, frosted, and nude. Palpi very 
short about one-seventh length of the proboscis clad with dark purple- 
brown scales, with certainly three possibly four joints. Proboscis clad 
[ with dark scales, not more than two-thirds the length of the abdomen. 
Thorax .—Prothoracic lobes very dark brown clad with small flat scales 
with ends slightly rounded, purple-brown in colour, and a row of dark 
brown bristles. Mesonotum deep brown clad with narrow-curved scales 
as follows: a line of bright golden scales runs round the margin of about 
the anterior half and ends posteriorly by bending in almost at right angles 
nearly to the central line, down the centre as far back as the bare space in 
.front of the scutellum is a narrow band of bright golden scales about six 
scales broad, and above the base of each wing is a short line of golden 
scales, the rest of the mesonotum being densely clad with dark purple- 
[■ibrown scales (dark bronze under a hand lens). There are the usual lines 
I of bristles and they are dark purple-brown in colour. Scutellum dark 
blackish-brown clad with narrow-curved scales only, of a bright golden 
colour, those on the central lobe being longer than those on the lateral 
lobes. The scales are arranged in three patches with bare space between. 
Bristles dark purple-brown, central lobe bristles knocked off but the scars 
shew the number to be four. Pleurae dark brown with patches of racquet¬ 
shaped pearly-white flat scales. Wings brown with dark brown scales, 
double row of elongated spatulate median scales on all the veins but larger 
on the anterior veins than the posterior. The wing is very densely scaled 
and the lateral scales are clavate. The second long vein commences a good 
deal nearer the wing base than is usual; fork cells long, first fork cell about 
one-third the length of the wing, about twice as long as its stem, and about 
one-and-half times as long as the second, of about the same breadth as
