the back of the occiput. Basal joint of antenna black completely clad with 
flat silvery scales, second and third joints black with a few small scales 
on their inner faces, remaining joints black with numerous short silvery 
hairs and black verticillate hairs. Clypeus black. Palpi about one-sixth 
the length of the proboscis apparently four-jointed clad with black scales 
except on the upper surface of the apical half which is snowy-white. 
Proboscis black scaled not as long as the abdomen. 
Thorax. Prothoracic lobes black, clad with small flat silvery scales 
and numerous long black bristles. Mesonotum black; in the centre is a 
broad band of long silky-white narrow scales running the whole length 
broader in front than behind, and at the base of the scutellum formed 
by broad spatulate scales. Round the margin of all the portion between 
the prothoracic lobe and the wing root of each side is a band of flat white 
scales which over the wing roots are clavate towards the front shorter and 
more spatulate. These scales are distinctly on the mesonotum and though 
below they mingle with the pleural scales they are really inserted on the 
mesonotum and not on the pleurae. The rest of the mesonotum is clad 
with black narrow-curved scales with bronze tints in a good light. The 
scutellum is clad with rather small spatulate scales set in imbricate rows 
and covering nearly the whole surface, they are silvery in the centre black 
at the sides. Pleurae black with large patches of flat silvery scales. 
Wings heavily clad with dark brown scales, median small and narrow with 
square ends, lateral linear with rounded ends; fork cells of about equal 
breadth, first longer than second, its base nearer the wing base, its stem 
about two-thirds the length of the cell; posterior cross-vein rather more 
than twice its own length from median. Coxae black with silvery scales; in 
the fore legs the femora are black scaled above and at the sides, silvery 
beneath, the tibia black, metatarsus black with narrow silvery basal band, and 
joints of the tarsus black ; in the mid legs the femora are black above and- 
at the sides silvery beneath and have a patch of silvery scales above and tc 
the front at the extreme apex, tibia black scaled, metatarsus and first tarsal 
joint with basal silvery band, remainder black; in the hind leg the femur is 
clad with silvery scales except above and laterally on the apical third, the 
tibia is black scaled with silvery spines and the metatarsus black with 
broad silvery basal band; first tarsal joint silvery for the basal half black! 
on the apical, second joint black throughout, last two joints silvery, forel 
and mid ungues equal and uni-serrate. 
Abdomen clad with black scales, all segments after the second with 
narrow basal silvery band and all segments with large square silvery 
lateral spots, venter with basal bands to segments. 
Male ,. With plumose antennae, plumes steel-grey, joints black and 
white except the basal which is black with white scales. Palpi about 
four-fifths the length of the proboscis very slender and without hairs, with 
a broad silvery band about the centre of the antepenultimate joint. Pro¬ 
boscis black. Bases of fork cells nearly level, second broader than the 
first. Legs, abdomen and thorax scaled as in the female. 
Occurrence. Described from several females taken in the jungle five 
miles from Kuala Lumpur and one male and female from the jungle at 
“The Gap.”
