lateral areas of silvery ones, two small circular areas of golden scales 
in the centre of each segment. A few long white hairs along the 
apical border of each segment. Venter almost entirely white, with 
creamy scales, a few black scales near the apical borders of the 
segment. Wings, extremities of the long veins with long narrow 
scales and short broad ones, upper forked cell longer, but about as 
broad as the lower, its stem half its length ; the stem of the lower 
fork cell nearly as long as cell. The posterior cross-vein half its own 
length behind the mid cross-vein. Halteres, with pale stems and 
knobs. Legs black, unbanded, femora and tibiae with many yellow 
scales beneath, fewer in the metatarsi and tarsi; knee spots small. 
Ungues all equal and uniserrate, the tooth large. 
Length .—4 mm. 
. Head, yellow area in the centre more extensive, broad, flat, 
yellow scales abundant. Palpi black, terminal joints slightly inflated, 
a little larger than the proboscis ; both terminal joints and apex of the 
antepenultimate densely covered with long hairs, some very stout 
ones at the apices of the joints. Mesonotum with the band of golden 
scales conspicuous. 
Terminal clasp segment slender, curved, slightly swollen in the 
middle, apical spine blunt, about one-fifth length of limb. Basal clasp 
segment with a large apical lobe ; claspette a well developed lobe 
near the base covered with spines (no long ones present). Harpes, 
bases villous with fine hairs, at the apex of each a recurved sickle-like 
portion. Harpogones deeply infuscated, with a strong recurved spine 
on each. Unci membranous, separated, each terminating in a point. 
Setaceous lobes pyramidal with about ten strong curved spines along 
the internal borders only. Ungues of fore and mid legs unequal, the 
larger claw with two teeth, smaller with one. Ungues of hind legs 
equal and uniserrate. 
Length .—4 mm.” 
The adult larva was also described, with a note to the effect that 
it superficially resembled that of A. auratus , Grabham, and still more 
so that of A. hemisurus , Dyar and Knab.

Many forked upright yellow scales at the back; a few forked upright
