scales. Metanotum deep brown. Abdomen black with violet reflec¬ 
tions, basal segment with long white hairs, apex of each segment 
bordered with a few long white hairs. Lateral apical patches of 
white scales in the posterior segments. Venter yellow, densely 
covered with broad yellow scales, among which are interspersed a few 
violaceous scales, especially near the bases of the segments. Legs 
dark metallic violet, with well marked knee spots on all the femora. 
Tibiae, metatarsi and tarsi of hind legs densely scaled; third and 
fourth tarsi of hind legs white scaled. All the ungues uniserrate and 
equal. Wings, first sub-marginal cell longer and narrower than the 
second posterior, its. stem less than half its length. Stem of second 
posterior cell a little shorter than the cell; posterior cross-vein more 
than its own length behind the middle cross-vein. Halteres with 
pale stems and knobs. 
Length .—5 * 5 mm. 
d*. Antennae pale brown, second joint slightly inflated, thickly 
clothed with a number of long stalked black scales, with fan-like 
heads and long black hairs. Proboscis black, with a faint band on its 
lower third. Palpi longer than the proboscis by the two terminal 
joints. Two terminal joints inflated and densely black scaled, a 
number of long black hairs along the under surface, a few black hairs 
on the apex of the terminal joints. Antepenultimate joint inflated at 
apex, a few black hairs on the under surface near the apex. A single 
narrow band of golden scales on its lower third. Terminal segment 
of clasp greatly dilated in the middle. Harpes, limb extending into a 
thin lamina at the apex, from the internal border of which a number 
of long thin flattened hairs arise; at the tip two convoluted processes 
are attached. Harpogones with strong recurved tips and two stout 
thorn-like tubercles on their convex surfaces. Unci deeply chitinized, 
adherent along their internal borders. Setaceous lobes absent. 
Ungues of fore and mid tarsi unequal, the larger with two teeth, a 
long blunt one and a small basal one; the smaller with a minute 
basal tooth. Ungues of hind tarsi uniserrate and equal. 
Length .—5 ‘ 5 mm. 
The following points were noted in the adult larva : Fully grown 
adult larva nearly five-sixteenths of an inch long. Antennae large and 
prominent, longer than the head, strongly curved about the middle, 
deeply fuscous except at the base. Slightly inflated in the lower half. 
Tuft at the middle of about six fine feathered hairs not exceeding half 
the antennal shaft in length. Apex with three or four short spines. 
Surface covered with stout chitinous spines. Mentum deeply infus- 
cated, somewhat narrowly triangular; teeth dark and numerous; 
apical tooth large and prominent. Both upper and lower epistomal 
hairs are double and feathered, extending beyond the margin of the 
head. Ante-antennal tuft of 8-10 feathered divisions. Body glabrous 
except for a few small scattered dondritic hairs. A small dorsal patch 
of minute thorn-like spines, arranged in curved lines, on each segment
