cular area. Legs: Femora and tibiae each with 
apical patch of silvery=white scales anteriorly 
(that on tibiae is largely dorsal); fore and 
mid tibiae dark, some pale scaling posteriorly; 
hind tibia dark posteriorly. Wing: Wing with 
spot of silvery-white scales at base of costal 
vein. Abdomen: Tergite I with lateral band of 
silvery-white scales; III-VII with basal bands 
of brownish-yellow scales, VIII largely pale- 
scaled. Sternites with brownish-yellow scales 
basally, brown scales apically; VIII covered 
with silvery-white scales (since this sternite 
is dorsal on most specimens taken, it creates 
a very distinctive dorsal abdominal marking), 
not possessing distinctive hair tufts. Termin- 
alia: Basistyle without lobes; tergal surface 
with numerous very small setae, these not 
extending to lateral margin setae along distal 
portion; sternal surface with a regular longi- 
tudinal row of very long hairs near to mesal 
margin. Dististyle distinctively shaped as fig- 
ured. Ninth tergite strongly concave medially. 
Female. Differs from the male mainly as 
follows. Proboscis dark. Vertex with dorsum 
narrow-scaled, a median anterior diamond-

shaped group of these dusky, the remainder 
golden; the lateral broad-scaled area creamy- 
yellow except for dark patch at dorsal margin 
and sometimes one on a level with apn. Apn 
with a few narrow yellowish scales; ppn with 
a few dark narrow scales dorsally. Subspira- 
cular area with a few dusky hairs. Tergites 
with a basolateral patch of silvery-white scales, 
the basal bands (which are variable in occur- 
rence and width) either separate from these, or 
only narrowly connected. Sternites largely 
covered with brownish-yellow scales, some 
apical dusky scales usually present. 
LARVA: Similar to pampangensis, but differ- 
ing chiefly as follows. Spicules on antennal 
shaft sparser and not as heavily developed; 
antennal hair tuft with 5-13 branches. Head 
hair 5 with 3-4 branches; hair 6 with 3. Men- 
tum with 16-18 lateral teeth. Comb with 
20-26 scales in a patch, the scales blunt, 
fringed laterally and apically and without an 
enlarged central spine. Siphon index 3. 5-3. 9, 
acus large; 18-21 pecten teeth, all with 1-3 
ventral denticles, the distal 1-2 teeth more
