Palpi projecting fully the length of the head beyond it ; the second joint thickly clothed,

straight, the apical margin oblique, slightly impressed below the apex — dark brownish 
fuscous, with several shining, short, geminated costal streaks ; the third pair from the apex 
blending into a shining steel-blue double band, outwardly angulated above the middle, the 
others towards the apex being also tipped with steel-blue metallic streaks ; the ocelloid patch 
is bright shining metallic steel-blue on its inner and outer sides ; a square dirty-whitish sub- 
lustrous patch on the middle of the dorsal margin is interrupted by three slender brownish- 
fuscous lines, the middle one being the thickest : cilia shining brassy whitish, with a slender

Head thickly clothed with long hair-like scales, projecting forward between the antennae: 
palpi also roughly clothed with long hair-like scales, which extend considerably beyond the 
end of the short apical joint, projecting twice the length of the head beyond it; the second 
joint thickened in the middle above, almost triangular ; the apical joint very short, obtuse. 
Fore wings with the costa evenly arched, the apex produced and depressed, but scarcely 
falcate ; the apical margin slightly oblique, concave ; dorsal margin rounded ; the male 
without a costal fold ; veins 12, all separate at their origin. Hind wings with the outer 
margin slightly indented below the apex, rather wide, with long cilia ; the median vein with 
long hairs above at the base ; vein 5 arising near the same point as 4. The inner spur of 
hind tarsi considerably longer than the outer.
