Antenne brown, indistinctly annulated. Head brown, paler at 
the sides. Palpi greyish-brown, Prothorax with greyish hairs. 
Mesothorax reddish-fuscous. Anterior wings with a deep notch 
in the apical margin ; in the male yellowish-grey, thickly sprinkled 
with brown spots; pterostigma, two rows of small dots towards 
the dorsal margin, and large spots on the apical margin, dark 
fuscous, the apical spots alternating with yellowish ones ; fenes- 
trated spot oval, large; anastomosal space also large, often con- 
fluent with the fenestrated spot and then forming one large 
crescentic space ; veins fuscous ; in the female the anterior wings 
are paler and more uniform, yellow, very closely irrorated with 
small confluent brown spots more or less intense, the apical por- 
tion entirely brown; pterostigma, and three smaller spots on the 
apical margin before the notch, fuscous; the fenestrated spot is 
narrow, often indistinct, the anastomosal space broken up into 
several smaller spots. Posterior wings hyaline, apex brownish- 
yellow, with two opposite sometimes confluent fuscous blotches 
irrorated with paler ; in the female the apex is brownish-yellow, 
without fuscous markings ; veins brownish. Legs pale testaceous, 
with black spines, apices of the tibiz and tarsi slightly fusces- 
cent. Abdomen dull greenish in life. In the male the upper 
margin of the last abdominal segment is bisemarginate, somewhat 
produced in the middle, over each notch is a broad crescentic 
black spot; app. sup. flat, somewhat truncated at the fuscous 
tips; app. intermed. broad, black, generally concealed; app. 
inf. consisting only of a broad base with a few long hairs. In 
the female the superior valves form two acute diverging tuber- 
cles; lateral valves large, broadly emarginate, the lower portion 
dilated. 
Expanse of fore-wings 11—15 lin. 
Larva with the head and two first thoracic segments of an
