a roughly triangular brown blotch on each side at base ; dorsum 

 of abdomen with hind borders of all segments, and on second

 median stripe and pair of admedian spots drab-grey or smoke- 

 grey, seventh segment with spots but without median stripe ; 

 wings light sepia-coloured, light markings milky, sharply de- 

 fined though rather coarse, rosettes well-marked, apical sinuous 

 mark indistinctly bifurcate ; legs clove-brown or dark seal- 

 broivn, middle femora except tips lighter, a single band on 

 front tibia near base, two bands on middle and hind tibia, first 

 joint of middle and hind tarsi except tip, and bases of next 

 three joints buff or cream-buff, band on front tibia narrow. 



Head yellowish grey ; frontal callus mummy-brown, narrow, 

 extending from eye to eye, partly divided in middle line by 

 a triangle of yellowish pollinose ground-colour which descends 

 from front, upper margin of callus curved, extremities of 

 callus slightly tapering ; a distinct dark seal-brown median 

 spot below callus ; face with a more or less distinct dark 

 streak on each side, near lower inner margin of each eye, 

 and a very distinct small round black spot below each an- 

 tenna ; lateral frontal spots clove-brown, conspicuous, not in 

 contact with eyes, median frontal spot small or indistinct; 

 palpi isabella-coloured, terminal joint rather narrow, elon- 

 gate, blunt at tip, clothed on outer side with black hair ; first 

 joint of antenna brownish buff, scarcely swollen, clothed like 

 second joint with black hair, second joint ochraceous buff, 

 its upper angle moderately produced, third joint seal-brown, 

 lighter at base, moderately elongate, last three annuli clove- 

 brown. Thorax : three grey stripes on dorsum of usual 

 type, very slender and parallel to each other, median stripe 

 continuous or practically so, admedian stripes more or less 

 indistinct after triangular expansions beyond transverse

 Abdomen : dorsum with hind borders of segments clothed 

 with yellowish hairs, sides of segments smoke-grey; venter 

 smoke-grey, clothed with short, appressed, yellowish hairs, 

 a broad dark brown median stripe, interrupted on hind 

 borders of segments, extending from third or fourth segment 

 to tip. Wings : extreme base semi-hyaline ; alula with a 

 pale border all round ; in axillary cell, light loop round 

 proximal angle connected by a broad mark, along or close to 

 hind margin, with extremity of zigzag downward process from 

 proximal rosette ; apical sinuous mark broader at its upper 

 extremity, immediately below tip of second longitudinal 

 vein ; beyond apical sinuous mark two more or less distinct 

 light spots in second submarginal cell just before tip of wing,
