disc, there deflexed upwards aud running to costa just beyond f ; 

 a white streak, internally very irregularly margined, from | of 

 fold to apex of wing, confluent above middle with a white band 

 along hindmargin ; inner margin almost entirely suffused with 

 white, and between first and second white streaks ground-colour 

 mixed with white scales ; a rather indistinct, outwardly curved, 

 wavy blue-whitish subterminal line, bordered with ground-colour 

 where it cuts the white subapical band; hindmarginal line strong, 

 black, marked on lower half with about five black spots ; cilia 

 white, with fuscous-grey parting-line, towards anal angle almost 

 entirely grey -fuscous. Hindwings rather pale fuscous-grey ; 

 cilia hardly paler.

 species. 



Or. concmnellus, WTcr. Gat. 165. 



8" — 9". Head white, labial palpi twice as long as head, white, 

 on sides fuscous. Antennae whitish. Thorax white, lateral 

 margins dark fuscous. Abdomen whitish. Legs ochreous- 

 whitish internally, greyish-fuscous externally, tarsi with 

 whitish rings at apex of joints. Forewings elongate, slightly 

 dilated ; apex produced, acute, appearing from the cilia 

 slightly falcate, hindmargin beneath apical indentation hardly 

 oblique, rounded beneath ; dark fuscous or blackish, blackest 

 along costa ; a straight broad silvery-white streak from base to 

 apex, upper margin of basal half almost touching costa, apical 

 half gradually more attenuated ; a rather narrower silvery-white 

 streak along inner margin from base to anal angle ; a slender 

 bluish-white subterminal line, cutting the longitudinal streaks, 

 proceeding from beyond f of costa obliquely outwards, sharply 

 angulated on first streak, thence tolerably parallel to hind margin, 

 angulated again on second streak, ending before anal angle ; on 

 costa before subterminal line are two more oblique slender white 

 streaks, and between it and apex another less distinct, not oblique; 

 behind subterminal line the space between the two longitudinal 

 streaks is cinereous-grey, sprinkled with white scales, and cut by 

 three longitudinal black lines ; the disc immediately before sub- 

 terminal line is also more or less sprinkled with cinereous-grey
