3" — 3-29" against 2-5" — ^2-75" as recorded by Bingham and 2'9" as recorded 

 by de Niceville. 



Male. Upperside : much darker. Forewing : the post-discal area less 

 conspicuously paler than rest of the wing. Underside : much darker ; markings 

 dark red-brown and not light red-brown as in the typical form. 



Female. Very similar to the male and only differs on the upperside in 

 having the post-discal dark band more conspicuous and the area beyond it 

 paler; the costal and preapical spots more conspicuous. Underside \ brighter 

 and more golden brown. 



Both sexes taken during August and September on Kabru Peak, 

 Manipur, 7,000' — 8,400' and males in the Naga Hills at Kirbari, Takabama, 

 and on the Hill above Kohima at about 7,000' during the same months. 



Although I have obtained a good series of both sexes it is by no means 

 a common butterfly and appears to be on the wing only in August and 

 September. 



Lethe satyavaxi, de N. 



A female of the dry-season form was obtained on the Barak River, 

 Western Manipur Hills, in April. 



The 2 type in the de Niceville collection caught on May 18th is a 

 wet-season form. The dry -season for in differs from it on the upperside in being 

 greyish-brown and not red-brown and in having the whitish terminal area 

 much more conspicuous. Underneath the colour is also greyish-brown and 

 not red-brown and the pale terminal area not so distinctly lilacine and the 

 ocelli not so large. 



This is an exceedingly interesting capture as the two type specimens, 

 taken by Professor Wood-Mason at Sibsagar, have hitherto been the only 

 ones recorded. The male still remains unknown. 



Lethe siderea, Marshall. 



The female which according to Bingham is unknown differs somewhat 

 from the male. Upperside: paler brown than the male. Forewing: cell 

 and bases of interspaces 3, 4, 5 and 6 darker than the rest of the wing ; this 

 dark area outwardly well defined and sharply angled at vein 4, followed 

 by a pale brown transverse band ; a preapical row of pale spots in inter- 

 spaces 4 — 6 and a diffused pale area in interspaces 7 and 8. Hindwing : 

 the ocelli on underside showing through more or less as dark spots. Under- 

 side. Forewing : the dark discal area sharply defined as on upperside but 

 continued into interspace 2 ; the transverse pale brown post-discal band as 

 on upperside but very diffuse on outer edge, followed by a preapical row 

 of white spots in interspaces 3 — 7, the lower spot sometimes absent ; base 

 of interspaces 7 and 8 pale brown. 



Hindwing as in male. 



Expanse : ? ? 2-15"— 2-23." 



Both sexes were obtained by my Native Collectors at 6,000' — 8,400' from 

 May to October, both in the Naga Hills and in Manipur. Females were 

 generally found higher up than the males. 



It is by no means such a rare insect as I previously thought. 



Lethe kanjupkula, n. sp. (PI. I, Figs. 5, 6 ; S , ?)• 

 Male, dry-season form. Upperside : very similar to L. siderca in 

 shape of wings but the colour is greenish-brown and not coppery-brown 

 as in that species. Forewing unmarked. Hindwing four faint dark spots 

 in interspaces 2 — 5. Underside: dark fuliginous brown. Forewing ; a faint 

 much curved post-discal band, lighter than the ground colour, commencing 

 at the costa just beyond apex of the cell and ending at the tornal angle. 

 Three sub-apical dark spots with blurred whitish centres in interspaces
