-LYCANID., TICHERRA. 407 
Genus 166.—TIOHERRA, de N. (PLATE XXVIII), 
Ticherra, de Nicéville, Proc. Zool. Soc. Lond., 1887, p. 457. 
“Closely allied to Cheritra, Moore, but differs in the male in the absence of the 
secondary sexual characters on the costal margin of the hindwing on the upperside ; the 
third subcostal nervule of the forewing springing from the costal nervure much nearer its 
apex, consequently being shorter ; the discoidal cell of the hindwing longer, the disco-cellular 
nervules being much more outwardly oblique.” 
‘Type, Zicherra acte, Moore.” (de Nicéville, 1. c.) 
Two species only come into this genus as far as I can ascertain. 7. acteis a common 
Himalayan species, occurring also in Assam and Upper Burma. 7. symira, Hewitson, is 
probably an aberration of 7. acte, and was described from Sikkim. In 7. acte a very marked 
seasonal dimorphism occurs, the form on the wing during the rains has a brilliant orange 
underside, whilst that found in the dry-season, when the vegetation is much more scanty and 
arid, is of a brownish hue, closely simulating the shade of a dead leaf. Mr. Doherty notes 
on this subject : ‘‘ The very distinct dry-season form, non-ocellate and dusky fuscous below, 
was first seen in November” at Margherita, in Upper Assam.

DESCRIPTION: FEMALE. ‘‘ UPPERSIDE, 40th wings dark smoky-brown. Hindwing with 
three spots of white near the anal angle, ¢az/ and anterior margin whitish. UNDERSIDE, both 
wings reddish chrome-yellow, with an indistinct undulating line crossing the wings, termi- 
nating abdominal'y on the 4indwing in separate lighter spots, near the anal angle brownish, with 
two black spots bounded anteriorly with metallic blue.” (Adoore, |. c.) MALE. UppErsipg, 
both wings dark purple, the outer margin narrowly black. Ainxdwing with the anal angle 
broadly black, bearing inwardly two small white spots divided by the first median nervule, 
four short white lines on the margin between the veins from the third median nervule to the 
anal angle. Two /ai/s, which are blackish towards the base, then suffused with ochreous, 
with a dark middle line, quite white towards the tip. Cv/ia of the forewing black, of the 
hindwing ochreous anteriorly, whitish-ochreous posteriorly. UNDERSIDE, doch wings coloured 
and marked as in the female. 
The figure shews both sides of a male specimen of the wet-season form from Bhutan in 
my collection. 
Dry-season form. 
* MALE and FEMALE. UNDERSIDE, doth wings differ from the typical rainy-season form 
in the ground-colour being cinnamon-brown instead of rich ochreous-orange; the markings 
in the discoidal cells and the fine linear discal fascize are also much more prominent.” Hind- 
wing with the two black spots at the anal angle and the silvery blue metallic line above 
them obsolete,
