Genus Trapana, Wlk. 
936. T. vishnu, Lef. 
Sikhim and Bhutan, 1,000 to 6,000 feet. ‘This species occurs at the 
higher elevation in the larva state feeding on Polygonum orientale, 
and all the females I have reared from these high-elevation larve 
have been pale green with a sub-basal purplish blotch. I have re- 
peatedly taken males and females at low elevations nm copula, but here 
the female is invariably bright chrome-yellow with a reddish sub- 
basal patch, and with greenish antemedial and medial lines on the 
forewing. The males of both forms are pale green, the margins of 
both wings of the lower elevation form being more crenulate, and with 
the cilia purplish-brown. It occurs in February, May, July and 
August. A female, recently taken in the Kangra Valley, Punjab, at 
4,500 feet, is of the bright yellow form. 
Genus Hsticens, Moore. 
941. £. pardalis, Wk. 
Sikhim and Bhutan, 1,800 feet up. Common in May, July and 
September. 
Genus OpoNnESTIS, Germar. 
942. O. leta, W1k. 
Sikhim, 1,800 to 5,000 feet. The larva feeds on grasses and forms 
an oval cocoon. The perfect insect emerges in August. Itis not 
common. (I have only once taken this at light on Tongloo at 10,000 
feet, so it must have a very wide range of elevation. [ have a distinct 
species which agrees with the type (?) of O. decisa, W1k., in B, M. 
It has a grey patch in centre of forewing above, and no oblique band 
on forewing.—H. J. E.) 
943. O. divisa, Moore. 
Sikhim. (Both sexes were in Moller’s collection, but I have never 
taken it myself. Sir G. Hampson’s remark as to a Sikhim specimen 
differing in having the inner area of the forewing suffused with yellow 
only applies to one of my two males.—H. J, Z.) 
944. 0. castanea, Hmpsn. 
Sikhim. I do not know this species. (1 also have never seen it.—
