3. Upper side that of a pale Hiibneri, but the distal third of 
the hind wing is faintly suffused with dirty whitish before the 
irregular dark marginal band. Under side dirty greyish white, 
with pale greyish brown striolation, which is sometimes sparser or 
wanting on the distal half of the hind wing; fore wing with a 
faint oblique post-median dark line, and a faint submarginal dark 
line arising in the posterior angle, and obsolescent in cell 3 or 
thereabouts; hind wing with a faint irregular submedian dark 
line, which is angularly produced outwardly on vein 5 or there- 
abouts; ocelli punctiform, small, or wanting ; clasp similar to that 
of kasmira and ceylonica (Pl. I., figs. 6, 8). 
?. Similar to the g, but larger and paler. Expanse, 36—40 mm. 
This insect might easily be passed over as one of the 
pale extremes of the cold weather form of Hibneri ; 
the form of the clasp, however, shows that it has really 
nothing to do with Hiibneri, but is more probably an in- 
teresting case of an incipient species which has made 
some little progress in a course of colour variation from 
kasmira to ceylonica, or vice verséd (but at present much 
nearer the former), since the form of its clasp is practi- 
cally identical with that of either of those species. The 
feeble pale suffusion on the upper side of the hind wing is 
appreciable in the majority of specimens, though wanting 
in some, and rather less evident in the female. We are 
indebted to Col. Swinhoe for lending us his cotypes, and 
furnishing us with specimens for dissection. Some 
misapprehension with regard to this species has been 
caused by the fact that its author distributed a small 
pale form of Marshalli under the MS. name of jocularia, 
’ and afterwards published the latter name in connection 
with the insect above described. This species is not in- 
serted in its place, which would be between kasmira and 
ceylonica, as we had not the opportunity to examine 
authentic specimens until after this paper was in type.

This insect, which is from Madagascar, is probably 
not an Ypthima; if it is, it may be distinguished by the
