spatulate tail of moderate length on third median nervule. Fore-wing : 
costa with a black border, rather wide from base to a little before 
niiddle, thence much narrower till it meets hind-marginal border; the 
latter broad apically, and enclosing an elongate sub-ovate spot of the 
^round-colour between fourth and fifth subcostal nervules, but narrow- 
ing very considerably to posterior angle, — its inner edge usually more 
or less irregular, and only slightly and unequally dentating the ground- 
colour on nervules, but in some of the more strongly-marked speci- 
mens emitting deep and almost regular nervular dentations ; along its 
outer edge on hind-margin itself, a series of very small thin inter- 
nervular spots of the ground-colour — rarely obsolescent ; middle disco- 
cellular nervule occasionally marked by a very small black dot or a 
black line. Hind-wing : discal Mack hand exceedingly variable as regards 
width and continuity, — when completely continuous, it is always nar- 
rower between second and third median nervules (where the wider 
and more complete interval occurs in the interrupted state ; the other 
interval, less frequent than the first, being between second subcostal 
and radial nervules) ; inner edge of this band variably uneven, slightly 
diffused, sometimes denticulating ground-colour on nervules ; but not 
unfrequently more or less pierced itself by small nervular dentations 
of the ground-colour; outer edge always presenting large and promi- 
nent nervular dentations ; along hind-margin a series of narrow more or 
less lunulate black markings, which in the most strongly-expressed 
specimens form a thoroughly continuous serpentine streak (touch- 
ing on most nervules the outer dentations of discal band, and 
leaving inter-nervular hind-marginal lunules of ground-colour), 
but in others are partly or altogether and widely separated; tail 
with a median black line of variable definition, and almost always 
with a thin black edging on each side, — in strongly marked 
specimens these streaks are more or less diffused and confluent, 
making more than basal half of the tail black or blackish ; along hind- 
marginal edge (including tail) a more or less decided tinge of ochre- 
yellow; just before anal angle, in discal black band, a small lunate 
spot of the ground-colour, sometimes very indistinct. Under side. — 
Hind-wing and hordcrs of fore-iuing diUl ochrcous-yellow, — the former 
paler or much paler in basal half, and with discal band ^represented 
hj ferruginous-lroiun. Fore-iving : costal border more or less blackish 
inwardly as far as middle, especially at and near base ; from lower 
radial nervule, the inner side of hind-marginal border is blackish and 
this dark edging increases in width downward till at posterior angle 
it occupies all the border- inter-nervular folds sometimes defined by 
brown rays crossing yellow-ochreous part of border. Hind-wing : 
throughout marked with more or less distinct inter-nervular brown 
rays (in some of the more strongly marked specimens becoming blackish 
and often diffused where crossing discal band) ; three similar but usually 
thinner and darker longitudinal rays in discoidal cell, divergent from
