spatulatc tail of moderate length on third median nervule. Fore-iving : 

 costa with a black border, rather wide from base to a little before 

 middle, thence much narrower till it meets hind-marginal border; the 

 latter broad apically, and enclosing an elongate sub-ovate spot of the 

 ground-colour between fourth and lifth 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-iving : discal black hand cxceedinglg 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 baud variably uneven, slightly 

 diffused, sometimes denticulating ground-colour on nervules ; but not 

 unfrequeutly 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 luuules 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 borders of fore-wing dull ochrcous-ycllow, — the former 

 paler or omcch paler in basal half, and with disced band represented 

 by fcrruginous-broicn. Fore-wing : 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 ravs in discoidal cell, divergent from
