above internal margin. Two prominent teeth, elsewhere the line is 

 but very slightly irregular if we except the usual prominent inflection 

 above internal margin. A brown shade baud follows the t. p. line, largely 

 interrupted centrally. Sub-terminal line, pale greyish, sub-dentate. 

 Terminal space concolorous with the rest of the wing, clouded with 

 brown sub-apically and slightly above internal angle; a series of con- 

 nected, terminal interspaceal brown dots. Fringes dark, interrupted 

 slightly with grey. 



Posterior wing bright yellow. The median black band is irregular, 

 — closely preceded superiorly by a luniform streak which shows more 

 plainly on the under surface and is usually, especially in the female, 

 more or less absorbed by the baud, — greatly constricted at within its 

 middle and joining within internal margin a parallel basal black shade 

 band. Terminal black band interrupted inferiorly, forming an isolated 

 black spot before anal angle. Fringes whitish, interrupted broadly 

 five times with black below the yellow apical patch. 



Under surface very pale yellow. A very irregular sub-terminal 

 black band on the primaries, tapering to either margin and closely pre- 

 ceded by a luniform discal spot which is more or less merged with the 

 band and gives this a furcate appearance. In the female this band is 

 broader, entirely absorbing the discal spot. Terminally the wing is shaded 

 with blackish, leaving the edges paler. Fringes moi'e interrupted with 

 greyish than on the upper surface. On the posterior wings the middle 

 band is similarly associated with that on the anterior wings, but does 

 not attain the costa. Head, thorax and appendages similar to anterior 

 wings in coloration, with dark lines on the prothorax and tegulre; cen- 

 trally the discal scales show a brown tinge. Abdomen above, dusky tes- 

 taceous; beneath, with under surface of thoracic parts, and inner surface 

 of legs, white; outer surface of legs pale brownish; tarsi sub-annulate.
