ISO I.EPIDOPTERA. 



followed by another of black streaks or crescents, and this by 

 a third row along the liiud margin, of spots of an oval shape. 

 Sexes similar. Under side of the fore wings like the upper, 

 but with the markings paler, the apex brownish, and the base 

 of the costa white, barred with numerous black streaks. 

 Hind wings yellowish-white, most beautifully marbled with 

 olive-brown, and having a row of round blue spots, ringed 

 with yellow and black, before the hind margin. 



Variable in colour, which ranges from pale reddish-brown 

 to rich pinkish-red, and still more so in the extent and 

 intensity of the dark markings on both fore and hind wings. 

 Occasionally these markings are contracted, the irregular 

 dark stripe across the fore wings separated into distinct 

 spots, and the hind wings very bright in colour ; in other 

 instances they are much extended, the hind wings in par- 

 ticular almost obscured with dark clouding, and some of the 

 round black spots run together into a blotcli. In other cases 

 these round black spots are very distinct and ornamented 

 with brilliant blue centres; in some specimens an additional 

 white spot appears in the apical region of the fore wings, 

 causing the row of four to become five ; and another some- 

 what rare form has all the dark markings golden brown. In 

 the collection of Mr. S. J. Capper is a striking aberration, in 

 which the white spots of the apical region are entirely 

 absent, leaving it totally black ; and the underside of the 

 hind wings brownish, without the usual marbling. Mr. J. A. 

 Clark has a handsome specimen, which possesses a sub- 

 marginal row of white spots on all the wings above ; Mr. S. 

 Stevens, two tawny specimens, devoid of the usual central and 

 dorsal black markings ; and Mr. Sydney Webb, one very 

 similar, another in which the white spots are replaced by 

 tawny, and a third in which the apical row of white spots 

 is further supplemented by one in the red portion of the 

 wings. 



On the wing at the end of July or in August and Sep- 

 tember, and, after hybernation, in May and June or even July.
