406 Mr. G. Talbot on new 



forms, which are absent in the Joicey Collection, has been 

 placed according to the description. 



We are able to distinguish the three species as follows: — 



E. jupiter, Butl. — Fore wing above with black basal area and 

 with well-defined band. Hind wing beneath with the 

 outer edge of discal white band straight. Abdomen 

 black above in both sexes, beneath white in the $ , 

 black or blackish brown in the $ . The fringe of hair 

 on inner margin of hind wing blackish brown. 



E. semjn-onius, Fabr. — Fore wing not black in basal area. 

 The hind wing below with the two black discal lines 

 farther apart, the outer one irregular, not curved so 

 much as in pyrrhus, and not straight as in jupiter. 

 Abdomen white or buff, in the ? brown beneath. 

 Thorax not so dark above as in the other species, and 

 but little darker than the abdomen. The fringe of 

 hair on inner margin of hind wing is white. 



E. pyrrlnis, Linn. — The basal area of the fore wing with 

 glaucous suffusion or entirely creamy- or greyish- 

 white. Basal area of hind wing white or grey. On 

 the hind wing beneath the black line along the outer 

 edge of the reduced white discal band is curved 

 inwards. Abdomen in both sexes mostly buff, dorsum 

 generally darker, in the ? blackish beneath. The 

 fringe of hair on inner margin of hind wing is grey- 

 white or dusky.
