A key to the last six species may be useful. 



Above they are all more or less similar, except that I. puellaris 

 and I. dubia have the marginal black bauds on the hind wings 

 deeper than in the other species ; their distinctive differences are 

 in the colouration and markings of the wings below, as under. 



I. vestalis, Butler, and I. puellaris, males; botli wings below sul- 

 phur yellow, fore wings with three black spots near outer margin, 

 below the median branches; in I. vestalis the centre spot the largest 

 in I. puellaris with lowest spot extending downwards and expand- 

 ing upon the hinder margin; females very similar in appearance, but 

 the band on the hind wings above in I. puellaris is, as iu the males, 

 deeper than in /. vestalis, below the markings are very much as in 

 the male, but the hind wings are flesh colour, the colour being 

 darker in I. puellaris than in I. vestalis.
