id8 LEPIDOPTERA. 



indicating the orbicular stigma, and beneath it a sort of 

 duplicate stigma is enclosed by a similar white and pink 

 margin ; reniform very faintly indicated by a partial white 

 edging, olive-brown divided by a pink shade ; hind marginal 

 line silvery-white ; cilia similar, shaded and faintly inter- 

 sected with pale pinkish-brown. Hind wings rounded, the 

 hind margin only faintly sinuous ; pale smoky-brown faintly 

 banded in the middle with darker brown ; cilia white inter- 

 sected with brown. Female very similar. 



Underside of the fore wings smoky olive-yellow ; dorsal 

 margin broadly pearly-white ; beyond the middle are two 

 oblique smoky transverse stripes. Hind wings paler smoky- 

 yellow, with a curved and sinuous transverse smoky-brown 

 central stripe, followed by a similar stripe nearer the hind 

 margin ; cilia golden-brown. Body and legs pale yellow-brown. 



On the wing in June and July. 



Larva bluish-green, with four long black raised dots on the 

 back of each segment, having between them a deeper black- 

 green dorsal line, and two slender longitudinal white lines ; 

 spiracular stripe yellow ; spiracles and raised dots black ; 

 undersurface grey-green dotted with black ; head and legs 

 black, the latter with angular green markings. (Hofmann.) 



May and June on Aconitum Jycodonum and probably allied 

 plants. Curtis says Thalictvum aquilegifolium , but this seems 

 to require confirmation. 



Pupa dark green with brown shadings. In a delicate white 

 cocoon spun among leaves. (Hofmann.) 



This is one of our rarest insects, and its habits here are 

 almost unknown. On the Continent it is said to prefer moun-

 Dale, now in the possession of his son, are two specimens
