178 LEPIDOPTERA. 



arched ; apex and hind margin rounded ; dorsal margin also 

 a little filled out ; texture very silky and delicate ; pale pink 

 clouded with pale olive-brown and pale chestnut ; first and 

 second lines undulating, white, not sharply defined, but the 

 latter is joined in the middle to another white line which 

 accompanies it to the costa, and also throws off above the 

 middle a broad white cloudy streak to the apex of the wing ; 

 from this last, just below the tip, a faint interrupted white 

 subterminal line passes to the anal angle, where it spreads 

 into a small whiter blotch ; before the first line arises an 

 olive-brown or pale tawny dorsal blotch which attains the 

 second line, and at its highest point, which is more than half- 

 way across the wing, is capped by a black elongated spot ; 

 this is edged outwardly by a curve of the white line which 

 branches from the second ; where these two divide is a cluster 

 of black dots, and another cluster lies at the inner edge of 

 the dorsal blotch ; costa mainly shaded with pale olive-brown ; 

 hind marginal region broadly with pale olive-tawny or 

 purplish-chestnut forming a large ovate blotch, the extreme 

 margin shaded, with fulvous ; cilia purplish-brown. Hind 

 wings silky dusky white, the nervures faintly brown and the 

 hind margin tinged with smoky-grey ; cilia white shaded 

 with brown. Female similar. 



Underside of the fore wings dusky white dusted all over 

 with smoky-brown. Hind wings white rather dusted with 

 brown, and the nervures broadly indicated in the same. Body 

 and legs light pinkish-brown. 



Vevj constant in colour and markings, variation being- 

 shown only in the whiteness or pink shading of the ground 

 colour. 



On the wing at the end of May and in June. 



Larva having sixteen feet, the fourth, fifth, and sixth seg- 

 ments much enlarged beyond the rest of the body, and the 

 twelfth slightly humped ; the colour generally is a rich warm 

 brown, with a row of eight dusky-red diamonds clown the back
