113 LEPIDOPTERA. 



1. D. Archippus, Fal. ; plexippus, L. — Expanse 4 

 inches. Tawny, with black nervures, and white-spotted 

 black hind margin. 



Tawny, with nervures and margins black. Fore wings with 

 the apical region to the middle of the costa also blackish, and 

 enclosing six or seven irregular white spots slightly tinged 

 with reddish, and usually three, more or less distinct, ovate, 

 fulvous blotches between nervures. Fore and hind wings with 

 a broad black band to the hind margins, enclosing a con- 

 tinuous double row of white, or yellowish-white, small spots. 



Female similar, slightly paler, but the nervures broadly 

 suffused with dark scales. The larger whitish spots sometimes 

 yellow. 



Under side of the fore wings similar to the upper, except 

 that there is a broad blotch, composed of oblong cream- 

 coloured spots, before the apex ; of hind wings shining pale 

 ochreous or buff, with black nervures, and the black margin 

 spotted as on the upper side. 



August, September, and October. 



Larva cylindrical ; black ; transversely striped throughout 

 with yellow and white bands, and having two long, black, 

 slender, soft, but upraised, fleshy tentacles, pointing for- 

 wards, on the second segment, and two more, not so long, on 

 the twelfth, pointing backwards. When very young, pale 

 greenish ; quite cylindrical, the tentacles not developed, but 

 indicated as black points. As it grows the stripes begin to 

 appear, and after the first moult the tentacles are noticeable, 

 and become longer at each change of skin. They are shed 

 with the skin, the new ones being found at first after the 

 moult to be mere soft knobs, which very soon unfold, and 

 swell into their proper form. 



On Aschyias. May and August, or even all through the 

 summer. (Riley.) 



PrPA large and very stout, without projections, except a 

 distinct rim, or projecting edge, having a milled appearance
