PTEROPHORID^-AMBLYPTILUS. 359 



followed by a chocolate band which crosses both lobes ; at the 

 anal angle is a dark chocolate spot or blotch ; apical area 

 minutely mottled with yellow-brown and white; cilia similar. 

 Hind wings divided into slender lobes, pale golden-brown 

 with cilia of the same colour, except that the hind lobe 

 is spotted along the dorsal margin with black, and has a 

 black and white tuft. Female similar, hardly stouter. 



Underside of the fore wings dark reddish-brown ; costa 

 dotted with white, and having a white triangle and slender 

 transverse lines before the apex. Hind wings shining smoky- 

 brown. Body brown, the legs white, with long brown 

 cloudings. 



On the wing in Juue and July, possibly after hybernation, 

 and appai'ently as another generation in August and through- 

 out the autumn, even emerging in October and November, 

 but whether as a third generation, or only a second, or even 

 a deferred emergence, is not clearly ascertained. 



Larva bristly, cylindrical ; head pale yellow, with the 

 lobes and ocelli black ; body dusky pale green with a bright 

 green dorsal line, and paler green subdorsal lines. 



September and October on i<tac]ujs sylvatica and ;S'. palustru, 

 feeding mainly upon the blossoms. This I give separately as 

 a description which I have taken myself ; but there is great 

 apparent confusion as to times of appearance, food-plants, 

 and varieties of the larva. Mr. Porritt has reared larvae 

 from the same kind of food-plant, but having the ground 

 colour deep purple, the dorsal stripe smoke-coloured, and 

 subdorsal and spiracular lines white ; others green, tinged in 

 front with pink, and having the dorsal and lateral lines as 

 just stated. As food plants different observers mention 

 Ononis spinosa and 0. arvcnsis, Mentha, CUnopodium vulgarc, 

 Geranium rotundifolium, Euphrasia lutea and E. officinalis, 

 and the buds and blossoms of the scarlet garden geraniums . 

 and July and the beginning of August as times of feeding. 

 Mr. Buckler's larvae fed in July.
