PHYCrnD.€.—PLOD lA. 63 



Anteunaj of the male stout, particularly so toward the 

 base, shining purple-brown ; palpi horizontal, porrected, 

 purple-black ; head and thorax purple-brown, with a some- 

 what metallic gloss ; abdomen glistening whitish-brown. 

 Fore wings not very long but narrow ; costa arched ; apex 

 rounded ; hind margin gently curved ; colour from the base 

 nearly to the middle pale yellow ; then abruptly edged by a 

 nearly perpendicular black shade, which seems to represent 

 a displaced first line ; remainder dark purple, purple-crirnson 

 or purple-black, or shading from the larter to either of the 

 former ; discal spot faint, triangular, paler purple ; closely 

 followed by a still more obscure, oblique, straight purple- 

 black second line ; a black line edges the apex and hind 

 margin ; cilia shining dark purple. Hind wings pointed at 

 the apex, flatly rounded behind ; shining white, faintly 

 streaked and shaded with brown on the nervures; cilia 

 white. Female similar. 



Underside of the fore wings shining pale bronzy-purple. 

 Hind wings shining white, shaded with brown. Body and 

 legs purple-brown. 



Variation, as already shown, is mainly in the colour of 

 the outer half of the fore wings, from bright light purplish- 

 red to dark purple-brown or purple-black. 



On the wing from July to October, probably in two gene- 

 rations — though there seems to be a continuous emergence, 

 and in the United States it is supjiosed that five jor six 

 generations succeed each other in the year. 



Larva cylindrical; head polished, sienna-brown; the 

 lobes rounded ; mandibles prominent, dark-brown ; dorsal 

 plate also polished, semicircular, sienna-brown ; body almost 

 uniformly very pale straw-colour, the alimentary vessel 

 showing through the skin, forming a darker dorsal stripe ; 

 the skin has a flabby translucent appearance ; tips of pro- 

 legs dark-brown ; there are no other noticeable markings.
