82 LEPinOPTERA. 



angulated and slightly projecting; hind margin, immedi- 

 ately below it, straight and oblique to a slight depression, 

 then it expands and is rounded off: colour golden yellow- 

 brown, rather paler along the dorsal margin ; the longitu- 

 dinal stripe not very broad, brilliantly pearly-white, slightly 

 forked just beyond the middle of its lower edge, wedge- 

 shaped at the end ; closely beyond it, and only separated by a 

 black-brown oblique streak, is a small pearly white blotch ; 

 below this are several lines of black dusting on the nervures; 

 another white stripe from the base, but very narrow, lies 

 along the costa to the middle : beyond this are two oblique 

 wedge-shaped pearly white streaks, pointing downward, the 

 first having beneath it a slender longitudinal silvery 

 white dash, the second becoming, with a decided elbow, a 

 transverse line, brown, edged with silvery white ; from this 

 elbow a white wedge-shaped spot runs into the apex of the 

 wing ; lower hind-marginal space pale purplish-grey dusted 

 with golden-brown ; cilia white against the apical white 

 spot, purplish-grey below, but intensely glossy, and edged 

 with a golden sheen. Hind wings very ample, rounded behind, 

 smoky pale purplish-brown : cilia paler. Female similar, 

 or more whitish -golden-brown. 



Underside of the fore wings smoky purplish-brown ; apex 

 and hind margin silvery yellowish-white. Hind wings 

 smoky pale purplish-brown. Body and legs pale golden- 

 brown. 



Not variable to any extent, except that specimens from

 brown than those from the north, and than those which 

 I have seen from abroad.
