always devoid of the wedge-like streaks which are con- 

 spicuous in some other species. Outside this line is an 

 irregular dark brown cloud lying along the hind margin ; 

 orbicular and reniform stigmata rather small, either brown 

 edged with whitish, or wholly whitish or greyish- white ; the 

 space between them often darker brown, sometimes con- 

 spicuously so, forming a somewhat squared spot ; claviform 

 stigma only indicated by a small, uncertain, brownish streak ; 

 nervures in the middle area of the wings, especially the 

 subcostal and median, often indicated in white or paler 

 brown ; between the first and second lines is sometimes a 

 rather slender cloudy brown transverse shade ; costal edge 

 dotted or spotted with brown ; extreme hind margin edged 

 with minute black lunules; cilia light brown, yellowish at 

 the base. Hind wings rather short, apex rounded, hind 

 margin rather sinuous ; whitish, with the nervures brown, 

 and the costal and hind marginal regions clouded with 

 brownish-grey, sometimes faintly and narrowly, often broadly, 

 and sometimes even darkly so toward the hind margin ; in 

 some cases also forming a cloudy grey transverse stripe ; 

 central lunule elongated, grey ; cilia rather long, pure white. 

 Female similar, with the body stouter, the antennte simple, 

 and the fore wings slightly narrower. 



Underside of the fore wings greyish-white, becoming 

 shining white before the hind margin, usually clouded more 

 or less with slate-grey in the middle area ; reniform stigma 

 indicated by a blackish spot, just beyond which is a narrow, 

 angulated, dark grey transverse stripe. Hind wings white, 

 dusted along the costal and hind margins with grey atoms ; 

 a faint transverse stripe of similar atoms lies beyond the 

 middle ; central spot elongated, grey. Body whitey-brown ; 

 legs pale brown, the first pair spotted in front with black ; 

 leg tufts whitish-brown. 



Variable in an extraordinary degree, hardly two speci- 

 mens being precisely alike, and all the varying forms 

 shading insensibly into each other through iutermediates.
