48 LEPIDOPTERA. 



the collar ; remainder of thorax pale yellow-brown, shoulder- 

 lappets furnished with long loose scales ; abdomen smooth, 

 curled up in some degree behind, yellow-brown, hinder seg- 

 ments tinged with purple ; lateral tufts inconspicuous ; anal 

 tuft dark pui'ple. Fore wings truncate and of very unusual 

 shape ; costa much arched ; apex rectangular ; hind margin 

 below it straight and nearly perpendicular to the middle, 

 then curved in and deeply excavated to the anal angle, which 

 is defined and rather sharp ; dorsal margin straight; colour 

 soft silvery yellowish-brown, almost yellowish-white, much 

 obscured by abundant perpendicular slender tawn}' or purple- 

 brown streaks ; usual markings almost absent, but the second 

 line is suggested by a curved and shaded massing of the 

 tawny streaks, which there are intensified, becoming chocolate- 

 red on the dorsal margin ; beyond this the whole area near 

 the anal angle is tinged and clouded with glossy purple ; a 

 small cloud of this colour also lies at the base of the costa ; 

 cilia extremely short, yellow-brown. Hind wings rather 

 extended and rounded at the apex and adjacent portion of 

 the hind margin, but decidedly hollowed toward the anal 

 angle ; silky whitish-yellow shading into pale golden-brown 

 at the apex and hind margin, except the excavated portion, 

 the space above which is broadly dark purple, barred several 

 times with cloudy-black. Female very similar, rather larger 

 and having simple antennae. 



Underside of the fore wings rich golden-yellow, shading to 

 white on the dorsal margin and to pui-ple at the base and 

 anal angle ; the yellow surface softly barred by perpendicular 

 pale purple lines. Hind wings from the base to the middle 

 yellowish-white, transversely streaked and spotted with 

 yellow-brown ; along the hind margin is a very broad purple 

 band edged inwardly with golden-yellow, and mottled with 

 the same. Body dull purple ; legs yellow shaded with 

 purple. 



Hardly variable, except a little in depth of colour and 

 distinctness of the transverse purple-brown streaks.
