LIPARID/E. 293 



snow-white scales which overhang the base of the abdomen ; 

 its remaining portion being dark brown, with a spreading 

 dark golden-brown anal tuft. Fore wings broad, somewhat 

 triangular, with the costal and dorsal margins nearly straight, 

 apex rounded, hind margin rounded and oblique ; dull silky 

 white, with a thickly-scaled glistening appearance in a cross 

 light, and with a very faint tinge of brownish towards the 

 costal margin, which tinge, in preserved specimens, gradually 

 increases and extends to the nervures ; usually spotless. A 

 fringe of long white scales on the dorsal margin stands up 

 over the back when the wings are closed ; hind wings ample, 

 round, spotless, dull silky white; cilia all white. Female 

 similar, but having upon the short antennae distinct though 

 short pectinations ; abdomen stout and cylindrical with a still 

 larger rounded anal tuft or bunch of dense golden-brown 

 scales. Underside of all the wings snowy white, in the 

 males with a smoky black stripe along the costa ; body rather 

 silvery white except the brown apical tuft ; legs whitish with 

 long tufts of pure white scales. 



Variation very slight, but occasionally a small black dot is 

 visible at the apex of the discal cell of the fore wings, and 

 two or three short blackish streaks near the anal angle. In 

 the collections of the late Messrs. Doubleday and Bond are 

 specimens having three black dots placed triangularly at the 

 apex of the discal cell ; Mr. S. Webb has some with the short 

 black streaks at the anal angle, and above them other very 

 small dots parallel with the hind margin, indicating a normal 

 second line, and Mr. 0. A. Briggs has specimens having both 

 the discal dots and the dotted indications of the second line, 

 the dots placed singly or in pairs. Other specimens are 

 known having the base and margins rather brownish. 



On the wing at the end of June and in July. 



Larva one inch and a half long ; nearly cylindrical but 

 slightly tapering at the extremities ; head narrowed and 

 rather long, with the lobes pointed in front, grey, with a
