ioo LEPIDOPTERA. 



rounded behind, uniform dull brown with a purplish flush ; 

 cilia paler. Female extremely similar. 



Underside of fore wings dull smoky-brown ; costal margin 

 narrowly, and hind margin broadly, pale purple-brown ; dorsal 

 margin whitish. Hind wings dull pale, ochreous dusted with 

 brown and having a slender central brown transverse line. 

 Body and legs yellow-brown ; front tibiae white with thick 

 golden-brown tufts of scales on the knees. 



Variable in the colour of the golden bands, as already 

 described, irrespective of sex, from brilliant gold or even 

 brassy gold colour to a rather dull green-gold ; but there is 

 reason to believe that the shade of colour changes during 

 life, from damp or other causes, from the brilliant to the 

 green gold. Except in the separation or junction of the two 

 bands there is little other variation. 



On the wing in July and August, and rarely, as a second 

 generation, in September. But in the year 1896 this second 

 brood was found in plenty in the New Forest, Hants. 



Larva plump, tapering off smaller toward the head ; 

 the anal segment also tapering off suddenly and rather 

 elongated ; head rounded, yellow-green ; body pale green ; 

 dorsal line deeper green, bordered on each side by un- 

 dulating white lines, which from the fifth to the twelfth 

 are swollen and attenuated on every segment, and usually 

 interrupted at the incisions ; on the same segments the 

 lateral surface is occupied by oblique shorter white lines 

 which unite with those on the back, and are margined 

 beneath by a more slender and continuous white line, below 

 which is the spiracular line, also white, broad, and con- 

 tinuous from the second to the tip of the anal segment ; on 

 the second to fourth and the anal segment the white lines 

 are fewer and placed longitudinally ; legs and prolegs green, 

 the anal pair rather extended ; undersurface green with 

 minute white dots. 



August to May, and sometimes a second generation in
