of a pinkish tinge, and the darker portions of the wings are 

 brownish, inchning to olive ; sometimes the general colour is 

 ochreous brown with dark brown cross lines, and a rust- 

 coloured lunule at the tips of the fore wings. The hybrid 

 resulting from a female of this species that had paired with 

 a male bilunaria has been named parvihinaria, Bastel. At 

 the time it is laid, the egg is pale olive green, but it changes 

 to shining reddish, and just before hatching to purplish black. 

 (Plate 113, Fig. la.) 



The caterpillar is reddish brown, mottled with darker brown, 

 and with pale greyish. It feeds on birch, alder, oak, sallow, 

 cherry, etc. : June and July, and again in the autumn. (Plate 

 113, Fig. I.) 



The moth is out in April and May, and the second 

 generation emerges in July and August. A few specimens 

 of a third generation have been reared in October, but this 

 is unusual. 



The species is more or less local, and rarely common, at 

 least in the moth state ; it occurs in all the southern counties 

 of England, and a few specimens have been recorded from 

 some of the midland and northern counties, and from South 

 Wales. In Scotland, only noted from Rannoch, Perthshire, 

 and a specimen was reared on April 25, 1901, from a cater- 

 pillar found at Dunkeld, in the same county, the previous 

 autumn. 



Abroad, the range extends to Amurland and Japan. 



Lilac Beauty {Hygrochroa {Pericaiiia) syringaria). 



The sexes of this species are shown on Plate 112, and it will 

 be noted that the male (Fig. 7) is rather smaller and decidedly 

 more brightly coloured than the female (Fig. 8). An older 

 English name is " Richmond Beauty," Wilkes. Figures of the 

 curiously shaped caterpillar and chrysalis will be found on Plate
