BOARMIDAL—ANJSOFTER YX. 249 



white edgings of the transverse lines visible. In the col- 

 lection of Mr. Robt. Adkin is one of a smooth unicolorous 

 whitish-brown, devoid of markings except towards the ajDex. 

 On the wing from the end of February till April, or even, 

 rarel}", till the beginning of May. 



Larva moderately stout, sides wrinkled ; head rounded ; 

 two minute retractile tubercles on the undersurface of the 

 ninth segment ; head pale green, mouth dark brown ; body 

 pale green ; dorsal line faintly darker ; subdorsal and spira- 

 cular lines distinct, yellowish ; between them is an inter- 

 rupted whitish line ; spiracles black ; ventral tubercles tipped 

 with black. 



Very like that of Cheimatohia bncmata, but larger; it 

 maintains a different attitude, a more open arch, upon its 

 food. (C. Fenn.) 



A variety figured by Mr. Buckler has a series of black 

 spots down the dorsal line, and the spiracles distinctly 

 black. 



1'he pair of ventral tubercles mentioned above is regarded 

 by some writers as a pair of ill-developed feet upon the ninth 

 segment. 



April and May, in more northern localities extending into 

 June ; on hawthorn, blackthorn, oak, beech, hornbeam, ash, 

 privet, rose, Hlac, and cherry ; feeding at night ; remaining 

 upon its food during the day. 



Pupa rather short, moderately stout, the eye-covers rounded 

 and swollen ; antenna-cases conspicuous, faintly cross-barred 

 with small hollows; limb-cases compressed; wing-covers a 

 little swollen, dull, but scarcely in the least sculptured; 

 dorsal and abdominal segments rather swollen and rounded 

 up, smooth and shining ; cremaster hardly noticeable on the 

 much-rounded anal segment, but provided with a fine 

 bristle. In a strong small ovate cocoon of silk and earth, 

 underground.
