28o LEPIDOPTERA. 



spicuously darker ; subdorsal lines whitish ; spiracular lines 

 pink ; anal points margined with white ; undersurface pro- 

 vided with three distinct white lines, a])proximating at the 

 base of the third pair of legs, to which point the spiracular 

 line emits a branch. (C. Fenn.) But often the points on 

 the head and second segment are pink, the spiracular line 

 has become a broad pale pink stripe, and the anal points are 

 of the same colour, 



August till June, on broom, furze, and petty-whin {Genista 

 anglica), feeding at night. In the daytime it remains upon 

 its food-plant, its legs folded close to, and almost concealed 

 under, the anterior segments, the points of the latter, with 

 its stiff attitude, giving it a singular resemblance to a small 

 twig. It hybemates, while quite small, upon the stem of its 

 food, in a perfectly rigid posture, half erect, and showing the 

 most perfect indifference to weather, even the severest frost. 

 In confinement it is easily induced to eat the leaves of 

 Laburnum. 



Pupa smooth, slightly elongated ; hooked at the anal 

 extremity ; very pale green, shaded with ochreous and pink ; 

 the whole surface covered distinctly with small black dots ; 

 antenna-cases marked with converging black dots ; dorsal 

 line darker green ; anal extremity reddish. In a slight 

 cocoon formed of a few silken threads between the drawn- 

 together twigs and leaves of its food-plant, between which it 

 is quite visible, and from among which it is easily dislodged. 

 (C. Fenn.) 



The moth sits during the day among the twigs of furze 

 and broom, or sometimes conspicuously upon the bushes, 

 when it may readily be boxed. When beaten out it flies 

 vigorously to a similar hiding-place at no great distance. Its 

 natural flight is at dusk and in the night. Common upon 

 heaths, moors, and commons, or even open woodlands, where 

 its food-plants grow, throughout the Southern, Eastern, and 

 Western Counties of England ; very scarce in the Midlands,
