DELTOIDES. 279 



legs ten in number, but the first two pairs very short and 

 apparently not used in walking, and the anal pair the largest ; 

 of the colour of the body, but a black streak runs down the 

 front of the fourth pair. (W. Buckler.) 



September till May on the lichens which grow upon old 

 hawthorns, blackthorns, crab and apple trees, cherry, larch, 

 spruce, and yew, probably upon almost any tree lichens, 

 feeding at night, remaining closely at rest upon the lichen 

 during the day. Mr. Buckler urges its very close agreement 

 with the larvae of Catocala in the fleshy filaments on its sides, 

 in its manner of walking and of resting. 



Pupa of the Noctua form, rather slender, the mouth forming 

 a rounded projecting knob ; limb and wing covers extremely 

 smooth and apparently without sculpture, but not very glossy, 

 the head portion most so ; segments excessively channelled 

 or wrinkled in incised lines round their circumference, but 

 the hinder edges smooth and prominent, also pale drab, the 

 rest of the segments being red-brown and the wing and limb 

 covers pitchy-brown ; cremaster short, conical, smooth, dark 

 brown, furnished with a tiny bunch of curled bristles. In a 

 yellowish-white cocoon of tough silk, placed within a drawn- 

 together leaf. 



The moth is apparently rather inactive. It sits in the day- 

 time in trees of any thick growth, or on which lichens are 

 abundant, such as oaks, thorns, crab-trees, yew, larch and 

 other firs, or even in large thick hedges, and when beaten or 

 shaken out flutters lazily down into some other concealment, 

 or on to the ground ; doubtless it flies at night, but seems 

 rarely or never to be captured at that season, and not to be 

 attracted by flowers or other sweets, and hardly by light. 

 Local and uncommon in this country, but found occasionally 

 at Haslemere, Boxhill, Gomshall, and elsewhere in Surrey ; 

 in various localities in Kent and Sussex ; in the New Forest, 

 Woolmer Forest, and Bournemouth, Hants ; in the woody 

 heaths of Dorset, Wilts, and Berks ; in Middlesex, Essex,
