lines narrow, yellow ; there is also a faint dotted white line 

 between the subdorsal and spiracnlar; spiracles indistinct, 

 white encircled with black ; legs green, tipped with shining 

 black; undersurface and prolegs of a uniform dull green. 

 (G. T. Porritt.) 



May to July on oak, sallow, ash, lime, birch, apple, 

 bramble, plum, and lilac, and often as it gets towards full 

 growth it leaves the trees to feed upon low-growing plants. 

 If not supplied at this time with sufficiently succulent food, 

 in confinement, it falls upon and devours other individuals of 

 its own species. 



Pupa smooth, shining brown, with two diverging spikes 

 on its tail. In a close earthen cocoon. Not more fully 

 described. 



It is uncertain where the moth hides in the daytime in 

 autumn ; in the spring, after hybernation, I have found it 

 sitting upon a tree-trunk, and also hiding under thatch on 

 outhouses. At dusk it comes readily in the autumn to ivy- 

 bloom, sugar, ripe blackberries, yew-berries, and even rotten 

 apples, and in the spring to sallow-bloom. Sometimes at 

 this season it becomes extremely bleached ; yet it is not 

 until the spring that it pairs and deposits its eggs. Not by 

 any means so scarce as the last species, yet hardly so widely 

 distributed, since it seems to be quite absent from the East 

 of England. It has, however, been taken in Middlesex and 

 Surrey, also in Sussex, the Isle of Wight, and Dorset ; rarely 

 in Cornwall ; more frequently in Devon, Somerset, Glouces- 

 tershire, Herefordshire, and Worcestershire ; rarely in Cam- 

 bridgeshire and even in Cumberland, and there is a single 

 record of a specimen near Liverpool. It must, I think, be 

 frequent in Wales, since I found it far from rarely in 

 Pembrokeshire, and have no doubt that the X. semibrunnea 

 recorded as common at Langharne, Carmarthenshire, was 

 really this species. I know of no instance of its occurrence 

 in Scotland, but in Ireland it has a wide range, having been
