margins ; and in the cabinet of the late Mr. F. Bond is a 

 specimen having a black spot at the base of the fore wings. 

 On the wing in May and June. 



Larva cylindrical, but the head a little narrower and rather 

 flattened ; pale green, with an orange-red spot, bordered with 

 black, upon each lobe ; body smooth and soft in texture, bright 

 green, with a row of red or orange-red spots down the back, 

 each of which is bordered with rich brown ; these are separated 

 on the middle segments, but joined together on the anterior 

 and hinder ; the back is faintly dotted with greenish-white, 

 and the sides with black, the spiracles being brown ; under- 

 surface and legs pale green. Before full growth the red spots 

 are absent, the space being occupied by a broad yellow dorsal 

 line ; but the infant larva is wholly deep yellow. The Rev. 

 J. Hellins says " the only variety of the larva that I ever saw 

 was of a pale bluish-green ground colour, the sides and 

 ventral surface being more of a whitish-green ; the bright red 

 dorsal spots of the type were replaced by a very indistinct, 

 interrupted, reddish-brown line, and on either side of this 

 there was, on each segment, a whitish dot, while the usual 

 red spots on each side of the head were absent." This larva 

 was figured by Mr. Buckler, and reared. 



End of June and July, sometimes August, on blackthorn, 

 bird-cherry, and plum ; but abroad, also on rose, willow, 

 birch, and oak. Mr. Hellins states that the egg is laid in 

 crevices of the bark, or at the axils of the shoots, of the food 

 plant, and that if not furnished with these, the moths will lay 

 few, if any, eggs. 



Pupa apparently not described. In this stage through the 

 winter. 



The moth hides during the day among undergrowth in 

 woods, or in hedges in wooded districts, and flies at early 

 dusk along the lanes, rides and open portions, with a very 

 soft gentle movement. It seems more particularly attached
