2Qo LEP1D0PTERA. 



gracefully curved transverse brown line is continuous through 

 the middle of each. Body and legs yellow-brown. 



Not variable. 



On the wing at the end of June and in July. 



Larva nearly three-quarters of an inch in length, thick in 

 proportiou, cylindrical and tolerably uniform in bulk, though 

 the two or three hinder segments appear the stoutest, par- 

 ticularly when it is walking ; the thirteenth segment is 

 tapered behind, and beneath its extremity the small anal 

 pair of prolegs come very close together ; the ventral prolegs 

 are short and much beneath the body, the legs also small ; 

 head globular, velvety, brown ; skin soft, smooth and 

 velvety, dark brown covered with an exceedingly fine and 

 short pubescence resembling the pile of fine silk velvet, this 

 where the light reflects appears of a pearly whiteness ; there 

 is a faint indication of a darker dorsal line and a still fainter 

 suggestion of a subdorsal line ; raised dots black but only 

 just discernible ; spiracles of the ground colour, ringed with 

 black, and beneath them the ground colour is of a paler 

 brown than the back ; a narrow plate of rather darker brown 

 across the middle of the second segment is divided on the 

 back by a thin line of the ground colour. 



The newly-hatched young larva is about one-sixteenth of 

 an inch long, and has a large pale brown head ; the body 

 whitish and pellucid ; its internal broad vessel of dark brown 

 shows through the skin to the full width of the thoracic 

 segments, and thence tapers to a blunt point within the 

 tenth ; the usual raised dots are blackish and shining, and 

 each bears a long pale hair. Soon the dorsal plate begins to 

 appear, and when it attains the length of a quarter of an 

 inch the skin becomes opaque, rusty-brown, closely resembling 

 the dead leaves on which it feeds, and thus it remains through 

 hibernation till May, when the adult colour is assumed. It 

 hibernates in a little nook or corner of a dead leaf, formed 

 by turning down the edge and securing it by three or four
