CERURA. 247 



The larva is yellowish green, dotted here and there with 

 reddish and dark green. The cervical and dorsal spots are 

 connected, and are usually violet, spotted with red and yellow. 

 The former is pyramidal, ending in a blunt cone, and margined 

 with yellow. The dorsal spot is very variable, and is some- 

 times of a rich rosy red. It has a darker central line, and is 

 shaded with darker, especially on the sides of the seventh and 



Larva of Sallow Kitten, 



eighth segments, where it is excavated, and the yellow margin is 

 interrupted. A few small black spots may be seen in front of 

 it on the seventh and eleventh segments. The caudal fila- 

 ments are ringed with yellow and brown. It feeds on sallow. 



The pupa is light brown with greenish wing-cases, and the 

 cocoon is made with chips of wood. 



This is a much commoner species in England than the last, 

 which it greatly resembles.
