CERURA. 243 



_ When about to pupate it forms a firm, narrow cocoon, with 

 fragments of bark, spHnters, or moss. It is oval, and the 

 threads are white. 



The pupa is reddish-brown, and very small in comparison to 

 the larva.

Cerura includes several species with white, rather thinly- 

 scaled, wmgs, with dark transverse or zig-zag markings, stout 

 woolly bodies, extending beyond the hind-wings, antennae pec- 

 tmated m both sexes, and two small terminal spurs on the hind 

 tibice. The largest, and also the commonest, of our British 

 species IS called the "Puss-Moth," and the smaller species are 

 known as the "Kittens." ^The larv^ are green, varied with 

 purphsh-brown, truncate in front, with an elevation on the 

 third segment, and the anal claspers modified into long processes 

 enclosing retractile filaments. The pupa is enclosed in a hard 

 cocoon. The species are rather numerous in the Northern 

 Hemispliere.
