144 T.EPIDOPTERA. 



a sepia coloured clash on the inner side of each lobe ; body 

 dull greenish-brown with an ochreous tinge, sides darker; 

 all the markings but faintly indicated ; usual spots white 

 surrounded Avith grey ; down the back an indistinct grey 

 chain-pattern, each link enclosing a grey spot ; spiracular 

 stripe broad, reddish-ochreous, the sides above it broadly 

 shaded with grey ; spiracles white, edged with black ; under-

 C. Fenn. Mr. Buckler states that the newly-hatched larva 

 has a very pale and transparent pinkish-grey body, a pale 

 brown head, and a blackish-brown dorsal vessel, but after 

 commencing to feed becomes of a light j-ellowish-w^atery- 

 green with minute black dots. After the first moult the 

 colour becomes a more opaque bluish-green, still with the 

 black dots, and with broad paler dorsal and narrower sub- 

 dorsal lines ; the head yellowish-green sprinkled with black 

 atoms; after the second moult a paler spiracular stripe 

 appears, and after the third this stripe becomes greenish- 

 yellow or ochreous-yellow, and the black dots are ringed 

 with whitish-yellow. After the fourth moult the general 

 colour, though deep and of sober richness for a time, 

 gradually grows paler, and three varieties can be noticed 

 — brownish-green, ochreous-green, and light brown, the 

 markings as before. After another moult the adult colouring 

 is assumed.

 its food plants close to the ground, or half buried in the 

 earth. 



Pupa short and rather stout, head and thoracic portion
