as the wings ; the antennae reddish internally, and 

 yellowish- white on the outer side. 



The caterpillar bears much resemblance to that 

 already described, being usually green, with oblique 

 yellow or white stripes. The stigmata are yellow 

 or rose-colour, with a white centre ; the membran- 

 ous legs often ornamented with a curved orange 

 spot externally. The head is bordered with yellow, 

 and the anal horn is of that colour, with the base 

 blue. It eats the leaves of poplars and willows.

 common of the Sphingidae, being frequent in all 

 parts of England, and generally distributed over the 

 southern division of Scotland. It is found about 

 midsummer and in autumn.
