OLEANDER HAWK -MOTH. 157 



The under wings are dusky from the base nearly to 

 the middle, and green on the hinder border, the 

 two colours separated by a white waved band, 

 extending from the anal angle to the anterior edge. 

 The thorax is deep green, with a pale cross line in 

 front ; the abdomen likewise green, whitish on the 

 first and second segments, and having oblique olive- 

 coloured streaks on the sides of the others. 



When the caterpillar is full grown, it is green 01 

 greyish-green, with the four anterior segments pale 

 yellow ; a white line along each side, extending from 

 the fourth segment to the anal horn and numerous 

 white dots scattered over the surface. On each 

 side of the third segment there is a large blue eye- 

 shaped spot with a double white pupil and a black 

 iris. The anal horn, which is short and decumbent, 

 is ochreous ; the anterior legs blue ; and the mem- 

 branous ones green with the extremity yellow. The 

 head is green, the stigmata black bordered with 

 yellow. When immature the colour of this cater- 

 pillar is sometimes a pretty uniform ochreous yellow, 

 and in all cases, a few days before it becomes a 

 pupa, the four anterior segments and the anal one 

 assume the colour just mentioned, while the re- 

 maining parts of the body become dusky black, the 

 white lateral line, dots, and ocellated spots always, 

 however, remaining unchanged. Its appropriate 

 food is the leaves of the shrub named Nerium 

 oleander^ nor has it recourse to any other when that 

 can be obtained. As that plant, however, is not a 

 native of this country, nor of the north of Germany
