132 LIME HAWK-MOTH. 



two central spots are united, and sometimes one of 

 them is wanting. 



The caterpillar feeds on the lime, elm, birch, &c. 

 It is pale-green, with seven oblique whitish stripes 

 on each side bordered anteriorly with red or yellow. 

 The head is smaller than in others of the genus, the 

 body more attenuated in front, and there is a granu- 

 lar protuberance over the anus*. 



The rarest of the three, being found only occa- 

 sionally ; but it seems to be pretty generally distri- 

 buted throughout England. It occurs near London 

 more frequently than in most other places; also 

 near Exeter, York, &c. It does not seem to be a 

 Scotch insect.
