Larva known as the Tomato or Potato Worm ; has been so often described that it 

 must be familiar to most : 



It measures about three inches in length, is smooth and wrinkled transversely ; head 

 green, small and shining, with a black stripe on each side ; the breathing pores black, 

 except the two last, which are yellow ; the usual colour bright green marked with white, 

 with seven straight oblique greenish-yellow stripes; body dotted with numerous greenish- 

 yellow spots. 



Caudal horn long, slightly curved backward and granulated ; variations of colour are 

 very great ; common colour is leek-green, from this it varies to lighter green, and to 

 various shades of darker brownish and blackish green ; in other instances the green wholly 

 vanishes and the worm is pale or deep amber-brown, blackish-brown, purplish-black or 

 pure black ; a voracious feeder and does much damage to the tomatoes and potatoes. 



Pupa is a bright glossy chestnut colour, with a long and slender tongue case bent over 

 from the head so as to touch the breast only at the end, and somewhat resembling the 

 handle of a pitcher. 



The 3foth expands about five and a half inches, is of a grey colour, variegated with 

 blackish lines and bands ; on each side of the body are five round orange -coloured spots 

 encircled with black. Its tongue when unrolled is nearly six inches long, but when not 

 in use is concealed, like that of all the Sphingidae, between the palpi, coiled like a 

 watch-spring.
