Fig. 166. — Caterpillar of White-lined Sphinx — colors, green 

 and yellow. 



This worm appears in two entirely different colorings; 

 in the more common form (Fig. 166) it is yellowish-green, 

 with a row of oval spots along each side of the back, which 

 are usually connected by a yellow line ; these spots consist of 

 two curved black spots enclosing a yellow and a crimson spot.

Fig. 167.— Caterpillar of White-lined Sphinx— colors, black 

 and yellow. 



In the other form (Fig. 167) the body is black, usually 

 marked on the back with a yellow line, and with a number of 

 yellow spots on each side of the body. When fully grown it 

 measures from three to four inches in length ; it then creeps 

 beneath some leaves or other rubbish, sometimes even enter- 

 ing the earth, and forms a smooth cell in which to undergo 

 its transformations. 



The fore-wings of the moth (Fig. 168) expand about three 

 inches, are of a dark olive-green color, with a whitish line 

 extending from the base to the tip of each wing ; the hind 

 wings are black, with a rose-colored band extending length- 

 wise through the middle. This moth is quite common in this 

 State, and may frequently be seen in the evening twilight 

 hovering over the flowers like a humming-bird.
