154 CATERPILLARS AND THEIR MOTHS 



what distended look about the abdominal segments. 

 The thoracic segments were bent forward and down- 

 ward, so that the flat " face " of the head lay on the 

 ground. Two brown dashes appeared on the third 

 segment, one on each side of the dorsal line, and on 

 the front edge of each side of the eighth, ninth, and 

 tenth segments, near the spiracles, appeared a similar 

 but paler dash. The body was constricted between 

 the abdominal segments. The head, body, and horn 

 were of a pale, dirty green, and all the markings of 

 the caterpillar had vanished, the skin looking dry and 

 detached between the abdominal segments. At inter- 

 vals shivers ran through the body, as if it felt a sharp 

 and sudden pain. 



Next there appeared on the dorsum of each abdomi- 

 nal segment a brown band, which, when examined 

 with a lens, was made up of small brown punctures 

 set close together. 



Next the skin wrinkled on the eighth and ninth 

 segments, still more on the tenth, and grew whiter 

 between them. The seventh, eighth, ninth, and 

 tenth segments became distended still more, and 

 the skin grew white on the sides like a slight water- 

 blister. 



At this point the first five segments were bent to 

 one side a little. The skin grew more wrinkled and 

 detached-looking, though no perceptible motion of the 

 pupa wrinkled it. A white dorsal line appeared on 

 the first segm,ent and extended to the dashes on the 

 third, though not immediately. Three hours had 

 passed while the larva was watched, if it can be called 

 a larva, since really it was the pupa in the larva-skin.
