190 INSECTS INFESTING THE GRAPE. 



The full grown caterpillar (Fig. 175(f) measure.^ about six 

 lines in length, is of a pale yellow, with a row of l>lack prickly 

 tufts on each segment ; the first segment is black, with a yel- 

 low edge, and the head is brow'n. When about to pupate they 

 desert the plants and spin in some sheltered place their tough, 

 flattened, whitish cocoons (Fig. 175r). The perfect moth (Fig. 

 175, d and c,) expands a little under an inch, and is wholly 

 black except the deep orange collar. I have not found this 

 species in this State, although its presence here has been 

 reported. The above description is taken from Riley's Second 



Missouri Report.
