It feeds exposed on low plants, preferring the flowers. The 



pupa is conical and subterranean. H. armigera Linn. (Fig. 



244; a, larva) is the "boll 



worm" of the Southern States, 



so destructive to cotton crops. 



Riley states that it also feeds 



on the fruit of the tomato, and 



in Southern Illinois on the silk 



and green kernels of corn and 



also the phlox, tomato and 



corn-stalks, and, according to 



Mr. T. Glover, it bores into the 



pumpkin. Mr. Riley, in the 



Fig. 244. 



"Prairie Farmer," describes apparently the same insect under 

 the name of the ' ' Phlox worm " (Fig. 245 , and larva) . He states 

 that there are two broods in a year, the first appearing in July, 

 2=:^ and becoming moths by the middle of August, 

 z£v'^ the second passing the winter in the chrysalis 

 state. The eggs are deposited singly on all 

 246. portions of the plant, and the caterpillar, 



when about to become a chrysalis, enters the ground, and in- 

 terweaves gi'ains of sand with a few silken theads, forming a 

 very slight elastic cocoon." The genus HeliocheUus differs 

 from Heliothis in its broader and shorter wings and its vena- 

 tion. H. paradoxus 

 Grote (Fig. 246, vena- 

 tion of fore wing) is a 

 pale testaceous moth, 

 with the fore wings i 

 darker. It inhabits ^ 

 Colorado Territory. 



Anarta is rather a 

 small moth, with a 

 hairy body and small 

 head ; the fore wings Fig. 245. 



are thick and velvety, with confused markings, and the hind 

 wings are yellow or white, often bordered with black. The 

 larva is short and smooth in repose, with the anterior portion 

 of the body bent under the breast. The pupa is enclosed in a
