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 ^'s- '^'^• 



"Prairie Farmer," describes H. phloxiplaiga Grote 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, 

 ^ and becoming moths by the middle of August, 

 the second passing the winter in the chrj^salis 

 state. The eggs are deposited singly on all 

 Fig. 24G. portions of the plant, and the caterpillar, 



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

 terweaves grains of sand with a few silken theads, forming a 

 very slight elastic cocoon." The genus HeUocheilus differs 

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

 Grote (Fig. 246, vena-

 pale testaceous moth,

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
