is worthy of note on account of its past records elsewhere. It has 

 been found commonly in northern Texas feeding on cotton foliage 

 and eating into the squares. 

 The different stages are shown 

 in ligure 13. It is readily con- 

 trolled 1)}^ means of arsenicals. 



The fall army worm (Za- 

 phyg ma frag Iperda S. & A.). — 

 Occasionally the larvte of the 

 fall army worm stray into the 

 cotton fields when they become 

 excessively al^undant — in late 

 summer or earh^ fall — and 

 sometimes do local injur}^ to 

 the foliage. 



The lo moth {Aatomeris to 

 Fab.). — The green, spine-cov-

The cotton-boll cutworm {Prodema ornithogaUl Guen.) (figs. 11 and 

 16). — Throughout the season the caterpillars of this so-called cutworm

are found eating the foliage and boring into the squares and bolls 

 much as does the boUworm. But in habits the}^ are quite different 

 from the true cutworms, feeding by day and not cutting off' the stems 

 of the young plants. The olive or greenish-brown caterpillars may
