Ashmead" records an ant, Monomorkun carhonariurn Smith, as feed- 
ing on the l^oll worm, and the same ant was again seen at Victoria feeding 
on emlnyo bollworms extracted from their shells. The same observer 
found Sole)iopsis geminata Fab. eating boUworm eggs, and we have seen

a second, smaller species of the genus {Solenopsis texcma Em.) very 
common on young cotton plants and apparently destro3nng newly 
hatched larvae which had been placed there pur- 
poselv. Other ants have been observed under 
more or less suspicious circumstances which point 
to them as possible bollworm destroyers, although, 
on the whole, their value in an economic way is 
very doubtful. Following is a list of the ants in 
the probable order of their importance: 
1. Solenopsis geminata Fab. 
2. Cremastog aster lineolata Say. 
3. Solenopsis texana Emery. 
4. Monomorium carhonariurn Smith. 
5. Dorymyrmex pyramicus Smith. 
6. ForeUus maccooki Emery. 
A worker belonging to the first of these species 
is shown in figure 15. 
The larvee of certain species of Chr3^sopa (fig. 16) are often abun- 
dant on corn and cotton plants, feeding on both the young larvae and 
the egg^. The eggs of the chrysopa are laid on the cotton plants 
quite frequently and are sometimes mistaken for the eggs of the boll- 
worm. They are deposited in an entirel}^ different manner, however 
(see fig. 16, (/), being attached by a long flexible stalk and not laid fiat 
upon the plant, as is the case with those of the bollworm. 
On two occasions, once at Clarksville, Tex. , and again at Victoria, 
during May, 1903, a small reddish mite was seen feeding on freshly laid 
bollworm eggs.
