areas should very greatly reduce their numbers and if this is attended 
to before or soon after the appearance of wheat above the ground 
the attacks on this crop should be largely prevented.

The species DrsecuZacepliala mollipes (fig. 4) was described b} r Say 
in 1831 among the early descriptions of American insects and has 
been a very commonly observed species ever since. Nevertheless 
it seems to have received much less notice from the economic stand-

insects in 1851, but without economic discussion; in 1884 Uhler gave 
a description in the Standard Natural History, saying that "the 
salt marshes of the Atlantic States furnish places of shelter for it 
where it may be found on weedy grasses in all stages from June to 
October." In 1890 Prof. H. Garman, in the Second Annual Report 
of the Kentucky Agricultural Experiment Station, describes it as a 
corn pest and speaks of it as abundant in several stages of growth

stages, as he says that the recently matured specimens predominated
