GEOGRAPHICAL DISTRIBUTION 
Crambus praefectellus is a strictly American species and seems to be 
limited to the eastern half of the United States. It has been taken in 
practically every State east of the Mississippi River and also in North 
Dakota, South Dakota, Minnesota, Iowa, Colorado, Missouri, Arkansas, 
and eastern Texas. It is reported from Cartwright, Manitoba, and also 
occurs in eastern Canada, at least along the southern edge. The ac¬ 
companying map (Fig. i) shows at a glance its present known distribu¬ 
tion. The following list gives the States from which records are avail-
