The larvae mine leaves of several species of poplar — in Ohio 
leaves of cottonwood (Popuhis deltoides). The mine (Fig. 8) 
is indiscriminately placed on the upper or the lower side of the 
leaf. It is a whitish, gradually broadening linear track, 2 or 
2.5 mm. broad at its extremity, with a black line of frass. Cocoon 
ochraceous. In the latitude of Cincinnati there are several 
generations a year; mines containing larvae may be found in 
June, in the latter part of July, and in September. 
This species differs from the preceding in the absence of the
