summer. The generations are not distinct, although at some times 
the moths appear to average fresher than at others. It is very evident 
that they breed continuously and that the larvae do not have any con¬ 
siderable resting period after completing their growth but pupate at 
once. Judging from laboratory rearing records, there are probably 
three generations during the year in Tennessee. Farther north this 
number may be lessened and at the southern limit of its range there are 
probably more. With a species such as this, in which the generations 
follow one another without intermission other than the delays due to 
unfavorable weather conditions, the number of generations in any given 
season is directly dependent on the length of the growing season and may 
vary from year to year. 
All the available data as to the seasonal appearance of moths in other 
regions are so scattered and fragmentary that it seems impossible to 
draw any definite conclusions from them. In the list given under 
“Geographical distribution, “ the seasonal records are arranged by 
States. In the following list the same data are arranged by months, 
in order to show very incompletely the seasonal trend of the occurrence 
of the moths.

THE MOTH 
The writer has never found the moths of this species really abundant. 
Usually they have been taken very sparingly, one or two at a time and 
very seldom as many as half a dozen in a day’s collecting. They were 
seen most abundantly at Greenwood, Miss., on the night of June 22, 
1915, when 34 were taken at electric street lights between 8 and ii p. m. 
In the field the moths seem to prefer more or less open, weedy or waste 
ground, such as neglected strawberry beds or fallow fields, rather than 
grassy places. 
When the moths are flushed during the day, they usually fly only a 
short distance and may be readily captured with a small vial, but toward 
dusk they are much more wary, and when disturbed frequently fly 50 
feet or more before settling. They alight, apparently without preference, 
on any part of an object, leaf, grass stem, or very frequently on the bare 
ground. They seldom rearrange their position after alighting. In the 
field, the silvery stripe and the brassy shade of the forewing in fresh 
specimens make them easy to identify at a considerable distance. Around 
lights at night they can be distinguished from Cranibus teterrellus Zincken, 
the only other species of equal size with which they are apt to be asso-
