“Many pupe were found naked on the surface of the soil, and 
others in a slight silken web just beneath the surface of the 
soil.” The majority of the pupz are probably formed late in 
June. 
The odult.—The adults appear during the last days in June or 
early in July. Most of those under our observation emerged 
during the first ten days of July. They are small active moths 
that fly toward dusk or at night, hiding during the day in any 
convenient retreat. They measure about three-eighth inch in 
length and about one-half inch from tip to tip of the expanded 
wings. They rest with the anterior part of the body well up. 
The color is slate or ash gray, often with a brownish tinge. 
The fore wings are marked with small dark spots. Four larger 
ones are readily distinguished near the middle and sometimes 
one near the base. A dark patch or broad line marks the tip 
which is also bordered with small black dots. These dots may 
extend along the anterior and posterior margins, either one or 
both. The posterior wings are dusky colored with a steel blue, 
or as Slingerland™” has described it, an azure blue reflection. 
They are heavily fringed. (Plate XX VI, Fig. 6; and Fig. 7, 
middle figure.) The joints of the antenne are alternately dark 
and light. Plate XX VI, Fig. 4, shows a moth natural size with 
wings expanded. 
The variations in the markings of both larve and adults have 
resulted in the same species being described under different 
names.4 Fitch?’ describes six varieties based on the markings 
of the wings. Three variations from the typical form (Plate 
XXVI, Fig. 6) are shown at Fig. 7. The two lower wings do 
not seem to come under any of Fitch’s varieties, but the lower 
one was supposed by him to belong to a distinct species. Slin- 
gerland* retains this as a variety. 
From the published accounts of this species it appears that 
the life of the adult is not yet well understood. It seems prob- 
able, however, that the species hibernates in the adult stage.
