era1 resemblauce to the young larvae of
some species of Calliw,orp?m.
Fearing that they might succumb to
the somewhat unnatural conditions of
the rearing cage, I attached them, for
hibernation, to a branch of the tree,
under a thick muslin cover. They were
not again examined natil the middle of
the following March, when, as the season was early, they were found to have
awakened from their torpor and to be
crawling about over the bits of bark upon which they- had wintered. For more
convenient observation they were again
placed in the insect cage and liberally
supplied with the roost advanced buds.
They did not, however, seem to i'eed
upon the latter, and continued to crawl
about restlessly over the bits of dry bark, which, they covered with a great deal
of fine cobwebby matter. On the 1st
of April both molted and shortly after
this I discovered that they fed upon the outer surface of the bark itself, or upon the lichens thnt covered it. Fresh bark
was provided upon which they began
gnawing with avidity and from this time
growth was quite rapid. A second molt
occurred 15 April and a third 1 May. At
this date they measured 8.3 mm. is
length by 2.5 mm. in diameter. The
form was somewhat flattened and the
width nearly the same fhr~~@out. Color
pale cinereous, variegated with fine
curved lines and dots of purple-brown;
medic-doreal stripe pale, margined on
each ~ide with a distinct purple line, not continuona, but composed of very minute
dashes and dots. Venter translucent,
dingy buff. Head and legs colored aim-
ilarly to the dorsiim, all sparsely clothed with long, fine, light hairs springiug di- rectly from the surface.
On 7 May both larvae were enclosed
nuder a veil-like smoke-colored web,
closely appressed to the under side of the bark. They had ~hrunken somewhat and
the thwack segments appeared slightly
flattened and bulging laterally, giving
the insects the appearance of minute
catocalid larvae. By 10 May both had
completed their first transfonmtion.
Pupae, 6.2 mm. in length, oblong, dc-
pressed and of a glossy dark brown
color. The imagines appeared ou 27
and 28 May and proved to be of different sexes.
As Mr. Grote'a description of the per-
fect insect is brief I take the liberty of appending it : -
Imago : "Anterior wings entire, silky,
dark steel grey with a yellowish wen
defined #pot on the costa near the
apex. A band of same color on the
internal marffia, well defined and mm-
inenciug near the internal angle and con- tinning to the base of the wing, showing a spot of the same shade as the ground
colw. Posterior wings rose color with
a wide grqish border not extending
quite to the anal angle. Under side of
the wings showing the markings of the
upper. Head rose color. Antennae
darkish. Thorax yellowish. Abdomen
rose c-olor. Expands eleven sixteenths
of an inch [17.5 mm] .'* In the male the yellow bands and spots on the anterior
wings arc broader than on the female,
and the abdomen of the former termin-
ates in a dense rose colored tuft.
