are sometimes visible, are of a dull 
brown, and with no distinctive features. 
The silk tubes are quite eonspicuous ; 
mouth-parts dark. 
The anterior segments are longer 
than the others, and the large, strong, 
clawed feet seem to spring from the 
middle line of the venter, making a 
semicircle terminated by the claws. 
When the larva is resting in the day 
these claws are all bunched up, at the 
mouth of the case, or withdrawn within 
it, only one remaining attached to the 
branch from which it is thus momentarily 
suspended. 
At night the larva spins a number of 
threads from the case around the branch, 
and retires within its recesses. Ordina- 
rily the mouth of the case, large and 
loose, falls together when not expanded 
by the larva’s body. For the pupal 
change, it spins up the mouth and fixes 
it firmly to some stationary object, 
usually its food-plant. 
If the case of one of these larvae be 
cut open, and an empty one be cut and 
applied to it, the larva, although pre- 
paring to enter the pupa stage, will rouse 
itself and unite these into one. The 
larvae also use for the construction of 
these cases various kinds of leaves, 
twigs, and vines. These are put on, one 
over the other, like shingles on a house, 
and frequently so near together that they 
stand out straight and look ruffled. 
A larva having been removed from its 
case and put in a pill-box, with some 
raw cotton and its proper food, soon con- 
structed for itself a new case from the 
cotton, lined it with silk, made a mouth 
for it, and then, crawling to a branch 
placed near, suspended itself as usual. 
In order to remove it from its natural 
case I had only to touch this on one end, 
and the larva would continue retreating 
until it emerged at the opposite extrem- 
ity. After many interesting exploits 
this larva disappeared. 
HABITS OF HYPOPREPIA PACKARDIT, GROTE. 
BY MARY ESTHER MURTFELDT, KIRKWOOD, MO. 
In 1879 I had the pleasure of tracing 
the larval history of the pretty little 
Lithosian above named, the imago of 
which was described some years ago by 
Mr. A. R. Grote in the Proceedings of 
the Entomological Society of Philadel- 
phia, April, 1863, v. 2, p. 31. 
Upon my writing to Mr. Grote regard- 
ing its immature stages, he informed me 
that nothing had been published on the 
subject, and that he himself had never 
observed the transformations. As I have 
seen nothing since that date referring to 
this species, I trust that the following 
notes may not be altogether without in- 
terest to those making a specialty of the 
group to which it belongs. 
Two larvae were found in dormant 
state, 20 Dec., under loose bark of black 
oak (Quercus tinctoria Bart.). They 
were then about 6 mm. in length, hairy, 
and of a mottled light and dark gray 
color, the head being similarly clothed 
and colored. They bore a strong gen-
