in no soiiso a cocoon, in tlie leaves and rnbbish abont the trees, or on 
tilt' trees in the dried and shriveled leaves of the injured shoots, or it 
attaches itself exposed on tlie t\vi«jjs or bark. After thus securing^ itself 
the larva immediately pupates, ])ecominfc a ])rown, rather robust, chry- 
salis (li^^ 2. c, </). in midsummer these transformations are very (piickly 
accomplished. A larva, for example, which webbed up June 29, pupated 
July 1, and the adult emerged July S. 
Mr. Khrhorn states that it is very diflicult to lind the i)upa* in orchards 
as the Iarv;e hide in all sorts of places, as in crotches of the branches, 
between dried leaves, and about small peaches likely to drop ott". 
The chrysalis stage lasts from seven to ten days, and the moths of the 
tirst brood l)egin to appear early in May and continue to emerge through 
out this month and into June in the 
latitude of NA'ashington. 
The adult moth is less than a (piar- 
ter of an inch in length, expanding 
a little more than half an inch, and 
is of a beautiful dark-gray color, 
with darker spots on the forewings, 
as indicated in the illustration 
(fig..'i). It is a handsome insec't and 
has a peculiar way of resting with 
its ])alpi bent back over its head and 
its antenna* laid closely down on 
the wings. The description of the 
insect by Clemens is reproduced : 
A. f pruniella. — Head and face pale <;ray; 
thorax dark f^ray. l.aluial palpi dark fus- 
cous exterually and pale gray at the end; 
terminal Joint jjray, dusted with dark 
fuscous. Antenna* grayish annulated with 
dark brown. Forewings gray, du.sted 
Avith blackish brown. Avith a few blackish brown spots along the oosta, the largest 
in tlu^ middle, and short blackish-brown streaks on the median nervure, subcostal, 
in the fold and one or two at the tip of the wing: cilia fuscous gray. Hind wings 
fuscous gray; cilia gray, tinted with yellowish. (Proc. Acad. Nat. Sc, I'hila., 18G0, 
p. !(>}).) 
The egg-laying habits of this insect up to this time not having been 
discovered and for the fall brood even being merely a mattei of con- 
jecture. s]>ecial effort was made to get the facts concerning this feature 
of the life history. A number of moths reared in the Insectary were 
confined about May 10 with peach twigs eight to ten inches in length, 
of this year's growth. The material was unfortunately not examined 
for too long a time, but on May 2S it was found that many eggs had 
been deposited on these peach twigs, an Qfn:^ having been placed appar- 
ently Just above the base of the petiole of nearly every leaf. When 
examined most of the euiis had hatched and the larva* had entered the
