in no sense a cocoon, in the leaves and rubbish about the trees, or on 
the trees in the dried and shriveled leaves of the injured shoots, or it 
attaches itself exposed on the twigs or bark. After thus securing itself 
the larva immediately pupates, becoming a brown, rather robust, chry- 
salis (fig. 2,c,d). In midsummer these transformations are very quickly 
accomplished. <A larva, for example, which webbed up June 29, pupated 
July 1, and the adult emerged July 8. 
Mr. Ehrhorn states that it is very difficult to find the pupe in orchards 
as the larvee hide in all sorts of places, as in crotches of the branches, 
between dried leaves, and about small peaches likely to drop off. 
The chrysalis stage lasts from seven to ten days, and the moths of the 
first brood begin to appear early in May and continue to emerge through- 
out this month and into June in the 
latitude of Washington. 
The adult moth is less than a quar- 
ter of an inch in length, expanding

has a peculiar way of resting with 
its palpi bent back over its head and 
its antenn laid closely down on 
the wings. The description of the 
insect by Clemens is reproduced :

The egg-laying habits of this insect up to this time not having been 
discovered and for the fall brood even being merely a matter of con- 
jecture, special 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 28 it was found that many eggs had 
been deposited on these peach twigs, an egg having been placed appar- 
ently just above the base of the petiole of nearly every leaf. When 
examined most of the eggs had hatched and the larve had entered the
