The life-history studies were started at Benton Harbor, Mich., in 
1915 and completed in 1916. 
Adults were reared separately from larva? collected on the two host 
plants and were identified as Gelechia confusella, by Mr. August 
Busck, of the Bureau of Entomology. 
HISTORY. 
The adult of Gelechia confusella. was first described by Chambers 
(l) 1 in 1875, but with no mention of the source of his material. 
Pettit (4), under the heading "A new peach worm." writes as 
follows : 
A number of worms working in peach leaves were received from Mr. T. D. 
Atkinson, of Holland, Mich., on September IT. They were lepidopterous larvse 
and were said to be very troublesome. The same species was received on July 
3, 1899, from Monroe, Mich. One or two complaints were made from other 
places, though no specimens were sent. 
These are apparently the only published accounts of the occurrence 
of this insect. 
SYNONYMY. 
In 1899 Pettit (1) described the larva of this insect and figured 
the larva and pupa, designating them "Peach leaf-binder, Depres- 
saria persicaeellei Murt.'' In the same publication (5) the adult is 
described as Depressaria persicaeella by Miss Mary E. Murtfeldt, of 
Kirkwood, Mo., from material sent her by Mr. Pettit. Miss Murt- 
feldt. (6) changes Depressaria persicaeella Murt,, to Gelechia. 
Dyar (7) lists Gelechia confusella Cham., with persicaeella Murt. 
as a synonym. Busck (8) lists Gelechia confusella Cham, with 
synonyms Depressaria persicaeella Murt. and Gelechia persicaeella 
Murt,, and makes the following note: 
Cotypes of Miss Murtfeldt's species are in the United States National Mu- 
seum under type No. 4697. The species is very close to the foregoing, and I 
have no doubt is the same as Chambers's Gelechiu confusella, the type of which 
is lost but the description of which tallies in every detail with the peach feeder. 
In 1904 Pettit (9), under the name "The striped peach- worm 
(Gelechia confusella) ," copied part of his former description and re- 
produced the figures of the larva and pupa of 1899. designating them 
as the " striped peach-worm." The synonymy stands: 
Gelechia confusella Cham.. 1ST5. 
Depressaria persicaeella Murt.. 1S99. 
Gelechia persicaeella Murt., 1900. 
The writer has accepted the name " striped peach worm," as it 
seems to distinguish this insect from all other peach feeders and 
briefly describes the larva, which is the only stage commonly seen.
