inhabiting larve are found (in peaches) during the latter part of July 
and August and mature durivg September,” * and is entirely opposed 
to the statement of two prominent California authorities, that the small 
larve bore into the bark of infested trees and there pass the winter in 
the larval stage.t 
April 20, 1897, larve of a twig-borer were received from Halsey, 
Oreg., and between that time and May 25, when the last specimens 
were received, the work of this insect was reported from Halsey, Hugo, 
Lookingglass, Oakland, Dundee, Yoncalla, Junction, Bellefontaine, 
and Granger, and was observed at Corvallis, Liberty, and Rosedale. 
Mr. H. E. Dosch, horticultural commissioner for the First district, also 
writes me that he has numerous letters regarding this pest from various 
parts, and Mr. C. L. Dailey, commissioner of the Second district, writes 
that the ‘“ pest is everywhere, and small trees are literally denuded of 
terminal buds.” Mr. Morrison, of Dundee, Oreg., not only sent laryie 
in growing twigs, but also sent sections of bark containing burrows in 
which the larvie had wintered, and several larve that he had taken from 
the burrows. This. of course, corresponds with the published accounts 
of Craw and Woodworth, above referred to, except that they have 
unquestionably referred to the larve that winter in the bark and attack 
the young twigs of various trees as the larve of A. lineatella, and have 
failed, so far as I can learn, to call attention to the great difference 
between these larve and the larve of A. lineatella as found in straw- 
berry crowns. 
The first twig-borers received were slightly more than one-fourth inch 
long, and were of a dirty brown or dull grayish-black color, with head, 
first and last segments, and true legs shining black. In general appear- 
ance they so closely resembled the larve of the bud moth ( 7metocera 
ocellana) that at first I mistook them for that insect. I soon noticed, 
however, that the habits of the two species were entirely different, and 
that every larva of the twig-borer was readily distinguished by its 
shining black terminal segment. But this character, together with the 
general color of the larvie, rendered them so unlike the larve of Anar- 
sia lineatella (?) as described, and as seen in strawberry plants and in 
prune twigs last June, that it did not occur to me that they could belong 
to that species until May 17, when four of the moths issued. One of 
these moths was at once sent to Dr. C. H. Fernald, who wrote that it 
Is Anarsiu lineatella. 
The mounted specimens greatly resemble the moths reared from the 
larve in strawberry crowns, but are slightly larger and darker in color. 
The habits of the living moths are quite different. Those reared from 
the strawberry crowns crawl down among the vines even into crevices 
in the soil, apparently for the purpose of depositing eggs upon the
