This latter is somewhat unusual and probably chargeable in part to 
the backward season. ‘The destruction of the leaves at this late 
date can hardly be considered as injurious, since it would do little 
more than hasten the normal fall ripening of the wood. 
Lesser peach borer (Synanthedon pictipes G &R).: 
This species has long been known as an enemy of plum trees in 
New York State. Its life history was worked out rather fully in | 
1879 by Dr James S. Bailey of Albany, who studied the operations | 
of this species on plum trees in his back yard. Subsequent litera- 
ture shows that this form has a decided preference for the domestic 
plum, though it has also been recorded as breeding in a number 
of other trees such as the beach plum, wild plum, cherry, June- 
berry, chestnut and peach. Recent developments show that this 
species may be quite injurious to peach, particularly in the Southern 
States. Its operations upon this tree have also been observed in 
New York. ‘This pest has a somewhat similar habit to that of the 
more common peach borer (Sanninoidea exitiosa Say), 
it differing in that it apparently attacks none but injured trees, 
preferring to work in the vicinity of some scar; consequently it is 
usually found in old trees. The borers make more irregular and 
longer galleries, generally following the outlines of wounds or along 
the edges of the cracked bark. They may occur at or a little below 
the surface of the soil or even above the fork of the larger branches. 
The borers live on the softer tissues under the bark causing, like 
the larger peach borer, an exudation of gum. This species is more 
easily distinguished from the common peach borer by its smaller 
size, and in the case of the male may be separated from the more 
common form by its bearing but two yellow bands on the abdomen, 
they occurring on the second and fourth segments, while the male 
peach borer usually has a band on the posterior margin of each 
abdominal segment. ‘The methods of value in controlling the peach 
borer prove effective in checking this species providing the worming 
is extended to above the fork of the upper branches. Care should 
also be taken to prevent injury to the trunk or larger limbs. A 
more detailed account of this species is given by A. A. Girault in 
Bulletin 68, part 4, Bureau of Entomology, United States Depart- 
ment of Agriculture. 
Lesser apple worm (Enarmonia prunivora Walsh). 
The work of this species is probably familiar to many of our 
orchardists, though it has usually been attributed to the operations 
of young codling moth larvae. This species generally bores just
