34 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
trunk of which were taken 14 pupa, 1 larva in cocoon, and 28 larvee 
-of various sizes. 
The attack of this insect is somewhat similar to that of the peach 
borer, but differs in many respects. Apparently it attacks none but 
injured trees, where the bark has been injured in various ways, and 
it is therefore usually found in old trees where this condition is more 
likely to occur (see Pl. VI, fig. 3). Further, the larve occur upon 
the trunk as a rule, make more irregular and longer burrows, and 
generally follow the outlines of wounds or along the edges of the 
cracked bark. They may be found, however, at or slightly below 
the surface of the soil and above the crotch or fork of the tree in the 
larger branches. The larvee feed on the soft tissues of the hving 
bark, and an infested tree exudes a considerable amount of gum from 
the area in which they are working. In some of the Georgia and 
Maryland peach orchards groups of old, scarred trees have been 
found with their trunks literally honeycombed by the channels of 
these larvee, and this is hkely to be the condition in any neglected 
orchard in which the trees have reached some size. An average of 
two larve to the tree was found in 14-year-old trees in Georgia in 
1906, but occasionally individual trees were discovered harboring as 
many as 40 or 50 specimens of the insect in various stages. 
DISTRIBUTION. 
The lesser peach borer is rather widely distributed in the United 
States, to which it is native. In his List of North American Lepi- 
doptera, Dyar (1902) simply gives “ U. S.,” denoting general dis- 
tribution. Beutenmiiller (1901), in his monograph of the Sesiide 
of America North of Mexico, gives from Canada to Florida and 
Texas, westward to the Pacific. It has been recorded from the 
following States: New York and adjacent portions of Canada, Penn- 
sylvania, New Hampshire, Massachusetts, Illinois, New Jersey, Ohio, 
California, North Carolina, Minnesota, Maryland, District of Colum- 
bia, Virginia, and Georgia. It has been recorded as common and 
locally injurious in New York State and Ohio. The records of this 
Bureau (Quaintance, 1906) report 1t common in Maryland, western 
New York and circumjacent territory, and in Georgia, where it is 
especially abundant. It is known to occur on peach in New Jersey, 
Ohio, New York, Virginia, Georgia, District of Columbia, and 
Maryland. 
LITERATURE. 
The literature of this insect is not extensive. Bailey (1879) gives 
the only account of its life history yet published, and his description
