LIFE HISTORY AND HABITS. 
The winter is passed in various stages of larval development under 
the bark of the trunks of the trees. Upon the approach of warm 
weather, and during warm spells in the winter in the South, the 
larve feed, and as they reach full growth construct cocoons and 
pupate (in March and April in Georgia and Maryland, respectively). 
About a month afterwards the moths begin to emerge and mate, and 
the females. at once commence to deposit their eggs along the tree 
trunks. On account of the unequal development of the hibernating 
larve, the period of 
pupation and _ subse- 
the adults lasts for 
several months. The 
eggs hatch after 
about ten days, and 
the young larve en- 
ter the bark through 
crevices and begin to 
feed. In Georgia, in 
the course of several 
months, these larvee pre. 10—The lesser peach borer (Synanthedon pictipes): a, Adult;

pupate, and the re- 
sulting moths establish another generation in the early fall,

which hibernates as larve. The two generations are considerably 
mixed. 
The seasonal history of this borer is therefore very unlike that of 
the peach borer. It differs markedly in the fact of a partial second 
generation, and the further fact of early spring pupation. 
The egg—The egg (fig. 10, 6) is a small, compressed, elliptical!- 
oval, reddish-brown object, similar in general to the eggs of the 
peach borer and other members of the family .geriide. It har- 
monizes in color with the bark of the trees upon which it is deposited, 
and on this account is difficult to find. Seen from the side the ante- 
rior end is truncate, but viewed from in front it is found to be con- 
cave, the micropyle situated in the center of the concavity. The 
upper side of the egg, as seen when in position on a tree, is com-
