94 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
puddling the surface. Over this was placed a lantern chimney upside 
down, the top of the chimney just fitting inside the top of the tumbler. 
A piece of cheesecloth over the open end of the chimney completed 
the cage. 
About two days after hatching the larve were transferred to 
fresh foliage, and thereafter the foliage was changed as often as 
necessary. Even with this care only a small percentage of the indi- 
viduals confined were carried through to maturity, and many of the 
lots were complete failures. However, a great deal of information 
concerning the life history and habits of the species was obtained. 
LIFE HISTORY. 
THE ADULT. 
The adult sawflies (see fig. 24, g) are very active little insects. If 
one is observed on a leaf it will be seen to run back and forth across 
the leaf on the upper side, apparently peering over the edge, occasion- 
ally stopping for a moment at one of the nectaries at the base of the 
leaf and sipping the nectar. This sort of food seems to constitute 
their diet, as, in addition to visiting the peach-leaf nectaries, they 
were also observed visiting near-by cotton plants for nectar and honey- 
dew, and one was seen on Japanese quince. 
The adults first appear in the spring, in the latitude of Tallulah, 
about the Ist of April and can be found at any time thereafter until 
cold weather in the fall. Morgan (loc. cit.) observed that the adults 
appeared most abundantly toward the end of each month, and con- 
sidered this as an indication of the different broods. This tendency 
was not noticed at Tallulah. Moreover, eggs and larve of all sizes 
could be observed at the same time, and it hardly appears that shere 
would be any such distinctness of broods. During the year there 
are probably seven generations of the earliest individuals in the lati- 
tude of Tallulah, but owing to the confusion resulting from the over- 
lapping of generations, it is impossible to determine the exact number. 
Six of the seven are summer generations and the seventh is the 
hibernating generation. Of the latest individuals of each generation 
there are probably not more than three or four summer broods. 
OVIPOSITION. 
The act of oviposition was not observed, but from the position of 
the egg it would seem that the female inserts the ovipositor in the 
leaf from the upper side, usually close to the midrib or one of the 
larger veins, and by moving it about from side to side separates the 
lower epidermis from the other leaf tissues in a space about one and one- 
half millimeters in diameter and more or less circular in outline. In
