ing a yellowish or brownish cast. The 
head is darker yellow and mandibles 
brown. The soldier ants have large brown 
heads, comprising at least one-third of 
their entire bodies. The queen ant is 
much larger than the other forms, while 
the males are small. It is claimed that 
there are no less than 15 kinds of in- 
dividuals in this species. 
Life History 
These termites usually live in dead or 
decaying wood but often work into the 
living and growing tissues. They make 
very extensive galleries through all parts 
and thus often destroy buildings, 
fences, etc., aS well as fruit trees. The 
queen gives rise to all the young, which 
appear in great numbers, especially dur- 
ing the summer months. In the fall or 
autumn winged or migratory forms ap- 
pear and often fly by thousands on dark 
days and towards evening. In habits and 
life history they greatly resemble true 
ants and bees. 
Distribution 
General. 
Food Plants 
As previously stated, these termites 
usually work upon dead or decaying 
wood, but then usually only in the pres- 
ence of moisture. These insects often be- 
come destructive to fruit trees, working 
upon the roots underground and making 
galleries up the trunk. No doubt they 
usually begin to work in the decaying 
tissues but often continue into the 
551 
healthy portions of the tree. Nectarines, 
peaches and apricots seem to suffer most, 
while citrus and other trees and plants 
are also attacked. 
Control. 
Due to their secluded work the damage 
is usually done before their presence is 
known and too late to effect a remedy. 
However, if close observations are made 
in infested districts and their work dis- 
covered the colony may be almost entirely 
exterminated by the use of a liberal dose 
of carbon bisulfid applied in cotton or a 
sponge directly within their burrows or 
under the base of the tree.
