A Species of Collembola Found With Termites 
GERTRUDE BACON 
In a grove of live oaks near Claremont, there are great 
masses of dead leaves under the trees. Under this mantle of 
dry foliage there is often a considerable amount of decomposed 
material which may retain some moisture for a time. In this 
location there are many Collembola of various sorts. In places, 
twigs from the trees are mingled with the damp remains and 
these are very often inhabited by termites or white ants. These 
insects live in the tunnels which they make in every direction 
in the wood. In these spaces and perhaps also in some smaller 
crannies a small white insect was found quite constantly. At 
first it was supposed that these were blind Collembola without 
the furcula, but when touched they jumped very quickly. It 
was also found that they had eyes. 
These forms were found to correspond exactly to Entomo- 
brya binoculata, described by Harald Schoett in his article on 
North American Apterygogenea, in the Proceedings of the 
California Academy of Sciences, volume VI, 1896. 
Length—1.5 mm. Color—Opaque white. Body—Subecylin- 
drical, very hairy. On the head and neck the hairs are long 
and clubbed. Hyes—One on each side of the head. These are 
Ideated in irregular masses of hght brown pigment in some 
specimens. There seems to be some indication of a bilobed 
condition of the eye spots. Antennae—Not as long as the body 
but longer than the head. The segments are: I shortest, IL 
and III subequal, IV nearly twice as long as III. Claws—Two. 
Superior claw has three teeth on the inner margin, the two 
upper of which are opposite each other. The inferior is lan- 
ceolate and unarmed. Fwrcula—This does not quite reach the 
ventral tube. Dentes shghtly longer than the manubrium. 
Mucrones—With two strong teeth and a slender basal one 
which points distally and almost reaches the middle tooth. This 
species was found at Berkeley, California, but nothing is men- 
tioned by Schoett as to the distribution. 
It is possible that this species may occur in other locations 
than in the dwelling places of white ants, but so far we have 
found them in no other environment.
