DISTRIBUTION AND BIOLOGICAL NOTES 
Collected by McGregor and Light on Septem- 
ber 29, 1920, from a hollow guava stub with 
living branches, near the Manila-North Road, in 
Rizal Province, about 100 meters from the Rizal- 
Bulacan boundary monument. 
This small colony was discovered 
while searching for Neotermes, 
one or more species of which 
are very common in guavas; in 
fact, a number of Neotermes 
specimens were collected at the 
same time, probably from tun- 
nels near the surface of the 
wood. In this connection it is 
interesting to note that P. luzon- 
ensis wag also found in agso- 
ciation with, or at least in very 
close proximity to, Neotermes. 
The P. gracilis colony was found 
living in a mass of wood pulp, 
probably fecal matter, similar 
to that used by Neotermes to 
plug up points of entry into a 
limb, and deposited by them 
also in some of their workings. 
At the time this was thought to re. 
be Neotermes waste, but I have ™®
