19,1 Light: Notes on Philippine Termites, II 35 
It was first found by Mr. McGregor and myself (No. 188) 
on October 3, 1920, at Culi Culi, Rizal Province, near Manila, 
when two soldiers and numerous “workers” were collected. 
Later, November 19, more extensive collections were made from 
the same tree, numerous soldiers and very many “larvae” and 
“nymphs” being collected (No. 289). The termites were found 
living in channels deep in the heartwood and were apparently 
rapidly destroying the tree. At the first collection one side of the 
tree, which was dead, contained in numerous tunnels near the sur- 
face large numbers of workers and soldiers of a species of Nasuti- 
termes, whose tunnels were separated internally by very thin 
walls from those of the Kalotermes colony. Such associa- 
tions, whether chance relations or not, are very common. In 
the case of Prorhinotermes luzonensis, described below, three 
species were involved, Prorhinotermes, a Hospitalitermes species, 
and a Neotermes species. Prorhinotermes gracilis was also 
found in close association with a Neotermes species. 
At the second collection many “nymphs” were found, some 
large with large wing pads, others small with but slight begin- 
nings of wing pads but easily distinguished by their opaque white 
color as contrasted to the dirty white color of the posterior ab- 
dominal region of the “workers”, many of which were as large as 
the largest nymphs but showed no wing pads. It was only at 
this collection that the long-headed soldiers were taken. 
Were it not for their presence in both colonies one might sus- 
pect that they represented a different species, so distinctly dif- 
ferent are they from the more numerous short-headed soldiers. 
A second colony, living like the first in ipil-ipil, was found 
by Mr. McGregor and myself on December 25, 1920, while on a 
collecting trip to Batangas, in the municipality of Rosario, Ba- 
tangas Province, some 70 kilometers from the first colony. The 
finding of this second colony in the same tree species makes it 
seem that the species is a regular inhabitant of this tree, whether 
it is able to live in others or not. One or more Neotermes 
species also inhabit the ipil-ipil as they do also the guava, 
the cacauate ( Gliricidia maculata HBK) and the ciruelas 
(Spondias purpurea Linn.) ; but many examinations of the last 
three trees, while producing large collections of Neotermes, have 
failed to show Kalotermes mcgregori or any related species. 
On March 31, j 1921, Mr. McGregor and I again visited the 
colony at Culi Culi and cut down the tree for further study in 
the laboratory. The termites had been driven by the dry wea- 
ther to the deeper and damper portions of the tree, particularly
