segments. Pronotum 1 by 0.55 millimeter, mesonotum and meta- 
notum broader than pronotum. 
Nymph. — Very numerous nymphs with swollen floatlike wing 
pads united in midline and similar to those described by Snyder 
for P. simplex were present in the colony. These will be studied 
later in connection with the findings of Thompson and Snyder. 8 
DISTRIBUTION AND BIOLOGICAL NOTES 
As pointed out in the discussion under the genus, three collec- 
tions of Prorhinotermes have been made, all in Rizal within a 
kilometer or two of the Rizal-Bulacan boundary. The material 
on which this species is based came from a single colony found 
in a large hollow guava tree about a kilometer from the boun- 
dary. The colony was associated with a Hospitalitermes species, 
probably hospitalis (Haviland) or some nearly related species 
such as H. luzonensis (Oshima). In tearing away the nest of 
the Hospitalitermes species a winged Prorhinotermes was seen 
but in the dusk was not at once recognized as a termite because of 
its light color, and its transparent wings and rounded body. 
Later, large numbers of all castes were collected, but unfor- 
tunately few data were obtained as to the relative positions and 
relations of the two forms. From the same place a number of 
specimens of Neotermes malatensis (Oshima) were obtained. 
These collections were made with Mr. R. C. McGregor on Octo- 
ber 4, 1920, and large numbers of winged adults and nearly 
mature nymphs were found in the nest. 9 
Several isolated winged adults have been collected. One 
(No. 197) was collected by me about the lights of the University 
Club, San Luis Street, Manila, September 27, 1920; another 
(No. 212) was collected from the lights in Quiapo, Manila, 
October 6, 1920; and two others (Nos. 66 and 245) I found 
in my former house in Ermita, Manila, one on August 28, and 
one on October 31, 1920. As adult specimens were found in 
large number in the colony (No. 205) on October 4, it seems 
probable that the winged adults take flight during August, Sep- 
tember, and October, 10 a few at a time probably, as the flying 
’Thompson, C. B., and Snyder, T. E., Biol. Bull. 36 (1919) 115. 
9 Another trip to obtain more data about this colony showed the guava 
tree with the colony to have been destroyed, but another colony was found in 
another guava tree not far away (No. 436). Unfortunately it was im- 
possible to make any extensive collections without destroying the tree. 
10 It is interesting to note in this connection that winged adults of the 
same or a closely related species were taken about the lights in Cebu, in 
May, 1921.
