my diagnosis, as the median runs parallel to and midway be- 
tween the radius sector and cubitus . 2 
The protruding margin of the antennal foveolse of the soldier, 
the very large, characteristically shaped pronotum, the presence 
of wing pads, and the characteristic toothing of the mandibles 
suffice to differentiate this species from other species of the 
genus. 
I have named this distinct species in honor of Mr. R. C. 
McGregor, ornithologist of the Bureau of Science, who helped 
me to collect it and whose aid and interest have to a great extent 
made possible the rapid collection of local Philippine termites. 
DISTRIBUTION AND BIOLOGICAL NOTES 
This species was found living in tunnels very close to, if not 
actually within, the live wood of a small leguminous tree, Leu - 
caena glauca Benth., known locally as ipil-ipil (Tagalog). In- 
troduced from America, this plant is widespread about towns 
and country dwellings where its rapid growth, which enables 
it to drive out cogon grass, and its usefulness for firewood 
and fence posts make its propagation worth while. The very 
interesting question arises at once as to whether this species is 
found in other and native trees or is confined to this plant and, 
if so, whether it was introduced with the plant and is, therefore, 
an American species, or whether it has become adapted to this 
habitat since the introduction of the plant here. It seems very 
unlikely that plants large enough to harbor these termites were 
brought here, but it is by no means beyond the range of pos- 
sibility. A review of the American Kaloterm.es species shows 
this species to be most nearly related to K. jouteli Banks, which 
it resembles in the shape of the head, the toothing of the man- 
dible, the size of the third antennal joint, etc. It differs from 
it in many points, however, such as size and shape of the pro- 
notum, shape of the third antennal joint, the projecting margins 
of the antennal foveolee, etc. It appears to be a new species, 
therefore, whether introduced from America or not. 
' Since writing the above I have taken two winged adult Kalotermes 
specimens in Cebu Island. Whether these belong to this or some related 
species cannot be determined until the series is completed in either locality. 
There remains the possibility that the form described here represents the 
soldiers and workers of K. indicus Holmgren known from the adult only, 
but the widely separated habitat makes this extremely improbable.
