makes slightly more than a right angle with the mandibles, 
and in the shape and position of the spine near the antennal 
foveola, which in C. cynocephalus is simply an extension of the 
anterior and anterodorsal margin of the foveola. Specimens 
just received of the Hawaiian Cryptotermes-like species, kindly 
sent me by Mr. David T. Fullaway, entomologist of the Bureau 
of Agriculture, show a very striking difference among other 
points in their greater size. From what Mr. Fullaway has told 
me of the venation of the adult I am led to believe that this as 
yet undescribed species must be placed in another genus rather 
than in Cryptotermes. 
DISTRIBUTION AND BIOLOGICAL NOTES 
House termites, living in the dry, seasoned wood of planks 
and boards of houses, in furniture, in picture frames, etc. The 
specimens on which this species is based were found together 
with those of Planocryptotermes nocens sp. nov. (see below) by 
Prof. José I. del Rosario, of the department of chemistry, Col- 
lege of Liberal Arts, University of the Philippines; they were 
living in boards of his house and were kindly collected for me. 
Whether the two species were in the same boards or not I do 
not know since the material was collected under the impres- 
sion that but one species was involved. This was true also 
of the second colony of this species collected which was found 
living in the same board with P. nocens sp. nov. This colony 
was collected by Cipriano Gamboa on March 7, 1921, and in- 
cluded a few winged adults (No. 443). <A third, larger, colony 
(No. 448) was found by Paulino Aguila in the boards of a 
shouse on March 8, 1921, and contained numerous winged adults. 
This would seem to be very near the time for swarming, as 
many of the adults were fully pigmented and able to fly freely.® 
Among the hundreds of “workers” and adults, only five soldiers 
were found. These, like those of the colony mentioned above, 
were dead, as the boards had been exposed to the sun. Since 
* Since writing the above, winged .specimens of C. cynocephalus have 
been taken at various times during the months of June and July in my 
house in Paco, Manila, which is badly infested with house termites. These 
adults are never numerous and, strange to Say, emerge in the early 
morning rather than at night, as is the habit of Planocryptotermes and 
most other termites. During the latter part of June and the early part of 
July a few of them were to be taken on my window curtain each morning 
and a deilated pair of these, our tiniest adult termites, were commonly 
to be seen in the early morning coursing excitedly over my washstand.
