seats or door-posts. ‘This species has not shown any evidence of 
using glutinous secretions in repacking the excavated chambers 
or tunnels; but a few of the chambers were repacked with loose 
pellets—fwces. This species is very destructive to ash wood, 
and can readily bore hard oak. Eating out the interior of the 
wood in chambers, they cannot be easily dislodged, 
In the classification of the Termes and the Eutermes, there is 
great confusion. ‘The latter have been separated from the 
former on account of asupposed constant difference in the vena- 
tion of the wings, which does not seem to hold good with the 
several species from the Isthmus at least. The present classifi- 
cation puts into the same genus—/Hutermes—species having 
soldiers provided with long, curved mandibles, and species having 
soldiers with their heads terminating in a long ‘‘ nose ” or beak 
from which they eject a minute glutinous pellet or shot when 
attacked. Upon the Isthmus, the habits and nests of species 
having soldiers of the first kind are entirely distinct from those 
of the species haying soldiers with long noses (nasuti). ‘T'o 
avoid confusion, in this paper, species in which the soldiers have 
long, curved mandibles will be mentioned as Termes, and those 
having nasuti soldiers as Hutermes. 
Five distinct species of Termes have been thus far collected 
upon the Isthmus: 7. e., the soldiers and workers of as many 
species have been found, but the queen of only one of these has 
been obtained. One species builds conical nests of mud or 
earth, after the manner of some of the African Termites, the 
largest found being three and one-half feet in diameter, and the 
same in height. This nest is near Corozal Station of the Panama 
Railroad. 
The nest of the species of Termes in which the queen was 
found was upon a decaying stump on Kenney’s Bluff, across the 
bay from Colon. The workers are comparatively small, less than 
three-sixteenths of an inch long, The umber-colored nest had very 
small passages,—some of them formed by eating out the wood, 
while others were constructed. The queen’s cell was nicely 
formed, the interior being quite smooth. The other species of 
Termes have been collected in the pieces of wood or trees upon 
which they were feeding. The only portions of nests found are 
those obtained inside the larger posts of buildings which they 
were attacking. ‘These were perhaps only auxiliary nests, as 
queens or their cells were not found. The Termes make coy- 
ered galleries leading from their nests, but not so extensively 
or conspicuously as the Hutermes, at least not upon the Isthmus. 
Most of the species of Termes, when eating the wood of a 
building, make galleries between boards or through the interior 
of the wood, never breaking through to the exterior.
