418 Formicides de V Antille St. Vincent. 
the machine ; partly in the ground near the surface. In 
places there were galleries, covered with a substance 
apparently formed of wood-fibre and earth. I could find 
no larve, and no males nor females, though I dug deep. 
Probably this was a branch of the main nest, which 
may have been some distance away. The workers major 
were numerous, probably one-fourth of the whole. The 
place was quite near the seashore. 
(49 c). Petit Bordelle Estate ; open land near the sea. 
Dec. 15th. A very large community (eight or ten 
thousand, I should think), under turf on a rock; shore 
of a stream. The chambers were large, some of them 
four inches long and wide, but not high; and they were 
partly built up with walls of wood-fibre or some similar 
substance. The passages were numerous, and the whole 
formicarium occupied a space of about two square feet. 
The workers major are not numerous; about as one to 
twenty compared with the workers minor. Only one 
female could be found. The larve were numerous. This 
ant walls in a large proportion of its works, both pas- 
sages and chambers, with the wood-fibre substance 
mentioned above. It does not tunnel more than an inch 
or two below the surface of the ground, so far as I can 
discover. 
(44d). Same locality and date as No. 49 c, but another 
nest ; under a stone. Most of the space under the stone 
was occupied by a large chamber, about 6 x 4 in., but 
not high, around the outside of the stone; next the 
ground were other chambers, formed of the wood-fibre 
substance. Apparently this was only a part of the nest, 
with branches under other stones. Only one female 
found. 
The species is common at Petit Bordelle, but I have 
not been able to find males.
