trees or stumps ; sometimes at roots of Bromeliz growing 
on trees, and occasionally under stones on dry ground. 
Several hundred individuals are found in a formicarium. 
When disturbed they are active and pugnacious. The 
workers minor are often seen on trees and foliage during 
the day, but I believe that the species is mainly noc- 
turnal. 
(2a). Collected at various places, 8000 ft. to seashore. 
(2b). Seashore; southern end of the island at the 
“Villa” Estate. Oct. 14th. Many ants were found 
under a block of coral lying on the sands, but I could 
find no young; and perhaps this was not a nest. 
(2c). Bowwood Valley, near Kingstown, 800 ft. Oct. 
21st. Formicarium under stone ; open, dry hill-side. 
(2d). Richmond Estate; open valley. Oct. 31st. 
Formicarium in a rotten stump. 
(2e). ‘Villa’? Estate; southern end of island. Nov. 
20th. A small colony in a curled dried leaf in rubbish 
on the ground; shady place by seashore. 
(2f). Hermitage Estate, Cumberland Valley, 1000 ft. 
Open hill-side ; lower side of a log. Formicarium was 
in a hollow of the log, about 38 xX 2 x 2 in., apparently 
made by the ants; the opening of the cavity was walled 
in by a thin fabric of wood-fibre, pretty strong ; through 
the middle of this was a hole for exit. The colony was 
small (about 100 workers). I could find no male nor 
female, and no other chambers were discovered. 
(29). Windward side; sea-coast near Georgetown. 
Jan. 8rd. On bushes. 
2. Camponotus auricomus, Roger, ¥ et 2 (No. 8). 
Variété. 
Longue de 4, 8 & 7 mill. avec le devant de la téte, les scapes et 
le ler article des funicules rougedtres, tandis que le reste des funi- 
cules, le thorax et l’écaille sont noirs. 
(8). Very common on foliage of bushes, &c.; open 
places or dry thickets, below 1000 ft. All parts of the 
island. 
_ (8a). Near Chateaubelais (leeward). August. Thickets 
not far from seashore; on bushes. The formicarium is 
made in rotten wood, or rarely under stones, the ants 
apparently choosing that which has been riddled by 
termites. It is of considerable extent, and may contain
