I thought it proper to make of the Fallow 
Ants two species, as they are distinguished from 
each other by very remarkable characters, and by 
a. difference in their habitations ; some being in- 
Jinitely larger than others: the former, are situat- 
ed in forests; the latter, alongside hedges and 
meadows. To the second species, I shall give the 
name of the Fallow Ant with the red back, 
(Fourmi fauve, dos rouge) which dwells by pre~ 
ferences on the woods.

eyes, antenna, superior thoracic plate, and 
abdomen, blackish. Scale thick, oval, 
entire. Wings very smoky at their base. 
The first segments of the abdomen cats a 
slightly reddish tint.
