** The Author of these Memoirs, after 
having mentioned in a summary way, 
the facts I published upon the manners, 
&c. of the Rufescent Amazon Ant, says, 
‘ I observed, in 1802, an army of these 
Ants in one of their military excursions. 
They were traversing one of our great 
roads, covering the whole of its breadth, 
and advancing in a column of about two 
feet in width. I attributed this move- 
ment to a forced emigration. . I sus- 
pected, however, from the form of this 
species, before M. Huber had published 
any account of it, that it had_parti- 
cular habits. I found this Ant in the 
woods, in the neighbourhood of Paris. 
The whole of the facts related by this 
Naturalist (Huber) have been fully con- 
jirmed 
* M. De Latreille told me, that he 
had shown this singular phenomenon to 
a skilful English Naturalist, whose name 
I think is Leach.
