JURINE. 
It appears to me, that M. Latreille has de- 
scribed an individual of this species, or, if you 
please, variety, in his History of Ants,  His- 
toire des Fourmis,” whilst speaking of the female. 
A very remarkable difference between them, is, 
that the rings of the female of this latter species 
have infinitely more lustre than those of the 
Sormer. The fallow colour is also more bright. 
The denominations of dos noir and dos rouge 
have been given from the colour of the worker.
