FROM THE HOLY LAND. 33 
strewed with the mangled remains of both combatants; but he does not 
appear to have ascertained whether the F. viatica carries off the Atta in 
the pupa or perfect condition. Probably the former, since, judging from 
analogy, it would appear necessary that such should be the case, as under 
such circumstances the F. fusca in the nest of F. sanguinea appears to 
form, as it were, an absolutely necessary part of the community. Probably 
such perfect individuals as are sometimes carried off by slave-making ants, 
are not intended to form part of the living population. Mr. Bates, who 
resided several years in Brazil, communicated to me some very interesting 
accounts of the habits of various predaceous species of ants. Not only did 
he observe the slave-makers carrying off pup from the nests of more 
peaceable communities, but he also witnessed the slaughter of the defence- 
less species—their furious assailants tearing the larger and more weighty fe- 
males limb from limb, and then carrying away the mangled remains to 
their own habitations. Such, probably, is the fate of such living examples 
as may be frequently observed vainly struggling with their more warlike 
invaders. 
M. Roussel observed Atta cephalotes in great numbers, living in perfect 
harmony, in the nests of F. viatica.

A most widely distributed species, being found in England, France, Ger- 
many, Austria, Italy, Algeria, and also in Palestine. Specimens from 
North America have also been examined, which I am unable to separate 
from this species. 
ForMICcA "BIPARTITA.  F. operaria. Rufo-ferruginea ; metathorace

Worker. Length 2 lines. The head, thorax, and legs rufo-ferruginous, 
smooth and slightly shining, the eyes black; the thorax much com- 
pressed behind; the metathorax obliquely truncate, concave above ; 
the lateral margins acute, terminating posteriorly in an acute angle, or 
short spine; the scale of the peduncle oblong, notched above, incli- 
ning forwards, and fitting into the oblique slightly concave truncation 
of the metathorax: when viewed sideways, it is wedge-shaped ; the 
abdomen ovate, and shining black. 
I at first sight mistook this very distinct, and apparently undescribed 
ant, for a species belonging to the genus Myrmica, to many of which it 
bears a strong resemblance. In size, general form, and more particularly 
its spinose metathorax, it approaches the Myrmicide; but its having a 
single scale, or node, at once points out its situation to be amongst the 
Formicide. I much regret having only workers for examination; and 
although upwards of thirty were captured, not one possesses an antenna. 
Had all the sexes been before me, I have a strong impression that this
