This ant is one of the most widely distributed species ; it is also one 
which varies greatly in colouring ; hence has arisen the confusion which the 
above synonym exhibits. The F. barbara of Linneus is a form of the 
species which has the head and antenne red; the F. juvenilis of 
Fabricius is a black variety. The A. capitata of Europe, according to 
Nylander and Mayr, varies from individuals totally black to others having 
the head and legs red, with the thorax more or less obscurely so. These 
observations apply to the worker only ; the male is, I believe, always black ; 
the female is sometimes, but rarely, as highly coloured as the worker. The 
numerous specimens from Palestine exhibit various shades of coloration ; 
the majority being, however, more highly coloured than any which I have 
seen captured in Europe. The head, thorax, legs, and in some instances, 
the nodes of the petiole also are entirely bright red; of those taken in 
Jerusalem, some are highly coloured, whilst others are quite black. The 
species has not been discovered in England, but it is common in many 
parts of France, Germany, Austria, Hungary, Dalmatia, Italy, Sardinia and 
Sicily ; I have also received it from Portugal. The nests of this ant are 
frequently much infested by a myrmecophilous beetle, Pycnidium testa- 
ceum. 
ATra structor. (Formica structor, Latr. Fourm. p. 236.—Formica 
lapidum, Fabr. Syst. Piez. p. 406.49 $.—Formica rufitarsis, Fabr.

This species has not been found in England, but is scattered over great 
part of Europe, having occurred in France, Italy, Germany, Austria, Dal- 
matia, and Switzerland ; it has also been found in Algeria,
