 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 Linnaeus is a form of the 

 species which has the head and antenna? red ; the F. juvenilis of 

 Fabricius is a black variety. The A. capitata of Europe, according to 

 Nvlander and Mavr, 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. 



Atta structor. (Formica structor, Latr. Fourm. p. 236. — Formica 

 lapidum, Fabr. Syst. Piez. p. 406. 49 £ . — Formica rufitarsis, Fabr. 

 Syst. Piez. p. 406. 45. $ . — Atta structor, St. Farg. Hym. i. 174. 2. — 

 Myrmica structor, Nyland. Form. Cr. et d' Alger. 85. 10, Div. 2.) 

 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.
