general external structure ; classification (by genera and species, in sepa- 
rate tables founded on the characters of male, female, and workers) ; 
description of new forms ; synonymy from Mayr & Roger, and of 
Huber’s & Ebrard’s species ; anatomical and physiological notices includ- 
ing monstrosities ; architecture or structure of nests and their adjuncts, 
and also of other operations of ants ; geographical distribution in Swit- 
zerland ; importance in the scale of nature ; observations on habits 
(brief reference to parasites); consideration of ants on the Darwinian 
hypothesis ; and bibliography. The plates contain figures of various 
portions of internal and external anatomy. The author’s excessive pro- 
lixity renders any abstract almost impossible ; he nevertheless complains 
of the length of Traherne-Moggridge’s observations [91 pages, 8vo ; 
ForeFs own being 500, 4to !], which, according to him, add nothing to 
those of Lespes (Rev. Coiirs. Sci. I860). The worker of Brachymyrmex, 
Mayr, the $ of Ponera punctatissima, Rog. (p. 92), and the $ of Tcmno- 
tliorax recedens, Nyl. (p. 94), are described. The author also describes 
Leptothorax lutxm^ nov. stirps” (worker), and“ Lcptothnraxtnhcro-niyri- 
cepi^, form, intorm.” (with (lie statement that the males of L. iuhcruniy 
F., and L. nigriccps, Mayr, are not yet described), p. 95. A new genus 
and two new species are also described (in several parts of the work).
