A REVISED LIST OF THE BRITISH ANTS. 

 By Horace Donisthorpb, F.Z.S., F.E.S. 



I hope shortly to publish the distribution of the ants which 

 occur in Britain, as far as is at present known. It seems to me 

 therefore desirable first of all to publish a list of our species in 

 the proper order and with the correct synonymy. 



It is also necessary to place on a proper footing the different 

 species, subspecies, and varieties. Three of the varieties and 

 one subspecies have been added within the last two years, and 

 it is probable that when more attention has been given to our 

 ants, and more collecting has been done, several other species or 

 forms will be found to exist. 



I use the term "subspecies" instead of "race," as the former 

 is more generally employed now by myrmecologists, though I 

 think perhaps Prof. Porel's word " race " is more expressive. 



The difference between subspecies and varieties in ants is 

 only one of degree. The former is more constant, nearer to the 

 species ; the latter exhibits more hybrid forms and transitions. 



The following is our list : — 



FORMICID^. 



Subfamily PoNERiNiE. 



Genus Ponera, Latr. 

 coarctata, Latr. {contracta, Latr.). 

 punctatissima, Roger. ■
