878 _ The American Naturalist. [ October, 
I have very little doubt, that on many groups of Islands, on 
which, so far as I know, no Formicide have been recorded, 
they will be found, when these Archipelagos will be thoroughly ' 
examined ; for instance the Pelew and Marianne Islands, the 
Carolines, the New Hebrides, the Cook, Paumatou, Marquesas 
and Juan Fernandez. — | 
' It is quite evident, that this distribution of the Formicide 
cannot be explained by accidental introduction. Also here we 
are forced to accept a former Pacific Continent. 
The Fiji Islands have four endemic species of Camponotus ; 
three of Colobopsis; one of Odontomachus; the Tonga Islands 
one endemic species of Camponotus ; two of Colobopsis, one of 
Tetramorium ; the Samoa Islands, one endemic species of Ano- 
chetus, one of Strumigenys and one of Vollenhovia; the Sand- 
wich Islands one endemic species of Ponera, and one of Leptog- 
` enys ; the Galapagos Islands three endemic species of Camponotus, 
and one of Odontomachus. —

species of Camponotus and one of Cardiocondyla (also found in
