wheeler: the ants of cuba. 479 



at least provisionally, as indigenous; second, forms known also from 

 the neighboring islands or from the adjacent mainland (Florida, 

 Mexico, Central and northern South America); and third, tropico- 

 politan forms of Old World origin comprising the "tramp" species 

 which have been introduced into the island by commerce. 



The indigenous forms, thirty-four in number and comprising 44.1% 

 of the Cuban ant fauna, are the following: — 



Euponera succedanea Pheidole cubaensis 



Leptogenys falcata bakeri 



Pseudomyrma opacior barbouri 



pazosi Solenopsis cubaensis 



cubaensis Atta insular is 



Monomorium cinnabari Strumigenys gundlachi 



Macromischa purpurata Tapinoma cubaensis

squamifera Prenolepis anthracina 

 versicolor gibber osa

 lugens rogeri 



punicans Camponotus mestrei 

 gundlachi " sphaericus 



" poeyi " sphaeralis 



C rem atog aster sanguinea " gilviventris 



" torrei " riehli. 



Of these the most striking are the nine species of Macromischa, 

 which show that Cuba is the center of distribution of this genus, the 

 large Atta insularis, the only Atta sens. str. known to occur in the 

 West Indies, and the small section of the genus Camponotus compris- 

 ing the two peculiar species C. sphaericus and sphaeralis. 



The following forms, thirty-six in number and constituting 46.7% 

 of the ant-fauna, are more or less widely distributed through the West 

 Indies and tropical continental America: — -
