SOME ANTS FROM THE BAHAMA ISLANDS
BY WILLIAM MORTON WHEELER
Biological Laboratories, Harvard University Our knowledge of insect distribution in the Bahamas is very meager, limited as it is to a very few of the nearly seven hundred islands and cays composing the archipelago. Of the ants, a group of greater importance in zoogeograph- ical discussion than many other families or even orders less intimately dependent on the soil, I have records from only three of the islands. The account of these insects which I published nearly 30 years ago1 was based on material which I collected on New Providence and Andros. Mann, 1920, in addition to recording and describing several new forms from the same localities, cited seven species collected by Bluff on Eleuthera Island2. I was glad, therefore, to receive from Dr. David Fairchild and Mr. James Greenway a col- lection of ants which they made on New Providence Island and on some thirteen of the other islands while they were collecting plants, birds and mammals on two expeditions, during 1932 and 1933, of Mr. Allison Armour's yacht, the "Utowana." Both gentlemen accompanied the first expedi- tion, but owing to Dr. Fairchild's illness, Mr. Greenway alone collected ants on the second. The collection comprises 22 forms, and though there are no new forms it furnishes two new records (Zridomyrmex p~uinosus and Camponotus planatus) for the archipelago.
