REPORT ON THE ANTS 
Collected by the Barbados-Antigua Expedition 
from the University of Iowa in 1918

Although there has been considerable collecting of ants on 
the Windward Islands, only the species of St. Vincent and 
Grenada have been listed hitherto. Professor Dayton Stoner 
has recently sent me the ants which he collected as entomologist 
of the Barbados-Antigua Expedition of the University of Iowa, 
and during July, 1920, I was able to collect on both of the 
islands while on my way to British Guiana. Owing to the pro- 
tracted and almost unprecedented drought, however, I was un- 
able to secure many species. The following list is based on these 
small collections, on material that has been accumulating in my 
cabinet and on that collected by Professor A. Forel in Barbados 
while on his journey to Colombia in 1896. The total is rather 
meager and most of the species are well-known, widely dis- 
tributed West Indian forms. 
Family Formicide 
Subfamily Ponerine 
Platythyrea punctata F. Smith var. pruinosa Mayr.—Barbados. 
First taken on the island by Professor Forel. Professor 
Stoner captured two workers. 
Odontomachus hematoda L. subsp. insularts Guérin.—Antigua: 
St. John (Stoner; Amer. Mus. Exped.) % 9¢. Barbados 
(Forel, Stoner) 3. Bridgetown (Wheeler) 8. This ant is 
common throughout the West Indies and tropical Florida. 
To the many known localities I may add Montserrat and St. 
Kitts, from which I have received workers taken by Mr. H. 
A. Ballou.
