4 IOWA STUDIES IN NATURAL HISTORY 
corded by Forel from Barbados and Guadeloupe. The species 
was first found on St. Thomas but has since been taken in 
many widely separated localities: Madeira, Syria, East 
Indies, Madagascar, Florida, ete. 
Monomorium minutum Mayr.—Barbados (H. A. Ballou) 8 Q 
¢. The specimens are very close to if not identical with the 
typical form of the species from Southern Europe. There 
ean be little doubt that this, like the following Monomoriums, 
has been introduced into the islands by commerce. 
Monomorium carbonarium F. Smith subsp. ebeninum Forel.— 
Antigua: St. John (Stoner) 8. 
Monomorium floricola Jerdon.—Barbados (Forel). 
Monomorium (Parholcomyrmez) destructor Jerdon.—Antigua: 
St. John (Stoner, Wheeler) %. I took this ant on the flowers 
of a Bignoniaceous tree in the botanical garden. Introduced 
from the Indomalayan Region. 
Monomorium (Xeromyrmex) salomonis L. subsp. subopacum 
F. Smith— Antigua: St. John (Wheeler) %. Running on 
logs near the wharves. Evidently introduced from Spain or 
North Afriea. 
Solenopsis geminata Fabr.—Antigua (Amer. Mus. Exped.) 8 ; 
Barbados (Forel, H. A. Ballou), Bridgetown (Wheeler) 8. 
Pheidole fallax Mayr subsp. jelskii Mayr var. antillensis Forel, 
22 % —Antigua (Stoner) 3%: St. John (Amer. Mus. Exped.) 
83. Barbados (Forel, Stoner) 2£ %. Also recorded by Forel 
from Guadeloupe and common on many other West Indian 
Islands. 
Pheidole subarmata Mayr var. elongatula Forel.—Barbados 
(Forel) 26 &. 
Crematogaster (Orthocrema) brevispinosa Mayr var. breviden- 
tata Forel.—Barbados: Bathsheba, 200 m. (Forel) 8%. 
Crematogaster (Orthocrema) brevispinosa Mayr var. minutior 
Forel.—Barbados: Bridgetown (Wheeler) %, running on 
tree-trunks. 
Crematogaster (Orthocrema) carinata Mayr.—Barbados: Bridge- 
town (Wheeler) & ; nesting in the bark of living trees. This 
species was originally described from Brazil, whence it may 
have been introduced into Barbados. The specimens agree
