NEW ANTS OF THE GENUS MACROMISCHA 
By C. G. Aguayo

The ants of the remarkable genus Macromischa, besides 
being among the most beautifully colored of the Formi- 
coidea, are certainly very interesting on account of their 
extremely localized habitat. 
W. M. Wheeler in a recent paper on this genus (1931) 
has described several new forms, among which were sev- 
eral Cuban species that I had the pleasure of sending to 
him. As I still have some undescribed new varieties re- 
cently collected by Dr. Pedro Bermudez, Colonel George 
Natenzon and myself, I avail myself of the opportunity 
given me by the Guggenheim Memorial Foundation to 
study in the United States, and Dr. Barbour’s permission 
to work in the Museum of Comparative Zoology, to publish 
this small contribution to the knowledge of Cuban ants. 
Wheeler raised to generic rank (1931, p. 4), the sub- 
genera Crcesomyrmex and Antillsemyrmex, both of Mann 
(1920, p. 408), but since among the species described fur- 
ther on Macromischa ivheeleri petri shows intermediate 
characteristics between Macromischa s.s. and Croesomyr- 
mex, he agrees with me in placing them anew as sub- 
genera. 
The position of Antillsemyrmex as a genus was more un- 
certain on account of the intermediate characters shown 
by some species (Wheeler, loc. cit. p. 4), and it seems to be 
convenient to consider it again as a subgenus. 
I cannot but thank Prof. Wheeler and Dr. Bequaert for 
their many helpful suggestions during the preparation of 
this paper.
