NOTES ON CUBAN ANTS. 
Wm. M. Mann. 
Bureau of Entomology, U. S. Department of Agriculture. 
In a small collection of ants from Cuba sent by Mr. S. C. 
Bruner, of the experimental station at Santiago de las Vegas, 
and collected by him and Mr. H. Ballou, are two undescribed 
species of the genus Macromischa. This increases the number 
of known Cuban species to sixteen, and I think it probable that 
future collectors will find still more of these interesting ants, the 
species of which appear to be very local in distribution and 
difficult to find. 
In addition to the descriptions of these I have listed for 
distributional data several other species of interest. 
Macromischa (Macromischa) bruneri, new species. 
Worker. Length 2.75 mm. 
Head a little longer than broad, as broad in front as behind, 
with slightly convex sides, broadly rounded corners and nearly 
straight occipital border. Clypeus convex, obtusely carinate at 
middle, straight at anterior border. Antennal scapes nearly 
attaining occipital corners; funicular joints 3-8 transverse, club 
rather strong. Thorax rather robust, without sutures above; 
sides of prothorax evenly rounded. Epinotal spines nearly 
approximate at base, not very acuminate, about as long as the 
epinotal declivity. Petiolar peduncle slender, about as long as 
the node, which is longer than high, rounded above, and seen 
from above twice as long as broad. Postpetiole twice as broad 
as petiole, as long as broad and only slightly broader behind 
than in front. Femora slender basally, swollen at middle and 
narrowed apically, with the flexor border rather strongly con- 
cave . Tibi 80 strongly incrassate . 
Moderately shining. Mandibles sparsely striate and with 
several coarse punctures. Head, thorax and epinotum densely 
punctate and subreticulately striate, the latter strongest on
