22. Coccids. These were found in the cavities of the 
Cecropias with Azteca. 
It is noteworthy that dead Cecropia logs failed to attract 
borers, although they were carefully examined at different 
times. 
Birds were not seen to visit Triplaris, but the Cecropias 
were observed to be favorite feeding grounds of several 
species, particularly in November. Some of the species 
noted were: 
Forpus spengeli (Hartlaub), a minute, green and blue 
parrot, 
Brotogeris jugularis jugularis (Muller), a small green 
parrot, 
Momotus momota subruf escens Sclater, the local motmot, 
Pteroglossus torquatus nuchalis Cabanis, a toucan, 
Centurus rubricapillus rubricapillus Cabanis, a common 
woodpecker, 
Thraupis episcopus cana (Swainson), a common tanager. 
None of these birds was ever seen to act as if it had been 
attacked by the ants. 
III. Note of Acacia. 
Ant-inhabited acacias were found only near Aracataca, 
in the extreme southern part of the region over which the 
junior author collected. The largest plant examined was 
hardly more than ten feet high. Though he had no oppor- 
tunity to study the relations of the ants to the plants in 
detail, he secured a number of the former from the large 
thorns. They prove to be specimens of Pseudomyrma 
spinicola Emery subsp. gaigei Porel. The types of this 
form were taken by Dr. F. M. Gaige at Fundacion, south 
of Santa Marta, probably from thorns of the same species 
of Acacia. The senior author has found a very similar 
form of Ps. spinicola in the thorns of A. penonomensis on 
the Pacific side of the Panamanian isthmus. The spines of
