. As regards the special emphasis given by Kusnezov to small deviations in the wing venation, it is well to remember that Emery in 1922 already pointed out that the venation in this genus is quite inconstant. Since to my knowledge no formal synonymy has as yet been published for the present form, it is done so at this place.

is quite common in the fields in the Sao Paulo City area. The workers forage on the ground - they never climb up on plants - and have been seen collecting flowers of Schinus terebinthifolius and Bacharis dracunculifonia, seeds of Bidens pilosus, and caterpillar droppings. The booty is taken back to the nest or deposited on the outside round the entrance. The tiny ants are very timid, feigning dead when disturbed. While foraging, they are often attacked by other ants, especially by

<paragraph id="5A10253A941F2A477A8884E7D10C3A38" pageNumber="424">The fungus-garden bears a peculiar aspect, consisting of narrow and elongate strips, 1.5-4.5 cm in length and 1.5 cm in width, suspended from the ceiling of the cavity like clothes hung up in a closet. The strips are yellowish-brown in color and are made up of tiny bits of plant material woven together by the mycelium of the fungus. Often, in nearby holes, stores of larger pieces of plant material are found piled up in heaps, perhaps to allow for fermentation before being used as substratum for the fungus-culture. Refuse is constantly being removed from the nest and deposited near the entrance.</paragraph>

Luederwaldt counted once a maximum of 21 openings to a single nest. In the dry season, the workers build around the orifice of the entrance mounds of loosely piled up earth crumbs, which are either washed away by the first rain, or cimented together as craters.</paragraph>

The colonies are relatively small and the maximum number of workers to a nest probably does not exceed several hundreds. Nuptial flight takes place at clay-time from October to February, the actual mating of both sexes is accomplished sitting on leaves. Occasionally only

is exceedingly common, the mating season occurs early in spring after the first warm rain, principally during the month of October. The outward appearance of the nest site, the structure of the mounds and craters, the collecting of flowers and seeds seem to be constant for the species, according to my field experience in Sao Paulo and Goias States.
