MANN: THE ANTS OF BRAZIL. 42 
79. Pheidole (Elasmopheidole) aberrans Mayr. 
One colony was found at Independencia. This species is distrib- 
uted along the east coast, in the more arid localities from north of 
Cape San Roque to Argentina. Among the specimens before me 
some of the soldiers have the vertex of head, the thorax and epinotum 
piceous. Others from the same colony are reddish brown throughout, 
agreeing in this respect with a series from Buenos Ayres (Silvestri 
coll.) in the Wheeler collection. 
80. Pheidole (Pheidole) gwilelmi-miilleri Forel subsp. mamore, 
subsp. nov. 
Soldier. Length 4.75 mm. 
Head, excluding mandibles, a little longer than broad, slightly 
narrowed in front, with nearly straight sides, broadly rounded occipi- 
tal corners and deeply, narrowly concave border. Clypeus convex, 
the carina short and thick; anterior border nearly straight. Mandi- 
bles short, very thick and blunt, the blade without teeth. Frontal 
carinae broad at base; antennal grooves longer than scapes. Scapes 
extending a little more than half the distance from eyes to occipital 
corners. Club shorter than remainder of funiculus; funicular joints 
2-7 as long as broad. Eyes small and convex, located at sides of head 
at anterior third. Pronotum transverse, the sides extended into 
blunt cones. Promesonotal impression feeble. Mesonotum flat an- 
teriorly; with a narrow transverse depression before the basal margin, 
which is somewhat elevated; declivous behind. Epinotum broadly 
depressed at base, the spines very stout, triangular and strongly 
diverging. Petiolar node in profile wedge-shaped; from above twice 
as broad as long. Postpetiole three times as broad as the petiole, 
conical at sides. Gaster elliptical. Legs short, femora and tibiae 
thickened. 
Head subopaque, coarsely striate, striae extending over occiput; 
clypeus with several coarse punctures anteriorly. Mandibles sub- 
opaque; coarsely, sparsely punctate. Thorax subopaque with 
transverse, interrupted rugae. Epinotum sublucid, with a few fine 
transverse striae. Petiole and postpetiole closely, finely punctate. 
Gaster finely punctate, sublucid. Legs shining. Head, antennae, 
body, and legs with abundant long, rather stiff pile.
