MANN: THE ANTS OF BRAZIL. 429 



79. Pheidolc {Elasmopheidoh) aherrans 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 tliroughout, 

 agreeing in this respect with a series from Buenos Ayres (Silvestri 

 coll.) in the Wheeler collection. 



80. Pheidole (Pheidole) ginlelmi-muUeri 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 subhicid, 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.
