lows: Uruguay (Montevideo), Argentina (La Plata, Salta, 

 Tandil — very abundant, Juarez, Rosario, Cordoba, Buenos 

 Ayres) and Brazil (Bahia). The Brazilian record ought, 

 perhaps, to be considered doubtful. 



This species probably has its closest ally in steindachneri. 

 See the discussion, concerning beliicosus, following the de- 

 scription of baeri. 



Hudson (vide supra) states that this species is common in 

 La Plata. He says that it usually builds its nest in a depres- 

 sion on the surface of the ground under the shelter of a bush 

 and that the nest is dome-shaped and consists of "small 

 sticks, thorns and leaves bitten into extremely minute 

 pieces."

Type. — Handlirsch described this species from two workers 

 and three males — from Brazil (Ypanema) and Mexico (Cuer- 

 navaca). These specimens are in the collection of the k. k. 

 Hofmusuem at Vienna. 



Pile rather short and of medium texture. Malar space medium. 

 Dorsum of thorax yellow, zvithotit black interalar ba^id ; pleura dark . 

 Abdomen of females dark, except the third dorsal segment yellow. 

 Abdomen of male dark, with third and fourth dorsal segments yellow. 

 Head of females black. Legs black. Hind tibia" of male convex with- 

 out and thickly covered with short hair. 



Queen. — I have seen one queen, 21 mm. in length and with colora- 

 tion exactly like that of the worker, in the collection of the American 

 Entomological Society. 



Worker. Head. — With black pile only. Malar space slightly shorter 

 than its width at apex, about one-fifth as long as eye. Clypeus coarsely, 

 but for most part very sparsely, punctate, a large part of the disc ap- 

 pearing mostly smooth. Third antennal segment distinctly longer than 

 the fifth, the fifth longer than the fourth. 



Thorax. — Dorsum entirely covered with yellow pile, except for a 

 small bare area on the center of the disc, this yellow pile extending 

 down onto the mesopleura is somewhat below the level of the bases of
