8me Tribu PLAGIOLEPISII. 
Genre BrachymyrmMex, Mayr. 
1. Brachymyrmex Heeri, Forel, var. obscurior, n. var. 
(No. 57a a 57 0). 
82. Ne differe de la forme typique que par sa couleur 
brunatre et par ses ailes légérement enfumées de brunitre. La 
pubescence est peut étre aussi légérement plus forte. 
Cette forme se distingue du B. patagonicus, Mayr, par 
labsence des ocelles, par sa taille plus petite et par sa 
pilosité un peu plus abondante. Les scapes sont aussi 
un peu plus longs. 
(57). Moderately common in communities of a few 
hundreds at most. The formicarium is formed under a 
stone, or at the roots of grass and weeds, generally on 
open ground ; but if my hasty identifications are correct, 
the species ranges to the tops of the highest mountains. 
So far as I have observed, the formicarium consists 
only of one or two simple chambers, with a short con- 
necting passage. The ants are moderately active, less 
so than allied forms. They are sometimes beaten from 
foliage.
