1. Brachymyrmex Heeri, Forel, var. obscurior , n. var. (No. 57 a a 57 l).

[[ worker ]] [[ queen ]] [[ male ]] Ne differe de la forme typique que par sa couleur brunatre et par sea ailes legerement enfumees de brunatre. La pubescence est peut etre aussi legerement plus forte.

Cette forme se distingue du B. patagonicus, Mayr , ' par l´absence des ocelles, par sa taille plus petite et par sa pilosite 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 connecting passage. The ants are moderately active, less so than allied forms. They are sometimes beaten from foliage.

(57 a). Wallibou (leeward); thickets near the seashore. Oct. 6 th. Community of several hundreds under a stone. Sandy ground.

(57 b). Cumberland (leeward); open valley near the sea-level., Male and female found together under a stone (not copulated). Oct. 8 th.

(57 c). Islet fronting Chateaubelais Bay (leeward), Oct. 31 st. Rocky ground, thickets near sea-level. Workers found scattered under stones.

(57 e). Soufriere Volcano, 2500 ft. Sept. Scrubby growth found in moss, & c,

(57 f). Wallilobo Valley (leeward), Nov. 8 th; open hill-side, 500 ft. A female referred to this species, found alone under sod on a rock.

(57 g). Bowwood Valley, near Kingstown, 800 ft. Oct. 15 th. Second growth-, beaten from branches.

(57 h). Not noted. Doubtfully referred to this species.

(57 i). Windward side; open sandy valley of the Dry River, near the sea. Jan. 2 nd. From two nests under stones. The species is common in this vicinity.

(57 j). Same locality and date as (57 i). An unusually large community under a stone. The winged females and males (especially the males) were very numerous.

(57 k). Bank near seashore, between Georgetown and the Dry River (windward). Jan. 3 rd. Nest at the roots of grass.
