Psyche 
[February 
pronotum; petiolar pedicel subtly punctate, nodes of petiole 
and postpetiole smooth above, obliquely striate at sides. Gaster 
and appendages finely punctate. 
Pilosity pale yellow, fine and erect, rather sparse on head, 
body and appendages. 
Brownish red, the gaster darker and the legs lighter than 
the rest. 
Sierra Maestra, July, 1902, Alt. 4500-5000 ft. 
Type. Cat. No. 26497 U. S. N. M. 
Described from four workers. 
M. bruneri is most closely related to M. affinis Mann, and 
like it, superficially resembles a Tetramorium. It differs from 
affinis in its smaller size, the much shorter epinotal spines (in 
affinis these are fully as long as the petiolar pedicel), in the 
petiolar node rising less abruptly from the pedicel and in sculp- 
ture and coloration. 
Macromischa (Macromischa) violacea^ new species. 
Worker. Length 4.5 mm. 
Head, excluding mandibles, one-sixth longer than broad, 
sides very slightly convex, posterior corners broadly rounded, 
border nearly straight. Mandibles with five rather strong teeth. 
Clypeus nearly flat, its anterior border straight at middle. Eyes 
large and convex, situated at middle of sides of head. Antennal 
scapes not quite attaining occipital corners; funicular joints 
2-8 scarcely broader than long; club shorter than remainder of 
funiculus. Thorax and epinotum very robust, as broad in front 
as behind and only feebly and narrowly constricted at sides be- 
tween pro- and meso thorax; no sutures discernible. Epinotal 
spines moderately thick, slightly curved, shorter than their dis- 
tance apart at base. Peduncle of petiole nearly twice as long as 
the node, which rises from it abruptly and, in profile, is higher 
than long, with nearly straight anterior and posterior surfaces 
and slightly convex dorsum, and from above transversely suboval. 
Postpetiole campanulate and broader than long. Femora and 
tibiae rather strongly incrassate.
