125. Formica intrepida ^HNS. B.M.

Formica intrepida, Kirby ^HNS, Trans. Linn. Soc. xii. 477 [[worker]].

This species is probably the large form of the worker, the F. basalis ^HNS being the smaller form; this can only be decided by an examination of a community. F. intrepida ^HNS has the head, the basal joint of the antennae, and the abdomen black; the thorax, scale, and legs red; the scale is ovate and entire above; the extreme base of the scape is red; the inner margin of the mandibles is slightly rufo-piceous, and armed with six teeth; the length of the insect from the tip of the mandibles to the apex of the abdomen is 7 lines.
