Odontomachus haematoda variety stanleyi ^HNS, new variety

Worker.-Length 7 to 8 mm. Distinctly smaller than the typical haematoda ^HNS, with a distinctly narrower head and the mandibles, antennae, thorax, legs, and gaster paler and reddish castaneous brown. In many specimens the cheeks, clypeus, antennal foveae, gula, and borders of the mandibles are yellowish. Petiole with longer and more uniformly slender spine. Sculpture of the head and thorax as in the typical hxmatoda, but with the gray pubescence on the gaster distinctly longer and more conspicuous. The sides of the head are much less smooth and shining than in the Neotropical subspecies insularis (Guerin) ^HNS, which is of the same size though paler in color.

Described from numerous specimens from two colonies taken at Stanleyville (Lang and Chapin). The cocoons are also distinctly paler than those of the typical haematoda ^HNS.
