Odontomachus assiniensis variety aterrimus , new variety

Worker.-Length about 10 mm. Differing from the variety furvior in being entirely jet black, including the appendages. The sculpture of the head and thorax is distinctly finer than in any of the other forms of the species, so that the surface is more shining. The legs are smoother and also more shining, especially the femora, than in any of the other forms. The unsculptured surfaces of the body, viz., the antennal foveae, the mesopleurae, lower portion of epinotum, and the gaster have a distinct blue opalescence. The longitudinal groove on the dorsal surface of the epinotum is continuous.

Described from a single specimen found in the stomach of a frog (Rana albolabris) from Niapu (Lang and Chapin).
