1. Odontomachus rixosus View in CoL   HNS .

O. rufo-fuscus, femoribus pallide testaceis; margine interna mandibulorum subserrata, thorace transversim striato.

Worker. Length 4 1/2 lines. Reddish-brown: the coxae, trochanters and femora pale testaceous, the extreme base, and apex of the latter, darker; the mandibles with two blunt teeth at their apex, the outer tooth notched on one side, forming a second tooth; the inner edge slightly serrated, having only four or five minute teeth; the prominence between the sulcations on the anterior part of the head, obliquely striated; the striations crossing the sulcations, but terminating opposite the hinder margin of the eyes; the depression on the sides of the head striated, the striation becoming obsolete at the sides of the head. The thorax transversely striated, the metathorax most strongly so. The scale of the abdomen conical, terminating above in an acute spine; the abdomen very smooth and shining, the apex pale testaceous.

Hab. Singapore.

This species bears a strong resemblance to the type of the genus, O. haematodes, a South American insect; but that species has the head shorter, and the vertex delicately striated; the antennae are shorter, the joints shorter: specimens which I consider to be identical with the present species, are in the collection at the British Museum, from Birmah and Singapore.
