h scattered fulvous hairs; the wings fusco-hyaline, with a
dark fuscous stain occupying the marginal cell and traversing the course
of all the nervures; the legs with the femora much incrassated, the
posterior pair compressed beneath into a flattened process or keel.
Abdomen ovate, smooth, shining, and with a scattered fulvous pubescence;
the first node of the petiole rounded in front, narrowed and truncate
behind, with a large compressed tooth beneath; the second node
subglobose.

_Worker major._ Length 4 lines. Ferruginous, entirely smooth and
shining; the thorax, legs, and abdomen more or less obscure, the femora
being usually rufo-piceous; the mandibles striated with their margins
black. Thorax nearly flat above, very slightly convex with the sides
margined, the anterior margin slightly rounded, the lateral angles
produced into small acute spines; a deep strangulation at the base of
the metathorax, a little before which the lateral margins are produced
into an angular tooth, the metathorax with two short acute spines; the
femora thickly incrassate. Abdomen ovate.

_Hab._ Aru.

2. PODOMYRMA STRIATA. _P._ ferruginea; capite thoraceque
longitudinaliter striatis, femoribus valde incrassatis, basi
tenuissimis.

_Worker._ Length 3 lines. Rufo-ferruginous with the abdomen obscure,
becoming blackish at the apex, the head coarsely striated, with a
central portion from the insertion of the antennae to the hinder margin
of the vertex delicately so; the mandibles striated, with the teeth on
their inner margin black. Thorax rugose-striate, the anterior lateral
angles dentate, the metathorax without spines; the femora thickly
incrassate and greatly attenuated at their base. Abdomen ovate, smooth
and shining; the nodes of the petiole rugose.

_Hab._ Aru.

This species resembles _P. femorata_, but is easily distinguished by its
striated head and thorax; the latter is similarly flattened above and
margined at the sides; the femora are also thickened precisely as in
that species.

3. PODOMYRMA LAEVIFRONS. _P._ obscure ferruginea; capite abdomineque
laevissimis lucidisque; thorace longitudinaliter striato; femoribus medio
valde incrassatis, basi tenuissimis.

_Worker._ Length 2-1/2 lines. Head and abdomen smooth, shining black, in
some examples fusco-ferruginous; the antennae, legs, and thorax
ferruginous, the latter longitudinally striated; the thorax margined at
the sides, the disk slightly convex, the anterior margin sli
