mia | WHEELER — TWO NEW ANTS 31 
mesoépinotal constriction. Epinotum small, as long as broad, a litle 
more than two thirds as broad as the pronotum, with two small, slender, 
erect, pointed spines, about as long as broad at their bases, and directed 
upward and outward but not backward. The surface between them is 
concave and sloping, without a distinct angle between the epinotal base 
and declivity, bordered laterally by sharp ridges which run into the bases 
of the spines posteriorly. Petiole less than one and one half times as long 
as broad, slightly broader behind than in front, with rather straight sides. 
The node is entire and rather blunt at the summit, and in profile has a long, 
concave anterior, and short, abrupt posterior, slope. Postpetiole nearly 
one and one half times as broad as the petiole, and about one and one half 
times as broad as long, with bluntly angular sides. Gaster much smaller 
than the head, broadly elliptical, somewhat flattened. Legs rather long, 
femora somewhat incrassated. 
Smooth and shining, covered with sparse, piligerous punctures, which 
are most distinct on the head. Posterior border of clypeus, antennal fovese 
and space between the frontal carinz, finely and sharply longitudinally 
rugose. Mesonotum behind, epinotum and petiole, more opaque and finely 
punctate, rugulose-punctate on the sides. 
Hairs fulvous, erect, rather long, uneven, pointed, moderately abundant, 
covering the whole body, the legs and antenne, longest on the thorax, 
pedicel and gaster. Pubescence absent. 
Brownish ferruginous; head paler and more reddish; mandibles, cly- 
peus, frontal area, gaster and a very faint cloud on the middle of the head, 
reddish castaneous; legs more yellowish; antennal scapes not darker than 
the funicull. 
Described from a single specimen taken by Mr. C. L. Scott at Browns- 
ville, Texas. I have also seen two soldiers of this species from San Diego, 
Texas, in the Pergande Collection of the U.S. National Museum. 
This species is easily distinguished from Ph. absurda Forel of 
Central America by its somewhat smaller size, by the shape of the 
head (compare fig. 1, 6 and ce) and pronotum. In absurda the 
upper surface of the pronotum, when seen from the front, is not 
straight and transverse but convex and rounded. This form also 
has blunt but distinct teeth on the mentum, the gula is more con- 
vex, the petiolar node is distinctly sharper and more compressed 
antero-posteriorly, the sides of the postpetiole are more rounded, 
the epinotal spines are longer, blunter and more erect, that is, less 
deflected laterally, the antennal scapes are black, and the body, and 
especially the gaster, are much paler and more yellowish. None of 
these differences is, perhaps, great enough to prevent one from
