the thorax, petiole and postpetiole uniformly and densely punctate and 
opaque, except the epinotum, which is somewhat rugulose on the sides. 
The color is uniformly light ferruginous red, with slightly more yellowish 
gaster and legs. In some specimens the gaster is indistinctly infuscated 
posteriorly. 
The female measures 11-11.5 mm. and is colored like the worker, the 
wings are yellowish hyaline, with pale yellow veins and brown stigma. 
They are longer than in fulva. The female texana differs from the female 
fulva also in the shape of the head, which is narrower behind and therefore 
more elliptical, the eyes are more convex and the antenne distinctly longer, 
though their scapes do not reach so far beyond the posterior borders of the 
head as in the worker. The clypeus is finely rugulose-punctate and opaque 
as in fulua. The difference in the size of the postpetiole is even greater in 
the females of the two species. 
The male texana measures 4-5 mm. and is much paler than the male 
fulva, being reddish brown, with the head dark brown, the mandibles, an- 
tenne and legs light yellow, but the main difference is in the shape of the 
epinotum. The two protuberances of this region, representing the spines | 
of the worker, are much inflated and bluntly rectangular in profile in fulva, 
whereas in fezana they are much less swollen and acutely pointed. 
I have frequently taken this ant nesting in rather small colonies under 
stones in shady woods and ravines about Austin and New Braunfels, Texas. 
A very similar form, but slightly darker in the worker phase and tending — 
towards the variety described below, was collected in the Indian Garden 
on the Bright Angel Trail in the Grand Cafion, Arizona. Four workers 
received from Miss Anna Klaumann and taken at Douglas, Kansas (alt. 
900 ft.) are indistinguishable from Texan specimens. 
39. Aphenogaster texana Emery var. furvescens var. nov. 
Worker. Differing from the typical form only in color, which is reddish brown, 
with the gaster dark brown, except at the extreme base. In some specimens the 
head and nodes of the petiole and postpetiole are also distinctly infuscated. 
Female (deilated). Length: 7.5 mm. 
Like the worker, differing from the female texana in color, the body being rich 
brownish red, the basal half of the gaster, wing-insertions and a broad V-shaped 
blotch on the head, with its apex on the vertex and its two limbs running forward 
between the eyes and frontal carinz, blackish. 
Several workers and a single female from two localities in the Huachuca 
-Mts., Arizona, namely Miller Cafion, 5800 it. (Wheeler) and cunans 
Cafion, same altitude (W. M. Mann).
