1903.] NATURAL SCIEN'CES OF PHILADELPHIA. 2d5 



elevated anterior pronotal border. Pleurae compressed; dorsum flat- 

 tened and without mesoepinotal constrictions. Epinotal spines small, 

 conical, distinctly longer and further apart than broad at their bases. 

 Petiole short, hardly Ih times as long as broad, sides of node convex 

 when seen from above and much broader than the peduncle; in profile 

 the node is high and very thick with an evenly rounded summit, very 

 steep and concave anterior, and very abrupt posterior declivity; ven- 

 tral tooth rather large, blunt . Postpetiole twice as broad as the petiole, 

 distinctly broader than long, transversely elliptical from above, with 

 rounded anterior angles. Gaster of the usual shape. 



Mandibles and clypeus subopaque, the former longitudinally striated 

 and with a few coarse punctures, the latter longitudinally rugose. 

 Head opaque throughout, evenly and densely punctate except along 

 the sides of the frontal region, where there are a few delicate longi- 

 tudinal rugse. Thorax, petiole and postpetiole opaque, densely 

 punctate. Gaster smooth and shining. 



Hairs white, moderately numerous, clavate on crown of head, 

 thorax and abdomen ; erect on head and thorax, more reclinate on the 

 pedicel and gaster; minute, inconspicuous and appressed on the an- 

 tennae and legs. 



Whole body, even the anterior portion of the gaster, golden-yellow, 

 except the antennal club which is blackened. 



Female (dealated). — Length 2.5 mm. 



Head opaque, densely punctate; cheeks and whole preocellar region 

 irregularly longitudinally rugulose, the postocellar region and posterior 

 angles more reticulate. Thorax opaque, densely punctate ; mesonotum 

 and scutellum wath very faint, parallel, longitudinal rugse. Epinotal 

 spines very short and stout, regularly conical, not as far apart as they 

 are broad at the base. Petiole and postpetiole like those of the worker, 

 but the latter segment fully twice as broad as long. Both segments of 

 the pedicel densely punctate, opaque, except the dorsal surfaces of 

 the nodes which are somewhat smooth and shining. Body brownish- 

 yellow, legs pale-yellow. Antennal club, wing-insertions, sides and 

 posterior border of first gastric segment, a broad transverse band on 

 the second gastric segment and the tip of the gaster, dark-brown. 

 Pilosity like that of the worker. 



Type locality: Austin and McNeil (Travis county), Tex. 



This small species lives in and on the ground. At Austin I have 

 occasionally seen a few workers running about on the dry gravelly 

 hill-slopes exposed to the sun. At McNeil I took a few dozen workers 

 and a dealated queen, which were inhabiting a small spherical chan:ber
