12. Leptothorax bradleyi sp. nov. 

 Worker. Length 2.6 mm. 



Head rather large, subreetangular, a little longer than broad, with straight, 

 parallel sides and feebly excised posterior border. Eyes rather small, at the middle 

 of the sides of the head. Mandibles and clypeus moderately convex, the latter with 

 straight, entire anterior border. Frontal area small and indistinct. Antennae 

 11-jointed; scapes reaching half way between the eyes and the posterior corners of 

 the head; funiculi with a 3-jointed club; first funicular joint as long as the three 

 succeeding joints together; joints 2-6 much broader than long, joint 7 as long as 

 broad; terminal joint longer than the two penultinate joinls together. Thorax 

 rather robust, narrower than the head, broader in front than behind, but as high 

 behind as in front, with flattened dorsal and lateral surfaces and rather angular 

 humeri, without any traces of a mesoepinotal constriction. Epinotal spines stout, 

 as long as broad at their bases, laterally compressed, suddenly tapering at their 

 tips, directed backward and slightly upward, further apart at their bases than long. 

 Petiole from above about 1| times as long as broad, pyriform, with rounded sides; 

 its node in profile with feebly concave anterior and decidedly convex posterior slopes, 

 meeting with a distinct transverse ridge, the lower border in profile feebly concave 

 and with a small, compressed anterior tooth. Postpetiole from above transversely 

 elliptical, slightly broader than the petiole, slightly broader than long, in profile 

 smaller than the petiole, as long as high, with evenly rounded, convex node. Gaster 

 elongate elliptical, its sides rather straight, its anterior border excised in the middle. 

 Legs stout, with incrassated femora.
