and, on the vertex, almost obsolete, and interspersed with coarse, shallow punc- 

 tures. 



The occipital region is strongly infuscated and the femora are bright ferru- 

 ginous, except at the apical third, where they are black. The apical band on 

 the first gastric segment is narrow, though with a tendency to extend forward 

 as an obscure median line.

64b. PoDOMYRMA BASALis Smith, subsp. wooDFORDi, subsp. nov. 



Worker. Length 3.50-4.75 mm. 



Head quadrate, a little longer than broad, as broad in front as behind, sides 

 nearly straight, occipital border broadly and shallowly concave. Mandibles 

 with five stout teeth. Clypeus rather flat, anterior border nearly straight. 

 Frontal carinae very feeble posteriorly, little divergent, extending nearly to 

 occipital border. Antennal scapes stout, extending a little more than two 

 thirds the distance to occipital corners; funicular joints two to eight slightly 

 longer than broad; club shorter than remainder of funiculus, with the termina 1 

 joint as long as the two preceding joints together. Eyes large, little convex,

situated at sides of head posterior to middle. Pronotum depressed in front, 

 humeral angles broader at base than long, triangular, not very acute at tips. 

 Mesonotal region sloping. Basal portion of epinotum slightly convex, broadly 

 rounding into the declivity. Petiole from above about three times as long as 

 broad, subquadrate; in profile convex at middle, armed dorsoanteriorly with 

 a thick conical spine and anteroventrally with a broader, flat spine, rounded 

 at tip. Femora strongly incrassate, tibiae moderately so. 



Moderately shining. Mandibles coarsely striate. Clypeus with three 

 distinct and entire striae on either side and much feebler and shorter striae on 

 middle portion. Striae of head fine, entire, and longitudinal. Pronotum with 

 a series of nine longitudinal, and sHghtly sinuous costae, six of which extend 

 on to the mesonotum. Epinotum with a low, rounded ridge on either side. 

 Petiole with acute lateral carinae. Basal gastric segment with short striae at 

 middle of base.
