ture, without dilated lateral margins or scrobes. Eyes very large 

 and prominent, ocelli only moderately large and rather far apart. 

 Antennae 13-jointed, with very short scapes. Thorax robust, broader 

 than the head, mesonotum with deep Mayrian furrows, scutellum 

 very convex. Petiole and gaster without fungiform appendages, 

 those on the postpetiole minute and vestigial. Wings as in the female. 



Glamyromyrmex beebei, sp. nov. (Fig. 2). 



Worker. (Fig. 2a and b). Length 1.5-2 mm. 



Head Ij times as long as broad, slightly broader behind than in 

 front, with deeply excised posterior and more feebly excised lateral 

 borders and broadly rounded anterior and posterior corners; behind 

 feebly convex, flattened in the middle and with sloping clypeus. 

 Mandibles convex, with about 8 slender and crowded teeth, which are 

 longest at the apex. Clypeus much broader than long, flattened, 

 with arcuately and deeply excised anterior and convex posterior border. 

 Antennal scapes tenuous at the base, somewhat thickened and fusi- 

 form in the middle. First funicular joint fully twice as long as broad 

 and much broader than the two succeeding joints; second joint longer 

 than broad, third as broad as long; fourth longer than broad and less 

 than I as long as the rather tapering terminal joint. Thorax much 

 narrower than the head, broadest through the pronotum, which is as 

 broad as long and evenly convex above, with minute but distinct 

 humeral angles. Pleurae rather flat. Mesonotum sloping to a feeble 

 constriction in front of the epinotum, the latter a little longer than 

 broad, its base marginate on the sides and passing into the subequal 

 declivity through a blunt angle. Spines laterally compressed, straight 

 and acute, as far apart at their bases as long, directed backward and 

 upward. Petiole fully twice as long as broad, pedunculate in front,, 

 with a low rounded node behind and with three spongiform appendages, 

 one forming a narrow longitudinal band on the median ventral surface, 

 the others a triangular mass on each side of the node. Postpetiole 

 transversely elliptical, distinctly broader than the petiole, with a 

 large spongiform mass enveloping its sides and ventral surface. 

 Gaster as large as the head, elliptical, with straight basal border and a 

 small fungiform mass on the anteroventral surface. Legs rather 

 slender. 



Smooth and shining; mandibles and head covered with minute, 

 sparse, piligerous punctures, the lateral borders of the head above
