WILLIAM MORTON WHEELER. 



a distinct club ; all the joints except the first and last broader than 

 long; joints 2-4 transverse, nearly twice as broad as long. 

 Thorax slender, narrower than the head ; the pro- and mesonotum 

 forming an even convexity above, without promesonotal suture ; 

 the mesoepinotal impression distinct but shallow; the epinotum 

 in profile rising steeply for a short distance in front, then becoming 

 straight and horizontal in the middle and gradually passing into 

 the short sloping declivity; the metasternal angles rather large, 

 lamellate and rounded. Seen from above the epinotum has a 

 ridge on each side, bounding a large median longitudinal im- 

 pression for the accomodation of the petiole. The latter is nearly 

 as high as long, the peduncle shorter than the node, which rises 

 rather abruptly in front and is rounded above, with a posterior 

 slope like the anterior. Seen from above the node is somewhat 

 broader than long. The ventral surface of the peduncle bears a 

 small, blunt tooth anteriorly. Postpetiole lower than the petiole 

 and about half again as broad, with bluntly subangular sides, the 

 node very convex above and inclined somewhat forward. There 

 is a small acute tooth at the anterior end on the ventral side. 

 Gaster elliptical, its anterior border feebly excavated. Legs 

 rather slender. 



Mandibles subopaque, densely striated; remainder of body 

 very smooth and shining, with minute, sparse, piligerous punc- 

 tures. Cheeks, mesopleurse and sides of epinotum longitudinally 

 rugulose. 



Hairs long, erect or suberect, golden yellow, somewhat bristly 

 and rather abundant on the body, legs and antennae; pubescence 

 absent, except on the funiculi. 



Yellowish red; mandibles, funiculi, the posterior half of the 

 first segment of the gaster and the sutures of the thorax and 

 pedicel, brown; tip of gaster yellowish. 



Female. Length nearly 4 mm. 



Very similar to the worker, with larger eyes and distinct ocelli. 

 Thorax as broad as the head through the eyes, the mesonotum 

 convex and rounded above, subhexagonal, as broad as long. 

 Epinotum sloping, without distinct base and declivity. Gaster 

 as in the worker. Wings with a distinct discoidal cell, a single 

 elongate cubital cell and the submarginal cell open at the tip.
