Worker. Length 2.25-2.50 mm. 

 Female (dealated). Length 2.75 mm. 



Differing from the worker in the f oUowing characters : — the epinotal spines 

 are longer. The mesonotum and scuteUum are strongly striated longitudi- 

 nally. The striae on base of epinotum are stronger. The petiolar node in 

 profile is narrower and the peduncle a little longer. 



Male. Length L75 mm. 



Head, excluding the mandibles, a little broader than long, broadest behind, 

 with rounded corners and straight occipital border. Clypeus convex, anterior 

 border rounded. Mandibles large, their blades dentate. Antennae 14-jointed, 

 slender, thickened distally; scape thickened in front of middle, extending 

 two thirds the distance to occipital corners; funicular joints longer than broad; 

 terminal joint four times as long as broad and equal in length to the two pre- 

 ceding joints together. Eyes convex, located at about one fourth their length 

 from base of mandibles. Ocelli rather flat, situated in large foveae. Mesono- 

 tum with strong Mayrian furrows; elevated in front. Scutellum broader than 

 long, convex. Epinotum long, with subequal base and declivity. Petiolar 

 node low, the anterior surface shorter and more convex than the posterior; 

 peduncle as long as node, flattened above, sides margined. Postpetiole longer 

 than high, with a flattened anterior dorsal surface and short convex posterior 

 surface above, broader than long, broadest in front, with obtusely angulate 

 anterior corners. First gastric segment somewhat compressed dorsoventrally. 

 Legs long, not very slender. Wings with long and narrow stigma and a single 

 large cubital cell. 



Somewhat shining. Mandibles and clypeus finely punctate. Front of 

 head rugosely punctate, posterior portion of head and pronotum finely punc- 

 tate. Mesothorax and scutellum rugosely striolate; epinotum finely and 

 densely punctate. Petiole, postpetiole, gaster, and legs finely punctulate and 

 shining. 



Fine, long, and semirecumbent pale hairs throughout, but most abundant on 

 head, thorax, and gaster. 



Color yellowish brown; pronotum, thoracic pleurae, petiole, and postpetiole 

 lighter. Legs, clypeus, and antennae yellow. Wings hyaline, veins pale, 

 with dense pale hairs.

 species has a curious exudating habit. When the nest is disturbed the
