b«t not very t'onvi-x; ocelli nilluT siiiall. MuiuliMi's small, l»ut wc11-<1i:vi1o|h-(J, 

 their oxternal hordors slightly .siiumto towards the hiiHe, ronvex at the ii\m; 

 apical and basal bonN-rs distinct, siibi'cjnal. tlu' fonncr with four sMbcqual 

 teeth, (^lyixuis larm*. convex, somewhat broader than lon^, sli>i;htly dejiressetl 

 or flattened iMisteriorly. I'Vont trnncated anteriorly, with a transvers*' crest 

 or carina separatin^j it from the preocellar space and connecting the frontal 

 carinae, which are prominent, n<>arly straight, sulijjarallcl and as far apart 

 as they are from the lateral borders of the head. l'o8teri<jrly each carina 

 curves for\vard medially to the eye as a distinct ridge and terminates opiK)8ite 

 its anterior end, thus enclosing a small, shallow, elliptical scrobe about the 

 base of the antenna. Antennae 12-jointed, scape very small, about twioo 

 as long as broad, first funicular joint also very small, broader than long, sub- 

 globular; second joint longer but also broader than long, the remaining nine 

 joints cylindrical, of equal breadth, distinctly longer than broad and gradu- 

 ally increasing in length distally; terminal joint nearly as long as the two 

 preceding joints together, with tapering and somewhat p>ointed tip. Thorax 

 long, narrower than the head through the eyes. Pronotum well-developed, 

 truncated in front; mesonotum and scutellum somewhat flattened above, 

 the former with distinct MavTian furrows, the latter with a j)ecuUar blunt, 

 spatulate spine on each side, slightly curved inward at its tip. Epinotum 

 longer than broad, subrectangular from above, its base horizontal and twice 

 as long as the vertical declivitj- into which it passes through an abrupt curve, 

 the sides of the declivity above and of the base coarsely and rather irregu- 

 larly mar^ate. Petiole with a short, stout peduncle anteriorly and a thick, 

 cuboidal node, which is a little longer than broad and sUghtly liigher in 

 front than behind, with tnmcated anterior and posterior and feebly rounded 

 dorsal and lateral surfaces. Seen in profile its ventral margin is slightly 

 bisinuate, with a small, triangular tooth at the anterior end of the peduncle. 

 Postpetiole distinctly broader than the petiole and broader than long, from 

 above transversely elliptical, in profile slightly truncated anteriorly, convex 

 and rounded above, its ventral border unarmed, nearlj- straight. Gaster 

 elongate elliptical, with straight anterior border and tapering tip. Genitalia 

 completel}' retracted, cerci apparently absent; pj'gidium and hyjx)pygium 

 short and pointed. Legs short, of the usual simple fonn, without the tibial 

 spines of the worker and female; spurs of the middle and hind tibiae simple, 

 blunt at the tip. Tarsal claws very small, strongly curved, nonpectinated. 

 Wings very short (4.5 mm.), with a well-developed discoidal cell, a single 

 cubital cell and the radial cell shghtly open at the tip. The radial cell is 

 large. Pterostigma well-developed and conspicuous 



Subopaque; mandibles opaque, longitudinally rugose and verj- finely 

 punctate. Head reticulate-rugose, the clj-peus more coarsely and trans- 

 versely. Front behind its anterior truncation with regular longitudinal rugae 

 converging to the anterior ocellus, .\ntennal scrobes less distinctly longi- 

 tudinally rugose. Upper surface of mesonotum and scuteUum and sides of 

 thorax sharply and regularly longitudinally rugose, with elongate, shallow
