middle of the anterior margin ; antennal carinae moderately long, 

 placed in the middle of the face, on a raised vertical tubercle which 

 is longer than broad, the carinae somewhat close together and 

 slightly convergent posteriorly. Thorax entirely unarmed and the 

 form as given in the characters of the genus ;" legs robust, tibiae 

 cylindrical, smooth, constricted for a third of their length from base. 

 Node of the pedicel cuneate, the upper margin very thin and arched, 

 bearing at its lateral angles an acute tooth ; abdomen globose. 



$ . Similar to the ; larger ; wings hyaline with a brownish 

 tint ; pronotum short, vertical ; mesonotum ample, convex ; 

 scutellum transverse, very convex and gibbous ; postscutellum 

 sunk in a deep wide furrow between the scutellum and the

 divergently forward, basal portion of metanotum posteriorly trans- 

 versely margined, the lateral angles with short erect points, apical 

 portion concave ; legs slender, tibiae cylindrical and without spines. 

 Node of pedicel high, biconvex, surmounted at the lateral angles 

 with short erect spines, the upper margin of the node between 

 the two spines straight, the sides of the node with a lateral acute 

 tooth very short and placed low down on the node; abdomen 

 globose.
