Stronger than those of front, finely margined, its medial surface 

 very short; dorsulum punctured anteriorly like pronotum, more

 lum more sparsely punctured, impressed; middle segment with 

 punctures about as strong as those on pronotum, deeply concave 

 medially, presenting two strongly convex surfaces, the sides at 

 base with a series of coarse folds, which are separated from simi- 

 lar folds on metapleurse by an elongate, narrow, raised, smooth area; 

 petiole longer than thorax, but hardly equalling the length of 

 head and thorax, the enlargement beginning behind middle, with 

 strong separated punctures, transversely depressed before apex, 

 the depression preceded by a dimple-like fovea; second dorsal
