 than long, the brow rounded, the declivity vertical. Second joint of 

 petiole narrower than in the $ , hardly more than twice as wide as 

 long. Legs as in the $ . 



Antennae, mandibles, petiole and legs dark yellow, the rest of the 

 body brown, a little paler on the mesonotum. Wings with one closed

 long as the first joint of the flagellum, 2nd joint of flagellum nearly 

 twice as long as the 1st, all the joints longer than wide. The pronotum

$. Size variable, all forms occurring from ^ maj. to $ min. 

 Antennae 12-jointed, with a 3-jointed club. Olypeus large, sub- 

 triangular; mandibles short, thick and obtusely dentate. Frontal 

 carinae widely divergent posteriorly, the outer margin projecting so as 

 to form an indistinct scrobe in the largest $ $ . Eyes not large. 

 Pronotum flat above, produced anteriorly into a distinct neck, from 

 which and from the sides the dorsum is rather shortly delimited. 

 The pronotum is widest in front, narrowed and constricted behind. 

 Pro-mesonotal suture not distinctly defined dorsally. Mesonotum 

 strongly bi-tuberculate above and separated from the epinotum by a
