same length as the inner margin or a little longer, the apical 

 tooth curved, acute ; clypeus very narrow, with a short, square, 

 slightly-produced median lohe, and having a median, very short 

 carina or tubercle ; antennal carinae short, laminate, covering the 

 bases of the antennae ; antennae 12-jointed, the scape and flagellnm 

 slightly incrassate towards their apex ; eyes small, placed rather 

 to the front and well forward towards the anterior margin of the 

 head ; ocelli absent. Thorax broad, convex in front, compressed 

 posteriorly, the pro-meso- and meso-metauotal sutures both 

 distinct ; the basal portion of the metanotum short, not longer 

 than the apical portion, the latter obliquely truncate ; legs short 

 and stout, the intermediate and posterior tibiae with paired calcaria, 

 the anterior calcaria on all the tibiae simple, the posterior pectinate ; 

 the tibiae and the basal joint of the tarsi of intermediate legs 

 studded with spines. Pedicel one-jointed, the node convex in front, 

 concave posteriorly, viewed from the side cuneiform, thick at base, 

 with a dentiform process beneath ; abdomen rather massive, cylin- 

 drical, the basal segment anteriorly truncate, slightly concave, the 

 constriction between the basal two segments not well marked. 

 Two species only of this genus are known from within our limits.
