J . Mandibles simple ; cljpeus distinctly separated from the 

 face, convex; face smooth, subquadrate ; vertex and temples 

 smooth and shining. Antennae 28-jointed, third and fourth 

 joints subequal, joints five to eight diminishing gradually, in the 

 funicle the first fifteen joints are cylindrical. Thorax shining, 

 epimeral furrows crenulate throughout. Median segment with 

 the apical carina of the basal area complete, areola and external 

 arese smooth ; petiolar and adjacent arese, the apical two-thirds 

 of the spiracular arese, and the dentiparal arese subrugulose ;

rugse in front of the coxa. Petiole without a subbasal tooth, but 

 the spii'acular area prominent ; spiracles well behind the middle ; 

 abdomen shining, smooth. Areolet (text-fig. 2) pentagonal, second 

 abscissa of the radius shorter than either of the transverse cubital 

 nervures, distance between the recurrent nervure and the second 

 transverse cubital nervxu'e equal to nearly half the length of the 

 latter nervure ; second recurrent nervure only feebly bent in the

Very distinct in the neuration from the larger species of the
