and base of the meta-pleurse shining and impunctate ; the 

 latter with a curved keel on the innerside of the spiracle, 

 beyond which the segment is shagreened. The base of 

 the petiole depressed ; the depression margined, the 

 margin continued shortly beyond it as blunt keels ; the 

 apex of the segment obscurely punctured. 



The areolet is petiolated to near the bottom, where 

 there is formed a minute cellule, not much wider than the 

 transverse cubital nervure ; its outer nervure is faint, and 

 is interstitial with the recurrent.
