1 (4) . Cu2 one cell long 2 



2 (3). Usually more than 14 postnodal cells. Ac near the level of the first antenodals. 

 Mia arising six to eight cells before the stigma. Cui is six to seven cells long. 

 West Africa. (Fig. 130.) Chlorocnemis Selys, 1863 



3 (2). Less than 10 postnodal cells. Ac about midway between the antenodals.

 4(1). Cu-2 reduced to a cross-vein or lacking, not projecting beyond MA 5 



5 (18). A not reduced to Ac, but extending beyond 6 



6 (13). A ending in MA, and not in Cu on the posterior side of the quadrangle, nor 

 in the hind margin of the wing before MxA. No "cubito-anal" cross-veins before 

 Ac. That edge of the stigma along the margin of the wing as great as that along 

 Ri. The quadrangle practically uniform in width 7
