TABLE OF GENERA. 



Frons with one or three keels or keels wanting 2. 



Frons with two distinct keels, slightly converging toward apex, much longer than 

 broad ; vertex before the eyes distinctly prominent; lateral margins of clypeus 

 only keeled at base. Wings as broad as long, broadly rounded at apex, with 

 a contiguous series of transverse veins between the apex of clavus and the 

 transverse vein of costal area, the costal area of normal breadth ; the interior 

 vein of the coi ium forked belore the middle. 



Wings vitreous ; posterior tibiaj with three spines G. i. Miriza, Stal. 



Wings opaque ; posterior tibia; with four spines G. 2. Mindura, Stiil. 



2 Lateial margins of clypeus keeled 5-

Wings as broad as long, with a regular series of transverse veins towards apex; 



posterior tibife with two spines behind the middle.. .G. 3. Pricesa, Stal. 



Wings toward apex very gradually enlarged ; posterior tibire with three spines 



behind the middle G. 4. Ricania, Germar. 



3 Marginal area with very narrow transverse veins 4- 



Marginal area with normal transverse veins. 



Longitudinal veins of wings much forked, with two regular series of tran>verse 

 veins toward apex, joining the apical G. 5. Porchazia, A. et S. 



Longitudinal veins of wings rarely forked, witli twt) series of irregular transverse 

 veins, remote G. 6. Tarundia, Sial. 



4 Longitudinal veins rarely emitting a forked vein from base of areole, the fis: forkrd 



before the base ; transverse veins very rare G. 7. Armacia, .Stiil.
