16. Marginal cell open along the front margin . . . . . . 17 



Marginal cell closed along the front margin

2-7 small, moniliform Rhynchacis Forster

19. Wings extending far beyond tip of abdomen . . Kleidotoma Westwood

Club of antennae 5-jointed Pentacrita Forster

22. Club of antennae 6-jointed Hexacola Forster 



(Type Kleidotoma hexatoma Thorns. = Hexacola picea Forst.) 



* Kieffer proposes this genus for my Kleidotoma americana, which, however, is a true Kleidotoma. I am probably 

 responsible for the Abba's error by describing through a lapsjis pennae the marginal cell as being closed, when it is really 

 more or less open along the fore margin.
