the crown. Mareja species are similar in form to the larger species of 
Graphocephala Van Duzee, but can be separated readily from all other similar 
genera by the scleritelike lobe of the proepimeron and by the very broad and 
convex anterior margins of the antennal ledges in lateral view. 
I examined the female holotype of Tettigonia viridescens Walker. My records 
warrant nothing more than placing the species in Mareja. 
My identification of Tetiigonia anceps Fowler is based on an examination of 
the male lectotype. The female lectotype of Tettigonia obtusior Fowler was 
studied, and is the basis for the present identification of that species. 
I compared the female lectotype of Tettigonia urbana Stal with the present 
illustration of the crown and pronotum (fig. 797a). I follow Schréder 
(1959a:499 in placing 7. limbaticollis Stal in synonymy.
