Basal. Figs. 1, 2, 5, 6, 7, 8, JJ 1 ; fig. 9, BG; fig. 10, JiF 1 . 



A transverse or oblique cross-vein at or about the middle of the

Recurrents. Figs. 1, 2, 5, 6, 8, 9, II 1 and (or) NN 1 . 



Cross-vein or veins separating the discoidal cells, having their 

 anterior end on cubitus and the posterior end of the first on dis- 

 coide'us and the posterior end of the second on subdiscoideus. In 

 some groups the first recurrent curves outward and forms with 

 the basal abscissa of cubitus, the discocubitus, q. v. (fig. 5, 1 1 K J ).
