Brachius. Fig. 1, T'U'S; fig. 2, TWIT 1 ; figs. 5, 6, 8, 9, 10, T^U 1 . 



The continuation of submedius from nervulus to end of vein 

 which is usually at or near the margin of the wing, and forming 

 the posterior boundary of the first brachial cell. Apparently no 

 writers have so divided submedius.

Nervulus. Figs. 1, 2, 9, 10, TT 1 ; figs. 5, 6, 7, 8, J'T 1 . 



The cross-vein connecting meclius and submedius and forming 

 the apical boundary of the submedian cell; in some Chalasto- 

 gastra there is a more or less spurious cross-vein basad of 

 nervulus which divides the submedian cell into two cells and 

 which has been termed the prenervulus q. v.

Prenervulus. (Not illustrated.) 



A more or less spurious cross-vein occurring in the submedian 

 cell of some Chalastogastra, usually near its middle, which li;i- 

 its anterior end on medius and rarely is long enough to touch 

 submedius.
