Interradiella. Fig. 3, bq 1 . 



A cross-vein between radiella and metacarpella. Rarely 

 present. 



Synonym: Transverse nervure of marginal cell Ashmead 1900. 

 Basella. Fig. 1, hgj 1 ; fig. 2, jhgj 1 ; fig. 3, hj 1 ; fig. 6, jgj 1 ; fig. 7, jj 1 ; fig. 4, jg. 



A cross-vein situated at about the anterior middle of the wing, 

 having its origin from subcosta or stigmella and terminating at 

 mediella. Present in Chalastogastra, Braconidae and a few other 

 groups. When the cross-vein is well towards apex of wings as in 

 figs. 5 and 8 it is considered to be intercubitella. It is not likely 

 that basella (jgj 1 , fig. 6) is homologous with intercubitella (kk\ 

 fig. 5).

 longitudinal vein from the anterior margin of the wing basad of 

 nervellus.

Discoidella. Figs. 1, 2, j l ts; fig. 5, ts; fig. 8, gs. 



The third apical longitudinal vein from the anterior margin 

 of the wing; often absent (figs. 3, 4, 6, 9, 11), but when present, 

 either forming a continuation of mediella from basella to the wing 

 margin (figs. 1, 2), or in the absence of basella beginning at ner- 

 vellus (fig. 8), or, in some instances, originating at a point on 

 nervellus (fig. 5).

 and submediella, or in some wings (figs. 1, 2) connecting discoid-
