Postnervellus. Fig. 4, gz. 



A cross-vein extending from mediella or cubitella towards the 

 posterior margin of the wing in certain Braconidae. 



Synonym: Postnervellus Gahan 1915. 



C. THE WINGS WITH FEW VEINS. 



In the Chalcidoidea and certain other groups the venation is so 

 greatly reduced as to cause systematists to use a different termi- 

 nology. ' To explain this terminology, which is certainly most 

 convenient to the systematist, it is desirable to consider these 

 wings separately. Under the term "nervure sous costale" Andre 

 1879 classifies the entire normal Chalcidid venation, but he also 

 explains and synonymizes the terms for the various parts used. 

 However, the terminology proposed by Howard in 1881 has been 

 more generally used by systematists and is adopted here. 



Submarginal. Fig. 11, AB. 



The basal portion of the longitudinal vein posterior to the ante- 

 rior margin of the wing in Hymenoptera in which the venation is 

 reduced to one longitudinal vein. This vein occupies the same 

 position as the subcosta of ^the more generalized wings and is 

 perhaps homologous with it.

Marginal. Fig. 11, BC. 



That portion of the longitudinal vein which lies along the ante- 

 rior margin of the wing, basad of the branch (stigmal) which 

 extends obliquely into the body of the wing from the anterior mar- 

 gin in the Hymenoptera in which the venation is reduced to a 

 longitudinal vein. This vein occupies the same position as the 

 stigma in the more generalized wings and is perhaps homologous 

 with it.
