 but close to it. 



Submarginal area: of secondaries, lies between the costal margin and the ist 

 strong vein. 



Submarginal cells: in Hytncnoptcra (Norton) = radial cells (Comst.) : in 

 Diptera (Will.); = radial 3 (Comst.). 



Submarginal nervure: in Hymciwptera (Nort.) ; the irregular line of veins 

 extending on the whole parallel with the outer margin ; composed in part of 

 media i, 2, 3 and 4, the medial cross vein and cubitus i (Comst.). 



Submedian cells: in Hymenoptera (Pack.) ; 1st ^ cubital -\- cubital i (Comst.) ; 

 2d = medial 3 (Comst.); 3d = 2d medial 2 (Comst.). 



Submedian vein: in Odonata, = cubitus (Comst.); in Lepidoptcra. = ist 

 anal (Comst.), runs from base of primaries to the hind angle, close to the 

 inner margin and is v. i of the numerical series. 



Submental: pertaining to the sub-mentum. 



Submental peduncle: in Colcoptcra, the prolonged portion of the gula support-

Subnodal sector: in Odonata, ^radial sector (Comst.). 



Sub-nymph: applied to the resting or pupal stage of $ Coccidcr ; also to a 

 supernumerary stage before the formation of the pupa, and thus = pseudo-
