 the galea or outer lobe. 



Sub-geniculate: applied to antenna; that are articulated from a short, thick 

 scape. 



Subgenital lamina or plates: plates underlying the genital organs in Orth- 

 optera. 



Subgenus: a division within a genus, based upon a character not sufficient 

 for generic separation ; opinionative. 



Subglossa: in Odonata; a sclerite between the two halves of the mentum 

 (Graber) : is really the true mentum. 



Sub-imago: sometimes applied as = nymph: that stage in Ephemerids just 

 after emergence from the pupa and before the final molt during flight : that 

 stage in the development of insects with free pupa when the insect is fully

Submargin -al: an imaginary portion of a surface outside of the disk and 

 within the margin : a line is submarginal when it is well within the margin ; 

 but close to it. 



Submarginal area: of secondaries, lies between the costal margin and the 1st 

 strong vein. 



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

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



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

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

 media 1, 2, 3 and 4, the medial cross vein and cubitus 1 (Comst.). 



Submedian cells: in Hymenoptera (Pack.) ; 1st = cubital + cubital 1 (Comst.) ; 

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



Submedian vein: in Odonata, = cubitus (Comst.); in Lepidoptera, = 1st 

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

 inner margin and is v. 1 of the numerical series. 



Submental: pertaining to the sub-mentum. 



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

 ing the mentum. 



Submentum: the basal sclerite of the labium, by means of which it is at- 

 tached to the head. 



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



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

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

 pupa. 



Sub-ocellate: an ocellate spot that is blind or without a pupil.

Sub-oesophageal ganglion: situated in the head below the oesophagus, formed 

 by a union of the posterior three primitive head ganglia. 



Sub-order: a division of an order higher than a family, based on a character 

 common to a large series of species; e. g., the Homoptera and Heteropu-ra
