 the galea or outer lobe. 



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

 scape. 



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

 tcra. 



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

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 Hyincnoptera (Norton) = radial cells (Comst.) : in 

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



Submarginal nervure: in Hymenoptcra (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 Hyincnoptera (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 submentum. 



Submental peduncle: in Coleoptera, the prolonged portion of the gula sup- 

 porting 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 5 Coccida>; 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-ocular: beneath or below the eyes. 



Sub-03sophageal 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 Heteroptera 

 in the order of Hemiptera.
