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 Ephemerida 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 colored but yet retains its pupal position.
Sub-labrum: =epipharynx; q.v.
Sublingual: beneath the tongue; applied to a pair of salivary glands in bees.
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 Hymenoptera (Norton) = radial cells (Comst.): in Diptera (Will.); = radial 3 (Comst.).
Submarginal nervure: in Hymenoptera (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.
