Subcostal nervule: Lepidoptera, on secondaries:= media 1 (Comst.): s.c. 1 = radius 1 (Comst.); s.c. 2:= radius 2 (Comst.) s.c. 3 = radius 3 (Comst) s.c. 4 = radius 4 (Comst.) s.c. 5 = radius 5 (Comst.). Subcostal vein: in Diptera (Schiner), = 1st longitudinal vein (Meigen) radius 1 (Comst.): in Lepidoptera, runs from base, parallel to costa, to or beyond the middle, giving rise to branches which extend to the outer margin and thus = radius (Comst.). Sub-cristate: with a moderately elevated ridge or keel on pronotum, in Orthoptera. Subcutaneous: under the skin: applied to larvae that feed under the skin of animals or within the substance of a leaf. Sub-dorsal: the space between the dorsum and the stigmata. Sub-dorsal line: in caterpillars is to the side of the dorsal and between it and the lateral or, if there is an addorsal line, between that and the lateral. Sub-dorsal ridge: in slug caterpillars, extends longitudinally along the sub-dorsal row of abdominal tubercles. Sub-equal: similar, but not quite equal in size, form or other characters. Sub-eroded: wing margins when somewhat, but irregularly, indented. Sub-falcate: when a wing is only a little excavated below the apex. Subfamily: a division of classification containing a group of closely allied genera; different from other allied groups, yet not so as to make a family series: opinionative, and ending in -inae. Sub-fossorial: legs used in digging: yet not greatly modified. Sub-frontal: close to the front; immediately behind the front margin. Sub-fulcrum: a sclerite between mentum and palpiger: rarely present. Sub-fusiform: somewhat spindle-shaped. Subgalea: a maxillary sclerite or segment, attached to the stipes, and bearing the galea or outer lobe. Sub-geniculate: applied to antennae that are articulated from a short, thick scope. Subgenital lamina or plates: plates underlying the genital organs in Orthoptera. 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 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.).
