Internal veins: in Lepidoptera, from one to three in number, run free from base to outer margin near hind angle; never branched;1a to is in the numerical series: = anal veins (Comst.).
Interneural: between the nerves (or veins) of wings.
Interno-mandibular: applied to one of the pairs of salivary glands in bees, situated at the inner side of base of mandible.
Internomedian: in Orthoptera; = cubitus (Comst.); q.v.
Interocular: between the eyes.
Interplical: lying between folds; specifically applied to the alternate ridges and grooves in anal area of secondaries of Orthoptera.
Interposed sectors: in Odonata; the shorter longitudinal veins occurring in the wings of some species between the chief veins; = supplementary sectors. Interrupted: broken in continuity, but with the tips of the broken parts in a right line with each other.
Intersegmental: = interarticular; q.v.
Interspace: Coleopteran; the plane surface between elytral striae: Lepidoptera spaces between wing veins not included in closed cells.
Interspaceal: occurring in the interspaces between two wing veins or two elytral striae.
