Medial: referring to, or at the middle.
Medial cells: (Comst.), are anteriorly bounded by the media or its branches: in Hymenoptera (Mort.), includes median and cubital (Comst.)
Medial cross-vein: (Comst.), is between media 2 and 3.
Median 1: in Lepidoptera (Pack.), = media 2 (Comst.).
Median 2: in Lepidoptera (Pack.), = media 3 (Comst.).
Median 4: in Lepidoptera ( Pack.), = cubitus 2 (Comst.).
Median area: of wings in Orthoptera, lies between the radial and ulnar veins, radius and media (Comst.): of meta-thorax of Hymenoptera, is the middle of the dorsum, divided into three spaces or cells; 1st or basal area, 2d or Lipper median or areola; 3d or apical or petiolar area.
Median carina: Orthoptera; of head, is usually applied to a median dorsal carina, but has been also used for that which extends down the middle of front from the fastigium, and then = frontal costa: of prothorax, extends along the middle of pronotum.
Median cell: in Lepidoptera, is the closed area formed by a line extending from the end of subcostal to the end of the median veins, = radial (Comst.): in Hymenoptera, 1st median (Pack.), = medial (Comst.); 2d median (Pack.), - medial 4 (Comst.); 3d median (Pack.), = medial 2 (Comst.); 4th median (Pack.), = medial 1 (Comst.).
Median cross-veins: in Odonata; are those which cross median space.
