Humeral angle: in Lepidoptera, that angle of the wings at the base of costa, near the point of attachment to the body: in Coleopteran, the outer anterior angle of elytra: in Orthoptera, the obtusely rounded angle formed by the deflection of the sides of the pronotum from the dorsal.
Humeral bristles: in Diptera, are situated on the humeral callus.
Humeral callus: in Diptera, is a rounded callus forming the anterior superior angle of the mesothorax.
Humeral carina: in Coleoptera, an elevated ridge or keel on the outer anterior angle of elytra.
Humeral cross-vein: (Comst.); extends between the costa and subcosta close to base.
Humeralis: Coleopteran; when the elytral has an angulated projecting margin at base.
Humeral stripe: in Odonata, covers the humeral suture.
Humeral suture: in Odonata, runs from just in front the base of the fore-wing to the edge of the median coxa, separating the mesepisternum from the mesepimeron.
Humeral veins: in Lepidoptera, secondary veins on posterior wings of Lasiocampids, developed to strengthen the humeral angle.
Humerus: the shoulder: in Coleopteran; the basal exterior angle of elytra: in Diptera, the anterior superior angles of the mesothorax: in Orthoptera, the femur of the fore-leg: in Hymenoptera, applied to the sub-costal vein in some groups.
Humid: applied to regions in which the normal rainfall is sufficient to produce ordinary farm crops without irrigation: see arid.
Hyacinthine: the purple blue of the hyacinth [between mauve and lilac].
Hyaline: vitreous: transparent or partially so.
Hyaloplasm: the clear, semi-fluid material between the meshes of the cell reticulum.

Hydradephaga; -ous: applied to aquatic, predatory pentamerous beetles with filiform antennae: see adephagous.
Hydro: relating to water: a combining form used as a prefix.
Hydrolysis: the chemical decomposition of a compound by water, causing formation of a new compound.
Hydrophilous: applied to species living in low, damp places.
Hymen: a thin plane membrane serving as a partition.
Hymenoptera: membrane-winged: an ordinal term applied to insects with four membranous wings with few veins, the anterior usually larger than the posterior; mouth mandibulate; head free; thorax agglutinate, transformations complete.
