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 subcostal 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].
