Gemmiparous: applied to that form of asexual reproduction where new individuals arise as buds from the germ body of the parent. Gena -ae: the cheeks; includes that portion of the head on each side below the eyes, and extends to the gular suture: in Odonata the area between the eyes and clypeus and mouth parts: in Diptera the space between the lower border of the eye and oral margin, merging into face at front and limited by the occipital margin behind. Genal bristles: Diptera; are on the cheeks near lower corner of eye. Generalized: primitive: containing in combination characters that are separated and specialized in other forms. Generation: used as the equivalent of brood; q.v. Genicular arc: Orthoptera; a curved dark marking on the posterior knee-joint. Geniculate: knee jointed: abruptly bent in an obtuse angle. Geniculum: a little knee or bend. Genital armature: all the processes concerned in copulation. Genital hamule: a little hook or plate covering the anal cavity of the male: the supra-anal or genital hook: in Lepidoptera, the uncut: in Odonata, in the plural, one or two pairs of lateral processes of the male genitalia on the ventral surface of the second abdominal segment. Genital hook: = genital hamule. Genitalia: the external organs of generation with all appendages. Genital lobes: in Odonata, a pair of-backward and downwardly directed processes from the 2d abdominal segment, between which the vesicle of the penis lies. Genital papilla: in some Smynthurids, a tubercular elevation upon which the genital aperture opens. Genital spike: the sheath of penis which, in male Diaspinae takes the form of a long mucronate spike. Genital tuft: in Lepidoptera; an expansible tuft of fine hair believed to be scent-producing. Genital valve: Odonata; a chitinous piece on each side of the ovipositor, derived from the sternum of abdominal segment 9: probably = outer pair of gonapophyses. Genoholotype: the species on which a genus is founded, whether unique or one of a series, specifically named as generic type by the author. Genolectotype: the one species of a series selected as the type of the genus in which the describer of the genus placed it, subsequent to the description. Genosyntype: one of a series of species upon which a genus is founded, no one species being mentioned as type. Genus: knee; the joint between femur and tibia. Genus: an assemblage of species agreeing in some one character or series of characters; usually considered as arbitrary and opinionative, though some consider it a natural assemblage. Geometrid: larva which, when walking, alternately elevate and straighten the middle of their body: opposed to rectigrade; q.v. Geodephagous: = adephagous; q.v. Geodromica: terrestrial Heteroptera in which the antennae are not concealed. Geophilous: living on the ground: species that live on the surface or come freely into contact with it.
