Fusiform: spindle-shaped: tapering gradually to each end.

Fusulus: = spinneret, q.v.

Gales: the outer lobe of the maxilla, usually two-jointed, often hood-like, subject to great modifications in Hymenoptera and Diptera, and forms the coiled tongue in Lepidoptera.

Galeotheca: that part of the pupal case that covers the gales.

Gall: an abnormal swelling or excrescence on a plant, produced by an insect: = cecidium.

Gallicolous: dwellers in galls, whether as producers or inquilines.

Gallivorous: feeding upon galls or gall tissue.

Gamogenesis: reproduction through fertilization: see agamogenesis.

Ganglion -ia: a nerve centre composed of a cell mass and fibres: the white disc-like bodies connected by a double cord, lying above the ventral surface within the body and forming the centre of the nervous system.

Gasterotheca: that part of the pupa case that covers the abdomen.

Gastric: of or belonging to the belly or to the stomach.

Gastric caeca: = caecum; q.v.

Gastro-coeli: a pair of usually transverse lateral pits near the base of the second abdominal tergite in some Hymenoptera.

Gastro-ileal folds: occur in some insects at the junction of the chylific ventricle with the ileum and serve as a valve.

Gastrula: that embryonic stage resembling a sac, with an outer layer of epiblastic cells and an inner layer of hypoblastic cells.

Gastrulation: the process of forming a gastrula.

Gathering hairs: the soft, flattened, often hooked hairs on the tongue of bees and other Hymenoptera; = hooked hairs.

Gelatinous: of a jelly-like texture or consistency: viscid.

Geminate: arranged in pairs composed of two similar parts: doubled.

Gemmate -us: marked with metallic or bright colored spots.

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.
