Family: a division of classification including a number of genera agreeing in one or a set of characters and so closely related that they are apparently descended from one stem: opinionative and indicated by the termination idae. Farctus: fully filled. Farinaceous: mealy: applied to powdery looking wings and surfaces. Farinose: dotted with many single, flour-like spots: mealy. Fascia: a transverse band or broad line; it is common when it crosses both wings or wing covers. Fasciate: banded transversely. Fascicle -ulus: a bundle of hair, threads or fibres. Fasciculate: bundled; clustered as in a bundle; tufted: a surface when covered with bundles of long hair. Fastigiate: flat-topped and of equal height: also applied to elytra that extend a little beyond the abdomen. Fastigium: Orthoptera; the extreme point or front of vertex. Fat-body: is the mass of oil or fat cells found, especially in larvae, surrounding the alimentary canal and some other internal organs. Fatiscent: with cracks, crevices or openings. Fauna: the assemblage of animals inhabiting a region or country. Favose: with large deep holes, like the cells of a honeycomb. Favus: a cell like that of a honeycomb. Fecula: the excrement of insects. Fecundation: the making fertile; as an egg by a spermatozooen. Feeler: commonly applied to antennae; q.v. Feelers: tactile organs: the term is usually applied to the antennae, but sometimes to the palpi, as mouth-feelers. Feet: the legs or organs of locomotion; one pair attached to each thoracic segment; composed of coxa, trochanter, femur, tibia and tarsus only; plural of foot; q.v. Female: designated by "O+" the astronomical sign for Venus: that sex in which the ova are developed. {Scanner's comment: The sign for Venus being an orthogonal cross or plus sign hanging vertically below a circle.} Femina: the female, or belonging to that sex. Femorate -us: with abnormal or unusually developed femora or thighs. Femoro-tibial: pertaining to both femur and tibia or to the articulation between them. Femur -ora: the thigh: usually the stoutest segment of the leg, articulated to the body through trochanter and coxa and bearing the tibia at its distal end: in Coccidae and quite commonly, the femur and trochanter are considered as one, for measuring purposes. Fenestra: a window; a transparent glassy spot or mark; a pellucid mark in a vein: a small, pale, membranous area at the base of the antenna in roaches. Fenestrate: with transparent or window-like naked spots as in the wings of some Lepidoptera. Fenestrate membrane: of the compound eye is at the base of the ommatidia, at their junction with the optic nerve; see retina. Ferreous -eus: the metallic gray of polished iron. Ferrugineous -ous, -eus, -osus: rusty red-brown [Dragon's blood, but brighter]. Ferrugino-testaeeous: a rusty yellow brown: a mixture of rusty red with dull yellow brown.
