Cell: any s.p.a.ce between or bounded by veins: in the Comstock system the cells derive their names from the vein forming the Tupper margin: e.g. all just below the radius are radial cells; and they are numbered from the base outward, as radial 1, 2, etc.: the living unit; protoplasm differentiated into cytoplasm and nucleus, from which units all but the lowest plants and animals are developed by division and consequent increase into a multicellular condition: a compartment or division of a nest or honey-comb.
Cellule: a portion of a wing included between veins; usually applied to a small area completely inclosed, rarely to inters.p.a.ces where no closed area is formed.
Cenchrus -rib: minute, often white marks, or membranous s.p.a.ces on the metanotum of some Hymenoptera.
Cenogonous: producing young at one time oviparously, at another viviparously as in plant-lice.
Centimeter: abb. Cm.: = .01 meter = .394 inch; 2.54 Cm. = one inch.
Centrad: toward the centre or interior.
Central foveola: see median foveola.
Centrolecithal: applied to eggs in which the food yolk is central.
Centrosome: a spherical body that appears outside the nucleus of a cell.
Cephalad: toward the head, along the central line of the body.
Cephalic: belonging or attached to the head; directed toward the head.
Cephalic bristles: Diptera; specialized bristles occurring on the head.
Cephalic foramen: the posterior or occipital foramen of head through which the dorsal vessel, oesophagus, salivary ducts and ventral nerve cords pa.s.s from head to prothorax.
Cephalization: concentration toward the head.
Cephalomere: one of the head segments of an arthropod.
Cephalophragm: a v-shaped part.i.tion which divides the head of some Orthoptera, into an anterior and posterior chamber.
Cephalon: the head.
Cephalosome: the head as one of the three regions.
Cephalotheca: the head covering in the pupal stage.
Cephalotheca: the united head and thorax of arachnids and crustacea {Scanner's comment: nowadays this term is used little if at all. It does not seem ever to have been popular. Instead the terms cephalothorax or prosoma are widely used.} : that portion of an obtect pupa covering head and thorax: the anterior segments of larva that have no obviously separated head.
Cerago: bee-bread.
Ceratheca or Ceratotheca: that portion of the pupal sh.e.l.l that envelops the antenna.
Cerci: two lateral a.n.a.l appendages; usually short, jointed, antenna-like, developed from the eleventh abdominal segment of the embryo; sometimes unjointed and specialized into forceps or other processes.
Cercopoda: jointed foot-like appendages of the last abdominal segment; also applied like cerci.
Cercus: see cerci.
Cerebellum: has been applied to the sub-esophageal ganglion.
Cerebrum: the supra-oesophageal ganglion.
Cernuous: bent: with the apex bent downward.
Cervical: relating or belonging to the neck.
Cervical foramen: in coleopterous larvae - occipital foramen.

Ceryinus: reddish, deer-gray [pale cadmium yellow and Indian red].
Cervix: the upper part of the neck; = crag: in Diptera; that part of the occiput lying over the junction of the head, i.e. between the vertex and neck.
Cespitose: matted together.
Chaetophorous: applied to bristle-bearing flies.
