Cornute -us: having horns or horn-like processes.
Corona: a crown or crown-like processes.
Coronate: with a crown-like tip or termination.
Coronet: a small crown or corona.
Coronula: a circle or semicircle of spines at the apex of the tibia.
Corpus: the body as a whole.
Corpus adiposum: the ma.s.s of fat tissue often found in larvae.
Corpuscle: a small cell; usually applied to blood cells.
Correlate: to bring together into relation or correspondence.
Correlated: derived from the same ancestral form: said of two or more features or qualities which bear a direct or an inverse relation to each other, but without implying a relation of cause and effect.
Correlative: of a correlated nature; see correlated.
Corrode: to eat away gradually, as by rust or decay.
Corrodentia: an ordinal term meaning gnawers: net-veined or wingless: mandibulate, mouth formed for gnawing; transformation incomplete; thorax incompletely agglutinated: = Psocoptera: includes Termitidae, Psocidae and Mallophaga. {Scanner's comment: These four groups are now placed in totally separate orders, and not families as these names imply}
Corrugated: wrinkled; with alternate ridges and channels.
Corselet: the thorax in Coleoptera.
Cortical: relating to the cortex or outer skin.
Corticinus: bark-like in sculpture, texture or color [vand.y.k.e brown].
Corvinus: crow-black; deep, shining black with a greenish l.u.s.tre.
Coryphatus: = capillatus.
Corysterium: an abdominal glandular structure in certain females, secreting a glutinous covering for the eggs.
Cosmopolitan: species that occur throughout most of the world.
Cosmotropical: species that occur throughout the tropics.
Costa: any elevated ridge that is rounded at its crest: the thickened anterior margin of any wing, but usually the primaries: in Comstock, the vein extending along the anterior margin of the wing from base to the point of junction with subcosta.
Costal area: the area behind costal vein; see also, costal field.
Costal cell: the area inclosed between the costal and sub-costal veins: in the plural, Comstock, are all the cells anteriorly margined by the costa; in Hymenoptera (Norton), includes the 1st, 2d and sub-costal; of Packard, the 3d costal = 2d radial 1, and radial 2: in Diptera (Will.), it is the 2d costal.
Costal field: Orthoptera; that region of the tegmina adjacent to the anterior margin or costa: = anterior field.
Costal fold: in the males of some Hesperidae, a membranous flap that may be opened to expose the androconia.
Costal margin: the anterior margin of a wing whether it is really costate or not.
Costal membrane: Hymenoptera; the surface of wing in front of costal vein.
Costal vein: Lepidoptera; runs close to and parallel with the costal margin, extending from base to the margin before the apex; always simple and often absent in the secondaries; is vein 12 of the numerical series on primaries; vein 8 on secondaries: = subcosta (Comst.).
Costate: ribbed; marked with elevated thickened lines.
Costula: Hymenoptera; a small ridge separating the externo-median meta-thoracic area into two parts.
Costulatus: less prominently ribbed than costate.
Cotyla: the articular pan; the cup or socket of a ball and socket joint.
Cotypes: are all the specimens before the describer when a species is named, no single one being selected as the type: the type in such case equals the sum of the cotypes: see paratype.
c.o.xa -ae: the basal segment of the leg, by means of which it is articulated to the body.
c.o.xal cavity: the opening or s.p.a.ce in which the c.o.xa articulates; in Coleoptera the cavity is open when the epimera do not extend to the sternum; closed or entire when the epimera reach the sternum or join medially as in Rhynchophora; the cavities are separated when the prosternum extends between them, confluent when it does not: see acetabulum.
c.o.xal glands: eversible glandular structures at base of legs; well developed in some Thysanurans, modified variously in higher orders.
c.o.xal stylets: short, leg-like, jointed appendages on the underside of the abdominal segments in Thysanura.
Crag: the neck: = cervix.
Cranium: the head or skull except the neck; sometimes limited to the fixed parts above the clypeo-frontal suture.
Cra.s.sus: thick; tumid.
Crateriform: like a shallow funnel or deep bowl.
Creber: closely set.
Cremaster: a stout spine, process or hooked area at the hind end of pupae in Lepidoptera.
Crenate: scalloped, with rounded teeth.
Crenulate: with small scallops, evenly rounded and rather deeply curved.
Crepitation: a crackling sound or the production of such as by discharge of vapor or "bombarding": a cracking or creaking.
Crepuscular: active or flying at dusk.
Crescentiform: like a lunule or crescent.
