Epipharyngeal sclerites: in bees; a pair of strap-like pieces extending backward from the two sides of the base of epipharynx: see hypopharyngeal sclerites.

Epipharynx: an organ, probably of taste, attached to the inner surface of the labium and supposed to correspond to the palate of higher animals Epiglossa or epiglottis.

Epiphysis: a lappet-like process covering an excavation on the fore tibia of many Lepidoptera.

Epipleural: the deflexed or inflexed portions of the elytra, immediately beneath the edge: the inflexed portions of the p.r.o.notum are sometimes called prothoracic epipleura: as generally used, the term is incorrectly applied to the entire bent under margin of the elytra.

Epipleural fold: the raised lower edge of the epipleura: see hypomera.

Epiploon: see caul.

Epipygium: the dorsal arch of the last abdominal segment.

Episternites: the upper pair of corneous appendages forming the ovipositor in gra.s.shoppers.

Episternum: the anterior and larger lateral thoracic sclerite between the sternum and notum.

Epistoma -is: the lower face between the mouth and eyes: that sclerite immediately behind or above the labrum, whether it be clypeus or an intermediate piece: in Diptera, that part of the face between the front and the labrum; the oral margin and an indefinite s.p.a.ce immediately contiguous thereto and so = peristoma: in Odonata; = clypeus: = hypostoma.

Epithelium: the layer of cells which covers a surface or lines a cavity.

Epizoa: insects that infest the body surface of animals.

Epizootic: living or parasitic on animals from the outside or on the surface.

Epomiae: the elevated margin of an oblique furrow in the propleurae for the reception of the front femora; Hymenoptera.

Epupillate: an ocellate spot included by a colored ring, but dest.i.tute of a pupil or central spot.

Equal: of the same length, size or shape: the superfices when they are without inequalities.

Equitant: laminated: folding one upon the other.

Erect: standing upright; not necessarily perpendicular.

Erectile: capable of being erected; applied to an appendage, a hair or other process, or to any tissue which may be distended and made rigid.

Erecto-patent: the wings of Hesperids when at rest; primaries erect, secondaries horizontal.

Eremochaetus: Diptera in which there is a general absence of bristles.

Ergatandrous: applied to ants with worker-like males.

Ergatogynous: applied to ants with worker-like females.

Ergatoid: s.e.xually capable, wingless ants, resembling workers.

Ericeticolous: living in poor, sandy or gravelly places.

Eroded -sus: gnawed; a margin with irregular teeth and emarginations.

Eruca: broadly a larva: more specifically a caterpillar.

Eruciform: like a caterpillar in form or appearance.

Erucivorous: a feeder on caterpillars; said of parasites.

Erythrinus: red; nearly arterial blood-red: carmine, a little diluted.

Erythrinus: deep brick-red, tending to blood-red [vermilion with a little Indian red].

Escutcheon: the scutellum in Coleoptera.

Essential character: see specific character.

Ethology: see ecology.

Eucephalous: with a well-developed head, bearing the normal appendages: applied to certain dipterous larvae.

Eucone: a compound eye in which the individual ocelli have crystalline cones see acone.

Euorthoptera: the Orthoptera excluding the Dermaptera.

Euplexoptera: with beautifully folded wings: an ordinal term applied to the ear-wigs.

Eous or -eus: as a suffix, indicates the possession of the quality of the stem word: e.g. membraneous, like a membrane in texture.

Eutracheata: applied to articulates which, like the insects, have a well-developed tracheal system.

Ev.a.g.i.n.ate: extruded by eversion; turned inside out when extruded.

Ev.a.g.i.n.ation: an extrusion formed by eversion or turning inside out.

Evanescent: disappearing; becoming gradually less.

Eversible: capable of being turned inside out.

Evident: easily seen or recognized.

Ex: prefix = A and E as privatives: also means from or out of.
