Epicranial: relating or pertaining to the epicranium. Epicranial lobe: in caterpillars, the lateral, superior convex lobe of the head. Epicranial plate: in some larvae a plate-like structure forming the epicranium. Epicranial suture: the line of junction of the two procephalic lobes. Epicranium: the upper part of the head from the front to the neck: often used to include front, vertex and genae:= calva. Epideme: see articulatory epideme. Epiderma -is: the cellular layer of the skin, underlying and secreting the cuticula: incorrectly applied to the outer skin or cuticle. Epidermata: abnormal excrescences or outgrowths from the skin. Epididymis: the convoluted efferent ducts, massed at the posterior part of the testes. Epigastrium: the first entire ventral sclerite of the abdomen. Epigenesis: the doctrine of growth from an undifferentiated germ, as opposed to preformation, which implies development from already existing rudiments. Epigenetic: the period after the union of the male and female elements, during which organs are forming. Epiglossa: = epipharynx; q.v. Epiglottis: = epipharynx; q.v. Epilabrum: a sclerite at each side of the labrum: specifically applied in myriapods. Epilobe: of mentum in Carabidae, really corresponds to a partially divided ligula: a lateral appendage of a bilobed mentum. Epimera -eron: the posterior lateral thoracic sclerites; usually small, narrow or triangular. Epiopticon: the second ganglionic swelling of the optic tract: see opticon. Epipharyngeal: belonging or relating to the epipharynx. 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 pronotum 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. Epiplooen: see caul. Epipygium: the dorsal arch of the last abdominal segment. Episternites: the upper pair of corneous appendages forming the ovipositor in grasshoppers. 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 space immediately contiguous thereto and so = peristoma: in Odonata; = clypeus: = hypostoma.
