Laevis -igatus: smooth, shining and without elevations: said of a surface. Lamella: a thin plate or leaf-like process. Lamellate: antennae with the club formed of closely opposed leaf-like surfaces, the concealed surfaces set with sensory pits. Lamellicornia: those beetles in which the antennae terminate in a lamellate or leaf-like club. Lamelliform: made up of or resembling leaves, blades or lamellae. Lamina -ae: a chitinous plate or plates. Lamina externa: the paraglossa. Lamina interna: the ligula. Lamina subgenitalis: the sub-genital plate; q.v.: in roaches the 7th ventral plate of females and 9th ventral plate of males. Lamina supra-analis: = supra-anal plate. Laminate: formed of thin, flat layers or leaves. Laminato-carinate: with an elevated ridge or keel, formed of thin plates. Laminiform: layer-like: having the appearance or made up of lamina. Lana: wool: the long hair on the abdomen of some Lepidoptera. Lanate -atus: woolly: covered with dense, fine, long hairs, so distinct that they may be separated. Lanceolate: lance- or spear-shaped: oblong and tapering to the end. Lanceolate cell: in Hymenoptera (ort.); - 2d anal (Comst.). Lancet: indiscriminately applied to any piercing mouth structure. Lanuginose -us: with long, curled hair dispersed over the surface: see crinitus. Lanugo: slender single hairs. Laparostict: that series of lamellicorn beetles in which the abdominal spiracles are situated on the connecting membrane between the dorsal and ventral rings. Lapidicolous: living under deeply imbedded stones. Larva: the second stage of insect development; comes from the egg or ovum, grows, and according to its kind, changes to a pupa or chrysalis or to an imago; bears various names in the different orders: see nymph; caterpillar slug; maggot; grub. Larvarium: a tube or case made by a larva as a shelter or retreat. Larvatae: asked; applied to coarctate and obtect pupae. Larvina: a maggot: a dipterous larva without distinct head or legs. Larvule: applied to early stages of Ephemerid larvae when they appear to have no developed respiratory, circulatory or nervous systems. Lashed: eyes that have a more or less complete fringe of stiff hairs or bristles at the orbits. Lasureus: a very dark blue [French blue with some black]. Laterad: toward the side and away from the median line. Lateral: relating, pertaining or attached to the side. Lateral areas: in Hymenoptera; on the metanotum, the three spaces between the median and lateral long carinae; the upper is the external or first lateral basal area; the second is the external or central lateral area; the third is the middle, internal, apical or third lateral area. Lateral bristles: in Diptera; situated at or near the lateral margins of the abdominal segments. Lateral carinae: in Orthoptera; on the head, extend downward from the front margin of the eyes: on prothorax extend along each lateral margin of the dorsum.
