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-a.n.a.lis: = supra-a.n.a.l 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 a.n.a.l (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 s.p.a.ces 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.

Lateral foveolae: in Orthoptera: foveate depressions on the margins of the vertex near the front border of the eye.

Lateral line: in caterpillars is at the margin of the dorsum between sub-dorsal and supra-stigmatal line.

Lateral lobe: of the labium in Odonata, corresponds to the paraglossa with palpiger and palpus (Gerstaecker) or, more probably, to the palpus alone (Butler).

Lateral lobes: the deflexed portions of p.r.o.notum that cover the sides of pro-thorax in many Orthoptera: in certain Hymenoptera, lie on each side of the parapsidal furrows of mesoscutum and = scapulae.
