Part 82

Lingua: the tongue; applied in Hymenoptera, to the ligula: in Lepidoptera and Diptera, to maxillary structures: has also been used for the hypopharynx, and that use might be adopted: a median organ of the hypopharynx in Apterygota.

Lingua spiralis: the spiral tongue of Lepidoptera: see glossa.

Linguiform: tongue-shaped: linear, with the extremities obtusely rounded.

Lingula: in Aleurodidae, a more or less slender tongue or strap-shaped organ, attached cephalad within the vasiform orifice: a term proposed by Leuckart for the ligula of the bees.

Lipochromus: without color.

Lipoptera: = Mallophaga; q.v.

Literate: ornamented with characters like letters.

Littoral: living along the sea-coast or in the shore debris: strictly, between tide marks.

Littoralia: Heteroptera that live in marshes.

Litura: an indistinct spot, paler at its margin.

Livid: yellowish gray with a violet tinge: greenish gray.

Lobate -us: divided by deep, undulating and successive incisions.

Lobe: any prominent rounded process or excrescence on a margin: specifically, the rounded, tooth-like processes on the margin of the pygidium of the Diaspinae: also applied to lateral expansions of the abdominal segments.

Lobes: of the maxilla; see galea (outer) and lacinia (inner): of the mentum in Coleoptera, are the lateral expansions shielding the base of the central organs.

Lobes of pronotum: in Orthoptera; the spaces or areas formed by three transverse impressions on the pronotum: that which borders the head is the anterior lobe, the hindmost is the posterior lobe, those intervening are the middle lobes.

Lobiform: shaped like a lobe or rounded process.

Lobulate: divided into, or with many small lobes or lobules.

Lobule: in Coccidae, one of the two distinct parts of which a lobe is sometimes composed.

Lobulus: the partly separated portion of the wings of some flies and of secondaries in some Hymenoptera: also used as = alula; q.v.

Lobus: of maxilla = galea; q.v.

Locomotion: organs of, are legs and wings.

Longicorn -ia: having the antennae as long or longer than the body; specifically the Cerambycid beetles.

Longitudinal: in the direction of the long axis.

Longitudinal veins: are those that extend lengthwise through the wing either directly from base or as branches of one that does start there: they are named or numbered, and differently in the different orders.

Loop: applied to that structure at base of innerside of primaries into which the frenulum of male moths is fitted: see retinaculum.

Looper: applied to geometrid and other caterpillars in which some or all the middle abdominal legs are wanting and which move by bringing tail to thorax and forming a loop of the intervening segments.

Lora: the chitinous bands connecting the submentum with the cardo of maxilla (Comst.): the submentum: small cords upon which the base of the proboscis is seated (Say): the anterior part of the genae at the edge of the mouth: the corneous processes to which the muscles flexing the mouth in certain Diptera are attached, and in that sense the palpifer of the maxilla: in Homoptera, the small sclerite at side of clypeus and front, extending laterally to the genae.

Lorum: in bees: the angular piece upon which the sub-mentum rests.
