Part 94

Nearctic: temperate and arctic North America, including Greenland.

Nebula: a cloud: a vague, indefined, dusky shading.

Nebulous -ose: cloudy: without definite form or outline.

Neck: the slender connecting structure between head and thorax of such insects as have the head free: any contraction of the head at its juncture with the thorax.

Necrophagous: living in or on carrion.

Nectaries: honey-tubes, cornicles, siphuncles; q.v.

Nematid: thread-like.

Nematocera: = nemocera; q. A.

Nematocerous: with long, thread-like antenna.

Nemocera: Diptera with long, at least six-jointed antennae.

Nemoglossata: bees with a thread-like tongue.

Nemoricolous: living in open, sunny woods.

Neogeic: belonging to the Western Hemisphere or New World: see gerontogeic.

Neolepidoptera: all haustellate Lepidoptera, except the generalized Micropterygidae; mandibles not functionally present; pupa incomplete or obtect: see paleolepidoptera and protolepidoptera.

Neoteinic: applied to complemental females in Termites because, though reproductive, they retain some juvenile characters.

Neotropical: that part of the earth's surface embraced in the greater part of Mexico, West Indies and South America.

Neotype: a specimen identified with a species already described, and selected as a standard of reference where the original type or co-types are lost or destroyed.

Nephridia: tubular structures functioning as kidneys in Annelids, Mollusks, etc. and incorrectly used as = malpighian tubules; q.v.

Nepionic: that stage of development immediately succeeding the embryonic; proposed as a substitute for larval.

Nerinaeum: a ventral thoracic sclerite between the metasternum and posterior coxa in some Coleoptera.

Nerve: a thread-like structure, composed of delicate filaments whose function it is to transmit sensations or stimuli to or from a ganglion or from or to any part of the body or its appendages.

Nerves: sometimes used to = veins, in wing structures.

Nervi: belonging or referring to the nerves.

Nervulation: arrangement of the nerves: specifically applied to the arrangement of the chitinous framework of wings and thus= venation; q.v. Nervules or Nervures: the rod or vein-like structures supporting the membranes of wings and = veins and veinlets; q.v.

Nervuration: = nervulation and venation: q.v.

Neural canal: an incomplete tunnel on the floor of meso- and metathorax, formed by fusion of apodemes, serving for the reception and protection of the ventral nerve cord and for the attachment of muscles.

Neural groove: is that furrow in the primitive layer of the embryo in which the nerve cord is formed.

Neuration: = venation; q.v.
