Explanation of Terms Used in Entomology Part 81

Sub-parallel: nearly parallel.

Sub-primary sub-ventral tubercle: on the thoracic and abdominal segments of caterpillars; sub-ventral, posterior, not present in the primitive first stage; it is VI of the abdomen, V of the thorax: constant.

Sub-sellate: nearly like or approaching the form of a saddle.

Sub-servate: denticulate.

Subspecies: a well-marked form of a species differing from the type in some character of color or maculation which is recognizable but does not prevent a fertile union: an indefinite and opinionative division.

Subspiracular line: in caterpillars, margins the spiracles inferiorly.

Substigmatal: that portion of the marginal cell below the stigma, in bees: = 1st radial 1 (Comst.): applied to a line in caterpillars = subspiracular.

Sub-teres: nearly but not quite cylindrical.

Subtile -is: slightly; feebly; small; pretty; graceful.

Subtriangular s.p.a.ce: = internal triangle: see triangle.

Subtus: beneath; at the under surface.

Subulate: awl-shaped: linear at base, attenuate at tip.

Subulicornia: with awl-shaped antennae; applied to a combination of Odonata and Ephemerida.

Subuliform: formed like an awl: = subulate.

Sub-ventral line: in caterpillars, extends along the sides just above the base of the feet at lie edge between lateral and ventral.

Sub-ventral ridge: in slug caterpillars extends longitudinally along the sub-ventral series of abdominal tubercles.

Sub-ventral s.p.a.ce: in slug caterpillars is the area on each side, between the lateral ridge and the lower edge of the body, and contains the spiracles.

Succincti: those chrysalids of b.u.t.terflies which are held in place by a silken cord pa.s.sing around the body: see suspensi.

Succineous: resembling amber in color or appearance.

Sucking pump: in sucking insects, a thick-walled muscular enlargement of the oesophagus that serves to draw up the liquid food = pharyngeal pump.

Sucking spears: the mandibles and maxillae of Hemerobiid larvae, used for puncturing prey and sucking its juices.

Sucking stomach: a thin-walled muscular pouch connected with the end of the oesophagus; serves as a food reservoir and is not commonly present except in some Lepidoptera.

Suctoria: an ordinal term proposed for fleas.

Suctorial: adapted for sucking: see haustellate.

Suctorial vesicles: bladder-like structures connected with the oesophagus in mosquitoes supposed to a.s.sist in blood-sucking; but this is disputed.

Suffused: clouded or obscured by a darker color.

Suffusion: a clouding, or a spreading of one shade over another.

Sulca: grooves, furrows or channels: plural of sulcus.

Sulcated: grooved; furrowed with broad, concave, parallel impressed lines.

Sulciform: resembling a sulcus.

Sulcus: a furrow or groove: a groove-like excavation.

Sulphureous -eus: bright, sulphur yellow [chrome lemon].

Superans: exceeding in size and length.

Superciliary: placed above the eyes.

Supercilium: an arched line over an ocellate spot.

Super-family: a division of cla.s.sification less than an order, including a series of family groups more closely related to each other than to similar groups within the order: opinionative and ending in oidea: sometimes hardly different from suborder; but lower than suborder when both terms are employed.

Superficies: the upper surface.

Supericornia: those Heteroptera having the antenna inserted on the upper parts of the sides of the head; e.g. Coreidae: see infericornia.

Superior wings: the primaries; q.v.

Superlinguae: the lateral pair of organs of hypo-pharynx in Thysanura.

Superlingual segment: the fifth segment of head.

Superne: denotes all those parts belonging to the upper surface.

Supernumerary: additional or added cells, veins or other structures.

Supernumerary segment: in Cecidomyidae, between the head and first thoracic segment.

Super-order: a group of allied orders, like the Linnaean Neuroptera.

Superposed: placed one above the other, as the frontal tufts in some moths.

Supplementary sectors: interposed sectors; q.v.

Suppression: the non-development of a part normally present.

Supra-: over; above.

Supra-alar bristles: in Diptera, are situated, one on the post-alar callus, one on the alar frenum, the third on the edge of the supra-alar depression.
