f the labium, by means of which it is
attached to the head.

Subnodal sector: in Odonata, = radial sector (Comst.).

Sub-nymph: applied to the resting or pupal stage of female Coccidae;
also to a supernumerary stage before the formation of the pupa, and
thus = pseudo-pupa.

Sub-ocellate: an ocellate spot that is blind or without a pupil.

Sub-ocular: beneath or below the eyes.

Sub-oesophageal ganglion: situated in the head below the
oesophagus, formed by a union of the posterior three primitive head
ganglia.

Sub-order: a division of an order higher than a family, based on a
character common to a large series of species; e.g. the Homoptera
and Heteroptera in the order of Hemiptera.

Sub-pedunculate: in Coleoptera, when the constriction between
pro- and meso-thorax is so great as to give the appearance of
a narrow waist.

Subreniform: a rounded spot or outline, below and sometimes
attached to the reniform spot in Catocala and some allied Noctuids.

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 space: = 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 space: in slug caterpillars is the area on e
