st and
bracketing together those of the same length.

Antennal fossa -w: grooves or cavities in which antennae are located
or concealed: = a. grooves: antennary fossa.

Antennal fovea: Diptera; a groove or grooves in the middle of the face
as though for the lodgment of the antennae; bounded on the sides by
the facial ridges.

Antennal foveolae: Orthoptera; the pits between frontal costa and
lateral carinae, in which the antennae are inserted.

Antennal grooves: see antennal fossa.

Antennal lobes: of brain, see deuto-cerebrum.

Antennal organs: in Collembola are sensory structures on the distal
segment.

Antennal process: Diptera; the frontal protuberance upon which the
antennae are inserted.

Antennal sclerite: see annulus antennalis.

Antennal segment: the second or deutocerebral segment of head.

Antennary fossa: see antennal fossa.

Antennary furrow: in Mallophaga, grooves on the under side of the
head in which the antennae lie.

Antenniferous: bearing antennae.

Antenniform: made up like, or having the appearance of antennae.

Antennule: a small antennae or feeler-like process.

Antenodal cells: Odonata; in Agrionidae the cells included between the
short sector (M 4 Comst.) and the upper sector of the triangle (Cu 1,
Comst.), and between the quadrilateral (or quadrangle) and the vein
descending from the nodus.

Antenodal cross veins: Odonata; extend between costa and sub-costa,
and between sub-costa and media, from the base to the nodus,
forming the ante-nodal or ante-cubital cells: = ante-cubital.

Antenodal costal spaces: Odonata; the cells between costa and
subcosta, from the base to the nodus: = ante-cubitals.

Anteocular: the region just before the eye; specifically applied in
Collembola to a peculiar structure of undefined function situated in
front of the eyes: = prostemmatic.

Antepectus: the lower surface of the prothorax.

Antepenultimate: the last but two.

Anterior: in front; before; in Dip., that face of the leg which is visible
from the front when the leg is laterally extended and bristles on that
face are anterior.

Anterior branch of third vein, in Diptera (Will.), = radius 4 (Comst.).

Anterior field: Orthoptera; of tegmina, see costal field.

Anterior intercalary vein: Diptera; = media 2 (Comst.); of Loew =
discoidal vein.

Anterior lamina: Odonata; the anterior sternal border of abdominal
segment 2, modified to form the front margin of the genital pocket.
