Part 10

Ante-furca: an internal forked process from the prosternum, to which muscles are attached.

Ante-humeral: relating to the space just before origin of wings.

Ante-humeral stripe: Odonata; a discolored stripe, approximately parallel to, but to the inner side of the humeral suture, q.v.

Antemedial line: = t. a. line, q.v.

Antemedian: Diptera; applied to leg-bristles situated before the middle.

Antenna -ae: two jointed, sensory organs, borne, one on each side of the head, commonly termed horns or feelers.

Antenna-cleaner: a fringed excavation on the interior base of the 1st segment of the anterior tarsi of Hymenoptera which, when covered by the movable process from the end of the tibia, forms an opening through which the antennae may be drawn: similar structures are on the fore tibiae of Carabid beetles: tarsal claws are also used by various insects to clean antennae.

Antennal appendage: in Mallophaga, a projecting process of the 1st or 3rd segment in the male.

Antennal formula: in Coccidae; made by enumerating the antennal joints in the order of their length, beginning with the longest 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.
