g in escaping from ooetheca, and later, in molting:
Heteroptera; a blister-like enlargement at the middle of the anterior
margin of the pro-thorax.

Ampulla-like: flask-shaped; applied to a vascular sac at base of
antennae which aids in the blood circulation of head and its
appendages.

Amygdaliform: almond-shaped.

Anabolic: the constructive change from food material to animal tissue:
see katabolic.

Anal: pertaining or attached to the last segment of the abdomen; the
point or angle of any wing or other appendage that is near to or at any
time reaches the tip of the abdomen.

Anal angle: on the secondaries is that angle nearest the end of the
abdomen when the wings are expanded: the angle between the inner
and outer margin of any wing; = hind angle of primaries.

Anal appendages: generally; applied to the external genital parts.

Anal area: Orthoptera and Neuroptera; the hinder or anal portion of a
wing within the anal vein = axillary area.

Anal cells: the spaces between the anal veins (Comst.): in Diptera,
anal cell (Will.), the space nearest the body, inclosed by the 5th and
6th veins sometimes called the third basal cell (Coq.) = 1st anal
(Comst.).

Anal field: Orthoptera; that area on the tegmina corresponding to the
anal area of the secondaries.

Anal filaments: see caudal setae.

Anal fork: applied to the cerci of Coleopterous larvae.

Anal foot: applied to the tip of the body in larval Chironomids, which
is modified to serve as a hold-fast.

Anal furrow: in wings, lies between the cubitus and 1st anal vein.

Anal glands: appendages of the alimentary canal, opening into it near
the posterior extremity, secreting either a lubricant, a silk-gum, or
some other specialized material.

Anal horns: in Collembola, are small processes borne on the last
abdominal segment.

Anal lobes: in Lecaniinae, a pair of small, triangular, hinged processes
forming a valve which covers the anal orifice.

Anal loop: Odonata; the loop formed by the angulations of 1st anal
vein.

Analogous: similar in function; but differing in origin and structure:
e.g. the wings of birds and insects: see homologous.

Anal operculum: the dorsal arch of the 10th abdominal segment; in
caterpillars = supra-anal plate, q.v.

Anal organs: Collembola; the two modified hairs arising
from a tubercle ventro-cephalad of the anus and
usually curving caudo-dorsad.

Anal orifice: see anus.

Anal papilla: Collembola; see anal tubercle.
