caterpillars addorsal, anterior, always present, rarely united with II: it is
I of the abdominal series, la of the thorax (Dyar).
Antero: to the front; anteriorly.
Antero-dorsal: Diptera; applied to leg bristles at the meeting of anterior

tarsus is dilated and pubescent; the bees.
Anthracine -us: coal black; black with a bluish tinge.
Anti: over against; opposite; contrary: (prefix).

Antigeny: opposition or antagonism of the sexes; embracing all forms
of secondary sexual diversity.
Antipodal costal spaces: Odonata; the cells between costa and subcosta,
from the base to the modus; = antecubitals.
Antisquama: Diptera; the upper of the two which moves with the wings;
= antitegula; see also squama.
Antitegula: see antisquama.
Antlia: the spiral tongue or haustellum of Lepidoptera.
Antliata: insects with a sucking mouth; originally applied to
Lepidoptera and Diptera, later and more specifically to Diptera.
Antrorse -sum: directed toward the front.
Anus: the end of the digestive tract, through which the food remnants
are passed: the posterior part of the individual: specifically, in Coccidae,
a more or less circular opening on the dorsal surface of the pygidium,
varying in location as regards the circumgenital gland orifices: = anal
orifice.

Aorta: the anterior, narrow part of the heart, opening into the head.
Apex: that part of any joint or segment opposite the base by which it is
attached; that point of a wing furthest removed from base or at the end
of the costal area.
Aphaniptera: indistinctly winged; see Siphonaptera.
Aphideine: see aphidilutein.
Aphidilutein: a yellowish fluid found in plant lice, changed to a rich
violet by alkaline reagents.
Apical: at, near or pertaining to the apex; usually of a wing.
Apical area: see petiolar area.
Apical areas: apical cells in some Homoptera.
Apical cell: a cell near or at the apex of a wing; in Hymenoptera
(Norton) = medial (Comst.); outer apical cell = 2d medial 2 (Comst.);
inner apical cell = medial 3 (Comst.).
Apical cells or cellules: Trichoptera; the series of cells along the outer
margin of wing from pterostigma to arculus.
