basal part of the trochanter when it is two-jointed: in
Coleoptera, a piece often present on the outer side of and sometimes
movable on the coxa; also the small sclerite connecting the coxa with
the sternum in Dytiscidae: in Neuroptera and Trichoptera the
posterior separated part of the coxa: in Orthoptera, a narrow
longitudinal sclerite between mandible and gena.

Trochiformis: cylindro-conic.

Trochlea: the thickened base of the hind wings in Cicada: in
Trichoptera a small elliptical space at base of hind wing behind origin
of median vein.

Trochlearis: pulley-shaped; like a cylinder contracted medially.

Trochus: that part of an articulated body inserted between the joints.

Trophi: the mouth parts collectively, including the labrum: see buccal
appendages.

Trophobiosis: see Symbiosis.

Tropical: is that faunal region which covers the southern part of the
peninsula of Florida, the greater part of Central America, the lowlands
of southern Mexico south of the table land, and a narrow strip on

States.

Tropico-politan: occurring in all tropical regions.

Trumpets: breathing tubes of mosquito pupae.

Truncate: cut off squarely at tip.

Truncature: the truncation or point squarely cut off.

Truncus: the trunk or thorax.

Trunk: the thorax as a whole: the body.

Tryptic: acting like tripsin, the proteolytic ferment of the pancreatic
fluid.

Tube: a slender, hollow, cylindrical body: specifically applied to the
anal siphon or respiratory tube of mosquito larvae.

Tubercle: a little solid pimple or small chitinous button: really a ring,
which may or may not give rise to a seta.

Tubercles: on the thoracic and abdominal segments of caterpillars are
anterior trapezoidal; posterior trapezoidal; lateral; posterior stigmatal;
anterior stigmatal; sub-primary subventral; pedal and adventral: all
of which see.

Tubercula: an elevated triangular process at the anterior angle of the
thorax specifically in Hymenoptera.

Tuberculate -ose: formed like a tubercle: a surface covered with
tubercles.

Tubercule -ulum: a small tubercle.

Tuberculiform: shaped like a pimple or tubercle.

Tuberculose -ous: covered or set with tubercles.

Tubulifera: Hymenoptera, in which the terminal segments of abdomen
are retracted, but may be extended, tube-like: Thysanoptera in which
there is no ovipositor and the terminal segments of abdomen are
tubular.
