Part 154

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.

Tubulous -ose: formed like a tube: fistulous.

Tubulus: the slender, flexible abdominal segments forming the ovipositor in Diptera.

Tubus: a term used to designate the corneous base of a ligula: the sheath of the tongue.

Tumescence: a swelling or tumid enlargement: a puffed up area.

Tumescent: a little swollen or puffed up.

Tumid: swollen; enlarged; puffed up.

Tunica intima: the inner layer of the silk glands: an inner lining or membrane.

Tunica propria: a layer of epithelial cells and connective tissue lining the interior of the hind gut: the outer layer of the silk glands: a covering or investing membrane.

Tunicate: composed of concentric layers, enveloping one another: said of antennae when each successive joint is buried in the preceding funnel-shaped one.

Turbinate: top-shaped; nearly conical: differs from pyriform in being shorter and more suddenly attenuated at base: applied to an eye = pillared eye; q.v.

Turgid: swollen.

Turritus: towering: a surface rising cone-like.

Tylo: = tylus; q.v.

Tylus: the anterior central lobe of the head in Hemiptera.

Tympana: the ears in Orthoptera.

Tympanal: applied to organs covered with a tympanum or stretched membrane supposed to function as ears.

Tympanic spiracle: in Diptera, the thoracic spiracle at base of wing.

Tympanules: small openings covered by a membrane, having otoliths and serving as ears.
