C

Caducous-us: deciduous; easily detached or shed.

Caecal tubes or pouches: sac, or blind tube-like structures surrounding the chylific ventricle at its junction with the crop, and secreting a digestive ferment.

Caec.u.m: a blind sac or tube-like structure serving as one of the caecal tubes or pouches: see coec.u.m.

Caelate: a surface with plane elevations of varying forms.

Caeruleus -eous: light sky-blue [between lavender and cobalt blue] = coeruleus.

Caerulescent: with a tinge of sky-blue.

Caesius -eous: a pale dull blue-gray [blue-gray].

Caespiticolous: frequenting or living in gra.s.sy pastures or lawns.

Calipers: the a.n.a.l forceps in Dermaptera.

Calli axillary: Odonata; thickenings at the bases of the wings; distinguished as anterior at the base of the costa, and posterior at the base of radius + medius and cubitus: = axillary calli.

Callosity: a thick swollen lump, harder than its surroundings: = callous: also a rather flattened elevation not necessarily harder than the surrounding tissue.

Callous: see callosity.

Callus: a small callosity.

Calva: a skull-cap: = epicranium, q.v.

Calx: the distal end of the tibia; the curving basal portion of the first tarsal joint.

Calyculate: applied to antennae, whose cup-shaped joints are so arranged as to fit one into the other.

Calypter: Diptera; the alula or squama when it covers the haltere.

Calyptra: a hood or cap; see alula.

Calyptrate: those flies that have aluke or membranous scales above the halteres.

Calyx: the cap or crown of the mushroom bodies of the procerebrum: see also egg-calyx.

Campanulate: bell-shaped: more or less ventricose at the base and a little recurved at the margin.

Campestral: applied to species inhabiting open fields.

Campodeiform: applied to larval forms which, in their early stages at Least, resemble Campodea: = lept.i.torm.

Canadian zone: is that part of the boreal region comprising the southern part of the great transcontinental coniferous forests of Canada, the northern parts of Maine, New Hampshire and Michigan, and a strip along the Pacific Coast reaching south to Cape Mendocino and the greater part of the high mountains of the United States and Mexico. In the east covers Green. Adirondack and Catskill Mountains and the higher mountains of Pennsylvania, West Virginia, Virginia, western North Carolina and eastern Tennessee. In the Rockies extends continuously from British Columbia to western Wyoming and in the Cascades from British Columbia to southern Oregon with a narrow interruption along the Columbia River.

Ca.n.a.liculate: channelled; longitudinally grooved, with a deeper concave line in the middle.

Cancellate: cross-barred: latticed: with longitudinal lines decussate by transverse lines.

Canescent: h.o.a.ry, with more white than gray.

Canine teeth: applied to the sharp and conical teeth of mandibles in predatory species: = dentes caninae.
