Part 113

Porcate: marked with raised longitudinal lines.

Pore: any small, round opening on the surface.

Poriferous: closely set with deep pittings or punctures.

Porose -us: with little round openings on the surface.

Porrect: stretched out forward: straightly prominent.

Post-: behind or after.

Post-alar callosities: rounded processes at the posterior lateral margin of the dorsum, in Diptera.

Post-alar callus: in Diptera, a rounded swelling between the root of the wing and the scutellum.

Post-alar membrane: the strip of membrane connecting the squamae with the scutellum.

Postal vein: in Hymenoptera, = costa (Comst.).

Post-annellus: in Hymenoptera, the 4th joint of antenna and 2d of flagellum.

Post antennal organs: in Collembola, oblong or ellipsoidal organs situated just caudad of the bases of the antenna.

Post-brachial: = pobrachial; q.v.

Post-cerebral: applied to that pair of salivary glands in bees, situated close to the posterior wall of the head.

Post-clypeus: in Odonata, the upper of the two parts into which the clypeus is divided: in Psocidae, a peculiar inflated structure behind the clypeus: in general, the posterior or upper part of clypeus when any line of demarcation exists: = supra-clypeus; nasus: afternose; paraclypeus: first clypeus; clypeus posterior.

Post-costa: = sub-costa (Comst.): in Odonata, = 1st anal vein (Comst.): in Trichoptera = anal.

Post-costal space: Odonata; the cell or cells lying posterior to the post-costa = anal cell (Comst.).

Post-cubitals: = post-nodal spaces; q.v.

Post-dorsulum: the middle piece of the meta-notum, between the mesophragma and post-scutellum.

Post-embryonic -otic: the stage after the insect has come out of the egg.

Post-epistoma: that part of the head behind the clypeus in Hymenoptera: see also post-clypeus.

Posterior: hinder or hindmost: opposed to anterior: in Diptera; applied to that face of the legs which is not visible when viewed from the front, the legs being laterally extended.

Posterior angle: of thorax, in Coleoptera, is the lateral angle near base of elytra: of the wings = hind angle; anal angle; q.v.

Posterior cells: in Diptera (Will.): 1st radial 5 (Comst.): 2d = medial 1 (Comst.): 3d = 2d medial 2 (Comst.) 4th = medial 3 (Comst.): 5th cubitus 1 (Comst.).

Posterior cephalic foramen: in Odonata, the opening of head posteriorly through which the cavities of head and thorax communicate.

Posterior field: of tegmina, = anal field; q.v.

Posterior intercalary: in Diptera, is one of the anal veins (Comst.).

Posterior lateral margins: in Orthoptera, extend from base of pronotum downward to the posterior angle of sides.
