Procerebrum: the anterior part of the brain, formed by the ganglion of the first primary segment; also termed ocular lobe, froth part it innervates. Process: a prolongation of the surface, margin, or an appendage: any prominent portion of the body not otherwise definable. Process of labrum: in bees = appendicle: q.v. Procidentia: the narrow projecting tip of 7th dorsal segment in Nematinae. Proclinate: directed forward; applied to hair or bristles. Proctodaeum: the invagination of epiblast that produces the anus and intestine as far forward as and including malpighian tubes. Proculiform or Poculiform: hollow, cylindrical, with a hemispherical base, the sides at top straight goblet-shaped. Procumbent: trailing; prostrate; lying flat. Produced: drawn out; prolonged; extended from. Proeminent: said of the head when it is horizontal and does not form an angle with the thorax. Profile: the outline as seen from the side. Profound, Profundus: deep. Prognathus: having the jaws directed forward. Progoneate: with the genital opening on an anterior body segment. Progonia: the anterior angle of the secondaries. Proleg: any process or appendage that serves the purpose of a leg: specifically the fleshy unjointed abdominal legs of caterpillars and certain saw-fly larvae: = abdominal feet: false legs. Proloma: the anterior margin of the secondaries. Prolonged: extended or lengthened beyond ordinary limits. Promeros: the first abdominal segment in Lepidoptera. Prominent: raised or produced beyond the level or margin: standing out in relief by color or otherwise: conspicuous. Promuscidate: with proboscis or extended mouth structure. Promuscis: an extended mouth structure: has been applied to the long tongue of bees and to the rostrate structure in Hemiptera. Pronotal carina: in Orthoptera, the main or median carina on pronotum. Pronotum: the upper or dorsal surface of the prothorax. Pronucleus: the nucleus of male and female elements, spermatozoa and ova, the union of which forms the nucleus of a fertilized ovum. Pronymph: is that stage in certain inctabolous insects in which the larval tissues are completely broken down, and the imaginal tissues are just beginning to build up. Proparaptera: the paraptera of the prothorax: the terms erroneously applied in this connection. Propedes: = prolegs: q.v. Prophragma: the anterior dividing wall of meso-thorax, which is horny and, at its upper edge, bears the connecting membrane between pro- and mesothorax. Prop-leg: = pro-leg; q.v. Propleura: the lateral portions of prothorax. Propleural bristles: in Diptera, are situated immediately above the front coxa: = prothoracic bristle; q.v. Propneustic: larval forms in which only the most anterior spiracles occur. Propodeon: = propodeum. Propodeum: in Hymenoptera, that part of thorax just above insertion of abdomen, and really the first abdominal segment: see median segment.
