Pavillions: the sheds or cells sometimes built by ants as a shelter for groups of plant lice. Paxilla: a small stake or peg: a bundle of spicular processes. Pearlaceous: having the appearance of pearl. Pecten: a comb: in Hymenoptera, rigid, incurred setae on the basal parts of maxilla and labium: the rows of spines on the feet of pollen-gathering bees: any series of bristles arranged like a comb: in mosquito larvae the comb-like teeth on the breathing tube. Pectinate: comb-shaped: with even branches like the teeth of a comb. Pectinato-fimbriate: having pectinations that are fringed with hair. Pectoralis: relating to the breast. Pectoral plate: in Coleoptera, the sternum. Pectunculate: with a row of minute appendages like the teeth of a comb: e.g. some maxillary structures. Pectus: the ventral portion of thorax: variably applied in Coleoptera, for the entire meso- and meta-thorax: also the pro- and meso-sternum: in Diptera, is the inferior surface of the thorax between the legs. Pedal line: in caterpillars: extends along the base of the feet. Pedal tubercle: on the thoracic and abdominal rings of caterpillars: on the anterior side of leg-base and, correspondingly, on apodal segments: is VII of the abdomen where it consists of three setae: VI of the thorax where the setae are not numbered: constant (Dyar). Pedamina: the aborted fore-legs of Nymphalid butterflies. Pedate: foot-bearing, or having feet. Peddler: applied to the larvae of such Cassid beetles as carry their excrement and cast skins on an anal fork. Pedes: the feet, or really, legs. Pedicellus or Pedicle: the third joint in a geniculate antenna: forming the pivot between scape and funicle: in general, a stalk or stem. Pediculosis: a state of lousiness, or the abnormal condition caused by the multiplication of lice on the body: sec phthiriasis. Pediculous: lousy: infested with lice. Pedigerous: feet bearing. Peduncle: a stalk or petiole: the basal joint of the antenna in Homoptera: the smaller of the two stalks supporting the mushroom body; q.v. Pedunculated: set on a stalk or peduncle: attached by a slender stalk or neck. Pelagic: inhabiting the sea, far from land. Pellicles: the exuviae or cast larval skins of many insects: in Coccidae more especially applied to the hardened larval skin attached to the puparia of Diaspinae. Pellit: covered with long, drooping hairs, irregularly placed. Pellucid: colored, but transparent: sometimes applied when there is no color. Pelotons: the balls of fine tracheae in larvae, developed to supply the adult organism. Pelottae: =arolia: q.v. Peltate: shield- or target-shaped. Penal claspers: in Proctytripidae. lateral fringed processes of the male genitalia. Penal sheath: the horny outer covering of the penis. Pencil: a little, elongated brush of hair: in Diptera, applied to a group of sensory hairs on the flagellum of the antenna. Pendent: hanging down. Pendulous: drooping: hanging free, attached to one end only.
