Part 116

Pre-basilar: before the base.

Precocious stages: generally applied to all stages of development from the fertilized egg to the pupa.

Precurrent: continuous: entire: complete: said of a vein.

Predaceous: applied to insects that live by preying upon other organisms.

Predatory: = predaceous: q.v.

Pre-eruciform: before the caterpillar stage: specifically applied to the early larvae of some Proctytrypidae.

Preformation: the doctrine of growth or development from already existing rudiments; opposed to epigenesis: q.v.

Pre-furca: "the stem vein in front of a fork, that reaches back to where itself forks from another vein"; Diptera.

Pregenicular: in Orthoptera, that portion of femur proximad the knee.

Pregenicular annulus: a more or less conspicuous color ring on the caudal femora proximad the knee in Orthoptera.

Pre-halter: a membranous scale in front of the true haltere of a fly.

Prehension: structures fitted for grasping or holding.

Pre-mandibular: situated in front of the mandible: applied to a temporary segment of the embryo: = intercalary segment.

Pre-media: Ephemeridae; an apparently distinct vein between radius and media (Comst.).

Premorse: as if bitten off: with a blunt or jagged termination.

Prensor: the genital lateral clasping organ of male Lepidoptera: see clasper.

Pre-ocular: see prae-ocular.

Pre-oral: in front of the mouth: the embryonic head segments before those bearing the mouth parts.

Prepuce: =praeputium; q.v.

Pre-pupal: that stage in the larva just preceding the change to pupa.

Pre-scutellar bristles: in Diptera, are in a transverse row in front of the scutellum.

Pre-scutellar callus: = post-alar callus: q.v.

Pre-scutellar rows: in Diptera, short rows of small bristles in front of the scutellum.

Press: =filator; q.v.

Pressure plate: a structure at base of pulvillus, which exerts a pressure on the sole of the pad.

Pre-sutural bristles: in Diptera, in a trigonate depression at outer ends of transverse suture, near dorso-pleural suture.

Pre-sutural inter-alar bristle: the single bristle of the interalar series, situated before the transverse suture.

Primaries: the anterior or fore-wings.
