Explanation of Terms Used in Entomology Part 69

Pubis: the lateral region of the prothorax.

Pulmonarium: the membranous connection of the plates or scutes of the abdominal rings: = connexivum.

Pulsatile: having the power of pulsating or moving in a rhythmic manner: applied to special organs in the legs, which aid in circulating the blood in these appendages.

Pulverulent: powdery or dusty in appearance.

Pulvilliform: having the appearance or structure of a pulvillus.

Pulvillus -i: soft, pad-like structures between tarsal claws: the cus.h.i.+ons of short, stiff hair or other clothing on the underside of tarsal joints; rarely fleshy lobes: see arolium.

Pulvinatus: moderately convex.

Punctate: set with impressed points or punctures.

Punctiformis: shaped like a point or dot.

Punctulatus: with small punctures.

Puncture: an impression like that made by a needle.

Punctured: marked with small, impressed dots.

Puniceus: carmine red [carmine].

Pupa: the intermediate stage between larva and adult; loosely applied for all orders, properly only for those with a complete metamorphosis: a pupa is obtect, when inclosed in a rigid case on which the members may or may not be outlined. It is liber, or free when the appendages are separately encased and there is no covering over the whole: see chrysalis.

Puparium -ia: in Diptera, the thickened larval skin within which the pupa is formed.

Pupate, Pupation: to become a pupa: the act of becoming a pupa.

Pupiferous: applied to that generation of plant lice which produces s.e.xed individuals.

Pupigenous: =pupiparous; q.v.

Pupigerous: forming a larval pupariuni: coarctate: said of dipterous larva that contract to form an envelope for the inclosed pupa.

Pupil: the central mark of an ocellate spot.

Pupillate: spots or marks that have an eye-like centre.

Pupipara: a series of Diptera, in which the females do not extrude the young until they have reached the stage ready to pupate.

Pupiparous: bringing forth young ready to pupate.

Pupivorous: feeding upon pupa: especially applied to those Hymenoptera that are parasitic upon insects in the pupal stage.

Purpurascent: becoming purple in shade.

Purpureous -eus: purple [mauve].

Pustular a colored point of moderate circ.u.mference.

Pustulated hair: in Mallophaga those arising from unchitinized s.p.a.ces.

Pygidium: the last dorsal segment of abdomen left exposed by the elytra: in Forficulidw, the last dorsal segment: in Diaspincr, the compound terminal segment.

Pygofer: the last segment of the abdomen in certain h.o.m.optera, especially the lateral margins which appear in the ventral view; hence sometimes used in the plural - pygofers.

Pygoph.o.r.e: the large upper piece of the genitalia in h.o.m.optera.

Pygotheca: the parts containing the genitalia in h.o.m.optera.

Pyloric: referring to the posterior extremity of the chylific ventricle.

Pyloric valve: the specialized posterior portion of crop where there is no distinct gizzard.

Pyloric valvule: a circular projection of the stomach behind which is an enlargement of the intestine.

Pylorus: the chylific ventricle.

Pyriform: shaped like a pear.

Q

Quadra -ri -ro: as a prefix, means four.

Quadrate: square or nearly so.

Quadrifarium: having four rows.

Quadrilateral: four-sided: formed or bounded by four lines: in Odonata, a s.p.a.ce on the wings of Zygoptera bounded by the lower sector of arculus, the sub-median vein, a cross-vein between these two, and the lower part of arculus.

Queen: the actively reproducing female among worker insects.

Quiescent: not active: applied to the pupae in forms with complete metamorphosis.

Quiet: subdued: not conspicuous or contrasting in color or maculation.

R

Race: a variety of a species possessing constant characters which yet are not specific; usually occurring in a different faunal region from the type and may thus be geographical: nearly synonymous with subspecies.
