Ptilinum: in Diptcra cyclorrhapha. an inflatable organ capable of bcin^ 

 thrust out through a frontal suture just above the root of antenna. 



Ptilota: winged insects. 



Pubes or Pubescence: short, fine, soft, erect hair or down. 



Pubescent: downy: clothed with soft, short, fine, closely set hair. 



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 cushions 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 en- 

 cased and there is no covering over the whole : see chrysalis. 



Puparium-ia: in Diptcra. 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 sexed 

 individuals. 



Pupigenous: = pupiparous ; q. v. 



Pupigerous: forming a larval puparium : coarctate : said of dipterous larvae 

 that contract to form an envelope for the inclosed pupa. 



Pupil: the central mark of an pcellate spot. 



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



Pupipara: a series of Diptcra. 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 pupae: especially applied to those Hymenoptera 

 that are parasitic upon insects in the pupal stage. 



Purpurascent: becoming purple in shade.
