Proclinate: directed forward; applied to hair or bristles. 



Proctodaeum: the invagination of epiblast that produces the anus and intes- 

 tine 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.

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 larva- : 

 = abdominal feet : false legs. 



Proioma: the anterior margin of the secondaries.
