  • noun In ornithology, one of the uncinate processes borne upon most of the ribs of a bird, forming a series of splint-bones passing obliquely backward from one rib to overlie the succeeding rib or ribs, and thus increasing the stability of the walls of the thorax.
  • noun In entomology, the outer side of a beetle's wing-cover when it is inflexed or turned down so as to cover partially the side of the thorax and abdomen. Also called the side-cover.

  • Epipleural: the deflexed or inflexed portions of the elytra, immediately beneath the edge: the inflexed portions of the pronotum are sometimes called prothoracic epipleura: as generally used, the term is incorrectly applied to the entire bent under margin of the elytra.

    Explanation of Terms Used in Entomology

  • Germar is of opinion that this is the same as natator, F.; but on comparison, I find it to ditfer in many small characters, the most obvious one of which is the colour of the epipleura, that of the natator being light piceous, whilst in the analis it is of a bronzed black, &c.
