e type of the
genus in which the describer of the genus placed it, subsequent to
the description.

Genosyntype: one of a series of species upon which a genus is
founded, no one species being mentioned as type.

Genus: knee; the joint between femur and tibia.

Genus: an assemblage of species agreeing in some one character or
series of characters; usually considered as arbitrary and opinionative,
though some consider it a natural assemblage.

Geometrid: larva which, when walking, alternately elevate and
straighten the middle of their body: opposed to rectigrade; q.v.

Geodephagous: = adephagous; q.v.

Geodromica: terrestrial Heteroptera in which the antennae are not
concealed.

Geophilous: living on the ground: species that live on the surface or
come freely into contact with it.

Germanium: an ovary: that portion of an ovarian tube containing the
cell elements.

Germ-ball: reproductive cells in larvae from which, exceptionally,
young may develop as buds.

Germ-band or Germinal band: that portion of a young embryo which
is to become the future insect, when it is in the form of a band or
strap and may or may not show the division into the future segments.

Gerontogeic: belonging to the old world: see neogeic.

Gibba: a rounded protuberance or prominence.

Gibbous: hump-backed; protuberant: said of a macula when it
resembles a moon more than half full.

Gibbus: when the whole surface forms a hump or obtuse cone.

Gills: respiratory structures which function in water; distinguished as
true or blood gills where contained blood conveys the absorbed oxygen
from the gill to the tissues, and as tracheal gills when this conveyance
is by contained tracheae.

Gilvus: = flavus; q.v.

Ginglymus: a hinge joint that permits flexion in one plane.

Gizzard: a pouch-like structure between the crop and chylific ventricle
furnished with chitinous teeth or plates, in which the food is prepared
for the digestive juices by grinding or merely sifting = cardia.

Glaber-rous: smooth; free from all vestiture.

Gland: a cellular sac which separates or secretes from the blood
specific portions to produce characteristic products - e.g. wax,
saliva, silk, etc.

Gland-bearing prominence: in Diaspinae a prominence on the margin,
bear-ing a gland opening on the dorsal surface.

Gland orifice: in Coccidae, the external opening through which a gland
pours its secretions.

Gland spines: in Coccidae; spiny appendages, each of wh
