Encased female. — The adult female, which is always encased within its pupal skin. 

 Endoparasite. — A parasite which lives at some time during its biology in the interior 



of its host. 

 Epicranium. — The dorsal part of the head bearing the eyes, ventrally fused with the 



genae with which it limits the buccal cavity. 

 Epimeron. — Used by Audouin for Scutum. 

 Exuvium. — -The pupal skin after the exit of the male. 



F. 

 Female. — See Encased female. 



Femoralia. — Pleural segments on each side of the male postscutellum. 

 Flabellate. — Referring to the antennae with lateral prolongations of the joints. 

 Foreign host. — The host of another parasite and not of the species in question. 

 Free larva. — The Triungulinid or Campodeoid larva. 



G. 



Genx. — The plates at the sides of the eyes beneath, under which the mandibles and 

 maxillae arise. 



Genital apertures. — The unpaired median ventral openings from the female body cav- 

 ity into the brood canal. 



Genital pore. — In the male, the pore at or near the tip of the cedeagus through which 

 the penis may be exserted. 



//. 



Heterophagous. — Applied to larvae which have to be fed by others. 



Hcxapod. — A term incorrectly used to designate the triungulinid; as it is generally

 Bill. — A colony of fossorial insects in which division of labor is practiced, as, for 



instance, ants and termites. 

 Hive. — A social colony of Hymenoptera constructing the nest of wax. 

 Host. — That insect which directly or indirectly furthers the life of the parasite. See

 Host plant. — A plant habituated by a certain species of insect. 

 Hypermetamorphosis. — A complete metamorphosis in which the larva or pupa assumes

 Hypopygium. — A term used by authors in referring to the ninth abdominal segment of

Instar. — Any successive stage in the metamorphosis, limited by two successive molts. 

 Interlumbium.— Used by Saunders for Scutellum. 



L. 



Labium. — The labium is absent, although the embryo discloses the corresponding 



lobe. 

 Labrum. — The labrum is absent; even in the embryo it is not represented by a lobe. 

 Larv.se.— See Campodeoid, Carabidoid, Coarctate, Free, Parasitic, Scarabseidoid, Second, 



Third, Triungulinid. 

 Larviparous reproduction. — The production of living young from the body of the parent. 

 LumM,— The Bide pieces composing the scutum . 



M. 



Mandibles. — The ensiform chitinous appendages arising under the genae. 

 Mandibular analogue. — See Analogue.
