Fungicolous: living in or on fungi. 



Funicle: the joints between the scape and club in geniculate antennae: a 

 small cord : a slender stalk. 



Funiculate: whip-like: long, slender, composed of many flexible joints. 



Funicule: a small, cord-like structure; especially when sheathed. 



Funiculus: the main tendon of abdomen: in Hymenoptera a slender ligament 

 connecting the propodeum to petiole on its dorsal aspect. 



Furca: a fork: the anal appendage used for leaping in Thysanura: see 

 furcula: the forked ental processes of the sternum. 



Furcal orifice: see sternal orifice. 



Furcate: forked; divided into approximately equal divisions. 



Furcula: a forked process: an osmaterium: in Collembola the spring or sal- 

 tatory appendage borne by the fourth abdominal segment : in Orthoptera 

 a pair of backwardly directed appendages which overlie in a more or less 

 forked position the base of the supra-anal plate. 



Furred: covered with dense hair resembling fur. 



Fuscescent: becoming brown; with a brown shading. 



Fusco-ferruginous: brownish rust red. 



Fusco-piceous: pitch black with a brown tinge or admixture. 



Fusco-rufous: red-brown, approaching liver brown. 



Fusco-testaceous: dull reddish brown [brown ocher]. 



Fuscous -us: dark brown, approaching black; a plain mixture of black and 

 red [crimson lake + black]. 



Fused : run together : applied when two normally separated markings become 

 confluent and have a common outline. 



Fusiform: spindle-shaped: tapering gradually to each end. 



Fusulus: = spinneret ; q. v. 



Galea: the outer lobe of the maxilla, usually two-jointed, often hood-like, 

 subject to great modifications in Hymenoptera and Diptera, and forms the 

 coiled tongue in Lepidoptcra. 



Galeotheca: that part of the pupal case that covers the galea. 



Gall: an abnormal swelling or excrescence on a plant, produced by an insect: 

 = cecidium. 



Gallicolous: dwellers in galls, whether as producers or inquilines. 



Gallivorous: feeding upon galls or gall tissue. 



Gamogenesis: reproduction through fertilization: see agamogenesis. 



Ganglion -ia: a nerve centre composed of a cell mass and fibres: the white 

 disc-like bodies connected by a double cord, lying above the ventral surface 

 within the body and forming the centre of the nervous system. 



Gasterotheca: that part of the pupa case that covers the abdomen. 



Gastric: of or belonging to the belly or to the stomach. 



Gastric caeca: = caecum; q. v. 



Gastro-coeli: a pair of usually transverse lateral pits near the base of the 

 second abdominal tergite in some Hymcnoplera. 



Gastro-ileal folds: occur in some insects at the junction of the chylific ven-
