112 OEPHID^l. 



Julii either by having the transverse basal nervure 

 interstitial (in which case the terebra is as long as the 

 body) or by the terebra being shorter than the abdo- 

 men. 



South of Scotland, Hertford, Norfolk (Stephens), 

 Worcester (Fletcher), Glanvilles Wooton (Dale). 



Continental distribution : Sweden, Germany, France. 



Family CEPHID^. 



Antennae thickened towards the apex, rarely filiform, 18- to 30-jointed. 

 Labium three-lobed ; labial palpi 4-, maxillary 6-jointed, long. Tibiae 

 spined. Anterior tibiae with only one spur. Pronotum long, nearly as 

 long as the mesonotum; middle lobe of mesonotum small, broader than 

 long, not reaching the scutellum. Cenchri hidden. Abdomen com- 

 pressed ; ovipositor projecting, nearly one-half longer than the last 

 segment. Wings with the first cubital cellule short. 



The larvae are footless, except six tubercle-like 

 thoracic legs, white and fleshy and provided at the 

 anus with a projecting point, which may be capable of 

 being retracted telescopically. They are white, have 

 horny, strongly built heads, and very powerful jaws. 

 According to Riley (Insect Life, i, p. 10) they have 

 placed rather near to the small eyes (at least Cephns 

 (Phylloecus) integer, Norton) extremely small six- to 

 seven-jointed antennae, the basal three joints being the 

 stoutest ; the antennae in C. pygm&us are stated by 

 Curtis to be four- jointed. They are internal feeders, 

 feeding usually on the pith of the plant. Cephus com- 

 pressus, Fab., lives in the buds of the pear ; C. abdo- 

 minalis feeds on the flowering buds of fruit trees, or, 

 according to Audouin (cf. Westwood, Int., ii, p. 112) 

 in the young slender shoots of the pear ; C. phtisicus 

 in the branches of the rose ; C. xanthostoma, Evers- 

 mann, in the stem of Spircea ulmaria ; G. linearis in 

 the common reed ; another species is described by 

 Ferris as feeding in the bramble ; G. femoralis in 

 the stems of willows and oak ; and G. pygm&us in 

 corn ; and in America G. integer, Norton, in willow
