84 AN ACCOUNT OF BRITISH FLIES. 



included in the British Fauna. The only true British species is 

 E. longipes. PI. i. (3). 



E. longipes, Lw.* 



Low describes the ?, and Walker g'ves a good figure. Mr. 

 Haliday took it in Tullamore Park, Ireland. The antennee are about 

 twice the length of body, and i6-jointed in the <?. Wings large, 

 much longer than body. Legs long and slender. PI. i. (3). 



E. defecta, Lw. 



This is a reputed British species. The larv?e live in decaying 

 beechwood. 



The imago is pale yellow, the extremities of pincers black. 

 Antennae pale brown, 15-jointed, with whorls of very long hairs. 

 The last joints of tarsi white. Wings long and narrow, with pale 

 gray hairs and pale brown veins ; slightly iridescent. Antennre of 

 ? 13-jointed. Ovipositor long, no lamellae. Colours fade at 

 death. 



Sub-Genus. — Asynapta, Lw. 



Of the sub-genus Asynapta, Taschenberg remarks that it may be 

 divided into two groups. PI. i. (4). 



First group {Asynapta, Rondani), lengthened neck and large palpi, 



with four very long joints. 

 Second group ( Winnertzia, Rond.), unlengthened scutum, smaller 



palpi, with four only moderately-lengthened joints. 



Asynapta lugiclris, Lw.f 



The larvae of this gnat live in decaying beechwood, according to 

 Schiner. Taschenberg describes the ? as piercing the budding 

 leaves of the plum to lay her eggs therein, and the larvae as inhabiting 

 lemon-shaped galls in June. They pupate in August. 



Imago. — Scutum black-brown and shiny ; sides dark yellow ; 

 abdomen yellow with whitish-gray hairs. Palpi very hairy. Antennae 

 1 4-jointed, joints double the length of petioles. Legs yellow. Wings 

 blackish with dark hairs ; first longitudinal vein apparently distant 

 from front edge ; second longitudinal vein rising steeply, finishing in 

 the tip of the wing. Antennas in ? short ; ovipositor long, two long 

 lamellae. Parasites attacking this species : Pteromalus piscipalpis 

 and Eufytoma AmcrHiigi.
