84 AN ACCOUNT OF BRITISH FLIES. 
included in the British Fauna. The only true British species is 
E. longipes. PI. 1. (3). 
E. longipes, Lw.* 
~ Léw describes the 2, and Walker gives a good figure. Mr. 
Haliday took it in Tullamore Park, Ireland. The antennz are about 
twice the length of body, and 16-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 larve live in decaying 
beechwood. 
The imago is pale yellow, the extremities of pincers black. 
Antenne 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. Antenne of 
2 13-jointed. Ovipositor long, no lamellz. Colours fade at 
death. 
Sus-GEnus.—Asynapia, 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 ( Winnertzta, Rond.), unlengthened scutum, smaller 
palpi, with four only moderately-lengthened joints. 
Asynapta luguiris, Lw.7 
The larve of this gnat live in decaying beechwood, according to 
Schiner. Taschenberg describes the 2 as piercing the budding 
leaves of the plum to lay her egys therein, and the larvz 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. Antennz 
14-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. Antennz in @ short ; ovipositor long, two long 
lamella. Parasites attacking this species: Pteromalus piscipalpis 
and Eurytoma Amerlingt.
