Fic. 20.—Wing of Bradysia. 
_ Walker describes this from a specimen in the British Museum. 
It seems to agree closely with Angustipennis, described in detail ( ¢ ) 
by Winnertz, and this author says concerning this point: ‘‘ Die 
Identitat derselben mit Sciara brevipennis, Walk, ist nicht unwahr- 
scheinlich.” Dale has taken this under stones in company with ants. 
Genus.--Zpidapus, Hal = Chionea, Curtis. 
Thorax much compressed behind, so as to seem conical from 
above. Wings and halteres wholly obsolete. Abdomen incrassate in 
the middle ; tip attenuated, decurved, furnished with the ordinary two 
linear obtuse pubescent and free valves of the ovipositor. 
Fic. 21.—Epidapus venaticus. 
£. venaticus, Hal. 
Thorax black ; abdomen piceous, hairy; palpi yellow; antenne 
shorter than body ; legs testaceous ; lamellz of ovipositor round. 
The larve live in the rotten wood of Carpinus betulus. 
GENUS.—Zygoneura, Mg. 
Osten-Sacken places the genus in the Cecidomyidz on account of 
the following characters; (1) the coxz being far less elongated, and 
the spurs of the tibize far shorter than in other genera of the AZyceto- 
philide ; (2) antenne moniliform with verticillate hairs, seen in 
Cecids, but never in ‘‘ Fungus Gnats.” The same author continues
