Walker describes this from a specimen in the British Museum. 

 It seems to agree closely with A^igustipennis, described in detail ( ? ) 

 by Winnertz, and this author says concerning this point : •' Die 

 Identitat derselben mit Sciara brevipetmis, Walk, ist nicht unwahr- 

 scheinlich." Dale has taken this under stones in company with ants. 



Genus. — Epidapus, }ia.\= C/u'ouea, 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. 



Fig. 21. — Epidapus venaticus. 



E. venaticus, Hal. 



Thorax black ; abdomen piceous, hairy ; palpi yellow ; antennae 

 shorter than body ; legs testaceous ; lamellae of ovipositor round. 

 The larvae live in the rotten wood of Carpinus betidus. 



Genus. — Zygoneura, Mg. 



Osten-Sacken places the genus in the Cecidomyidae on account of 

 the following characters : (i) the coxs being far less elongated, and 

 the spurs of the tibiae far shorter than in other genera of the Myceto- 

 philidce ; (2) antennae moniliform with verticillate hairs, seen in 

 Cecids, but never in " Fungus Gnats." The same author continues
