duced into a triangle which descends to the base of the antennae ; 

 ocelH small, laterals contiguous to the eye margin, the middle 

 one minute, placed in a groove at the base of the frontal tri- 

 angle. Legs strong, with tibial setae which on the hind legs 

 are noticeably longer than the diameter of the tibia at the 

 widest part. Costa more or less produced beyond the tip of 

 Rs ; fork of the cubitus under or proximad of the fork of the 

 media, the angle at the base very acute, the branches slightly 

 diverging, anal strong but incomplete. 



Tabic of Species. 



a. Wings unspotted, hyaline. 



b. Cubitus forks proximad of the prominal end of the crossvein 



by the length of this vein. 



c. Humeri dusky yellow ; costa produced. i. pulicaria. 



cc. Humeri black ; middle ocellus absent ; costa produced but 



little if at all. MycctopMla anomala n. sp. 



bb. Cubitus forks under the crossvein. ]\Iycetophila vitrea. 



aa. Wing marked with brown. 



b. Mesonotum shining, unicolored, blackish; a single spot on the 

 wing. 2. pitnctum. 



bb. ^Mesonotum yellowish with 3 dark subconfluent stripes, or some-

After examining the type at Cambridge, I may add that the 

 humeri are dusky yellow, Ri and Rs curved parallel to the costa. 

 the cell between quite narrow, cubitus forks the length of the 

 crossvein proximad of the proximal end of the latter.
