8. GENUs MEGHYPERELLA, MEUNIER 
Meghyperella, Meunier, Ann. Sc. Nat. (Zool.) 9 ser. Vol. 7. p. 112 (1908). 
Characters. — Antennz three-jointed, the last joint conical, a little longer than its distinct 
arista. Wings rather broad and pointed, the discal cell emitting two posterior veins, the intercalary 
absent. The genus is apparently related to Leftofesa, differing in the possession of a more generalized 
arista. It may bea predecessor of Stenofroctus.

9. GENUS MESOMYITES, COCKERELL 
Mesomyites, Cockerell, Proc. U. S. Nat. Mus. Vol. 52, p. 377 (1917). 
Characters. — Mesomyites was originally described as a new genus of the Empididz, and the 
small size, slender wing and general features of the neuration are suggestive of the Clinoceratinz. 
However, the second basal cell emits a vein parallel with the discal cell, the second branch of the cubitus. 
Thus the anal cell is widely open, an impossible condition among the Brachycera. Dr. Cockerell, 
in Nature, Vol. 103, p. 44 (1919), has referred his genus to the anomalous tipulid genus Síyriugomyia. 
The species on which Mesomyites was based is the following.
