4. Genus PAL>EOGNORISTE, Meunier 
Palaeognoriste. Meunier, ^ilon. Mycetoph. etc. p. 76 (1904). 
Characters. — This fossil genus resembles Gnoriste in having an elongate proboscis but differs 
in the wing venation wherein it resembles Proholaetis, from which it may be distinguished by the presence 
of palpi. The costa is produced far beyond the tip of the radial sector, the base of the media is wanting; 
the anterior branch of the cubitus is disconnected at the base (PI, 4, Fig. I 7); the proboscis is longer 
than head and thorax. Judging from the wing venation this fly may belong to the Sciarinae. 
Type species : P. sciariformis, Meunier.

5. Genus PROBOL/EUS, Williston 
Probolseus. Williston, Trans. Ent. Soc. Lond. p. 261 (i8g6). 
Characters. — Proboscis more than half of the length of the body, slender, directed downwards 
and forwards, composed of five slender bristles; palpi wanting. Antennae sixteen jointed, compressed, 
the joints closely set together; first two joints only little differentiated from the others. Head composed 
almost wholly of eyes ; face very narrow ; front narrow below ; eyes pubescent. Thorax strongly convex, 
nearly bare, a few short bristles on the sides. Scutellum small, with about six small bristles. Abdomen 
slender, elongate, longer than the wings; male organs composed of a pair of simple fleshy forceps. 
Four anterior legs very slender; hind legs stouter and much eloirgate, the femora thickened, and the 
tibise clubbed. Neuration defective ; the proximal portion of the media and of the anterior branch of
