4. GENUS EMPIDIA, WEYENBERGH 
Empidia, Weyenbergh, Arch. Mus. Teyl, Haarlem, Vol. 2, p. 258 (1869). 
Characters. — Handlirsch, who has examined the type, states that it is not all at clear that 
this fossil belongs to the Empidida. The length of the specimen is about nineteen millimeters. — The 
Empis wing pictured with the fossil has nothing to do with the insect.

5b. GENUS EUTHYNEURELLA, MEUNIER 
Euthyneurella, Meunier, Ann. Sc. Nat. (Zool.) 9 ser. Vol. 7, p. 113 (1908). 
Characters. — « This genus differs from Eufhyneura Macquart by some small peculiarities in 
the wings and by the scutellar hairs not being vertical. » From the figures of the wing and of the 
antenna the insect seems to be a Tzchina.

6. GENUS HASMONA, GIEBEL 
Hasmona, Giebel. Ins. Vorwelt, p. 209 (1856). 
Characters. — This species is apparently Nematocerous, according to Handlirsch. The 
distinctive feature of the genus is the neuration which Giebel states is unlike that of living Empids. 
There is a strong simple vein extending parallel to the costa to the wing-tip, followed by three simple 
veins united before the middle by an oblique crossvein. The insect measures two millimeters.

7. GENUS HILARITES, HEER 
Hilarites, Heer, Viertjahresb. Naturf. Ges. Zürich, Vol. 1, p. 38 (1856). 
Characters. — Heer stated that this insect apparently belongs to Hilara, but since the wings 
are not preserved it was impossible to make a certain determination.
