DIPTERA 
60. Genus Mycothera, Winnertz. 
I. Genus SYNAPHA, Meigen 
Synapha. Meigen, Syst. Beschr. Vol. i, p. 227, pi. 26 (1S18). 
Characters. — AntennjE projecting forward, cylindrical, 2 -f- 14 jointed ; eyes round; ocelli three 
in number, placed on the front, the middle one smaller, slightly posterior in position. Abomen seven 
jointed; forceps two jointed, the first joint large, ovate, compressed, hair}', the second joint small, 
knobbed. Tibiae spurred, delicately haired outwardly but without setse. Wing hyaline, the media forked 
a short distance beyond the R-M crossvein, the branches again meeting and coalescing thus forming an 
oval cell on the disc of the wing (PI. 4, Fig. I 4). 
This genus was supposed by Schiner to have been founded upon an abnormal specimen. It has 
not since been recognized. 
Type species : S. fasciata, Meigen. 
Geographical distribution of species : 
I. 5. fasciata, Meigen, Syst. Beschr. \^ol. i, p. 227, pi. 8, f. 7 (1818). Germany. 
Palseosynapha. Meunier, Bull. Soc. Ent. Fr. p. in (1900). 
Characters. — The only difference given by the author of the genus between this and the fore- 
going is in the wing venation. Here the oval cell is much closer to the posterior margin of the wing, the 
media is more curved, and the cubitus forks near or at the base of the wing (PI. 4, Fig. I 5). Found 
in the lower oligocene of the Baltic. No species have been described. 
Gnoriste. Meigen, Syst. Beschr. Vol. i, p. 248, pi. 29 (1818). 
Characters. — Head small, rounded, almost hemispherical, placed low upon the thorax; pro- 
boscis prolonged beak-like (PI. I, Fig. 8); eyes elongated, somewhat bulging, slightly emarginate at 
the base of the antennae; ocelli three, the middle one smaller, placed in a flattened triangle upon the 
broad front; palpi situated near the tip of the proboscis, four jointed, the first joint very small, the 
second largest, the third and fourth oval ; antennae 2 -j- 14 jointed, acuate, projecting forward, the joints 
of the scapus bare, the flagellar joints compressed, cylindrical, pubescent. Thorax ovate, highly arched; 
scutellum small, semicircular in outline; metanotum steep, somewhat arched. Abdomen long and 
slender, compressed, seven jointed, in the male with an almost clavate extremity and small forceps. 
Legs long and slender, all tibiae with lateral setae and with spurs. Wing large, oval, microscopic setulose. 
Costa produced beyond the tip of R4-1-5 but not reaching the tip of the wing; subcostal vein long and
