254 Professor WilHston on the 



2. Viijlosif^, pp. (PI. VIII., fig, 1, wing.) 



$ . Antennae about as long as the wings ; all the joints single, 

 the petioles a little shorter than the thickened portion. Yellow, 

 the mesonotum somewhat brownish, the abdomen, tibiaj, and tarsi 

 iufuscated. Wings nearly hyaline, black haired. Length H mra. 



3. DipJosis, sp. 

 $ . Very much like the preceding species, but with each alter- 

 nate joint of the antenute double. 



4. ? Diplosis, sp. (PL VII r., fig. 2, wing.) 



Two specimens, with the antennfe incomplete, I refer 

 doubtfully to this genus. The antenniis are not petio- 

 lated, and resemble those of Asphoiidulia, but have the 

 joints provided with long hairs, as in this geous. 



AVlNNEETZIA. 



Rondani, Dipt. Ital. Prodri, 1856. 

 1. Winnertzia, sp. (PI VIII., fig. 3, wing.) 

 Two specimens, male and female ; both injured. 



MlASTOR. 



Meinert, Natur. Tijdschr., 3 P., iii., 150, 1864. 



1. Miastor, sp. (PI. VIII., figs. 4, wing ; and 4a, part of 

 antenna.) 



A single specimen of a species which seems to present 

 all the essential characters of this genus. The wings 

 have the first and third veins distinct, but lack the 

 posterior forked cell. The legs are short and not slender. 

 The tibiae are as long as the first two joints of the tarsi 

 together, and the first joint is a half longer than the 

 second. 



Haplusia. 



Karsch, Revision der Gallmiicken, p. 15, 1878. 



1. Haplusia, sp. (PI. VIII., fig. 5, wing.) 



A single specimen of a minute species shows evident 

 relationship to this genus, though I am not fully satisfied 

 that it should be located in it.
