ABT. 6 NOTES ON OMENTAL SAPROMYZID FLIES MALLOCH 57 



HOMONEURA (CHAETOHOMONEURA) SEMIBRUNNEA (de Meijere) 



Lauxania semibrunned de Meijebe, Tijdschr. v. Ent., vol. 58, p. 91, 1915. 



This species is very similar to the preceding one, the only char- 

 acters for their separation consisting of the color of the thorax, which 

 may be variable, and the structure of the male hypopygium (fig. 31). 



I have seen only a Sumatran specimen sent to me by Doctor de 

 Meijere. 



HOMONEUKA (CHAETOHOMONEURA) GEDEHI (de Meijere) 



Lauxania gedehi de Meijere, Tijdschr. v. Ent., vol. 57, p. 231, 1914. 



The specimen of this species sent to me by Doctor de Meijere is 

 greasy, but the color is evidently normally darker than in obscuripes 

 de Meijere. I have drawn the male hypopygium as it is evident on 

 the specimen without dissection (fig. 34) ; the very long lateral exten- 

 sion of the basal portion should be a good character for the recogni- 

 tion of the species. 



Habitat. — Java. 



HOMONEURA (CHAETOHOMONEURA) OBSCURICEPS (de Meijere) 



Lauxania ol)scuriceps de Meijere, Tijdschr. v. Ent., vol. 67, p. 50, 1924. 



The type specimen before me is a female. I note that there is a 

 faint brown suffusion on the outer cross vein and the apices of veins 2 

 to 4, inclusive, most distinct on second vein, but the grassy condition 

 of the wings in gedehi prevents me from distinguishing if this cloud- 

 ing is present in it also. 



Locality. — Sumatra.

HOMONEURA (CHAETOHOMONEURA) FUMIBASIS Malloch 



Homoneura (Chaetohomoneura) fumiltasis Malloch, Suppl. Ent., vol. 15, p 

 107, 1927. 



The above four species were described in the paper in which the 

 subgenus was described, as above noted. All are from Sumatra. 

 The hypopygium of fv/mibasis is shown in Figure 33, of kocki in 

 Figure 35, of nigrofulva in Figure 36.
