ART. 6 NOTES ON ORIENTAL SAPEOMYZID FLIES MALLOCH 63 



black color becoming progressively more extensive apically, and 

 covering most, or all, of disk of some of the apical tergites. Legs 

 similar to those of aberraiu. 



Length, 6.5 to 7 mm. 



Habitat. — Sumatra. I have seen only females of this species. 



HOMONEURA (NEOHOMONEURA) LIMBIFERA (de Meijere) 



Lauxania limMfera de Meijeke, Tijdschr. v. Ent., vol. 67, p. 48, 1924. 



I have seen only the male of this species. Closely similar to 

 oHenlalis, but distinguishable by the wing markings (Fig. 42), and 

 the greater proportion of the black color of tergites of basal portion 

 of abdomen. 



Length, 7.5 mm. 



Habitat. — Sumatra. 



HOMONEURA (NEOHOMONEURA) PAROECA (Kertesz) 



Lauxania paroeca Kertesz, Anu. Nat. Mus. Huugary, vol. 13, p. 531, 191.5. 



This species is readily distinguished from its allies by the markings 

 of the wings. (Fig. 44.) The inner cross vein is not clouded, but 

 there are daik markings over outer cross vein and a preapical elon- 

 gate mark before apices of veins 2 to 4 inclusive, the one on third 

 vein being remote from tip of vein, directly below the one just before 

 the apex of second, and usually fused with it. 



Habitat. — Formosa. 



HOMONEURA (NEOHOMONEURA) NIGRONOTATA (Kertesz) 



Lauxania nigrwiotata Keetesz, Ann. Nat. Mus. Hungary, vol. 13, p. 530. 



This species differs from paroeca in having the spots on apical 

 sections of the third and fourth veins almost, or quite, extending to 

 apices of the veins, the one on third not fused with the pi'eapical 

 one on second vein. (Fig. 45.) There is usually a central black mark 

 on one or more of the apical abdominal tergites. 



Habitat. — Formosa.

The above two Sumatran species were described in the same paper 

 as was the subgenus, and they are not known to occur in the 

 Philippines.
