II. The anterior branch of the third vein originating a long 

 distance beyond the small cross-vein, and short and 

 oblique. 



183. Plecia fulvicollis, Fabricius. 



P. fulvicollis, Fab., Syst. Antl. 1805; Wiedemann, Auss. Zwf., 

 I., p. 73, 1828; P. doraalis, Walker, Journ. Proc. Linn. Soc. Lond., 

 I., p. 5, 1857; P. amplipennis, Sk., Proc. Linn. Soc. N.S.W., III., 

 p. 1372, pi. XXXIX., fig. 3, 1888. 



I now believe my P. ampUi^ennis to be the same as P. fulvi- 

 collis, Fab. This species has already been recorded from Sumatra, 

 Java, Ternate, Celebes, Yule Island, and New Guinea. The 

 specimens from which my description was taken were collected in 

 Northern Queensland, while a few others, which seem to exhibit 

 some scarcely important variations, came from New Hebrides and 

 New Guinea. 



186. Plecia dimidiata, Macquart. 



P. dimidiata, Macq., Proc. Linn. Soc. N.S.W., III., p. 1377, 

 pi. XXXIX., fig. 6, $, 1888. 



Additional localities for this species may be recorded : — Benalla, 

 Victoria (Helms), in November; South Australia (J. G. O. Tepper), 

 specimens in Coll. S. Aust. Museum ; Brisbane (Dr. J. Bancroft), 

 Ashgrove, Brisbane, and Hamilton, Upper North Pine, Queensland 

 (C. J. Wild), several specimens in Coll. Queensland Museum,. 



The specimens from Hamilton, Upper North Pine, Q., differ in 

 having the thorax opaque instead of nitidous, and the antennae 

 seem to be 2- + 7 -jointed, but these differences, unsupported by 

 any others, do not appear to me to be of specific significance.
