240 THE DIPTEKA-BRACHYCERA OF TASMANIA, 



single specimen, which occuiTecl settled on vegetation at 

 Mangalore, on September 13, 1914. 



Subfamily Oeydromiinse. 



This subfamily is very nearly allied to the Enijiince, and 

 ia some cases it is difl&cult to draw a line of distinction 

 between them. The Orydromiina-, however, can usually 

 be recognised by the anal cross-vein meeting the anal vein 

 at more or less a right-angle, and not becoming confluent 

 with it. Two genera, both of very wide distribution, are 

 known to occur in Tasmania.

58. M I c R o p H o R u s, Macq. (Fig. 47.) 



Proboscis not longer than the height of head. Antennae 

 with the third joint attenuated beyond a broad base, and 

 terminated by a long arista. Wings with the cubital vein 

 unforked ; discal cell with three issuing veinlets, which 

 are all complete ; anal cross-vein rounded and slightly re- 

 current ; anal vein continued only a short distance beyond 

 the anal cell. 



To thisi genus I ascribe provision ally a Tasmanian 

 species, which seems to come nearer to it than to any 

 other genus, although it is not quite typical. It differs 

 principally in the much longer antennal style, but agrees 

 in the form of the anal cell, and the incomplete anal vein, 

 although the latter extends well beyond the anal cell. 



The genus Micropliorus is placed by Lundbeck in the 

 Ocydroiniince, by Melander in the Empince. Personally, 

 it seems to me to be intermediate between these two sub- 

 families, though I think that its affinities are nearest to 

 the Ocydronnince.

 with two narrow dark brown stripes; abdomen brown; 

 legs entirely light brown; wings hyaline, with veins yel- 

 low-brown.
