236 THE DIPTERA-BRACHYCERA OF I'ASMANIA, 



mediastinal vein short and incomplete; cubital vein with 

 a short fork, the lower branch in a line with the stem, 

 and not curved downwards, upper branch short ; discal 

 cell truncate, the three issuing veinlets complete ; anal 

 vein incomplete, hardly extending beyond the anal cell. 



Female lias the posterior tibi<e broader, and first joint 

 of posterior tarsi narrower, than in the male, and the 

 abdomen is produced into a long ovipositor ; otherwise 

 it resembles the male very closely. 



This species is easily dintinguishe 1 Prcm all the other 

 known Tasmarian species of Em pis by its very small size, 

 whilst the very long proboscis will at once distinguish it 

 from similar species of Hilar a. 



E. flahili.s frequents flowering heaths in the bush in the 

 ©a.rly spring time. It is apparently local, but probably 

 common where it occurs. I have only met with it during 

 the month of September. 



56. T E N o N T o M Y I A, Gen. nov. (Fig. 45.) 



Wings with the cubital vein simple, but connected with 

 thei radial vein by a cross-vein ; antennae with a very long 

 aristiform style; proboscis less in length than the height 

 of head, and bearing long hairs ; legs very slender and 

 quite simple.

Head a little narrower than the thorax. Proboscis 

 thick, a little shorter than the height of head, and bearing 

 long hairs. Eyes separated in both sexes. Antennae with 

 the first and second joints extremely sma'l, the third ex- 

 panded, nearly oval in shape, and drawn out at the apex 

 into a narrow point, from which springs a long aristiform 

 style, which is about twice as long as the three antennal 

 joints together. Palpi not distinguishable. Thorax con- 

 siderably arched, dorsum almost bare, but with a few 

 long lateral and posterior bristles; scutellum with mar- 

 ginal bristles. Abdomen with short, lateral bristles ; geni- 

 talia of the male narrow, but lengthened. Legs long, par- 

 ticularly the posterior pair, and very slender, all joints 

 simple, and practically bare of either bristles or pubes- 

 cence. Wings of medium size; mediastinal vein straight,
