 tibiae black at apex ; anterior tibiae Avith no spines ; tarsi 

 black. Wings clear, a little yellowish ; apex slightly 

 brownish. 



From New South "Wales. Coll. M. Fairmaire and M. Bigot. 

 One specimen in the coll. of Marquis Spinola comes from 

 Sydney Island, Oceania. 



Macquart further remarks, in the second Supplement, that 

 the species which appears common in Tasmania aflbrds him 

 several subtbrms. One female differs from the type by the 

 entire black abdomen, ovipositor, and femora ; another has 

 the femora entirely testaceous ; in the males the abdomen is 

 black and the genital organs blackish testaceous. 



These remarks are fully borne out by an examination of 

 Walker's type and others in the Brit. Mus. Coll. D. digentia 

 has the abdomen entirely black. In some specimens the 

 testaceous colouring, if present, is confined to the last seg- 

 ment. The bristles on the legs are often fulvous instead of
