Type, a male, seen in Paris Museum, 12.4. 11, described 

 by Macquart as from unknown locality : a label below gives 

 " New Holland " ; no doubt this is correct, as the genus, at 

 any rate as yet, is peculiar to Australasia. It is a species 

 of Thereutria distinguished from T. amaracus and T. jndchra 

 by the wholly black legs and brown tvings. A blue-black 

 species. Abdomen with white spots at sides of segments 

 2-6. Face with white lines on each side, flat, hardly raised 

 at oral opening. Moustache white. Antenna gone, except 

 the first two joints, which are black, with black pubescence. 

 Wings brownish, the fourth posterior cell narrowed at border, 

 the anal almost closed.
