I have not seen any species corresponding to these characters. 

 Ashmead does not seem to have published any description of the 

 species. 



I have omitted from the list of Australian species two which 

 I am convinced have been described as Australian by mistake, 

 and are almost certainly South American. They both belong to 

 the genus Scotaena Klug, of which Ornepetes Guer., is in my 

 opinion a synonym. 



Scotaena fastuosa Sm. 



Thynnus fastuosus Sm., Descr. n.sp. Hymenoptera, p. 170, n.34, 

 1879(5). 



Very near 1'hynnus decorus Sm., from Brazil, which is 

 probably a synonym of Scotaena trifasciata Klug, from Bahia.
