30 Miss G. Ricardo on the 



Diatomineura violacea, Macquart, Dipt. Exot., Suppl. iv. 

 p. 326, pi. ii. fig. 3 (1849) [Pangonia]. 



Two females from Kuranda, N. Queensland (F. P. Dudd). 

 Presented by F. H. Taylor (1914). In Brit. Mus. Coll. 



Three females from Cairns, N. Queensland, 1907. 



One male (type) from Herberton, iu German Ent. Museum 

 Coll. 



The type was described as from Tasmania. Macquart's 

 description does not altogether suit these specimens, as he 

 makes no mention of the lighter colour of legs, only alluding 

 to the knees as a little testaceous, and his figure of the head 

 shows the palpi as slender, whereas in these they are very 

 broad. However, I have little doubt they are this species. 

 It is just possible that the locality specified may be incorrect, 

 as Mr. A. White writes to me that in his three years' col- 

 lecting in Tasmania he has only come across three species 

 of Pangonia, and this is not one of them. 



A small metallic- blue species with bright reddish-yellow 

 antennae and palpi. 



Length 8 mm. 



$ . Face dark, with some grey tomentum and with black 

 pubescence. Beard blackish (Macquart speaks of it as 

 tawny). Proboscis 2 mm. long. Palpi short, reddish 

 yellow, the second joint broad, ending in an obtuse point, 

 the upper edge curved. Antenna reddish yellow, the first 

 two joints yellowish, with black hairs. Eyes hairy. Fore- 

 head parallel, about five times as long as it is broad, covered 

 with grey tomentum and some short dark hairs ; frontal 

 callus small, oblong, not reaching eyes, with a lineal exten- 

 sion. Ocelli present. Thorax, scutellum, and abdomen blue, 

 metallic, shining, some traces of grey tomentum on the 

 thorax and also on the underside of abdomen. Legs blackish, 

 all the tibise and tarsi a dull yellowish in the specimens 

 from Cairns and Herberton. Wings large, extending far 

 beyond the abdomen, clear ; stigma yellowish ; veins 

 brownish ; first posterior cell open, but slightly narrowed at 

 border. 



$ . Is similar, the black hairs on the face are very long 

 and thick, and also numerous on the first two joints of 

 antenna?. Palpi yellow, with thick black pubescence. Legs 

 blackish, the pulvilli very much larger than in female, with 

 abnormal bright yellow prolongations four or more in 

 number.
