22 Miss G. Ricardo on the 



Pangoninje. 



The genus Pangonia in sensu striclo is only represented 

 in Australia by two or three species, all doubtful. 



The other three subgenera are fairly well represented, 

 Corkoneura having the smallest number of species. The 

 material in the Brit. Mus. Coll. does not increase very 

 largely, which is a disadvantage, as many of Walker's types 

 are old and worn. 



For a list of the Australian species of Pangoninre, see 

 Ricardo, Ann. & Mag. Nat. Hist. (7) v. p. 112 (1900). To 

 Erephopsis species therein named, E. macidipennis, Macq., 

 E. novaguinensis, Ricardo, and E. bancrofti, Austen, must be 

 added. 



To Diatomineura species add D. ruficornis, Macq., D. hirti- 

 ceps, Nowicki, D. ricardoi, Hutton, and D. dives, Macq. 

 (Corizoneura). • 



From Corizoneura species delete C. angusta, Macq., 

 C. trichocera and C. rubiginosa, Bigot, belonging to other 

 genera. C. alternans and C. sulcifrons, Macq., are probably 

 South African species, see Austen, ' Blood-sucking Flies/ 

 p. 53 (1909), which with synonyms reduces the old species 

 of Corizoneura from Australia to seven.

(1892). 

 Diatomeneura carnea, Bigot, 1. c. 



The type came from West Australia, Bigot's two types 

 from Australia. The identity of the latter types is self- 

 evident at a glance — it is difficult to understand how the 

 author made the mistake ! 



It is a small species, at once distinguished by the unusual 

 sbape of the second joint of the palpi, which is shorter than 

 the first one, short and broad, spoon-shaped, reddish in 

 colour ; the first joint yellower, with long whitish hairs 

 below, the second joint with short black pubescence. Face 

 is very protuberant, reddish with black hairs. Beard yellow. 

 Antennce reddish. Forehead & third wider anteriorly, reddish 

 covered with ashy-grey tomentum. Ocelli present. Eyes
