104 Miss G. Ricardo — A Revision 



From east coast of New Holland. Museum. Macquart, 

 Dipt. Exot. Suppl. iv. p. 332. 



Through the kindness of M. Surcouf I was able to see the 

 male and female types of this species in the Paris Museum in 

 the spring of 1908, and was confirmed in my opinion that 

 Macquart in describing the genus was in error in stating that 

 the hind tibia? are unprovided with spines, which are quite 

 distinct in these types, and his drawing of the wing is in- 

 correct, the anal cell being open, though narrowed, at border, 

 and the anal vein is curved. This establishes the synonymy 

 of the genus Ccenopnyga formed by Thomson with Macquart's 

 genus. See my remarks in the ' Annals ' (7) vol. v. p. 101 

 (1900). 



I also discovered that P. personatus, Walker, is identical 

 with this species and that the specimens I identified as 

 P. macvlipennis are a new species. From Schiner's descrip- 

 tion of P. oniatus, there is no doubt it is identical with 

 Macquart's species, Schiner being unable to identify it from 

 Macquart's description, though he remarks it is very nearly 

 related. The species is recorded by Macquart from Australia, 

 by Schiner from Auckland, New Zealand, and by Williston 

 from Queensland. 



There are specimens in the Brit. Mus. Coll. from Australia 

 {Hunter); the Walker type (a female) and males from New 

 South Wales between Sidney and Moreton Bay {Stuchbury) . 

 In Mr. French's collection sent to me for identification there 

 are males and females from Victoria. The palpi in Macquart's 

 types are small with white hairs, the proboscis hatchet-like, 

 the face convex with small pits on each side. Forehead 

 broad and short with ocelli, pubescence black. Antennas red, 

 awl-shaped. Eyes bare. Abdomen reddish brown, with three 

 grey tomentose bands on the second, third, and fourth seg- 

 ments, produced in the middle as a roundish spot, the 

 segmentations red-haired. Thorax in male and female 

 blackish, with three indistinct grey stripes. Legs wholly red. 

 Wings hyaline, with a black- brown fore border and three pale 

 brown-coloured bands of spots — the first at the base of basal 

 cells ; the second extending from the fore border of wing over 

 the middle cross-veins to the fifth longitudinal vein; the third 

 is divided into spots, so that the anterior one is situated in the 

 middle of the second longitudinal vein, with the second spot 

 almost joining it, lying round the base of the fork of the 

 third vein, and a third quite isolated spot is present at the 

 apex of cliscal cell; besides these spots, the apex of second 

 longitudinal vein and upper branch of third longitudinal vein
