These females agree with the description with the exception 

 of the bristles on the tarsi, which are black, not white as 

 stated by Macquart, but the rounded angle of the anterior 

 branch of the fourth vein emitted from the discal cell is 

 present, though not quite so exaggerated as given in the 

 figure; the white hairs below the first two joints of the 

 anlennce are here more reddish and black. Forehead with 

 black bristly hairs. Thorax with white tomentum on the 

 testaceous sides. Prse3utural bristles three in number — one 

 supraalar, two postalar, — all black, and three or four weak 

 dorso-central bristles on each side, pubescence on dorsum 

 black and numerous. Scutellum brown, with grey tomentum 

 and four black bristles on its posterior border. Abdomen 

 with two black bristles on each side of the first segment ; 

 dorsum with short white pubescence, and the usual circle of 

 spines at apex. Femora and tibise with short white pubes- 

 cence also present on the first joint of the tarsi and partly on 

 the other joints ; all the legs with numerous black bristles.

A male and female from Queensland and a female from 

 Sydney have a good many black bristles on the legs, and the 

 four bristles on the scutellum are black, not yellow. Others 

 from Queensland have the pale colour of the legs more yellow 

 than red, and are smaller in size. 



This appears to be a rather variable species, differing" in 

 size and general appearance. 



Neodiogtkia, gen. no v. 



Established for one species from Sydney which has a 

 superficial resemblance to TJioctr'ia celandica, of Europe, but 

 is at once distinguished by the shape of the antennae, which 

 are not situated on a projection, and the first two joints are 

 almost equal in length, in other respects the characteristics 

 of the genus are very similiar to those of Dioctria, the abdo- 

 men is slender. Wings large. Legs slender and nearly 

 bare. Scut' Hum with no bristles, moustache on f:-ice almost 

 confined to the oral margin.
