pubescence ; there is only one pair of prescutellar bristles ; 

 scutellum light brown, with small dark brown dots, and 

 bearing two terminal black bristles. Abdomen shining 

 dark brown, with the sides and genitalia brownish-yellow ; 

 sides with white pubescence, genitalia with longer black 

 hairs. Legs light brown, with apex of tibiae and tips of 

 tarsal joints dark brown ; tibiae with black bristles. Wings 

 short and narrow, tinged with brown, and with indistinct 

 spots, the position of which is more easily made out in 

 the female, and will be referred to under that sex ; discal 

 cell much narrowed towards the base; fourth posterior cell 

 open, but narrowed towards the margin ; anal cell closed 

 at some distance above the margin. 



Female differs considerably in appearance from the 

 male; the eyes are very widely separated, and the abdo- 

 men long, narrow, and pointed ; front light brown, exten- 

 sively mottled with dark brown dots ; colouring of thorax 

 and abdomen as in the male, but the abdominal segmenta- 

 tions are light brown, and more distinctly marked ; wings 

 brown, with diffused dark brown spots, the largest cover- 

 ing the apex of the discal cell, a second the apex of the 

 second basal cell, and a third the apex of the anal cell, 

 with a small detached spot within the cell itself ; the first 

 basal cell is mostly occupied by a brown smudge, and 

 there is also an indistinct clouding towards the tip of the 

 wing, crossing the cubital fork. 



This species may be easily distinguished from the other 

 members of the genus by its brown colouring, small mot- 

 tled wings, and eyes Avith cross-furrows. It is not a typical 

 Pitilorephala, and when more Australian species are avail- 

 able for comparison, it may be necessary to place it in 

 a distinct genus. In the character of the furrowed eyes 

 it agrees with von Krober' s genus Acatopygia, but it dif- 

 fers from that genus in its other characteristics. 



P. saxatilis is probably a, mountain species. Only two 

 specimens are known, which were taken by myself on the 

 highest pari of the hills that bound the Bagdad Valley 

 on its eastern side. The female, which was settled on 

 a stone, occurred on January 26, 1912 ; the male was swept 

 from grass on January 1, 1914. 



26. Parapsilocephala, Krober. (Fig. 25). 



This genus was proposed by von Krober for a species 

 from New South Wales and Victoria, which also occurs 

 in Tasmania. Von Krober distinguished the genus from 

 Psilocephala by the presence of a small yet high arch of
