60 Transactions. — Zoology. 



The first posterior cell is closed. The larger specimens — 

 which I suppose to be the females — have no cliscal setae on 

 the middle segments, while the smaller specimens have well- 

 developed setae. 



Phorocera orasus. 



Tachina orasus, Walker, Cat. Dipt, in Brit. Mus., p. 741 

 (1849). Nemorcea orasus, Hutton, Cat. Dipt. N.Z., p. 49. 



Vertex dark-grey, the frontal band reddish-brown, grooved. 

 Face yellowish- white, with a dark reddish-brown spot on 

 each side. Second joint of the antennae and palpi tawny ; 

 the rest, as well as the proboscis, piceous. Thorax black ; 

 scutellum dark-fulvous. Abdomen dark-brown, not tessel- 

 lated. Legs black, the tibiae brown. Wings brown near the 

 base. Length, 8mm. ; wing, 6 mm. 



Hab. Auckland (Dr. Sinclair) ; Christchurch (F. W. H.) ; 

 Ashburton (W. W. Smith). 



The first posterior cell is open. There are no discal setae 

 on the middle segments of the abdomen. 



The South Island specimens may be distinct from those 

 from Auckland, but, as I have none from the latter place for 

 comparison, T keep them together for the present. 



Phorocera atrox, sp. nov. 



Head and cheeks brown ; the face white. Antennae, pro- 

 boscis, and palpi piceous. Thorax and abdomen greenish- 

 black ; the scutellum fulvous, or margined with fulvous. Legs 

 black. Length, 10 mm. ; wing, 8 mm. 



Hab. Napier (F. W. H.). 



The green colour of this species distinguishes it from any 

 of the others. The first posterior cell is open. 



Phorocera funesta, sp. nov. 



Vertex black, face grey. Antennae, proboscis, and palpi 

 piceous. Thorax, scutellum, abdomen, and legs black. 

 Length, 6-7 mm. ; wing, 5 mm. 



Hab. Christchurch (F. W. H.). 



The first posterior cell is open. Some specimens have no 

 discal setae on the middle abdominal segments, while in 

 others they are well developed. Perhaps this is a sexual 

 difference. 



Phorocera perniciosa, sp. nov. 



Vertex grey, the frontal band dark-brown ; lower face 

 white. Antennae, proboscis, and palpi piceous. Thorax 

 black, with green reflections ; scutellum fulvous. Abdomen 

 black, with greenish-blue reflections. Legs black, the tibia? 

 dark-brown. Length, 11 mm. ; wing, 9 mm.
