small bristles along the outer side ; middle ones with a pair at basal 
third and an external one just before the tip ; posterior pair with a single 
one at basal third and one just before tip. Wings hyaline, the costal vein 
reaching distinctly beyond the middle, its cilia ve^y fine and short; 
mediastinal vein absent; first vein ending twice as far from the humeral 
cross-vein as from the tip of the tird ; furcation of third very near its 
tip, the cell thus formed extremely small. Disc of wing with only three 
distinct light veins ; the fourth longitudinal rather evenly and but slightly 
curved; fifth almost straight; sixth faintly sinuate; seventh obsolete. Hal¬ 
teres yellow. 
Female. This sex differs only by its slightly larger and more strongly 
bristly palpi and by the presence of a much weaker pair of bristles on 
the scutellum in addition to the strong pair. 
Described from one male and two female specimens from Sattel • 
berg, Huon Gulf; Friedrich- Wilhelmshafen, and Moroka (1300 metres), 
New Guinea. 
In general appearance this species reminds one of the North Ame¬ 
rican P. incisuralis Lw., but is widely distinct. It is evidently closely 
related to Phora (Dorniphora) Dohrni Dahl, but differs in color and in 
the chætotaxy of the hind legs.

There is in the collection a single male from Sattelberg, Huon Gulf, 
New Guinea (Biró, 20—30. IX. 1898) which is as typical as any specimen 
I have seen. The species was described from the West Indies and may 
possibly have been introduced into one or the other of these localities, 
although there is a closely related species, P. incisuralis Lw. in the Uni¬ 
ted States and another, P. Dohrni Dahl occurring in the Bismarck Archi¬ 
pelago. 
This latter species was made the type of the genus Dorniphora by 
Dahl (SB. d. Naturi. Freunde, Berlin, Nr. 10, p. 188), but his generic 
division is scarcely tenable since it rests solely on the elongated proboscis 
of the female and the more or less complete absence of the mediastinal 
vein of the wings. It may very well form a group of the genus however, 
containing the four species enumerated in the following table :
