PHORIDÆ FROM THE INDO-AUSTRAI IAN REGION. 
547 
Hypopygium whitish pollinose, the lamella pale yellow, without any stout 
bristles ; the ventral segment just before the hypopygium with a trans¬ 
verse row of bristly hairs. Legs stout, coxæ and femora very dark brown, 
tibiæ and tarsi brownish testaceous ; posterior femora very stout, sub- 
ciliated with black hairs below at base. Hind tibiæ weakly setulose. Wings 
subhyaline, with a faint tinge of dull yellowish ; veins brown ; costa 
reaching just to the middle of the wing, its cilia long and well separa¬ 
ted ; first vein ending distinctly nearer to the humeral cross-vein than to 
tip of third ; cell at furcation of third vein moderately large ; fourth vein 
evenly curved, faintly recurved at base ; fifth nearly straight, ending much 
nearer to the wing tip than the fourth; seventh vein distinct. Halteres 
castaneous, paler at tips. 
One male from Sattelberg, Huon Gulf, New Guinea (Biro, Sep¬ 
tember 1898). 
A rather robust species coming nearest to the European A. rufi- 
cornis Meig. from which it differs by the absence of the tufts of bristles 
at the sides of the second abdominal segment, by the different wing ve¬ 
nation, and hypopygial structure. 
Aphiochæta planifrons n. sp. 
Female. Length L5 mm. Black, legs brown, front without ocellar 
tubercle or groove. Head rather large, front convex, shining black, spar- 
selly punctured, quadrate, the vertex not elevated, no ocellar tubercle or 
frontal groove, the ocelli more widely separated than usual, the upper 
pair being twice as far from each other as from the eye margin. Four 
proclinate bristles present, the upper pair widely separated ; lower cor¬ 
ners of front each with a pair of reclinate bristles ; next row above cur¬ 
ving upward; ocellar row nearly straight. Antennæ oval, reddish brown; 
arista pubescent. Palpi small, light yellow, with strong bristles. Post¬ 
ocular cilia strong ; each cheek with two downwardly directed macro- 
chætæ. Dorsum of thorax shining piceous, with one pair of dorsocentral 
maerochætæ and two marginal scutellar bristles. Abdomen black, sub¬ 
shining, slightly hairy at tip ; venter black; genitalia testaceous. Legs 
stout, anterior pair pale testaceous, their coxæ and femora a little darker; 
middle pair dark testaceous, their femora darker, distinctly thickened, 
their tibiæ finely setulose externally. Hind legs fuscous, the femora 
considerably thickened and ciliated, on the apical half below with black 
hairs ; the tibiæ strongly setulose. Wings hyaline, the veins brown ; costal 
vein reaching to considerably beyond the middle of the wing, its cilia of 
medium length and closely placed; tip of first vein nearer to tip of
