INDO -AUSTRALIAN SPECIES. 
Phora nudicosta n. sp. 
(Plate VIII. fig. 6.) 
Male. Length I‘3 mm. Thorax yellowish brown, head fuscous, 
pleura and legs pale testaceous, abdomen black with a testaceous band 
at the base which includes the entire first segment. A slender species 
with nonthickened legs and the habitus of Aphiochæta. Front one-half 
wider than high, lower row of frontal bristles consisting of four strong 
equidistant bristles, of which the lateral ones are close to the eye- 
margin. In front of these is an approximated much smaller pair of 
median reclinate bristles. Middle row placed rather high up ; ocellar 
row as usual. Ocelli not placed on a tubercle ; no trace of median 
frontal groove. Antennæ small, oval, yellowish fuscous, with an almost 
bare arista. Palpi yellow, slender, with stout bristles below, proboscis 
short and fleshey. Cheeks without any stout macrochætæ. Thoracic 
dorsum sub-shining, its hairy vestiture stronger than usual ; one pair 
of dorsocentral macrochætæ and only two marginal scutellar bristles. 
Scutellum about two times as wide as long. Abdomen black, except, 
the first segment which is testaceous; second and sixth segments elon¬ 
gate. Hypopygium with the large ventral lobe black and all the appen¬ 
dages testaceous. Front tibiæ with an external bristle at the basal third ; 
middle ones with a pair near the base and hind ones with a single 
bristle at the basal third. The four posterior tibiæ have each but a 
single spur. Wings hyaline, the veins fuscous. Costal vein extending 
only about two-fifths the length of the wing; entirely bare, without 
even any fine hairs and considerably thicker toward the tip. Third vein 
almost as thick as the costa, suddenly curved forward at the tip, fur¬ 
cate at a sharp angle very near the tip. First vein meeting the costa 
very obliquely just before the tip of the second. Fourth vein nearly 
straight basally, but broadly recurved at its apical fourth. Fifth and 
sixth nearly straight, seventh obsolete. Halteres pale, with a fuscous 
capitulum. 
One male. India: Matheran; 800 metres, July 8, 1902 (Biró). 
The present species could not be confused with any other. The 
peculiar configuration of the thick veins, bare costa, recurved fourth 
vein and slender legs with only single spurs on the four posterior 
tibiæ will serve to make it readily recognizable.
