fine and closely placed ; first vein ending a little nearer the tip of the 
third than the humeral cross-vein, tip of second close to third, the angle 
of furcation acute ; fourth vein evenly curved, recurved at the extreme 
tip ; seventh vein distinct. Halteres pale. 
Described from a single male collected at Callanga. Type in the 
collection of the Hungarian National Museum. 
This species is very robust, with somewhat the habitus of a Phora. 
It is notable for the strongly setulose legs, approaching the European 
melano cephala, ciliata and latifemorata in this respect. 
Aphiochæta tarsata n. sp. 
Male. Length °2 mm. Brownish, head black and wings brownish or 
yellowish. Head black, front wide, the bristles all strong, including the 
four proclinate ones. Ocellar tubercle and frontal furrow distinct. Antennæ 
rather small, the arista distinctly pubescent. Palpi small, yellow, the 
bristles black, normal. Thoracic dorsum reddish-brown, with a single 
pair of dorsocentral macrochætæ and four equally strong marginal scu- 
tellar bristles. Abdomen brownish black, more yellowish toward the base. 
Hypopygium small, brown, globose, the projecting lamella small with a 
short delicate bristle. Legs yellow, the hind tibiæ and tarsi darker. Front 
femora and tibiæ stout, the latter distinctly setulose externally, their 
tarsi widened and flattened, especially the first and second joints, the 
first being wider than the tibia. Middle and hind legs rather slender, 
their tarsi normal, the tibiæ of the hind pair quite strongly setulose. 
Wings large, the costal vein long, much as in aurea Ald., but the cilia 
are much longer, and the fourt vein is much curved at the base and 
straight to the apex which is recurved. The cell formed at the furcation 
of the third vein in also larger. Fifth vein almost straight, seventh 
distinct to the margin. Halteres blackish brown. 
Described from a male specimen collected at Callanga. Type in the 
collection of the Hungarian National Museum. 
This species approaches closest to A. aurea Ald., from which it 
differs by its peculiar front tarsi in the male, longer costal ciliation and 
different wing venation. 
Aphiochæta delicatula n. sp. 
Male. Length 1*4 mm. Small, delicate yellow species, with darker 
abdomen. Head yellow, the front darkened above. Ocellar tubercle and 
median furrow present. Chætotaxy normal, except for the median pair
