and before the tip of the sixth longitudinal vein ; middle cross- ■ 
vein in the ^ situated somewhat before or exactly in line with 
tlie posterior cross-vein, in the ^ beyond the latter a distance 
equal to its length, always situated beyond the supernumerary 
cross-vein a distance equal to its length ; all about the same 1 
length ; first sub-marginal cell considerably longer and narrower j 
than the second posterior cell, the tips of the fork slightly conver- | 
gent, its base situated opposite that of the second posterior cell.

Ohs . — This is all the information about the genus given by | 
Meigen (Syst. Beschr. I.), while Macquart simply says, “ Palpi : 
very short 9 pointed, thick at the base.” From the single 9 
specimen before me I derive the following additional characters, I 
all of which have perhaps been already pointed out by modern 
Dipterologists, but whose works are not available in Australia. 
Head small, sub-globose, scarcely sunk in the thorax. Eyes 
reniform, a little emarginate at the insertion of the antennae, not 
quite contiguous on the front. Ocelli wanting. Palpi very short, 
densely scaled, 4-jointed ;* first two joints minute, the second 
larger than the first, third joint short, obovate, fourth joint about 
one third longer than the third, almost elliptical. Probo.scis 
slender, densely scaled. Antennae porrected, considerably shorter 
than the proboscis, 2-+ 12-jointed; first joint of the scapus large, 
globose, second pyriform, somewhat wider and about ^ longer 
* Should there be a minute terminal joint it is hidden in the scales, but 
to ascertain whether this be so the specimen might be sacrificed in the 
attempt.
