DIPTERA OF AUSTRALIA, 
seems to me to belong to this species, but is too abraded to 
satisfactorily decide. I do not know of any other captures of 
specimens of this genus in Australia, and I have never yet had 
the fortune to see a living example of these evidently scarce, and 
extremely magnificent insects.

Head small, almost globose, situated moderately deep in the 
thorax. Eyes lunular, emarginate at the insertion of the antennse, 
approximate above. Ocelli wanting. Palpi porrected, clothed 
with scales ; longer* than the antenme in the six-jointed, the 
last three joints haiiy ; first two joints short, third long and 
slender, fourth the longest, clavate, fifth and sixth about equal 
length, the fifth longer than the sixth or the latter longer than 
the fifth ; in the ^ very short, five-jointed ; first joint rather 
longer than the second, membranous at the base, second small, 
third clavate, fourth longest and stoutest, fifth extremely small, 
nipple-shaped or gemmiform. Proboscis long, slender, densely 
clothed with scales, straight or a little bent. Antennse por- 
rected, about the length of the thorax, shorter than the 
proboscis, 2- -|- 12-jointed, first joint of the scapus large and 
globose.; in the ^ second rather longer and stouter than the 
first flagellar joint, whorled with very long hair towards the 
apex ; the ten following flagellar joints short, fusiform, whorled 
in the middle with very long hair, the penultimate joint greatly 
elongated beyond the whorl, terminal joint long, shorter than the 
last, slender like the continuation of the last, with a few moderately 
*Meigen, Macquart and Curtis all say “longer than the proboscis ” in 
the <J , but 1 do not find this to be the case in every species.
