A few further species are based on extensive series ofthese flies that were taken in the vicinity of Hollandia,

The types of the Cheesman materials are preserved in

The present fly is very different from the only other
Australasian member of the genus so far described,
Brachypremna tigriventris Alexander, of North Queensland,differing in all details of coloration of the body, especiallythe thorax and abdomen, and in the venation. The
great centre of distribution for the genus is Tropical
America and it seems evident that the Australasianspecies must be relicts of a former wide-spread Pantropical fauna. This is substantiated by the occurrenceof an undoubted member of the genus, E. gurnetensis(Ckll.), in the Bembridge beds, at Gurnet Bay, England,of Lower Oligocene age. I t is of interest to note that
despite the great antiquity of the group as thus shown,
all recent species show the subobliterated tips of the outer
medial veins of the wings.

Dolichopeza (Nesopeza) prcesultator, sp. n.
General coloration of thorax whitish grey, conspicuously
patterned with brown; frontal prolongation of headbrownish black; palpi black, the tip narrowly yellow;
