Fam. Dolichopodidæ.

The males of this family bear sexual ornamentations on the legs, head, the third joint of the antennæ, as well as on other parts. The species of this division are small.

Psilopus mobilus.

Very common in the bush at Taieri Mouth during January (1908). These flies were found, basking in the sun, on tree-trunks. I captured only two at Murdering Beach in January (1909), and these were resting on rushes which grew in a swamp behind the sandhills.
