B. saltusans n. sp.

♂. Black. Head black; eyes distinctly hairy, dichoptic, the margins angulated just above the antennae (fig 20); front slightly narrowing toward the antennae, shiny black, and distinctly hairy. Antennae blackish-brown, situated below middle line and, if anything, a little longer than half the width of head, 1st joint elongated, the 2nd about two-thirds as long as the 1st, and both bristly on the upper side; all but the first 2 segments of flagellum missing; 1st segment nearly as long as 2nd antennal joint but broader, the 2nd segment shorter, and both distinctly hairy. Face dull black with distinct brownish hairs except beneath the antennae where it is bare and shiny black; oral margin shiny bluish-black; proboscis brownish; palpi 2-jointed and blackish-brown, and both presenting a peculiar segmented appearance; 1st joint bristly, the sides notched (fig. 21), from which notches arise long bristle-like hairs, 2nd joint more or less clavate, apparently

divided into 5 segments from the anterior corners of which (except of the 1st) arise bristle-like hairs; the 1st of these segments is bare and brown in colour, the remainder having a vestiture of dense light-brown pile, the apical terminating in a pair of indistinct and short brown bristles. Posterior orbits broad, black, and hairy; occiput shiny black and flat.

Dorsum and scutellum shiny black with a covering of greyish hairs; scutellar spines black, short, and indistinct; pleurae brownish and slightly hairy; halteres brownish.

Wings shorter and blunter than preceding species, clouded with brown, but darker anteriorly than posteriorly with clear intercellular spaces; stigma darker brown but a clear space separating the pigment from the 2nd vein; veins brown; all the veins on posterior half excepting the 5th longitudinal weaker than those on anterior half; subcostal cell more or less clear except for a cloud along auxiliary vein as far as bend at apex; a clear space at the anterior apical corner of 1st basal cell, the colour also being separated from the 1st vein; in the 2nd basal cell is a more or less clear space apically, while these two basal cells are separated by a clear line, the vein being here obsolete; clearer spaces at apex of anal cell, in discal cell, in the posterior cells (that of the 1st posterior cell being in the form of a median line), and in the 1st submarginal cell at the costa. Costa curved outwards along costal cell, which is thus somewhat widened; auxiliary vein sinuated, 1st section of 3rd vein about twice as long as anterior cross-vein; 3rd vein slightly down-curved along posterior branch; the anterior branch arising at right angles and strongly curved to the costa (fig. 22); apex of discal cell slightly beyond the line of end of 2nd longitudinal vein; the 1st, 3rd (except anterior branch), 5th, and 6th longitudinal veins distinctly bristly.

Legs hairy, slightly stouter than in preceding species; femora and tibiae dark brown, their tarsi brown except proximal portions of protarsi and epitarsi which are greyish-brown; protarsi not quite half as long as the whole joint; posterior femora, tibiae, and protarsi perceptibly thickened; middle and anterior legs more hairy than the posterior, and the lighter portions of the tarsi of these legs somewhat darker than the posterior.

Abdomen ovate, composed of 7 segments, broader than the thorax, apically truncated, and brown in colour. Genitalia (fig. 23) more or less withdrawn; composed of an outer pair of 2-jointed, hairy, claw-like styles (a), while toward the base of each on the inner side is a small pointed and bare chitinous structure; between these outer claws is a pair of shorter, flat, and pointed hairy structures arising from a dome-shaped piece (b). The genitalia were damaged when mounting, so that a fuller account cannot be given.

♂. Length, 4 mm; wing, 4 mm.

Habitat — Wallacetown, October. Captured in the bush by Mr. A. Philpott.

The chief characters which separate saltusans from the preceding species are the angulated eye-margin, hairy flagellum, and hairy legs, the 4 bristly veins, and the position of the apex of the discal cell beyond the end of the 2nd longitudinal vein. Doubtless it will have to be placed in another genus.
