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 hair)' ; 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. C4enitalia (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 



c?. Length, 4 mm. ; wing, 4 mm. 



Habitat. — Walla cetown, 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. 



B. caliginosa n. sp. 



o . Eyes distinctly hairy, not broadly dichoptic ; front shiny black and 

 distinctly hairy ; antennae blackish-brown, about the length of the width 

 of one eye and situated on the middle line ; 1st joint not much longer
