^. Feminae similis; tibiis intermediis etiam basi albido macu- 

 latis; segmento dorsali septimo albido; alls fascia basali sub- 

 obsoleta. 



Long. $, 7-8 mm. ; (J, 7 mm. 



$. Clypeus short and broadly truncate at the apex; antennae 

 about as long as the thorax and median segment combined, the 

 second joint of the fiagellum as long as the first and third com- 

 bined. Pronotum broadly arcuate posteriorly, not angulate; 

 scutellum convex. Median segment slightly convex, oblique, the 

 dorsal and posterior surfaces not separated, rather thinly covered 

 with short white pubescence. Abdomen subopaque; the apical 

 dorsal segment subtriangular, with a few rather long dark hairs. 

 Tarsal ungues unidentate. Cubitus of the hmdwing received at a 

 distance beyond the transverse median uervure equal to the length 

 of the transverse cubital nervure; submedian cell of the forewing 

 very slightly longer than the median; third abscissa of the radius 

 scarcely more than half as long as the second, the third cubital 

 cell shorter on the cubitus than the second. The fascia on the 

 basal nervure narrow, that from the radial cell broad, filling the 

 second and third cubital cells. 



(J, Tarsal ungues as in the female, but the tooth rather nearer 

 to the apex. 



Hab. Queensland, Mackay {Turner), November to 

 March. 



This seems to be midoubtedly congeneric with A. humilis, 

 Cress., from N. America, the type of Ashmead's genus. 

 The description of the genus, however, is far from accurate. 

 The cubitus of the hindwing in all species of the genus 

 known to me originates well beyond the transverse median 

 nervure, though not so far as in the present species. The 

 Indian Pompilus macidipes, Sm., also belongs to this genus. 



Genus Austrosalius, gen. nov. 



?. Head small, flattened, rather longer than broad; clypeus 

 very short, broadly truncate at the apex; the labrum exposed, 

 emarginate at the apex. Pronotum long, sometimes longer than 

 the mesonotum, sometimes a little shorter; median segment either 

 vertically or obliquely truncate, opaque and smooth, with a median 

 sulcus, the sides parallel, without tubercles; abdomen rather 

 narrow, convex, the sides of the four basal segments almost parallel ; 

 the transverse line on the second ventral segment visible, but not 

 deeply impressed. Fore femora very stout; fore tarsi without a
