into an acute spine. Black, with white pubescence on head and

 lines between antennae, margins of pronotum narrowly, tegulae 

 and an oblique line above them, a longitudinal median line on 

 posterior half of mesonotum, a spot in middle and one at each of 

 the anterior angles of scutellum, a transverse line on postscutellum 

 and an oblique spot on each side of it, a small spot near middle 

 of median segment, a rather larger one at apex and one on each 

 side, three small spots on mesopleurse, a transverse spot on each 

 side of first abdominal segment and an interrupted narrow band 

 near apical margin of segments 2-6 above and beneath emarginate 

 posteriorly creamy-white ; pronotum, disc of mesonotum and 

 scutellum, mesopleurse and legs ferruginous. Length 9 mm. 



Hab. — Cooktown, Q. (Turner). 



Taken in October flying with a colony of Bembex.

 points of difference.

 transverse line near base. Hypopygium produced into an elongate 

 spine, stout at base, with a small spine on each side. Black; 

 mandibles, clypeus, interantennal carinae, margins of pronotum, 

 tegulae and a line above them, mesopleurae in front, a quadrate 

 mark on mesonotum, a transverse spot on scutellum and a small 

 one at each of its basal angles, postscutellum, a spot at apex of 

 median segment and a longitudinal mark on each side of it, a 

 narrow curved band strongly emarginate posteriorly on each side 

 of first abdominal segment, a broader band on segments 2-6 

 narrowly interrupted in middle and emarginate on apical margin
