knees red ; front dull, shining at extreme sides ; mesothorax shining, especially 

 posteriorly, the scattered punctures extremely minute and hardly visible ; area of 

 metathorax dull, covered with fine wrinkles ; venter of abdomen with long white 

 hair, in which pollen is collected. 



Microscopical characters : Front as densely punctured as possible ; meso- 

 thorax minutely tessellate, with scattered piliferous punctures ; area of metathorax 

 irregularly reticulate ; first abdominal segment finely punctate ; second with basal 

 tliird j)unctate, the rest transversely striate ; hind spur with few long teeth. 



Hab. : Bribie Island, type taken 2.11.13 {Hacker 117). Another, with same 

 data, bears number 167. Close to H. blackburni Ckll., but mesothorax and metathorax 

 different. The area of metathorax is entirely different from that of H. sturti Ckll. 

 Among the Tasmanian species it falls near the much larger H. furneauxi Ckll.

H. bursarice is a member of the group which includes H. cambagei, H. repertus, 

 H. isthmalis, and H. repertulus. 



Halictus repertulus n.sp.

 white hair, not forming distinct bands or spots on the abdomen, though there are 

 small and thin, hardly noticeable, patches at lateral bases of second segment ; man- 

 dibles with a small cream-coloured spot in the middle, and the apical part red ; clypeus 

 shining, minutely and feebly punctured, nearly the apical half very pale yellow ; face
