T. D. A. COCKERELL. 237 



A small male Halictus from Adelaide (Schomburgk) , about 

 6 mm. long, has the robust form of a female (even robust 

 for a female!), and the clypeus all black; the flagellum is 

 ferruginous beneath, strongly crenulate in profile, the middle 

 joints about as broad as long. The specimen has been in 

 some liquid, and is not in condition to be properly described. 

 It is related to H. oxleyi Ckll., but differs at once by the 

 shiny mesothorax, etc.

 much pale hair, which is used to gather pollen, though not nearly so 

 much as the scopa of hind legs.

 bles, but abdomen very much broader at base, scape black,
