Oxystoglossa decor ata^ Smith. 



Type ? . Jamaica. 



Second submarginal cell very narrow; eyes emarginate; liind 

 spur of hind tibia strongly curved, simple. 



Rhathymus quadriplagiata^ Smith. 



Mexico. 



This species shows an extraordinary resemblance to ScoUa 

 guttata, Burm. Ashmead gives the maxillary palpi of Rha- 

 thymus as 4-jointed ; but this must be a slip of the pen, as 

 they are actually absent, as Gerstaecker and others have stated. 

 In Eurytis funereus, Sm., which looks like Rhathymus atra, 

 Sm., they are 3-jointed (the first and third joints very short, 

 second very long), not 1-jointed as Smith states. This 

 observation is based on Smith''s type. 



XXX. — The Halictine Bees of the Australian Region. 



By T. D. A. CUCKEKELL. 



The Halictine bees of Australia were studied and described 

 many years ago by Mr. F. Smith : since his death they 

 have received practically no attention ; and owing to the 

 brevity of the published descriptions and the complete 

 absence of tables for identification the recognition of the 

 species has seemed difficult. The following tables and notes 

 are based on an examination of Smithes types in the British 

 Museum, and it is hoped that they will make it easier 

 for entomologists to further elucidate the subject. There 

 can be no doubt that any resident of Australia who will collect 

 and study these bees will find many new species.
