'Related to H. philippinensis, Ashm., but easily separated 

 by tie much larger size and darker wings. It is also larger 

 than H. manilce, Ashm., with none of the greenish tint on 

 the head. The scutellum finely punctured all over readily 

 separates it from H. luzonicus, Strand. H. manilce. Strand 

 (not Ashm.), based on a poorly preserved specimen collected 

 long ago by Eschschcltz, has largely yellow legs, although it 

 is said to be a female. 



Halictus flindersi leucurus, subsp. n.

 (instead of dark fuscous) ; area of metathorax with stronger 

 better-defined longitudinal ridges. 



Distinguished from H, behri by the dark legs and man- 

 dibles ; from H. behri transvolans by the dark tibiae and tarsi 

 and angular tubercles.
