The two oriental species may be distinguished as follows : —

lyong. 7 mm. b Ceylon, Ceram, Dorey (Papua), Batjan, 

 Philippine Islands, Ramai and Andai in Papua (4 b b taken 

 February 1875) also June and August 1872. Osten Sacken records 

 the species as C. obesa Wlk., adding " very like azurea Gerst.," but 

 mentions differences He again (Dipt. Phil. Is., 1882) expresses 

 doubt as to the identity of this species with 3 specimens ex- 

 amined by him from those Islands collected by Dr. Carl Semper. 



A. auricollis Big.

I can find no reference to the description of this species, 

 which appears distinct from azurea Gerst.
