I have some doubt as to tlie correctness ot" my identifica- 

 tiou of these specimens. They agree fairly with Kohl's 

 dfscriptiou in structural points, but the longitudinal groove 

 on the scutolhitn is very faint. The abdomen is bU\ck, with 

 tiie exception of the sixtli segment, the apex of the fifth and 

 the apex of first ventral segment.

Identical with the typical form from Aru. I consider that 

 ahditus, Kohl, is merely a local form of this species, whicii 

 ranges from India to N. Queensland.

I am doubtful if these specimens are correctly identified, 

 the petiole being distinctly shorter and the wings darker than 

 is usual in males of nigellus, which has a very wide range in 

 Australia and E. Asia.
