Much like A. elegans, but is at once distinguished from that species 

 by the abdominal segments being beautifully margined with violaceous.

 I have two % specimens before me which differ from the above only 

 by having the head and thorax dull black, very faintly tinged with 

 obscure bluish, instead of being brilliant blue-green. It is probably 

 only a variety.
