A genus distinct from all other Aeschnseid g-enera by the posi- 
tion of the sectors of the arcukis above the middle of the arculus 
at their origin. Two species are found in the Transition and 
Austral zones. A. junius and A. longpipcs. They are readily sep- 
arated by the presence of a spot on the frons above in jituius, ab- 
sent in longpipcs.
