The long round petiole of the abdomen, which is 

 sometimes composed of the 1st and part of the 2nd 

 segments, is a character by which this genus may be at 

 at once recognised. Miscus used to be considered a 

 distinct genus on account of the petiolation of the 

 3rd submarginal cell ; but this is a very variable 

 character, as I have sj)ecimens of Miscus with the cell 

 simply triangular, and no petiole; this being the 

 case, I have considered it as synonymous with Ammo- 

 phila.
