the penultimate. Radial cellule of moderate length ; the curved

Agrees in general form and coloration with A. longicornis, but is 

 smaller ; the antennae are scarcely so long, and with the joints 3-5 

 thicker and distinctly curved ; the radial cellule shorter, but with the 

 curved apical branch of the nervure longer in proportion to the basal 

 part. A. curvicor7iis may be known from it by the antennae issuing 

 from distinct tubercles, and distinctly longer, the fourth and fifth 

 joints more twisted, the radial nervure shorter and wider, the cubitus 

 shorter.
