The situation of the antennæ of the insect from which I have 
formed this genus, agrees with that of Fulgora; but in all the 
genuine species of the latter their second joint is much larger 
than the first, globose, and covered with papillæ : whereas in 
Achilus it is not remarkably larger than the first, is rather taper- 
ing, and without papilla. The labrum also is not separated from 
the clypeus, except on the sides, by any suture or even impressed 
line; the thorax a good deal resembles that of Fulgora, but it is 
more completely obtusangular. ;
