The situation of the antenna' of the insect from which I Iiavc 

 formed this genus, agrees with that of Fulgorn; but in all tlic 

 genuine species of the latter their second joint is much larger 

 than the first, globose, and covered with papillee : whereas in 

 AchUus it is not remarkably larger than the first, is rather taper- 

 ing, and without papillae. The labrum also is not separated from 

 the cljpeus, except on the sides, by any suture or even impressed 

 line; the thorax a good deal resembles that of Ftilgora, but it is 

 more completely obtusangular.
