II. The Characters of Otiocerus and Anotia, two new Genera 

 of Hemipterous Insects belonging to the Family of Cicadiada : 

 with a Description of several Species. By the Rev, William

1 ii e extensive family of Cicadiada, consisting of the two Lin- 

 nean Hemipterous genera of Fulgora and Cicada, although my 

 learned friend M. Latreille has done much towards reducing 

 it to order, is by no means in a state of arrangement so perfect 

 as to preclude further improvement. Considering the great 

 beauty of some species, the almost incredibly singular and gro- 

 tesque form of others*, and the celebrity which, from the earliest 

 ages, has been attached to a third tribe of them+, it is wonder- 

 ful that this family has not been more attentively studied, and 

 its genera more accurately distinguished and defined. 



The characters afforded by these animals for such distinction 

 are numerous and striking. Not to mention the promuscis J ; the 

 situation, length, and composition of the antennee ; the presence 

 or absence of the stemmata or ocelli, and their number and posi- 

 tion ; the shape and place of the eyes ; the gence ; the front and 

 ckfpeus, or rather nasus ; the shape of the thorax ; the figure, vein- 

 ing, and substance of the elytra and wings ; and, to name no 

 more, the anal apparatus of the sexes, furnish a variety of excel-
