!3G Mr. Westwood on the Famili/ Fulgoridie. 



nean and Fabrician Fnlgnne, including the well-known Ciiinese species Ful- 

 goni Candeluria, the European Fulgora europœa, &c. M'ere placetl in the 

 genus Fliitd. The character, however, upon which this separation was 

 founded cannot be maintained, since in F. Ccuulelaria and its allies the sepa- 

 ration between tiie forehead and the clypeus is strongly marked, and even in 

 F. tenebrosa the line of separation may be clearly perceived. 



M. Guerin in his description of the insects collected in the " Voyage de 

 Bélanger," gave another classification of the family, consisting of seventeen 

 genera ; amongst which Fluta and its allies are separated from Fulgora and 

 its allies, by the size of the prothorax, which is much narrower than tlie nieso- 

 thorax, and deeply notched behind ; whereas in the latter the prothorax is 

 " presque aussi large que le mesothorax, et très peu cchancré en arrière." 

 This last section consists of the following genera, thus tabularized :

By this arrangement, the character derived from the produced anterior 

 part of the head is made secondary to tliat of the form of tlie antennœ ; and 

 consequently we find that some of the species of Ap/iaiia, (.7. discolor, A. 

 fuscata, Gucr., A. nigro-muculata, Gray,) have the head produced into a re- 

 curved horn, as is also the case witli Fulgora recurro, which ought also to be 

 considered, according to tliis arrangement, as an Aplnnni. Burmeister has, 

 however, given another arrangement of these allied genera, v^hich in some 

 degree alters the limits of the genus Fulgora, and which is as follows : 



rt. Front of the head not rostrated. 



§ Second joint of the antenna* elongate-ovate. 



Forehead broader than long Poeocera. 



Forehead longer than broad or quadrate . . . Aphaua. 

 \ Second joint of antennœ globular.
