Division M e l A m p s A L T A r i A. 



This division, though at present containing only three 

 genera, embraces a large number of species. It is easily 

 recognized by the venation of the tegmina, in which the 

 bases of the upper vein to lower ulnar area and the lower 

 vein to radial area are fused or the first emitted at some 

 distance from the base of the second. The distribution of 

 the Melampsaltaria is in the Old World, though there is a 

 Nearctic representative ; but it is in Australia where the 

 greatest number of species is found and where the head- 

 quarters of the division is clearly indicated.

Type, M. mudva, Germ. [Cicada). 



Considerable difficulty appertains as to the nomenclature 

 of this genus. It was first named by Amyot (scarcely 

 described), supra, and takes precedence of the name Cica- 

 detta which he used on a succeeding page. Kolenati described 

 the genus, but had previously also described Cicadctta, 

 which, if we take Kolenati as the real founder, must have 

 priority. However, I follow Sial, Karscli, and otlier writers 

 in giving the name Melampsalta precedence, as given by 

 Amyot. 1 have failed to separate Cicadetta from Melam- 

 psalta : if we com[)aie the type of the first, the Cicada luontana^ 

 iScop., with the type of Melampsalta [supra), a difference 

 appears in the position of emergence of the upper vein of the 

 lower ulnar area j but much as 1 endeavoured to thus break
