Genus Croapa, Linneus, Stal.

This*is one of the oldest names in the order and has suffered so 
many changes by the creation of new genera that it would be unprofit- 
able to trace back its history. Taking the changes of the last quarter of 
a century, we find that in 1866 Stal added Leptopsaltria, Cosmopsaltria, and 
Pomponia tothe Dundubia group. The Cicada group including Fidicina 
was increased in 1861 (A.S. H. F. (4 sér.) i, p. 613) by Psaltoda, Cryp- 
totympana, Tympanoterpes, and Selymbria, and, in 1864, by Proarna. 
In 1862, Stal (Rio. Jan. Hem. p. 19) distributed the species of Cicada 
proper amongst the subgenera Cicada, Taphura, Parnisa, Calyria, and 
Prunasis. All of these were raised to the rank of genera in 1866 (Hem. 
Afric. iv, p. 8) and, excepting Cicada, were thrown into the Tibicen group. 
To the Cicada group were added Henicopsaltria, Nosola, and Emathia, in 
1866 ; and to the Tibicen group, Henicotettix in 1858; Pydna, Stagira, Cal- 
lipsaltria, and Tympanistria, in 1861; and Rustia and Beturia, in 1866, 
In 1870, Stal still further divided the species of his restricted Cicada 
in establishing the subgenera Chremistica, Macrotristia, Cicada, and 
Diceroprocta. I doubt much whether any of those Indian species which 
still bear the generic name Cicada really belong to that genus: if 
they do, they belong to the subgenus Cicada, which has the sides of 
the thorax anteriorly without a lobe ; the sides of the last dorsal segment 
in & posteriorly unarmed, very often produced in an acute tooth in the 
middle ; the sixth ventral segment in Q broadly, angularly sinuated at 
the apex; and the interior ulnar vein straight or but slightly curved. 
This question can only be settled by an examination of the types.

termediate coxe and the antenne, black: anterior lobe of pronotum
