In the species of Cicada observed, there are 3 pairs of thoracic, and 7 
pairs of abdominal stigmata. The outer wall of the sonorous cavity 
belongs to the second abdominal segment.

Gryllodeon. Denk. Ak. Wien, xxxvi. 2, pp. 273-290, pis. i. & ii. 
Pages 274-284, and pi. i., refer to Cicada. The tympanal membrane 
is a modification of the margin or lateral part of the first dorsal segment, 
and there is no trace in the $ (of C. plebeia, at least, upon which the 
author’s observations were made) of any structure corresponding to the 
male organs of sound. The muscular and other anatomical systems are 
discussed, with the result that entirely heterogeneous matters appear to be 
developed from one and the same place, and that there is not the least 
analogy between the homology of the tympanum muscle of the Cicada 
with that of the Acrydiidcc.
