the nymph of a species of Cicada. ‘There are several speci- 
mens in the collection of the British Museum. 
This species is extremely variable in form, but in its most 
Perfect state has a subglobose head and proliferous stem; 
sometimes the terminal head is not developed and the stem 
_ 5s terminated by a number of little heads, which form a 
r as in a recorded variety of Sph. militaris; sometimes 
_ the stem is branched above, each branch being terminated by 
. 4 little clavate head; sometimes a single head only is 
3 developed but tuberculated, and in this case there are no 
. Proliferous processes on the stem ; and occasionally not only 
the stem is even, without any proliferous processes but the 
head instead of being subglobose is absolutely linear as in the 
x two following species, I have in vain examined specimens 
both dry and preserved in spirits in the hope of finding 
Perfect asci, but the perithecia, though tolerably well formed, 
_ Sontained merely a few threads which broke up into short - 
Cylindrical portions. These are probably imperfect strings 
. 9f sporidia, and if so differ materially from those of Sp. 
 fhtomorrhiza and Sp. Robertsii. The greater part of the 
_ gures in plate 5 of Fougeroux’ Memoir belong probably to 
* 8p. entomorrhiza. The substance figured on a perfect 
: Cicada is a secretion as Mr. Gray showed me in several 
. ‘Pecies in the British Museum.
