Some observations upon this species, communicated 



by J. P. Wild, a German resident of Baltimore, to Mr. 



Becker, of Paris, have been published in the Ann. Soc. 



Ent, France 2d ser. Bullet, v. 10, 1852, p. XVIII., in 



which the name primiosa is confused so as to be spelt 



hruneosa. 



The descriptions given by Linnaeus are too short to 

 separate this from several other species inhabiting the 

 same localities with those cited by that author ; so that 

 we are necessitated to consult later Grerman and Swedish 

 authorities for more adequate information. Accordingly, 

 we find by reference to Dr. Grermar, in Silbermann's 

 Hev. Ent. v. II., p. 64, that the true C. tibicen Linn., is 

 the common form, which is figured by Stoll in his 

 Cigales, fig. 13. We are also informed by the same 

 author that the Cicada opercularis Oliv. was described 

 from this figure of Stoll, and consequently that the 

 latter name is a synonym of the Linnaean one. 



The description of Linnaeus, Mus. Lud. Ulr., p. 160, 

 embraces the characters of two or three species, one of 

 which appears to be the C. mannifera Fab., but the 

 figures of Merian, Brown and Seba, cited in the same 

 place, represent species very different from the true C. 



o 



tibiceii. More recently Dr. Stal has examined a type of
