Platypedia and Melampsalta, published in this Journal for June. 

 1920, five males collected by the American Museum Expedition, in 

 June, 1919. are recorded from Regnier and Lamar. To these may 

 now be added one male and three females from Lamar, June 17, 

 1900, recently sent to me for examination from the Colorado Agri- 

 cultural College. The entirely green Cicada from near the Rocky 

 mountains, which Thomas Say wrote about in 1825 in connection 

 with his Cicada parvnla, is supposed to have belonged to this species. 



Fossil Species. 

 Cicada grandiosa Scudder. 



This species was described and wing figured in the Bulletin of 

 the U. S. Geological Survey, No. 93, 1892, in an article entitled 

 " Some Insects of Special Interest from Florissant and other Points 

 in the Territories of Colorado and Utah.'' 



In the Bulletin, American Museum of Natural History, Vol. 30, 

 191 1, p. 76, Prof. T. D. A. Cockerel! comments upon this insect as 

 follows : '' This species was based by Scudder on a hind wing, which 

 was remarkable for its large size, and supposed to differ from true 

 Cicada in several venational characters. The wing, however, agrees 

 very nearly with that of the living American Cicada marginata 

 [marginalis Walker], and I believe represents a quite typical Cicada. 

 In March, 191 1, my wife and I found at the south end of Fossil 

 Stump Hill, Florissant, a rather poorly preserved upper wing of 

 Cicada, showing all the central area, including the forking of the 

 radius and cubitus, the median cell and the two large discal cells 

 above it. A\\ of this is perfectly typical for Cicada, and might almost 

 have come from a wing of C. marginata. The large cell in the 

 forks of the media has its side on the cell (median) below 12 mm. 

 and that on the cell above 10 mm. As the proportions agree exactly 

 with the upper wing which should go with Scudder's hind wing, it 

 seems safe to assume that they belong to the same species." 



Lithocicada perita Cockerell. 



Described and figured in the Bulletin Am. Museum of Natural 

 History, vol. 22, 1906, p. 457, from a plainly represented anterior 

 wing 23 mm. in length and 10]/, broad, showing almost complete 

 venation. The costal margin is very much bent near the apex of
