In the original description in 1S77. Uhler states that the types 

 were "collected in the vicinity of Clear Creek. Colorado, hy Mr. [. 

 Duncan Putnam." In the Proceedings of the Davenport Academy 

 of Natural Sciences, Vol. 3, March, 1881. there are some "Remark- 

 on the Hahits of Several Western Cicad.-e." hy Mr. Putnam, made 

 at the meeting of January 31, 1879, as follows: "Cicada putnami 

 Uhler (Vol. 2, Plate 4. figs. 3 and 4) I have collected only ujjon one 

 occasion. July 2, 1872. It occurred in considerable numbers on some 

 small aspen trees growing close to tlie water of Clear Creek, between 

 Floyd's Hill and Idaho Springs, Colorado. The male makes a very 

 faint chirp, differing entirely from any other Cicada I have ever 

 heard. This species does not appear to have been collected since." 



Specimens from the following localities are recorded in the 

 Journal, N. Y. Entomological Society, for June, 1920: Fort Collins. 

 Boulder, Bear Creek in Jefferson Co., Chimney Gulch, Golden. 

 Platte Canyon, Manitou. Canon City. Alamosa. Mesa \'erde in 

 Montezuma Co., Durango, Bondad, Pagosa Springs, and Starkville. 

 The dates of capture are from May 13. 1901, at Chimney Gulch 

 (Dyar and Caudell). to July },-j. 1919. at Mesa Verde at an 

 elevation of about 7,300 ft. 



All observers report the notes of the several species of Platypedia 

 as a series of short clicks, and Dr. Lutz states that those he col- 

 lected at Starkville produced a "clicking .sound; about eight clicks, 

 rapid at first, but slowing."
