In the original description a female is reported from Nucla, 

 Colorado, Sept. 7, 1907 (C. T. Trueb), collection U. S. National 

 Museum. The following localities can now be added : Bondad, June

 bush, oak, sabina, pinyon, cottonwood, etc.'' (Dr. Lutz), Am.

 Putnam in his '" Remarks on the Habits of Several Western Cicadae,'' 

 Proceedings, Davenport Academy of Natural Sciences, March, 1881,
