March, 1921.] DaVIS : RECORDS OF NORTH AMERICAN CiCADAS. 3 



Lately three males and three females have been examined, collected 

 about five miles from El Paso, Texas, June 23, 1919, by Mr. H. H. 

 Willis, and kindly sent to me by Mr. E. R. Sasscer of the Federal 

 Horticultural Board. In the Academy of Natural Sciences, Phila- 

 delphia, there is a male from Langtry, Valverde Co., Texas, Aug. 

 24, 1912, 1,050-1,550 ft., collected by Rehn and Hebard. 



On plate 4, figure 25, Genera Insectorum, there is a figure of a 

 cicada said to be cinctifcra, but the fore wing is much too broad in 

 proportion to its length, as will be noted by comparing it with the 

 figures on the plate accompanying this article reproduced from 

 photographs of the Mesilla male, and one of the El Paso females, 

 referred to above. 



Another species heretofore confused with cinctifcra, and ap- 

 parently more common than it, is here described as new. 



Tibicen apache new species. PI. I, figs. 4, 5 and 6. 



Type male and allotype female from Florence, Arizona, July 29, 19 17 (Dr. 

 H. H. Knight). Davis collection. 



Resembles Tibicen cinctifcra (Uhler), but has sharper pointed opercula, 

 the outer sides of which are not parallel, but converge; is without the central 

 pruinose spot at the base of the tergum, and instead of having the dorsal part 

 of segment eight all pruinose, the whitened area is reduced to two spots with

a black space between. In the allotype the plates that correspond to the 

 opercula of the male, are sharper pointed than in cinctifcra, the double notch 

 in the last ventral segment is usually deeper, the terminal spine is more robust, 

 that is, has a broader base, and the abdomen is less tapering at the extremity. 

 In the three types of Uhler's cinctifcra in the United States National Museum, 

 the costal margin of the fore wing is bright orange to the end of the radial
