1. Tibicen cinctifera Uhler. 



Uhler, Trans. Md. Acad. Sci., I, p. 156 1892 {Cicada). 



This is recorded from New Mexico and northern California and 

 Mr. Davis has sent me specimens from Arizona, 



2. Tibicen montezuma Dist. 



Distant Biol. Centr. Am., Homop., I, p. 8, pi. 2, fig. 2, 18S1 {Cicada). 



This species is unknown to me. It ranges from Mexico north- 

 ward into New Mexico, Arizona and California as far as San Diego. 



3. Cacama crepitans Van D. 



Van Duzee, Trans. San Diego Soc. Nat. Hist., II, p. 45, 1914 {Proarna). 



I know this species only from its type locality at San Diego. I 

 have included the Rocky Mountain z'alvata in the key as it is likely 

 to be found in the mountainous portions of this state. 



4. Zammara smaragdina Walk. 



Walker, List Homop., I, p. 33, 1850. 



This species is included on the authority of Prof. C. W. Wood- 

 worth who reports a specimen labeled " San Diego." In the Museum 

 of Comparative Zoology at Cambridge.

Uhler, Entomologica Americana, IV, p. 81, 1881. 



This distinct little species seems to be confined to the southern

 on grassy hillsides from the last of March to about the first of July

 brush. It has a short peeping note which is difficult to locate. Dr. 

 Uhler's measurements were taken from a large specimen and may 

 refer to the form described below. In this species the front and 

 lower surface is conspicuously clothed with long pale hairs, the 

 anterior edge of the pronotum is concolorous and the elytral nervures 

 are largely pale brownish to the cross veins. The male uncus is
