3/6 ENTOMOLOGICAL NEWS [Xov., 'oQ 



It may be added in closing that the rough species, as those 

 of the genera Kothrus, Xcoliodes, etc., are very sluggish in 

 their movements and for this reason are not noticed as quick- 

 ly as the more active, shiny ones. Further records will doubt- 

 less soon settle some of these interesting questions. 



Ticks on the California Ground Squirrel. 



BY WM. B. WHERRY AND F. CREIGHTON WELLMAN, 

 Cincinnati, Ohio, and Oakland, Cal. 



The important role played by a California, ground squirrel 

 (Otosperjiwphilus beecheyi) in the epidemiology of plague 

 in the United States makes a study of its parasites of particu- 

 lar interest. During June, July and August we found these 

 rodents to be heavily infested with ticks which occurred in 

 greatest numbers about the neck and ears. Specimens were 

 sent to Mr. Nathan Banks who has kindly given us the follow- 

 ing preliminary report: "There were two species of ticks; 

 one specimen is a common species in California known from 

 many hosts Dermacentor occidcntalis Neum. ; the other speci- 

 mens represent a new species of Ixodes, which I shall describe 

 as Ixodes aequalis. It is related to the /. angustus of Wash- 

 ington and Alaska, but has a larger and shorter shield, and 

 minor differences."
