Introduction. 



The present paper is made up of descriptions of three 

 new species of Coccid^, or scale insects, from California, 

 with some notes on a little known form. The writer's 

 thanks are due Professor T. D. A. Cockerell, for his cour- 

 tesy in examining specimens, and for his assistance in their 

 determination.
