A Catalog of the California Aleyrodidae 



and the Descriptions of Four 



New Species 



By Donald D. Penny 



Introduction 



This paper consists of a list of the ah-eady described species of 

 Aleyrodidae, or white flies, taken from the State of California, and 

 a record of their food plants and localities together with the descrip- 

 tions of four new species. 



The writer has not attempted to give a systematic arrange- 

 ment of the family in this paper but has laid much stress on the 

 completeness of the list of food plants upon which the different 

 species have been taken in order that from a knowledge of the food 

 plants the family will be more readily accessible and at the same 

 time may be kept up to date in respect to the host records. 



In the collecting of specimens the writer has not been con- 

 fined to any one section of the state but has taken and received 

 specimens from a wide range of localities, including sections of 

 both high and low elevation, from the extreme north to the extreme 

 south of the state. This has resulted in the recording of some new 

 hosts for the already described species as well as the finding of 

 the four new species herein described. 



The writer desires to thank Professor E. 0. Essig for the 

 many specimens given and other kind assistance rendered during 

 the preparation of this paper. 



Paratypes of the author's new species have been deposited 

 with the collection of the California Academy of Sciences, Golden 

 Gate Park, San Francisco, California.
