Description of Aleurodidae previously described from the Indian 

 Region. 



Only a few species of this family have been described so far from 

 India and Ceylon. For the sake of convenience I have thought it ad- 

 visable to include the full descriptions. 



The following species have so far been described. 



Aleurodes eugenic Mask. 



Aleurodes eugenise Mask. var. aurantii Mask. 



Aleurodes barodensis Mask. 



Aleurodes cotesii Mask. 



Aleurodes piperis Mask. 



Aleurodes nubilans Buckton. 



Three other species in all have been described from the Oriental 

 Region. A. gossypii Fitch, A. lactea Zehnt. and A. longicomis Zehnt. 

 Their descriptions will be given in Part II. 



Aleurodes eugenise Mask.
