Body brown. Legs and antennae yellowish-brown. Eyes reniform, 

 dark red-brown in colour. Antennae '63 mm. Seven jointed. Joint 

 one short subpyriform; joint two stout, oue and a half times the length

 seven equal, each about half the length of joint three. Vasiform orifice 

 obovate, operculum small ; anterior and posterior margins flat, lateral 

 margins curving outwards from anterior margin and incurving to meet

Description of Aleurodidas 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 eugenise 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. loagicornis Zehnt. 

 Their descriptions will be given in Part II.
