Introdüction 



The folloAving puper preseiits a review of the present 

 knowledge of the white ñies, or Aleyrodidae, of South 

 America. The stiuly is based not only upen the Avork of 

 other students of the South American fauna, but also upon 

 the extensivo collections of the Burean of Entoraolgy and 

 the U. S. Xational Museum. These collections have made 

 available, in the past two decades a wealth of material and 

 have formed the foundation of an exhaustive monographic 

 stiidy of the family by Dr. A. L. Quaintance and the sén- 

 ior author. Free use has been made of the published por- 

 tions of that monograph und the writers are iudebted to 

 T)r. (Quaintance for his many siiggestions ('"'). 



It has been the writer's aim to bring up to date our 

 knowledge of South American Aleyrodidae and to prepa- 

 re a work that might be used as a handbook by South 

 American students. With these points in view, a short ge- 

 neral account of the group, and generic keys, have been 

 preseuted. 



Many of the newforms described have been forward- 

 ed to the Burean bv Piof. Carlos E. Porter, whose Ínter-
