INTRODUCTION. $ Few groups of insects have been more neglected by entomologists and collectors than the Aleyrodida?. It is believed that comparatively few of all the species which undoubtedly exist have as yet found their way into collections. The family is widely distributed in the temperate and tropical regions of the world, and it will perhaps, when thoroughly worked, prove to be about as rich in species as the Coccidae or Aphididse. Beginning with Maskell's paper, which appeared in 1895, there have followed a number of publications dealing with the Aleyrodidge, most of them systematic in character, but some dealing with the biology and habits of certain species of considerable economic importance. These papers have come from widely separated parts of the world, as New Zealand, the United States, India, Europe, Japan, etc., and indicate an increasing and widespread interest in these insects. Until 1907 only two genera for the family were recognized, Aleyrodes and Aleurodicus. Since this date, however, three additional genera have been established, namely, Aleurochiton, Paraleyrodes, and Udamoselis, the discovery of which has thrown much light on the probable position of the Aleyrodidse in relation to other families of insects, and on the lines of descent of the several subgroups within the family itself. The insect collections of the United States National Museum and of the Bureau of Entomology contain a large amount of material of this family received from correspondents from many parts of the country, and have been recently considerably augmented by the large series of specimens attained by Mr. E. S. Woglum, of the Bureau of Entomology, in connection with his search for natural enemies of the citrus white fly {Aleyrodes citri R. & H.) in the Orient. The bureau also has, as stated in an earlier publication, through the kindness of the New Zealand Institute, the temporary custody of the Maskell collection of Aleyrodidse, including nearly all of his types. It has therefore seemed appropriate to undertake, at this time, a revision of the group as a whole, and to determine as 1 2 CLASSIFICATION OF THE ALEYRODIOE. accurately as possible a system of classification based upon the natural relationship of the various forms. when the forms have been carefully studied. In Paraleyrodes segments III to VII have become united so as to form two.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
