 species of Lecauinin, to which I have access, none agree so well 

 with the present species as does Dr. Fitch's description of his 

 L. caryee ; but Prof. Riley has compared specimens and finds 

 rarVd? to be much larger."

Notes on Aleurodidae. 

 By H. O. Woodworth, Champaign, 111. 



The appearance last July of Bulletin No. 8, Technical Series, 

 Div. of Ent., U. S. Dept. of Agric, by Prof. A, L,. Quaintance, 

 entitled : ' ' Contributions Toward a Monograph of the Ameri- 

 can Aleurodidae," brought to the writer's attention this nuich 

 neglected family. 



In Illinois there were reported by that paper only three spe- 

 -cies upon as many hosts. Therefore the writer decided to use 

 his spare time in the study of the local species and such others 

 as he might collect elsewhere. As a result, in the last few 

 months, .specimens from about one hundred kinds of plants 

 were collected, of which at least three-fifths are new to the 

 monographic list. From some species of plants as many as five 

 kinds of Aleurodids were found.
