Tribe PHYTOPHAGA. 



(Supplement to Vol. VI. Paet 1.) 



Since the publication of this portion of the Phytophaga was commenced in June 

 1880 a great number of accessions have been added to the collections placed at my 

 disposal for examination. These relate chiefly to the earlier groups, those referable to 

 the later ones having been duly inserted in their places. The additions therefore in 

 all the Families from the commencement to the Eumolpidse are very numerous and 

 will render this part of the Supplement much more extended than that relating to the 

 large Families which follow. The collection of M. Salle had not then been acquired ; 

 and Mr. Champion had only been working for a short time in Guatemala, and his 

 explorations in the State of Panama had not been commenced. Most of the additions 

 derived from Herr Hoge's second Mexican expedition have also still to be dealt with. 

 These and many smaller consignments received from time to time have all swelled the 

 materials which I now propose to examine.

The twelve or thirteen species placed in this genus chiefly inhabit Europe or North 

 America ; three, however, are known from Chili and one from Ceylon. One of the 

 North- American species extends southwards to our northern boundary.
