(SUPPLEMENT To Vou. VI. Parr 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 Eumolpide 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. Sallé 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 Hége’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.
