The bulletin is a summary of the known habits of these species, with 
indications of the best methods of treatment, the article on the Vine 
Leaf-hopper being perhaps the most important. 
Corrections to Packard’s Report on Forest Tree Insects.— We call atten- 
tion to a valuable article, in another part of this number, by Dr. John 
Hamilton, regarding certain corrections and additions to Dr. Packard’s 
report on forest insects. 
The changes which Dr. Hamilton proposes in the nomenclature of 
various species of Coleoptera are justified by the law of priority, and 
nearly all of his other corrections and suggestions are fully justified. 
Similar synonymical or critical notes could be made in nearly all the 
other orders of insects, and no one will be more thankful to receive 
them than Dr. Packard himself, as he has particularly requested such 
corrections and additions, and is fully aware of the imperfections of the 
report in this respect. It is further due to ourselves to state in this 
connection that while aiding Dr. Packard so far as time would permit 
in the getting out of the report, it was utterly impossible and would 
have been entirely inappropriate to include all the facts and informa- 
tion at our command, and that for want of time the unpublished notes 
which were furnished to Dr. Packard were limited to certain trees and 
were neither revised nor amplified. In connection with Dr. Hamilton’s 
coleopterological comments it may be well to add a few further facts 
and suggestions, referring, as he has done, to the pages of Packard’s 
report which evoke them. 
In cases where economic articles are quoted from the older American 
authors, the names employed by said authors should, in our judgment, 
be used in note or brackets, where they are superseded by some prior 
name. If, for instance, Hylurgops glabratus Zett. is used to supersede 
the name of Hylastes pinifex Fitch, without reference to the latter’s 
name, it would be difficult for anyone not especially familiar with the 
synonymy of Coleoptera to refer, for the sake of identification, to Fitch’s 
original article. : 
In reference to the misapplication of popular names which Dr. Ham- 
— ilton calls attention to, in the case of Magdalis olyra Hb., the same may 
be said of a large number of other names. When the names are based 
on the food-habit, they have become misnomers chiefly through subse- 
quent experience and investigation having multiplied the food-plants. 
A striking case in point is that of the Clover Stem-borer (Languria 
mozardi), which is now known to bore in the stems of a number of com- 
mon weeds.
