 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

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 syuonymical 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 fiicts 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 tion at our command, and that for want of time the unpublished notes 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 sui)erseded by some prior 

 name. If, for instance, Hylurgop.s ghibratus Zett. is used to supersede 

 the name of Hylastes lymlfex 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 MagdaUs olyra Hb., the same may 

 be said of a large inimber 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.
