In the following works the running titles are abbreviated forms of the 

 names of the works, or at least give no more specific idea of the contents 

 of the pages under them :

 Smith's Catalogue of Noctuidae ; Smith's Insects of New Jersey ; Hen- 

 shaw's List of North American Coleoptera ; Wiilistcn's North American

I am well aware that this may seem a very unimportant matter to the 

 author of a catalogue or list, and also that in most cases the authors 

 probably have nothing to say about it, but the printing is done according 

 to the rules adopted by the institution or official department issuing the 

 publications. Nevertheless, where one has occasion to look up several 

 hundred references in a day, he finds these little matters of considerable 

 value as guides. Without them he must depend largely upon the in- 

 dex.— W. E. Britton.

North American Phvlloxerin^ affecting Hicokia (Carva) and 

 OTHER Trees. By Theodore Pergande. Reprinted from Vol.

 port, Iowa. 

 A contribution to these little-known insects of 89 pages, 21 plates. All 

 the old species of these plant lice have been studied and twenty new 

 species and varieties made known. An interesting account of the life 

 history of one of the new species, P. perniciosa, is given, and is charac-

 value to have such an excellent treatise on these obscure and little studied 

 insects. The author says: "since the species treated of in this paper

 still a large field for fruitful investigation which may amply occupy the life- 

 time of those selecting it as a specialty."— H. Skinner.
