Elm Insects.—Prof. G. H. Perkins has recently distributed a 96- 
page memoir, extracted from the Eleventh Report of the Vermont 
State Board of Agriculture, upon Insects Injurious to the American 
Elm. Eighteen introductory pages are devoted to a consideration of 
predaceous and parasitic insects, insectivorous birds and other ani- 
mals, and the use of insectides. Then follows a short discussion of 
the usefulness of the American elm, and the reasons for treating of the 
insects affecting it, after which appears a systematic list of seventy- 
eight insects injurious to the elm. A more or less complete account is 
then given of each of these species, the writings and illustrations of 
previous authors being freely used, with full credit. Unfortunately 
the otherwise excellent mechanical execution of the drochure is seriously 
marred by the occurrence of numerous typographical errors. In 
several places also slips occur, due, apparently, to a lack of the latest 
information. For instance, in discussing kerosene emulsion, ‘ Prof. 
Riley's recipe ”’ is said to be ** a mixture of oil and milk of any de- 
sired proportions," and no mention is made of the Riley-Hubbard 
soap emulsion, which is now the accepted formula everywhere. And 
under the head of beetles infesting elms a list of species mentioned 
by Glover and Harris is given, the names of many of which have 
since been changed, and some of which are synonyms. The genera 
Phyllophaga and Trichestes are not now recognized in the lists of 
American Coleoptera, The imported coccid ( Gossypari ulmi) is called 
the imported elm leaf aphis. This is unfortunate, as the term aphis 
should at least be restricted to insects of the family Aphididae. But
