120 THE CANADIAN ENTOMOLOGIST. 



enemies — the beneficial insects. The species are profusely illustrated with 

 excellent, often superior wood cuts ; the well-known cuts of Mr. C. V. 

 Riley are largely represented, and rather dangerous for all others. 



The plain and judicious manner in which remedies are recommended 

 is a decided and prominent feature of the book. There are no ambiguous, 

 no large-mouthed sentences, no humbug about millions lost by such an 

 enemy, or millions saved by such a remedy. There is nothing but plain 

 truth, said in the most unpretentious words. I think every scientific 

 student is deeply obliged to the author for his happy innovation. 



Of course the author has, besides his own large experience, used all 

 the rich and splendid discoveries and observations published by other 

 scientists. The absence of quotation marks is entirely justified, as they belong 

 to the history of the natural history, but not to a practical book intended 

 for fruit-growers. Scientific students know where such facts are published, 

 and the author has in the preface fully satisfied all economic entomolo- 

 gists with his acknowledgments. It is obvious that in a book treating of 

 the history of so many species, omissions and sometimes errors cannot be 

 entirely avoided. Since the book is issued and the errors are insignificant, 

 we may safely leave them to be corrected by the author himself. £eHe

IMPORTANT TO ENTOMOLOGISTS. 



In accordance with a resolution passed at a meeting of the Entomolo- 

 gists in attendance at the Montreal Meeting of the American Association 

 for the Advancement of Science, in August, 1882, authorizing me to call 

 and ''to provide for similar meetings for Entomological discussions at the 

 future annual gatherings of the Association," I herewith name A\'ednesday, 

 August 15th, 3 o'clock p. m., as the time for the first of the series of the 

 MinneapoUs (Minn.) meetings, the place of meeting to be named hereafter. 



All interested in Entomology are respectfully invited to attend the 

 meetings, and participate in the discussions. J. A. Lintner.

I have gathered, since the leaves fell, twenty-one cocoons of A. /una, 

 and each one bears evidence that it was spun after the larva left the tree 

 on which it fed. Warner W. Gilbert, Rochester, N. Y.
