part of the large volume is clear and simple and most interesting 

 to every Nature Student. . . . No one can take up the book and 

 open it anywhere without becoming deeply interested in the sub- 

 ject treated of, whatever it may be, provided, that is, that he has 

 any love at all for living creatures, any interest in the myriad 

 forms and modes of life of these wonderful beings that are 

 everywhere about us." Canadian Entomologist. 



" Sumptuous, delicate, exquisite, these are the words that easily 

 leap to our lips in looking through the book. But I cannot too 

 much emphasize the fact that in the volume we also have science 

 made thoroughly readable." E. P. Powell in Unity. 



"Is probably the most valuable handbook of the subject for 

 the technical student or amateur collector." Kansas banner. 



"Ein ebenso reichhaltiges wie luxuries ausgestattetes Werk 

 zur Einfiihrung in das Studium der Biologie der amerikanischen 

 Insekten." Edin. Reitter in Wiener Ent. Zeitung. 



" The book is of the first importance in its class." Out West. 



"This work easily ranks as the most comprehensive volume 

 treating of American insects yet produced. . . . The subject- 

 matter is presented in an easy narrative style, though accuracy 

 is not sacrificed for the sake of popularity. . . . The volume ex- 

 hibits a thorough appreciation of and familiarity with recent in- 

 vestigations. . . . This work brings together in one volume a 

 vast amount of information and the author is to be congratulated 

 upon having produced a very readable, comprehensive work, 

 which should prove attractive and exceedingly helpful to the 

 amateur as well as essential to every investigator." .ZT. P. Pelt 

 in Psyche. 



" We have in this single volume a whole library of insect lore." 

 N. Y. Critic. 



" Es ist ein gewaltiges Unternehmen, das Verf. in diesem 

 Werke zur Durchfuhrung gebracht hat und die vollendete Art 

 und \Veise dieser Durchfuhrung diirfte dem Buche in seinem 

 Vaterlande einen vollen Erfolg sichern. Es will seinen Lesern 

 eine Uebersicht iiber die gesammte Insektenwelt geben,aber nicht 

 in dem oberfiachlichen Feuilletonstil, den man in derartigen 

 \Verken haufig findet, sondern mit wirklichen wissenschaft- 

 licher Griindlichkeit, und das ist dem Verfasser vorzuglich 

 gelungen." Zeitschr.Ji'ir wissenicliaftliche Insektenbiologie. 



" The work is probably the best that exists for anyone desiring 

 an introductory work on North American insects compressed 

 into a single volume." David Sharp in Aature. 



" We are glad to see the interesting chapter on insects and dis- 

 ease, as it places the subject on a higher plane with the general 

 public, and is a matter of immense importance to humanity. 

 Taking the work in its entirety it is a valuable contribution to 

 the subject, and can't fail to be useful to the student beginner 

 as well as to entomologists in general." Entomological J\ ezvs. 



"To many readers, especially to those who, whilst studying 

 specially one order, want a clear explanation of the general 

 character and biology of the other orders, the book must be a 

 precious boon, from which the fact that the illustrations are 

 taken from American insects detracts nothing. Dr. Kellogg has 

 long undoubtedly been in the first rank of American entomolo- 

 gists, and this latest \vork can only add lustre to an already 

 distinguished name."-^/. W. 7*utt in Entomologist's Record 

 (London).
