THE FOSSIL INSECTS OF NORTH AMERICA. 



WITH NOTES ON SOME EUROPEAN SPECIES. 



By DE. SAMUEL H. SCUDDER, 



Paleontologist of the U. S. Geological Survey, in charge of the Division of Fossil Insects. 



With sixty-three Plates and numerous Illustrations in the text. Two volumes, 4to, $20.00. 



Contents: Vol. I.— The Pretertiary Insects (with 35 plates). Vol. II.— The Tertiary Insects (with 28 

 Plates). 



These two volumes, of which only one hundred copies are issued, form the most extensive work on 

 Fossil Insects that has ever been published. Over eight hundred and fifty species are described, and 

 most of them are figured on the lithographic plates. 



The descriptions include, with two or three exceptions, all the Fossil Insects which have ever been 

 described from North America, besides a very large number nowfirst published, and especially among the 

 paleozoic and mesozoic cockroaches a considerable number of European forms. But besides the merely 

 descriptive matter, the general student will find scattered through both volumes essays on the classifi- 

 cation, distribution, and geological sequence of the different groups. The term insects has been used in 

 a broad sense, to include myriapods and arachnids, as well as hexapods, or true insects.

 "The first of these two palseontological works is 

 Nicholson and Lydekker's 'Manual of PalEeontology/ 

 in which, for the first time, I believe, in the English 

 language, a fairly comprehensive account of the 

 animal kingdonu, as represented in past times, has 

 been afforded to students." — Address by W. T. 

 Blanford, Esq., LL.D., F.R.S., Fresidenf of the Ge- 

 ological Society of London. 



"The work furnishes the student with an excel- 

 lent summary of the leading principles of palseonto- 

 logical science— by far the most complete which has 

 ever been published in the English language."— 

 Geological Magazine {London). 



"The book is the best test-book on the subject in 

 the language. . . . Nothing better than the in- 

 troduction to the study of the science has come 

 under our notice."— il/erf/ca/ Press {London). 



"It has been well and conscientiously done. . . 



. A manual which no geologist who wishes to 



know what has been done of late in the palaeonto- 



logical field can afford to do without." — Journal of 



Education (London^.
