APPENDIX IV. 
BIBLIOGRAPHY OF SOME OF THE LITERATURE CONCERN- 
ING DESTRUCTIVE LOCUSTS. 
By B: Pickman Mann. 
Since I received a request to prepare an account of the various books and articles 
treating of destructive locusts on this continent and the continents of Europe, Asia, 
and Africa, circumstances have prevented me from devoting to the task enough time 
to do it any manner of justice. If I offer this very imperfect sketch it is only because 
I am warned that -whatever is to be used must be furnished soon. 
It will be noticed that I have made especial use of two books containing biblio- 
graphical material: the Bibliotheca Entomologica of Dr. H. A. Hagen (1862) aud the 
article Ueber die Heuschrecken in Siidrussland of F. Tkdr. Koppen fil. (1865) ; also, that 
I have taken some citations from Gerstacker's pamphlet, Die Wanderkeuschrecke 
(1876). I have designated my extracts from these works by citing the names of the 
authors. 
References to works upon a subject like the present may be classed as general and 
particular. Under the latter division I would place the citation of passages concern- 
ing destructive locusts in books of travel or other works not treating generally of the 
locusts. The number of such citations here given is small, and it is so mainly because 
most of the citations which I could make were already included in a few general 
works upon destructive locusts, viz., in the works by Ludolf (1694), Eiselt (1836), 
Keferstein (1843), and Koppen (1865), and, to a great extent, all the information con- 
tained in the passages so cited is transferred to the pages of one or more of the four 
works last mentioned. As far as I could, I have given a complete list of the works 
which have for their general subject the consideration of destructive locusts. I am 
far from having exhausted the subject, however, especially for works later than the 
Bibliotheca Entomologica, and I would point out, as an especially fertile field of re- 
search for any one who may wish to supplement my list, the annual reports upon 
entomology made by Bnrmeister (1834-1835), Erichson (1836-1848), Schaum (1848- 
1852), Gerstiieker (1853-1866), Brauer (1867-1870), and Bertkau (1871-1874;, in the 
Archiv fur Naturgesckichtc, edited bv Wiegmann (v. 1-6, 1835-1840), Erichson (v. 
7-14, 1841-1848), and Troschel (v. 15^4, 1849-1878) ; also, the Record of Zoological 
Literature and Zoological Record for 1864-1873 (10 v., 1865-1875), and the Cata- 
logue of Scientiiic Papers for 1800-1863 (6 v., 1867-1872), by the Royal Society of 
London. 
For recent and future North American entomological literature, see the Biblio- 
graphical Record published in Psyche, the organ of the Cambridge Entomological 
Club, v. 1 (1874-1877), v. 2 (1877-1879), and subsequent volumes. 
Titles which I have compared with the originals are designated by an asterisk (*) 
placed before them ; titles thus verified by Dr. Hagen are preceded by a dagger (t).
