Original copies in printed paper covers are filmed beginning with the front cover and ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression.

Les exemplaires originaux dont la couverture en papier est imprim6e sont filmis en commenpant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'illustration, soit par le second plat, salon le cas. Tous les autres exemplaires originaux sont ffiim^s en commen^ant par la premidre page qui comporte une empreinte d'impression ou d'illustration et en terminant par la dernidre page qui comporte une telle empreinte. The last recorded frame on each microfiche shall contain the symbol —^> (meaning "CON- TINUED"), or the symbol y (meaning "END"), whichever applies. Un des symboles suivants apparaitra sur la dernidre image de cheque microfiche, selon le cas: le symbols —► signifie "A SUIVRE", le symbole y signiffie "FIN".

Deak Siu: Duriiii,' my coiUK^ctioii, for tin; i)iist four years, willi llic (ico- logiral Survey of (lie Territories eoiitliicted under your eliiirire, I imve l.rcii enabled to eolleet a large; nnniUer of speeiineus of Ortlioplera, espi.-eially of Aerididie; and having made the study of liiis family a specialty for several years past. I conceived the idea of prepa.-ing a niono<.'rapli or synopsis of the species tliereof found in the United States. Having mentioned this idea to you, I am hajipy to say that you iieartily approved of it, and yave me all llu! (!i)C()uragemen1 and aid therein consistent with the oilier and more practical duties of the Survev. i*>y this encouragemeni and aid, and the use of the name of the Survey, I have succeeded in collecting loiretlwr a larire nuinher of specimens, representinif not only almost all the previously-described spe- cies, l)ut also a mnnher of new ones, most of which have been described and reported, from time to time, il)r publication in yohr annual reports: a ii-w are herein iioticeil for the first time. I herewith pn'sent the result of my labors in this direction, trusting that it may prove accei)tal)le, and that it may con- tribute something, be it ever so small, to the advancement of scientilic knowl- edife. It is possible that a delay oi' aiutther year would have enal)led me to render it more complete and satistiu'tory ; l)ut I have concluded it is liest to bring it itefore the pnl)lic as soon as possii)le, as it will be one aid to ento- mologists in determininu; new species, and thus enal)Ie them the sooner to complete the list of the species of this important family which belouir to the North American iiiuna. I have entitled it a "Synopsis,'' instead oi" •'Moiio- lirapii," because I have not had an opportunity of inspectinii all the described species, nor of examining numy of the original types of other authors. In order to render it as complete and as usefid as possible, 1 have added descriptions of the species tbund in other parts of North Anu-rica, but which do not Ix'long to the United States liuma. Thesi; descri[)lions are chielly from the authors l)y wlunn they were originally described, as I have had an opportunity of inspecting but few of the species, ami very few of them have been figured. 2 Tlit^ types of all i\\r new specifs wliicti I iuiv.- (Icscrilx'.l have been placed in the A-i'iciiltiinil Drpiirtiii.'iit, where they will l)e pivsorvr.l, tiius iilK.nlinir a rea.ly means of reuTeiiee in liituir investiirations. (,)uite a nuiul.er of th.'s(^ hiive been tiixmvd by i'n.lessor Townend OIov.t. and will be roun.l in his "Illustrations of Xerti. American Entomology— Oithoi.teni," published in '.,;iarto durlnfrthe past season. An exauiinatioi. of this synopsis will show that about one hundivd and twenty species of I iiis-linnily, exclusive of the 'r.'tli-in;e. aiv .lescriiu'd as bclonirini; to the United States, and as ivpreseutini: twenty-live genera.
