﻿IV PREFACE. 



sent out till into the Fall. P^roni a small, separate-bound edition, which I always have 

 published and sent out at my own expense, it was noticed, and extracts were made 

 from it, both at home and abroad soon after its completion ; but the fact nevertheless 

 remains that it was not distributed among our farmers till long after many of them had 

 applied for it ; and the only way to avoid such difficulties in the future is to have the 

 two reports separately bound. 



As it is frequently advisable to give to the publ'c facts to be embodied in these 

 Reports when they are yet fresh and most useful, I liave cliosen as media for so doing 

 the New York Weekly Tribune and Colmans Rural ]Vorl(l more particulai'ly, so that 

 some of the matter in the present lleport has already appeared, generally over my own 

 name or initials, in the columns of those journals. 



In this, as in the previous volumes, when the insects treated of are new, or the 

 existing descriptions of them arc imperfect, or in a foreign language, or in works out 

 of print or difficult of access, I have added a full description, which is, however, always 

 printed in smaller type, so that it can be skipped by the non-interested reader. I 

 have endeavored to give a popular name to each insect of economic importance, and 

 this is invariably accompanied, wherever accuracy demands it, by the scientific 

 name, and the latter is generally printed in italics and mostly in parenthesis, so that it 

 may be skipped by the practical man without interfering with the text. The Order 

 and Family to which each insect belongs, are also given under each heading. The 

 dimensions are expressed in inches and the fractional parts of an inch. Where so 

 small, however, as to render such measurement inaccurate, I have adopted the mili- 

 meter— one milimeter (1 mm.j not quite equaling twenty-five hundreths of an inch 

 (0.25 inch.) The sign (^' wherever used, is an abbreviation for the word "male," the 

 sign $ for "female," and the sign " for neuter. 



Some of the figures are enlarged, but the natural size of each of such is also given 

 or indicated by a hair-line, except in the representation of enlarged stuctural details, 

 where they are connected with the life-sized insect to which they belong. 



The name of the author of the species, and not of the genus, is given as authority ; 

 and in order to indicate whether or not the insect was originally described under the 

 generic name which it bears, I have adopted the following plan : When the specific 

 name is coupled with the generic name under which it was first published, the de- 

 scriber's name is attaclied without a comma — thus indicating the authorship of the 

 dual name : e. g. Phycita nebulo Walsh. But when a difterent generic name is em- 

 ployed than that under which the insect was first described, the authorship is enclosed 

 in parenthesis thus — Acrobasis 'nebulo (Walsh ;) except where the whole name is already 

 in parenthesis, when a comma will be used for the same purpose ; e. g. (Acrobasis 

 nebulo, '^\'alsh.) 



All the illustrations, unless otlierwise stated, are drawn by myself from nature. 



My office is still at Koom 42, St. Louis Insurance Building, N. \V. Corner of Sixth 

 and Locust Sts , where all communications should be sent. I tender nij' cordial 

 thanks to the officers of the Iron Mountain, K. C. & Northern, and Mo. Pacific Kailroads, 

 for courtesies extended, in the way of passes, over their respective lines.
