144 Girault, Bibliography of the Bedbug, Cimex lectularius Linnaeus. 



The bibliography is complete up to the year 1906. It com- 

 prises nearly six hundred titles, nearly all of^which have been 

 verified, entailing much painstaking effort. Those titles which have 

 been inaccessible are marked with an asterisk. Those which are 

 considered important, authoritative or contributive, have the date 

 preceding them in italics. 



The titles are grouped into more or less arbitrary divisions and 

 subdivisions, according to their subject-matter. These are as follows: 

 I. Entomology: a) systematic ; b) biologic and economic; c) ana- 

 tomical; d) prophylactic and remedial. II. Medicine: a) derma- 

 tological; b) pathogenic; c) therapeutic. III. Zoological: or general, 

 containing miscellaneous compilations. 



Under these groups, the titles are arranged chronologically or 

 historically, and then alphabetically. As a rule, each reads as fol- 

 lows: Date of publication; author; title of article; citation of journal, 

 periodical, or tome ; place of publication ; citation of edition, volume, 

 page and figure; reprints, reviews, other editions and so on. The 

 author's name is always given in full if known. If the author of 

 an anonymous paper is known, his name is given, followed by Anon, 

 or his initials in parenthesis, according to circumstances; if not known 

 with certainty, the Anon, is given first followed by the name in 

 parenthesis. The title of articles are usually given in full, if not 

 too long, and always exactly as they were published, excepting capi- 

 talization. When too long, enough of the title is given to insure 

 identity, followed by the letters etc. as here written. Scientific 

 names in titles are not italicized unless so found in the original. 

 In citing the publication, its full title is also given, if possible, 

 generally without abbreviation ; the abbreviations used are standard 

 and readily understood. The author is not responsible for those 

 titles marked with an asterisk. A title is considered complete after 

 citation of volume, pagination, and illustration. The date of publi- 

 cation, place of publication, pagination, and so forth, are not repeated 

 in citing reprints, "separates", other editions, and so on, unless diffe- 

 rent from those given in the original title. Other arrangements are 

 those now generally followed in bibliographies, and therefore require 

 no specific explanation.

 ledging his indebitness to the following, who have aided him in
