SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION

The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Institution, Joseph Henry articulated a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge not stricdy professional.” This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series:

Smithsonian Annals of Flight

Smithsonian Contributions to Anthropology

Smithsonian Contributions to Astrophysics

Smithsonian Contributions to Botany

Smithsonian Contributions to the Earth Sciences

Smithsonian Contributions to Paleobiology

Smithsonian Contributions to Zoology

Smithsonian Studies in History and Technology

In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. Each publication is distributed by mailing lists to libraries, laboratories, institutes, and interested specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

A Checklist of the American Bidessini (Coleoptera: Dytiscidae-Hydroporinae)

Frank N. Young

____________

Frank N. Young, Department of Zoology, Indiana University, Bloomington, Indiana 47401.

This checklist attempts to bring together all of the names of water beetles of the family Dytiscidae, sub-family Hydroporinae, tribe Bidessini, which have been proposed for species from the Americas and to assign them as far as possible to currently accepted genera. In large part, reliance has been placed upon the original descriptions of the species, but wherever possible specimens have been examined. The latter include material in the British Museum (Natural History), United States National Museum, California Academy of Science, Museum of Comparative Zoology, University of Michigan Museum of Zoology, American Museum of Natural History, Zoologische Sammlung des Bayerischen Staates (Munich), and the collection of the writer.

An asterisk (*) preceding a species name indicates that I have personally examined the type or authentic cotype or paratype material and confirmed the generic assignment or synonymy. Those preceded by a question mark (?) are tentatively assigned pending further study. Those names considered to be synonyms, some of which probably represent geographical subspecies, are indicated by an “s-” preceding the name.

The arrangement adopted is that of the Leng Catalogue (Leng, 1920; Leng and Mutchler, 1927, 1933; Blackwelder, 1939) and Blackwelder's Checklist of Coleopterous Insects of Mexico, Central America, the West Indies, and South America (1944–1957). The citations to the literature are in the abbreviated form of these works and refer to the bibliographies in them with the exception of those followed by an exclamation mark (!), which are cited in full at the end of the present paper.

The references have been cross checked with the Coleopterorum Catalogus (Zimmermann, 1920), Zoological Record, and the original books or papers.

The shortcomings of such a list as this are evident, but some arrangement of the American species is necessary to provide a basis for further investigation. There are dozens, possibly hundreds of Bidessines awaiting study, particularly from Mexico and South America. This work has been seriously hampered by premature publication of incomplete descriptions. The male genitalia prove to be especially valuable in the diagnosis of species in many of the genera, and I urge that all future descriptions of new species be accompanied by figures of these structures.

Platydessus perforatus Guignot (55–4), described as a Bidessine, is not included because it was found to be a Macrovatellus (Vatellini) and was transferred to that genus by Spangler (66–57).

Publication in Smithsonian Contributions to Zoology

Manuscripts for serial publications are accepted by the Smithsonian Institution Press, subject to substantive review, only through departments of the various Smithsonian museums. Non-Smithsonian authors should address inquiries to the appropriate department. If submission is invited, the following format requirements of the Press will govern the preparation of copy. (An instruction sheet for the preparation of illustrations is available from the Press on request.)

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with 1½″ top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number consecutively all pages, including title page, abstract, text, literature cited, legends, and tables. The minimum length is 30 pages of typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Taxonomic titles will carry a final line indicating the higher categories to which the taxon is referable: “(Hymenoptera: Sphecidae).” Include an abstract as an introductory part of the text. Identify the author on the first page of text with an unnumbered footnote that includes his professional mailing address. A table of contents is optional. An index, if required, may be supplied by the author when he returns page proof.

Two headings are used: (1) text heads (boldface in print) for major sections and chapters and (2) paragraph sideheads (caps and small caps in print) for subdivisions. Further headings may be worked out with the editor.

In taxonomic keys, number only the first item of each couplet; if there is only one couplet, omit the number. For easy reference, number also the taxa and their corresponding headings throughout the text; do not incorporate page references in the key.

In synonymy, use the short form (taxon, author, date, page) with a full reference at the end of the paper under “Literature Cited.” Begin each taxon at the left margin with subsequent lines indented about three spaces. Within a taxon, use a period-dash (.—) to separate each reference. Enclose with square brackets any annotation in or at the end of the taxon. For references within the text, use the author-date system: “(Jones, 1910)” or “Jones (1910).” If the reference is expanded, abbreviate the data: “Jones (1910, p. 122, pl. 20: fig. 1).”

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy.

For measurements and weights, use the metric system instead of (or in addition to) the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed throughout the printed text. They will be termed Figures and should be numbered consecutively; however, if a group of figures is treated as a single figure, the individual components should be indicated by lowercase italic letters on the illustration, in the legend, and in text references: “Figure 9b.” If illustrations (usually tone photographs) are printed separately from the text as full pages on a different stock of paper, they will be termed Plates, and individual components should be lettered (Plate 9b) but may be numbered (Plate 9: figure 2). Never combine the numbering system of text illustrations with that of plate illustrations. Submit all legends on pages separate from the text and not attached to the artwork.

In the bibliography (usually called “Literature Cited”), spell out book, journal, and article titles, using initial caps with all words except minor terms such as “and, of, the.” (For capitalization of titles in foreign languages, follow the national practice of each language.) Underscore (for italics) book and journal titles. Use the colon-parentheses system for volume, number, and page citations: “10(2):5–9.” Spell out such words as “figures” and “plates” (or “pages” when used alone).

For free copies of his own paper, a Smithsonian author should indicate his requirements on “Form 36” (submitted to the Press with the manuscript). A non-Smithsonian author will receive 50 free copies; order forms for quantities above this amount with instructions for payment will be supplied when page proof is forwarded.
