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.” 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. These publications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

Introduction

Another 174 types of Dognin, Druce, Dyar, Henry Edwards, Schaus, and Strand species are reviewed in this second and final volume on the Neotropic Arctiinae types in the National Museum of Natural History (USNM collections).[*] Many of these types had not been illustrated previously, and the genitalia of only three types had been dissected. A total of 619 has now been examined–slightly fewer than estimated in Part I (Watson, 1971).

As in Part I, I have designated lectotypes for those species whose original descriptions were based on a syntypic series. Lectotypes have also been designated for those species not described specifically from a single specimen but where the original description gives no indication as to the size of the syntypic series, if one existed (e.g., see Hypomolis amabilis Schaus). The designated lectotypes are invariably those which have born the red USNM type-number label for many years. Acceptable lectotype designations have been made already for two species, Hemihyalea euornithia and Hemihyalea nimbipicta, described by Dyar (1914a). Their author makes a definite statement about the “Type” specimen of each species and gives details of the pin-label data (Dyar, 1916).

The revision of Automolis (sensu auctorum), referred to in Part I, has not yet reached a stage at which the list of species mentioned there can be presented.

There has been some confusion in the literature concerning the spelling and date of publication of Phaegoptera Herrich-Schäffer [1853]: see, for example, Travassos (1948, pp. 493–497). The dates of publication of both the text and the plates of Herrich-Schäffer’s Sammlung neuer oder wenig bekannter aussereuropäischer Schmetterlinge have, in fact, been listed in the Catalogue of the Library of the British Museum (Natural History) (Vol. 6, Supplement A–I, 1922, p. 458), while the publication dates of the plates have been discussed by Dalla Torre (1927, pp. 1–2).

The wrappers, which enclosed the plates on publication, contained a list of the figured genera and species, together with locality and collector data. These were released, in most instances, before any other associated text. For example, the original description of Phaegoptera [1853] preceded by three years the publication by Herrich-Schäffer of additional text ([1856], p. 16, and [1858], p. 78). The original spelling, Phaegoptera (as it appeared on the wrappers), was used again later in the same work ([1858], p. 78) and cannot therefore be considered a lapsus calami or a copyist’s or printer’s error (see Article 32 (a) (ii) of the Code). The spelling “Phegoptera,” used by Herrich-Schäffer, on p. 16 [1856] and wrongly attributed by him to Boisduval, must be regarded as an incorrect subsequent spelling.

To summarize the above, the correct citation should read: Phaegoptera Herrich-Schäffer [1853], Sammlung neuer oder wenig bekannter Schmetterlinge 1, legend to plates 14, 15, figures 58–68 (wrappers). The type-species of Phaegoptera is Phaegoptera histrionica Herrich-Schäffer [1853], ibidem, 1, legend to plate 15, figure 68 (wrapper), by subsequent designation by Kirby (1892, p. 212).

Phoegoptera Boisduval (1869, p. 81), erected for three new species, should be mentioned here. There is insufficient evidence to state with certainty whether it was Boisduval’s intention to propose Phoegoptera as a new generic name, but this interpretation seems more reasonable than the assumption that Phoegoptera was an intended, though misspelled, reference to Phaegoptera Herrich-Schäffer: Boisduval makes no reference to Herrich-Schäffer or to any of those species originally included in Phaegoptera. I have been able to find only one reference to a type-species for Phoegoptera–by Hampson (1920, p. 268): “Phoegoptera [sic], Boisd. Lép. Guat. p. 99 (1870), non descr.…Type. alterata.” The name alterata is presumably a misspelling of alternata Grote, a species not originally included in the genus, but added to Phoegoptera by Boisduval in his paper on the Lepidoptera of Guatemala a year after the description of the genus. In the absence of a valid type designation, it is necessary to choose one of the three originally included species: P. cinnamomea Boisduval, currently considered a junior subjective synonym of Aemilia roseata (Walker); P. quercus Boisduval, a junior subjective synonym of Hemihyalea edwardsi (Packard); and P. salicis Boisduval, a junior subjective synonym of Halisidota maculata (Harris). The choice of either P. cinnamomea or P. quercus would result in the relegation to synonymy of either Aemilia Kirby, 1892, or Hemihyalea Hampson, 1901, and the establishment of Phoegoptera Boisduval as the valid name for those species at present placed in Aemilia or in Hemihyalea. This is as undesirable as the resultant existence of two valid generic names in the Arctiinae differing by only one letter. By designating the remaining species, P. salicis Boisduval, as the type-species, the name Phoegoptera can be placed in the synonymy of Halisidota Hübner [1819]. Furthermore, Phoegoptera would still remain in synonymy if it were found necessary to remove Lophocampa Harris, 1841, from the synonymy of Halisidota, together with its type-species, H. maculata (=salicis), a close ally of L. caryae Harris, which is the type-species of Lophocampa.

In summary: The correct citation is Phoegoptera Boisduval, 1869, Annales de la Société Entomologique de Belgique, 12, p. 80. The type-species, by present designation, is Phoegoptera salicis Boisduval, 1869, ibidem, 12, p. 81. Phoegoptera now becomes a junior synonym of Halisidota Hübner (new synonymy).

A further nomenclatural change results from McDunnough’s (1938, p. 52) transference of Seirarctia clio Packard (1864, p. 120), the type-species of Euverna Neumögen and Dyar (1893, p. 141), to Ectypia Clemens (1860, p. 529), which automatically relegated Euverna to the synonymy of Ectypia. The species name mexicana Dognin, previously combined with Euverna, is therefore newly combined with Ectypia in this paper (new combination).

ARRANGEMENT AND CONTENT OF CATALOG ENTRIES.—The procedure followed in Part I of this catalog (see Watson, 1971, pp. 2–3) has been adhered to in this volume. Catalog entries are alphabetic with reference to those nominal species-group taxa whose types are dealt with. The currently valid binomen heads most catalog entries, but it is placed in square brackets beneath those names that at present are considered to be junior synonyms (e.g., Antarctia bergi Schaus [junior synonym of A. costata Burmeister]). Color-terms are those used by Kornerup and Wanscher (1967). A quotation from the original description has been given if an abdomen was too badly worn or stained to enable a description of its color to be made or if it had been dissected prior to the present study. The selection and labeling of lectotypes follows the practice adopted in Part I: a statement “Lectotype…By A. Watson…” in the third paragraph of a catalog entry is a lectotype designation by the author in this publication.

The plates of the whole moths have been arranged, as far as possible, so that figures of externally similar types are grouped together. The figures of genitalia have been arranged in two series—a male series and a female series, each corresponding in sequence (with a few minor exceptions) to that of the moth figures. All photographs and drawings illustrated are of the type-specimens described in the text.

ACKNOWLEDGMENTS.—I am again indebted to Dr. R. S. Cowan, Director of the National Museum of Natural History, where I carried out the work preliminary to the present study during a visit to the Department of Entomology in 1966–1967. I should especially like to thank Dr. W. Donald Duckworth, who provided valuable help in administrative matters and in the final stages of the preparation of the manuscript, Mr. W. D. Field who answered my numerous letters so diligently, and Dr. D. R. Davis. My thanks are also due to Drs. E. L. Todd and R. W. Hodges of the United States Department of Agriculture. Mr. W. H. Rowe’s technical assistance also greatly eased my task while in Washington.

During certain later stages of this work, I was supported under the Visiting Museum Specialist Program of the Carnegie Museum, Pittsburgh. My grateful thanks are due to the Director, Dr. M. G. Netting, to Dr. J. L. Swauger and Mr. W. W. Woodside, to the staff of the Section of Insects and Spiders—Dr. G. Wallace, Mr. H. K. Clench and Mr. J. Bauer—and to everyone who made me so welcome. My then neighbours, Harry Clench and his wife Mary, could not have been kinder.

I have benefitted from discussions on a variety of taxonomic and nomenclatural matters with my colleagues, D. Stephen Fletcher, Ian W. B. Nye, Paul E. S. Whalley, and Klaus Sattler. My assistant, Maureen Grogan, provided impeccable support, and merits the highest praise. She is responsible for all the line drawings.

I am grateful to Mr. H. R. Pearson, Rio de Janeiro; Dr. H. Reichardt, Departamento de Zoologia, São Paulo; and the late Dr. J. F. Teixeira de Freitas, Instituto Oswaldo Cruz, Rio de Janeiro, who provided copies of Brazilian publications that had been difficult to trace in Britain.

With few exceptions, the photographs of the moths were taken by the staff photographers of the National Museum of Natural History. Most of the genitalia photographs were prepared by the Photographic Studio of the British Museum (Natural History) under the supervision of Peter Green. They were prepared chiefly by Jim Brown, who undertook this formidable task with unvarying tenacity. Peter York provided some excellent ‘last-minute’ photographs.

Tina Adams typed the manuscript with commendable speed and accuracy.

Publication in Smithsonian Contributions to Zoology

Manuscripts for serial publications are accepted by the Smithsonian Institution Press, subject to substantive review, only through department’s 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.

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, including 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 an entry, use a period-dash (.—) to separate each reference. Enclose with square brackets any annotation in, or at the end of, the entry. For references within the text, use the author-date system: “(Jones, 1910)” and “Jones (1910).” If the reference is expanded, abbreviate the data: “Jones (1910:122, 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.

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 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. An instruction booklet for the preparation of illustrations is available from the Press on request.

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,” “plates,” “pages.”

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.
