Biographical & Type Information - D

Dahlbom, Anders Gustav (b. Mar. 3,1806, Ostgothland; d. May 3, 1859, Lund) - Pupil of Zetterstedt. Collection was deposited in the Lund Museum; but some types can also be found in NHRS, Copenhagen, or ZMHB. Citations: Anonymous (1859a, b) and Ratzeburg (1874).

Dallas, William Sweetland (b. Jan. 31, 1824, London, England; d. May 28, 1890, London, England) - His should be deposited in the British Museum of Natural History (BMNH), but some are missing. Dallas indicated which sexes he had before him, but he did not indicate how many of each sex. He also gave measurements of length and sometimes width. If the measurements were given as a range for one or both of the sexes, then this would indicate more than one ST. He also, at the end of the description, would list individual collection sites (or different collections from same site) by letter. Once again, this gives an indication of how many specimens he had before him. If he listed only one sex, the measurements are not given as a range, and only one collection site is listed, he probably described the species from a single specimen, but in a couple cases such as this several STS have been located. Strictly speaking, none of his types should be considered HTS, and LTS should be designated for all species. Citations: Anonymous (1890a, b), Francis (1890), Hartwig (1890), McLachlin (1890), Wilderman (1890), and Musgrave (1932).

De Carlo, Jose Alejandro (b. 1896; d. June 19, 1983) - Worked primarily on Nepomorpha. Collection should be in Museo Argentino de Ciencias Naturales, Argentina (MACN). See Bachman (1983, 1985) for biographical information.

DeGeer, Carl (b. Feb. 10, 1720, Finspang, Sweden; d. Mar. 8, 1778, Stockholm, Sweden) - Educated in the Netherlands; later studied under Linnaeus. Published 20 papers of which most important were the Mťmoirs pour servir B líhistoire naturelle des Insectes (1752-1771). Collection is conserved in the Naturhistoriska Riksmuseet, Stockholm, Sweden (NHRS); it also contains some Linnaean types (those in which Linnaeus mentioned either DeGeer or Rolander in the original description). It is impossible in most cases to determine how many specimens DeGeer had when he made his original descriptions. In some cases, he describes both male and female specimens without designating a type. All types should be considered as STS until proper LTS can be designated. Dolling et al. (1999) provided information on the Heteroptera contained in DeGeerís 1773 (vol. 3) and 1778 (vol. 7) Mťmoires pour servir B líhistoire des Insectes. See Ossiannilsson (1953) for a list of Linnaean types from the DeGeer collection which are residing in UZIU. Citations: Dumťril (1823), Swainson (1840), Jardine (1848), Rose (1850), Miall (1895, 1912), Dow (1913), Howard (1930), Essig (1931), Wheeler (1931), and Bonnet (1945).



Dejean, Pierre FranÁois Marie Auguste (b. Aug. 10, 1780, Amiens, France; d. Mar. 17, 1845, Paris, France) - Mainly a Coleopterist, Dejean was an avid collector. His collection was eventually divided and passed through the hands of various workers. Specimens now reside in various collections: British Museum (BMNH), Turin, Lyon, Barcelona (IMBS), and others. Horn et al. (1990) indicates that the Hemiptera specimens traveled via Carreno to the Mus. Munic. Cienc. Nat. Barcelona (MZBS?). Citations: Swainson (1840), Boisduval (1845), Hope (1846), Kraatz (1874), Marseul (1883), Dow (1913, 1914), Howard (1930), Essig (1931), Musgrave (1932), and Arnett (1948).

De Jonck, Albert (b. ?; d. ?) - Hemipteran types from Congo went to H. Schouteden, then to the Musťe Royal de líAfrique Centrale, Tervuren, Belgium (MRAC).

Deschamps, Daniel - (b. ?; d. ?) - H&K: "Hemipt. d. Seine-Infťrieure an Mus. Hist. Nat., Rouen."



Dispons, Paul (b. 1906; d. May 2, 1972) - Many papers on the Reduviidae. PI: Musťum National díHistoire Naturelle, Paris, France (MNHN). Citation: Carayon (1972).





Distant, William Lucas (b. Nov. 12, 1845, Rotherhithe, SE London, England; d. Feb. 4, 1922, Wanstead, England) - Father was a whaling captain; in fact, described by Distant as the most eventful day of his life, on Aug. 5, 1867, he set out on a whaling mission to the Malay Peninsula. This trip sparked his interest in Natural History, and resulted in the publication of Rhopalocera Malayana (1882-1886), a description of the butterflies of the Malay Peninsula. Distant became associated with the tanning business which led him to a 12 month trip to South Africa (1890-1891). He returned to South Africa a few years later. These trips resulted in publication of A Naturalist in the Transvaal (1892), and Insecta Transvaaliensia (1900-1911). He became a part-time Assistant at the British Museum (Natural History) in 1899, and during the next 21+ years, he re-arranged the National Collection, and described many new species found in this collection. Notable heteropteran publications include Volume I of the Heteroptera and part of Volume I of the Homoptera of the Biologia Centrali Americana (1880-1900), and the Hemiptera volumes of the Fauna of British India (1902-1918). Death came after a long battle with cancer.  Distantís collection (some 50,000 specimens and over 2500 types) was brought to the British Museum (Natural History) in 1911; its purchase by the BMNH was completed by 1920. So, unless indicated otherwise, all of Distantís types are located in the BMNH. Some of his work from India indicates that some of the STS were deposited in the Calcutta Museum. These were in conjunction with work with Atkinson; Distantís later papers indicated that Atkinsonís specimens might now be in the BMNH. Specimens from Burma listed in the Fea collection are probably in MCSN. In the Biologia Centrali Americana work references to Mus. Berol. probably refer to ZMHB.  In most cases, there is no way to tell how many specimens Distant had before him when he made his original descriptions. In some cases, it is obvious that he had more than one (measurements given as a range, more than one locality given, more than one museum depository listed, discusses a variety, etc.). If none of these conditions were present, he probably only had a single specimen. In many of these cases, someone has placed a "type" label on the specimen or one of the specimens, so many modern day workers have referred to this specimen as the HT. LT designations are probably still needed.  Distant also did a curious thing when it came to generic type designations. In many cases, he designated a generic type that was not an original member of that genus; thus, most of these designations are now considered to be invalid. But, in most cases, the species designated as type is simply a senior synonym of an original member of the genus. When a candidate species for type had been placed as a junior synonym of another species, Distant, rather than citing the junior synonym as the type of the genus, would cite the senior synonym. Strict adherence to the rules of nomenclature would dictate that we consider these type designations invalid, but perhaps this should be revisited. Some of Distantís designations were better choices than some later designations.  See Dolling (1991) for a bibliography and biographical information.

Much of his non-British collection was purchased by Alexander Macleay whose collection eventually formed the foundation of the Macleay Museum in Sydney, Australia (MAMU).

Douglas, John William (b. Nov. 15, 1814, Putney, England; d. Aug. 28, 1905, Harlesden, England) - Along with J. Scott, published The British Hemiptera 1. Heteroptera (1865), and they compiled a catalog of the British Heteroptera (1876). Most of his collection now contained in the Oxford University Museum (OXUM); perhaps a few specimens in BMNH. Citations: Anonymous (1905a, b), Merrifield (1905), Saunders (1905), and Dale (1906).

Drake, Carl John (b. July 28, 1885, Eaglesville, OH, USA; d. Oct. 2, 1965, Washington, DC, USA) - World authority on the Tingidae; published (with Ruhoff) World catalog of the Tingidae (1965). Collection and considerable estate donated to the National Museum of Natural History (USNM). Citations: Anonymous (1966), Arnaud (1966), Froeschner (1966), Gurney & Kramer (1966), Andre (1967), Ruhoff (1968), and Mallis (1971).

Drury, Dru (b. Feb. 4, 1725, London, England; d. Jan. 15, 1804, Turnham Green) - Father was a silversmith; Dru took over the business in 1748; retired in 1789 to devote entire time to entomology. From 1770-1787, he published the three volume set called Illustrations of Natural History, Wherein are Exhibited Upwards of 240 Figures of Exotic Insects. Drury was an avid collector, containing over 11,000 specimens.  Collection was auctioned, and much of it may now be lost; some Lepidoptera types may be in the British Museum (BMNH). Dolling et al. (1999) provided information on the Heteroptera species contained in Druryís 1770 Illustrations of Natural History.
