Centuria Insectorum (Latin, "one hundred insects") is a 1763 taxonomic work by Carl Linnaeus, and defended as a thesis by Boas Johansson; which of the two men should for taxonomic purposes be credited with its authorship has been the subject of some controversy. It includes descriptions of 102 new insect and crustacean species that had been sent to Linnaeus from British America, Suriname, Java and other locations. Most of the new names included in Centuria Insectorum are still in use, although a few have been sunk into synonymy, and one was the result of a hoax: a common brimstone butterfly with spots painted on was described as the new "species" Papilio ecclipsis.
The contents of the work were published twice, under two slightly different titles. Centuria Insectorum Rariorum ("one hundred rare insects") was published as a standalone thesis, while Centuria Insectorum was published as part of Linnaeus' series of Amoenitates Academicæ ("academic delights"). Both bear the date June 23, 1763, although the latter was printed later, in September 1763. [1]
Since Centuria Insectorum Rariorum was a thesis presented and defended by one of Linnaeus' students, Boas Johansson (1742–1809) from Kalmar, it has been argued that authorship of the taxa named in it should be assigned to Johansson. The authorship, however, has been the subject of some controversy. [1]
Several lines of argument have been used to suggest that Linnaeus should be considered the author. The role of the person defending the thesis at Swedish universities at the time was to prove his command of Latin, and responsibility for the text of the thesis rested mainly, if not entirely, with the professor. [1] Linnaeus appeared to consider himself the author, referring in his later works to Amoenitates Academicæ without including an abbreviation for the author, as he did for works written by other people. [1] Works presented by students of other taxonomists of the era (such as Carl Peter Thunberg, Adam Afzelius and Elias Magnus Fries) are generally credited to their supervisors, and not the students themselves. [1] Finally, most zoologists, and "Scandinavian authorities on Linnaeana" consider Linnaeus the author; [1] in the interests of nomenclatural stability, it is preferable to continue doing so. The issue was raised in a petition to the International Commission on Zoological Nomenclature and, although a large majority voted in favour of recognising Linnaeus as the author, the one dissenting vote caused the commission to defer its decision. [2]
The specimens used by Linnaeus or Johansson in writing Centuria Insectorum include some provided by Dr Alexander Garden, a horticulturist from Charles Town in the Province of South Carolina, [3] by Carl Gustav Dahlberg in Suriname, [4] by Hans Johan Nordgren in Java, [5] and from the collection of Baron Charles De Geer from the Province of Pennsylvania.
The dissertation begins by discussing improvements that the Linnaean system of taxonomy has brought to the study of insects, before describing the new species. [6]
One of the species described in Centuria Insectorum was "Papilio ecclipsis". This was based on a specimen sent by William Charlton to James Petiver in 1702, who wrote: "It exactly resembles our English Brimstone Butterfly (R. Rhamni), were it not for those black spots and apparent blue moons on the lower wings. This is the only one I have seen." [7] Carl Linnaeus examined the butterfly, and named it Papilio ecclipsis in Centuria Insectorum Rariorum, including it in his Systema Naturae from the 12th edition (1767) onwards. [7] It was not until 1793 that the hoax was discovered by Johan Christian Fabricius, who recognised that the dark patches had been painted on, and that the specimen was a common brimstone butterfly (now called Gonepteryx rhamni). Although the curator at the British Museum "indignantly stamped the specimen to pieces" when he found out, William Jones created two replicas to replace the lost specimen. [7]
The 102 species described in Centuria Insectorum were divided into seven sections, broadly corresponding with modern insect orders. Exceptions are that thrips (Thysanoptera), mantises (Mantodea) and Orthoptera were included in the Hemiptera, dragonflies (Odonata) were included in the Neuroptera, and the section called "Aptera" contains crustaceans rather than insects in the modern sense. Most of the names introduced in Centuria Insectorum are still in use, albeit in different genera; in a few cases, it is not clear what animal the name refers to. [Note 1]

Johan Christian Fabricius was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification.
Entomology, the scientific study of insects and closely related terrestrial arthropods, has been impelled by the necessity of societies to protect themselves from insect-borne diseases, crop losses to pest insects, and insect-related discomfort, as well as by people's natural curiosity. Though many significant developments in the field happened only recently, in the 19th–20th centuries, the history of entomology stretches back to prehistory.
Acheta is a genus of crickets. It most notably contains the house cricket. According to Direction 46 issued by the ICZN in 1956, this generic name is masculine in gender. Apart from the cosmoplitan house cricket, species are recorded from the Palaearctic realm and North America.
Conchaspis capensis is a species of scale insect from South Africa found on Metalasia muricata and Phylica species. It was originally described by Carl Linnaeus in his 1763 work Centuria Insectorum.
Hepatus epheliticus, known by various names, including the calico crab and Dolly Varden crab, is a species of crab. It lives in shallow water in the western Atlantic Ocean from the Chesapeake Bay to the Dominican Republic. It has a 3-inch (76 mm)–wide carapace adorned with large red spots with darker outlines.
Catopsilia scylla, the orange migrant or orange emigrant, is a species of butterfly that lives in South East Asia and Australasia. Its larvae feed predominantly on plants of the genera Cassia and Senna.
Chauliodes pectinicornis known as Summer fishfly, is a species of fishfly from North America.
Monobia quadridens, also known as the four-toothed mason wasp, is a species of solitary potter wasp found in North America. It grows to a wingspan of 18 mm (0.71 in), and feeds on small caterpillars and pollen. Two generations occur per year, with one generation overwintering as pupae.
The 10th edition of Systema Naturae is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of Species Plantarum.
In the 10th edition of Systema Naturae of 1758–1759, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". He described the Insecta as:
A very numerous and various class consisting of small animals, breathing through lateral spiracles, armed on all sides with a bony skin, or covered with hair; furnished with many feet, and moveable antennae, which project from the head, and are the probable instruments of sensation.
In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with hardened wing covers were brought together under the name Coleoptera.
Entomologia Carniolica exhibens insecta Carnioliae indigena et distributa in ordines, genera, species, varietates is a taxonomic work by Giovanni Antonio Scopoli, published in Vienna in 1763. As well as describing hundreds of new species, Entomologia Carniolica contained observations on the species' biology, including the first published account of queen bees mating outside the hive.
Caryobruchus gleditsiae is a species of beetle in the family Chrysomelidae. It lives in North and Central America and develops inside the seeds of palm trees. Adults grow to a maximum length of 11 mm (0.43 in), the size depending on the size of the seed it grew up in. The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.
Omocerus bicornis is a species of tortoise beetle from South America. It lives on Cordia (Boraginaceae) plants, and is found in Brazil, Suriname, French Guiana, Suriname and Venezuela. It was first described by Carl Linnaeus in his 1763 work Centuria Insectorum under the name Cassida bicornis, and was later made the type species of the genus Omocerus by Philogène Auguste Joseph Duponchel and Alcide d'Orbigny in 1843.
Pseudophasma brachypterum is a species of stick insect found in Brazil, Suriname, Guadeloupe and Peru.
Eugaster spinulosa, a species of bush-cricket from Morocco.
Nemognatha chrysomeloides is a species of oil beetle (Meloidae) endemic to Central and South America.
Cethosia cydippe, the eastern red lacewing, is a species of butterfly from Australia, New Guinea and nearby islands. The Australian subspecies, C. c. chrysippe, is known as the red lacewing butterfly.
The 12th edition of Systema Naturae was the last edition of Systema Naturae to be overseen by its author, Carl Linnaeus. It was published by Laurentius Salvius in Holmia (Stockholm) in three volumes, with parts appearing from 1766 to 1768. It contains many species not covered in the previous edition, the 10th edition which was the starting point for zoological nomenclature.
Papilio ajaxLinnaeus, 1758 is a scientific name given in 1758 by Linnaeus to what later appeared to be a combination of three species of butterflies. The name was placed on the Official Index of Rejected and Invalid Specific Names in Zoology in 1954 after an application to that matter was submitted by Steven Corbet in 1945. The name no longer has a status as a scientific name, except in cases of homonymy; according to the rules of the International Code of Zoological Nomenclature the name Papilio ajax can no longer be given to any species.
