English entomologist
Oliver Erichson Janson (1850 – 25 November 1925) was an
English
entomologist who specialised in
Coleoptera.
He was the son of
Edward Wesley Janson and took over the family natural history and publishing business.
Janson's early years were spent at
Fortis Green, and he collected beetles there and at
Finchley,
Hampstead and
Highgate.
In 1906 he made an expedition to
Iceland adding to the collections of the
National Museum of Iceland
During the
First World War he made three trips to Ireland, particularly
County Kerry.
Janson was a world authority on
Cetoniinae publishing new genera and species mostly in Cistula Entomologica published by Janson and Co.
His world collection was purchased by
Titus Valck Lucassen. His collection, in turn, was acquired by the
Rijksmuseum van Natuurlijke Historie at Leiden in 1940.
He was a
Fellow of the
Royal Entomological Society from 1869 until his death.
