English entomologist (1850–1925)
Oliver Erichson Janson (1850 – 25 November 1925) was an Englishentomologist who specialised inbeetles.
He was born in 1850, the son ofEdward Wesley Janson. Janson's early years were spent atFortis Green, and he collected beetles there and atFinchley,Hampstead andHighgate. In 1906, he made an expedition toIceland adding to the collections of theNational Museum of Iceland. DuringWorld War I, he made three trips to Ireland, particularlyCounty Kerry. Janson was a world authority onCetoniinae publishing new genera and species mostly inCistula Entomologica published by Janson and Co. His world collection was purchased byTitus Valck Lucassen. His collection, in turn, was acquired by theRijksmuseum van Natuurlijke Historie at Leiden in 1940.
