Entomologist who got his education at Amsterdam University; he was appointed teacher in Natural History at Amsterdam in 1923, took his Ph.Dr’s degree in 1930,1 and subsequently went to Java, where he was attached to several secondary schools, viz at Bandoeng, and Batavia; in 1946 Lecturer of Zoology in the University of Indonesia; in 1948 on leave in Holland; in 1949 Professor at Bandoeng.

In 1921/22 he was leader of the zoological-botanical section of a scientific expedition to Boeroe. The latter was executed under the auspices of the Roy. Dutch Geogr. Society and the Treub Society, supported by the Indian Committee for Scientific Researches. It aimed at performing subsequent researches to Rutten’s geological investigations in that island, by the geologist Henny; Toxopeus was to make the botanical and zoological collections. They were assisted by Mr and Mrs Estrin (Russians) and two mantris of the Buitenzorg Botanic Gardens.2

In 1938/39 he joined the 3rd Archbold Expedition to Dutch New Guinea (cf. sub Brass), making exclusively zoological collections.3

He is the author of several entomological papers. J.J. Smith named some plants after him (cf. Backer, Verkl. Woordenb., 1936).
