ZWART 2 ) With one plate and three text-figures Hat sich nun ein Entomolog um unsre Wissenschaft nicht bloss in seinem engern Vaterlande und amtlichen Wirkungskreise, sondern auch nach vielen und bedeutenden Richtungen im Grossen und Ganzen so hochverdient gemacht wie Samuel Constant Snellen van Vollenhoven, so gebührt ihm ein Zeugniss der dankbaren Anerkennung. C. A. Dohrn, 1881, Stett. ent. Ztg. 42: 371 Abstract The significance of the entomological work of S. C.

C. Snellen van Vollenhoven 3 ) a century has passed since he died: the first truly scien-tific entomologist in the Netherlands. Others had preceded him (e.g., Cramer, Stoll, Voet, Merian, Sepp), but their contributions to Dutch entomology were li-mited from a scientific point of view. Vollenhoven's achievements still keep us ') Rijksmuseum van Natuurlijke Historie, Leiden 2 ) Dept. of Entomology, Agricultural University, Wageningen 3 ) The full family name Snellen van Vollenhoven is in this paper abbreviated Vollenhoven. Vollenho-ven should not be confounded with the Dutch lepidopterist P. C. T. Snellen (1832-1911). 235
