Amsterdam, Nederlandse Entomologische Vereniging (NEV), 1966-1979. 20 papers in 20. 8vo (24.0 x 16.0 cm). About 330 pp.; numerous illustrations. Partly in original printed wrappers, partly published without wrappers.

A collection of offprints of hymenopterological papers by the Dutch entomologist Jan Pieter van Lith (1912-1979), dealing with thread-waisted wasps in particular. Including a 4-page obituary, listing all his 55 papers, by H. Wiering. The present set consists of his later, more systematical works, forming an uninterrupted run of 19 contributions from 1966 onwards. His earlier contributions were mainly faunistic. All but one were published in the NEV's Tijdschrift voor Entomologie; a single one was published in Steenstrupia. Sizes vary a bit. An excellent, clean set.
