Pieter Snellen was a merchant and entomologist in Rotterdam,
writing monographs in the journal
Tijdschrift voor Entomologie, which were sometimes illustrated.
For these ilustrations: he chose artists to draw them such as
Dr. Johannes Jeronimus Coster,
and these engraved and lithographed
by the renowned A.J. Wendel & Co.,
and printed by P.W.M. Trap.
