118 THE ENTOMOLOGIST. 
in the year 1854 it was resolved to appoint a separate curator 
for the entomological department, and Dr. Snellen van Vollen- 
hoven was appointed to the post. He retained this appointment 
for nineteen years, and they who have had the opportunity of 
inspecting the treasures of that collection will be best able to 
testify to the value of the labours of its late curator. Unfor- 
tunately, in the year 1873, the state of his health obliged him to 
relinquish this post. Dr. Snellen van Vollenhoven was the author 
of numerous scientific works on Entomology: these were nearly 
all illustrated by plates of great excellence from his own 
drawings. Among his principal works may be mentioned :— 
‘ Hemiptera-Heteroptera Neerlandica,’ ‘Essai d'une faune Ento- 
mologique de l'Archipel Indoneerlandais,’ ‘ Schetsen ten gebruike, 
bij de Studie der Hymenoptera,’ and ‘ Pinacographia,’ the latter work, 
of which but eight parts appeared, being an illustrated description 
of the Ichneumons of North-West Europe. ‘T’o these were added 
numerous important papers in the Transactions of the Netherland 
Entomological Society, and contributions to the continuation of 
Sepp’s well-known work on the butterflies of the Netherlands, 
which he edited up to the time of his death. His life-histories of 
sawflies are well known to British entomologists, a considerable 
part of this work having been translated in the pages of this 
periodical. Among entomological works of a more popular 
character may be mentioned his ‘ Gelede dieren san Nederland, 
and a volume on the metamorphoses of insects. His last work 
was a biography of P. Lyonet, which appeared last year in the 
‘Album der Natuur.’—J. W. M. 
Besides the lamented Dr. van Vollenhoven we regret to notice 
the deaths of the following eminent entomologists :— 
Lropotp Krrcouner, the Bohemian hymenopterist, died at 
Kaplitz on the 29th of last December. He was the author of the 
‘Catalogus Hymenopterum Europée,’ which was issued under the 
auspices of the Vienna Natural History Society. The necessity 
for this work is shown by its being already out of print, although 
only published in 1867. Its use, however, would have been 
greater if it had been more carefully compiled, as in many 
families it is a mere alphabetical list of used names, without any 
attention to synonymy; obsolete and duplicate genera also 
frequently find a place. Records of parasitism and geographical
