1914] Notes on Some Old European Collections. 93 
Though not one of the old collections, that of Achille 
Costa may be mentioned. This is now at the University of 
Naples, where it is kept in a room by itself. There is no 
entomologist at the University and the collection is in charge 
of the Professor of Parasitology, but it is in excellent con- 
dition and apparently well cared for. 
Many other old collections may be found in different 
parts of Europe, but not having paid particular attention to 
them they are not touched upon here. It is noticeable nearly 
everywhere that these collections are for the most part kept 
in trays so open that in this country a single year would probably 
see their complete destruction by museum pests. These 
nuisances do not appear to be very important abroad or the 
priceless collections of Linne, Fabricius and others would long 
ago have become mere heaps of dust at the bases of the pins. 
DISCUSSION. 
Dr. Howard said in discussion that there is so much of 
value in information of the character of that contained in 
Dr. Fernald’s paper, that he was emboldened to add two state- 
ments: First, that the bulk of the collection of A. H. Haliday, 
the brilliant Irish entomologist, is now carefully preserved by 
Prof. G. H. Carpenter in the College of Agriculture, in Dublin; 
Second, that the Ratzeburg types are preserved like religious 
relics by Dr. Eckstein at the forest school at Ebersiwalde bei 
Berlin.
