in Majorca and Spain (1g01) by the Professor, Mr. Holland 
and Mr. Hamm. This too is now nearly complete. Mr. 
Hamm’s time was also much occupied in preparing cabinet 
drawers, mounting specimens, and labelling for Colonel Yer- 
bury’s invaluable work upon our collection of Diptera, and 
also in specially preparing specimens to be photographed 
for the plates accompanying memoirs which have been written 
in the Department during the year. Other pieces of work 
are sufficiently indicated in the record of catalogued accessions 
which is given on pp. 20-22. Among these I must specially 
allude to the large amount of work which has been expended 
upon the valuable collection of British Coleoptera presented 
by Horace S. J. Donisthorpe, Esq. Precise data accompany 
all the specimens, but each form of label only applies to com- 
paratively few, so that in printing, the type required to be 
altered hundreds of times for date or locality or both. The 
resetting of the old collection has unfortunately been entirely 
at a standstill during the year. 
Dr. Dixey has now arranged the whole of the Pzerinae 
in five 60-drawer cabinets. The work must not, however, 
be regarded as complete save for the incorporation of new 
material as it is received, for Dr. Dixey has set so high 
a standard in this part of our collection that considerable 
time must still elapse before the labour on the existing 
specimens is finished. It must be still many months before 
the instructive maps, which show at a glance the distribution 
of genera and species, will have been coloured and fixed in 
their places. The determination of the boundaries of the area 
of distribution of each species and genus involves prolonged 
and patient inquiry, and yet the result when expressed in 
colour on a map can be comprehended almost at a glance. 
Colonel Swinhoe completed the arrangement of the Pyrales 
just before leaving Oxford. I take the opportunity of again 
saying that the warm thanks of the University are due to him 
for all that he has done for the Hope Collection of moths, 
during the many years of his residence in Oxford, and for the 
large number of specimens which he has added to the col- 
lection.
