PREFACE 5 
No. 12, describe work which was done before June, 1893, 
but publication itself took place after that date. In all 
Other cases, as well as in a large part of No» 12, the 
researches were conducted between June, 1893, and the 
present date. 
The Reports of the Department for the years 1895 
and 1896 are included as Nos. 18 and 19. It is intended 
to include the Reports of all future years in the forth- 
coming volumes, so that a continuous account of the 
progress of the Department will be registered. 
This volume, and still more the volumes which will 
follow, are the evidence that the Hope Department is 
a centre of activity, and counts as one of the forces which 
are doing important academic work in Oxford, even 
though its part in teaching for examinations must be 
a small one. 
The Plate at the beginning of this volume represents 
the makers of the Hope Department—the Rev. Frederick 
William Hope, F.R.S., who presented his vast collections 
and complete entomological library to the University, 
founded the Chair, and continued until his death to 
purchase fresh materials to add to those which he had 
already given; Ellen Hope, his wife, who carried on the 
work, purchasing and presenting many collections of 
the utmost value, endowed the Keepership of Engraved 
Portraits, the Collections, and Library, and added to the 
endowment of the Chair; and John Obadiah Westwood, 
the first Hope Professor, whose great name and fame 
enriched the Hope Collections from all parts of the world, 
who added largely to them from his own private collec- 
tions, and described an immense number of species, the 
types of which are among the most valued treasures of 
the Department. 
I have to thank Mr. Alfred Robinson, of the Museum,
