PREFACE. 
I' or some time past the need of a Directory of persons interested 
in the study of Entomology has been keenly felt, and several years 
ago its preparation was begun ; but for various reasons was tempo- 
rarily abandoned. 1 he present volume represents an immense 
amount of work and considerable expense, as every effort has been 
made to communicate with entomologists and students in this coun- 
try and Canada to secure absolutely correct data. Many of our circu- 
lars have received no attention, but. as the majority of these thus 
treated represent people who take little, if any, interest in the sub- 
ject, the omission of their names cannot be greatly regretted. 
As inquiries are constantly made for publications on entomologi- 
cal subjects, a list of such papers as can be supplied by the Society 
only, of course, so long as copies are in stock — is given on page 
68, together with the prices. 
It is hoped that this volume will stimulate a renewed interest in 
Entomology, and create a more fraternal feeling among those en- 
gaged in the study. It should prove of great value to those wishing 
to exchange specimens, and those desirous of obtaining information 
from the various parts of the country. It is to be hoped that ento- 
mologists and others interested will recognize its value, and if the 
proper support is given, a supplement containing changes of ad- 
dress, new names, etc., and any other information of value, will be 
published at least annually, and for this purpose we will thank 
our readers for any additional data they can supply towards a more 
complete edition.
