PREFACE. 
eeeeeieeneeee 
alee object of issuing the Departmental Notes on 
Insects that affect forestry in India in their present 
form is to enable the Officers of the Department and others 
interested inthe culture of trees to keep up to date with 
our knowledge of the subject and to assist the advance- 
ment of the work by studying the still unknown portions of 
the life-histories of the various pests detailed and of 
others still unrecorded. To this end, criticism and dis- 
cussion are cordially invited. 
Several of the insects dealt with are new to science, 
and most of the information on their habits, etc., is new. 
It has not been considered necessary here, however, to 
give in full detail the reasons for the statements made 
with reference to some of the new and more complex of 
the life-histories. The author hopes to publish elsewhere 
full and detailed technical papers dealing with the matter 
from the scientific standpoint. 
It is proposed to give information in these notes upon— 
i—Hurtful Insects. 
ii,—Useful Insects. 
Owing to queries received on the subject it should, 
perhaps, be pointed out that the descriptions of the 
insects do not aim at being scientific ones, they having 
been drawn up merely as simple aids to identifying the 
insects by fellow-workers in the field. It is hoped 
that the new species will be described with the help of{ 
scientific confréres. The writer rusts in time to himself 
deal with the Scoly¢ide, of which considerable collec- 
tions of unknown species have already been made.
