INDEX TO INSECT PEST SURVEY BULLETIN 
VOLUME 1,1921 
In the following index to Volume I of the Insect Pest Survey 
Bulletin, all technical names are underlined. Parentheses en- 
closing names of describers, to indicate reference of a species 
to the indicated genus subsequent to the description of that 
species, have been omitted. For convenience of reference, com- 
mon names have "been included in the index, but citations in these 
cases are only indicated by cross reference to the technical 
names. 
It is hoped that the common names used by the Survey will be 
accepted by all working entomologists, and eventually adopted by 
the American Association of Economic Entomologists. We wish par- 
ticularly to urge upon our collaborators the use of these common 
names already accepted by the Association and which should be con- 
sidered as official names by all American Economic Entomologists . 
Dr. W. E. Hooker, who for many years, has reviewed the literature 
on Economic Entomology for the Experiment Station Record, suggests 
the plan followed in this index, of indicating these common names 
approved by the American Association of Economic Entomologists by 
affixing the letters, a. n. o. (americano nomina officinale) and in 
this way directing attention to the desirability of using these . 
approved names. 
The Entomologist in charge of the Insect Pest Survey here wishes 
to acknowledge the assistance he has received throughout the year, 
and particularly, in preparing this index, from the following tax- 
onomists working in the United States National Museum: Mr. E. A. ■ 
Schwarz, Dr. H. G. Dyar, Dr. Carl Heinrlch, Dr. J. M. Aldrich, Dr. 
H. E. Ewing, Mr. A. N. Caudell, Mr. S. A. Rohwer, Mr. R. A. Cushman, 
and Mr. A. B. Gahan.
