To further promote the end in view I would suggest the following 
division of the general subject : 
(1) Staple and miscellaneous crop insects. 
(2) Small fruit and truck crop insects. 
(3) Deciduous fruit tree insects, including those infesting nursery stock. 
(4) Citrus and subtropical fruit insects. 
(5) Ornamental plant and greenhouse insects. 
(6) Shade tree and forest insects. 
(7) Insects injurious to stored foods, dwellings, clothes, books, and mis- 
cellaneous substances. 
(S) Insects affecting man and the domestic animals. = 
(9) Insects concerned in the transmission and carriage of disease. 
(10) Beneficial parasitic and predaceous insects. 
(11) Insects useful to man as furnishing food, clothing, ete. 
(12) Insecticides and machinery. 
-A most commendable feature of our present-day literature is the 
increasing amount of thorough and painstaking work on the biology 
of insects. Shortly after the establishment of the several agricultural 
experiment stations entomological publications were, probably of 
necessity, largely compilations, owing to the fact that there was need 
for placing before the public for immediate use such information 
covering injurious species as had already been obtained. As informa- 
tion of this character has become more and more familiar, its presen- 
tation and repetition have become less necessary, and more original 
work has been brought forth. Revised bulletins on insecticides and 
spraying machinery must of necessity be gotten out from time to 
time as progress 1s made along these lines, but the notable decrease 
of purely compiled bulletins and papers concerning insects 1s a most 
favorable indication. 
Many recent entomological publications, in the quality of subject- 
matter, character of illustrations, and wealth of detailed observations 
feave little to be desired. Improved facilities for careful hfe-history 
work have rendered possible the many excellent papers which are at 
once a credit to the literature of the science and an inspiration to 
other workers. Careful life-history studies have been an important 
means of separating two or more species long held to represent but 
ene. Witness the case of the aphids designated as Aphis mali, which 
Sanderson has shown represent several species. Similarly, Morrill 
has been able to separate Aleyrodes packardi from Aleyrodes vapora- 
riorum. Certain species may only be distinguished by a compara- 
tive study of their respective larval stages, as in the case of Chilocorus 
bivulnerus and C’. similis. 
In addition to careful biologic studies of insects, the consideration 
of life zones, of effective temperatures, and of the number of genera- 
tions in various parts of the country, of forms widely distributed 
should be given more attention than has been the case in the past.
