his personal observations between 1899 and 1929, and his principal earlier 
references were included. Section I would have been unduly enlarged had we 
included the Robertson references under each plant family, thus our decision to 
give these references a special category. Many other references of Robertson 
not included here treat phenology, evolution of entomophilus flowers, and 
anthecology. They can be found in Ecology, Scientific Monthly, Psyche, and the 
American Naturalist. 
Section III contains a list of general references to phytophagous insects. 
Some individual reports contain many sections treating svecific plant—insect 
associations such as the work by Packard (1890) on shade tree insects, Craighead 
(1950) on eastern forests, and the companion work by Keen (1958) on western 
forests. Others are valuable sources of more general associational data 
involving plant associes such as prairies (Hendrickson, 1930, 1931; Vestal, 
1913), hammocks (Dozier, 1920), and swamps. The works of Brues (1946) and Frost 
(1959) are basic works including general treatments of phytophagous insects, and 
they contain extensive bibliographies. 
Section IV includes principal references to the phytophagous food habits of 
several insect orders. Peterson's excellent manuals of insect larval forms 
(1948, 1951) include extensive food plant lists of the insect orders treated. 
The list of references under this section is by no means complete, but it will 
give the worker a basis for further bibliographical searching, especially at the 
insect family level.
