B. Graduate. 



Graduate students taking entomology as a major subject are ex- 

 pected to have received the undergraduate work given at the Massa- 

 chusetts Agricultural College, or its equivalent, or to make up that 

 work before receiving credit for advanced work. Students for the 

 degree Ph. D. are required to spend at least three years in residence, 

 devoting at least twenty hours per week to the work. Students taking 

 entomology as a minor subject are required to spend from twelve to 

 sixteen hours each week for a year and a half. 



The importance of some knowledge of all aspects of entomology 

 to the professional entomologist is recognized by giving courses of 

 lectures to the graduate students on the subjects named below. It is 

 not implied that these courses are all by any means exhaustive, but 

 rather that in connection with about 15,000 pages of required reading, 

 each student will acquire a fair knowledge at least, of all aspects of 

 his profession. In addition to this he will be expected to specialize 

 in certain lines and to prepare a thesis, generally in two or three 

 subjects, which will be not only original, but a distinct contribution 

 to knowledge. His special work may include some subject in mor- 

 phology, the systematic classification of some group, the preparation 

 of the life history of some insect and some problem connected with 

 insect control, the relative proportion between these topics being de- 

 pendent upon circumstances. 



Frequent seminars, at which reports on current literature, im- 

 portant general topics, and subjects assigned for report by the teachers, 

 are also held, and the student is expected to acquire familiarity with 

 the literature of entomology and to learn how to abstract and present 

 the results of his reading and work. 



The following list of topics is presented to graduate students, 

 either by lectures or by laboratory or field training, in addition to 

 the thesis work. 



Morphology. — Embryology ; life history and transformations ; his- 

 tology; phylogeny and the relation of insects to other arthropods; 

 hermaphroditism ; hybrids ; parthenogenesis ; pedogenesis ; heterogamy ; 

 chemistry of colors of insects; luminosity; deformities of insects; 

 variation; duration of life. 



Ecology. — Dimorphism ; polymorphism ; warning coloration ; mim- 

 icry; insect architecture; fertilization of plants by insects; instincts 

 of insects; insect products of value to man; geographical distribution 

 in the different f aunal regions ; methods of distribution ; insect migra- 

 tion ; geological history of insects ; insects as disseminators of disease ; 

 enemies of insects, vegetable and animal, including parasites. 



Economic entomology. — General principles ; insecticides ; appa- 

 ratus; special cases; photographs of insects and their work; methods 

 of drawing for illustrations; field work on insects and study of life 

 histories; legislation concerning insects.
