When Professor Femald began teaching at the Massachusetts Agri- 

 •cultural College, his principal lines of instruction were Zoology, Physiol- 

 ogy, and many other subjects which had no special relation to natural 

 history. He toiled unremittingly to build up and develop his depart- 

 ment and being especially interested in insects, gradually succeeded in 

 developing a department of entomology in that institution. 



Beginning with no facilities whatever for the work, he succeeded in 

 securing gradual improvement from time to time and prior to his 

 retirement from active service, was able to see a modem, fire-proof 

 building, constructed and equipped for class-room and laboratory work 

 in entomology and zoology, which will now be known as Femald Hall. 



His son, Dr. Henry T. Femald, has been connected with the institu- 

 tion for a number of years, and on the retirement of his father, became 

 the head of the department. 



Professor Femald specialized particularly in Micro-Lepidoptera, a 

 group requiring high technical skill and unlimited patience to master 

 successfully. His published works on these insects are models of detail 

 and accuracy. He was a member of many scientific societies and was 

 president of the American Association of Economic Entomologists in 

 189(3. 



While all these achievements were notable, perhaps his greatest 

 success was as a teacher. Few men who had any desire to learn or any 

 interest in the subjects which he taught, could fail to be inspired by 

 him. In this respect he was a master, as all of his former students will 

 readily agree. 



His kindly interest in all with whom he came in contact, will never 

 be forgotten, and the influences for good that he exerted, not only mark 

 him as a great scientist and teacher, but as a truly great man.

The Coccidae, Tables for the Identification of the Sub-Families, and 

 some of the more Important Genera and Species together with 

 Discussions of their Anatomy and Life History. By Alex. D. 

 MacGillivray, pages i-viii, 1-5U2, Scarab Co., Urbana, 111., 1921. 

 This is a comprehensive, morphological, taxonomic and critical account with keys 

 to the sub-families, tribes, most genera and a large number of species. There are 

 also outlines of the life history in the various groups and brief discussions of the 

 economic status of the different forms. The author has compressed within the 

 limits of a moderate sized volume, a summation of practically 50 years of investiga- 

 tion and study by numerous entomologists and has succeeded in producing a work 

 indespensable to all students of the Coccidae and one of great service to entomologists 

 with a less direct interest in the group, because it gives within a small compass an 

 excellent digest of available information.
