REPORT OF THE SOCIETY 15 



of meteorological conditions on the development and migrations of locusts 

 have appeared in entomological or biological literature. 



The study of other species of locusts is a good one, while the anatomy 

 and histology of the locust are comprehensively treated. It is interesting 

 to note the assistance given by Dr. C. S. Minot, J. H. Emerton, E. Burgess 

 and J. S. Kingsley. 



This great work is monographic in its completeness, deals with a most 

 important economic problem, and is written in a charming style. It is 

 entitled to rank among the first of the great masterpieces of American 

 economic entomolog\^ 



"The Gypsy Moth" by Forbush and Femald 



In my judgment "The Gypsy Moth" by Forbush and Femald, pub- 

 lished in 1896 under the direction of the State Board of Agriculture of 

 Massachusetts, is entitled to a place among the masterpieces of American 

 economic entomology. Mr. Forbush's contribution deals with the intro- 

 duction of the moth into New England, its increase and spread up to 1894, 

 the efforts made to destroy it, and its natural enemies. Dr. C. H. Femald 

 describes its injuries in Europe, and the methods used there to controlit; 

 also the life-history in all its stages, its habits during these stages, its in- 

 ternal anatomy, its natural enemies, and the effects of various insecticides 

 on the larvae. The illustrations, some from photographs taken in the field 

 and others from drawings of anatomical features, are excellent. The 

 bibliography is very exhaustive. 



During the twenty years since its publication little new information 

 has been added to that given in the w^ork. It is quite true that the great 

 experiment of the introduction of foreign parasitic and predaceous insect 

 enemies was launched a few years after the appearance of Forbush and 

 Fernald's publication, but the results do not detract from its monographic 

 completeness. "The Gypsy Moth" stands out as a masterpiece for its 

 thoroughness, completeness and clearness, and in after years when things 

 will be seen in a truer perspective it will in all probability be looked upon 

 as an entomological classic.
