Several things were kept in mind in the preparation of this 

 collection. It was designed primarily to be of the greatest pos- 

 sible value to all those who are obliged to control insects or 

 suffer financial loss; and, to accomplish this, insects injurious 

 to the different crops and to various products were given a very 

 prominent place in the exhibit. These injurious species are 

 also represented, so far as possible, in their different stages, 

 egg, larva, pupa and adult, and any peculiarities of habit 

 (specially those bearing on the character of the injury) are illus- 

 trated. Thus in looking over the exhibit of injurious forms, 

 the visitor has before him an epitome of the life of the depre- 

 dator. He sees not only the insect in its injurious stage but 

 also in its other forms, and in a few moments he can grasp 

 many of the essential facts in the life history of a pest. The 

 illustrations of the work of the injurious species are frequently 

 very helpful in enabling a farmer to recognize the author of 

 what was to him previously a mysterious injury. A catalogue 

 of the collection was also prepared, and its value much 

 enhanced by the addition of references to the principal notices 

 of economic groups and also of individual species, thus making 

 it practically a reference book to the latest and most accessible 

 accounts of the various pests represented, and, in addition to
