ENTOMOLOGICAL SOCIETY. 



important contribution which has yet been made to our knowledge of this wonderful and 

 interesting insect. 



Last winter, the Legislature of Massachusetts appropriated $200,000.00, the full 

 amount asked for, to continue the work of exterminating the Gypsy Moth, and as * con- 

 sequence very remarkable progress has been made in this work during the past season, 

 and it now seems probable that if similarly liberal appropriations are continued for sev- 

 eral years longer this important, but tedious, work will bs crowned with success. The 

 work of destroying the Brown-tail Moth has also been intrusted to the same force and is 

 being carried on in connection with the Gypsy Moth work. 



Other work in Economic Entomology which may be referred to is the progress made 

 by the Division of Entomology at Washington in the accumulation of data concerning 

 the distribution of injurious insects in the United States. 



Mr. Pergande, in furtherance of his investigations of the Lecanium scales affecting 

 the fruit trees, spent the summer in Europe and collected large material. 



In the early spring, Dr. Howard visited Mexico to investigate the possibilities of 

 preventing the introduction of the Morelos Orange Fruit Worm into California. 



Mr. It. A. Cooley, an assistant to Prof. Fernald, has beer, at work upon the genus 

 Chionaspis and has accumulated an enormous amount of manerial, and it is anticipated 

 that his paper, when published, will give more than twice the number of species formerly 

 known.

But while the economic side of the science is that which is of chief interest and 

 importance to the conmunity, I confess that my own interests lie rather in the direction 

 of the purely scientific side of the subject. 



**?j$From this point of view the experiments of Mr. Henry E Cramp ton, Jr., of the 

 Department of ZDology of Columbia University, are of surpassing interest. 

 [r— ^Mr. Crampton, following up the experiments of Mr. G. Born upon frog and toad 

 embryos, determined to try similar experiments in grafting upon Lepidoptera in the pupal 

 period and has obtained some traly marvellous results Mr. Crampton selected the pupae 

 of the large Saturnians, Cynthia, Cecropia, Promethea and Polyphemus as being the most 

 suitable, though he also experimented with success upon Vanessa Antiopa, but had no 

 success in his operations upon Danais Archippus.
