208 The Ottawa Naturalist. [Jan. 



given. To Canadian students of insects, his untimely death is 

 a terrible blow, and entomology generally has lost one of its 

 most accomplished exponents. Early in life Dr. Fletcher had a 

 keen love for insects and their ways, and before he came to 

 Canada he was familiar with the butterflies and other insects 

 of his native land. He made a special study, however, of 

 those kinds which are injurious or beneficial, and never lost an 

 opportunity to add to his knowledge of these creatures, which 

 play such an important part in the welfare of mankind. Not a 

 few Canadians have done splendid work in entomology, from 

 the continued encouragement and help which they received 

 from him. 



From a purely scientific standpoint Dr. Fletcher did splendid 

 work among the diurnal lepidoptera. For many years he was 

 intensely interested in Canadian butterflies and through his 

 studies was recognised as a high authority on these insects by 

 American entomologists. He was not only a student of the per- 

 fect forms of butterflies, but was deeply concerned in finding out 

 their true life-histories. Many a long trip from Ottawa was 

 taken by him to get the eggs of a rare species, in order that the 

 various stages of the insect might be studied. During these col- 

 lecting trips, too, many new species were discovered. If we glance 

 through the lists of North American insects, we find that quite 

 a number of species were named in his honour. The following is 

 a list of the insects to which the name of Fletcher has been 

 given : —
