 Experiment Station. 



As a systematic entomologist he is known, throughout the 

 world for his work on the Microlepidoptera, particularly on 

 the Tortricids and Pyralids. His published work on the Tor- 

 tricidae includes "A synonymical Catalogue of the described 

 Tortricidae of North America, north of Mexico" (1882), "The 

 Genera of the Tortricidae and their Types" (1908) and many 

 short papers, of which the earliest appeared in the Canadian 

 Entomologist in 1878. His early work on the Tortricidae of 

 North America was the first attempt to bring order out of the 

 chaos resulting from inadequate descriptions, often made from 

 poorly preserved material, incorrect generic determinations and 

 the confusion in nomenclature existing in this group at that 

 time. In any critical estimate of the scientific value of the 

 published results of his studies, as given in the Synonymical 

 Catalogue and in later shorter papers and lists, it must be borne 

 in mind that his was a pioneer work. The correctness of his 

 conceptions of the genera and the care with which the species 

 were examined is perhaps best attested by the fact that apart 

 from changes due to modification in ideas of the limits of 

 genera and changes resulting from the application of the law 

 of priority after more critical study of the work of the early 

 authors, the synonomy and generic position of most of the 

 species is not different from that determined by Fernald. 'The 

 Genera of the Tortricidae and their Types," published in 1908, 

 was the result of painstaking investigation undertaken for the 

 purpose of establishing a stable nomenclature based upon prior- 

 ity and correct conceptions of the genera as determined from 

 their types. The great merit of the work lies in the trust- 

 worthiness of the references, the unprejudiced presentation of 

 the evidence and the critical analysis of the facts. Some 

 workers may not accept all of his conclusions, for reasons 

 among which are -the non-acceptance of Hiibner's "Tentamen" 

 names, an unwillingness to accept accidental fixation of types 

 by Stephen's use, and differences of opinion as 'to the amount
