98 THE CANADIAN ENTOMOLOGIST. 



Noctuidae, found in Boreal America, with critical notes," was prepared by 

 him and appeared in 1893. This is indispensable to students of these 

 insects, as are also his many "Contributions toward a Monograph of the 

 Noctuidce of Boreal America." His best scientific work was undoubtedly 

 in this family, of which he was our leading American authority. It is 

 impossible to mention here the many articles which he published, in 

 revising genera, describing new species (of which he created many 

 hundreds), etc. The first paper he published in The Canadian Entomo- 

 logist appeared in Volume XIV. Since that date he has been one of our 

 most valued contributors. Articles from his pen have been published in 

 24 different volumes of this journal. A bibliography of his systematic papers 

 would fill many pages ; it is to be hoped that such will soon be prepared. 



In 1891, Dr. Smith published a "List of the Lepidoptera of Boreal 

 America/' which was used generally by lepidopterists. This check list 

 was revised and re-published in 1903. "Explanation of Terms Used in 

 Entomology " was prepared by him and appeared in 1906. His "Cata- 

 logue of the Insects of New Jersey," the third edition of which recently 

 appeared, is an extremely useful publication, and the only one of its kind 

 which has been published by any state in the United States. 



Other important works, of a popular nature, written by Dr. Smith, are 

 " Economic Entomology," published in 1896, which is a valuable book 

 fi)r students of entomology, farmers, etc., and "Our Insect Friends and 

 Enemies," which appeared in 1909. This latter treats of insects in 

 relation to man, to other animals, to one another, and to plants, and in it 

 there is also a chapter on the war against insects. 



As an economic entomologist few men in the woild were his equal. 

 His series of annual reports, the first of which was included in the Tenth 

 Annual Report of the New Jersey Agricultural Experiment Station, 1889, 

 and the last, that for 1910, which was published in 1911, together with 

 the many economic bulletins which he prepared, form a valuable source 

 of reference concerning injurious insects, particularly those occurring 

 within the State of New Jersey. The very successful work he did on the 

 control of mosquitoes has been commented upon widely. His special 

 report, published in 1904, 482 pp., up3n the mosquitoes occurring 

 within the State of New Jersey, in which is included an account of the 

 different species, their habits, life-history, economic treatment, etc., is an 

 extremely valuable contribution and shows the remarkable capability of 

 the man in dealing with problems of such magnitude. Further accounts 

 of this mosqu'to work are given at considerable length in his annual 

 reports, since the above dates.
