accuracy of his determinations may be arrived at when I say that such authorities as Dr. 

 Horn and Dr. LeConte, of Philadelphia, after a critical scrutiny of the whole series of Col- 

 eoptera, filling some twenty-seven cases in all, could only detect two or three errors, and 

 these among the smaller and least conspicuous specimens ; such results reflect great credit 

 on the labours of our esteemed coadjutor. In the arrangement of the other departments, 

 your President was ably aided by several gentlemen, notably Messrs. E. B. Reed, J. M. 

 Denton and G. Geddes, of London ; indeed, all our London members were ever ready to 

 render all the assistance in their power. 



The expenses necessarily attendant on this work have been considerable. The making 

 and lining of suitable cases in which to display the insects, the printing of labels, &c., and 

 the numberless outlays entailed by the transmission of specimens to and fro from all parts 

 of the country, as well as many other incidentals which it is needless to enumerate here, 

 combined, have involved a large outlay. This has been chiefly met by a special grant of 

 five hundred dollars from the Government of Ontario, the remainder being drawn from 

 the Society's resources. 



To make the collection as perfect as possible, as far as accurate naming is concerned, 

 the doubtful specimens in the orders most largely represented were submitted to the ex- 

 amination and correction of specialists. The entire collection of Lepidoptera was carefully 

 gone over by Prof A. R. Grote, of Bufi"alo, who generously placed his services at the dis- 

 posal of the Society for this purpose, and twice visited London in order to complete the 

 work. Dr. Horn also kindly rendered all possible aid in the determination of such Col- 

 eoptera as were sumbitted to him, and to Dr. A. S. Packard we are indebted for naming 

 some of the Geometridse. 



The collection arrived safely and in good condition in Philadelphia, where it at once 

 attracted much attention. The whole display consisted of eighty sir glass cases, forty- 

 five of which were filled with Lepidoptera, twenty-seven with Coleoptera, and the remain- 

 ing fourteen occupied by the other orders, the whole arranged in a double row on a suitable 

 stand seventy-six feet in length, in the Canadian Department in Agricultural Hall. 



There were no other collections on exhibition in Philadelphia which would compare 

 favourably with that sent by our Society. There was a very good one in the United 

 States Government Building, from the Department of Agriculture in Washington, arranged 

 by Prof Townend Glover ; this, however, consisted chiefly of Lepidoptera. 



There was a small collection shown in the Canadian Department, adjoining that of 

 our Society, consisting of four or five cases, containing Canadian insects, representing the 

 various orders ; they came, I believe, from Montreal, but I did not succeed in finding the 

 name of tlie party to whom they belonged. Through the neglect or carelessness of our 

 Canadian Commission, neither this collection nor that of our own Society are mentioned 

 in tlie official catalogue, do not appear to have been entered as belonging to any depart- 

 ment of the exhibition, and hence were not examined at all by the Centennial judges. 

 Had it been otherwise, we should no doubt have been honoured with awards which, in 

 the case of our Society, if we may judge from the laudatory comments of those best able 

 to form an o])inion, were well deserved. 



In the Kansas State Building there was a collection from the State Board of Agri- 

 culture, arranged by Prof Snow, consisting of thirty cases : sixteen of Lepidoptera (seven 

 of butterflies and nine of moths), five of Coleoptera, two Neuroptera, two Orthoptera, 

 three Hymenoptera, one Diptera, and one Hemiptera. Theso were very well set up, 

 classified, and nearly all named, and wore very creditable to Prof. Snow and the Board by 

 whom they were sent. There was, nevertheless, one drawback to viewing them with any 

 satisfaction : the dust was allowed to accumulate on the glasses to such an extent as to 

 obscure the objects contained. 



There was a collection from Brazil, shown in the Brazilian Department in the Main 

 Building. This, we were told, was the work and property of a private gentleman residing 

 in Rio Janeiro ; it was arranged in thirty-five cases, thirty-one of wliich were Coleoptera 

 and four Lepidoptera. This collection was very much mixed ; there was no attempt 

 made to name the insects, except to the extent of partially indicating the family names. 

 Neither was there much effort towards a correct classification ; they seemed to be partly 

 arranged with regard to their natural relationship and partly with the view of display. 

 Among the butterflies and moths there were some superb specimens whose brilliance at-
