Many other large groups have also been almost entirely neglected, 

 and will yield, when properly investigated, oiany additional species. If 

 there were a few more collectors the different localities could he 

 properly examined, and the list of Ottawa species carried within a year 

 or two to probably fifteen hundred, and eventually to fully two 

 thousand. 



Uutil more of my species are determined it would be almost 

 useless to make any general comparison of our fauna with that of other 

 districts, but I have tabulated three families in which the species are 

 fully determined, with the following results. Of elateridas we have 

 more species than are enumerated in any of the ])reviously mentioned 

 lists, with the exception of the Quebec one, which has an equal number, 

 viz., 89. The others have respectively, Grimsby 77, Lake Superior 82, 

 Michiga:i bO, Buffalo 74, and Florida 52. Of the latter species only 

 nine, or seventeen per cent., have occurred here. Three of these (Alans 

 oeculatus, A. myojjs and Melanotus communis ) are common to all the 

 lists, while one (Fornax hadius) is unrecorded in any of the others. 

 Of Grimsby species we have 51, Lake Superior 51, IMichigan 48, 

 Buffalo 48, and Quebec 58, or sixty-five per cent. That our fauna is 

 essentially a northern one is shown not only by the absence of the 

 Florida species, but from the fact that of 40 species contained in a list 

 of Green Mountain coleoptera (R. Hay ward and H. Savage, Quart. 

 Journal Boston Zoological Soc.) we have 29, or seventy-five per cent. 



In buprestidfe the species enumerated are as follows : Ottawa 37, 

 Grimsby 35, Lake Superior 30, Michigan (which alone exceeds Ottawa) 

 ■38, Quebec 28, Buffalo 34, and Florida 29. From the Green Moun- 

 tains seven species are given, of which we have all. Of the species 

 from the former localities we have from sixty to sixty-five per cent., ex- 

 cept of the Florida species, only seven of which, or about twenty-four 

 per cent., occur here. Of these seven species two are the common 

 injurious insects kno\vn as the apple tree borer (Chrysohothris femorata) 

 and the raspberry borer (Agrilus rujicollisj. 



Of cerambycidfe there are in the Ottawa list 106 species, Grimsby 

 103, Lake Superior 78, Michigan 86, Bufftilo 138, Quebec 111, and 

 Florida 76. We have 60 per cent, of Buffalo species, 63 per cent, of 

 Grimsby, 65 per cent, of Quebec, 68 per cent, of Michigan, and 73 per
