The species' in the reiriaining two sub-families have proved 

 more numerous than I anticipated. Fortunately I was able to 

 send about a score of the more difficult specimens to Mr. Ash- 

 mead, who found among them seven new species, including re- 

 presentatives of two new genera. He very kindly prepared , for 

 me descriptions of these new genera and species, which wiir be 

 found in the Canadian Entomologist, Vol. XXIX, pp. 53, 56. 

 The first Hst contained 99 species and in the subjoined one are 

 60, so that, after allowing for possible synonyms, we have, in 

 ' round numbers, 1 50 species captured in this locality. All the 

 sub-families are represented except the second--Embolinae^pf 

 which, however, only one American species has been recognized, 

 viz. Ampulicoviorpha confusa, Ashm., from California and Nevada. 

 Undoubtedly many other species will yet be found around us, 

 perhaps enough to swell this preliminary list to 200 eventually. 

 New localities will have to be visited, as those which were 

 nearest are rapidly disappearing. Since the first portion of this 

 paper was printed, Powell's Grove and the Race-course have met 

 the fate of the luxuriant woods which, a ^&\n years ago, were 

 known as Stewart's bush — the happy hunting grounds of the 

 botanist, and yielding some game even, for the gunner. The 

 fall of the giant twin-pine that stood on Bank Street, signalled 

 the near clearance of the adjacent woodland patches to make 

 way for the extension of the city southward. Both Powell's 

 Grove and the swamp enclosed by the old race track wSre 

 capital collecting grounds, and their disappearance, albeit
