REVIEW. 
two pairs, an upper and an under, possessed by them in 
common witli all other well-conducted members of the 
liymenopterous family. So, too, there is a certain curious 
American insect, belonging to the very unsavoury tribe which 
supplies London lodging-houses with one of their most familiar 
entomological specimens ; and this cleverly disguised little 
creature is banded and striped in every part exactly like a 
local hornet, for whom it evidently wishes itself to be 
mistaken. If you were travelling in the wilder parts of 
Colorado you would find a close resemblance to Buffalo Bill 
was no mean personal protection. Hornets, in fact, are 
insects to which birds and other insectivorous animals prefer 
to give a very wide berth, and the reason why they should be 
imitated by a defenceless beetle must be obvious to the 
intelligent student.— From, the “ Cornhill Magazine ” for

Catalogue of Canadian Plants. Parts I., II., and III. ; Polypetalce, 
Gaviopetahe, and Apetalce. By John Macoun, M.A., F.L.S., F.R.S.C. 
Dawson Bro., Montreal. Royal 8vo., pp. 623. 
This important work, which is one of the publications of the Geological 
Survey of Canada, reflects the greatest credit upon the author, and no 
commendation can be more than sufficient for the admirable way in 
which the work has been compiled. Although the modest title of 
“ Catalogue ” is affixed to this work it is in fact a Flora, and a very 
valuable Flora, of that vast region, the Dominion of Canada, including 
also Newfoundland ; and in the present Volume I. we have a full record, 
so far as this is known, of the botany of Canada from Ranunculacese 
to the end of the Exogens. The second volume, which is in a fairly 
complete form, will also consist of three parts. Part I. will contain all 
the Endogens ; Part II., the Anophytes and Acrogens ; Part III., 
the Tliallogens. 
The purpose of this work is to place in the hands of Canadian 
botanists, in a connected form, a full record of all that is known of the 
number and distribution of Canadian plants. That much and 
valuable work has been done is evidenced by the fact that although the 
present volume includes the Exogens only, 2,207 species belonging to 
584 genera have been recorded, and their distribution traced more or 
less fully from Newfoundland to Vancouver Island. 
In compiling this volume Professor Macoun has availed himself of 
all published records, such as Sir William Jackson Hooker’s great work, 
the “Flora Boreali-Americana,” which contained the records of the 
work of the early travellers and explorers ; and also the splendid “ Flora 
of North America,” by Torrey and Gray, the first volume of which 
appeared in 1840, and the last published volume, which completes the 
Gamopetalse, in 1878. In addition to these is the long experience of 
more than a quarter of a century of Professor Macoun, whose observa¬ 
tions in the held extend from the eastern provinces to the Pacific, and
