184: THE CANADIAN ENTOMOLOGIST. 
by the Standing Committee to the effect that the formation of a Sub- 
section of Entomology in Section B be authorised by the Association, and. 
the necessary amendment to the Constitution be brought up for adoption 
at the next annual meeting. This recommendation was unanimously 
adopted by the meeting, and will no doubt be ratified next year; we may, 
therefore, look upon the “‘Sub-section of Entomology” as an accomplished 
fact. We trust that our readers will now do what in them lies to make it 
a useful and attractive portion of the Association, and not allow so good 
a vantage ground to be lost by apathy and indifference. We would 
venture to suggest to the Committee that they should, at an early date, 
announce some special department of entomology to be taken up by the 
meeting next year, in addition to any subjects that may be brought into 
discussion by the papers of individual members. Such a plan, though 
not perhaps quite in accordance with precedent, would, we think, add 
value and attractiveness to the meeting, and poss ae bring together more 
of our “brethren of the net” than usually attend on such occasions. 
The proceedings of Monday brought the actual work of the meeting © 
pretty well to a close; few of the members, however, returned to their 
homes without first going upon one or more of the interesting excursions 
that were made to various localities in the neighbourhood. ‘These, we 
eel sure, were Ne enjoyed by all who took part in them, even though 
some—like the writer—may not be able to avoid occasional painful 
reminiscences of a crawl through a lead-mine, or a night among the 
Sioux City mosquitoes. 
The next meeting is to be held on the shores of the’ Atlantic at Port 
land, Maine, and will, we trust, prove as agreeable a reunion as the one 
lately brought to a close on the far away banks of the Mississippi. 
ON THE GEOGRAPHICAL DISTRIBUTION OF SOME 
GENERA OF CANADIAN INSECTS. 
BY FRANCIS WALKER, F.L.S., LONDON, ENGLAND. ; 
° 
The study of the geographical distribution of Insects acquires addi- 
tional interest by its connection with astronomical calculations, and with 
geological researches. From them it is understood that the earth was 
once covered with snow and ice from the poles to the tropics, and that 
the like event may recur in the future, and restore the hemispheres
