Aphids in general were kept well in check this year by natural con- 

 trol, and many specie.s of regular economic importance were a negligible 

 quantity, as far as my observations went. The apple-grain aphis was 

 in very small quantity on either host and was heavily parasitized all 

 summer by a small hymenopteron. Coccinellids and Syrphids were abun- 

 dant this year and kept all species in check effectually. 



Amongst insects of general importance, several species of sawfly, 

 especially on roses, Avere more than usually abundant, whilst the opposite 

 extreme was attained by the Red-legged locust (Melanoplus femur- 

 rubrum), whose numbers were very small after a period of abundance 

 for three years. It would be interesting and useful to know the exact 

 causes of these fluctuations. 



THE RELATION OF BOTANY TO ENTOMOLOGY 



By W. B. Anderson, Victoria. 



In offering you these few remarks, I do not purpose going deeply 

 into my subject, nor have I made this paper too long. It is, in a way, 

 a filler-up, as so many of our older members seem to have given up the 

 writing of papers for these meetings, for the entertainment or the instruc- 

 tion of such of us as have had less time or fewer opportunities for syste- 

 matic collecting. This is miich to be deplored, for to the existence of this 

 Society we are indebted to the zealous efforts of the older Provincial 

 Systematists, and it is to be hoped that another year will see more of our 

 old friends, and again hear from them of some of their delightful and 

 entertaining experiences. 



I have taken for title, "The Relation of Botany to Entomology," 

 and propose to show, in so far as I am able, the vahie of a knowledge of 

 Botany to the collector. 



Among Economists, this is being demonstrated every day, in most 

 cases quite unwittingly. As, for example, a searcher for the Codling Moth 

 goes through apple orchards ; for the Leaf Slug, among the cherries and 

 pears. For the Vine Weevil among grapes, strawberries and primulas. 

 So with other pests which harry the soul of the orchardist or the farmer, 

 or gardener. But everyone knows the trees and plants just named, and 

 the average Economist, were he to find any one of the pests enumerated 

 on any other host plant but those he has been accustomed to associate 

 with the particular insect, will be quite at sea, and unable to name the 

 plant without collecting specimens and submitting them to someone of 

 Botanical knowledge.
