178 THE CANADIAN ENTOMOLOGIST. 



A tree once attacked never seems to recover, and the only way to 

 check the ravages of the insect is to cut down those trees affected. 



In Montana the cattle feed out all the year round on the " bunch" 

 grass, which is of inestimable value to that country. A curious fact to be 

 noticed is that wherever timothy and blue grass is introduced it seems to 

 kill out the bunch grass, so that the advance of civilization may in fact 

 entirely alter the economy of the country. 



The grasses do not seem troubled as yet with any pests. 



The Colorado potato bug is merely known in certain localities. 



The fruit trees are troubled only by flies and ants, so that the territory 

 is nearly free from noxious pests. 



Prof. Henshaw said the expedition was one of great interest. 



A curious feature was the late hours at which insects appeared to feed, 

 many of them after sundown. 



Papilio machaon was found in great numbers. 



Carabidce were found in dry places, whereas in the East they usually 

 preferred moist situations. 



The genus Callopieryx was also found. This was especially noticeable 

 as it had never been known to occur west of the Rocky Mountains. 



After this a considerable time was spent in informal discussion and ex- 

 amination of interesting specimens brought by members from various parts 

 of the continent, and the meeting then adjourned. 



THE GRAPE BERR Y MOTH—Lobesia botraim. 



BY THE EDITOR. 



This insect is an imported species and has long been injurious to 

 grape culture in the South of Europe. The exact period of its introduc- 

 tion to America is not known, and it is only within the past few years 

 that attention has been called to its ravages. When abundant it is very 

 destructive, in some instances it is said to have destroyed nearly fifty per 

 cent, of the crop. 



During the past season it has been very abundant in the neighborhood 

 of London, there being very few vines the fruit of which has not been 

 more or less injured. The young larvae have usually been first observed
