fast being devoured. Lupins seemed to be the favorite and not 

 one was left. The beetles seemed to be drunk with the nectar for 

 they stuck to the flowers and we could easily cut the stock and drop 

 it in a pail of kerosene. We caught hundreds in this way. Later, 

 in the afternoon, they seemed to have taken flight. There was a 

 flight of about 300 on June 12, eating lupin, roses, syringas, iris, etc., 

 eating the flowers and not the foliage. They appeared suddenly, 

 over night. There was no special wind or other climatic conditions 

 noticed. They were exterminated by hand and after a heavy rain 

 at night none appeared next day." 



The other Stockbridge correspondent, on June 23, wrote: ''Three 

 days ago I found these beetles eating the roses in the garden. They 

 lighted, half a dozen or so, on one rose and devoured it rapidly. They 

 were either so sluggish or so hungry that they were easily caught and 

 the gardener drowned several hundred in an hour. Since then I 

 have seen only a few scattered individuals. They seem tenacious of 

 life, as specimens have lived three days in a box. 



During the last ten years it has been of interest to note that the 

 insects named by the New York State Entomologist in any year as 

 attracting attention, were also as a rule, those receiving similar 

 attention in the Connecticut report of that year, and it was usually 

 safe to expect their presence in Massachusetts the following year. 

 It would almost seem as though most of these cases of increase in 

 abundance originated to the west, and reached Massachusetts from 

 that direction. This has sometimes been so marked that the western 

 end of the state would show an unusual abundance of some pest which 

 the following year extended its injuries into the eastern end of the state. 



The above is of course, only a generalization, but it has never- 

 theless occurred so often as to attract some attention. 



INJURIOUS INSECTS OF 191 1 AT TREESBANK, MANITOBA 



By Norman Criddle 



The" season of 1911 had few surprises for the economic Entomologist 

 and the injury done to crops and other vegetation was chiefly due to 

 the continuous, or increased abundance of insects commonly met with 

 the previous year. The most important of these are depicted in the 

 following notes. 



Insects Injurious to Grain and Grasses 



Hessian Fly, Mayetiola destructor. — Infested spring wheat plants 

 were gathered on May 17, being injured chiefly below the ground. 

 The larvse at this time were small and difficult to detect. On June
