POTATO BEETLE. 



Prof. J. T. Bell, of Belleville, remarked that he had found the Potato Beetle feeding in 

 his neighbourhood on the "Bittersweet," Solanum dulcamara. 



Mr. Saunders stated that during his recent visit to Colorado, although he travelled 

 much over the plains and through the mountain canons, he found no traces of this insect 

 in any of its stages. 



Mr. Chas. Arnold, of Paris, said that in his section the Colorado Beetle, after having 

 devoured the potato vines, attacked the tomato plants. 



Mr. P. C. Dempsey, of Trenton, stated that he had preserved his tomato vines from 

 injury by the beetle by the free use of Paris Green on his potato plants. 



Mr. J. A. Moffat, of Hamilton, stated that he had observed serious injury to ]je 

 caused to the young plants by the beetle. 



Mr. Saunders reported that Lehia grandis, one of the beneficial insects which devour 

 the larvie of the Colorado Beetle, had been found by him in greater numbers than usual^ 

 and that he had taken a number of specimens at night while sugaring for moths. Mr. 

 Moffat had also observed it to be common near Hamilton, on the Golden-rod Solidago. 



COTTON WORM. 



Mr. Jas. Fletcher had written to ask if any member had made any observations 

 during the year on the moth of the Cotton Worm, Aletia argillacea, in reference to which 

 an interesting discussion took place at the last annual meeting. 



Mr. Moffat reported having captured several specimens, and Mr. Peed had observed 

 their frequent occurrence, attracted by light in the house at night during September. 



CABBAGE BUTTERFLY. 



Mr. Saunders reported that as far as he could ascertain, the extreme western limit 

 of this insect did not at present exceed 100 miles west of Chicago. 



Prof. Bell stated that he was of opinion that in the neighbourhood of Belleville the 

 common English sparrow had proved useful in destroying the larvae of this butterfly. 



The chairman, Mr. Saunders, remarked that this was contrary to the experience of 

 all those who had made a special study of the habits of this sparrow, and enquired 

 whether the Professor had ever examined the crop of the bird for evidences of the 

 presence of this larva, to which the Professor replied in the negative. 



A RARE BEETLE. 



Prof. Bell exhibited several specimens of Alaus gorgops, one of which he had captured 

 near Belleville ; and showed the peculiar points of difference between this insect and our 

 common Eyed Elater, Alaus occulatus. 



NEW CLOVER INSECT. 



Mr. Wm. Weld, editor of the Farmer's Advocate, said that he had lately read in 

 several American papers accounts of the ravages of a new clover insect ; that specimens of 

 clover heads had recently been sent him by several correspondents, infested with an 

 insect which he believed to be this new species ; and asked whether any of the Entomolo- 

 gists present could give him any information as to where it had occurred, and the amount 

 of damage it was likely to cause in this Province. 



Mr. Arnold thought, from what he had heard from those growing clover in his vici- 

 nity, that this insect was injuring the crop there. Mr. Saunders said that the insect had 

 not yet come under his observation, and that he would be very glad to receive specimens 

 from any person who should find them in this Province. 



The insect referred to is the Clover Midge, Cecidoinyia leguminicola, a small fly which 

 in its larval state devours the ripening seeds in the clover heads.
