 August, 1884. 



Herbert Osborn presented a paper on the "Food Habits of the 

 ThnpidiP. "* 



Mr. Smith remarked that he considered the habits of the group as 

 very important economically and hoped additional information could be 

 stated here. 



Mr. Howard mentioned the supposed occurence in Europe, in 

 Phylloxera Galls, of the species called Thrips phylloxercz by Prof Rile}-. 



Mr, Webster stated that he had kept a species of Thrips for several 

 weeks on wheat without other nutriment. 



Mr. Fletcher mentioned the injury done on exhausted meadow 

 lands in Canada to June Grass {Poa pratensis) and to Timothy {Phleufn 

 pratense) which was apparently due to Thrips. 



Mr. Howard had seen the species mentioned by Prof Comstock 

 and had known cases where every stalk of grass showing injury would 

 be found on examination to contain Thrips. 



Mr. Smith said he had observed Thripidcs in galls but had not con- 

 considered them as the authors of the galls or as feeding upon the larvae. 



Mr. Smith asked IMr. Westcott for information concerning Illinois 

 collections. 



Mr. Westcott remarked that there were a few good collections in 

 Illinois and invited the President and others to examine them in person. 



Mr. Smith remarked upon the collection of Mr. Bruce, especially 

 commending the rich series in certain species which were represented by 

 such number of specimens that the lines of variation could be very 

 clearly followed. 



Adjourned to meet the following morning. 



Friday Morning. — Club met at nine o'clock, and the reading of the 

 minutes having been deferred, the Club listened to a paper by Mr. D. S. 

 Kellicott on Hepialus argentiomaculata.
