53 THE EEPOKT OF THE No. 36 



Mr. Gibson: We have a specimen in the collection which may possibly be 

 this species and which is from Brockville. We have not, however, examined it 

 carefully enough to be certain. I was glad to hear of the eastern occurrence of 

 the Hop Elea-beetle, which Mr, DuPorte referred to. 



Prof. Lochhead: I would like to remark in regard to Mr. DuPorte's papers 

 that I had not much time to give to the work done by Mr. DuPorte, who is a 

 member of the Biology staff of Macdonald College as investigator under the 

 Dominion Federal Agricultural Institution Act. He has done a great deal of 

 work of which this is a small fraction, and he has other more elaborate work at 

 hand. It is especially in the line of anatomical work that his investigations are 

 valuable. I know of no person in Canada who is more adept or more patient in 

 the unravelling of minute anatomy than Mr. DuPorte, and we may expect to 

 hear of some of his investigations a little later. He had the honour of presenting 

 a paper to the Koyal Society last year, and I feel sure that Mr. DuPorte will 

 favor us year after year with his attendance and give an account of his work. 



The President: If there is no further discussion I think we will conclude 

 this morning's session. 



THUESDAY, NOVEMBER 4th— AFTERNOON" SESSION. 



The President: We are to begin the afternoon session with a paper by 

 Dr. Fyles. Dr. Fyles needs no introduction to the Entomological Society. He 

 is the oldest member among us, and when he said last year that the paper he 

 presented would be probably the last I well remember disputing the fact with 

 him, and apparently my own prophecy has proved correct in that we are to 

 enjoy another paper by Dr. Fyles entitled " Observations Upon Some of tlie 

 Predaceous and Parasitic Hymenoptera." 



OBSERVATIONS UPON SOME OF THE PREDACEOUS AND PARASITIC 



HYMENOPTERA. 



Rev. Dr. Fyles, Ottaw^a. 



One day in summer, I was sitting under the verandah of a friend's house, 

 at Hull, when I noticed a specimen of Pelopceus cementarius Drury, exploring 

 some webs that had escaped the notice of the mistress of the dwelling. The 

 creature was in search of spiders, wherewith to provision the mud castles that 

 it was building for its young. This incident suggested the subject of my paper. 



The question entered my mind. How can I obtain a supply of the mud 

 structures for use in the preparation of the article? I bethought me that boys 

 are privileged, and can go where older persons cannot, without being regarded 

 as intruders, so I asked the aid of one of Baden Powell's hoy scouts, and not 

 in vain; for next day he obtained for me an ample supply of the castles, from 

 an unused attic of a neighboring house. 



Pelopceus cementarius has practised the business of pottery from the creation 

 of the world that now is. Its instinct impels and guides it, and its work is 

 accurately done, according to its need. 



I have watched the insect preparing material for its building.
