Means of Education." The evening was tiioroughly enjoyed by all present, 

 and no doubt the school teachers carried away with them much information 

 and many impressions that will be of value to them in the future. 



The next day, July 5th, was given up to an excursion to Puslinch 

 Lake, a picturesque sheet of water about nine miles from the College. 

 The Summer School joined in the picnic, making up a party of more than 

 sixty in all. The day was spent in collecting botanical and entomological 

 specimens and other objects of interest. At the close short addresses 

 were given by members of the College staff and others on various 

 specimens that had been brought in, including fresh-water shells, insects 

 and plants. The meeting on the whole was so delightful and successful 

 an experiment that it will no doubt be repeated in future years, and 

 become annually more attractive and well attended. 



At a meeting of the Council, Mr. L. Caesar, O. A. College, was elected 

 Secretary of the Society for the remainder of the year in place of Mr. E. 

 J. Zavitz, who has found it necessary to resign, as his various duties in the 

 department of Forestry leave him no time to devote to the business of the 

 Society.

It would be supposed that the last word had been written about the 

 canker-worms, the literature of which has been so confused, as well as the 

 two species. Had attention been given but slightly to their structural 

 characters, there had been no need of thi^. Pometaria^ Har., is correctly 

 placed, in my judgment, by Dr. Hulst in Ahophila, with cescularia, 

 Schiff, as its type. He says (Trans. Am. Ent. Soc, Vol. 23, p. 258), "I 

 cannot agree with Mr. Meyrick in his reference of this genus to the 

 MonocteniirjB. The most characteristic venation is the merging of vein 

 8 of hind wings with the cell. If this is to be ignored, the lack of the 

 accessory cell would be no more reason why it should be placed with the 

 MonocteniinDS than with the Ennominae." He might have gone further, 

 for besides the merging of vein 8 with cell, vein 5 is present, and this 

 effectually keeps it out of the Ennominse, besides, it has an accessory cell, 

 as has also the type. Hence the reasons disappear why it should not 

 stand just where it does. 



With Paleacrita the strange part of the present arrangement comes 

 in. Here the type vernaia, Peck., has the true venation of the Ennominae,
