mens under the bark of an elm stump, curiously arranged in regular rows ; 

 Mr. Harrington had also observed the same species, and remarked that 

 Drs. Leconte and Horn, in their new Classification of Coleoptera, 

 referred to these curious groups of pupae. 



Mr. Fletcher had found Mamestra picta very abundant at Ottawa on 

 cabbage, carrots, and many wild plants. 



Mr. Harrington remarked that Lycomorpha p/iolus had been very 

 common in the vicinity of Ottawa this season ; he had seen hundreds of 

 them ; had also found (Edipoda corallina, Harris, quite common in oat 

 fields. 



Rev. Mr. Fyles reported the currant worm, Nematus ventricosus, as 

 being very abundant at Levis, P. Q., where the bushes had been almost 

 destroyed by* them. He also stated that much injury had been caused to 

 the tamarack trees, Larix Americana, in Bury and the neighboring town- 

 ships, by a species of Saw fly, probal^ly Nematus Erichsonii, the insect 

 which has caused so much injury to tliis tree in Maine and other Eastern 

 States. 



Mr. Harrington informed the members he had found Xyphidria albi- 

 coniis boring on maples, chiefly on young trees where the bark was thin. 

 He had observed them ovipositing from the middle of June to the end of 

 July. The ovipositor is short. He found in one instance a tree thoroughly 

 riddled by the borers, they having penetrated directly into the wood. 



The members having spent some time in examining interesting insects 

 in the Society's collection, as well as those brought to the meeting ; and 

 also having availed themselves of the opportunity of reference to many of 

 the valuable books in the Society's library, brought to a close a most 

 interesting and profitable session.
