204 THE CANADIAN ENTOMOLOGIST. 



on Popuhis alba, the latter known as the Silver Abele tree ; the larvae varied 

 very much in coloration. Hitherto this insect has been supposed to feed 

 only on apple, plum, and wild cherry. 



Mr. Saunders stated that he had found the larvae of Papilio turniis this 

 season on a new food plant, Magnolia accuininata. As many as forty or 

 fifty specimens were found on a single tree ; they varied in size from the 

 newly hatched to the full grown larva, all feeding together ; eggs were also 

 found at the same time and place. 



Mr. Fletcher reported finding the larva of Darapsa versicolor feeding 

 on swamp loosestrife, JVesoea verticillata. He had bred a single specimen 

 two years in succession. It is curious to note that this plant grows in the 

 water, and being herbaceous, decays and becomes submerged during the 

 autumn and winter months. In these instances there was no favorable 

 pupating place nearer than the shore, so that the larva would have to swim 

 ashore, unless it formed its cocoon among the leaves and these drifted to 

 land. 



Mr. Reed exhibited and reported the larvse of Notodonta albifrotis, 

 Sni. and Ab^, as common in London on the maple ; he had also observed 

 them recently on the elms in Toronto and Montreal. Other members had 

 found them generally common this season on the oak. 



Mr. Saunders had found the larvae of Papilio cresphontes on the wafer 

 ash, Ptelea trifoliata ; also on the prickly ash, Zanthoxyliim Aj?ierica?ium. 

 At this late period of the year (September) the larvae may be found quite 

 small. Query. — Do these perish from early frost ? If not, how do they 

 pass the winter ? 



The meeting then adjourned, to meet next morning at 9.30 a. m. 



Thursday Morning, October 4. 



The meeting opened ai the Society's rooms at 9.30. 



The question of the use of Paris green for the codling worm of the 

 apple, Carpocapsa po/iionella, was discussed, and while the members con- 

 curred in the desirability of testing this remedy very fully, they recom- 

 mended that due caution should be used in preparing the mixture, not to 

 make it too strong, one teaspoonful of the poison to a pailful of Avater 

 being sufficient ; if used much stronger than this it is apt to injure the 

 foliage. 



An interesting communication was read from Mr. J. Alston Moffat, of 

 Hamilton, on the pupa of Calopteron reticulatum. ^ He has found speci-
