19 4 THE CANADIAN ENTOMOLOGIST, 



Manitoulin Island, also Sault Ste. Marie and the district adjoining. 

 Although prevented by an accident from indulging in free locomotion, still 

 I saw much that interested me. On Manitoulin Island I found many of 

 the species of butterflies common in the more southern portions of 

 Ontario ; a few moths were also captured. On the shore of Elizabeth 

 Bay. near the western extremity of the island, a full-grown larva of 

 Attacus luna was picked up, and on enquiry I learned that earlier in the 

 season that beautiful moth was quite common in that neighborhood. 



In the department of Economic Entomology some items of interest 

 were gleaned. The pea crop throughout this district is an important one, 

 and I made a diligent search in many fields for indications of the presence 

 of the pea bug, Bntehus pisi, but could find no traces of it. Satisfactory 

 evidence Was furnished me in at least two instances of the sowing of seed 

 brought into the island which was badly infested by this weevil, yet I was 

 assured that neither during the season following nor in subsequent seasons 

 did the crop suffer from this pest. The pea crops growing in these par- 

 ticular localities were also examined by me. Hence it would appear that 

 the climatic or other conditions prevailing in this district are so unfavor- 

 able to this destructive pest that it is unable to survive. Should this 

 exemption prove permanent, the cultivation of the pea there will doubt- 

 less be rapidly extended, as there will be a large demand at good prices 

 for seed peas from this section, since so many portions of the Province 

 are now so overrun with the pea bug that it is difficult to get seed fit for 

 sowing; and, for the same reason such seed peas will be readily purchased 

 for planting in the Western States. 



For many years the district extending from Goderich to Collingwood 

 has, in consequence of its exemption from curculio, been extremely favor- 

 able for plum culture, and here immense quantities have been grown and 

 shipped to other parts of Canada and the United States, Goderich being 

 for many years an important centre for the production and shipment of 

 this fine fruit ; but within a brief period this foe has invaded Goderich in 

 such force that to grow plums successfully there warfare must now be 

 maintained against this pest similar to that practised in the more southern 

 sections of the Province. This enemy has now advanced as far as South- 

 ampton, and before many years we may reasonably expect that the favored 

 district at present exempt from Owen Sound to Collingwood will be 

 similarly invaded. Thinking that the Manitoulin Island, from its insulated 

 position, might possibly offer in the future a fine field for this department
