pillars burrow as they do in the cotton bolls, and to some people 

 the idea of a large fat grub busily at work within would spoil 

 the taste of the largest and ga)-est tomato. 



Of the many enemies of the fruit grower, one has been so 

 long with us that we almost forget that it is not native to the soil. 

 This is the destructive Codling Moth, Carpocapsa poiuonclla, 

 recognized in America as early as 1819 and whose progeny one 

 often finds snugly domiciled in the rosy-cheeked apple when it 

 is eaten, resulting at times in the biter being bitten. This is by 

 no means an insect new to science as worm}- apples as said to 

 be referred to in literature two thousand }-ears old; when the 

 fruit was presumabh' much less luscious and tempting than it is 

 at present. Indeed we ma}' reasonably assume that the first 

 green apples with which the children of the cave-dwellers shar- 

 pened their teeth, alread}^ harboured the retiring and gentle 



grub. 



Occasionally specimens have been captured in Ottawa of an 

 unusually large and handsome moth named Erebus odora. The 

 occurrence of this fine insect so far north is both remarkable 

 and puzzling, as it is an inhabitant of the West Indies and 

 Central America, and it seems scarce!}' possible that individuals, 

 even aided by favourable winds, could accomplish such long 

 flights without becoming ver}- much travel-worn ; yet the speci- 

 mens observed have been in good condition. 



Of Hymenoptera quite a number of species have come to 

 us ; of which probably the most important is the Honey Bee, 

 Apis niellifica L.,who labours during the hot Canadian summers 

 to increase the sweets of our existence, but whose manifest 

 virtues we will not stop to discuss. There are also several ob- 

 noxious forms belonging to the group known as Saw-flies, which 

 have caterpillar-like larvas. The blushing rose, that universal 

 symbol of beauty and fragrance, among the man\- foes that stale 

 and wither its infinite variet}- numbers three species of saw-flies, 

 all of which, there is good reason to believe, arc from over the 

 ocean. Mortostegia rc'j-f^ Harris has been known in America since
