, ,1,1 But in this case — they are going north, mind — they fly singly. To ajwatching fisherman, 

 IS ;in example gets abreast of his boat, he may look out across the water and see another coming 

 lu about the .same track, and if he strains his eyes a bit, still another, just a speck, can generally 

 be made out, -well up in the blue. And so it goes on through the warmer hours of the day. 

 ArrMppus or Turnus do not mind the flight at all, but poor little Philodice or P. rupee are glad 

 indeed to settle on the first bit of herbage or flower they can reach. So the number which 

 cross this body of water is large, and one rarely sees an example in the water. 



" The most striking emigration in point of numbers that I recall as coming from Long Island 

 was that httle white and black speckled geometer— Caierwf Catenaria, which came over in 

 myriads during one whole day, and gave our landscape quite a snow-squally effect. But these 

 feeble flyers Were dependent on a stiflf breeze for making the trip at all, and then about half of 

 them fell in the water. So much for emigration." 



lu refeience to the point which Mr. Bird has called my attention to: that those separate 

 specimens of Archippns were all flying north when crossing Long Island Sound, I would remark, 

 that in doing so at that time they are as certainly obeying their natural inclination to travel, 

 and that for a purpose, as when they go south in crowds later in the season. For, if those 

 single individuals could have been traced to their destination it would have been found that 

 they were making for a general gathering place, where they were forming one of those immense 

 -warms which have attracted so much attention, preparatory to their leaving in a flock to go 

 -outh together. So the fact of their going north at that time does not conflict with their going 

 •^outh later on, as they have to gather from all directions, at what appears like a preconcerted 

 place of meeting. Constrained by an internal monition, or drawn by some invisible magnetic 

 influence, they gather from every point pi the compass to one particular place, as unerringly as 

 the needle ttyns to the pole, and there await the gathering of the crowd, to start out at the 

 proper time on their long southward journey. As they do not, so it seems that they cannot at 

 that time go singly ; and the belated stragglers that are left behind the migrating flocks in this 

 latitude, assuredly 23etish. 



'Nnmhers of Arch ipjvis butterflies were to be seen flitting about the streets of London, 

 during the first week of September, and occasionally stopping to feed at moist places. The last 

 one observed on the wing was on the 27th of the month. 



About the first of September Mr. Balkwill brought in some beetles that had been found 

 feeding upon green corn insida the husks, with a sample of the injured corn. The beetle 

 proved to be Euphoria inda, Linn. (Fig 32), a well-known injurious flower beetle, 

 also bearing an unsavory reputation for spoiling soft ripe fruits, such as pears, 

 plums and peaches. It was the first time my attention had been drawn to its 

 attacking corn in this country, although it is known as an old offender in that 

 direction in the south-western States. From the appearance of the corn that was 

 presented, it is evident that this beetle is quite capable of doing a vast amount of 

 Fig 32. damage in a cornfield where they are numerous; which, fortunately for Canada, 

 they have not, so far, been found to be. Their ability and method of reaching the corn inside 

 the husks has been a subject of considerable discussion in the localities where their injury has 

 been greatest, some claiming that it is only after the husk has been torn open by bird or beast 

 that the beetles can reach the grain. But from the wonderful strength with which they are 

 endowed, which every one who has handled them must have noticed, one could readily believe 

 that they would have no difticulty whatever in pushing their way inside the husk by the silk 

 end. And. seeing that they bury themselves in the ground to pass the winter, they might 

 easily dig through the husks in order to obtain the succulent morsels within, in the absence of 

 'tlier things within their reach where m to satisfy their cravings.
