were placed for safe keeping in the furnace room of a small green- 
house, the doors and windows of which were kept closed to prevent 
the escape of the insects. One afternoon in the month of June, 1 
observed a strange insect fluttering about the greenhouse, which 
it soon entered through a ventilator, where I captured it, and 
found it to be a male of the above mentioned species, an insect 
which, until then, I had never seen. During the afternoon, when 
upon another part of the farm, 1 saw another specimen, also a 
male, flying high and directing his course straight for the green- 
house. I was struck with the coincidence of seeing two of these 
insects in the same afternoon, but was fairly astonished upon en- 
_ tering the greenhouse in the evening to find some half a dozen of 
them, all males, sitting about upon various parts of the building, and 
apparently patiently waiting. They were all immediately killed 
and pinned. The next morning, when I entered the furnace room, 
I found that during the night one of my cocoons had produced a 
splendid female moth. Did those males come upon an errand of 
love? If so, by what sense were they guided to the right spot, a 
place entirely unlike the natural haunts of the insect? 
During the past winter in riding about the country I collected 
Several cocoons of this moth for the benefit of a young naturalist 
friend of mine, but retained one, which I hung upon the wall of 
my Office. í 
On the morning of June 21st, a fine female moth came out and 
was the object of considerable interest to the occupants of the 
room. During the day I related the’ above incident to a gentle- 
man and at the same time described the appearance of the male 
insect. I had occasion to be absent from the room a short time 
during the afternoon, and upon my return was told that a male 
= moth had been there and fluttered in and out at the open window 
= Several times, but had finally disappeared. The next day was 
Sunday and the office was closed, but on Monday afternoon a 
“Tale again made his appearance at the office window, came in, 
and after fluttering about the room for a space of ten or fifteen 
Minutes, found the object of his search, and the connection was 
Consummated before our very eyes. Let it be remembered that the 
Office is situated upon the principal business street, in the centre 
of the city, and from half a mile to a mile from any place where 
Such an insect would naturally be found. A friend who has a 
Store some half a mile from my office upon the same street, has
