when he allowed them to escape. Very many of them, though | 
not all, found their way back to their nests, and as a rule reached 
home sooner than the author did himself. 
The author noticed that at his summer residence, where he had 
kept numerous hives of these bees, the following spring many in- 
dividuals appeared, and seemed to be searching for their previous 
uals of the previous broods or.not. Towards the close of July, 
1884, he obtained three nests of Bombus mastrucatus, a large spe- 
cies only found in the mountains, and especially the higher re- 
gions, and carried them to his residence in the city, where he 
placed them in a window of the second story. The house was en- 
closed by high buildings, with no garden attached, and yet they 
returned readily and directly from their excursions to their nests. 
They throve, and by the first of October had increased to con- 
siderable numbers. By the middle of October they wholly disap- 
peared; but in the early part of the following April, individuals 
of this species were observed flying about the window, and as 
soon as they found an entrance, sought the remains of their old 
“nests, and took up their abode. They remained fora while, when 
their nest was accidentally injured, and they left. Nothing more 
was seen of them till after the author’s return from his summer 
vacation, in the middle of September, when a single female of this 
species made its appearance. In their inability to obtain an en- 
trance through the closed window, they had evidently built a new 
hest in the vicinity, and reared their broods. >
