THE WEEKLY ENTOMOLOGIST;

And now I come to tlie most singu- 
lar fact of all. When the larva were 
getting matured I took a journey one 
morning from Bowdon for the sole 
purpose of procuring a supply of soil, 
from the roots of the trees from which 
I had taken the imago in spring. A 
large bag of it which I procured, 
however, not proving sufficient, I 
placed a batch of larva in a flower 
pot, with their own soil ; and not 
feeling any fear of coming disaster, 
or any inclination to perform my 
travels again, I consigned the remain- 
der of the larva, to some soil out of 
my own garden. 
Extraordinary as it may seem, and 
I have no doubt that some will read 
the fact with incredulity, the conse- 
quence was that, all the larva which 
were transplanted to a foreign soil, 
with one noble exception, refused to 
enter the pupa state, and obstinately 
perished on the surface of the earth. 
On the other hand, the larger batch, 
finding themselves at home, went 
through the usual stage of transition, 
and, without a single exception, be- 
came pupa. This fact appears to 
reveal a new mystery in the world of 
> nature ; and open a new subject to 
enquiry. — J. B. Blackbuiix.
