THE CANADIAN NATUHALIST. 
it does in spring from stumps of the trees felled during win- 
ter. This showed, what I was not previously aware of, that 
there is an ascent of sap in autumn as well as in spring. 
The weather was very similar to that considered favourable 
to the flowing of the sap in spring, — slight frosts at night and 
pleasant warm days. But I was going to allude to another 
curious circumstance : this stump was thronged day after 
day by great numbers of insects^, busily engaged in sucking 
the saccharine juices which exuded. Besides beetles^ bugs, 
ichneumons, and multitudes of flies, of various kinds, there 
were many Noctum and butterflies (chiefly of the Camber- 
well Beauty and Violet-tip species ; the former of which was 
quite numerous). 
F, — l observed the larvae of the firefly shining in the 
grass as late as the evening of the 22nd of October. It may 
be possible we have more than one luminous species of Lam- 
pyris : this is a subject worth some examination. Perhaps, 
what I have supposed to be larv^, may be an apterous spe- 
cies, allied to the glow-worm of Europe. Mr. Knapp, in his 
Journal of a Naturalist, mentions the appearance of the 
glow-worm about the end of September, as unusually late ; 
and that in the mild climate of England. It is true our 
brief return of summery weather may have re-vivified these 
beetles, so far as to induce them to emerge from their hyher- 
nacula, as well as the butterflies and dragonflies, which have 
lately appeared : the last,, especially, seem as exclusively 
summer insects as the fireflies. 
C. — ^ I observed a winged Aphis in the house a few days 
ago : and the crinking of the Grylli has not yet ceased, for I 
have heard it at intervals, since we have been abroad to-day. 
I have within a few days met with several groups of a very 
beautiful little Carabus ( Agonum Cupripenne ) ; at first 
sight you would hardly know it from the polished brown 
sort that runs so swiftly among gardens, which, from their
