Of Sialis two species are described one of them for the first time, and illus- 
trated by good figures. The larva is aquatic, but the pupa is terrestrial an 
anomalous fact first observed by Roesel, and confirmed by Pictet. But, says 
Pictet, I have been much astonished to find, in spring, these larvae at from six 
to eight feet from the water buried in a very dry earth, at the root of trees. They 
lived there with other terrestrial larva?, and also with those of a Colymbetes, 
which appears to have the same habits. On finding these larvee, not doubting 
but that they were true terrestrial species, I reared them in the earth. They 
lived at least fifteen days before their metamorphosis, and did not seem to have 
been injured. This fact, which is interesting as a trait in the economy of the 
genus, is important in the history of respiration. It is indeed the first instance 
of insects with external respiratory appendages breathing the atmosphere. The 
structure of .these appendages is usually such, that they can fulfil their functions 
only when in a moist condition ; if left dry they shrivel and become useless. I 
had reason, therefore to be astonished when I saw such larvae live so long a time 
uninjured in a very dry soil BRANDT, Remarques sur les nerfs stomato-gas-
