 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 diy earth, at the root of trees. They 

 lived there with other terrestrial larvae, and also with those of a Colymbetes, 

 which appears to have the same habits. On finding these larvae, not doubting 

 but that they. were true terrestrial species, I reared them in the earth. They 

 bved 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 larva? live so long a time
