Galli Valerio and J. R. De Jong have continued their studies of the 

 habits of Culicidae, confirming previous observations that even 

 small pools of water, especially in woods, serve as breeding places for 

 mosquitos. A. nigricans has been found in Switzerland for the first 

 time and it appears probable that it has a wide distribution. Its 

 favourite breeding places are collections of water in the trunks of 

 trees. In Sicily, the commonest Anopheline is A. claviger and a curious 

 habit of the larvae of this insect is recorded. They not only attach 

 themselves to various objects or stretch themselves at full length on 

 fallen leaves, but also arrange themselves in rows, in which position 

 they sail on the surface of the water before the wind. Although the 

 larvae of Anopheles prefer clean water, it is not uncommon to find 

 them in foul water, especially during a dry season, when they appear 

 to be able to adapt themselves to unfavourable conditions to a large
