t In the table the records of Hydrobius fuscipcs and picicrus, of Anacsna limbata and 
bipustulala, and ot Octhebius bicolon and aer&tus are mixed. Also probably some of the records 
of Hydnena testacea should be referred to H. palustris. 
1 This species cannot he considered of any importance in the table because it is much more 
commonly found out of water than in it. Several other species, such as those of the genus 
Limnebius, and also Cyclonotum orbiculare, are also found in damp moss and such situations, so 
that their occurrences in water are not a sound criterion of their abundance.
