them members of the genus Culex. The one point 

 of similarity between the whole lot lies in the fact 

 that they all suck blood ; whenever a blood-sucking 

 culex is lighted upon in England it i> called a 

 gnat ; while whenever one is found in any other 

 part of Europe, Asia, Africa, or America, we say

 they come out in swarms during the short summer ; 

 and wherever ponds or stagnant waters abound in 

 Finland or Alaska, they bite quite as successfully 

 and industriously while they last as in Ceylon or 

 Jamaica. At least a hundred and fifty kinds are 

 " known to science," and of these, no fewer than 

 thirty-five occur in Europe. There are nine in 

 Britain. Most of the European species bite quite 

 hard enough to be popularly ranked as mnsquit<
