66 Pipunculidae. 



The species of Verrallia are found in the same piaces as the 

 species of Pipunculus, and they behave in the same way. 



The genus is a small one, containing, I think, in all only seven 

 species from Europe, North America and China; of the three palæ- 

 arctic species two have been found in Denmark.
