This genus comprises about thirty species, which are widely distributed ; 

 only one or two have been recorded from the tropics, but several have 

 been comparatively recently described from Southern Australia and 

 Queensland ; a rather large proportion belong to Russia, J^orthern Asia, 

 and North America ; only one species is known from South America, 

 which occurs, like so many of the more northern forms, in Chili ; there 

 are four British species ; three of these occur in haystack refuse, and 

 general vegetable rubbish, and one is found under decaying sea-weed on 

 the shore ; they are very rapid in their movements.
