fasctaiiiwwAl'. sKhmiiiidln, wiiioli I have dcscrihcd as n Mucaria {Semiothisa) , 

 is an artificial one. I believe that Semiotliisa and P/iadane originated from 

 llie same stock, since tlie generic (diaracters of these species agree remarU- 

 ;d)lv. Tiiis converging of generic characters of the lower species of allied 

 genera is seen tiiroughout the family, and probably indeed in almost every 

 familv and group of the animal kingdom. In like manner, the distinctions 

 l)et\veen tlie two aljove-mentioncd genera and Euholia and Diastictis are 

 highly artificial, and I adopt them as genera simply for convenience. It is 

 putting nature in a straight-jacket for a temporary purpose.
