After examining the ample material quoted above, I feel 
convinced that F. aceris and F. beelzebub are one species: t 
colour ranges from a bright blackish red to deep black; the 
armature of the dilated portion of the forceps varies, as 
the sculpture, with the size and development of the individuals. 
t is possible to arrange a long series, the extremes of which 
are totally different, but it is impossible to say where F. aceris 
ends and F’. beelzebub begins. _
