130 Mr. Malcolm Burr’s Preliminary Revision of the 
I have erected this new genus, of which P. simulans, 
Stil, may be regarded as the type, for those somewhat 
smaller species, generally brown or reddish in colour, 
though sometimes black and variegated, which are closely 
allied structurally to Ch. morio, and long regarded as 
congeneric with that species; they have, however, a 
different appearance, but I was long unable to find a 
satisfactory character common to all the species; in P. 
simulans, the antenne are noticeably thin and slender, but 
P. ritseme approaches nearer to Ch. morio. The shape of 
the pronotum is that of typical Chelisoches, as also that of 
the feet. 
The type is Forficula simulans, Stil, Eug. Resa. Ins., 
p. 302. (1858.)
