Rhynchophorous Coleoptera of Japan. 73 
Very similar to P. perlatus, Chap., from which it may 
be distinguished by its smaller size, the absence of a 
carina on the epistoma, the frontal median elevation not 
reaching to the mouth, by the absence of a longitudinal 
elevation from base to apex of the thorax, by the 
shallower and evidently punctured elytral striz and the 
distinct rows of bristles on the interstices, which are 
alternate towards the apex; a similar row of scale-hke 
bristles occurring in P. perlatus cannot be distin- 
guished from the general covering with a lens. ‘The 
alternation of these bristles will also differentiate it 
from P,. lewist.
