Peters] 
Note.— Whereas we have not examined the female type specimen of /. margaritiferus, and 
the male specimens described by Karsch (1881) and Attems (1899), we feel that species attribution 
is unproblematic. We have examined P. philippinorum and P. mey^enii male types, considered jun¬ 
ior synonyms of /. margaritiferus by Attems (1938) and Peters (1864), respectively, so we are con¬ 
fident that we understand their concept of /. margaritiferus Gervais, 1836.
