This very important memoir is noticed at the request of the author. 
It escaped notice in the early vols. of the Zool. Rec. (which commenced 
with the year 1864), and also in the German “ Bericht.” It would also 
appear to have escaped the notice of workers on Blattidce generally, 
for none of the new terms employed therein for generic, &c., divisions, 
are included in Scudder’s just published laborious “ Universal Index,” 
which extends down to 1879. Such, then, is the excuse for briefly 
noticing a memoir published twenty years ago, which notice must be 
limited to an enumeration of the “ new genera and species,” thus leaving 
without indication the many and important chapters on anatomy, habits, 
and classification comprised in the first 46 pp. 138 species (some new) 
are described.
