186 ZOOLOGY. 
our species, having compared numerous specimens of both. Undoubtedly 
our species has been imported from Europe, and it would have been the 
better way, we think, to regard our. species as identical with the M. po- 
morum (Bouché) than to give it a new name 
Now this is not very consoling after having devoted nearly’ 
three pages to the reasons for the course pursued, in which pages 
every point made in the above extract is carefully met and effect- 
ually broken. It is all the less so that my reviewer has himself 
named species on very unsatisfactory grounds.* I have studied 
Mytilaspis pomicorticis for many years, and emphasized the fact 
that its eggs are never, at any stage of development, reddish-. 
brown, and that the color of the egg is a most important character 
in distinguishing the closely allied Coccide. I expressly stated - 
my belief that the European insect mentioned by Curtis, Bois- 
duval, Taschenberg and others is identical with our’ s, and showed 
that in Europe as well as in this country it had generally been 
considered as Gmelin’s conchiformis which, however, applies to 4 
similar species found on the elm in Europe, and not to the apple 
tree species under consideration. No one, until last year, even $0 
much as thought of referring our insect to Bouché’s pomorum to 
which, indeed, it cannot be referred ; and I regret that my views 
and the reasons for them are not better represented i in the above- 
quoted stricture. 
“he truth is, that if, following the highest ori we con- 
sider several very closely allied forms of Metilaspes as specifically 
distinct, the European apple tree species with white eggs, which 
is the one imported into this country, was, up to the appearance 
of my last Report, erroneously referred to conchiformis Gmélin; 
and they either have a closely allied species in Europe, with
