G. B. Corbin.—Cnethocampa pityocampa and Argynnis 
Niobe.—Where is Cnethocampa pityocampa? I am led to 
make this enquiry from the fact of having been somewhat 
surprised last season at the very common occurrence of this 
species in Kent, and the silence which has prevailed this 
year with regard to its occurrence. Is the species so 
thoroughly British that no question can be raised as to its 
authenticity, or has my isolated position as a collector 
prevented me from recognising the well-known fact? Surely 
if the species was so common as represented upon fir-trees, 
they have not been exterminated in one season’s collecting, 
assiduously as that might have been carried out; or did the 
continued rains and floods of spring and early summer 
destroy the hopes of this season with this particular species ? 
Again, has Argynnis Niobe been taken this season at the 
bottom of that particular “huge rent” amongst the rushes 
in Kent, or has that also disappeared with Cnethocampa 
pityocampa? If I mistake not, it was stated in the ‘ Ento- 
mologist,’ at the time of the occurrence of Argynnis Niobe, 
that a pair were to be figured in its pages; but the non- 
appearance of these portraits seem to point to the fact that 
some doubt existed as to the thoroughly British origin of the 
specimens in question. Did such a doubt exist? To persons 
like myself, who live away from the great marts of entomolo- 
gical specimens and information, the news of a new species 
added to our native Fauna is regarded with perhaps greater 
interest than we should otherwise experience; and with 
regard to the two species, Cnethocampa pityocampa and 
Argynnis Niobe, I must say my interest and curiosity were 
awakened, but it certainly has not been satisfied; possibly, 
however, I have felt some bias from the doubts expressed 
about the thorough genuineness of all these specimens at the 
lime of their capture. I understand that Argynnis Niobe has 
unquestionably been taken in England once or twice, which 
is perhaps sufficient to establish its identity as a British 
insect ; but I had hoped that this season would have recorded 
its further occurrence in that particular locality in Kent,
