38 THE ENTOMOLOGIST. 
Mr. Mosley quite sure that his insect is the true C. Scrophu- 
lariz, which closely resembles C. Lychnitis, but is very 
different from C. Verbasci:—Henry Doubleday; Epping, 
January 14, 1875. 
Arctia Isabellan—An American friend sent me a lot of 
Arctia Isabella larve over from Illinois. They seem to have 
borne their journey remarkably well, for they were alive and 
in pretty good health on arrival, after a journey of about a 
fortnight through the post.—J. C. Wassermann. 
Note on Eupithecia Knautiata, mihi.— 
“T understand thy kisses, and thou mine; and that’s a feeling dis- 
putation.”—SHAKESPEARE. 
At page 290, vol. vil., of the ‘Entomologist,’ Mr. Crewe 
says he has read with “considerable astonishment” my note 
on an Eupithecia I have called Knautiata, and is wholly at a 
loss to know by what process of reasoning I have arrived at 
my conclusions; and that he has had the Bolton insect from 
the egg up to the moth, and, after careful consideration, he 
is convinced that it is nothing but E. minutata. 
In reply to all this, first, 1 ask him to re-read my note 
without any “considerable astonishment,” and then compare 
my description of its larva with his own description of the 
larva of E. minutata, as copied into Newman’s beautiful 
‘British Moths,’ p. 1387, by his permission, and if he is not 
considerably astonished at the great difference in the 
descriptions, and if he can then make them identical, I shall 
read his report with considerable surprise ; secondly, I arrived 
at my conclusions, as I usually do in natural history, from 
facts, not seasonings. Iam nota speculative naturalist, and 
in this case I personally ascertained that this larva fed on 
Knautia arvensis alone, at Bolton, and of course knew, as 
well as Mr. Crewe, that E. minutata fed on heath. I then 
went ninety miles (to North Lancashire), where I knew 
Knautia arvensis grew on a fell amongst heather, failing .to 
find a pug larva on the Knautia, where plenty of Minntata 
were feeding on the ling. I went pike fishing, on Easthwaite 
Lake, next day; I walked some twenty-five miles over the 
fells to Moss End, Witherslack, where I knew plenty of 
Knautia grew on the moss amongst fine heather ;—no results. 
Proceeding to Grange-in-Cartmel I got the last train for the 
South, and got home after midnight. Not satisfied, I went to
