38 THE ENTOMOLOGIST. 



Mr. Mosley quite sure that his insect is the true C. Scrophu- 

 larige, which closely resembles C. Lychnitis, but is very 

 different from C. Verbasci ?— //<?«r^ Douhleday ; Eppitig^

Arctia Isabella. — An American friend sent me a lot of 

 Arctia Isabella larvae 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. — 



"I understand thy kisses, and thou mine; and that's a feeling dis- 

 putation." — Shake speare . 



At page 290, vol. vii., 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 

 ray 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, I 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. 137, 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 surjorise ; secondly, I arrived 

 at my conclusions, as I usually do in natural history, from 

 facts, not reasonings. I am not a 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 Minutata 

 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
