ZYG^NA EXULANS VAR. SUBOCHRACEA. 9 



them up with his continental examples in such a manner that 

 no one but himself could have the remotest chance of using his 

 own judgment as to their approaching each other, as Mr. Tutt 

 simply refused to say which were continental and which were 

 Scotch. He merely stated that "they were alike." Now one 

 thing is self-evident : they either do or do not overlap each 

 other in form. And may I be allowed to suggest to Mr. Tutt that 

 it would have been much more satisfactory and conclusive if he 

 had permitted others than himself to have seen the continental 

 specimens arranged side by side with the Scotch ; and then, as 

 may be quite possible, others could have been convinced of the 

 fact, and have seen for themselves that Dr. White's varietal 

 name was superfluous. As it stands, no one can gainsay Mr. 

 Tutt's statement, as they have no possible means of judging for 

 themselves. Mr. Tutt very kindly brought his specimens to me, 

 but, as he still followed the lines of his previous exhibit in 

 London, I could only admire some of the most striking varieties. 

 It was abundantly clear that many of them were so different 

 that they looked as if they might belong to another species. 

 Some of the specimens may have approached each other very 

 closely, but his curious mystery of mixing and blankly refusing 

 to point out the Scotch and continental individuals made it im- 

 possible for me to follow his statement. This may he " science," 

 but evidently I have not been educated up to this manner of it. 



The box of specimens Mr. Tutt showed me contained possibly 

 some forty or fifty specimens, and, referring to one row of a 

 grand form, totally unlike any Scotch I had ever seen, I ventured 

 to say that not one in that row was Scotch. Mr. Tutt said, 

 " Yes, there is." " Which one?" I asked. He would not say. I 

 then remarked that I knew every one that had ever been on the 

 ground since 1872, and I should be glad if he would say who had 

 parted with such a grand variety. Mr. Tutt warmly refused to 

 say; and so the statement stands. As I could not get any very 

 definite information from Mr. Tutt, I wrote to Dr. Chapman, 

 telling him I was much interested in the Zyga3nid8e, and that 

 Mr. Tutt had shown me some of their joint captures, but that 

 he absolutely refused to indicate which were the continental 

 specimens he stated to be like the Scotch. I asked Dr. Chapman 

 to kindly judge, if 1 forwarded him a box of Braemar insects, if 

 they were like some of his continental specimens, and telling 

 him of the different views Tutt and I held ; or would he kindly 

 loan his continental forms to me ? To this Dr. Chapman most 

 kindly replied that he was " sorry to be unable to help me in 

 exulans, as, although he had taken most of the specimens, he had 



passed them all over to Mr. Tutt We met with exulans in 



several places ; but in two excursions, when not accompanied by 

 Mr. Tutt, 1 met with it abundantly at Lauteret, where it was 

 magnificent, in size, colouring, and density of scaling, so that I
