8 THE EKTOMOLOGIST. 



the original specimens or parents have come over to this country 

 from Hehgoland, either by their own unaided flight, or else as 

 stowaways on board ship. The chances of their distribution 

 inland would be materially increased by means of the railway. 

 I have frequently known southern insects to be found in waggons 

 arriving in York from the south.

ON ZYGjENA EXULANS and Vak. SUBOCHKACEA, White. 

 By W. H. Tugwell. 



In the ' Entomologist's Kecord ' for November, 1894, is a long 

 and interesting article by Mr. Tutt on Zygcena cxulans, and 

 certain very beautiful forms of this species that Dr. Chapman 

 and himself had met with when on a tour over that entomological 

 "El Dorado," the French, Swiss, and Italian Alps, during the 

 last week of July and part of August. Mr. Tutt exhibited some 

 of these very line forms, and read notes on them, at the Entomo- 

 logical Society, and also at the South London Entomological and 

 Natural History Society. One of the objects of the exhibition 

 and remarks thereon appeared to be the upsetting of var. suh- 

 ochracea, Mr. Tutt considering that the " Braemar form, which 

 Dr. White named var. subochracea (on his first discovering the 

 insect in July, 1871, and cited in Entom. vi. 22), was only so 

 named in consequence of their worn condition," and stated that 

 the few specimens I had given him in 1886 " corresponded excel- 

 lently with Dr. White's definition of what a Scotch Z. exidans 

 (a somewhat diaphanous form) should be. They evidently 

 belonged to the variety which Dr. White created specially for 

 these rather rubbed specimens." But surely Mr. Tutt knows well 

 enough that out of the long series Mr. L. Gibb and myself 

 secured on our trip in 1886 many of them (50 per cent.) were 

 in the finest order. That Mr. Tutt only had but moderately 

 good ones was due doubtless to the fact that he never gave me a 

 specimen of any kind, and we are naturally inclined to help those 

 best who assist us. Still, one thing is evident : poor as they 

 were, it has taken him six years to improve on them. But for 

 Mr. Tutt to remark that it is only this year that we have learned 

 how "really fine Scotch exidans ought to look," is simply 

 ridiculous, as from 1886 to present time I have distributed to 

 my friends over 1000 specimens, a large percentage being in the 

 finest condition, and fully equal to any seen this year. 



The curious part of Mr. Tutt's exhibit was that prior to 

 showing them he had taken the extraordinary course of repinning 

 and resetting some of his Scotch specimens, and then mixing
