sleeping, but so Uglitly that your step disturbed it at once, and it wat| 

 off over tbe heather, far away, yet the grey boulder gave it fai' 

 greater protection than the yellow populata could ever have. Here 

 then, was a day of brilliant sunshine spent amongst the mountains 

 and though diligent search was made, the only Lepidoptera seen werf 

 six butterflies : Lyccena Icarus, one ; Vanessa urticce, one ; Chionoiai\ 

 Jufta, one ; Erehia Blandina, two ; Pararge Siera, one. Geometrce. 

 four species : Larentia didymata, ccesiata, Cidaria populata, Ortlwlitlin 

 limitata; Mimoeseoptilus fuscodactylus ; SimdetJiis Falriciana ; Ahlahia 

 pratana. If results be measured by specimens, a very poor result of 

 a long day's walk and work.

P.S. — To-day and yesterday, September 6th and 7th, I took six 



specimens of Flatyptilus gonodactylus amongst colt's-foot. This 



insect is well-known to be double-brooded, and that this is a second 



brood seems proved by my having in a former year taken the same 



plume at Christiania in June. The autumn specimens, as in England, 



are rather more dusky than those caught in summer.

Parnassiiis Delius, Esp., captured in North Wales. — A specimen of Parnassius 

 Dellus was taken this summer near Bangor by Mr. E. W. S. Schwabe, a youthful 

 pupil of this College, and was lately submitted to me for identification. It is the 

 ordinary alpine form of this species, which is stated to be more restricted in range, 

 and more exclusively alpine, than the commoner P. Apollo. Mr. Schwabe informs 

 me that he took the specimen on September 1st in the mountains above the Penrhyn 

 slate quarries, about seven miles from Bangor, near three small lakes ; the sun was 

 shining, but there had been rain earlier, and the insect was in a semi-torpid condition, 

 and easily captured ; it is rather worn. Thex-e can be no question of the authenticity 

 of the capture ; yet I think it must be regarded as highly improbable that the species 

 is a native of these shores, or even an occasional immigrant. The most reasonable 

 explanation seems to me to be that some admirer of the insect has imported pup», 

 bred the butterflies, and turned them out in the Welsh mountains as the most 

 suitable situation, in the hope that the species might establish itself. Perhaps some 

 information may now be forthcoming. — E. Meyrick, The College, Marlborough ;

[We fear it is useless to attempt to naturalize Parnassius here unless the 

 Butterflies be " preserved " by Act of Parliament with the direst penalties for 

 infringement. They are probably the easiest to capture of all Butterflies. — Eds.] 



White Butferjiies. — I can testify to the abundance of White Butterflies at 

 Inverness dui-ing the last four or five days of August, and the first fortnight of 

 September in the present year, especially as compared with the same period last 

 year, when the weather was much finer. They were mostly P. rapce. I take this
