GLEN TILT: ITS PAUNA AND PLORA. 



By F. BUCHANAN WHITE, M.D., F.L.S. 

 ( Contimied from page 1 90. ) 



C^ LEN TILT is as rich in the smaller moths as it is in the 

 JT larger and more generally collected species. Amongst 

 those more worthy of a special notice are Scopida uliginosalis 

 (the alpinnlis of British lists), which occurs in grassy places on 

 the hills. Much rarer is S. decrepitalis, of which I have only 

 seen a single specimen on the grassy banks of a burn, at about 

 600 feet altitude. It is possible that we have always been too 

 late in the season for this species, or else do not know how to 

 look for it. Of the genus Scopai'ia several species are common : 

 amongst others, the one known as atomalis, but which I strongly 

 suspect is only a form of the common ambigualis^ which I do not 

 remember seeing in the glen. S. iniira?ia is also common enough; 

 but alpina^ which ought to occur, and probably does, we have 

 not yet found. 



Several species of Crambus have been noticed : amongst others, 

 the rare uiyelliis is said to have been taken in the glen, but we 

 have not met with it. C. fiwcatelliis occurs on Ben-a-Ghlo, and 

 C. ericelliis in shingly places near Forest Lodge. In this locality 

 ericelltis\\2i% the annoying habit of diving into the crannies amongst 

 the loose stones, where it is impossible to get at it. Further up 

 the glen, a form much smaller than the usual one of this moth 

 occurs. This I was in hopes would prove to be another species ; 

 but I cannot see any points of distinction except in the smaller 

 size. Lower down the glen, the rather local C. dwnetelhis is not 

 uncommon. 



Of the Tortf'icifia a good many species occur. Tortrix ictera?ia, 

 which is not a common Perthshire species, seems not very rare 

 in one spot in tlie woods. Amphysa gerniiigana is found on 

 heathery banks ; and a few specimens of Pejit/iina inargitiana 

 have been taken. At an altitude of 2300 feet and upwards, P.
