Colias Edusa in Orkney.— My neighbour, Mr. Stuart M. Burnett, saw a 

 specimen of Colias Edusa in Harray, Orkney, on the 19th of last month 

 (June), and chased it for some time — unsuccessfully however. He was 

 quite close to it and distinctly recognised the species, having taken it in 

 England. — W. Tait, Broomend, Inverurie, Aberdeenshire, July, 9 1877. 



Colias Edusa in South West of Scotland.— For the last ten days or so 

 I have begun to see the second brood of Edilsa, of which the first brood was 

 not uncommon in June. — W. D. Robinson-Douglas, Orchardton, Castle 

 Douglas, September 3, 1877. 



Mustela erminea.— When on a visit to a friend in Newton- Stewart lately 

 he showed me a stuffed Ermine, which had been caught in the Wood of 

 Cree, near Newton- Stewart, in the gamekeeper's trap. He told me that 

 several more had been caught in the same way, and that the gamekeepers 

 called them *' white weasels." — James M'andrew, New Galloway. 



NOTE ON THE ZOOLOaY AND BOTANY OF QLEN TILT. 

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



IT was my intention to have given the readers of the Scottish 

 Naturalist some account of the natural history of Glen Tilt, but 

 this must be relinquished till a future occasion. In the meantime, 

 there are a few species that I wish to take an opportunity of 

 noticing. 



During a visit to Glen Tilt last July, I was especially struck with 

 the wide range, and abundant occurrence, of a species of Orthezia, 

 an insect belonging to the Cochineal family (or Coccina) of the 

 Hemiptera. 



Without close examination this insect would very likely be 

 passed over as the common O. iirtica; L., and it is only by 

 a careful study of the admirable descriptions and figures given by 

 M. Signoret, in his essay on this family, in the " Annales de la 

 Soci(5t(? Entomologique de France," and by comparison with 

 specimens of what I take to be the true U7'tica\ that I have come to
