and entirely black as far as the last joint, which is brown. 

 The abdomen somewhat thicker, the valves of the saw black 

 and hairy, the anal processes projecting considerably. From 

 half-way the femora the legs are entirely red-brown and 

 shining, with the exception of a longitudinal black line on 

 the under side of the femora. The wings have the stigma 

 white at the base. 



NOTES ON COLLECTING IN GLEN TILT. 

 By F. Buchanan White, M.D., F.L.S. 



It is a very long time since Mr. Douglas, climbing up Ben 

 Ghlo, found the first British specimen of Pachnohia alpina 

 sitting on a rock, and contemplating (let us suppose) the 

 beauties of Glen Tilt. After having yielded Pachnobia, no 

 more is heard, entoraologically, of Glen Tilt for many years, 

 when the announcement is made that Crambus myellus has 

 been captured there. Again the glen rested for a few years 

 till a favoured few had opportunities of exploring its inmost 

 recesses, and bringing to light its hidden treasures. 



Those collectors who have been " privileged " to visit the 

 happy hunting-grounds of Rannoch must not think that 

 Glen Tilt is at all similar in its physical features. In the 

 one case you have a large lake surrounded by extensive 

 woods of birch or fir, giving way in many directions to 

 natural meadows or heather-clad moors, and backed by moun- 

 tains of various altitudes and at various distances. In the 

 other, at least in so far as the part of it 1 am about to 

 describe is concerned, you have a long and very narrow 

 valley, through which darts a rapid mountain stream, 

 from whose banks the hills rise, almost directly, in steep 

 green slopes, topped here and there by rugged rocks or banks 

 of loose stones. Trees there are almost none, except a few 

 alders and birches beside the river, or in some of the almost 

 inaccessible ravines, down which the tributary streams pour 

 their waters into the Tilt. Lower down the glen trees become 

 more numerous, and at Blairathole form large and varied 

 woods, but in the part of the glen where most of our collect- 

 ing has been done trees are few and far between. Through 

 the glen goes a rough road, connecting Blairathole and 

 Braemar, and which is only a bridle-path for many miles. (I 

 ought to mention that though this road can be used by the 

 public, there is no liberty to go off it, and that all the 

 district is strictly "preserved" and well guarded).
