298 THE ENTOMOLOGIST. 



one specimen drying its wings on a grass stem ; Phytometra 

 viridaria (anca) ; Larentia olivata, a very common insect, and 

 obtained by beating ; B. repandata, and the lovely black-and- 

 white Enny cilia octomacidata. I was puzzled here, at first, with 

 the local form of B. repandata. I had just seen the darker, 

 well-marked Delamere form, and the still darker indistinct species 

 of Westmoreland and North Lancashire ; but this approached 

 more in appearance the light markings of the Buckinghamshire 

 Tephrosia crepuscularia. 



The following day was as fine and sunny as could be desired. 

 Mr. Kerr and I set off, after breakfast, for a tramp through the 

 mountains in the direction of Harlech, on the coast. On the 

 hills in August is not the best time for Lepidoptera ; but we 

 came across an occasional Lycana icarus, and the irrepressible 

 P. gamma, whose pretentious flight made us wish the pursuit it 

 beguiled us into — in the hot sun — had been directed in a better 

 cause. Aphomia sociella, Cramhus tristellns, C. margaritellus in 

 ivory and gold, and C. inquinatellus, we were able to add to our 

 list of Micros. Two mountain lakes — Upper and Lower Tecwyn 

 — we now passed. The waters of both were as clear as crystal, 

 delicious and refreshing. On the banks of the Upper Lake — 

 that nearest the sea — we halted a few minutes to look at the 

 interesting scene. Around us the auriferous rocks had been dis- 

 turbed in various places in the late " discoveries " of gold. Many 

 of the stones lying about — in fact, most of them — showed traces 

 of the precious metal, but only as if a brush had lightly touched 

 them with the thinnest possible solution. The workings were 

 therefore deserted. This lake lay in a mountain gorge, at the 

 end of which, through a V-shaped opening just above the lake, 

 we could see, in the clear perspective, the blue waters of Cardigan 

 Bay. Around us rose cliffs to a dizzy height, and, against one 

 of these, sailed a solitary cormorant — the only exception in this 

 picture of still life. Shortly after we were once more in the low- 

 lands, and following the well-shaded line of a clear trout-stream, 

 by which we lunched, in the direction of Harlech Castle. All 

 along we met with A. adippe, A. papliia, Hesperia sylvanus, and, 

 in addition, a few very worn specimens of A. aglaia. T. quercus 

 was again in plenty, high up around the oaks, whilst Pararge 

 megcera and Satyrus semele winged their way over humbler haunts 

 nearer ground. And so, through " these delightful pleasant 

 groves," we arrived, after some fifteen miles of tough tramp, at 

 the estuary of the unpronounceable river which flows into the 

 head of Cardigan Bay. This estuary is guarded by an embank- 

 ment which is a well-known haunt of Colias edusa and C. hyale, 

 but it was now too late in the day, and we saw none. We 

 therefore crossed by the railway-bridge to the hotel at Mynfford 

 Junction. Here, according to arrangement, we were met by a 

 groom, and we were soon trotting back, in time for dinner, along
