156 THE ENTOMOLOGIST. 



On July 29th I cycled to Talylyn (ten miles), left my machine 

 at a farm house and started to climb Cader Idris (2920 feet). 

 There was a cloud over the peak, but in my inexperience I 

 disregarded it, to my cost. The path leading from the road 

 through a belt of scrub oak was covered with loose pieces of 

 slate, rather trying to one's boots, and beating the oaks only 

 produced Eucosma arcuella and Gracilaria alchimiella (sivederella) . 

 On emerging from the tree belt I netted a dipteron, which has 

 been kindly identified by Mr. Claude Morley, F.E.S., as 

 Therioplectes distingue ndus,, Verr., and then went through a farm- 

 yard, where the farmer's wife obligingly directed me to the best 

 way up the mountain. On the way up I netted two specimens 

 of Coenonympha pamphilus in the hope that they were C. tiphon. 

 The west wind from the sea made a net practically useless had 

 there been anything to catch, but only a larva of Eriogaster rubi 

 was observed sunning itself on a stone amongst whortleberry. 

 When 2000 feet up I had a glorious view of Snowdonia. A 

 little further on I was swallowed up in the mist but nevertheless 

 proceeded to the summit, where I was just able to look down the 

 precipice into the tarn called Llyn Cau. On the return journey 

 on the roadside at the foot of the mountain I noticed a nest of 

 Vanessa io larvae about three-quarter grown feeding on the 

 nettles. August 2nd being fine we walked to the Bird Bock, 

 a mountain rising 1000 feet sheer out of the valley, the home of 

 the cormorant and other sea birds, but the only species noted 

 worth mentioning was Endotricha flammealis. To visit Mr. D. A. 

 Jones, M.Sc, of Harlech, twenty-three miles away, I cycled 

 through Barmouth on the 5th. Just before I came in sight 

 of the picturesque ruins of Harlech Castle a freshly emerged 

 $ Gonodontis elinguaria was boxed from a telegraph post. 

 Tephroclystis subfulvata and T. nanata were boxed from a fence 

 near Barmouth. Next day on the way to Owen Glendower's 

 Cave at Tonfanan a burying beetle, Necrophorus rustator, was 

 noticed at work on a dead Meadow Pipit. A solitary Polyom- 

 matus icarus was seen on the sandhills of Aberdovery on the 7th, 

 and a green bottle fly was found impaled on a spike of marram 

 grass. On the railway bank adjoining the sands of Towyn, where 

 the seaside Everlasting Pea (Lathyrus maritimus) was growing, 

 Hipparchia semele, Chrysophanus phlaeas, Plemyria galiata, 

 Zygaena filipendulae, Eucosma cespitana, Tortrix conspersana 

 and Anacampsis taeniolella were taken. Other captures included 

 Opostega salaciella (on some iron railings near the shore on the 

 13th) Lithocolletis alnifoliella and Ochsenheimeria birdella. My 

 wife found a larva of Notodonta ziczac on poplar on the 9th. On 

 the 11th I cycled to Dolgelly. My only capture there was 

 Scoparia ambigualis. On the 15th O. birdella $ was observed at 

 rest on a gate-post on the local marshes where Juncus acutus 

 was growing, and also a worn pair of Zygsenas in cop. on flowers
