striolatum came out on October 5th ; this, however, may have been 

 a case of prematurity rather tlian delay. The nymph was one of a 

 number I had just got from Angarrack marshes in Cornwall, and 

 the general excitement of the violent disturbance may have brought 

 about emergence. At any rate, I have noticed that very often when 

 nymphs have just been caught and removed to new quarters, one or 

 more of them emerge at once, no others coming out until after a 

 considerable interval of time. I think the general lateness this year 

 was largely due to the coolness of the summer, A hot spell usually 

 brings out many dragonflies ; while nymphs apparently fully mature 

 and showing the usual signs of contemplated emergence will not 

 come out on a cold day ; protracted coolness causing some of them 

 to give up the attempt for the whole season, sometimes apparently 

 with fatal results. — Harold Hodge ; October 1st, 1915. 



Zyg^na filipendul^ and Macrothylacia rubi on the Hayle 

 Estuary. — There is an entomological phenomenon about the Hayle 

 Estuary, in Cornwall, which seems worth recording. At low tide 

 the estuary is certainly not more than three hundred yards wide in 

 parts, and divides an absolutely homogeneous terrain. Yet on one, 

 the Lelant, side the cocoons of Zygana filipendulce are to be found 

 in thousands ; on the other, the Hayle, side hardly one is to be seen. 

 I have visited this part in the autumn, staying some four or five weeks, 

 for now many years following, and I have not found more than three 

 Z. filipenclulcz cocoons on the Hayle side. In exactly the same case 

 are the larvae of M. ruhi, swarming on the Lelant side, not seen 

 on the Hayle towans on the other side. The phenomenon is constant 

 year after year. — Harold Hodge ; 9, Highbury Place, London, N. 



Thecla ^sculi in the South op France : Errata. — Page 240, 

 for "^" read "to." Page 241, line 2 from top, there should be a 

 comma after lighter ; line 5 from top, after "lighter " insert " than " ; 

 and line 6 from top, after "diminishing" insert "much"; line 18 

 from top, for "dark" read "light brown." I much regret these 

 errors, probably due to my inaccurate transcription of the MS. notes 

 so kindly placed with me by Dr. Eosa. — H. E.-B.

The South London Entomological and Natural History 

 Society.— ^w^t^si 26^/i. — Mr. A. E. Tonge, F.E.S., Vice-President, 

 in the chair. — Mr. Main exhibited leaves of the sycamore in which 

 were the larvas of the Sawfly Phyllotoma aceris, and leaves of alder 

 in which another species of Phyllotoma fed in a somewhat similar 

 manner. Mr. Edwards, butterflies from S. America of the genera 

 Gybdelis, Cyclogramma, Cotenephile, and Myscelia, showing marked 

 seasonal dimorphism. — Mr. Newman, a " blue " captured in Kent in 

 July, which, from its colour and markings, he considered a hybrid 

 between Agriades coridon and A. adonis. — Mr. Bunnett, bunches of
