chalk hills near Eeigate, September 4th, 1900.— E. M. Pridbaux, 

 Eeigate Hill, September 1th, 1900. 



I saw two male Colias edusa on September 6th, near EasingAvold, 

 about twelve miles north of York. — S. Walkee, Eddercliffe, Queen 

 Anne's Eoad, York. September 9th, 1900. 



On August 19th, I went to Heme Bay with a friend, where we 

 captured ten specimens of Colias hyale (both sexes), but only saw two 

 C. edusa. On September 8th I went to Boxmoor, in Herts, with my 

 uncle, Mr. A. Cottam, but the sun, although shining hotly before we got 

 to the field, suddenly clouded over, and we only saAV two C. hyale, both 

 of which we took. I may add that when my uncle was at Bridgwater 

 he captured several C. edusa, and in one clover field on one morning, 

 he took thirty, including ten females, of which three were ab. helice. — 

 T. M. Cottam, Threadneedle Street, E.G. September 10th, 1900. 



Colias edusa has been moderately common in this neighbourhood 

 during the autumn. — N. M. Eichakdson, Monte Video, near Wey- 

 mouth. September lltJi, 1900. 



During August I have been travelling in the southern part 

 of the dept. of Finisterre ; the weather was rarely very fine, 

 although in Cancale just previously it had been superb. I am 

 particularly interested in Colias edusa and C. hyale. Both species are 

 this year very rare in Brittany. In Finisterre I have seen very few 

 C. edusa and no C. hyale. At Cancale I was out every day, and here, 

 neither species was at all abundant, C. hyale even rarer than C. edusa. 

 I saw perhaps, on an average, from six to eight C. edusa and two to 

 four C. hyale each day. The former is extremely common some years, 

 but this year, as I have said, C. edusa is rare. In my garden Argynnis 

 lathonia, Pyrameis cardui, P. atalanta, Polygonia c-album,, Colias edusa, 

 C. hyale, Lampides boetica, Polyommatus icarus, P. astrarche, Chryso- 

 phanus phlaras, Gonepteryx rhamni, Pararye egeria, P. meyaera, 

 Coenonympha pamphilus, Hipparchia semele, Pieris rapae, P. napi, and 

 Syrichthus malvae have been flying. I do not remember having seen 

 any other Diurni, between September 2nd and 14th. The best Noctuid 

 that I have taken was Heliophobus hispida, and I have seen Eubolia 

 peribolata. — C. Oberthue, F.E.S., Eennes. September 15th, 1900. 



During a visit to Burgess Hill, in Sussex, extending from July 17th 

 to September 10th, I saw a fair number of Colias edusa and C. hyale. 

 The species were always seen together, either on clover in the weald 

 or on the downs. The dates on which C. hyale were taken are as 

 follows : — August 10th, two ; August 11th, two ; August 13th, one ; 

 August 14th, one; August 15th, two; August 16th, three; August 17th, 

 three; August 18th, one; August 24th, one; August 25th, three; 

 September 3rd, three (including one white specimen) ; September 4th, 

 one; September 6th, one. C. edusa was seen in fairly h.vge numbers 

 on all these dates. On September 17th, two examples of C. edusa were 

 seen in Belmont Eoad, Tottenham. — J. C. Dollman, Bedford Park, 

 W. September 11th, 1900. 



I observed Colias edusa and C. hyale first on Saturday, August 

 18th, when Mr. Mera came to see me, and captured fourteen C. hyale 

 and two G. edusa. I had seen none earlier, and from the fine condition 

 of the C. hyale I should suppose they had just appeared. I went out 

 myself on August 21st, and took sixteen C. hyale with one C. edusa. 

 On August 29th I took thirteen C. hyale and five C. edusa, on the
