At the meeting of the Nonpareil Society, on September 20th, Mr. 

 Bates stated that he took twenty-four examples of Colias lujalc in a 

 lucerne field between Dagenhaui and Hornchurch, in Essex, during the 

 •second week of August. Mr. Lusby at the same time reported several 

 <7. hyale at Gravesend during August. — C. P. Pickett, 52, The 

 Havenscrofts, Columbia Eoad, Hackney Eoad, N.E. Septemher iith, 

 1900. 



Colias ediisa has been common at Oxton with the ab. helice occur- 

 ring fairly frequently, about one' in ten ; also one C. hyale, which 

 ^almost escaped notice as a poor helice. — E. F. Studd, M.A., F.E.S., 

 •Oxton, near Exeter. October 5th, 1900. 



Colias eclusa has been abundant in the neighbourhood of Braunton 

 «,nd Morthoe this summer. — C. Bartlett, 18, Henleaze Avenue, 

 Westbury-on-Trym, Bristol. October 2nd, 1900. 



I saw a specimen of Colias cdusa at Chippenham, Wiltshire, on 

 'September 24th. — Ibid. 



I captured two male Colias hyale on August 12th on the Old Fosse 

 Eoad, near Cotgrove, Notts, whilst a few days later four other examples 

 were captured in the same locality. On the same date (August 12th), 

 and in the same place, I also took 19 C. edusa, whilst a few days later 

 a friend took 53, other captures bringing the total up to 80. The 

 weather was generally sunny, with the wind westerly. — G. Henderson, 

 57, Arnold Eoad, Old Basford, Notts. October 4th, 1900. 



On August 19th last I watched with great delight two specimens 

 of Colias edusa flying about in a clover field near Painswick. I had 

 not observed this interesting species here for many years. I may add, 

 that the common Pierids are still in evidence and have been seen in our 

 •garden as late as yesterday, October 8th. — C. J. Watkins, F.E.S., 

 King's Mill House, Painswick. October 9th, 1900.

 ■during the autumn and winter months, larvse of Coleophora salinella 

 on Atriplex iwrtulacoides and Suaeda maritima ; those of Coleophora 

 tengstroemella on Chenopodium, ; of Coleophora artemisiella on Artemisia 

 maritima ; of Semasia rufillana in seed-heads of Daucus carota ; of 

 Concliylis francillonanaoxidL Argyrolepia zcphyrana in the stems of D. 

 'Carota ; in the heads of teasel, larvae of Eupoecilia roseana and Penthina 

 gentiana were abundant ; larv© of Conchylis dilucidana in the stems of 

 wild parsnip ; Gymnancycla canella on Salsola kali ; cases of Coleo- 

 phora aryentidella plentifully on seed-heads of yarrow, whilst the larvae 

 of Dichrorampha petiverana were in the roots. All these in due course
