 Bethune-Baker both observed that on the Continent they had taken hibernated 

 specimens of the var. hutchinsoni. Dr. O. M. Eeiiter communicated a paper 

 entitled " Bryocorina nonnnlhi Aethiopica descripta " ab O. M. Reviter et B. 

 Poppius. Commander Walker, one of the Secretaries, read a paper on behalf 

 of Col. Manders, entitled, " A factor in the production of mutual resemblance 

 in allied species of butterflies : a presumed Miillerian combination of Euploeas 

 in S. India and Amauris in S Africa." The methods adopted in his experi- 

 ments, and the conclusions drawn from them by tlie author were, to some 

 extent, the svibject of criticism, both by Mr. G. A. K. Marshall and Dr. 

 Chapman. Mr. Merrifield added a few observations with regard to the com- 

 parative immunity of Pierine liutterflies from the attacks of birds. 



A vote of condolence with the family of the late Mr. J. W. Tutt was 

 moved from the Chair, all the Fellows present signifying approval by rising. —

A WEEK'S COLLECTING AT BEEISAL. 

 BY G. T. BETHUNE-BAKER, F.L.S. 



I arrived at Berisal from the Laquintlial on Monday, July 25tli ; 

 the day was cold, but at that favoured spot the sun was shining, and 

 the air very different to that I experienced over the Simplon, where it 

 was necessary to walk really quickly in order to keep warm, whilst on 

 the Kulm itself a short cold shower of sleet greeted nie. After kmch 

 I descended to the " Pont Napoleon " to explore that part of the dis- 

 trict, but beyond a few Pleheivs coridon and one or two of the commoner 

 species very little was on the wing, the day not having been warm 

 enough to induce butterflies to fly later than usual. I took, however, 

 a nice ? P. bryoiiise and Collas pliicomone. Zyyxiia traitsalpina was 

 quite fresh, the specimens being beautifully deep red in their under- 

 wings and markings, whilst an almost typical carnioliea, but with the 

 abdomen all black, accepted warmer quarters in a glass-bottomed box 

 Avithout demur ; it was, however, getting towards evening, so I returned 

 under the hospitable roof so ably and kindly conducted by Mrs. Keating, 

 and wondered what acquaintances I should make at the dinner table. 



The following day was lovely, and was spent in the well known 

 haunts of Plebehis lycidas ; on my way thither nuicli time was spent 

 in watching and taking other species. P. coridon was quite the com- 

 monest "blue" present, P. escheri came next, and of this I took a 

 good series, but females were not much " en evidence," and I only 

 obtained a single specimen ; ir.arus was almost over, tlietis also being 

 in the same condition, so that I only retained three examples. P. hylas 

 was equally scarce in that part of the valley, and I took but one,
