We had been attracted to this place chiefly by Mr. Wheeler's papers 

 in the Eittnmnloiiist's Rcninl, and we found he had not said a word too 

 much in its praise either entomologically or otherwise. August 15th 

 and 16th were cloudy, windy and cold, and our captures were not 

 numerous ; but during the rest of our time at Berisal tlie weather 

 left nothing to be desired. On August 17th we walked to the top of the 

 Simplon Pass, and amongst our captures were the following : — < 'idias 

 palaeno (several, quite at the top of the Pass), ( '. jildcmnunf, ( 'h)i/)i(ipliant(s 

 viri/aurcac var. zermattensiK, ( '. JiijipotJun' var. enriihia, l'oln<»iniiati(s 

 orbit ulitft, P. astrarche ab. allous, L'. rros (abundant near the fifth refuge), 

 P. eumcdon, P. donzcUi (several, but at one spot only, between the fourth 

 and fifth refuges), Ciipiilo scbms, Xoiniadcs Keuiiarpuft, Li/caena arion 

 var. (ibsciira, Kpinephele li/caon, Anp/nnix ninhf ab. crU and Cocno- 

 ni/nip/ia arcania var. danviniann (several, but on one slope only, just 

 beyond the first gallery). Fa'ebias were abundant, but, so far as our 

 captures went, limited to two or three species, ErcJyin meUunpiis, 

 K. ti/ndan(s and K. (joantc. These butterflies show a beautiful green 

 sheen when seen in the sun that renders them particularly attractive. 

 On August 19th we walked down from Berisal to the second refuge, a 

 very hot and dusty walk, but prolific in butterflies. Sati/nis /irniiidHc, 

 a very fine insect when on the wing, was abundant, especially whilst 

 we were having our lunch ; it was apparently attracted by the food 

 that we had with us. Most of the specimens that we caught were 

 rather worn ; but we got three or four good ones. Another fine insect 

 that was fairly abundant, but also rather worn, was Satt/run actaea var. 

 conlula. We also caught Aporia crataeiji (a very fresh and fine 

 specimen), Poli/oDiDiatttH cschcri (fairly abundant, but local), /'. 

 hi/las, and Spilothyrus laratcrac ; and perhaps our most attractive 

 capture on this day was a specimen of DnjciK paphia ab. ralesina, 

 which, although woi-n, was a very fine insect. On this road 

 Melitaea didi/iiia and M da nan/ i a (jalathea were very common, and 

 also some species of Surirhthas. On August 20th we walked on the 

 Bortel Alp, nearly to the glacier. It was a very tine day, but butter- 

 flies were not abundant. There were some Erebias (/','. ti/ndarns and 

 ab. cafcodromiis, K. f/oante, K. welatiipus, K. prance var. pitho), and 

 we took some tine Pieris calUdice and (at one spot only) some Cocno- 

 nipnpha arcania var, darwiniana. On August 21st we took a walk on 

 the Wasen Alp but caught nothing fresh. On August 22nd we 

 again walked to the top of the Pass and had an even more successful 

 time than on August 17th. The most prolific spot Avas on the Berisal 

 side of the Kaltwasser gallery, where we caught many species of 

 Blues, including Polijoiiniiatus pkerctes (which we had not taken before). 

 We also took three very fresh Parna-isiKx ddiuH and a particularly fine 

 Chnjsoplianm rinianrcai' var. zcniiattensis, in addition to many other 

 insects of which we already had specimens. We were rather fortunate 

 in not having passed by the /'. ildiuN as being P. apollo (which was 

 abundant, and to which we were not paying any attention). On 

 August 2 tth we left Berisal for Zermatt. On the following day we 

 walked up to the Hornli. The weather was favourable, but butterflies 

 were not abundant. We took, however, some very fresh I'ieris valli- 

 dice, Paruassiufi dditts, BrenthiH pales var. /.s/.v (which was new to us), 

 and a specimen as to which we have not yet decided whether it is 

 MeUtaea asterie, or a small 3i. aurelia. From August 2oth to August
