varies a good deal in the specimens, and the ground colour varies from 

 the dull yellow-red to the rich red-brown form. Pyrameis cardui occurs, 

 but rather sparingly. P. atalanta, however, is fairly common but not 

 at all variable, one specimen (September 17th, 1905) having the red 

 transverse band almost divided in two, and thus approaching ab. fracta, 

 whilst several of the others have this band divided to a less extent. 

 In size the specimens vary from 65mm. (September 16th, 1905) to 

 55mm. (September 10th, 1905). Of the Satyrids Epinephele ianira 

 and E. tithonus occur, but I have never taken either in good condition 

 here. Coenonympha pamphilus is abundant and variable. In size the 

 specimens vary from 33mm. (July 4th, 1905) to 26mm. (August 30th, 

 1906). Besides the two aberrations mentioned on page 338 of vol. 

 xvii., of the Ent. Bee., I have taken a few specimens of ab. ocellata and 

 one of ab. dbsoleta. Specimens may also be obtained with dark 

 marginal bands approaching ab. lyllus, Esp., and I have a specimen 

 with the underside of the hindwings of a dark red-brown, only varied 

 by a light curved line in the centre, thus approaching ab. unicolor. 



Butterflies in Eastern Switzerland in 1906. 



By J. N. KEYNES, M.A., D.Sc, F.E.S., and G. L. KEYNES. 



Having had several entomological seasons in the Ehone Valley and 

 the Bernese Oberland, we decided that we would, in 1906, go further 

 east. We accordingly made the Engadine our head-quarters. The 

 district is well known to entomologists, and we did not discover much 

 in the way of fresh localities ; but the information as to dates, etc., 

 given in the following extracts from our entomological diary, may be 

 of interest. 



June 2Qth. — Between Muhlehorn (on the Walen-See) and the 

 Thalalp-See. Araschnia levana was abundant and in fine condition. 

 We also took six Parnassius mnemosyne and two Brenihis thore (both $ s) 

 freshly emerged. J s of Nemeobius lucina (a finer race than that met 

 with in England) were abundant ; the $ s appeared to be over. 

 Amongst our other captures were Nisoniades tages (very large and fine), 

 Pieris napi var. 5 bryoniae (worn), and Euchloe cardamines ( ? s still in 

 good condition). 



June 21th. — Weesen Marsh. We took good series of Lycaena areas, 

 L. euphemus, and Coenonympha typhon. Even within the marsh itself, 

 however, these species w T ere extremely local, and it took some time to 

 discover the right places for them. Of the two blues L. areas was 

 much the rarer ; we did not, in either case, meet with many ? s. 

 Some of the specimens that we took of C typhon were very fine. 

 Brenihis ino was another insect common in the marsh, and Nomiades 

 semiargus was larger and finer than any we have met elsewhere. We 

 took a single specimen of Cyclopides palaemon. The heat was extreme. 



June 29th. — The Dischma-Thal, leading from Davos to the Scaletta 

 Pass. Cloudy until mid-day, then heavy rain, followed by intervals of 

 sunshine. There were never many insects flying. We took Brenthis 

 euphrosyne (small and dark) and Pararge hiera (tw r o $ s and one ? ), 

 but met with little else of interest. 



July 1st to 3rd. — Neighbourhood of Alvaneu Bad. We found 

 Alvaneu Bad a very good entomological centre, and on July 1st noticed, 

 within half-a-mile of the hotel, nearly fifty different species of butter-
