60 THE ENTOMOLOCtIST's RECORD. 



on similar slopes, receiving a similar provision of heat and cold, 

 seems to require explanation. Mr. Tutt and myself took a fair number 

 of A. jucumla near the top of the Saleve, on slopes facing the north, 

 at an altitude of about 3800ft., whereas it is generally only found at the 

 very foot of this hill, but the sunny slopes of the Vanil Noir, where I 

 took it three years ago, are at least 1200ft. higher than the Saleve. 



Lepidopterists visiting the Grand St. Bernard at the end of July, 

 or beginning of August, should take a note of the fact that Ikisydia tene- 

 braria var. honidaria Avas flying freely on the loose stones at the very 

 top of the Col Fenetre this year on July 21st, at an early morning 

 hour and in dull chilly weather. 



On August 14th, near the Chapeau, atChamonix, among a few Krebia 

 tyndartis ab. dronitift netted, I noted an aberration with four eye-spots, 

 the two lower ones being unpupilled and rather small. Since then I 

 have had the pleasure of examining a number of butterflies collected 

 by the well-known surgeon. Professor J. L. Eeverdin, of Geneva. 

 These include a very long series of E. tyndanis from different parts of 

 Switzerland and the Savoy. Among the latter are several four-spotted 

 insects and many very interesting aberrations. An examination of a 

 considerable number of these butterflies, having more eye-spots, or spots 

 more strongly marked on one side than on the other, shows that the 

 right and left sides are favoured indifferently, and, consequently, that 

 Eiihl's remarks thereupon must fall to the ground. Riihl was 

 probably insufticiently documented. Dr. Keverdin has picked up all 

 the insects he could find, and, in his drawers, I remark nearly equal 

 numbers of insects having two spots on right forewing and one on 

 left, and vice msa : one spot on one side and none on the other ; spots 

 better developed on right or left side, etc. Among the curiosities is a 

 2 ab. droninfi froiB the Flegere, with four large pupilled eye-spots on 

 each hindwing and only one tiny spot on the forewings. Another 

 from the same place has a pair of magnificent black unpupilled spots 

 on each forewing. A third, from the Gemmi, has the eye-spots in a 

 bright red band covering half the forewing. From the Flegere come 

 some beautiful three-spotted insects, ab. eaiicasira. The third spot 

 placed in the cell below that which contains the second, sometimes 

 forms a straight Ime with the two others, and sometimes is iiiuch 

 closer to the border of the Aving. From the Pierre-a-voir, Lautaret, 

 and the Flegere, come specimens of dronniK having four eye- spots to 

 every wing. In the forewings the eye-spots occupy four successive 

 cells, and, in the finest specimen, are all very large and white pupilled. 

 For this beautiful insect I was about to propose the name ab. reverdini, 

 but am informed by Mr. Tutt that it has already been named, from 

 specimens captured in the Dauphiny Alps as ab. addenda (Eut. llec., 

 viii., p. 259). There are several intermediate forms, notabl}- with 

 the third spot missing on one or both wings. Most curious of all is 

 an insect having five spots on the left forewing and three on the 

 right. The fifth is an apical spot placed near the outer margin of 

 the cell between ii,, and iiij. A second insect has this apical spot 

 on both forewings as a third spot. Evidently there is yet another 

 and richer insect than the described form to be found if properly 

 looked for. 



In several places near Geneva, in June, I have taken Coenoni/nipha 

 arcania ab. obnoleta, C. paiiij/hiliiK ab. bijnijdllata, and an ab. of ('.
