identical with most of the unspotted males, only Hiibner, strangely 

 enough, whilst showing the colour dimorphism that exists between 

 the sexes, has transposed the bodies, so that figs. 491-492 have ? 

 coloration and ^ body, whilst tigs. 498-494 have S' coloration and 

 $ body." Berce (p. 188) makes the following suggestive observation 

 about M. pliarte : "A little larger than indampm, from which it differs 

 in that the ferruginous blotches are altogether devoid of black points, 

 those of the superior wings more rectangular, those of the inferior 

 wings a little oval. It has the same habits as melampun, and is found 

 at the same time, and in the same localities. ' Mdainpias cctn. — 

 Two specimens only were captured, both worn, so that the species 

 was probably going over. These were both captured close by the 

 Hospice. Kane gives Lautaret as a locality for this species. Krchia 

 mnestra. — A single female specimen of a species of Erebia, which I 

 think must be referable to this species, was captured. It is of a dark 

 fuscous brown colour, with an ill-defined unspotted tawny band 

 running parallel to the hind margin of the fore-wings, and continued 

 faintly on the upper half of the hind-wings. The underside of the 

 fore-wing is bright tawny, except for a grey-brown outer margin and 

 a narrow grey-brown costal margin. The hind-wings grey-brown at the 

 base, extending rather more than half way over the wing, followed by 

 a pale grey band, and with the outer margin of the same colour as the 

 basal area. Those who know the ordinary form of K\ imu'stra, 

 especially the male, will recognise that this is very different on the 

 underside, and its banded character gives us (if I am right in my 

 determination) a species in which the male belongs to the " Epiphron- 

 vu'laiiijms group," whilst the female approaches the " ti/ndai-iis group," 

 I see that there is a female specimen with a trace of the band on the 

 underside of the hind-wings in the British Museum collection, but this 

 specimen possesses also ocellated spots towards the apex of the 

 upperside of the fore-wings, which the Lautaret specimen lacks. Erclna 

 tj/ndaius. — The specimens of this species are remarkably well 

 marked, they are also of very fair size. The males have the fulvous 

 patch variable in size (in some it is almost absent) ; in the females 

 it is much larger, in one, occupying all the central area of the wing, 

 almost to base. In another female it is of an orange tint. 1 here 

 are usually two well-developed ocellated spots on the fore-wings, and 

 three or four on the hind-wings. In one J" and one ? the ocellated 

 spots on the fore-wings are much reduced, but none have them quite 

 absent, nor without white centres. I saw nothing resembling the ab. 

 coecodromm from Mont de la Saxe, the Penegal, and Oberalp. One 

 female has four large well-ocellated spots on fore-wings, another with 

 two large ocellated spots and two blind smaller ones beneath. The 

 form with extra ocellated spots on fore-wings I would call ab. addenda. 

 One $ and one ^ are pallid, the pigment largely failing. Two forms 

 of the underside of the hind-wings occur : — (1) Dark grey with darker 

 central band. The females of this form have the ground colour paler 

 grey, with darker central band. (2) Dark grey, unicolorous, with only 

 the faintest trace of transverse lines. The ? s belonging to this form 

 have the underside of hind-wings unicolorous, greyish or silvery- 

 white. There is a faint tint of ochreous in the undersides of a few of 

 the specimens. Erebia (/on/e. - Only two specimens captured, owing to 

 the clouds that persisted about the highest peaks, Probably the
