224 THE entomologist's record. 



or preparing to take shelter. This was particularly the case with the 

 sheep's bit Scabious {Jasionc moutana) every head of which had 

 hanging to its underside one or more Lyctenids. I'nlj^niiniiatiis icarns, 

 A,ricia medon var. alpina, the hindwings either without or almost 

 without orange lunules, Plebeius aim/ronnoxion, etc., were particularly 

 noticeable. Hesperids of the Hesjien'a alveiis group were quite 

 inconspicuous on the brown and darkening heads of the common 

 Yarrow [Achillea willefoUion) and apparently well protected. Plenty 

 of Antltrocera HUiiendulae were clustered on heads of Knapweed, etc., 

 and among them a few of the high mountain form of Aihcita r/eryon, 

 with an odd example of Anthrocera piirjinralis. From one head was 

 taken a very fine underside aberration of Aijriades coridon, a male, in 

 which there is no trace of any spots on the disc of all the wings, there 

 being a diminished series of submarginal dark blotches on the fore- 

 wings and very obsolescent submarginal markings on the hindwings, 

 the place of the submarginal deficiencies being largely covered by 

 almost white scaling ; the discoidal spot in the forewings was well 

 marked, that of the hindwings was a conspicuous white blotch ; the 

 white wedge mark of the hindwings was also quite conspicuous. This 

 is the form called ab. corydonis by Bergstrasser and figured on Plate 

 II., British Lepidojitera, vol. xi. (Brit. Butt., vol. iv.), J. W. Tutt, and 

 referred to and described, loc. cit. p. 85. It differs in the forewing 

 markings being somewhat less emphasised than in the figures. Mixed 

 with the "blues" were several very small specimens of Krebia 

 melampiifi, no larger than the C. sati/rion ab. unicolnf among which 

 they were sitting, an example of Aricia einnedon, a number of A;/ rot is 

 ocellina, and several Botys aerealis. On the tree trunks at the back of 

 the road-slopes were plenty of the wary Blntephria fiavicinrtata and an 

 odd specimen of (rnophos ylatirinaria. A tap on the branches of the 

 pines showed where the Satyrid was roosting, while the grass stems 

 produced Crambiis fi(rcatelliis, and one or two " plumes." I find that 

 I have a specimen of Acidalia iiuihelaria taken in this spot. What 

 perhaps was the most striking incident of the afternoon's walk, when 

 the shower began in earnest, was the assemblage of great numbers 

 of Cleoyene lutearia on the conspicuously coloured, large heads of the 

 Mountain Bistort [Polyyanuin riripannii) which grew abundantly in a 

 pasture, as it usually does in alpine pasture, by the road-side. Thousands 

 of this brilliant yellow geometer could easily have been taken. 



On July 30th some friends were intending to go over the ridge of 

 mountains facing St. Moritz, by the Fuorcla Surlej, 9,055 ft., pass 

 down into the Rosegg Valley and thence to Pontresina. As the 

 Haanen See, a spot we much wished to visit, was on their way up we 

 decided to accompany them thus far. The morning was again doubtful 

 with intermittent sun, which allowed only fair collecting as it became 

 colder with more wind. There are several ways of gettmg up to the 

 See, about 7,070 ft., which is just at the tree-limit. The path chosen 

 was that at the back of the Protestant Church in St. Moritz Bad, 

 which leads by gentle ascents in the woods to the Johannisberg, and 

 thence on the left by steep zigzags to the lake and its restaurant. 



The Haanen See is a very small affair, situated curiously on a pro- 

 jecting portion of the mountain with steep declivities on three sides. 

 Here I expected to get arsilaclie, but found the immediate neighbour- 

 hood of the lake very barren. Brenthis pales was in very small
