66 THE entomologist's record. 



viatKs phereteH, Brenthh pales, B. euphrosi/ne, B. selcne, B. auiathusia, 

 Melitaea ci/nt/iia, M. matura var. icnlfensboyeri, Poutia calUdice, Coeno- 

 nyinpha airania var. daridniana, C. sati/rion, Af/lais iirticae, Pieris 

 rapae, with various forms of Erehia, many of which, alas ! still need 

 identification, owing to necessity decreeing they must be left behind 

 in Switzerland, swarmed always on higher rhododendron covered slopes 

 right up to the summit, some 8,000ft. — and in fields equally beloved 

 of butterflies around the Upper and Lower Glaciers, and in the valley 

 of the Liitschine. 



Loeuia [Chrysophaniis) dorilis g I found unce in fields between 

 Baugy and Vevey La Tour, August 18th, 1914 ; although there were a 

 few J s at Charpigny during both seasons. 



Loiveia {Cliri/wplianiis) alciphron var. gordius was never really 

 plentiful, even at Yernayaz or around La.Batiaz; and Riniiicia phlaeas 

 I saw not at all ! male nor female. 



The seasons were, however, wet and sunless, except, perhaps, mid- 

 June and part of August, 1914 ; as, I believe, was the preceding one, 

 1912. 



One feels inclined to think that want of sun tends to produce 

 scarcity to a more marked degree in particularly bright-coloured races, 

 such as Chrysophaniis, than in darker ones, such as the genus Eiebia, 

 species of which were numerous in some places, viz., aethinps and 

 melawpus from Villars-Bretaye, and at Grindelwald, July, 1914 ; oeme 

 and manto (not so common) above Upper Grindelwald Glacier; 

 tyndarus, lappona (with ab. polltix), (jorye, and styyne on Faulhorn, 

 August 1st, 1914 ; medusa and var, hlppomedusa between Bex and 

 Charpigny, May-June, 1918-14 ; oeme on Dent du Midi with ceto, 

 ligea, and higher, euryale, July, 1914; ceto (perhaps not very 

 abundant) at Zermatt, June, 1914, etc. ; Satyrus herutione swarming 

 with S. cordula all June and July, both years, at Charpigny, and in 

 vineyards above Martigny ; most forms of the genus Pararye (Char- 

 pigny, Lac Champex, Grindelwald, etc.); Coenonympha, most forms at 

 several places, including the rarer tiphon, W. of St. Triphon Marsh, 

 etc., and in lighter-coloured races as the genus Pieris, usual forms of 

 which were plentiful everywhere, except daplidice, Anthocharis helia 

 var. simplonia, smaller race than some, but not quite alpine, nearly 

 profuse at Zermatt in early June, 1914; and var. jiavidior fairly 

 common along the banks of the Gryonne (near Bex), 1914 — odd 

 specimens spreading to the Charpigny rock. May, 1913, and Parnas- 

 sius apollo, at many places most abundant (Finhaut, Champery, 

 Grindelwald, etc.), although neither delius nor mnemosyne came under 

 ray notice. 



This opinion is strengthened from the fact that on my return to 

 England, at the end of August, 1914, Bumicia phlaeas was swarming 

 to mid-September on the Surrey Downs between Guildford and 

 Newlands Corner, the summer having been an exceptionally dry one ! 

 Of course, Bumicia phlaeas is admittedly a commoner species in 

 England than in Switzerland. It must, therefore, be with reservation 

 that one argues — although one does argue it — that the theory of the 

 sun tending to produce brilliant forms, and lack of it only dark, or 

 lighter ones, holds good in this case. Especially, when, on the other 

 hand, such highly-coloured butterflies ascertain species of Lycaenidae : 

 Agriades thetis (bellargus), including ab. ? ceronus, Polyommatus hylas,
