64 THE entomologist's record. 



occasional Pleheius orhituluK was taken also with a few Anthrocera 

 (Xj/i/aena) e.ridans, whilst I took a single quite fresh Brenthis euphru- 

 Ki/nc. By the tiny little tarn, at the back of which the glacier rests, no 

 insects at all were seen, though on the scree? on the Canigou side one 

 or two Krebiac were noticed, but quite out of reach. The next day we 

 worked the gully already referred to, with considerable success so far 

 as'/<A lefebvrei is concerned. It was the rocky bed of a winter stream, 

 now quite dry, leading up to the Barbet path, and on each side of it 

 was a rough mountain pasture, on the difficult slopes of which I took 

 more than one Uepialnx pyrenaicus. It was here I took my second 

 pair in coitii, but it was not until another day that I was able to verify 

 my first observation on the curious method of mating as alread}^ 

 recorded in this journal. E. lefebcrei was fairly common, though the 

 females were as yet much less in evidence than the males. 



After this we spent a couple of days on the other side (south-west) 

 of Canigou, going along the usual easy path to the summit, and our 

 captures were but few. Pleheius orbitiiliia was taken very sparingly ; 

 it was evidently barely on the wing. The Canigou form is different in 

 some respects from any other races that I know, but I will go into this 

 question later on. ('olios phicomone was not uncommon ; one male is 

 very yellow and clear, but generally they were dusted with grey fairly 

 heavily, whilst the females are also very grey. Pieris callidice was by 

 no means common, and my best specimen was taken on this first day. 

 It seems probable that in this latitude they were going over. One or 

 two Argynnids were captured, Prcnthis pales being the commonest and 

 quite typical, whilst a perfectly fresh female of hsoria lathonia 

 fell to my net, in which the suffused basal areas of both wings are 

 extraordinarily bronzy-green, that in the secondaries extends all 

 over the cell and in both cases the golden greenish colour is 

 exceptionally bright. Bient/iis euphrosj/ue also occurred sparingly. 

 Among the Heteruveva that I captured on these days Anthrocera 

 {Zi/naena) exulans was the commonest. Remembering that I bad 

 taken Anthrocera antlnjllidis just over the Yignemale Pass in a 

 previous year, I .worked hard and kept a keen look out for it all 

 the time, but did not see a single specimen. Anthrocera e.ndaus, 

 however, was common all the time of my visit, but it was the only 

 species seen near the summit or on the little pasture on which the 

 Chalet Hotel is situated. I cannot say that these two days' record 

 satisfied us, but though bright it was not very warm and early mists 

 rolled up so that we had to return home fair!}' early. Of course, we 

 ascended to the hut on the Pic itself, where we had our lunch on one 

 of the days, but it is a vast mass of stones and for some distance before 

 ihe summit, scarcely any insects were seen, except one or two that 

 were blown across. The following morning we took a walk down- 

 wards along the route towards Amelie-les-Bains, obtaining most 

 beautiful views of the lowlands around. As we descended slightly on 

 to the rich, but small, pastures below the hotel, a new capture was 

 made that puzzled us at first. It was a form of Erebia ti/iularas 

 perhaps nearest ab. droiims, but the pale tawny patch on the 

 pi-imaries was very large and so bright that we could not think what 

 form it was. It was by no means rare and all of both sexes weie 

 equally bright in coloration. I shall, however, refer to this later on. 

 As we descended through the fir woods it soon became evident that
