Rhodocera rhamni, Polyommatus Dorilis, LyecEtia hatica (generally distributed, but 

 never common), argiades, Avion (one specimen only), Agestis, Adonis, Argiolus, 

 Corydon, and Alexis; Vanessa c-album, urticcB, Antiopa, and Atalanta, occwred 

 sparingly; Melitcea Dia and Parthenie ; Argynnis Lathonia, Adippe, Erehia Tyn- 

 darus, Satyrus Hermione, Pararge Mcera, Megcera, and Mgeria were all more or 

 less common ; a few specimens of Syrichthus alveus, Hesperia comma and linea, 

 completed the list of butterflies. 



Callimorpha Hera was not uncommon flying in the bright sunshine ; and at 

 rest on rocks, Qnophos obfuscaria, Cidaria immanata, and Acidalia degeneraria 

 were to be met with occasionally. 



On one warm evening, at the lamp outside the hotel at Picrrefitte, I noticed the 

 following : — Selenia lunaria, Rumia cratcegata, Boarmia rhomboidaria, Heliophobus 

 papillaris, Apamea Dumeriiii (Duponchel), and Steganias permutaria (Iliibner). 



On the stone walls in the valley of Lesponne, I found Folia clii and Bryopliila 

 glandifera, and in the crevices, suspended in some numbers, the pupse of J^anessa 

 c-album, and occasionally those of Vanessa Atalanta and Pararge Megmra. 



On the 7th September, I ascended, from the village of Gripp, the Pic du Midi 

 de Bigorre (9439 ft. above the sea). The path is a good one to tlie summit, and the 

 ascent an extremely easy one. On leaving the valley (about 5000 ft.), butterflies, 

 including Parnassius Apollo, Argynnis Lathonia, and Lycmna buetica, were somewhat 

 numerous, but they very soon diminished in numbers. At 6000 ft. I noticed but 

 one species, viz., Erebia Manto, much worn, and a solitary full-grown larva of 

 Chaerocampa porcellus. Beyond this elevation all insect life seemed to cease. 



Although somewhat disappointed from an entomological point of view, in 

 other respects the excursion was an enjoyable one, for on the following morning I 

 witnessed a beautiful sunrise from the top of a mountain, which, from its isolated 

 position, afPords one of the grandest views in the Pyrenees. 



From the summit, as far as the eye could reach, scarcely a vestige of snow was 

 to be seen in any direction, except on the highest mountains ; two days later (12th 

 Septembei"), however, the weather became very unsettled, and a complete change 

 came over the scene, the higher slopes of all the mountains being then completely 

 covered with a mantle of snow. 



Continuous rain falling in the valleys rendered further collecting out of the 

 question. — A. H. Jones, Shrublands, Eltham, Kent : 17^A November, 1882. 



On the variation of the sizes of Lepidopterous eggs laid by the same female, and 

 other notes. — Some time ago I corresponded with Mr. W. H. Harwood on the question 

 as to the eggs of Macro- Lepidoptera\&v jing in size, and he mentioned instances, chiefly 

 among the " Prominents," where he had observed some difference in the size of eggs 

 laid by the same female ; this difference he had been accustomed to associate with 

 the sex of the future imago, the larger eggs being expected to result in female moths, 

 the smaller in male, but I am not aware that he had tested this theory very exactly : 

 he also furnished me with the experience of another entomologist, who had noted 

 that the first-laid eggs of Hawkmoths are larger than those which follow. These 

 observations interested me much, and I meant to pursue them with some care, but 

 so far I have not done what I wished, and all I can now add is this — last June I 

 captured an impregnated female of Sm. populi, and, by shutting her up in a large
