Bookham, with specimens of the two races of Z. chlot'ocepliala, 

 Hoff., from Furley and Plumstead for comparison. 



Mr. Tutt gave a lengthy and interesting account of what 

 had been seen by Dr. Chapman and himself during a 

 holiday tour in the Upper Dora and Cogne Valleys in Pied- 

 mont. He said that the main object of his journey was to see 

 the rarer British species of Rhopalocera in their really native 

 haunts. In this object he had been most successful for Carte- 

 rocephaliis palcEinoii, Pall,, and Thecla primi \wcx& perhaps the 

 only species he had not now seen, the rest being in one place 

 or another absolutely in profusion, A most remarkable cir- 

 cumstance to him was that so many species should be out at 

 one and the same time, some species seemed to have a con- 

 tinuous brood lasting throughout the summer and not to 

 emerge at a definite period as in our own northern clime. In 

 one valley alone, quite a hundred species of butterflies could 

 probably have been taken. Papilio podalirius^ L., was com- 

 monly observed at pools in the road, and wherever there was 

 moisture of any kind, even in the shade, there insects swarmed. 

 During the whole month he was away, he experienced no 

 wet, the weather was simply glorious and most propitious for 

 insect life. In a valley at the base of Mont Blanc, the genus 

 Erebia was most abundant, but he only saw two fine specimens 

 of Erebia cgthiops, Esp. To call some of the Erebias 

 " browns" was certainly a misnomer, many species being most 

 elegantly shot with iridescent colours. Parnassms apollo, L., 

 was in abundance on all the alpine slopes. The larvae of 

 Papilio inachaon, L., occurred now and again, and imagines 

 were occasionally seen. The " hedges " were low walls of 

 stone, which had become covered with a close growth of 

 saxifrage, and this, when in blossom, formed one of the 

 best natural attractions for insects which he had ever seen. 

 Gonopteryx rhanini, L., was common, and Dr. Chapman also 

 saw specimens of G. cleopatra, L. in Savoy. The " whites " 

 were excessively abundant, Pieris daplidice, L., being common 

 in many places, especially in the Aosta valley. It was 

 certainly most conspicuous on the wing, and he failed to 

 understand how an ordinary observer could for a moment 

 confuse this species with any other " white " when flying. 

 The higher slopes of the mountains were the haunts of in- 

 numerable imagines of the genera Argynnis and Erebia. In 

 the Cogne Valley A. paphia, L., was taken together with a 

 very fine specimen of the var. valesina, Esp. A. niobe, L., 

 was in enormous quantities, but very local. He noticed all 

 the British species of Alelitcea, including M. cinxia, L., and
