sons on the top of a gate post at Wimbledon about 8 a.m. As it was a particularly 

 fine specimen he brought it up to me at Lloyd's. At the time I received it (about 

 11 a.m ) both of its antenna? wei'e waving about freely ; sufficiently so to be of 

 interest to many of my friends in the " room." Each antenna seemed to work 

 quite irrespectively of the other, and one would often be still while the other moved. 

 Their movements were not in any way rhythmical, the long basal joint of the an- 

 tenna would be extended and retracted, and quite as a separate movement the rest 

 of the joints would move to and fro from their fulcrum at the apex of the first 

 joint. The lamellar joints of the club would also move separately ; the apical joints 

 of the antennae- were very sensitive, and the antennas would retreat rapidly on their 

 being touched ; this condition went on without interruption till 3.40 p.m., when 

 I had to leave to catch a train. I put the head into a little flat cardboard pen bos, 

 packing it in with blotting paper in such a way as I thought would allow the an- 

 tenna? free play ; on opening the box, however, after I had got into the train I found 

 that one of the antenna? had got against the side of the box, and from that moment 

 it never moved again. The other, however, went on as before till about 4.30 p.m., 

 when it began to droop, and would only recommence movement on its own account 

 on being touched ; at 5 p.m. all movement had practically ceased, and the organ on 

 being lifted fell back to its original position. An interesting point in this matter 

 was that from the time I received it all the other appendages of the head were 

 motionless, in fact, they were already rigorous, and sprang back at once to position 

 on being extended. The sensitiveness to touch of the apex of the antenna? existed 

 to the last observable free movements. There can be little doubt T think that reflex 

 muscular action alone would not account for the movement noticed, the nerve 

 centres could not have been dead, and the absence of movement in the other organs 

 would suggest that the antenna) have separate nerve centres from those which feed 

 the other cephalic appendages. — Edward Saunders, St. Ann's, Woking : June

Lepidoptera in the Montreux district.— From May 26th to June 6th, 1902, I 

 was at Montreux, on the Lake of Geneva, and devoted part of my time to collecting 

 Rhopalocera. The district worked was that between the village of Blonny on the 

 north, and Aigle (about six miles up the Rhone Valley from the Lake) on the south. 



Such species as Leucophasia sinapis, Euchloe card amines, Vanessa Io, Cceno- 

 nympha Pamphilus, Thecla ruhi, Lyccena Alms (minima), Syrichthus malva, and 

 Nisoniades Tages were met with almost everywhere ; while Nemeobius Lucina and 

 Hesperia sylvanus were common locally. 



I saw about half a dozen Papilio Podalirius, but only one of those captured 

 was at all perfect. Aporia cratagi, $ s, were out in some force by June 5th. Colias 

 Hyale was to be seen fairly frequently, but I did not come across any Colias F.dusa, 

 except one var. Helice, taken at Blonay on May 31st, which is in first rate 

 condition. 



Of the Fritillaries I took Argynnis Selene (one, worn), A. Dia (two, worn), 

 A. Euphrosyne, Melitcea auriuia, M. Athaliu, and M. Cinxia. The last four 

 species all in perfect condition. 



The Vanessidce were a good deal in evidence, V. Io and V. cardui heading the
