Bimilixr to that of Incompletes miyht have arisen by the further evolu- 

 tion of these points ; and had it done so its origin would have been 

 entirely separate from that in Incompletce, and yet might have been 

 indistinguishable from them. The ground for surprise in these matters 

 is, hovpever, after all, not that there are so frequent cases of similar 

 structures having independent origins, but that we meet with com- 

 paratively so few, at any rate, so few that we are able to be sure about. 



The imagines emerged at various times up to the middle of 

 September. 



The eggs are yellow, oval, with the ends more square and truncate 

 than usual in Geometrce, but less so than is usual in Cramhus. The 

 length is about 0"65 mm., the surface is wrinkled with a hexagonal 

 netting, the ribs forming which are rather broad.

LEPIDOPTERA OF THE ITALIAN LAKES IN OCTOBER. 

 Br A. HUGH JONES, F.E.S. 



I spent the middle of October on the Italian lakes, a month that 

 one perhaps would not fix upon for an entomological excursion, yet in 

 other respects a more delightful time could not be selected, if favoured 

 with the conditions such as I experienced : brilliant, warm, sunny 

 days, cool nights, and not overcrowded hotels. I arrived at Menaggio, 

 on lake Como on October 11th, a perfect day, and whilst having 

 luncheon in the garden of the hotel my attention was drawn to the 

 numerous butterflies, chiefly the two small common " whites," also 

 Lyccena hcetica and Arqynnis Latonia ,\\]i\c\i were attracted to the flowers 

 still in luxuriant bloom. After a short stay at Cadenabbia I started 

 for Stresa, at the southern extremity of Lago Maggiore. At Stresa I 

 remained a week. I had expected among the moths good results with 

 the electric light. A room constructed outside the Hotel des lies 

 Borromees, where I was stopping, was very complete in its arrange- 

 ments for this purpose, being surrounded on all sides by glass. Only 

 on one occasion, however, did the temperature rise suiEciently for 

 moths to fly, and on that occasion I saw Margarodes unionalis, two of 

 which were captured. The most abundant butterfly was Lyccena hoetica, 

 which flew over the grass and flowers in the gardens of the hotel near the 

 lake side, and the commonest moth was Plusia gamma. A visit to the 

 town of Orta, charmingly situated on the lake of that name, resulted 

 in my adding another butterfly, viz., Apatura Ilia, to my list.
