t Note. — The fact, wh. has always seemed probable, that Ctimilla is at 

 least partially double-brooded, is now placed beyond doubt. Mr. Sloper reared a 

 number of larvte from the 1st brood at Glion in 1901, some in captivity, some 

 placed out of doors on the fd. pit. Although those in captivity were removed to 

 Zermatt, they emerged in August, and, on returning to (ilion in September, at 

 least one empty pupa-case was found on the plant on which he had placed the 

 other larvse on leaving for Zermatt.
