This season I have seen some peculiarities in rearing Papilio cresphontes that seem worth noting. I had at one time four of the larvæ in a cage of three different broods. The two older ones changed to chrysalids June 29th; one from the top of the box with the head down, number two on the side with head up. Number three pupated July 11th, on the side of the box, head up; number four changed July 14th, suspended from the top the same as number one, all of them at an angle with the object to which they were attached, as is usual with Papilios.
