. The butterflies of the eastern United States and Canada [microform] : with special reference to New England. Butterflies; Butterflies; Papillons; Papillons. 1214 TIIK BUrrKKFLIKS OF NKW EX(;LANI>. I-' â A .i' i ? -t' 'V,, y. Mlaoellaneotis. The male of thie spcciei Uhh a very faint l)ut pleasant cmIop, <lifficiilt to detect. I hiive Homctinies <lone so, but at other times have been unable to perucivc it, on riil»binj^ tliesciles of the upper surface of the wings and immediately smelling the fingers. It comes from the scat- tered androconia. Dr. Dimmock tried some experiments (Psyche, ii: 21) with the imago of this insect, to sec how it would endure breathing certain gases. Kx- posed for periods varying from one to thirty minutes in an atmosphere of carlionie monoxide, motion cciined in from eight seconds to a minute, was resumed again in from ten seconds to five minutes after removal, and became active in from twenty secondH to three minute»v the differences, was not noted. "They all rubbe<l their probosees al)out their legs while recovering, and several , . exhibited a slight tendency toward paralysis of the posterior limbs during recovery." Immersed in hydrogen, the butterfly was rendered motiiink'ss in half a minute, and remaining five minutes in the gas, began to moxe at tiic end of eight minutes after removal, and to fly â¢'in a weak manner" in two more minutes. One placed in a mixture of eighty partw of iiydrogen and twenty of oxygen, and one in equal |)arts of eacli showed no signw of weakness at tlie end of lialf an liour. Mr. Davis pierced some chrysalids of this species with pins, but tliey hatciied, nevertheless, one of tiicm emerging with the pin through its thorax, as if impaled for tiie caiiiiiet. Many other species, however, ex- hibit similar tenacity of life. Parasites. An account of tlie insect enemies of this destructive but- terfly may well begin with Europe, where the pest originated.
