MOTHS AND BUTTERFLIES. 
selected for this purpose were usually the low bushes not over a foot 
or two high, and three or four of the light green larvae were some¬ 
times seen quietly feeding on one bush. Toward evening the butter¬ 
flies collected about the paw paw bushes and settled for the night 
clinging to the under side of the leaves, where early in the morning 
they might be taken with the fingers. Many of the transfers of this 
species for this work have been made from butterflies taken in south¬ 
ern Ohio. It is not difficult to rear this insect in captivity. Some 
of the chrysalides are light green and others brown, and are translu¬ 
cent until the butterfly begins,to form beneath the outer shell. 
Several very beautiful species closely allied to Papilio ajax are 
natives of Central and South America. In Colombia my brothers 
took some of the largest and finest of the group, specimens of which 
now adorn our cabinets.

One of our largest and most strikingly colored butterflies is 
Papilio cresphontes , a very good idea of which may be had by refer¬ 
ence to the transfer. 
The contrast between the upper and under side of the insect is 
very marked, and when oil the wing the butterfly looks black at one 
moment and yellow at another, according to which side of the wings 
is seen by the observers. The home of this fine butterfly is in the 
southern and western states, but it is sometimes to be found in 
the north and several specimens have been taken near my home in 
Massachusetts within the last few years. It is abundant in southern 
Illinois in July, and is not at all rare in southern Ohio at that season 
of the year. On looking out of the car window as the train stopped for
