FEEDING LIZARDS WITH COLORED INSECTS. 28 1 



became quite tame in about a week, allowing me to rub its head 

 and body with my hand. These lizards occupied the cage with 

 Gerrhonotus infernal is until December I when they were placed 

 in a separate one. The experiments were as follows : 



LEPIDOPTERA. 



Meganostoma enrydice Boisd. December i 5, was not eaten. 



Papilio ( L&rtias] pliiletwr Linn. March 26, March 30. These 

 were not noticed and were afterward removed. The specimen 

 introduced April 2 was found dead and apparently unharmed the 

 following day. On April 7 the specimen introduced the previous 

 day was gone, and on April 8 the lizard last caught was seen 

 eating a butterfly. On April 21 a specimen was introduced and 

 only a part of the wings remained next day. However, the two 

 specimens introduced on May 4 remained in the cage two days 

 and were not eaten. 



Colias eurytheme Boisd. March 30. The specimen was not 

 noticed by the lizards and was removed next day. The two 

 that were introduced April i were gone the day following and of 

 the two introduced April 2 one was entirely eaten and only the 

 torn wings of the second remained. On May 8 one of the lizards 

 seized the specimen just introduced by the edges of the folded 

 wings and ate it slowly, often pausing to rest, but never releas- 

 ing it. 



Anosia plexippns Linn. Introduced April 2. Next day the 

 head and thorax were chewed up and one fore wing was missing. 

 Others that were introduced afterward disappeared but were not 

 seen when eaten. But on May 18 the butterfly was seized at 

 once by one of the lizards and a second lizard bit off part of a 

 wing. Between them they ate the specimen, but did not take 

 the two introduced May 25. 



Pieris occidcntalis Reakirt. April 16, was eaten. 



Grapta interrogationis Fabr. The specimen introduced April 

 27 was eaten, and those placed in the cage May 7 and May 9 

 were gone the following mornings. Probably they were also 

 eaten. 



Papilio cresphontes Cramer. April 23. This butterfly did not 

 seem to be noticed by the lizards.
