of their food plant, occasionally biting on down from the top 

 until the pedicel is partly consumed. Sometimes they start in 

 on a seed-pod near the middle and eat it nearly through and 

 then finish one side on down to the stalk. Only once did I 

 find one cutting a leaf. At rest they often assume a sphinx-like 

 attitude. In confinement, when one caterpillar has suspended 

 itself and pupated, another will frequently select the same spot 

 and spin its "button' over that of the first, attaching its 

 " chest loop " to the back of the first pupa. I have observed 

 this also with larvae of Papilio crcsphontes in confinement. The 

 prolonged pointed beak of the pupa of genii tia extends so far 

 beyond the ' ' chest loop ' ' that the chrysalis has an uneasy ap- 

 pearance, as though about to fall out. The peculiar, jointless, 

 double-pointed, yellowish brown pupa has been well described 

 by Mr. Edwards, and after him by Mr. Scudder. In the works 

 of both of these gentlemen the full stages of the larvae are also 

 given at length. 



In May, 1898, I had nine larvae of genutia in one breeding 

 cage : all pupated and have remained apparently lifeless ever 

 since. On March 28, 1900, I found a freshly emerged male 

 hanging in the cage near an empty pupa skin, and two others 

 have since emerged, and at the present writing others show 

 signs of activity. This is quite a long period for so many 

 pupae to remain over. I have often had one or two out of a 

 brood of asterias or tiirnus or ajax to remain over two seasons, 

 but never quite so wholesale a delay.

Since the two lists previously published in the ENT. NEWS, 

 vol. vi, p. 309, vol. vii, p. 234, many species have been added, 

 but it has been deemed advisable to await the result of thor- 

 ough collecting before publishing another specific list. 



Some notes pertaining to the more unusual species may not 

 be amiss in the meantime, and with this fact in view the fol- 

 lowing are submitted :
