NOTES ON THE LARVAL STAGES OF SAMIA CYNTHIA. 



BY CAROLINE G. SOULE, BROOKLINE, MASS. 



The eggs of Cynthia^ except a very 

 few, did not turn green before hatching. 

 Those laid first, loth May, hatched on 

 31st May, giving 21 days for the egg- 

 period; but those laid last, i8th May, 

 hatched on 3d June, giving 16 days for 

 this period. 



The larvae ate very little till the 

 middle of the second day, and did not 

 eat the egg-shell at all, unless the}' ate 

 the bits removed to let them out. 



When very young they seemed to be 

 troubled by tiie excrement, which clung 



to the anal shield, instead of dropping 

 in the usual manner, and the larvae had 

 a way of seizing the excreta with their 

 mouths, pulling them free, atid then 

 giving them a quick jerk which threw 

 them over the edge of the leaf. There 

 was a little silk visible all through the 

 first stage, where the larvae moved. 



About 120 eggs I gave away, of the 

 remaining 221 only two failed to hatch. 



I gave most of the larvae tulip-tree 

 {Lirzode?zdron tulipifera)^ leaves,. 

 which they ate eagerly.
