1 The larvae of this species were so abundant in Albany during the summer as to 

 prove a serious annoyance, by nearly defoliating many of the shade trees. At the 

 time when they were seeking suitable places for their transformation, a person could 

 scarcely walk a block without treading several of them under foot. 



2 Other colonies of this larva were found on willows within nests composed of sev 

 eral leaves spun together. The last of February, within a box which had been stand 

 ing in a moderately warm room, the moths commenced emerging from the slight 

 cocoons which they had constructed between the leaves at the bottom of the breeding 

 cage. The insect seems unusually hardy (unlike L. crispata), for the number of 

 imagines disclosed proved nearly equal to that of the larvae which had been secured. 

 They continued to emerge during the month of March, and all, it was observed, 

 escaped from the cocoons in the day time. 



3 A colony of about twenty of these larvae, measuring four-tenths of an inch in 

 length, was found July 15th on Populus tremuloides. They were reared to pupae, 

 from which three imagines were disclosed between the 17th and 23d of September, 

 and others the following Spring.
