Family Lasiocampidae. 
I have discussed a number of examples of this family showing the 
range of modification of these highly specialized larvae (See Ann. 
N. Y. acad. sci., vol. 8, p. 229, and Journ. 1ST. Y. ent. soc., vol. 3, p. 
23). The abdominal tubercles were deduced by analogy with the 
Eupterotidae and the thoracic ones were not mentioned, as I could 
not make them out. Moreover, my description of stage I of Clisi¬ 
ocampa fragilis is erroneous. It will be found corrected in Psyche 
(vol. 7, p. 259). I will reserve for a future opportunity the descrip¬ 
tion of the numerous forms assumed by the larvae of this most inter¬ 
esting group, and will treat here only of the single generalized 
species which I have been able to find which confirms the testimony 
from stage I of Clisiocampa and Tolype.

The arrangement of warts is as in Clisiocampa, but the confusing 
secondary ones on the anterior part of the segments are not present 
here. On the abdomen, v is smaller than iv, and all except i and 
vi are greatly reduced. These two warts alone persist in the adult 
larva (i. e., i and vi, not ii and v as I stated in my first paper, Ann. 
N. Y. acad. sci., vol. 8, p. 229). On the thorax there are three 
warts above the stigmatal wart, tlie middle (?) one posterior to the
