ings just behind the head, on the third abdominal segment and near 
the posterior extremity. The markings vary much in different 
larvae, there usually being a broad, reddish brown area, frequently | 
forked anteriorly, just behind the head and extending to the first 
abdominal segment and an irregularly expanded area on the third 
abdominal segment. The reddish markings at the posterior ex- 
tremity are more variable, sometimes being rudimentary. The full 
grown larva is about an inch and a half long, has a rather small 
head, with the body increasing in size to the fourth abdominal 
segment, from which it tapers; the posterior extremity being slender, — 
usually elevated and the last pair of abdominal legs extending 
behind as two small divergent processes. 
Pupa. The pupa is rather short, thick, stout, about 34 of an 
inch long and with a pair of short, stout, angulate appendages at 
the posterior extremity. 
Life history. This species, according to Dr Packard, deposits 
eggs at Brunswick, Me., as early as July 3, the larvae hatching

a time on the under side of the leaf, at first eating away small, 
irregular patches. The first stage lasts about nine days, the second 
probably four or five days. Full growth is attained in about a 
month, though belated individuals may occur as late as the end 
of September. The larva, when annoyed, has a habit of jerking 
its head suddenly from side to side as though trying to drive 
away some assailant. This species appears to live by preference © 
on sugar maple, red maple and oak, though it has also been taken 
on apple, chestnut, beech and viburnum. Miss Patch records beech 
as a preferred food plant in Maine. 
Distribution. This insect appears to have a wide distribution, 
it having been recorded from Florida and Georgia, north and east- 
ward through Maine to St John’s Bluff and westward as far as 
Fort Collins, Col. Dr Packard states tat it is a rare species in™ 
Colorado. 
Natural enemies. These caterpillars are subject to attack by 
a number of predaceous forms. Miss Patch states that in Maine 
the fiery ground beetle, Calosoma calidum Fabr., was very 
abundant about the base of infested trees and that one of the soldier 
bugs, Podisus modestus Dall., was quite active in destroy- 
ing the pests. 
Remedial measures. The discussion of remedial measures 
given in our account of the green striped maple worm, Anisota 
rubicunda Fabr., would apply with equal force to this species.
