Average length 17 mm.; greatest width 5 mm. 



The larvae of this species were collected from maple, but 

 they are found on other kinds of trees. They are two inches 

 or more in length, dark grayish brown and the mesothorax 

 somewhat swollen at the sides. They pupate by attaching 

 themselves to the leaves with a few threads of silk and then 

 folding the leaf over, or attaching another leaf to it with the 

 silk. These threads of silk do not form a cocoon. The pupa 

 fastens itself to the silk by means of the cremastral hooks. The 

 larvae are found in July and pupate early in August.

 the caudal margin ; abdominal segments 1 to 8 punctate, the 

 tenth segment irregularly rugose ; furrow on the dorsum be- 

 tween the ninth and tenth segments distinct, the caudal margin 

 coarsely toothed, the lateral extensions never reaching to the base 

 of the cremaster ; cremaster longer than the tenth segment, bear- 

 ing two very stout spines at the distal end and slender hooked
