I am familiar with the larva, as I have found it at Keene Valley and 

 Rhinebeck, New York, and Fort Lee, New Jersey. My larvae had six 

 stages, not five, as given by Mr. Fyles. The widths of head were .35,-5, 

 .8, 1.3 to 1.45, 2 to 2.2, 2.7 to 3 mm. The full-grown larva corre- 

 sponds with his description, but occasionally a striking variety occurs, in 

 which the incisures dorsally are banded with pale yellow, somewhat in 

 the manner of Ecpanthcria scribonia. 



To Mr. Fyles's second proposition I would positively dissent : 



1. Walker knew ciinea and separated it by a good character from 

 congiua. 



2. Southern specimens of cunca are larger than the dwarfed ones 

 from the north with which Mr. Fyles is familiar, and it is absurd to sup- 

 pose that after giving an account of the life-history of the webworm, Dr. 

 Riley should have figured only moths coming from a black, ground-feed- 

 ing larva (coiigriia). Besides, Dr. Riley's moths are still in the National 

 Museum and are structurally Hyphantria, while, previous to my taking 

 charge of the collection, the Museum had but two specimens of congrua 

 (Dr. Riley's collection had none), neither of which could have served 

 for the published figures of cutiea. 



3. In markings, ainea and congrua may be practically alike. The 

 differences reside principally in the structural characters of the number 

 of spurs on the hind tibiae and the wing shape. 



4. Mr. Saunders's description of the larva of cnnea as black and feed- 

 ing on the ground, was simply due to a misidentification of the imago. 



Therefore the synonymy of this species may be : 



H. cunea, Dru.

 picnctata. Fitch.
