IJiley iioti's liirvii* :is occurring in July, and captnrcs of the. moths in May, June, Jnly, iuid 

 August. 



Food plants. — Hock or sugar maple, red uiajile. and tlie oak. Mr. IJridgliam fonnd a larva in 

 the third stage (10 mm. in length) on the a])iile at Providence, July 20. It is the same as that

This species probably ranges from the sonthern limits of the Hudsonian fanna southward 

 through the Ai>palachian and Austroriparian subprovinces, and very rarely occurs in the 

 Campestrian (Cohn-ado).

Moth. — Five S and six $ . Antennse of <5 well pectinated on the basal two-third.s, filiform at 

 the end; the body and wings ash gray, often greenish ash, the wings more or less olive sea-green 

 in tint. Head ash-gray, sometimes greenish on top, ashen in front; palpi wide, bushy, ashen, 

 black on the sides; third joint thick, distinct, shorter than in uuftiritta. Thorax ashen, greeni.sh 

 on the sides at the insertion of the wings, sometimes entirely olive greenish, except behind 

 insertion of the fore wings; on front edge of the thorax a dark brown transverse stripe; a 

 more distinct transverse stripe behind, and the hi.ider edges of the tegulie dusky; between the 



.' B. viridescens (Walk.) is simply the female of if. iiundt. :, as Mr. A. E. Butler kindly informs me, and as had 

 previously been determined by Mr. Grote. It is mentioned \ \ Mr. Druce. under the name above, with the remark: 

 "I do not agree with Messrs. Grote and Eobinson in regarding this insect as synonymous with C. {Heterocampa) 

 biundata." 



H. dardania Dnice, Bioiogia Centrali-.\mcricaua. ji. 237. from .Jalapa, Mexico, appears by the figure to be very 

 near H. biundata, and may prove to be a variety of it. 



H. alpclor Druce, (1. <•.. p 238) also, judging by the colored ligure, seems to be very near the 9 of H. binudata.
