Kiley notes larvio as occurriug in July, and captures of the moths in May, June, July, and 
August, 
Food plants . — Fock or sugar maple, red maple, and the oak. Mr. llridgham found a larva in 
the third stage (10 mm. in length) on the ap])le at Providence, July 20. It is the same as that 
represented on PI. XXXI, figs. 4, 4u. He also found other larvie on chestnut, maple, beech, and 
viburnum.

This species probably ranges from the southern limits of the Hudsoniau fauna southward 
through the Appalachian and Austrorix>arian subxirovinces, and very rarely occurs in the 
'Campestrian (Colorado).

‘ H. viridescens (Walk.) is simply the female of H. hiunda s, as Mr. A. E. Butler kindly iuforms mo, and as had 
previously been determined by Mr. Grote. It is mentioned l .v xVIr. Grace, under the name above, with the remark: 
‘‘I do not agree with Messrs. Grote and Robinson in regarding this insect as synonymous with C. {Ucterocamx)a) 
hiundaiaP 
H. dardania Grace, Biologia CeTitrali-Americaua,x>. 237, from Jalapa, Mexico, appears by the figure to be very 
near H. biundata, and may prove to bo a variety of it. 
H. alector Grace, (l.c., p.238) also, judging by the colored figure, seems to he very near the 9 of H. biundata, 
rather thaiipw?rcrcrt G. and R.
