E. delphinii Bsd. (= strigata Bsd., quercicola H.-S., tardigrada Clem., monitor Pack., ferruginea Pack., 
bifida Pack., excisa Wkr., mira Dyar) (164 i). The nomenclatural type is the eastern race. Hindwing dark 
brown, not much lighter than the forewing; the green on the forewing divided into a subbasal and subapical 
spot, each followed by red colour. — In querceti H.-Schdff. (164 i) the lower spot is split. — interjecta Dyar shows 
the two spots connected by a series of small green spots which in — viridiclava Wkr. (164 k) are united into a 
complete band, while in — elliottii Pears, they almost or entirely fill up the cellular space. The western race is 
paenulata Clem. (164 k), with light yellow hindwings sometimes feebly strewn with brown outside; the green 
area of the forewing is somewhat smaller, so that a broad dark margin and a more or less distinct discal spot 
remain. Clermont, Massachusetts, New York, Maryland, Virginia, North Carolina. The form — incisa Harv. 
has a somewhat more extensive green, therefore narrow dark margins, and very light hindwings, Expanse of 
wings: <$ 15—24, $ 24—30 mm. Wisconsin, Iowa, Nebraska, Florida, Missouri, Texas. The elliptical larva is 
flat, green or reddish, the horns short, with yellow subdorsal lines and dark undulating dorsal and lateral lines, 
but the ornamentation most variable. On trees and shrubs.
