MEMOIRS OF THE NATIONAL ACADEMY OF SCIENCES. 
Larva , — Body noctuiform, tapering toward eacli end; smooth, entirely unarmed. Head 
rounded, smooth, with a black stripe on each side. Body with a subdorsal yellow line on each 
side of back, otherwise pale green, or Muth several dorsal pink patches. 
Freshly hatched larva with a large round head, wider than the elongated body, which tapers 
toward the end; segments smootli, sutures deeply impressed; glandular hairs short, minute, 
ending in three prongs; no lines or spots. 
Cocoon . — Slight and thin, spun between leaves. 
Pupa. — Flattened, oval, rounded obtusely at each end; cremaster obsolete, with no traces of 
spines. Color darker than usual. 
Geographical distribution . — The species range throughout, the Appalachian Subproviuce into 
the Hudsonian fauna, and westward occur in the Cainpestrian Subprovince. None have yet been 
found south of the thirty-second parallel of latitude, either on the Atlantic or Pacific slopes of the 
continent. The genus also extends over Em'oi)e, being represented by a single species {G. creuata) 
which inhabits England and Europe, extending eastward into central Russia and doubtfully into 
Spain. One si^ecies (C. Uturata Walk.) inhabits Silhet and India (Madras). 
It is divided into two sections, as follows: 
SYNOnSIS OF THE SPECIES. 
I. Thorax with no tuft: in hiufl wings the two hranches of the subcostal vein short, dark ash-gray, with a 
dull luteoiis median band ou fore wings G. septentrionis 
Paler gray, median baud on fore wings clearer and paler clay-yellow G. UTighUi 
II.^Thorax usually with atult; head rather small; palpi feeble; the two branches of the subcostal vein of 
hind wings long. 
Mouse color; no discal si>ots; antemue almost plumose G. lintneri 
A dorsal thoracic tuft, and a bright, distinct basal and discal spot G. sevara. 
Section I. 
The differences between this section and the second are brought out iu the descrijttiou of the 
latter.

Motli (0 5, 2 $ ). — Head, thorax, and abdomen ash-gray, varying iu being darker or paler. 
Fore wings usually lighter thau the thorax, with a short basal dark lino composed of two scallo])S, 
■one on the subcostal vein, the other situated in the median interspace, iuclosiiig and bordered 
with whitish gray, beyond which is a broad dark difi'u.se baud crossing the wing; the third or
