G. vivida Dyar (28 c) is somewhat similar to baileyi, with brighter markings, the forewing whitish- vivida. 
grey particularly in the basal area and the maculae, as well as subterminally, otherwise irrorated with blackish. 
Hindwing blackish-brown. Expanse of wings: 37 mm. British Columbia. 
G. viridipallens Grt. (28 d) is light greyish-green with double undulate, not crenulate transverse lines, viridipul- 
a blackish faded median shade, the maculae surrounded by black, the ring-macula being renifoim and above lem 
and below open; undulate line darker. Hindwing greyish-brown with white fringes. Massachusetts. 
G. pruena Dyar is similar to viridipallens Grt. (28 d), less green, more steel-bluish grey, the double pruena. 
transverse lines rather inconspicuous, between the two reniform maculae a black shadow; base of costal margin 
whitish, the undulate line shows darker spots. Hindwing greyish brown. Expanse of wings: 40 mm. Texas. 
G. puella Sm. (28 d) is a larger whitish-grey species with a black basal ray and blackish irroration, pue'lla. 
the base of the costal margin white, double transverse lines being almost straight, little dentate; the light 
maculae show a slight yellowish or reddish tint, the ring-macula reaching far downward, the reniform macula 
proximally produced on the median, between both a faded median shadow; instead of the undulate line there 
are small dark sagittae. Hindwing yellowish-brownish-grey. California. 
G. querquera Grt. (28 e). Forewing greyish-green with a black basal ray, double transverse lines and querqvera. 
an intense black median shadow; the maculae are laterally surrounded by black, the renifoim macida is centred 
brown; the undulate line consists of small black sagittae. Hindwing brownish-grey. New York. Missouri. 
G. unimoda Lintn. (28 d) has violettish-grey forewings irrorated with a brownish grey, with rather unimoda, 
indistinct transverse lines, the anterior line double, filled up with grey, the posterior line single, distally bordered 
with grey, crenulate; ring-macula whitish, above open, below distally with a bent streak, reniform macula in 
a grey ring; before the whitish undulate line there are small dark sagittae. Hindwing light brown. Canada; 
Northern and Eastern States (New York). 
G. laticinerea Grt. (28 cl). Forewing dark greyish-brown, strewn with white, with a black basal ray talicinerea. 
above bordered with white, with indistinctly double transverse lines filled up with greyish-white, and grey- 
ringed maculae, the ring-macula elliptical, connected with a similar spot below the cell, the reniform macula 
proximally produced, before the grey undulate line with small dark sagittae. Hindwing reddish-brown. Canada : 
North-Eastern States. 
G. Winnipeg Sm. is very similar to the two preceding species, but the ground-colour is decidedly dark Winnipeg. 
bluish-grey without the greenish tint of laticinerea. Expanse of wings: 46 mm. Atlantic States. 
G. antennata Wkr. (= cinerea Riley) (28 e) is somewhat like laticinerea (28 cl), smaller on an average, antennata. 
more violettish-grey, at the base of the costal margin more whitish-grey, the reniform macula pupilled reddish, 
behind it the subterminal area is somewhat lighter. Hindwing light brown. Canada and North-Eastern States. 
-—- The larva is green with narrow white dorsal lines and a broad white lateral stripe. 
G. cinerosa Grt. (= grotei Riley) (28 d) is also like laticinerea, but it has broader wings, a purer grey cinerosa. 
colorrr, coarsely strewn with black, the other marking cprite similar. Hindwing yellowish-brown. Canada and 
North-Eastern States. -—- Larva green with equally broad white dorsal and lateral stripes; it lives on maple 
and other deciduous trees. 
G. georgii Grt. (28 e) is a most variable insect. Forewing bluish-grey, irrorated with greyish-brown, georgii. 
with a black basal ray and strongly dentate transverse lines and maculae of the same shape as in the preceding, 
the ring-macula connected with a spot below it, the reniform macula proximally produced, before the black 
veins of the marginal area minute black sagittae of the undulate line. Hindwing reddish-brown. Canada, 
Northern and Eastern States. — The form emarginata Srn. (28 f) has very indistinct spots of the undulate line, emarginata. 
Colorado. — holocinerea Sm. (28 e) is somewhat darker brownish-grey with a distinct median shadow between holocinerea. 
the maculae. Canada to California. -— ancilla Sm. (28 f) entirely resembles the preceding form, but it is lighter ancilla. 
bluish-grey, at the base of the costa and in the subterminal area still somewhat lighter. From Canada. -— vertina vertina. 
Sm. (28 e) is somewhat more contrasting, more variegated, owing to the reniform macula being pupilled reddish- 
brown, the median shadow continued to the hind-margin (whilst in the preceding it is only confined to the cell), 
the posterior transverse line quite indistinct. Canada, Oregon. -— The form fletcheri Sm. (28 g) is distinguished fleicheri. 
by its small indistinct ring-macula without the usual spot below it. From Ottawa. -— oregonensis Harv. (28 f) oregonensis. 
has a much lighter whitish-grey ground-colour with a slight bluish tint, being the lightest at the base of the 
costa and in the subterminal area, the reniform macula being centred red-brown. Hinclwing lighter brownish. 
Oregon, Colorado, California. — The green larva with narrow interrupted white dorsal, subdorsal and lateral 
stripes lives on oaks. 
G. fagina Morr. (28 g). Forewing light violettish-grey, strewn with brownish, in the costal area whitish fagino. 
with finely black-striped veins, without a basal ray, with strongly dentate, submedianly connected transverse 
lines, with almost extinct maculae; failing them with short black streaks; instead of the undulate line small 
black sagittary spots. Hindwing yellowish-brown, veins and marginal area darker. North-Eastern States 
(Maine, Massachusetts, New York).
