22 ACRONICTA. By Dr. M. Dratidt. 
veins. United States, to the south as far as Texas. — Larva light brown, watered with blackish, with broad 
black subdorsal lines above bordered with whitish; the tubercles show one single hair each. It lives on oaks 
A. ovata Grt. (3 d) is smaller and very much lighter grey, less brownish; the antemedian is in the 
centre broadly darkened with a blackish brown; by the reddish-brown reniform macula the species is rather 
easily recognizable; hindwing light reddish-brown, towards the margin darkened. From New York to Texas, 
to the west as far as the Rocky Mountains, May till July. — The adult larva is brown with yellow tubercles 
on which there are single hairs, and with large yellow, later on orange-red spots. It lives on oaks, beeches 
and walnut-trees. 
A. haesitata Grt. (3d) is much larger than ovata, darker bluish-grey with much darker veins; the 
antemedian line is similarly darkened, the reniform macula not filled up with reddish. Hindwing dark brown. 
From Canada to Texas and Arizona. -— Larva similar to that of the preceding, but without dorsal spots. 
A. pruni Harr. (= srnithi Btlr.) (3 d as hasta) is a larger light species with entirely the same markings 
as in theodora, but the black streak in the cliscal area above the submedian fold is absent , and the ground-colour 
is more brownish. Northern California. 
A. marmorata Smith (3 f). The figure reproduces the species just as badly as is the case in the prece¬ 
ding. The ground-colour is a faintly yellowish white in contrast with the black markings by which the species 
is well discernible from all the others known; the ring-macula is prominently white with a black pupil. Hindwing 
white with dark veins and a dark-brown marginal line. From California and Montana. 
A. fragilis Gn. (= spectans Wkr.) (3 e) agrees with marmorata in the whitish ground-colour and 
the sharply contrasting markings; in the inner-marginal half and towards the distal margin there is more intense 
blackish-brown strewing Recognizable by its smaller size and the absence of the black sagitta above the proxi¬ 
mal angle. Canada to New Jersey, to the west as far as the Mississippi. — Larva green with yellowish-white, 
interrupted subdorsal lines and a more or less complete brown dorsal line; single black hairs. On birches, ash- 
trees and apple-trees. 
A. minella Dyar (3 f) is darker and larger than fragilis, more brownish-grey intermixed with single 
ochreous scales, similarly marked, the anterior transverse line very much dentate, without the dark shading 
behind the postmedian line on the discal and submedian folds; the basal sagitta only extends to the anterior 
transverse line. Colorado. 
A. clarescens Gn. (3 e) has greyish-white forewings strewn with blackish-brownish; especially dark 
is the basal area except the space between the basal and proximal transverse lines, the two anterior transverse 
lines are very much less dentate than in minella. Hindwing darker brown than in minella. ■ — f. centriferru- 
ginea Strd. are specimens with a reniform macula filled up with rusty brownish. -—- From Canada to New York. 
— Larva green or reddish with single dark hairs and a purple brown dorsal stripe expanding on the segments 
7 to 10 and being on the thoracal rings laterally bordered with white. It lives on apple, cherry trees etc. 
A. tristis Sm. The ground-colour of the forewings is a uniform dark ashy grey with exactly the same 
marking as in the following inclara, but without contrasts, slightly relieved against the ground-colour, the 
light ring of the round ring-macula being the only greater contrast. Hindwing diaphanous white, dusted with 
blackish, in the $ darker. Expanse of wings: 35 to 37 mm. Described from Canada. 
A. inclara Sm. (3 e) by more intense black strewing, particularly in the basal and postmedian areas 
appears darker than clarescens which it resembles otherwise; particularly very much shaded are the discal and 
submedian folds behind the distal transverse line. — Larva similar to that of ovata, with or also without light 
dorsal spots. From Canada to Texas, to the west as far as South Dakotah and to the foot of the Rocky Moun¬ 
tains, in June and July. 
A. liturata Sm. (3d). Greyish-white, in some places tinged brownish and strewn with black; the 
black basal ray extends beyond the anterior transverse line; the markings are rather blurred, not contrasting; 
ring-macula purely white with brown pupil. Hindwing white with darker veins and darkened margin. Oregon, 
Colorado. 
A. brumosa Gn. (3 e) is one of the darkest species, very intensely strewn with brown and black, especially 
in the proximal third of the base and behind the distal transverse line towards the apex. Hindwing in the $ 
white, in the ^ brownish, the veins darker. Florida, Texas, Colorado. — f. persuasa Harv. has lighter hind- 
wings and is perhaps a distinct species. 
A. velia Schs. (3 e, 5 c) is very much like brumosa, lighter, particularly in the basal area; the basal 
ray does not extend beyond the anterior transverse line, and the anal sagittiform ray seems to extend very 
obliquely to the proximal angle by being very much shaded dark proximally above, distally more towards 
the proximal margin. Hindwing somewhat darker, the veins still more prominent; especially in the $ an undulate 
postdiscal line is distinct. Mexico to Guatemala. Figure 3 e is of a too bright blue and brown colouring, figure 
5 c, however, is correctly coloured.
