the black basal ray and the anal submedian ray are very sharply marked. Hindwing white, in the $ towards 
the margin brownish and with a dark postmedian band. Canada, Nebrasca, Cansas, also in California. 
A. strigulata Sm. (3 i). By the peculiarly bluish-grey colour of the forewing without distinct transverse 
markings and by the smaller size, this species is easily discernible; the veins are more or less distinctly striped 
white, between it towards the margin striped black, 3 subapical and 2 anal stripes being more prominent, the 
upper one being almost connected with a long, black basal ray. Hindwing purely white, in the $ towards the 
margin brownish. Colorado. 
A. thoracica Grt. (3 i) has a similar bluish ash-grey ground-colour, but with a yellowish admixture 
particularly towards the margin, especially easily recognizable by its ochreous centre; the transverse stripes 
are similarly extinct as in strigulata , but the veins not striped white, but dark, particularly in the marginal 
area; a long black basal ray, in the marginal area 2 subapical resp. anal sagittae; base of proximal margin and 
the pupil of the reniform macula reddish-yellow. Hindwing whitish, tinted brownish. From New York, New 
Jersey, Florida. 
A. laetifica Sm. (3 g). Forewing almost yellowish-white, strewn with a pale brown, with a long black 
basal ray, and 2 sagittae in the marginal area. Transverse lines distinct, the maculae connected by a black 
streak extending into the lower margining of the reniform macula. Hindwing whitish, tinted brownish. From 
New York, New Jersey, Florida. 
A. hasta Gn. is closely allied to the following furcifera (3 h), but it has a pure grey ground-colour, 
in some places dusted darker; all the markings are distinct, the slightly S-shaped postmedian band is distally 
bordered with dark. Hindwing white, in the $ darkened. Canada, United States. — f. telum Gn. differs but 
little from typical specimens. 
A. wanda Buckholz is similar to laetifica and hasta f. telum , but the forewings are as dark as in tritona 
with a contrasting light undulate line. Hindwing light greyish-brown, towards the margin darker. New Jersey. 
A. manitoba Sm. (3 i). Greyish-white, densely strewn with blackish, with a distinct black basal ray 
above edged with white and not crossing the anterior transverse line; the ring-macula, ends downward in a 
point and is connected with the reniform macula by a thick black streak. Marginal area with blackish veins 
and distinctly prominent sagittae on the discal and submedian fold. Hindwing white, with brown veins, in 
the $ brown. Canada, Colorado. 
A. furcifera Gn. (3 h) differs from manitoba by its brownish grey ground-colour with a reddish reflec¬ 
tion, the hindwings being somewhat darkened, the markings otherwise very similar, also like in hasta; the posterior 
dentate transverse line is white, only distally bordered with black. Widely distributed from Canada to Florida. 
•— The larva is black with light brown tubercles, with small reddish hair-rosettes and a broad red dorsal stripe 
which is narrowly edged with velvety black from the 3rd to 11th ring. It lives on cherries. 
A. rapidan Dycir (3 c) is extraordinarily similar to furcifera (3 h) at least according to the fresh specimen 
I received from Mexico (Teliuacan) and which is reproduced in the figure. Besides I got 2 smaller, very much 
flown, more yellowish brown specimens with the hindwings dusted with a yellowish-brown and a submedian 
darkening in the discal area between the transverse lines; though it is not mentioned in Dyar’s original descrip¬ 
tion, they are presumably nevertheless rapidan. It may be therefore, that also furcifera occurs in Mexico which 
might not be impossible owing to its occurring in Florida, rapidan is described from Mexico (Misantla, in May). 
A. lobeliae Gn. (= grotei Btlr.) (3 h ) is a well-known large species easily recognizable by the 3 very 
prominent sagittae; the comparatively light grey forewings contrast with the dark hindwings. Widely distri¬ 
buted from Canada to Florida and Texas. — Larva coloured from a slaty grey to black, with greenish white 
dorsal and subdorsal lines and indistinct lateral and sublateral spots; tubercles above black, laterally with 
longer white hair. According to Dyas with an interrupted red dorsal line. Food-plant: oak. 
A. tritona Hbn. (3 h). Forewing densely scaled, bluish or violettisli grey, dusted with brownish, with 
a very distinct basal ray and anal sagitta, the other markings little prominent. Hindwing brownish-grey, 
towards the margin darker. From Canada to Florida. — Larva vellowish-green with a purple brown dorsal 
stripe, interrupted on the 6th ring, parted on the 8th to 12th, enclosing an elliptic area of the ground-colour. 
Tubercles with single long hairs. It lives on species of Vaccinium and on Azalea viscosa. 
A. elizabeta Sm. (3 i as elizabetha) is browner than the most closely allied species with a black basal 
ray sending in the middle a branch downwards; maculae small, especially the reniform macula is a small, narrow 
luna. The white hindwings are dusted with brown. From New Jersey. 
A. falcula Grt. (3 g) is easily recognizable by the dark bluish-grey ground-colour with a distinct black 
basal streak and reddish dusting in the basal area and in the marginal area. Hindwing white, in the $ yellowish, 
darkened towards the apex. Canada, New York. Larva dark brown, watered with greenish, on the ventrum 
greenish-white, with a dark dorsal line, tubercles with 1 or 2 hairs; it lives on hazelnut.
