C. pettiti Grt. (29 f) is also somewhat similar, invariably smaller, of a pale yellow ground-colour, densely pettiti. 
irrorated with fiery red, with blackish-brown veins; the reniform macula is below filled up with blackish, the 
median line is broader, more faded, behind the distal transverse line there are short dark vein-streaks. Canada; 
New York; Iowa. 
C. ceromatiea Grt. (29 f) has deep crimson forewings irrorated with a silvery grey, with darker red ceromuiica. 
transverse lines and small dark vein-streaks behind the distal line; the maculae are somewhat surrounded with 
whitish, the reniform macula is below pupilled dark; behind the whitish undulate line there are likewise dark 
vein-streaks. Hindwing ochreous-red. Canada; United States as far as New York, New Jersey. 
59. Genus: AaBastthes Hbn. 
This genus having been formerly denoted as Orihosia 0., and recently as Parastichtis Hbn., chiefly 
only differs from Conistra in the more cylindrical, scarcely flattened abdomen. Cf. also Vol. Ill, p. 150 and 
Vol. XI, p. 111. 
A. purpurea Grt. (29 g). Forewing purple grey, irrorated with red-brown, with double, feebly crenulate purpurea. 
transverse stripes, the maculae surrounded by brown, the reniform macula below pupilled blackish, with a 
faded median line and a grey, proximally dark-shaded undulate line. Hindwing greyish-brown. •— The form 
fortlica Sm. is based upon a very small specimen, of a more pinkish-brownish ground-colour, the latter being fornica. 
at any rate most variable in purpurea. —- crispa Harv. has a pale chestnut-red, postmedianly darker ground- crispa. 
colour, the hindwing is also chestnut-brown, in the marginal area lighter with a faded subterminal band and 
dark central luna. — antapica Sm. (29 h) is ferruginous reddish-grey. All the forms occur from Canada to antapiea. 
California. 
A. bicolorago Gn. (= spurcata Wkr.) (29 g) is, like purpurea , a very variable species; the type is reddish- bicolorago. 
yellow, in the marginal half irrorated with blackish-brown, with rather indistinct crenulate transverse lines 
and vein-dots behind the distal maculae which are surrounded with brownish, the reniform macula being below 
filled up with blackish; the median line separates the lighter basal half from the dark marginal part; behind 
the ochreous undulate line the marginal area turns lighter again. Canada and Eastern United States, to the 
west as far as the Mississippi. — The form ferrugineoides Gn. is not irrorated darker in the marginal half and ferrugincoi- 
shows distincter, more red-brown markings. — verberata Sm. (29 h) is a more yellowish-grey form with darker dcs. 
veins, in the postmedian area but very scantily irrorated with a darker brown. Canada to Colorado. 
A. acta Sm. is likewise similar, with longer and more pointed forewings, the colour varying from acta. 
light reddish-grey with a yellowish tint to ferruginous reddish-brown, with markings of the same colour though 
somewhat deeper, therefore not contrasting; transverse lines double, filled up with a somewhat lighter colour, 
with a very prominent median shadow; the light undulate line is proximally shaded with ferruginous; the maculae 
are surrounded with red-brown, the reniform macula is below pupilled leaden-grey. Hindwing light yellowish. 
Expanse of wings: 32 to 34 mm. Canada; Washington; Oregon. 
A. straminea Sm. looks like the uni-coloured forms of bicolorago . but it is smaller and with much more straminca. 
faded markings; forewing dull straw-coloured with brownish single transverse lines, in the post-median area 
somewhat darkened. Hindwing darker smoke-coloured grey. Expanse of wings: 28 mm. Colorado. 
A. decipiens Grt. (29 g) is a larger, bright yellow species, irrorated with red-brown, with very faint decipicns. 
darker markings, the reniform macula as usually below pupilled blackish, in the centre very much strangulated; 
the yellow undulate line is proximally shaded with reddish-brown. Hindwing of a subdued light yellow colour. 
United States (Indiana). 
A. ralla Grt. & R. (29 h) is smaller than the preceding, more brownish, with thicker though faded ralla. 
double red-brown transverse lines and 2 dark dots in the cell before the antemedian line; the ring-macula is 
obliquely elliptical, above open, the reniform macula centred with brownish; instead of the undulate line a row 
of dark dots, behind which the marginal area is irrorated with reddish-brown, except the apex. Hindwing 
yellowish-white. Eastern and Central States. 
A. puta Grt. <£■ R. (= eurora Grt. <£ R.) (29 h) is irrorated with a fiery reddish brown on its grey puta. 
ground, marked like the preceding with double transverse lines, an intense median shadow and brown-encircled 
maculae, a quadrangular ring-macula, above and below open; marginal area darkened, parted by the lighter 
undulate line. Hindwing light brownish-grey. Canada; Eastern States. — dusca Sm. (29 h) is still smaller dusca. 
and darker, with a more faded marking and shorter broader forewings. From Canada. 
A. inops Grt. (- insipida Streclc.) (29 h). Forewing yellow, irrorated with reddish-brown and strewn inops. 
with dark brown with faded brown transverse lines and vein-streaks behind the distal line; ring-macula small, 
round, the reniform macula below pupilled with a very intense blackish-brown; undulate line indistinctly 
lighter, proximally bordered with dark brown. Hindwing whitish, feebly brownish. United States (Maine). 
A. aggressa Sm. (29 i) differs from its allies by its very light yellowish-grey ground-colour, which aggressa. 
is irrorated with bluish-grey in the basal and marginal areas, with blackish double transverse lines and a distinct
