0. truncala Wkr. (141 f) is the most easily discernible species; forewing above yellowish-grey with a 
slight olive shade and 4 lighter transverse lines, the first from the first third of the costal margin straight to 
the inner margin and like the second somewhat narrower and more indistinct line distally bordered with brown, 
the 3rd and 4th subterminally near together and between them with a darker filling; close behind the distal 
line between 4 and 5 a small dark brown spot, and above 5 a hyaline spot; fringe speckled somewhat darker. 
Hindwing darker brown with a light median line which is very distinct beneath. Rather common, from Brazil. 
Q„ irrorata Btlr. (141 f) is somewhat smaller, reddish-brown, with dark red-brown scales, and basally 
and in the proximal half of the inner margin strewn with large lilac-whitish scales, with 4 dark brown transverse 
lines, the first as in truncata inside bordered with lilac white, the second near behind it, somewhat wavy, and 
distally angled on 1; then follows a fine light cross-vein streak distally bordered with dark; postmedian line 
curved round the cell-apex, subterminal line angular between 5 and 6, with a hyaline spot behind it. Hindwing 
somewhat lighter and more reddish. Guiana; Amazons. 
0. amelda Dyar (141 f) is somewhat similar to irrorata by the dense lilac-grey strewing on the brown 
ground, but the transverse markings are represented here by quite obsolete darker brown bands being only 
noticeable by less light strewing, one being antemedian, one postmedian, a very feeble subterminal one, and 
the fourth close at the margin w'hich is hardly dentate here, the projection on 5 is also but little rounded. The 
hyaline spot is somewhat larger than in irrorata, sometimes there is below it another very small one. Hindwing 
red-brown, with a slightly darker subterminal line. Mexico (Zacualpan). 
0. cuyabata sp. n. (141 f) resembles the following bilinea, but it is smaller, darker, and much more 
variegated owing to the coarser brown strewing; the two antemedian lines are more undulate, especially the 
outer one which is inwardly angled on the submedian fold and outwardly on 1 ; at the cell-end a whitish transverse 
streak; postmedian line behind the cell obtuse-angularly rounded, it is the strongest of the lines, closely followed 
by the very fine feeble subterminal line, behind it another undulate-dentate submarginal line; the small hyaline 
spot on 6 is almost cpiite absent. Hindwing lighter reddish-brown with a median line which is angled on 6, 
and a feebler subterminal line. Type 1 $ from Cuyaba (Matto Grosso) in the Berlin Museum. 
0. bilinea Schs. (141 f) shows quite similarly arranged lines as irrorata, but the ground is here a brownish 
light grey, the lines are fine and dark, not edged lighter, 2 somewhat feebler antemedian lines, the 3rd is exactly 
in the middle and more distinct and darker than the others, almost straight; subterminal line almost undulate- 
dentate ; behind the small hyaline spot there is another line being dentate as in amelda and disappearing analwards, 
behind it the margin is somewhat darker grey. Hindwing light reddish-brown with 2 shadow-like darker 
transverse lines. Brazil. 
0. azteca Schs. (141 f) is somewhat larger, bluish ash-grey, strewn with brown, between the two 
antemedian and between the two postmedian lines of a brighter brown; the two anterior lines are slightly 
undulate; at the cross-vein a black dot amidst whitish scales; postmedian line almost rectangular on 6, behind 
the subterminal line especially analwards somewhat more intensely strewn with whitish; behind the yellowish 
hyaline spot an undulate-dentate short submarginal line disappearing analwards in a whitish brightening. 
Hindwing light red-brown, in the inner-marginal half and at the distal margin broadly darkened, with 2 rather 
distinct median and postmedian transverse lines. Mexico and Guatemala. 
0. avangareza Schs. (141 g) is extremely similar to azteca and probably only a form of it; somewhat 
smaller, lighter, the transverse lines nearer together, the ground between them less contrastingly brown, the 
black discal dot absent : the undulate-dentate submarginal line is more distinct and continued to the anal angle; 
apex of the wing somewhat sharper, like the marginal dents, too. Hindwing lighter brownish. Costa Rica. 
0. angelica Grt. (= hyalinopuncta Pack.) (141 g) is in the male somewhat more slender than the 
preceding species, the abdomen is longer. Fore wing light ashy grey with 2 nebulous light brownish slightly 
undulating antemedian and postmedian transverse bands; the anterior one has before it one dark, dot each 
on the median and submedian fold, the posterior one behind it a row of vein-dots, which are connected by more 
or less distinct brownish undulate lines; then follows another very feebly marked brownish subterminal band 
and subapically a quadrangular and below it a smaller triangular, distally finely brown-edged hyaline spot; 
fringes brown, at the ends whitish. Hindwing brownish-grey with a feebly darker median line and distally 
light-edged postmedian line. Atlantic States. —, indistincta Ii. Edw. is somewhat more brownish, more coarsely 
strewn and with quite obsolete transverse markings. Florida. seraphica Dyar differs in the less deeply dentate 
distal margin, smaller hyaline spots, the upper one of which sometimes disappears altogether, and the grey, 
not brownish, feeble transverse bands; hindwing also greyer and without any reddish tint. Texas. The larva 
of angelica is grey with a brown head; on the body fine black longitudinal lines assuming a V-like shape on the 
dorsum of the segments 5 10 and enclosing 2 small yellowish-green elliptical spots; the head is covered by 
the long whitish and brown, anteriorly projecting hair; between the long white hairs which are in places densely 
arranged like brushes there are single shorter stiff red bristles. The larva lives on ashes and lilacs.
