and narrow with a completely rounded interior angle, a very long narrow areole from the apex of which the 
veins 7 and 8 arise stalked, 10 arises above before its end. Hindwing as in the preceding species. 
Type of genus: A. combusta Herr -Schaff. 
A. combusta Herr.-Schdff. (147 e) has light reddish yellowish-brown forewings with narrow dark red- combusta. 
brown margins, a scarcely darker longitudinal stripe through the cell as far as the margin, interrupted on the 
cross-vein by two reddish-brown transverse streaks which are bordered with light; a narrower darker, more olive 
longitudinal stripe below the cell stops in the subterminal area before a small black spot, with traces of a deeply 
dentate postmedian line before the margin. Hindwing lighter than forewing, dark red-brown at the anal angle 
with light lines. Brazil. 
A. imitans Schs. is exactly like combusta, but easily discernible by the brown hindwing being only imitans. 
yellowish-white at the costal margin and in the upper half of the cell, and the forewing showing intermixed 
olive green colour before the fringe. Expanse of wings: 57 mm. Costa Rica. 
A. lignaris Schs. is also very similar to the two preceding species, but easily separable from them by the Ugnaris. 
dark greyish-brown shading behind the cell as far as the margin between the veins 4 and 6; moreover, the frons 
is dark brown, only the vertex light. Hindwing light as in combusta. Expanse of wings: $ 54, Q 73 mm. 
Costa Rica. 
A. postbrunnea Eothsch. likewise resembles combusta-, forewing reddish-yellow, with an olive tint, brown post- 
at the margins, with a brown longitudinal shadow below the median vein and a reddish-yellow reniform macula brunne 
at the cell-end, enclosing two darker lines; the darker postmedian line is indistinct, double and filled with a 
lighter colour; 2 fine pink lines in the brown margin, a broader reddish-yellow line before them. Hindwing 
sooty blackish-brown, reddish-yellow with an olive tint in the basal two thirds of the costal margin, the basal 
third and the inner-marginal area; two pink lines at the anal angle. Expanse of wings: 56 mm. French Guiana. 
52. Genus: liirimiris Wkr. 
Extremely similar to the preceding genus, only separated by the long double pectinations of the antennae, 
the apical quarters remaining plain. The apex of the long and narrow forewing is often somewhat truncate, 
the distal margin slightly concave above the anal angle. The mark of distinction hitherto assumed, i. e. the 
separate origin of veins 3 and 4 on the hindwing, has proved to be variable. 
Type of genus: L. lignitecta Wkr. 
L. lignitecta Wkr. (= argentifera Drc.) (147 d, e) has white forewings, the distal three quarters of the lignitecta. 
costal margin being deep blackish-brown; excepting the basal area, the larger inner-marginal half is scaled 
olive grey, a large clover-shaped reniform macula being open above, composed of erect scales, is at the cell-end, 
traces of a deeply notched dark posterior transverse line and of a white submarginal line are present. Hindwing 
white with a narrow brown margin. Widely distributed from Mexico to Brazil. — By the kindness of Mr. Arp 
there are large specimens before me from Brazil, which, in contrast with the Mexican specimens, have quite 
blackish-brown hindwings, — in the type they are white as in the J —, the forewing being tinged with pink, 
the reniform macula of a yellow tint, and the collar intensely ochreous, dark brown in the typical form; the 
form may be named: — arpi /. n. (144 e, f); it is probably a distinct species. arpi. 
L. auriflua sp. n. (147 f) is at once recognizable by the bright orange anal end. Forewing very narrow, auriflua. 
marked very much like the preceding species; forewing white, ^ith a narrow blackish-brown stripe from the 
basal third of the costal margin, interrupted in the distal third by 3 white small costal-marginal hooks, dusted 
with light brown in the inner-marginal half into which the large white reniform macula extends; all the linear 
markings are very indistinct, a short black longitudinal streak in the basal part below the cell and short black, 
very oblique postmedian streaks, especially towards the inner margin more distinctly bordered with white 
and double here. Hindwing distinctly triangular, diaphanous white, narrowly bordered with blackish-brown 
only at the costal margin and analwards, the inner margin clad with smoky brown hair. Several SA from Brazil 
(Rio) and Eastern Peru (Chuchuras). Type from Rio in the Berlin Museum. 
L. tnmcata Herr.-Schdff. (147 f) is the chief representative - of an extremely difficult group, since my truncata. 
examinations have yielded no fewer than 3 specimens in Mexico alone, which are scarcely distinguishable 
externally, but which can be distinctly separated by the genital organs. As the type of this species I consider 
the form which occurs most commonly and is most widely distributed in Mexico. The costal-marginal part of 
the forewing is light brownish ochreous, warming into white towards the blackish-brown inner-marginal part, 
with 2 or 3 small brown or blackish dots at the cell-end; the apical area is slightly brownish and encloses a few 
fine black wedges and small light costal-marginal hooks; a light line before the margin, then follows a black 
fine line, another black line is at the base of the brown fringe. Hindwing white in the disc, smoky on the veins 
and margin, with smoky grey hairs along the inner margin. The $ has broader wings, the hindwing is quite 
greyish-brown. The hindwing of this species is shortly triangular and rather deeply concave before the anal angle.
