quite different, dark reddish-brown with black median spots, behind them a thick red-brown postmedian line 
being introangular on the submedian fold in both wings; before the darker red-brown margin there is a light 
indistinct undulate line bordered with dark proximally. From the Volcano of Chiriqui, Panama. 
A. crenulata Schs. (134 c) is likewise very similar to arcaei, but the hindwings more notched and with 
longer tails, as in the following batesii. Ground-colour dull greyish-brown, lighter whitish towards the costal 
margin in the median area; postmedian line scarcely darker than the ground; at the cross-vein a light spot 
bordered with dark; subterminal line undulated with small white vein-spots and a larger triangular spot above 
the interior angle. Ecuador. 
A. bafesii Fldr. is very similar to the $ of arcaei, with a deeper chestnut-red postmedian band, behind 
which there are white vein-spots and the subterminal line composed of double light blue arcuate lines. Fore wing 
and hindwing more intensely notched, the tail bicuspid, above it between 2 notches a deep indenture between 
6 and 7. Guiana. 
A. ponderosa Rothsch. (127 a) likewise approaches arcaei and is the largest species known, with a light 
yellowish-brown colouring, a very distinct submedian oblique line to the base of the inner margin, a conspicuous 
quadrangular Isabel-coloured spot between veins 4 and 5 behind the subterminal line which is only indistinctly 
double. Eastern Peru (Chuchuras). guayanensis Rothsch., from British Guiana, exhibits finer lines in the 
basal half of the forewing, a distinctly double subterminal line, the postmedian band being situate before it is 
broader than the marginal area. 
A. championi Drc. initiates another group with a more produced apex of the forewing, with a deep 
indenture at the distal margin below it. Eorewing lighter or darker reddish-brown, coarsely strewn with black; 
antemedian line double, interior line straight, exterior line almost rectangularly broken on the submedian fold, 
both united at the inner margin; the black discal spot oblong bean-shaped, rusty yellow in the middle; the 
darker brown postmedian band is strongly curved, outside bordered by a black undulate line; below the apex 
a dark marginal spot enclosing 3 still darker sagittal streaks. Hindwing with a short tail on vein 5. Central 
America, especially in Honduras and Panama. columbiana Rothsch. (126 c) is of a more violettish-black 
ground-colour, less strewn, the distal third beneath more grey. West and East Colombia. 
A. undilinea Schs. is allied with championi, light grey strewn with brownish; the incurved antemedian 
line extends to the centre of the inner margin, with a straight light brown nebulous stripe behind it; a long 
curved yellowish-brown streak at the cell-end, finely bordered with brown, postmedian band light greyish- 
brown, otherwise as in championi ; the subterminal line shows white vein-dots in both wings. Expanse of 
wings: 120 mm. Costa Rica. 
A. richardsoni Drc. (126 b) is smaller than the preceding species, the ground of the wings very light, 
brownish white, strewn with coarse blackish-brown spots, the interior antemedian line not straight, but distally 
notched on the median, the shadow behind it more distinct and thicker only at the inner-marginal half; the 
brown postmedian band is undulately dentate on both sides and traversed by lighter veins; marginal area very 
light, the subapical dark spot narrow; hindwing the same, but darker. Mexico (Guerrero). — mestiza /. n. 
(126 b) which may be a distinct species is much larger and more robust, darker, much less strewn, the interior 
antemedian line quite straight, the discal spot very broadly margined with black, with a distal appendage; 
postmedian band very broad and dark, still more excurved in both wings; subapical spot much broader, the 
extreme marginal half contrasting very dark with the inner half. Mexico (Zacualpan) several couples; type 
in the Coll. Draudt. The shape of the freshly emerged larva is like that of an Adelocepliala, the thorns on the 
2nd ring bicuspid at the ends, on the third of more than half the length of the body; the food-plant being- 
unknown, the larva could not be bred. 
A. romulus M. & W. (126 c) has still longer wings with very strongly extended apices. Ground-colour 
light greyish brown, finely strewn darker. Scheme of markings similar to that of championi, antemedian line 
only single, postmedian band very convex, lighter towards the costal margin, subapical spot very broad, deep 
red-urown. Hindwing with a very large discal spot and a very dark blackish-brown postmedian band and a 
rounded margin. Brazil. 
4. Genus: Titsiea Hbn. 
This genus based upon but one extremely rare species connects the armida- group of the preceding genus 
with Dysdaemonia. Structurally scarcely different, vein 5 of forewing arises from the centre of the cross-vein. 
Hind wing with a short tail. 
T. orsinome Hbn. (= latifascia Wkr.) (127 c). Eorewing light cinnamon brown with a dark fine 
antemedian line (distally shaded dark), discal streak and postmedian band, the latter may be of the ground¬ 
colour or darker. Hindwing with a slaty blue basal spot and postmedian band which is likewise bordered with 
slaty blue distally especially towards the costal margin. By the kindness of the Berlin Museum we were enabled 
to figure a fine couple.
