L. euribya Drc. (147 g) is very similar, but much smaller, with a straight costal margin; forewing light euribya. 
yellowish reddish-brown, lightest at the apex and distal margin, with a dark brown longitudinal line through 
the wing from the base into the apex. Hindwing blackish-grey, darkest at the inner margin and apex. South- 
Eastern Peru. 
L. fascis Schs. (147 h) introduces another group of species which look very much like Arhacia combust a fascia. 
from which, however, they are at once discernible by the antennae being strongly pectinated also in the $. 
Forewing light brownish-yellow, narrowly red-brown at the margins, with a lighter central line before the 
large reddish-brown reniform macula, the cell shaded darker olive and surrounded by a lighter border; traces 
of darker double transverse lines. Hindwing greyish-brown, narrowly yellowish at the margin, with double 
red-brown lines and a dark anal spot parted by white. Mexico to Brazil. 
L. meridionalis Schs. (147 h) is considerably larger and darker than fascis, otherwise very similar; mericlio- 
forewing olive brown, darker at the costal margin, dusted with red-brown in and below the cell. Hindwing 
darker blackish-grey with a double black marginal line. British Guiana. 
L. lenioulti Rothsch. (148 a) is smaller and much darker than meridionalis. Head and thorax dark lemoulti. 
brown like the foi'ewing, basal part somewhat lighter with very high pointed arches of the antemedian line, 
otherwise marked very much like meridionalis , the postmedian line more distinctly prominent than dark wedges 
which are distally bordered with light. Hindwing deep blackish-brown with traces of a lighter postmedian 
band, and a rusty brown anal spot bordered with black inside and outside. Guiana; the Berlin Museum con¬ 
tains also a specimen from Para. 
L. mirabilis Rothsch. (148 a). This peculiar animal is not to be mistaken for any other species, the mirabilis. 
long narrow curved forewing is concave in the lower two thirds of the distal margin; the colour is whitish reddish- 
yellow, slightly dusted brown in the distal half, with a large olive brown spot at the cell-end, enclosing a light 
reniform macula from which a light stripe extends below the apex; the distal half of the costal margin is sooty 
blackish-brown, with small chocolate-brown apical spots; a feeble dentate double postmedian line is visible. 
Hindwing white, brownish at the margin of the $. Peru, Venezuela. 
53. Genus: Arpema Schs. 
The genus contains only two large very similar species with broader wings than the preceding genus. 
Palpi and antennae as in the latter; vein 5 of forewing arises directly above the centre of the cross-vein, 6 
before the centre of the areole from the end of which all the subcostal branches except the uppermost arise; 
the cellular branches of the hindwing arise without stalks and not separated by twos from the angles of the 
cell, the costal vein branches off from the subcostal vein before its centre. 
Type of genus: A. megalopia Schs. 
A. megalopia Schs. (= bucephaloides Rothsch.) (148 a). Forewing leaden grey in the small basal area, megalopia. 
bordered with white, covered behind it with very coarse white scales which are brown at the ends, greyer in 
the narrow median area; behind it follows a slightly distally concave white postmeclian line which is edged 
with reddish cinnamon outside and borders on the darker lilac brown sub terminal area; marginal area light violet- 
brown, traversed by two undulated lighter lines. Hindwing red-brown. Brazil. 
A. phaleroides Rothsch. (148 a) is very similar to megalopia and differs in the triangular violettish-brown phaleroidcs. 
basal area which is distally boidered by a white oblique line; the dark subterminal area is lighter and narrower 
and is not bordered inside by such a distinct white line. Hindwing somewhat lighter. West Colombia; Peru. 
54. Genus: Centra Schrk. 
Separated from the preceding genera by a very much shorter areole of the forewing, vein 6 arising 
almost from the end of the areole, 7 and 8 arising stalked from it. Vein 6 of hindwing stalked with 7. Antennae 
pectinated to the ends, palpi short. As to further particulars and the biology of this genus occurring also in 
the palaearctic region we refer to Vol. IIT, p. 285. 
Type of Genus: C. furcula Schrk. from Europe. 
C. scitiscripta Wkr. (= platea Schs.) (148 b) is the well-known American species with white forewings, scitiscripta. 
two antemedian and three postmedian black dentate transverse lines, the posterior one fourfold at the costal 
and inner margins, with a ring-shaped cellular macula in the centre. Hindwing white with black marginal dots. 
— f. multisctipta Riley is a somewhat darkened form, the transverse lines being filled with black scales, with multi- 
blackened hindwings. Larva of the usual pussmoth shape, light green, head and neck-spot on the thoracal scripta. 
segments blackish-brown, the saddle-spot on the dorsum lighter brownish, dusted almost entirely bluish-white
