in aroata, is distinctly interrupted behind the cell by a small light Inna; an almost quadrangular bone-white 
spot is above the antemedian black submedian wedge-spot. Hindwing purely white, feebly smoky at the inner 
margin. Antennae as in densissima. From Brazil (Sa. Catharina), type in the Senckenberg Museum, Frank¬ 
fort on the Main. 
B. densissima Dyar is vety similar, only half of the antennae are pectinated, the markings are finer densissima. 
and more irregular, the costal margin is not shaded dark, the light longitudinal stripe is absent above the olive 
brown shadow which extends into the apex. Hindwing brownish-grey, darker on the veins', inner margin and 
distal margin. Expanse of wings: 43 mm. Guiana. 
B. aposfatica Dyar has no pectinated but serrated and tuftedly ciliated antennae in the $. The light apostatica. 
yellowish longitudinal stripe from the base into the apex ist distinctly reddish-brown, not tinted olive as in 
aroata, the markings are more scanty, broader, the light apical blotch is absent altogether. Hindwing greyish- 
brown as in densissima; size somewhat larger. Expanse of wings: 45 mm. Guiana. 
B. empirica Dogn. (148 f). Eorewing yellowish greyish-brown, strewn with grey at the colstal margin, empirica. 
wdth brown veins especially above the centre; a brown longitudinal line traverse’s the wing from the base of 
the stibmedian vein, where it is crossed by white, to the distal margin between 5 and 6, forming long distal 
dents below it, du'sted whitish-grey anally. Hindwing white, brownish on the veins and margin. Mexico to 
San Salvador. 
B. schrottkyi Dogn. (148 f) has ash-grey forewings with a broad yellowish longitudinal band from the schrottkyi. 
base to the apex; white dusting above the anal angle, the light longitudinal stripe with a double brown and 
black border within this dusting; cellular branches partly marked brown; fringe speckled brown and yellow. 
Hindwing white, feebly brownish on the veins and in a narrow marginal line. Colombia, Bolivia, Paraguay. 
B. tucumartata Dogn. is similar to schrottkyi in the marking, but the wings are not ash-grey, but yellowdsh tucumanaia. 
greyish-brown as in empirica with darker fine veins; the forewing is traversed by a broad yellowish longitudinal 
band which begins at the base and terminates into the distal margin a little below the apex; above the anal 
angle there is likewise bluish-white dusting enclosing a black double spot; at the cell-end a dark-edged reni- 
form macula before which there is a small spot. Hindwing white. Argentina. 
57. Genus: Peroara Schs. 
Very near to the preceding genus, but without a tuft on the head, with longer haired palpi and with 
an entirely rounded distal margin of the forewing which shows the same neuration. Abdomen shorter and 
without an anal tuft. Only 3 species. 
Type of genus: P. sylvestris Schs. 
P. sylvestris Schs. (148 g). Thorax brown wdth white tegidae; abdomen bronze brown. Forewing grey, sylvestris. 
strewn with brown, darkest in the basal third, white at the cell-encl, traversed by a brown line; the posterior 
transverse line and a broad subterminal shadow are white, both bordered with brown inwards, a large dark 
subapical spot at the costal margin. Hindwing smoky brown. Guiana, Colombia, Bolivia. 
P. discovata Schs. is very similar to sylvestris, but separated by a different genital apparatus: the costal discovata. 
projections of the harpe are shorter, stouter and irregularly dentate, while in sylvestris they are altogether 
smaller and more gracile, long, slender and smooth. Forewing strewn more greyish-brown, less intermixed 
with white, traces of an anterior transverse line bordered with whitish inside; brown streaks behind the post¬ 
median line, irregularly spot-like below the centre, distalIv bordered by the white subterminal line. Hindwing 
whitish, veins and inner margin yellowish, margin broad greyish-brown. Expanse of wings: 37 mm. Guatemala. 
P. caterina Schs. (148 g) is similar to discovata, but larger and much darker; basal part of forewing eaierina. 
dark brown, intermixed with white scales; inner margin more whitish at the base, the rest white mixed with 
brown, with two dark median lines and a white, strongly notched postmedian and subterminal line; a large 
blackish-brown spot in the cell, a white triangular spot mixed with reddish-yellow is behind it; a dark costal- 
marginal spot before the sub terminal line, with black longitudinal streaks; fringe red-brown, crossed by 
yellowish on the ends of the veins. Hindwing light brown, darkened at the margin. Brazil (Blumenau). 
58. Genus: Oopha Wkr. 
The male antennae are shortly pectinated in the basal two thirds, serrated and tuftedly ciliated in 
the $; palpi oblique, with a long middle joint and a short terminal joint. Forewing broad with a straight costal 
margin and a sharp apex, slightly concave below it, the rest of the distal margin straight. Neuration as in 
Lirimiris. Only few species are known.
