RISAMA. By M. Gaede.

B. reticula Gn. (= mediovincta Warr.) (174f). Placed to Risama by Hampson, but probably better 
ranged here. Forewing as pointed at the apex as in frondicula , hindwing pointed at the apex, but not projecting. 
Ground-colour yellowish hyaline with a red-brown marking. Costal margin of forewing somewhat paler red- 
brown. The interior band vertical, ending at vein 1. The median band very broad at the costal margin, very 
narrow from vein 3, somewhat outward as far as vein 1, containing a round spot of the ground-colour above 
it and widened. A dark reticular line from the anal angle upward almost to vein 4. The red-brown colouring 
at the costal margin gets narrower towards the apex. Hindwing with dense reticular lines at the margin and 
the same from % inner margin to the cross-vein. 55—60 mm. Brazil. — mediovincta Warr. (175 e) differs 
very slightly in the reticulation, the margin of the hindwing is quite linear, as if it were cut off with scissors. 
It does not deserve a special denomination. 
B. purpureofasciata sp. n. (175 a) has more stretched wings. The distal margin of the forewing with 
the pointed apex and the angle at vein 3 resembles the following species, but the margin is very oblique below 
vein 3, and the hindwing is much more pointed at the apex. The marking is somewhat similar to selenioides. 
The body is dark pink. Forewing yellow, densely covered with reddish brown little strokes. The transverse 
bands dark violet. A short vertical band from the costal margin to the base of vein 2. A band from the middle 
of the inner margin to % costal margin, much broader from vein 3 and extended from the middle of the costal 
margin almost to the apex. From its exterior point a straight submarginal band extends to vein 2, where it 
is indistinct and broader. Hindwing with a double interior line. Median band extra-angular between veins 4 
and 5, broader above it, straight below it to behind the middle of the inner margin. Hindwing with fine dark 
streaks,- somewdiat reticular. Ground-colour beneath lighter, the marking distinct, J 45 mm. Type in the 
Senckenberg Museum (Frankfort on the Maine). 
The two following species exhibit a rounded apex on the hind- 
wing. The marking is somewhat variegated. 
B. selenioides Pagst. (175 a). Wings yellow in the distal halves. Forewing olive brown in the basal 
area. The median band very broad at the costal margin, occupying almost y 3 the length of the costal margin. 
Its distal margin uniformly bent from % costal margin to the middle of the inner margin, the interior edge 
outward as far as the base of vein 3, then inward parallel and close at the exterior edge; the band is darker 
in its lower part. The costal margin is spotted greyish white as far as the end of the median band. From its 
exterior angle a subapical band extends to vein 3 and a fine line to the anal angle. Hindwing with a broad 
olive brown median band, somewhat broader at the costal margin. A line from its angle to vein 3 at the margin, 
where the latter is somewhat excurved. 40 mm. 2 from the Clxanchamayo. 
B. excessiva sp. n. (175 a). Costal margin of forewing more undulated than in selenioides, somewhat 
more projecting at the middle of the distal margin, but uniformly bent at the distal margin of the hindwing. 
Body and base of forewing somewhat red-brown. Wings brownish ochreons, the marking red-brown. The 
median band of the forewing shaped like that of selenioides. A triangle close behind it at the costal margin 
as far as the apex from which, below at vein 6, two lines proceed, ending at vein 3 and at the anal angle. Be¬ 
sides numerous finer parallel lines. The median band is continued on the hindwing in the same width. Also 
here numerous parallel lines. The same beneath. $ 22 mm. Rio de Janeiro. Type in the Senckenberg Museum. 
20. Genus: liisama Wkr. 
Palpi horizontally porrect. Forewing very deformed in the typical species and the following one, widely 
excurved behind the base at the costal margin, inserted in the middle of the costal margin, the apex projecting 
pointedly, the distal margin cut out above the anal angle. In the other species the anal angle is not cut out, 
the apex projects much like a sickle. No veins stalked on the forewing. Veins 6 -f- 7 of the hindwing on a short 
stalk. Type: picta Wkr. 
R. picta Wkr. (= aurorula Gn.) (175 b). Forewing pink in the convexity at the base of the costal margin, picta. 
moreover in a triangle from the base of vein 2 along the latter and the distal margin almost to the apex, the 
rest glaringly light yellow. Dark brown circles, forming a band near the base, two of them replacing an interior 
line, a ring above the middle of the inner margin, small spots at % costal margin and at the excision of the 
anal angle. Hindwing light yellow at the base. Median band broad, brown, with yellow dots, enclosing a large 
round hyaline spot. The inner margin behind it broadly yellow, the distal margin narrowly brown at the anal 
end, the rest of the wing pink. 40—44 mm. Brazil. 
R. satellifera sp. n. (175 b). Costal margin of forewing less convex at the base, but the anal angle stdl satellifera. 
cut out. Ground-colour brownish pink. Forewing densely covered with rows of dark brown streaks, some¬ 
what darker at the anal angle. A dark brown short double streak extending obliquely outward from % costal 
margin is the only marking on the forewing. The striation on the hindwing is somewhat less distinct in the 
marginal area, somewhat darker only at the anal angle. Median band similar to that of picta , marked only 
like a shadow. The hyaline spot as in picta, close beside it towards the anal angle 3 small accessory spots. Beneath 
similar to picta, except the absence of the yellow colouring. The median band extends farther in front on the 
forewing, it is broad and distinct on the hindwing. 36—38 mm. Minas Geraes, type in the Senckenberg Museum, 
taken by Prof. Seitz in March 1930.
