B. cancellata Warr. (175 f). The shape of the wings is not described by the author; judging from a 
specimen kindly placed at our disposal by Dr. Jordan, it resembles nervicula, but the denticulation is stronger 
on both wings. Wings brownish ochreous. Forewing with a blackish brown stripe below the costal margin 
proceeding from the base, broader outside, extending into the apex. Dark streaks at the costal margin, larger 
spots before the apex. The wing is traversed by 9 parallel vertical brown lines at equal distances, only the seventh 
line being somewhat more bent. Besides fine brown reticular lines. A white streak at the margin above vein 7. 
Hindwing with 5 parallel lines in the basal half and a very much ramified one from V 2 costal margin. 1 
50 mm. Peru. 
In the following species the apex is very pointed in both wings, 
the distal margin not or hardly notched. The anal angle of the fore- 
w i n g is angled, but not projecting .Hindwing without an angle at 
vein 8, faint traces o f i t only in p h y 11 u l a. 
B. phyllula Gn. (174 e $, f $). Wings somewhat more oblong and somewhat lighter than in nervicula. 
The fine and stronger lines are just as irregular. A straight median line on both wings may be worth mentioning 
at most. This species also shows the conspicuous white spot on the hindwing, which Herrich-Schaffer has 
omitted on his figure 403. The resemblance of phyllula and nervicula is considerable, yet they are probably 
different species. A tiny specimen with an expanse of 38 mm is before me from the Senckenberg Museum. 
55—60 mm. Brazil. 
B. patercula. Pagst. (174 g). Ground-colour pale yellowish, somewhat diaphanous, the marking red- 
brown. Costal margin of forewing red-brown as far as the apex, a subapical band terminates at the margin 
at vein 4. The median band from 3 / 5 costal margin to the middle of the inner margin, where it widens and 
encloses light dots. A large irregular spot in the middle of the marginal area above vein 2, with a side-branch 
extending to the anal angle. Hindwing with an equably broad median band enclosing a white dot at the cross¬ 
vein. A large square spot at the costal margin near the apex, a just as large anvil-shaped spot between veins 
2 and 4. Besides both wings are densely covered with red-brown reticular lines. The description refers to the 
type. All the other specimens which I saw are less intensely marked, so also the specimen from the Sencken¬ 
berg Museum, which we figure. In most of the specimens the median bands are only median lines; the same 
is the case with the subapical line. The last spot on the hindwing is almost invariably absent. A tiny specimen 
of 30 mm is before me from the Senckenberg Museum. 45 — 55 mm. Brazil. — fratercula Pagst. (174 f), according 
to the description, might be a very feebly marked patercula. We figure such a specimen from Blumenau in 
the Senckenberg Museum. The habitat stated to be California is improbable. <$ 42 mm. 
B„ arachnidia Warr. (174 g). Pale greyish yellow, with dense dark reticular lines, the lines and shadows 
red-brown. Forewing darker at the base, bordered by an irregular bent line. The median line is just as irregular. 
The exterior line from % costal margin to the middle of the inner margin, oblique, thick, forked at the costal 
margin, with a red-brown shadow behind it, which is narrow in front and reaches the margin at vein 2. A 
black streak below the costal margin in the last quarter to the apex, from its beginning a red-brown stripe 
extends to the margin at vein 4 Hind wing with a long light streak at the cross-vein, fadedly darker behind 
it. Darker also at the apex. $ 68 mm. Peru. 
B. sanguinea Warr. (175 a) shows the apex of the forewing very much produced, but the apex of the 
hindwing broadly cut off. As it is somewhat similar to the following frondicula Gn., we place it here, although 
Drac. peripheta is still more similar. Forewing brownish ochreous, diaphanous, the marking dark red-brown, 
hemochrome at the distal margin between veins 2 and 5. The inner margin dark red at the base as far as the 
submedian fold, where it meets a band proceeding from the median vein at the base of vein 2. A broader oblique 
band from the middle of the inner margin to the cell-end encloses a round pale spot. Both the bands are branched 
towards the costal margin, prolonged to the apex as a costal stripe, containing a few pale spots. A few oblique 
lines at the apex. A red-brown spot at the anal angle, pointed above, extending to vein 4. Before this spot 
two more as far as the median band and some above vein 5. The whole wing with reticular lines. Hindwing 
dark red. Paler near the base before the broad interior band, a larger light spot at the costal margin behind 
the 1 middle, a smaller one behind it, two at the anal angle. $ 60 mm. Cayenne, Amazons. 
B. frondicula Gn. (= matricula Gn.) (174 g). In both wings the apex does not project quite so much 
as in the preceding species. Ground-colour reddish yellow, somewhat diaphanous. Forewing red-brown at the 
base. As the beginning of the interior line there is a spot at the costal margin. Median band broad, divided 
at the costal margin, bent somewhat basad. A spot at the anal angle may be connected by irregular lines with 
the median band at vein 3. A triangular preapical spot the lower point of which is prolonged to a subapical 
line or row of spots. The costal margin is not throughout red-brown, by what it is well discernible from pater¬ 
cula. Hindwing with a basal and median band, the latter enclosing a white central dot. An irregular spot at 
the apex, interrupted and irregularly prolonged towards the anal angle. Besides the red-brown bands there 
are dense fine reticular lines on both wings, here and there blackish, the others red-brown. 55—70 mm. Brazil.
