projection at the middle, besides a parallel line before it. The exterior band is broader, especially at the costal 
margin. A fine transverse line at the apex. Hindwing with a broad median band behind the hyaline spots. 
24 mm. One specimen from Jalapa in Mexico. 
D. sica Drc. (173 a). This species and the following ones have no more a distinct exterior band on the 
forewing, but a spot at the costal margin, from which a line proceeds to the inner margin. Ground-colour 
orange. Two fine dark lines in the basal area. A brown postmedian spot at the costal margin, from the edges 
of which one dark line each proceeds meeting at the inner margin. A distinct apical transverse line terminates 
at vein 3. and a short line vertically above the anal angle. Hindwing with a faded dark median band, broader 
at the costal margin, from where a line extends to the anal angle. 26—28 mm. Described according to a series 
from Tabasco. My only specimen from Panama shows 2 separated hyaline spots on the hindwing, which are 
not mentioned nor figured by Dritce. 
4. The following species have no transverse line at the apex. 
D. traumatias Dyar. Leather brown, tinged with violet. Forewing with a light red spot behind the 
cell. Reticular lines fine, spotted. The exterior line is only marked by a dark triangle at the costal margin, 
without any other lines. Hindwing with a large hyaline spot, deeply indented, followed towards the inner 
margin by a yellow spot with red reticular lines. 23 mm. One specimen from Jalapa. 
D. remie Dyar. Reddish like speculifera, but the distal margins darker in both wings. The striation 
is coarse, the lines are thin, the exterior line proceeding from a triangular spot from 2 / 3 costal margin on the 
forewing. Hindwing with a straight fine median line, with 2 small white spots before it. Probably only a form 
of the following species. 23 mm. Panama. 
D. lusia Drc. (169 f). The description of the forewing agrees exactly with that of remie. Druce mentions 
also an apical line in his description, but according to the figure this is evidently no oblique line, but one of 
the numerous parallel lines, which is somewhat more prominent. Hindwing without the dark median line and 
the hyaline spots. 27 mm. Tabasco. 
D. spissicornis Warr. (173 b). Yellowish red. Forewing tinged with olive brown at the costal and 
inner margins, the reticular lines and transverse lines faded, dark brown. The basal line and interior line 
narrow, the exterior band broader, projecting outward above the middle, darker in the submedian fold. 4 pale 
spots at the costal margin, one before the middle, the others behind it. Hindwing only with reticular lines, 
the inner margin somewhat yellower, without any olive brown colour. The cellular spot is divided, forming 
two fine dots at the two angles of the cross-vein. 28—30 mm. 3 dd known from Rio de Janeiro. 
D. ingenicula Dyar. As this species as well as spissicornis differ from nearly all the others in their 
considerable size, it might be only a form of spissicornis. Ground-colour copper red with coarse and fine reti¬ 
cular lines. Costal margin and apex of fore wing darker. The exterior band is broader at the costal margin, 
with a projection on both sides. Hindwing with a similar band which is absent in spissicornis, but there is 
only a single hyaline spot present. 32 mm. Venezuela. 
D. callista Dyar. Body and forewing light ochreous, yellow at the anal angle, the apex broadly violet 
as far as the middle of the costal margin and to the angle at the distal margin, enclosing 3 pale spots at the 
costal margin. Before this apical spot a band from the costal margin to the submedian fold, below it two 
oblique darker bands to the inner margin. Hindwing brownish ochreous at the base, yellow at the margin, 
the median band violet, broad, forked at the inner margin. The hyaline spot is large, square, indented, yel¬ 
lowish hyaline. 27 mm. Described according to 1 specimen from Venezuela. 
4. Genus: Merdonia Wkr. 
The genus has already been dealt with in Vol. II, p. 372, since one species, the typical one, occurs in 
India and penetrates into the palaearctic regions. Besides it the genus contains but 4 more species, all from 
America. 
H. miranda Warr. (173 c). Pale brownish ochreous, with some reddish brown here and there. Black 
double streaks with traces of a green filling at the base of the forewing and also a little at the beginning of 
the costal margin. Less distinct streaks above the inner margin as far as the base of vein 2. From veins 6 to I 
an ‘oblique dark greenish brown band, edged with white on both sides. A paler brown submarginal stripe, 
slightly blended below the apex, widened at the anal angle. Hindwing similar. The basal spots numerous, 
the greenish brown median band in front very broad. The submarginal band is ramified at the apex. The 
size is most variable in this magnificent species. 35—55 mm. Described according to 1 couple from Fonte Boa 
(Upper Amazons); we figure a couple (<$ from Tring from Jaragua, 9 from the Senckenberg Museum from 
Joinville in 8a. Catharina). — isoldae Kohler is said to have a grey oblique stripe, lighter than the submarginal 
stripe. 50 mm. From Argentina. The slight difference may be merely individual. 
H. thetis Drc. (173 b). The contours of the wings on the original figure and the marking on the hindwing agree 
better with tristriata Pag. and quinquelineata Warr. which we have dealt with in the genus Rhodoneura. thetis is 
very pale and scantily marked. Body and forewing yellowish white. Pale brown double streaks at the base and
