species of this group. Two of them exhibit a large hyaline spot on the hindwing, whereas in two others it is 
divided by a dark vein. A fifth lacks the submarginal line on the hindwing, the hyaline spot being divided. 
The latter specimen, however, cannot be derufata , since the ground-colour is as reddish as in speculifera. 
D. pyrsocoma Dyar differs from specxdifera (173 b) in its broader bands. The wings are narrower, hued pyrsocoma. 
with fiery red. By this different colour it is distinguished from olivescens Warr. The discal spot on the hind¬ 
wing is large in pyrsocoma and olivescens. 1 specimen from Costa Rica served as the type for the description. 
D. confusata Warr. (173 b) has a smaller discal spot on the hindwing. The bands and lines are likewise confusata. 
broad. The reddish or brownish ground-colour is less extensive than in speculifera , darker. The broad main 
band shows at its interior edge in the centre of the wing a projection towards the base almost as far as the 
interior band. A specimen kindly put at my disposal by Dr. Jordan shows merely a small angle there, but 
a dark line extends from there steeply to the inner margin. The same is the case in olivescens (173 b). The 
light places on the hinclwing are still more reduced, because the bands are broader. The hyaline spot is small, 
8-shaped. 28—30 mm. Ecuador. — The type shows a deep copper red ground-colour, but it may also be

light places at all. The hyaline spot is large.

D. derufata W arr. (173b) differs from speculifera in its ochreous colour, which is sometimes a little derufata. 
reddish yellow, only the abdomen being red. The reticular lines are finer, more regular, more forming short 
dark brown streaks. Especially distinct on the hindwing, where the dark submarginal line is entirely absent. 
The cellular spot is composed of 2 contiguous small round spots. 29 mm. Described according to 2 dd from 
Parana, but it occurs also in other parts of Brazil. Dyar states that the apex of the forewing is tinged with 
dark violettish brown as far as vein 6; it is so as far as vein 4. A vertical submarginal line extends from the 
anal angle upward to vein 4. 
D. innubila W arr. resembles a derufata (173 b) with a very pale marking. According to the author, innubila. 
it is distinguished from speculifera by its darker, more uniformly copper red colour, for which reason the reti¬ 
cular lines are less distinct. The lower half of the broad main band are somewhat narrower. The apical area 
behind the oblique submarginal streak is broader and darker red, not clouded as in speculifera and derufata. 
Hindwing with 2 small dissimilar hyaline spots. 26—28 mm. Bolivia, Peru. 
D. acrotoma Dyar. Reddish, the striation blackish. The main band on the forewing narrow, triangu- acrotoma. 
larly widened at the costal margin. A straight line through the apex from the costal margin to vein 4. Behind 
it apparently not dark as in innubila. Hindwing with a faint median shadow. The discal spot is composed 
of 2 small hyaline spots, from where a line extends to the inner margin. The marginal striation is distinct, 
with wide meshes. 28 mm. Described according to 1 specimen from Zacualpan (Mexico). Differences from 
innubila not mentioned. 
D. flagrata Wkr. (— floridana Hulst.). According to Warren, the species is not identical with speculi- flagrata. 
fera (143 b) as Hampson presumed. The inner margin of the forewing is dark brown from the base to the main 
band. The latter is not broad, not strangulated in the middle as in speculifera. but at- the costal margin it forms 
an almost square spot down as far as vein 5, and from its interior angle a dark oblique line extends to behind 
the middle of the inner margin, while an irregular line extends from the exterior angle to the anal angle. The 
cellular spot on the hindwing is divided, bordered outside by the black median line which is widened into a 
spot above the median vein. Under surface pale brown, the marking olive brown, the interior marginal half 
of the hindwing broadly yellowish. The reddish yellow ground-colour of the q is covered in the $ by dark 
brown dusting on both wings. 26—32 mm. Venezuela. Colombia, Ecuador. 
3. In the following species the median band of the hi n d w i n g is not 
forked. The striation is parallel. The hyaline spot on the hindwing 
varies in its shape. 
D. nomima Dyar. The main band on the forewing is convex outside, distinguishing the species from nomima. 
the two following ones. Ground-colour dull orange slightly mixed with red. with fine reticular lines. The 
main band is widened at the costal margin. A fine transverse line at the apex and a short vertical one at the 
anal angle. Also the hindwing shows the median band broader at the costal margin, without any other con¬ 
trasting lines. Only a single small white median spot. 22 mm. Described according to a single specimen from 
Vera Cruz. 
D. Ihieata Drc. (169 a). Body and wings olive brown. Forewing with 2 narrow somewhat darker bands lincafa. 
in the basal area. The exterior band is twice as broad at the costal margin as at the inner margin. Traces of 
a subapical band from vein 4 vertically to the costal margin. Hindwing with a large hyaline spot in the middle, 
a few punctiform ones between it and the inner margin. 24 mm. Mexico. 
D. borro Dyar differs from lineata in 2 small white hyaline spots on the hindwing. Forewing dark harm.
