E. tolumnensis H.-Schdff. (= hirsuta Wlcr.) (16 e). Body black. Palpi and antennae at the tips white, tolumnen- 
Collar spotted white, legs striped white. Wings with a green lustre and with large yellowish hyaline spots, on 
the forewing in and below the cell, and an oblique row of 5 spots behind it between the lower median and 5th 
subcostal vein; at the base there are 2 subcostal, ochreous-yellow stripes. Hindwings subcostally and below 
the cell with white hyaline stripes, in the cell and behind it yellow hyaline spots. The inner-marginal area black 
without a green lustre. Expanse of wings: 50 mm. Colombia (Bogota). 
52. Genus: Xantlioinfs Bmps. 
Characterized by long, roughly haired, porrect palpi, the woolly-haired thorax and abdomen, and the 
antennae being thickened behind the middle, in the $ serrate-dentate. On the hindwings the lower median 
vein and lower radial vein rise unpetioled from the cell, the first median vein from the lower one shortly before 
the border. 
H. grandis Druce (16 f) is an uncommonly characteristic, rather large species, being above bright grandis. 
orange, beneath black. The border of the wings is narrow at the apex of the forewing and round the proximal 
angle, on the hindwings broadly black. From Costa Rica; before me there are also specimens from Panama 
(Chiriqui). 
53. Genus: Hysti aea Wkr. 
Very large, robust animals with brown wings being decorated with yellow and red spots and metallic 
blue dots. On the forewings the upper radial vein rises below the upper cell-angle, just like on the forewings, 
too; here the discocellular is very large, from its lower corner the lower median and the lower radial vein rise 
unpetioled. The centre of the range is the Amazon District; only few species reach the southern parts of Central 
America. 
H. paulina Wkr. (16 f) is not to be confounded with any other species by the dense hair on the upper paulina. 
surface of the $ hindwings, leaving free only the marginal part. Otherwise like the following from which 
it differs by the abdomen, which does not exhibit a blue lustre posteriorly and shows only lateral blue spots. 
The orange-yellow oblique band of the forewings is much broader, the carmine stripes being more distinct and 
extending farther towards the margin. The hindwings are quite dark brown. Expanse of wings: 70 mm. Brazil 
(Sao Paulo). 
H. imaon Hmps. (16 f) is easily recognizable by the pecidiar shape of the hindwings being almost imaon. 
quite brown, only a very minute red spot is situate at the border above the lower median vein. The forewings 
exhibit a narrow, orange-yellow band behind the cell and narrow, subcostal and submedian red stripes as well 
as above vein 1. The brown abdomen is posteriorly quite metallic blue. Amazon (Surimaya). 
H. hoffmannsi Rothsch. (16 g) is somewhat allied to imaon and is at once discernible by the large hoffmannsi. 
orange-yellow distal-marginal spot on the hindwing, the proximal half of the forewing being almost quite red, 
by the broader yellow postdiscal spot and the brown, not metallic blue abdominal end. Brazil (Rio Madeira). 
H. meldolae Btlr. (= bellatrix var. Wkr.) (16 g) differs from bellatrix, particularly the form aucta , meldolae. 
which it approximates greatly, by the very extensive spread of the red colour on the forewings; furthermore, 
the two upper spots of the yellow postdiscal macula small, the two lower ones large and moved more towards 
the margin. In Panama, Venezuela and Trinidad, apparently not rare. 
H. bellatrix Wkr. (16 f) exhibits on the blackish-brown body metallic blue spots on the forehead, 
neck, collar, metathorax and at the abdominal sides beginning from the 3rd ring. The base of the shoulder- 
covers and the two first abdominal rings above cream-coloured. The four pale yellow postcellular spots are 
arranged in one row. In the typical form the forewings are coloured exactly like in amazonica. ■ —- f. columbiae 
Btlr. has a considerably larger yellow postdiscal spot, the red spots on the hindwings stay separated, the yellow 
of the proximal margin is greatly reduced. -—- In f. aucta form. nov. (= ab. 2 Hmps.) (16 g) which is before me 
from Muzo, the red colour is broadened from the median to the proximal margin and parted only by the black 
vein 1. In the specimen before me there is besides a yellow cuneiform spot in the base of the cell of the forewing; 
on the hindwings the red spots are larger and broadly flown together. — From Colombia (Bogota) and Venezuela 
(Aroa). 
H. cepheus Cr. (16 g) is characterized by 3 yellow abdominal rings which are dorsally interrupted; cepheus. 
the under surface also shows a yellow band at the 4th segment; laterally there are metallic blue spots. Forehead, 
shoulder-covers and forehips usually with yellow spots. Forewings with a metallic blue spot at the base and 
2 at the transverse vein; short carmine stripes are at the base below the costa and median as well as at the 
bellatrix.
