E. iridescens sp. n. (22 b). Eorewing reddish-yellow, with a brass lustre, coarsely and densely strewn 
with a brownish black and extensively strewn with silvery bluish-violet, particularly pure in the filling of the 
black, double, dentate transverse lines and between and behind the 3 maculae which are thickly encircled with 
black; before the lilac-white undulate line with a larger spot at the anal angle there are black sagittae, the 
largest and at the same time that which projects the farthest towards the margin is on the discal fold. Hind¬ 
wing brownish-grey, towards the margin darker. 1 couple from Mt. Tolima (Colombia). — aeruscans form. nov. 
(22 b) from Bolivia (Cuesta de Cillutincara), of which there is also 1 couple before me, is of a much more mono¬ 
tonous colouring, of a purer brass-colour with a slight olive tint, without the coarse black strewing, much more 
finely marked and instead of the bluish-lilac colour only somewhat dusted with lilac-grey. In both forms these 
bright colours appear only in an oblique light, from above they appear to be plainly greyish-brown. 
E. tenebrosa sp. n. (22 b) resembles albitorna (22 a, b), but it is much darker and without the white 
anal spot; the reniform macula is narrower, but below it exhibits distally the same white dot; in the distal third 
of the costal margin there are 4 small snow-white streak-shaped spots; the single dentate transverse lines 
are on the averted sides hardly noticeably lighter, bordered with a more yellowisch colour, the undulate 
line is entirely absent. Hindwing dark blackish-brown. 1 couple from Colombia (Pacho and the Quindiu Pass). 
29. Genus: Ursogastra 8m. 
We mention this genus here only, because it is enumerated as a genus in the North American catalogues. 
In our opinion it coincides with the genus Eriopyga, and it is identical with the group of species fuscibarbata 
to excavata (p. 135), which is distinguished by thick hair on the middle femora and tibiae and long lateral hair- 
tufts on the abdominal sides, meeting each other, as they are bent downwards, on the centre of the ventrum. 
The cell of the forewing beneath exhibits fine hairing turned more longitudinally than downwards. The only 
species to which we add yet a doubtful form, would thus be best arranged at the said place as a subordinate 
genus. 
U. lunata 8m. (22 c) has reddish-grey forewings with double interrupted transverse lines and between 
them the very characteristic, deep velvety brown coherent macular marking which is well recognizable from 
the figure; the anterior transverse line is very obliquely situate and ends in the centre of the proximal margin; 
the light undulate line is on both sides bordered with brown and runs almost straight parallel to the distal 
margin. Hindwing dull smoky grey. Found in Arizona. — The occurrence of this otherwise cpiite isolated 
species in the Colombian Central Cordilleras (Quindiu Pass), from where a very fine 8 taken by Fassl is before 
us, seems to be most remarkable. As Fassl has otherwise most conscientiously and carefully labelled his speci¬ 
mens, it cannot be assumed to be an error, particularly since the insect differs in several marks, so that it might 
be a different species: quindiensis form. nov. (22 c) exhibiting more squat wings with a less sharp apex; the colour 
of the forewing is a very light whitish grey, in some places finely strewn with chestnut-brown, the most intensely 
in the concavity of the macular spot at the costal margin; the anterior transverse line runs very little obliquely, 
the distal part of the posterior line consists of black dots on the veins, whereas the proximal part is more or 
less red-brown and coherent; the marginal area is somewhat darker olive-grey in which the undulate line is 
prominent as small light internerval spots proximally bordered with red-brown, thus cpiite different compared 
to lunata where besides the marginal area is only darkened in the upper half in a broad triangular shape and 
a lighter costal-marginal triangle appears at the apex of the wing. Fringes deep red-brown. 
30. Genus: Eriopygodes Hmps. 
Distinguished from Eriopyga by the thorax being covered with predominantly pure hair, with distinct 
loose tufts on the prothorax and metathorax; besides the hairy cover of the second palpal joint is longer. America 
has only one representative of this otherwise eastern genus. 
E. grammadora Dyar entirely resembles a Cirphis (p. 163): forewing loam-coloured yellowish with 
blackish-striped veins and folds and more brownish-red tinted fringes, both on the head and collar. Hind¬ 
wing black with light reddish fringes. Abdomen above black with an ochreous-yellow anal tuft and a brownish- 
red ventral side. Expanse of wings: 33 mm. Described from Mexico. 
31. Genus: Uiephelodes Gn. 
It shows quite the same marks as Eriopygodes, but the abdomen is covered with tufts above on the 
rings. They are larger species with partly very strongly combed antennae, half a dozen being known now, all 
of which are very similar. Hampson connected with this American genus the East Asiatic genus Monostola ,
