HEORTA; THEROA; EUHYPARPAX. By Dr. M. Drattdt. 
14. Genus: Heorta Wkr. 
Distinguished from the preceding genus by the shorter and broader wings with a rounded distal margin 
and sharp apex; the neuration is the same as that of Pentobesa except vein 6 arising a little above the upper 
cell-angle from the accessory cell, and besides the costal branch of the hindwing arises from the centre of the 
subcostal branch; in Pentobesa farther at the cell-end. 
Type of genus: H.roseoalba Wkr. 
roscoalba. H. roseoalba Wkr. is a pure white insect, the marginal area is slightly tinged with pink, the veins 
finely striped pink, and two notched broad pink transverse stripes, the anterior stripe is distally angular in the 
cell and on the submedian fold. Hindwing white with pink fringe. This pretty and considerably deviating 
Notodontid species has been described from Brazil. 
cilia. H. cilia Dogn. (oculata Dogn., mitis Sells.) (144 c). The olive green ground-colour is dusted with red- 
brown in some places, the <$ is more intensely strewn with black, with double black transverse lines, the 
posterior one being dotted white; a blackish oblicpie shadow extends from before the centre of the costal margin 
towards the anal angle which it does not reach, stopping before a thick black dot. Hindwing greyish-brown, 
lighter and more yellowish towards the base. Colombia, Bolivia, Brazil. 
viridans. H. viridans Dogn. (144 c) is very similar to cilia, slightly larger on an average, with broader wings, 
lighter olive green, less intensely strewn with dark, with more scanty and finer markings, so that the black dot 
above the anal angle is more conspicuous. Hindwing somewhat lighter. Bolivia, Brazil. 
car cm a . H. carema Schs. is smaller than viridans, the reddish-yellow ground is mixed with olive green and 
shows a large triangular brown area mixed with lilac, green and white, edged by the two velvety brown double 
transverse lines which are united above the centre of the inner margin; two dark brown spots are before the 
upper distal angle of this area; a black subterminal shadow is dusted with white distally. Hindwing dark brown. 
Expanse of wings: 27 mm. French Guiana. 
15. Genus: Theroa Schs. 
This genus had been originally established for the only species zethus, but it was cancelled again, and 
zethus ranged with the genus Litodonta; I leave the genus in its original form and range zethus as the type of it. 
Vein 6 of the fore wing arises from the upper cell-angle, in Litodonta from the centre of the areole; the two lower 
subcostal branches arise on a rather long stalk from the end of the areole; vein 5 arises far above the centre 
of the cross-vein, about midway between the ujDper cell-angle and the centre of the cross-vein, in Litodonta 
rather exactly from the centre of the cross-vein. The lower larger half of the cell is quite open, only the upper 
short portion is closed and extends rectangularly to the subcostal vein; the costal vein arises directly from the 
upper cell-angle; vein 3 arises separated from 4, 5 is very feeble, 6 on a long stalk with the subcostal vein. 
The cross-vein on the hindwing of Litodonta is closed altogether, although the lower, very oblique part is feeble, 
the costal branch arises far before the cell-end. Only 1 species: 
Type of the genus: Th. zethus Drc. 
"dints. Th. zethus Drc. ( 144 c) is light whitish lilac grey on the forewing, strewn with brownish, the two median 
transverse lines are marked by rows of vein-dots edged with whitish, a red-brown reniform macula centred 
with reddish-brown is at the cell-end, and an antemarginal row of small red-brown internerval spots edged with 
reddish-yellow distally, then narrowly with red-brown. Hindwing of B whitish, smoky at the margin, of $ 
brownish-grey, somewhat more whitish towards the base. Mexico. 
16. Genus: Kuhyparpax Beut. 
This genus contains but one North-American species the <$ of which has the antennae not pectinated 
to the tips and very short palpi. Forewing very slightly concave in the middle of the costal margin, the areole 
is very narrow and short, the other neuration very similar to that of Heorta. The costal branch of the hindwing 
arises near the cell-end. Only one typical species. 
Type of the genus: E. rosea Beut. 
•rosea. E. rosea Beut. (144 c) is easily recognizable by yellowish pink forewings with a very indistinct darker 
curved postmedian line: traces of a yellowish spot are at the cell-end. Hindwing pink with lighter fringe. This 
rare species is only known from Colorado so far.
