perhaps the most closely allied to the Euchaetias- group and the larva may prove it to he alien to the Phego-p- 
terini. Characteristic marks are: a pointed frontal cone, a very feeble proboscis, and short, projecting palpi. 
In the forewing the 1st subcostal vein rises shortly before the upper cell-angle, the 4 others have a long, common 
footstalk. The upper discoeellular is of medium length, the middle one bent in angularly, the lower one short. 
All the veins are present in the hindwing. 
G. strigillata Rothsch. (49 h). Blackish-brown, collar and metathorax, as well as chest orange, forewing strUjillala. 
with numerous, silvery white transverse striae. Carabaya (Peru). 
80. Genus: Hyalarctia Hmps. 
This genus contains 2 pale yellow butterflies of an Halisidota- like habitus. On both wings the upper 
median vein branches off far before the lower cell-angle, the two lower radials come from the lower cell-angle 
itself, the upper one with the subcostal resp. with the pedicle of its 3 last branches from the upper cell-angle. 
On the forewing the two first subcostal veins rise from the upper cell-wall. 
H. tepica Dyar (48 g) is before me only from Mexico. Wings cpiite unicolorously pale yellow, head lepira. 
orange, body tinted orange. Rare. 
H. sericea Schs. is somewhat more robust, but of the same expanse of wings, likewise cpiite pale sericea. 
yellow, diaphanous, somewhat silky lustrous, with darker veins; at the base of the forewing a small orange 
spot; the dark dots on the patagia a little more distinct. Castro, in the Brazilian State Parana. 
81. Genus: Psendopharus Hmps. 
Almost exactly like the preceding genus, on the forewing the 2nd subcostal vein also rises from the 
upper cell-wall, and all the discocellulars are strongly angled like in Hyalarctia, but on the hindwing vein 5 is 
absent and the upper median vein rises with the lower radial from the lower cell-angle. 4 species are known. 
Ps. domingona Drc. (48 g). By the white spots on the patagia it somewhat recalls Opharus bimaculata domhujona. 
(56 g), of which it has also the sooty blackish-brown forewings, diaphanous white hindwings, and posteriorly 
orange abdomen; but the abdominal bands are not separated into lateral spots by a dorsal line, and beside 
the two white patagial spots there is a third on the metathorax. Peru. 
Ps. hades Dgn. Size and colouring similar to the preceding, but the whole marginal half of the hindwing hades. 
sooty dark. Abdomen with only very narrow orange bands, otherwise blackish-brown. From Mt. Tolima in 
Colombia. 
Ps. Cornelia Drc. (48 g). Likewise greatly approximating the preceding, hinclwing only in and round comelia. 
the cell diaphanous whitish, abdomen with orange-yellow dorsal bands and lateral spots. Peru. 
Ps. amata Drc. Somewhat larger than the preceding (50 mm), head and thorax sooty black, and amata. 
the abdomen above with orange transverse bands. Forewing deep olive-brown, suffused with a dark brown, 
particularly towards the margin. Hindwing black, in and round the cell somewhat more diaphanous, but not 
white as in the preceding. Venezuela. 
82. Genus: Metacrisla Hmps. 
This genus in its habitus already approaches the Halisidota, but the whole body, particularly tibiae 
and femora of all the legs, are very strongly haired. Proboscis strong, palpi projecting directly forward, the 
terminal joint not stunted. Head and thorax densely and long haired. The two first subcostal veins rise separately 
before the upper cell-angle; out of the latter rise, from the same place, the footstalk of the 3rd to 5th subcostal 
veins and the uppermost radial; the upper median branches off somewhat before the lower cell-angle; the same 
is the case on the hindwing, where all the veins are present. They are alpine animals, adapted to a more rough 
climate, nothing is known about the larvae. 
M. schausi Dgn. (57 f). Head and thorax chestnut-brown, abdomen dark yolk-coloured. Forewing schausi. 
in the median area chestnut-brown with yellow spots in and below the cell, marginal and basal areas pale yellow 
with royal yellow embedmends, the border between the basal and median areas is formed by a distally convex 
bow. Hindwings of a paler yellow. Quindiu Pass (Colombia). 
M. courregesi Dgn., known only from Loja in Ecuador, is similar but more unicolorous, the median courregesi. 
area of the forewing not so prominently dark; the border between the light basal area and the median area forms 
an acute angle with a distally directed vertex, situate in the middle of the cell.
