P. bistellata Dgn. (69 g). Forewing blackish-brown, with a white basal streak behind the cell, a bistellata. 
white discal and subapical spot. Hindwing black with a large oblong white cellular spot extending yet beyond 
the cell. Expanse 28 mm. Argentina. 
P. vidua Warr\ differs from bistellata (69 g) in the veins of the forewing being white or yellow, and vidua. 
the white central spot of the hindwing being much more extensive. Peru. 
P. fuliginosa Dgn. (69 g). Wings diaphanous greyish-black, veins of forewing yellow. On the forewing fuliginosa. 
a white spot behind the cubitus, as long as the cell, two small spots distally to the cross-vein; hindwing with 
3 similarly situate spots, and the cell partly white; hindwing beneath about two thirds white. Expanse 
26 mm. Bolivia, Peru. 
P. mara sp.n. (69 g) is similar to fuliginosa, in the forewdng the veins are darker, black; only the mara. 
white spots behind the cross-vein are present. Hindwing only behind the cross-vein very indistinctly lighter. 
Forewing beneath as in fuliginosa above, hindwing with a thinly whitish-irrorated basal stripe in the cell 
and a similar one behind the cell as far as 4 / 5 of the wing. Expanse 21 mm. Peru. $ type from Vilcanota 
in the Berlin Museum. 
P. dynastes sp. n. (69 g). Forewing blackish-brown, veins and a large subapical spot orange, a spot dynastes. 
behind the cross-vein hyaline. Hindwing black with a yellowish-white median band which anteriorly does 
not extend beyond the 1st median, so that the base, costal margin and distal margin remain broad black. 
Hindwing beneath yellow, only the distal margin broad black, at the 2nd cubitus proximally projecting. 
Expanse 34 mm. £ type from Novo Friburgo in the Berlin Museum. 
16. Genus: Plirygani«iia Pack. 
Closely allied to Polypoetes, but the cell of the forewing longer, wings more scantily scaled. The 
only nearctic genus of the family. The larva of Ph. californica, by its habitus, resembles a Noctuid larva, 
it is bare and possesses an enlarged 12 th segment ; the anal feet are less chitinous than the ventral feet 
and divergent. 
Ph. californica Pack. (69 h). Wings light grey, veins darker, behind the cross-vein of the forewing, californica. 
often indistinct, three yellowish spots. California. 
Ph. naxa Drc. (69 h). Wings less coarsely haired, more elongate, forewing brown, hindwing black, naxa. 
Guatemala. 
17. Genus: StenopSastis Fldr. (Momonipta Warr.). 
In the habitus similar to Polypoetes in which, however, the antennae are distinctly combed, whereas 
in Stenoplastis each antennal joint only has a projection set with hair-pencils. 
St. persimilis Dgn. Forewing pale brownish-black, in the basal half in the cell and behind it with persimilis. 
hyaline spots, a hyaline spot distally to the cross-vein, extending from the veins 3 to 11, veins for the great¬ 
est part yellowish, beneath only at the margin and at the radial fork. Hindwing white, with a broad black 
marginal band, but on vein 3 a white indentation, only the fringes black. Expanse 31mm. Colombia: Tolima. 
Sf. semisocia Dgn. resembles the following, the white area of the hindwing is smaller. Forewing black, scmisocia. 
veins yellow; white are a basal cellular spot, another between the posterior edge of the cell and axillaris, 
an oval one distally to the cross-vein, a subterminal line, most distinctly prominent between the two cubital 
branches. Hindwing black, cell hyaline white, which colour extends from the cubital fork to the subcosta. 
Forewing beneath uni-coloured pale black, veins not yellow, no subterminal line. Expanse 25 mm. Colombia. 
St. jipiro Dgn. Forewing brown with yellowish veins, a whitish-hyaline spot in the cell, at about jipiro. 
1 '3 of it, another behind the cross-vein, a third on the axillaris, distally to the cellular spot, anteriorly 
touching the cubitus, and some submarginal crescents. Hindwing white with a broad black distal margin 
which is not narrower towards the tornus, but broader on the 2nd cubitus towards the base. Ecuador. 
St. psllucida Dgn. (69 h) is like jipiro, the markings of the forewing smaller and much more contrast- pellucida. 
ing. Colombia. Very similar to Polypoetes trimacula Warr (69 g). 
St. empheres Prt. Similar to pellucida (69 h), but the cellular spot of the forewing is less distinct empheres. 
and more extensive, a yellowish-white basal spot behind the cell, a yellowish subapical spot is mixed with 
white, the spot behind the cross-vein is smaller, the distal margin of the hindwing posteriorly narrower. Ex¬ 
panse 30 mm. South East Peru. 
St. opaca sp. n. (69 h) corresponds with empheres in the black distal-marginal band of the hindwing opaca. 
being much narrower towards the tornus. In the forewing all the light spots are reduced, greyish-hyaline, 
scarcely distinct. The spot at the hind-margin consists here only of two minute dots before and behind the 
analis, the spot at the radial fork is orange like the veins, the cellular spot almost extends to the base.
