and distal-marginal areas, with a vertical row of blackish, outside white spots. Observed in Costa Rica, Co¬ 
lombia (Western Coast), Peru, Minas Geraes (Uberaba), Rio de Janeiro, and on the Itatiaya. 
Cincinnaia- group. 
Three closely allied and similar species, but easily discernible by certain marks. 
P. cincinnata Dogn. (163 g). The type of the Washington Museum is in an extremely bad condition, 
the abdomen does not belong to the specimen, but according to Heinrich it proved to be that of a Noctuid. 
Nevertheless, the species can be reconstructed by aid of a ^ of the Tring Museum, originating from Bolivia 
like the type. The dark brown basal area with an indistinct black cellular spot consists of curled hair. It is 
distally bordered by an indistinct whitish vertical line which widens much towards the apex at vein 5 and 
contains several blackish streaks between veins 5 and 9 on the whitish area. The distal margin of the fore¬ 
wing is otherwise brown, the veins are somewhat darker. The contours of the distal margin are almost straight. 
Hindwing brown, with blackish veins. $ unknown. Bolivia. 
P. proiecta sp. n. (163 g). The dark brown basal area of the forewing, broadly darkened at the costa, 
is composed of short scales. It is pierced outside from the inner margin to vein 5 by white veins and followed 
by an indistinct whitish vertical line and, from there to the costa, it runs back inwards roundish, likewise with 
an indistinct white zone outside. The distal margin is distinctly convex. An apical black spot on vein 7 in 
the light distal-marginal area, and an indistinct row of dark spots from the angle to vein 5. Hindwing light 
brownish, somewhat darkened at the inner margin. £ unknown. Peru, Carabaya (Ockenden). Type in the 
Tring-Museum. 
P. guaya Schs. (163 g). The dark brown distal-marginal area of the forewing with an indistinct cellular 
spot is formed of curled hair. It is bordered outside by an indistinct, costally more inward whitish vertical 
line which widens much at vein 5 towards the apex and contains four oblong black spots between veins 6 and 9. 
The distal margin is distinctly convex. The distal-marginal area is slightly covered with brown curled hair 
which is not to be found on the two other species. Hindwing whitish. forewing completely covered with 
curled hair, the white postmedian line is outwardly dentate in the inner-marginal part. Hindwing dark brown. 
Minas Geraes and Paraguay. — The species varies much in size, but its marking and colouring is constant in 
long series. 
P. bolivari Heyl. ( Pentophera) (= Meg. pellucens Dogn., Unduzia gistinda, phaule Dyar) (163 g). The 
species differs extraordinarily in the male and female sexes also in its extern? 1 appearance. The A is quite 
black, the wings hyaline, without any markings, with a black costa. $ considerably larger, from light brown 
to dark brown, head, thorax, abdomen and legs greyish brown, wings semihyaline, the forewing with a vertical 
postmedian row of whitish spots. Mexico, Panama, Colombia, Venezuela, Peru. 
P. dyari Joic.ds Talb. Only the $ is known. It is much larger than bolivari blackish hyaline like 
the of bolivari. The black thorax bears two tufts of purely white hair in front and a small one at the base. 
The wings are longer and narrower than in bolivari. The forewing exhibits one small heap of white scales each 
between the veins 5, 6 and 7, near the base. Legs black, beneath with a distinctly defined row of white hair. 
Ecuador. 
III. Aidinae. 
The male Aidinae are provided with broadly plumose antennae feebly dentate in the terminal parts, 
while the antennae of the $$ are thicker, plain in the basal parts, thinner and feebly dentate in the terminal 
parts. In both sexes, the precostal vein of the hindwing extends freely and is connected at most with the cell 
by a cross-vein. The cross-vein is situate more basad in Aidos and therefore smaller, or entirely absent, while 
in Xenarchus it extends obliquely forward to the precostal vein and is somewhat longer thereby. The Aidinae 
are more specialized by these characters than other Megalopygidae. The organisation of the appendages of 
the 10th ventral segment in the approximates Trosia with which they are also allied by the red colouring, 
but also the Mediterranean genus Somabrachys the larvae of which may be allied to those of the Aidinae. For 
the flat dorsal and subdorsal foveae of the larval ventral segments, on the bottom of which there are two rows 
each of divaricating short bristles, remind us of the skin-bags subdorsally developed in the larvae of the Soma¬ 
brachys, which are filled with loose bundles of short black-hyaline spines. In the neuration, the Aidinae differ 
besides from the other Megalopygidae in the posterior half of the cell of the hindwdng being produced into a 
long point terminating into veins 3—4 near which also vein 5 arises. This formation reminds us of some Lima- 
codidae to which several authors formerly placed the Aidinae.
