Type testacea Wlk. Description from vubviiincia. 
<$, £. Proboscis rudimentary; palpi upturned, reaching above vertex of 
head; first joint rather short, curved; second joint about two times first joint, 
nearly straight; third joint small, about half of first joint, somewhat pointed; 
all joints covered with hairs and scales in front, with hairs at sides and above; 
eyes large, suboval, smooth; antennae over half of costa, bipectinated in 
simple in $ ; pectination about three times shaft, gradually getting shorter 
towards tip, pecten ciliated at tip and on anterior side; first joint of shaft with 
hairs and scales in front, forming a short tuft; fore tibia with a process shorter 
than tibia, somewhat broad at middle and roundly pointed towards tip; 
femurs of fore leg moderately covered with hairs and scales ; mid tibia with two 
spurs, longest about half the length of the tibia, outer spur about ^rd shorter; 
hind tibia with four long spurs, shortest about |ud of tibia and on the outer 
side, inner spurs about half as long; all spurs acuminated terminally and 
covered with hairs and scales ; femora and tibiae of all legs covered with hairs 
and scales; tarsi with scales and some spines on inner side. Fore wing lather 
broad; costa somewhat arched; apex rather acute; termen nearly erect, 
rounded from vein 4; tornus well rounded; inner margin nearly straight; 
ib indistinctly forked at base; 2 from about Jth lower median; 3 from frd 
2 to 4; 4 from lower angle ; 5 from middle of discocellulars, which are oblique 
outwardly; 6 from upper angle of cell; 7, 8, 9, 10 stalked 1 , and from well before 
upper angle; 7 from about half of 10; stalk of 8, 9 from fth of 10; 9 very short, 
from beyond free half of 8; 11 from about fth upper median; 12 parallel to 
costa. Hind wing sub-triangular; costa curved; apex, outer margin, tornus 
and inner margin well rounded ; 1 a and 1 b nearly straight ; a small rounded 
lobe at ib) 2 from frd lower median; 3 from frd 2 to 4; 4 from lower angle; 
5 rather weak and from middle of discocellulars which are oblique outwardly ; 
6 and 7 stalked for over frd of 6 and from upper angle ; 8 upcurved from base, 
then downcurved to upper median at beyond half, before half of upper 
median traces of an oblique bar, then curved upwards to costa and ending 
near apex. 
The absence of the areole in P. rubritincta must be considered as an excep- 
tion in this genus, caused by the two long sides of the areole having become 
anastomosed and this species should thus be regarded as the most highly 
developed species in the genus; it is further peculiar that vein 10 is given off 
beyond the areole, which is the case in the Indian and African species when the 
areole is short; in the Indian and African species that have the areole long 
vein 10 is said to come from the areole. 
1 In P. rubrifascia an areole is present, which is very long, over half of vein 10, 
and narrow; 6 comes from areole near base; 7 from just before end of areole; 8, 9, 10 
stalked from end of areole ; 9 from 8 at beyond half the distance end of areole to outer 
margin; 10 slightly stalked with 8, 9. 
In P. flavida, which is unknown to me from specimens, the areole is said to be 
present also, but it is short and 10 comes from beyond the areole.
