The black hair-spots at the tips of the veins, the relative 

 positions of the forks of the 2nd and 4th longitudinal veins, and 

 the coloration of the tarsi are constant. The 2nd longitudinal 

 vein forks before * the base of the 3rd vein ; the anterior branch 

 of the 2nd vein forks before the middle of the wing and a little 

 beyond the fork of the 4th vein. There are no white hair- spots 

 in the fringe of the wing, nor on the absolute margin of the wing 

 (at or very near the tips of the veins) as in typical margininotata, 

 which character alone is almost sufficent to distinguish the two 

 forms. The whole wing has a more brownish appearance, without 

 the variegated appearance of P. margininotata, and the absence of 

 the white fringe at the wing-tip will at once identify it from that 

 species. A second good character that I believe separates it 

 from all other Oriental species is that the whole of the tarsi are 

 milk-white. In the allied species, P. margin inotata, P. gilvipes, 

 P. proxima and P. mivta, some portion of the tarsus is always 

 black, often the major portion.

A specimen in the Indian Museum, taken by Dr. Annandale at 

 Quilon, Travancore, 9. xi. 08, has the hairs of the body, on the 

 tibiae and metatarsi (except the tip of the latter) darker brown, 

 also the lower branch of the 2nd longitudinal vein runs almost 

 directly to the wing-tip. The blackish hair-spots on the disc of 

 the wing, on the fork of the anterior branch of the 2nd vein, and 

 on the fork of the 4th vein, are well marked. The original three 

 specimens (females) were taken at Kurseong 4. vii. 08 by Dr. 

 Annandale.

$ . Considerably resembling P. margininotatn, but smaller, the 

 general colour of the long hairs of the thorax and abdomen more 

 brownish grey. The wings resemble those of that species, with 

 a tendency to dark spots placed irregularly, but generally at the 

 bifurcations of the veins. The distinguishing character is the 

 absence of white hairs at the wing-tip and of white hair-spots on 

 the margin of the wing, also of isolated small patches of erect 

 white hairs on the veins. Another good character is that the 

 2nd longitudinal vein forks beyond the origin of the 3rd vein, 

 instead of before it as in P. margininotata . The anterior branch of 

 the 2nd vein forks a little before the middle of the wing, and a 

 little beyond the fork of the 4th vein. The legs have the tarsi 



* This is the case in the original type specimen (a female). In a second 

 specimen the pubescence obscures a vein of the base of the wing. In a specimen 

 mounted lor the microscope, the 2nd vein forks beyond the base of the 3rd, 

 and for this reason it is doubtful if it is of this species.
