the hind femora, tips of tibiae and tarsi yellowish. Abdomen 

 black, with grey pilosity ; the appendices brown or yellow, 

 with brown villosity. 



Forewings with the nervature pale yellow, spotted with 

 dark grey. The costalveins all furcated and connected by 

 transverse veiulets, so that the costal aera consists of a row 

 of small anterior and a row of larger posterior cells. In Ps. 

 zebra the anterior row is the larger one. The black point 

 at the junction of subcosta and radius, so characteristic for 

 zebra, wants; in the posterior wings, however, the end of 

 the radius is somewhat darker. 



There are in the forewings about 5 larger grey spots 

 along the radius, the other larger ones are arranged in 

 3 transverse lines on the disk of the wing, and there are 

 also many small spots on the border, especially on the 

 external one. Hindwiugs unspotted, only with the apex and 

 hindborder spotted with grey. Nervature yellow, the tip of 

 the subcosta excepted which is brown. One row of trans- 

 verse nervules on the disk, forming a somewhat curved line 

 from the tip of the radius to that of the cubiti. 



The app. sup. (Fig. 2) are relatively longer than in P. zebra 

 (Fig. 1), more slender, with the apex curved upwards
