tuberculale, with two transverse impressed lines, of which the hinder one is 

 curved ; fore border and hind border rounded; sides nearly straight. Ovi- 

 duct M;ick towards the lip, about half the length of the abdomen. Le^s 

 thick; fore femora with one row of very minute spines; four posterior 

 femora with two rows of spines, those on the middle femora very small ; 

 hind femora about two-fiflhs of the length of the fore wings; tibia3 with 

 very minute spines; hind tibiae with no spines on the two upper keels. 

 Fore wings lanceolate, rather narrow, a little longer than the hind win^s ; 

 three rows of areolets between the costa and the scapular vein; first row 

 not extending far from the base of the wing; second and third not ex- 

 tending to the tip; second of irregular areolets ; a few areolets in the third 

 large, each including some smaller aveolets; externo-medial vein parting 

 from the scapular in the middle and including with it several small exterior 

 areolets ; one row and beyond the middle two rows of areolets between the 

 externo-medial vein and the interno-medial, each areolet including some 

 smaller irregular areolets; two hinder rows of areolets, those along the 

 interior border very numerous. Hind wings pellucid ; veins pale green ; 

 transverse veins white. Length of the body 19 lines ; expansion of the fore 

 wings 56 lines. 



The externo-medial vein emits its chief branch after it parts from the 

 scapular; in P. neriifolia, P.fenestratus and P. uninotatus it emits the 

 branch much nearer to the base of the wing. The transverse veins are less 

 numerous and more irregular than those of P. venosus.
