but in other respects it seems to approach very closely

Platyptilus petrodactylus. 



(PLATE II. FIG. 15.) 



Pterophorus petrodactylus,, Walker, Cat. Lep. Het. xxx. pp. 940, 941 , 

 nee petradactyla, Hiibn. Eur. Lep. 37, 38. 



The fore wings are white, shaded with cinereous or 

 ashy-brownish scales, especially about the base 

 and towards the costa ; the costa itself is brownish 

 beyond the middle ; an oblique brownish-fuscous 

 dash comes from the costal cilia above the fissure, 

 starting from before the apex and pointing in- 

 wards more obliquely than the apical margin. 

 This dash is widest on the costa, tapering to a 

 point inwards, and is much darker, more fuscous, 

 at its lower portion. There is a cinereous shade 

 towards the apical margin, with a cinereous line 

 in the white cilia near their bases. The cilia 

 within the fissure are white, at the anal angle 

 shaded with fuscous ; there are no spots in the 

 pale cilia of the dorsal margin. 



Hind wings very pale cinereous ; cilia very slightly 

 darker toward the points of the lobes. 



Legs and body shaded cinereous ; the spurs apparently 

 equal ; the joints scarcely thickened. 



Expanse 23 millims.
