We have four species — rather closely allied.

B. Fore wings with a single, flattened and oblique, white 



or pale brown, dorsal blotch. F. immundana. 



B". Fore wings with a broad erect grey-brown or whitish 



dorsal blotch, followed by another. P. tetraquetrcuia. 

 B^. Fore wings with two large brightly white dorsal 



blotches, P. demarniana. 



B^. Fore wings with three dorsal connected paler blotches. 



F. crenana. 



1. P. tetraquetrana, Haw. — Expanse | to f inch (12- 

 16 mm.) Fore wings narrow; costa folded; red-brown or 

 black-brown with a large somewhat squared paler dorsal 

 blotch, followed by another at the anal angle. 



Antennce black-brown ; palpi, head, and thorax umbreous 

 mottled with paler brown ; abdomen grey-brown. Fore 

 wings elongated, and of even width ; costa folded at the 

 base and very flatly arched, apex bluntly angulated, hind 

 margin straight and but slightly oblique ; grey-brown, 

 black-brown, or red-brown ; basal blotch umbreous rippled 

 with white (but not extending to the costa, which is paler), 

 its outer margin perpendicular ; immediately beyond it is a 

 large somewhat squared dorsal blotch — greyish white, dusted 

 and rippled with dark brown atoms — central band very 

 oblique, almost pointed at the costa, reddish brown ; beyond 

 is a large pale cloud resembling the dorsal blotch, but jolaced 

 over the anal angle ; some tawny clouding runs into the 

 apex, and includes some minute geminated costal white dots ; 

 hind margin edged by a black line which is cut below the 

 apex by a white dash ; cilia smoky brown. Hind wings 

 smoky brown with paler cilia. Female similar but with the 

 costa plain. 



Undersides of all the wings leaden brown ; costa of fore
