Hind wings with a large double bunch of hairs pointing upward and down- 

 ward. Abdomen with a pencil of hairs around the under side near the tip. 



Length of body, <?,0.50; of fore wing, J 1 , 0.77; expanse of wings, 1.60 

 inches. 



This is very nearly allied to P. rhamnata of Europe. My specimens arc 

 all in bad condition, but the species is so well marked as to be recognizable 

 from the above description and the figure.

Head as in Philereme. Palpi much longer than in that genus, extending 

 far beyond the head ; third joint not easily distinguishable. Male antenna? 

 very finely ciliated. Fore wings short and broad ; costa much arched toward 

 the rectangular apex; outer edge much less oblique than usual, deeply scal- 

 loped. Hind wings long, extending well beyond the end of the abdomen ; 

 the inner edge long, with no ear or brush, the outer very deeply scalloped, 

 much more so than in any other genus of the subfamily, the points of the 

 scallops being very long and acute. Venation: much as in PMlereme ; the 

 inner subcostal cell much smaller than the outer. Hind leys as in Philereme. 

 Abdomen long and slender, witli lateral crests, and a well-marked, square, 

 long, anal tuft. Coloration: much as in Philereme. 



This genus differs from Pliilereme in the long palpi and abdomen, and 

 the very deep, sharp scallops in the hind wings especially. It comprises the 

 largest species of the subfamily.
