Head much as in Anticlea, with no prominent vertical tuft, however, 

 but a well-marked interpalpal tuft. Palpi broad and stout, but short, 

 extending but little beyond the front; the third joint minute, concealed. 

 Antennae of male flattened, finely ciliated. Fore wings large, broader 

 than usual ; apex well produced, subacute ; outer edge slightly angular in 

 the middle. Hind wings small, distinctly scalloped, of the same form as 

 in Ochyria, but with the apex more obtuse ; the first subcostal venule is 

 much longer than the second, though shorter than in Ochyria and Rheu- 

 maptera ; second and third nearer together than usual; two subequal sub- 

 costal cells; second posterior discal venule bent, much as in Ochyria. Hind 

 legs with the tarsi nearly as long as the tibiae. Abdomen short and thick. 

 Coloration: either much as in Ochyria or both wings are crossed by numerous 

 wavy lines, much as in some species of Philereme. 



Our common /'. intestinata is readily recognized by the large tore wings 

 and the small scalloped hind wings, as well as the numerous wavy lines. P. 

 latirupta, which is like the European P. polygrammata, is marked much as 

 in Ochyria designata, and has longer palpi than in P. intestinata, and is evi- 

 dently a connecting link between the two genera. 



Larva. — " Caterpillars very long, filiform, a little attenuated in front, 

 smooth; head lenticular, flattened, having much-developed maxillary palpi; 

 living exposed on wood}' plants, very lively, and rolling themselves into a 

 helix at the least touch. Chrysalides subterranean." — Guene'e. 



Synopsis of the Species. 



Much like Ochyria dexignata, except that the hiud wings are scalloped P. latirupta. 



Much larger and darker, with more deeply-scalloped hiud wings and longer fore wings P. intestinata.

8 <? and S 9. — Antennae flattened and ciliated finely on the edges ; joints 

 two-thirds as long as broad. Palpi shorter and thicker than usual, blackish, a 



little paler at tip above. Fore wings pale cinereous; on outer half and at base
