 sch/cegeri and some of the whitish Ethmias. If it can readily be controlled 

 it would be a very interesting and handsome addition to our fauna.

"Head with appressed scales, side-tufts loosely spreading ; ocelli 

 present; tongue developed. Antenna ^, in male bipectinated, towards 

 apex simple, basal joint stout, without pecten. Labial palpi long, curved, 

 ascending, with appressed scales, terminal joint shorter than second, acute. 

 Maxillary palpi rudimentary. Posterior tibiae clothed with long hairs. 



Fore wings with vein ib furcate, 2 from 4/5, 7 and 8 stalked, 7 to 

 hind margin, 9 absent, 1 1 from beyond middle. 



Hind wing i, trapezoidal-ovate, hind margin sinuate, cilia ^, veins 

 3 and 4 short stalked, 6 and 7 approximated towards base. 



Nearly allied to Cryptophasa.

Ptochoryctis tsugensis, new sp. — $-9- Expanse, 21-24 ni"''- 

 Head, thorax and labial palpi cream-white, latter dusted with fuscous 

 at base ; stalk of male antenn?e cream-white, narrowly fuscous between 

 joints ; pectinations fuscous, basal joint shining greenish-fuscous ; female 

 shining fuscous, faintly annulated with white. Abdomen cream-white, 

 posterior upper half of each male segment cupreous ; legs cream-white,

Fore wing shining white, marked with fuscous as follows : Over 

 upper vein of cell, from just beyond base to end of cell and continuing 

 over vein 6 with branches 7 and 8, with a faint scattering of dark scales 

 over 10 and 11. The lower vein of cell, from middle, is heavily overlaid 

 wiih the dark colour, spreading over veins 2 to 5, the interspaces being 

 more or less white. Vein ib from beyond base to tornus. The extreme 

 base of wing is pure white, except costa, narrowly edged with fuscous to 

 inner Y^,. A dark subterminal line begins at outer sixth of costa, curves 

 outward to vein 6, thence inward to tornus, paralleling margin, over each 

 vein the colour is darker. Between this and 'cilia the terminal space is
