AntenncE inserted close to the anterior margin of the eyes, rather 

 short and capillary, composed of numerous cup-shaped joints, 

 clothed with long dilated and hairy scales (1, a). 

 MaxiU(S short, slender, and spiral (3). 



Labial Palpi porrected nearly horizontally, very scaly and trun- 

 cated, triarticulate, basal joint robust, curved, slender at the base, 

 2nd very long and stout, dilated towards the apex,3rd joint nearly 

 as long as the 1st, very slender and pointed, but nearly concealed 

 by the scales of the antecedent (4 and 4 a).

Fuscous ; tips of palpi, face and crown of thorax whitish : supe- 

 rior wings deep brown, the base glossy cinereous, with 6 or 7 

 cleft marks on the costaof the same colour, the 3rd continued to 

 the anal angle, leaving an oblique brown fascia across the centre, 

 dilated at the middle, the margins sinuated ; a large subtrigonate 

 mark on the internal margin silvery grey, some smaller irregular 

 markings of a similar colour towards the posterior margin, and a 

 black spot at the apex. 



In the Cabinets of Mr. Dale and the Author. 



The falcate tip of the superior wings and the large subtrigo- 

 nate or semiovate macula on their internal margin, are the 

 distinguishing characters of this genus, but some of the species 

 are destitute of the latter. The name is an adopted one, and 

 the genus not established ; I have transferred some of the spe- 

 cies it contained to another genus formed by the same party, 

 as they do not appear to belong to this group, which will pro- 

 bably form a division of Treitschke's genus Phoxopteris.
