dlscal fold; the eell is open ; median nervure three branched, first and 

 second m. nervules thrown off top;ether at the extremity of the nervure; 

 third, more remote; a subraediau fold; internal nervure simple. Sec- 

 ondaries with the costal edge roundedly exerted at base, the costal ner- 

 vuse here bent upwardly and the tegument extended beyond it. The 

 real apices of the wing are rounded and comparatively retired, but the 

 external margin is pointedly projected beyond and below them at the 

 extremity of the subcostal nervure or its upper hnxnch or first nervule. 

 Below this the external margin is slightly excavate to extremity of the 

 lower branch or second s. c. nervule. Below this again the margin is 

 more widely excavate, rising to the exti'emity of the first median nervule 

 which is exerted to a point on a line with the extremity of the first s. 

 c. nervule. Beyond this the margin is even to internal angle. 



This genus is founded to receive a pretty little Phalaenid with beau- 

 tifully cut wings, apparently allied to Drepanodes Guenee and Timandra 



Walker. When at rest the primaries are spread out horizontally, but 

 the secondaries are depended, the internal margin folded over the ab- 

 domen ; thus a wide space is left between the anterior and posterior 



wings. 



Calledapteryx dryopterata, n. s. 



Entirely pale ochreous, sometimes entirely of a pale Avood brown. 

 Two transverse, dark, somewhat olivaceous lines cross the primaries at 

 the middle; these are subparallel, outwardly angulated, narrow, and 

 appear somewhat as the margins of an obsolete mesial band, being shaded 

 and the space between them partly filled in with dark irrorations on 

 the internal margin where the inner line is marked with two blackish 

 or darker disconnected spots. The outer line is obsolete below the dis- 

 cal fold. A faint semicircular dark line before the subapical excava- 

 tion on external margin. Fringes short, blackish. Secondaries resem- 

 bling primaries. The two median lines are continued, more distinct 

 and medially outwardly angulated and appear also to be obsoletely gemi- 

 nate with a paler included shade, the short fringes blackish. Beneath 

 paler than above, immaculate, very sparsely and coarsely mixed with 

 dark scales, or irrorate. Body and ap>pendages coucolorous with the 

 wings, immaculate.
