apical, reddish-brown shade ; the angular hind wings, and the well-marked 

 broad yellowish band common to both wings. 



Professor Zeller's description is so full that there is little difficulty in 

 recognizing his species, while Walker's was identified by a comparison with 

 his type in the British Museum.

3 <?. — Smaller than any species known tome; the fore wings slightly 

 excavated below the apex ; hind wings angulated a little and slightly scal- 

 loped. Body and wings pale pearly-ash ; head, prothorax, palpi, and antenna? 

 tawny-red. Fore wings crossed by three distinct wavy brown lines, ending 

 in three well-marked, long, oblique costal spots, the lines being angulated out- 

 ward betow the costa. A broad, submarginal, diffuse, tawny rust-red shade, 

 most distinct on the costa. A distinct dark-brown marginal line. Hind wings 

 crossed by three distinct brown lines, of which the middle is the better 

 marked, being much curved and wavy. Beneath paler, no rusty-tawny scales 

 on the fore wings, and only one well-marked line just before the middle of the 

 wing. The three lines present on hind wings, and a faint discal dot. 



Length of body, <?, 0.37 ; of fore wing, <?, 0.42 ; expanse of wings, 0.80

This is our smallest species, and somewhat resembles our common S. 

 bisignrtta Walk., having four costal spots, of which the fourth is large, rust- 

 tawny, while the body and wings are of much the same color. The hind 

 wings, however, are much less angular and the lines more distinct, while the 

 moth is very much smaller than usual.
