seen two small yellow appendices, which are probably the app. 

 interned. 



Wings pale grey, with long grey fringes. Anterior wings clothed with 

 golden-grey hairs, the upper portion (above the groove) with nu- 

 merous, slightly attached, black scales ; these scales are absent in the 

 lower portion ; costal margin with a strong intumed fringe of blackish 

 scale-like hairs at the base, and a fringe of similar hairs on the ramus 

 clavalis closing over the groove ; veins yellow, especially those in the 

 lower portion, the apical ones fuscescent. Posterior wings clothed 

 with grey hairs, and with scattered black scales on the anterior 

 margin ; veins fuscous. (PI. II. fig. 7, details.) 

 I have two males of this extraordinary creature, which were 



given to me by Capt. A. M. Lang, H.E., by whom they were 



captured in North India.
