separated from llecahe by Capt. Watson. We have figured the larva and pnpa of 

 the two species. Both species appear to be almost equally common in the 

 N. Kanara District. We have a specimen of Silhetana caught in October, in which' 

 the ground-colour is pure white instead of yellow, the markings being normal " 

 (J. Bombay N. H. S. 1896, 571). 



Mr. L. de Niceville states that the larva of this species also feeds on " Poinciana 

 EEGIA, N. 0. LeguminosjB " (J. A. S. Beng. 1900, 252).

 Wet form taken at Karwar, Kanara, and a male from Coorg, also a female of the
