Distribution within Indian Ahea. — " Extremely rare in Sikkim. It has been

 it is fond of resting with outspread wings on the face of large boulders, from which 

 it is then scai'cely distinguishable " (de Niceville, Sikkim Gazetteer, 1894, p. 14 1). 

 " Dr. L. Martin caught a specimen in April, 1895, at the lower end of the Sibi 

 Kola, near Darjiling " (J. A. S. Bengal, 1895, 426). " Mr. J. Wood-Mason obtained 

 a female at Irangmara, in Cachar, in July ; another seen with outspreading wings 

 resting on the wall of a room in the bungalow at Lalla Mookh, in June, presenting 

 the appearance of a leaf overgrown by a fungus ; one male also taken on Nemotha 

 Peak in September" (J. A. S. Beng. 1887, p. 362). "Mr. J. L. Shirwell took a
