Habits. — In the Khasi Hills the food-plant is Hedyotis 

 uncinella Hk. & Am., family Rubiacese, but Mell gives 

 Galium Linn, and Oldenlandia Linn., of the same family, as 

 the food-plants in China. Pupation takes place in a rough 

 cocoon on the surface, and in captivity among leaves of the 

 food-plant or in the upper corners of the box in which they are 

 kept. The moth rests in the same attitude as species of 

 Gurelca.
