PORTHESIA XANTHORRHGA. wg 
Life History, etc. 
‘The larves of this moth were noticed to have completely 
defoliated Parottia Facquemontiana bushes in the Chatri 
forest of the Chamba State, North-West Himalayas, in April- 
May 1896. Mr. J. H. Lace, noting this defoliation, secured 
some of the larve and bred out some moths. This pest 
must have several other food plants since Hampson gives its 
reported habitat as throughout India, Ceylon, and Burma; 
also 
Java. | 
Further observations are required on the following peints :— 
i, The length of time spent in the larval state by the 
April-May caterpillars. 
2. Where the moth lays its eggs. 
3. The number of generations passed through during the 
year. 
4. The different food plants of the insect in different 
parts of the country, 

1 These notes on the life history were made by Mr. J. H. Lace, Conser- 
vator of Forests, at the time in charge of the Chamba Forest Division.
