Foodplant— Bamboo. 



A few caterpillars were collected from tlie top shoots of bamboo 



branches showing " dead heart " on 10th January. They had bored 



the twigs and were apparently hibernating. They continued to rest 



and pupated in March, emerging on 26th March.

 Foodplant — Tender bamboo shoots. 

 The caterpillars are very common in the rainy season, infesting 

 and boring new bamboo shoots as they come out of the ground. Gene- 

 rally a great many caterpillars are found in the same shoot bormg the 

 stem, completely hidden under the leafsheaths. They are responsible 

 for the death of a fair percentage of the new shoots.

Foodplant — Mootha {Cyperiis rotimdus). 

 The caterpillars of this Eucosmid moth were found boring the stems 

 in October.
