Ramila ruficostalis (C. S. 1533). 



Plate 65, fig. 1. 



Foodplant — Bamboo. 



A few caterpillars were collected from the 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. 



Argi/roploce paragramma (C. S. 1631). 



Plate 65, fig. 2. 



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 boring the 

 stem, completely hidden under the leafsheaths. They are responsible 

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



Bactra truculenta (C. S. 1489). 



Foodplant — Mootha {Cyperus rotundus). 



The caterpillafrs of this Eucosmid moth were found boring the stems 

 in October. 



Heliothis ohsoleta.

In the neighbourhood of Pusa Heliothis obselota occurs in large 

 n'.nnbers only on gram and arhar {Cajanus indicus) of which they bore 

 the pods. Sometimes the caterpillars occur in small numbers on maize 

 of which the tender cob or the soft part of the top of the stem is bored. 

 Similarly they occur in small numbers on bajra heads which are bored.
